ASPIRE Guidelines for Assisted Reproductive Technology (ART) Laboratory Practice in Low and Medium Resource Settings
INTRODUCTION
Gaps in access to fertility care exist in nearly all health care settings but are particularly present in many countries of the Asia Pacific region. A crude measure of this access gap may be obtained from analysis of the number of IVF cycles per head of population (Chambers et al., 2021). Countries with high access gap are often called low or low medium resource settings. The prevalence of infertility appears similar across all regions though data are not available from some countries of the Asia Pacific region. (Mascarenhas et al., 2012) Healthcare resources are often referred to as the means available in a health system to deliver services to the population and when the health system does not meet the accepted norms of other global settings the system can be called a low-resource setting for health care (Lahariya, 2013). Access gap may be present when fully stimulated IVF cycles per million of population are below the global average, and where the measure is very much lower than global average high, access gap may exist. Factors which contribute to access gap in health care include financial shortage, paucity of knowledge, underdeveloped infrastructure, restricted social resources (tangible and intangible), influence of cultural and religious beliefs and practices, human resource limitations, suboptimal healthcare service delivery, geographical and environmental factors and research challenges. (Van et al., 2021). Use of telehealth will play a useful part in reducing access gaps (Mikhael et al., 2021).
Enabling access to fertility treatments in areas of reduced provision of care is complex and will take years of sustained effort in many cases. Expectations of care should legitimately be set at the same level as seen in high resource settings and this should be the ultimate goal. However, in the rehabilitative phase compromise may be acceptable in some settings and the goal of these guidelines, a collaboration of experts in the various disciplines and with wider consultation of the ASPIRE membership, is to set the minimum standards of an ART unit in a low resource setting.
The purpose of these guidelines is also to give easy access to existing guidelines within ASPIRE member countries and those of other regions for example, ASRM, ESHRE, RTAC, Alpha Scientists in Reproduction (Istanbul, Vienna, ALPHA, ISAR and Cairo Consensus) and these are provided in the Further Reading section at the end of this document. Underpinning this document are several guidelines on universal precautions, patient confidentiality, and good laboratory practice and these are also provided.
ASPIRE has developed these guidelines to provide clinical recommendations to improve the Standards of care within the APAC region. These guidelines represent the views of ASPIRE, which were achieved after careful consideration of available scientific evidence at the time of preparation (2022–2023). The aim of clinical practice guidelines is to aid healthcare professionals in everyday clinical decisions about appropriate and effective care of their patients. However, adherence to these clinical practice guidelines does not guarantee a successful or specific outcome, nor does it establish a standard of care. Clinical practice guidelines do not override the healthcare professional’s clinical judgment in diagnosis and treatment of particular patients. Ultimately, healthcare professionals must make their own clinical decisions on a case-by-case basis, using their clinical judgment, evidence available, and expertise, and considering the condition, circumstances, and wishes of the individual patient, in consultation with that patient and/or the guardian. ASPIRE makes no warranty, expressed or implied, regarding the clinical practice guidelines and specifically excludes any warranties of merchantability and fitness for a particular use or purpose. ASPIRE shall not be liable for direct, indirect, special, incidental, or consequential damages related to the use of the information contained herein. While ASPIRE makes every effort to compile accurate information and to keep it up-to-date, it cannot, however, guarantee the correctness, completeness, and accuracy of the guidelines in every respect. In any event, these clinical practice guidelines do not necessarily represent the views of all clinicians that are members of ASPIRE. The information provided in this document does not constitute business, medical or other professional advice, and is subject to change from time to time with the availability of newer evidence.

FACILITIES AND EQUIPMENT REQUIREMENTS FOR ESTABLISHING AN ASSISTED REPRODUCTION UNIT
Quick summary/at a glance
• | Specific room or space allocation aligns with the steps the patients take during an ART cycle. The infrastructure and equipment of an ART lab should support a strong quality management system (QMS) and allow for an optimal environment and minimizes the risk to the gametes and embryos. | ||||
• | Keywords: infrastructure, facility design, equipment, maintenance |
Objectives
An ART clinic should be designed to facilitate workflow of the Centre and consider both laboratory and clinical perspectives. Compliance with national or regulatory guidelines is required. A basic ART lab design should provide a safe and clean environment for biomaterials and for laboratory personnel.
Recommendations in regular practice for minimum standard of care
Facility
Floor plan design
The ART clinic and laboratory should be in a safe structure that complies to local building regulations.
i. | Clinical Procedure Room Should comply with surgical room establishment regulations prescribed in the local guidelines and regulations (Mortimer et al., 2016) | ||||
ii. | Main Laboratory The embryology laboratory should ideally have a designated area adjacent to the clinical procedure room and if this is not possible the facility should have procedures to ensure safe transfer of gametes to the laboratory. | ||||
iii. | Andrology Laboratory Semen analysis should be performed in a separate designated area. (De Los Santos et al., 2016) Whether sperm processing needs a separate area or not depends on the service scale and resources available of the centre. | ||||
iv. | Semen collection rooms The semen collection room should provide adequate space and a relaxed environment and ideally connected to the andrology laboratory via a hatch (Mortimer et al., 2018) | ||||
v. | Consumables Storage Area The storage area for consumables should be ideally separated from the embryology laboratory and have good ventilation. Moreover, consumables should not be stored near the diesel generator or other locations exposed to toxic fumes or moisture. However, given the uniqueness of Asia-Pacific area; an integrated area or separated rooms is under the centers’ own discretion. |

Consumables
Consumables should be sterile and tested for human culture purpose. If not tested for human grade, bioassay such as sperm survival test should be applied to minimize cytotoxicity to human gametes.
IVF laboratory basic design
Building materials
i. | All building materials should be selected to avoid VOC emission including vinyl flooring and wall paint should be “zero” VOC. | ||||
ii. | Materials for the cleanroom should use non-toxic material e.g., stainless-steel tubing for gas line. | ||||
iii. | Sealing should be VOC free with sufficient air-tight property to prevent outdoor contaminants or losing air pressure (ESHRE, 2015). This includes a hard lid or sealed ceiling. |
Gas delivery system for CO2, N2 and Tri-Gas incubators
i. | Gas cylinders should be stored separately from the clean room laboratory if possible. Gas cylinders can be located within the laboratory if fittings are disinfected. Ideally, alarm systems should be installed for low oxygen and high CO2are installed in the laboratory and the liquid nitrogen tank rooms. | ||||
ii. | It is suggested to have a gas supply unit with an automatic change-over unit to prevent any disruption of gas supply (ESHRE, 2015). |
Power supply
Sockets should be sufficient for all the essential electronic equipment present in the laboratory. A back up UPS or generator is strongly suggested to ensure undisrupted power supply for all the critical equipment in the embryology lab such as ICSI machine for an appropriate amount of time. For areas with unstable power supply, a generator for backup power supply (diesel) is essential be isolated for the ART lab (Bai et al., 2020).
Environmental control (air quality, temperature, humidity, and light)
ART laboratory should be equipped with independent heating, gas phase filtration, ventilation, and air conditioning (HVAC) to control the air changes (∼15 times/hour, 20% fresh air), temperature (20–24∘C) and humidity (40–60%). Air handling unit with HEPA filtration system should be installed to maintain positive pressure (Pa) in the laboratory and control the particle counts (preferably less than particles larger than 0.5m to 10m per cubic foot of air) and micro-organisms in the air less than 5 colony-forming units/90mm petri dish in passive sampling method to control. The light source in ART lab should be dimmable to minimize light exposure to oocytes and embryos (ESHRE, 2015).
Ideally, HVAC system should have potassium permanganate/alumina filter in addition carbon filter to control VOC.
Equipment for gamete/embryo manipulation and culture
General Requirements
The type and number of devices should be appropriate to the workload and backup units of mission-critical equipment should be considered (e.g., micromanipulators, microscopes, laminar flow cabinets, incubators, refrigerators, freezers, LN2 tanks, etc.).
The availability of backup equipment in case one particular unit fails should be taken into account.
Equipment location
For optimal efficiency of laboratory operations, equipment location must be carefully planned for safety and ideal workflow in each working area.
Equipment
Refer to section 1.3.b
Maintenance
i. | Access to service providers for regular and emergency maintenance should be available. | ||||
ii. | Regular laboratory equipment maintenance schedule (either in-house or outsourced) should be in place and where applicable calibration and validation against either internal or preferably external standards should be performed. | ||||
iii. | Records and documents of inspections, maintenance, repairs, calibration, and validation must be retained. | ||||
iv. | Filters for incubators, HEPA filters, HVAC systems, and air purifier must be changed according to the local conditions, time of usage and manufacturer’s guidelines. |
Systems
Medical records system
i. | A permanent and secure means of keeping records of the embryology laboratory must be in place. These may be manual or electronic medical records (EMR) with appropriate backup provision (both onsite and off-site), or paper based. | ||||
ii. | EMR software to store patient medical records by electronic methods is required. A more advanced EMR system specially designed for IVF is much more user-friendly and fully supports the activities and administrative tasks of the involved personnel is preferred. | ||||
iii. | The electronic data can be extracted directly and correctly for evaluation of laboratory key performance indicators (KPI) and staff competencies. |
Witnessing system
i. | Methods of ensuring gamete and embryo traceability must be in place—these may be manual signed double witnessing system should be mandatory. Other methods such as photographic records, or electronic witnessing systems (EWS) can also be in cooperated. | ||||
ii. | Analysis of the operating time of each IVF procedure documented manually or electronically can be used as KPI for QC. |
Alarm systems
i. | The equipment related to cell/embryo viability and development, such as incubators cryostorage tanks, and refrigerators for medium storage, must be constantly monitored and for abnormal conditions, such as the variations (low and high) in pressure levels of CO2 and temperature. A staff member shall be on call 24/7 to ensure the safety of embryos. | ||||
ii. | Low oxygen tension alarms with supportive contingency plans are recommended in areas where refilling of cryostorage tanks with Liquid Nitrogen occur. | ||||
iii. | High CO2 tension alarms with supportive contingency plans are required where CO2 is piped into the laboratory (CO2 cylinders safety) (optional). |
STAFFING IN THE IVF LABORATORY
Quick summary/at-a-glance
• | Laboratory staffing is a key element in the IVF laboratory and contributes greatly to the success of fertility treatments. Important factors include: leadership, teamwork, education and training, emphasis on work safety and employee wellness. | ||||
• | Keywords: staffing level, staff proficiency, education level, training, workload, employee wellness |
Objectives
Complex Techniques including ICSI and PGT, requirements in risk management e.g., patient consent, double witnessing, as well as frequent communications with the clinical team and patients generate a high amount of workload to the laboratory staff. At the time of writing these guidelines, there is no established guidance with an overview on staffing in the embryology laboratory in ASPIRE membership countries.
In this section, we have established recommendations on staffing suitable for various laboratory settings.
Recommendations for minimum standard of care
Staff educational and experience requirements
Table 2 Lists a description of an embryologist and the appropriate minimum educational and skill levels to be adopted universally in the APAC region. Each ASPIRE member association or organization shall determine the eligible relevant majors for each category of laboratory profession. This may be influenced by each country’s government regulations and requirements.
Title | Minimum education | Minimum experience and training |
---|---|---|
Junior/Trainee Embryologist | B.S. degree in a relevant major of biological or medical sciences | None |
Embryologist | B.S. degree in a relevant major of biological or medical sciences | 1 year of documented human embryology experience; 10 cycles of each independently performed technique (e.g., 10 ICSI, 10 TE biopsies) |
Senior Embryologist | B.S. degree in a relevant major of biological or medical sciences | 5 years of documented human embryology experience; meet all criteria of Embryologist |
Embryology Lab Supervisor | Master’s degree in a relevant major. Recommendation: Advanced degree or Ph.D degree in a relevant major of biological or medical sciences | 5 years of documented human embryology experience, including 1 year of supervisory duties under lab director/supervisor guidance; meet all criteria of Senior Embryologist |
Embryology Lab Director | Advanced degree in a relevant major or in compliance with national rules. Recommendation: Doctorate degree or Master’s degree in a relevant major of biological or medical sciences | 6 years of documented human embryology experience, including 2 years of supervisory duties under lab director guidance; meet all criteria of Lab Supervisor. ASPIRE will determine grandfathering of existing lab directors without advanced degrees. Off-site lab director: define no. of visits, Continuous remote monitoring, monthly reviews and quarterly visits. |
Role and responsibilities of laboratory leadership and staff
The laboratory is directed and supervised by an experienced scientist or medical doctor who has sufficient knowledge in IVF laboratory techniques and management, and complies with national legislation or regulation applicable to the location of the laboratory. The director ensures an adequate number of staff to safely undertake the laboratory workload. All new staff are given comprehensive initial training, and staff are evaluated for competency annually. Continuing professional education in interactive settings is recommended for all laboratory personnel, even if not mandated by the national rules. Besides the duties and responsibilities outlined in this section, the laboratory should have an organizational chart, and written procedure describing the responsibility of each individual laboratory staff, and line of responsibilities and reporting, with sections including but not limited to hands-on techniques, administration, training, quality management including start-up and shutdown checklists, negative outcome handling and basic troubleshooting, and communication.
i. | IVF Laboratory Director The IVF Laboratory Director is responsible for all aspects of quality and functions in the IVF laboratory. The director should be able to provide guidance on hands-on and managerial tasks, evaluate laboratory findings, interpret quality assurance and control (QA/QC) data and adverse events, conduct corrective actions, monitoring of success rates and laboratory KPIs, and communicate internally with the laboratory team and externally with clinicians and patients. Off-site Lab Directors shall continuously monitor lab operations and outcomes, review data at least monthly and conduct on-site visits at least quarterly. Typical responsibilities of the laboratory director include :
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
ii. | IVF Laboratory Supervisor The laboratory supervisor works closely with the laboratory director to provide oversight of laboratory operations. Laboratory supervisors are clinical embryologists who have acquired supervisory training and/or accumulated a significant amount of experience in managerial functions in the IVF laboratory. Additional educational requirement and continuing training are recommended and may be required based on each clinic’s needs and national rules. Under authorization and delegation by the laboratory director, the supervisor may oversee some of the daily directing duties. In case of an offsite lab director, the lab should have an onsite lab supervisor (ASRM, 2022). Typical responsibilities of the laboratory supervisor include Clinical Embryologist duties, plus :
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
iii. | Clinical Embryologists Clinical embryologists perform hands-on techniques with proven and latest technologies, and quality management tasks in the daily clinical practice. Training, of new staff, current staff competency evaluation, and continuing education are required for the clinical embryologists to perform duties to meet the highest standards. Based on each individual’s education and skill levels, proficiency, and assigned roles in the laboratory, a clinical embryologist usually starts as a junior/trainee embryologist, progresses to become a fully trained embryologist and then progresses to be a senior embryologist. Junior embryologists should execute tasks under the guidance of the laboratory director, supervisor, or senior embryologist to ensure the quality and safety of practice. Typical responsibilities of a fully trained clinical embryologist include :
|
Recommended minimum number of embryologists based on workload
Each lab should factor in the workload of all lab procedures, paperwork and other areas contributing to the complexity of IVF laboratory, to determine an adequate number of staff. To avoid work burnout, key considerations should include sufficient staffing for witnessing procedures, individual performance, teamwork, leave cover, and staff wellness. Staff numbers are often calculated in full-time equivalent (FTE). Part-time and managerial staff should be calculated by their actual hands-on percentage, e.g., a lab director/supervisor with 50% hands-on duties should only count as 0.5 FTE.
While it is difficult to precisely estimate each laboratory’s FTE needs, we propose a simplified “cycle point” system, taking into consideration the major IVF laboratory procedures, for a recommended minimum number of embryologists. Each fresh conventional insemination IVF cycle or oocyte cryopreservation equals 1.0 cycle point. Each FET is 0.5 point. For fresh cycles, each ICSI case adds 0.1 point and PGT case adds 0.5 point of weight to the cycle. Note: Andrology and endocrine testing tasks are not included in this calculation.
• | Example: A lab performing 150 fresh cycles per year, including 100 ICSI and 40 PGT cases, and additional 60 FETs, will be calculated as . |
The recommended minimum numbers of embryologist in the IVF laboratory are listed as below, with clinics having regular settings with sufficient resources, and with low resources setting performing treatment cycles in batches or utilizing part time external sources. (Table 3) (Yamada et al., 2022).

QUALITY MANAGEMENT IN THE IVF LABORATORY
Quick summary/at-a-glance
• | Quality Management System (QMS) is a fundamental and core aspect of an ART program. This section summarizes the day-to-day operational management of the personnel, environment, procedure, and documentation in an embryology laboratory. | ||||
• | Key points, keywords: quality management system; standard operating procedures; documentation; traceability; witnessing. |
Background and specific objectives
Successful ART programs depend on the controlled conditions in every aspect of the treatment. The QMS involves a system whereby all levels of an organization are committed to ongoing quality improvement. This includes administration, patient management, laboratory procedures and reporting.
Although there are several documents providing guidance on QMS for the embryology laboratory in some ASPIRE membership countries, the guidance does not exist in some countries. There are needs of uniformed guidance to be utilized by clinics in the APAC region.
Recommendations minimum standard of care
Quality manual
The QMS must be documented in a quality manual. The manual should at least include the organizational structure, management, personnel, equipment, and consumables, buildings and facilities, traceability of all samples, documentation under document control, records, and review of outcomes and should be systematically reviewed annually. QMS should include the format and process of audit, e.g., frequency and schedule, audit team consisting of clinicians, embryologists, and administrators. (ASRM and SRBT, 2022; ESHRE, 2015; Mortimer et al., 2015)
Written, authorized, signed, and up-to-date SOPs should exist to optimize outcomes. SOPs should include daily quality control methods for all procedures performed in the lab. All new protocols should be validated by parallel testing prior to clinical implementation.
Organizational structure
A clear organizational structure showing lines of accountability and reporting should be presented. It is not necessary to have a separate individual for each position. In a small organization, an individual can have multiple roles. (Elder et al., 2015; ESHRE, 2015; Mortimer et al., 2015)
Management
The responsibility of management is to measure the effectiveness of the ART programs. Good management optimizes the provision of services according to the available resources. (ASRM and SRBT, 2022)
Personnel
The transparent procedures for the staff recruitment should be established. Each position should have a clear description on duties and authorization of tasks to be performed. There should be annual evaluation of performance, maintenance of record of competencies, achievements, and continuous education (ASRM and SRBT, 2022; ESHRE, 2015).
Equipment and consumables
All details of the equipment and consumables were listed in a separate section of this guideline (refer to 1.3.b) and this equipment should be fit for this purpose. It is preferred the all equipment is externally validated through third party service providers. After clinical use for a specified period, each piece of equipment should be monitored for performance, interval service maintenance, and calibration. All equipment should have a back-up plan in the event of failure, and critical equipment be supported with either an UPS or emergency generator. All consumables should be accompanied by a Certificate of Analysis, expiration dates and lot numbers of all reagents and media and should also be MEA tested by the manufacturer.
Buildings and facilities
Maintenance of buildings and facilities are important to avoid introduction of contaminants and to provide a safe environment for both embryos and staff. Annual maintenance of the HVAC system and any controlled environmental chambers as well as annual testing of air quality, is required. Annual general maintenance is also required to prevent natural wear and tear, mould, and insect infestation prevention. All facilities should have emergency evacuation plans under extreme conditions such as earthquakes, fire, flooding, volcanic activity, and war. (ASRM and SRBT, 2022; ESHRE, 2015)
Samples traceability
All samples entering the ART process must have maintenance of traceability. The following three strategies address the requirements :
i. | Right patient, right procedure Right patient, right procedure has evolved as a mechanism to prevent mistaken identity in healthcare. It involves the proactive identification of patients and the procedure they are scheduled for. It usually takes the form, “Hi my name is ——— and I just need to confirm your name, date of birth and what procedure you’re having today.” The question is always asked in the presence of another staff member, who listens to the reply and checks the details on the paperwork, along with the questioner. If the procedure is being carried out in an operating theatre, there is a ‘time out’ where everybody stops to confirm that the correct patient is present for the correct procedure. A 3-point identification system provided at all interactions (name, DOB and patient ID number or address) is recommended. A translator is required when patient does not speak the common language. | ||||
ii. | Double witnessing Double witnessing of three identifiers on all gamete and embryo movement is essential to ensure that there are no ‘mix-ups’ during ART procedures. There are many methods for double witnessing including two independent people intent witnessing or electronic witnessing. The witnessing step must be recorded either by initials, signature (either manual or electronic) or photographic. | ||||
iii. | Unique documentation Unique documentation for each procedure should be sorted thoroughly with unique identifiers. Identifiers may also be unique for each patient cycle or indeed each individual embryo if more extensive tracking is required (such as the case with PGT embryos). An individual patient can have many procedures and tracking needs to cover not only the individual procedures, but also the sum of the procedures, such as cumulative pregnancy rate per patient. |
Documentation
Within the organization, there will be well over a hundred documents involving information given to patients, quality manual, clinical, nursing, counselling, administration, laboratory procedures and consent forms. These documents are continually updated to reflect the quality management cycle.
The document control system with a hierarchy of authorization needs to be established to update and re-issued the documents with a serial number. A simple protocol such as only printing a document as required and no ‘stock’ of copies could help to ensure that the correct version of the document is handled. Document control with time-stamp on revision and/or locked for editing is recommended (ASRM, 2021; ASRM and SRBT, 2022).
Records
The QMS requires the storage of procedure records. Medical records have defined retention period depending on national legislation. All records must have traceability on the outcomes, and the procedure down to a particular batch or lot number for critical equipment and consumables. Records can be stored electronically provided there is a appropriate on-site and off-site backup of the data (ASRM, 2021).
Data should include :
• | Morphological and developmental characteristics, including stage and abnormal events, of gametes and embryos | ||||
• | Detailed information on the procedures, including timing and the staff involved | ||||
• | All information needs to comply with the requirements of national data registries. |
Review
All aspects of a QMS should be reviewed regularly, preferably using a quantitative system such as KPI regularly. The ESHRE and Alpha scientists in Reproductive Medicine published the Vienna consensus that provide the competency and benchmark value for KPIs which the laboratory can used as external benchmarks.
However, the organization itself is responsible for the KPIs they choose to use in the various important areas of the clinics such as :
• | Unit success | ||||
• | Laboratory performance | ||||
• | Clinical performance | ||||
• | Business goals | ||||
• | Patient satisfaction | ||||
• | Staff satisfaction |
DOCUMENT CONTROL AND CONSENT
Quick summary/at a glance
• | QMS and associated processes require an institution to “maintain a set of procedures, policies, and rules that are essential to support the functioning of processes and also to ensure confidence that the processes are being executed as intended.” | ||||
• | Keywords: Document control, KPI, SOP, audit, disaster management |
Background and specific objectives
QMS and associated processes require an institution to “maintain a set of procedures, policies, and rules that are essential to support the functioning of processes and also to ensure confidence that the processes are being executed as intended” (ESHRE, 2017).
Document control is a system that ensures only relevant policies, forms, and procedures are being used and ensure that records of approval and review by the laboratory director are being maintained. This is usually achieved using a control log containing all procedures, forms, and policies with the respective location. A defined process is necessary to make sure that all personnel have proper knowledge about the respective procedures and policies.
The safety aspect and success in an ART program are highly important and only a well-executed TQMS can help in achieving this.
Recommendations for minimum standard of care
Standard operating procedures (SOPs)
The first step in TQMS is to have SOPs in place. SOP is a document that enables uniformity in practice. Errors and risks are minimized when operating procedures are standardized. The SOPs must be developed in a standardized format. SOPs must be modeled, based on scientific evidence and must be updated regularly. A printed copy of SOPs should be accessible to the authorized staff of the IVF center. An electronic copy should be maintained with password protection which ensures the safeguarding of the organization’s intellectual property.
Procedures and process maps
Every process must be mapped using the flowchart method. The process map lists the descriptions of procedures, how they should be undertaken and indicates the expected outcome (performance indicators). Documenting every step as described in the process map is essential and this is the first step in troubleshooting in any clinic.
Documentation/data capturing
Documented information must be maintained by the organization in order to provide evidence of the results achieved (records). Documentation is essential to gain confidence that all processes are being executed as planned. Several documents are part of the IVF cycle and this segment specifically deals with the laboratory-related documents that are necessary to implement TQMS.
At the start of each day, as a routine practice, a checklist must be verified before the lab starts functioning. This will include verifying appropriate environmental conditions (room temperature and humidity), equipment function, and appropriate levels in gas cylinders and LN2 tanks. A list of essential checklists for an IVF lab is mentioned below (ASRM, 2022).
Essential laboratory related documents for andrology laboratory and embryology laboratory
• | Copy Of All Relevant Licenses of the Clinic | ||||
• | Daily monitoring Log Sheets for all equipment in the lab | ||||
• | Internal and (where applicable) external calibration of all equipment in the lab | ||||
• | LN2 log sheets- Refill details and levels | ||||
• | Culture media log sheets—Batch lot, Batch number, expiry date of media | ||||
• | Stock procurement register—Date of receipt, Batch, and LOT numbers | ||||
• | Andrology laboratory worksheets—Semen Analysis, semen preparation for intrauterine insemination, Semen freezing worksheets, TESA sperm processing, and freezing worksheets | ||||
• | Embryology Worksheets—OPU, ET, Vitrification/warming, FET, PGT/Embryo Biopsy | ||||
• | Cryopreservation Worksheets—Embryo, semen, TESA, and oocyte cryopreservation | ||||
• | Annual Maintenance Schedule of the lab | ||||
• | Event log and procedure update list to record special events and changes in the lab. |
The proper functioning of a lab can be ensured by a timely audit of the data captured during daily QC. Laboratory daily QC values must be compared with a peer group, when possible, to confirm accuracy on a regular basis (often monthly).
Records or data management must be compliant with local statutory and regulatory authorities. Document control systems that indicate evidence of implementation, approval, and review of internal and external documents should be done at timed intervals.
The Organization/ART Unit should undertake regular reviews of treatment outcomes. It should provide evidence of implementation and review of policies and procedures to :
• | Identify, collect, analyze, and review data to keep track of treatment procedures, practices, and treatment outcomes at least once a year. | ||||
• | Benchmark the Organization’s/ART unit’s clinical outcomes against the reports of the national registry if available and pinpoint areas and opportunities where improvement can happen. In cases where the clinical outcome falls below the 25th percentile of suggested benchmarks (ref to Benchmarking section 9), the ART unit has to carry out a root cause analysis to know why the results fall in this range and provide a corrective action plan or come up with a rationale for not doing so. |
Data reporting
The organizations/ART Unit should report the captured data of every IVF cycle to the national registry of their country in the stipulated time frame (if applicable). Nevertheless, patient confidentiality should not be breached. Apart from IVF cycle data, (patient demographics, gamete, and embryo information), it is very important to report pregnancy outcomes of all ART interventions.
Key points:
The data captured has to reported to the regulatory body as per the respective country’s national norms at specific time intervals.
Confidentiality with documentation
Data capture is necessary but it should be compliant with any legislation pertaining to patient privacy. Patient information should not be used anywhere outside the IVF unit once the audit is complete. The information that is shared as a result of a clinical relationship is considered confidential and must be protected. The information can take various forms (including identification data, diagnoses, treatment and progress notes, and laboratory results) and can be stored in multiple media (e.g., paper, video, electronic files).
Report generation
Labs should have an adequate manual or electronic system to ensure test results are sent precisely and reliably from the point of data entry to the final report destination in a timely manner. All test reports must include the following items: results; patient name and unique identifier; name and address of the testing laboratory; test report date; date of performance; units of measurements; and reference intervals or normal values. Test reports should include signed and verified by the person performing the test. In case of any error in a patient’s laboratory report, the authorized person ordering the test or the individual using the test results must be immediately notified.
Reports must be issued promptly after corrections. The original as well as the corrected report must be maintained. All test reports of patients should be easily accessible for surveys or audits.
Key points:
Labs should have an adequate manual or electronic system to ensure that the test results are sent precisely and reliably from the point of data entry to the final report destination in a timely manner.
Incident reporting, corrective and preventive action
Incident Reporting (IR) is a reactive tool and is well-accepted in all critical industries such as ART that has minimal tolerance for errors. A system to report the incident and near misses create corrective/preventive measures helps in minimizing errors in an IVF cycle.
Patient information documents
This must include but not be limited to :
• | Processes, costs, risks, and outcomes | ||||
• | Drugs and side effects | ||||
• | Availability of individual counselling and support groups | ||||
• | Patient rights and responsibilities including data privacy policy, as detailed by local regulatory authorities | ||||
• | Patient consenting process and how their data will be collected, stored, and used |
Consents
The Organizations/ART Unit must :
• | Ensure that treatment commences only after a valid consent is obtained | ||||
• | Ensure that consent is written, signed, and dated. Documentation must include a signed statement by the treating clinician confirming that all relevant provision of information and counselling requirements has been satisfied. | ||||
• | Have a process whereby clinical staff ensures that valid consent is obtained from all patients, donors, and/or surrogates (and, where relevant, their spouses or partners) before treatment commences | ||||
• | Consent form for participation in Embryo cryopreservation services and future options. In case of death, divorce or loss of contact with medical center. | ||||
• | Provide patients with information that is accurate, timely, and in formats appropriate to the patient | ||||
• | Provide evidence of implementation and review of policies and procedures which define the consenting process (Olofsson et al., 2013). |
Record keeping
The embryology laboratory must retain records of all its policies and procedures as well as personnel employment, training, evaluations, and continuing education activities. In addition to this, documentation of the proper identification, outcome, and disposition of all gametes, gonadal tissue, and embryos is important (Olofsson et al., 2013).
The laboratory must maintain these records for a period according to local legislative requirements or for 10 years beyond the final disposition of all data obtained during each patient’s ART cycle, whichever is later.
All paper records must be maintained on-site or in a secure, audited off site facility, and electronic records must have appropriate safeguards against data loss. In the event that the laboratory ceases operation, provisions must be made for these records to be maintained according to the time frame required.
DISASTER MANAGEMENT
Quick summary/at a glance
• | Disasters, minor or major happen in unforeseen circumstances. It is prudent for all ART units including those in low resource settings to formulate a policy on disaster management to ensure safety and protection of personnel and patients, embryos, oocytes, and sperm, and to protect and secure important documents and critical equipment. | ||||
• | Keywords: Disaster, quality assurance, safety |
Background and specific objectives
Disasters are serious disruptions to the functioning of a community that exceed its capacity to cope using its own resources. Disasters can be caused by natural, man-made and technological hazards, as well as various factors that influence the exposure and vulnerability of a community (ref www.ifrc.org accessed 1/3/23). The impact of disasters is magnified in low resource settings. (WHO document). Perceived threats and disasters will vary according to the environment, population, political and other factors. All clinics in LRS need to have considered disaster mitigation unique to their location and resources. Disaster mitigation includes risk assessment, prevention of disaster and preparedness for disaster and the document prepared by the WHO is a useful framework for the clinic to use. The immediate intervention of response to disaster should also be considered. Rehabilitation and reconstruction as part of the disaster response can be developed after the immediate response. Disasters can occur beyond the control of the ART units that require action to be taken to limit damage or loss. Such disasters can affect ART units in several ways including the interruption of clinical procedures, damage to critical equipment resulting in disruption of the culture and storage of gametes and embryos, medications, and reagents. Safety and protection of personnel and patients from disasters or imminent threats is of paramount importance.
Contingency and scenario analysis is the key to disaster management. To minimize risks, ART units should implement an emergency action plan that include a risk assessment programme and risk management strategies appropriate for their geographic locations to protect patients, personnel, and specimens (embryos, oocytes, and sperm) in the case of an emergency, natural disaster, pandemic, or other potentially devastating event.
The objectives of an emergency action plan should be to provide for (in descending order of importance) the safety of personnel and patients, fresh and cryopreserved embryos, oocytes and sperm, and critical equipment and records.
Recommendations in regular practice for minimum standard of care
Implementation, monitoring and quality assurance
SOP for an emergency action plan should be developed by ART units. The emergency plan should include (1) providing for the safety and protection of personnel and patients; (2) the safety and preservation of fresh and cryopreserved oocytes, sperm, and embryos; and (3) the protection and security of important materials, such as patient records, laboratory records, financial and operational documents, and facility equipment.
Outline of the emergency plan
i. | The safety of personnel and patients is of utmost concern. Provisions for their safe evacuation from the unit premises should be made known to personnel e.g., escape routes plan in the building. The emergency plan should provide for safe transfer of samples held should that be necessary. | ||||
ii. | All personnel should have knowledge of the Emergency Plan and understand their responsibilities in the event of an emergency or natural disaster. For example, emergency drills like fire safety drill should be conducted regularly. | ||||
iii. | All personnel should know whom they are to contact during and after an emergency to report their status (i.e., their safety, contact number, whereabouts, ability to return to work). Such contact should be made by personnel as soon as possible after reaching a place of safety. A formal risk assessment accompanied by a risk mitigation plan on the premise should be undertaken to ensure safe return to work (Sharma et al., 2017). | ||||
iv. | Regular revision of the emergency plan is necessary and arrangements should be made with another IVF lab for emergency transfer of fresh & frozen gametes and embryos (ESHRE, 2015). |
SAFETY AND INFECTION CONTROL
Quick summary
• | Policy and procedures for prevention of infection transmission are required. | ||||
• | Safe handling of liquid nitrogen requires training and policy and procedures including avoidance of low oxygen tension is critical for staff safety and alarms and policy and procedures are required. |
Background and specific objectives
Reduction of risk of transmission of infection between clinic personnel and patients
Policy and procedures for the safety of personnel from infectious diseases and contamination within the ART unit should also be provided (European Council, 2019). Human body fluids, such as semen and follicular aspirate, are potentially infectious and shall be handled and disposed using standard universal precautions.
The main diseases potentially transmitted to staff by patient samples in the ART laboratory are hepatitis B, hepatitis C and HIV (Junk et al., 2009).
All patients shall be screened for HIV, hepatitis B and C, syphilis, and other sexually transmitted diseases according to disease prevalence in the community and other infectious diseases prior to treatment commencement and at regular intervals thereafter. Pipetting by mouth is not recommended when handling oocytes and embryos (Jindal et al., 2016).
Universal precautions should be applied when handling all potentially infected samples.
This includes: (Elder et al., 2005)
1. | Limitation of access to laboratory to trained staff only, especially during working procedures. | ||||
2. | Laboratory staff should change in clean operating theatre dress and operating theatre shoes at the beginning of the day and change at the end of the day or when the laboratory is exited. | ||||
3. | Handwashing facilities should be available at the entrance to the laboratory and in a cool area to reduce microbial contamination. | ||||
4. | Gloves should be worn when doing sperm prep, OPU and ET – but at other times better to not wear gloves e.g. when handling pipettes and dishes due to loss of sensitivity to touch. | ||||
5. | Instruction of staff in handwashing techniques to reduce cross contamination. | ||||
6. | Laboratory equipment and surfaces should be easily cleanable and cleaned regularly using non-toxic agents. | ||||
7. | Floors should be cleaned regularly with a suitable low VOC cleaning agent and kept clear of unnecessary equipment, supplies, and cardboard boxes. | ||||
8. | Sharps containers should be available for used sharp items. All staff should be advised to take precautions to prevent accidental wounds from sharp instruments. All sharp and fragile objects such as needles, glass pipettes, glass slides and cover slides are to be disposed in sharp containers after use. All potentially hazardous items such as gloves, semen containers, culture dishes and test tubes shall be used once only and disposed as potentially infectious. | ||||
9. | Adequate training of staff in handling pathogenic materials | ||||
10. | Perform aerosol generating procedures in a biological safety cabinet | ||||
11. | It is strongly recommended that all laboratory personnel who work with human samples shall be immunized against hepatitis B (Andersen et al., 2022). | ||||
12. | Known infectious cases should be “temporally” isolated and performed as the last case of the day. | ||||
13. | Development of a laboratory code of practice to reduce disease transmission which includes a policy on management of spills and reporting of incidents which are associated with increased risk or adverse event (Elder et al., 2005). Review of incidents with non-adversarial risk assessment, root cause analysis and quality management (GLP, 2022). |
Prevention of aerosol transmission of infection between staff and patients
• | Development of policy and procedures according to the clinic’s risk assessment should occur to cover the issues below: | ||||
• | All staff should be offered vaccination against COVID-19, influenza, rubella and varicella where possible. | ||||
• | Where appropriate history screening for respiratory infection of staff and patients should be performed and mask wearing required with symptomatic or at-risk patients. | ||||
• | Cough etiquette should be promoted. | ||||
• | Tuberculosis poses a special risk in laboratories in Asia Pacific which has high representation of global burden of tuberculosis particularly in India, China, Pakistan, Philippines, Indonesia and Bangladesh (Jeremiah et al., 2022; WHO, 2022). | ||||
• | There should be a person nominated with overseeing each staff member’s risk of tuberculosis in at risk regions. | ||||
• | Policy and procedure for ensuring reduction of risk of transmission of tuberculosis between staff should be developed according to the local risk. |
Prevention of cross contamination between patient samples
Whilst samples are being handled precautions need to be taken. See section 6.3.a While risks of cross-contamination in storage tanks are more perceived than real, IVF laboratories should make an informed decision on their risk mitigation strategy. Though there are no reports of cross-contamination of oocytes or embryos in LN2, the following points provide evidence for theoretical risk.
• | Cross contamination occurred in open vs closed vitrification devices in a bovine model where high viral titers and bacterial and fungal loads were experimentally introduced to liquid nitrogen (Bielanski et al., 2000, 2003). These experiments led to a recommendation to use closed systems and/or sterile LN2 (Bielanski and Vajta, 2009). | ||||
• | Hepatitis B transmission occurred in LN2 storage of large containers of serum (Tedder et al., 1995). | ||||
• | Transmission in the laboratory when handling samples while following universal protocols is unlikely; however, HCV was transmitted to another patient in an assisted reproduction clinic during routine phlebotomy (Lesourd et al., 2000). | ||||
• | While theoretical in nature, to date there are no reported cases of disease transmission caused by LN2-mediated cross-contamination (Cobo et al., 2012; Penzias et al., 2021b; Pomeroy et al., 2010). Unlike semen cryopreservation, which involves a large volume of leukocyte-containing specimens that could possess significant viral loads, oocyte and embryo vitrification involve nanoliter to microliter volumes of highly processed samples (Joaquim et al., 2017). The vitrified samples oocytes and embryos are essentially non-infectious, as evidenced by undetectable viral sequences in seropositive HIV, HCV, and HBV patients (Cobo et al., 2012), making the risk of cross-contamination improbable. Cross-contamination is therefore of significance when semen samples are stored. | ||||
• | ASRM guidelines advise separate storage but stop short of endorsing it as a recommendation: “While there is insufficient evidence to endorse the recommendation, best-practice guidelines recommend that semen and embryos from patients infected with HIV, HCV, or HBV should be stored in separate HIV-, HCV-, or HBV-designated cryostorage tanks owing to the theoretical risk of transmission” (Penzias et al., 2020a). | ||||
• | ISAR recommends: “It is important to understand that while dealing with infectious biological material, cross-contamination via liquid nitrogen needs to be reduced. Separate cryo tanks for such samples and embryos should be maintained (Malhotra et al., 2021). |
ESHRE guidelines state: Safety issues have been raised regarding direct contact of the biological material with the LN2; however, at this point closed devices cannot be favored over open devices. Laboratories should make decisions based upon their results, risk analysis and regulations in place. Specimens from sero-positive patients should be stored in high-security closed devices.
Guideline: Potentially infectious oocytes and embryos may be stored in separate cryotanks if available, but it is recommended that semen samples from potentially infectious individuals be stored in dedicated cryotanks.
In a LRS the decision to not offer storage of infected semen may be taken because of the requirement to have a separate cryostorage tank.
Safe handling of liquid nitrogen
Laboratory personnel should wear protective safety goggles, insulated gloves, and closed shoes when handling LN2. Liquid nitrogen is a colorless, odorless liquid with a boiling point of −196∘C and is a hazardous liquid. At low temperatures nitrogen (in gaseous and vapour states) N2 is heavier than air. One liter of LN2 produces ∼700 liters of gas when LN2 vaporizes at room temperature. In the event of a leakage in a cryogenic storage tank or during handling of LN2, oxygen within the confined space will be quickly displaced by nitrogen without warning. Nitrogen gas is invisible – the cloudy vapour which appears when liquid nitrogen is exposed to air is condensed moisture, not the gas itself. Some of the main hazards associated with liquid nitrogen are asphyxiation, cryogenic burns, frostbite, and hypothermia (Tomlinson et al., 2012). Low oxygen tension alarms with supportive contingency plans are required in areas where refilling of cryostorage tanks with LN2 occur.
Risk of high CO2 in laboratories
High CO2 tension alarms with supportive contingency plans are required where CO2 is piped into the laboratory.
Recommendations for minimum standard of care
• | Prevention of transmission of infection between staff and patients requires consideration of risk of transmission of diseases such as hepatitis, HIV and syphilis and other sexually transmitted infections which may be carried by secretions and issues from the reproductive tract. Policy and procedures for reduction of risk are required. | ||||
• | Prevention of transmission of respiratory infection especially including COVID-19, influenza and tuberculosis needs specific risk assessment for the location of the facility and development of policy and procedures. | ||||
• | Prevention of transmission of infection between patients via their samples in storage is low risk for oocytes and embryos, but storage of semen with transmissible infection must be in separate storage tank and may not be offered in low resource settings where separate tanks are not affordable. High security sperm freezing straws can be used if separate tanks are not available but incur extra cost (Porcu et al., 2021). Reduction of risk of cross-contamination between patient samples whilst being handled by laboratory staff requires specific policy and procedures. | ||||
• | Avoidance of high CO2 is critical for staff safety and alarms and policy and procedures are required. |
TRACEABILITY (PATIENTS AND GAMETES)
Quick summary
• | Traceability systems are essential for the safe management of patients or reproductive cells (gametes). This session will discuss the minimum standards for essential safety management when performing Assisted Reproductive Technology (ART) in a limited-resource environment. The necessity and timing for implementing traceability as well as recommended tracking methods will be also discussed. | ||||
• | Keywords: Coding, training, documentation |
Background and specific objectives
Each stage of ART should consider the potential for errors in the following steps, which are the most critical: (1) incorrect identification of the patient, (2) improper specimen labeling, (3) oocyte retrieval, (4) sperm collection and preparation, (5) incorrect mixing of sperm and oocytes or incorrect sperm injection into the oocyte, (6) improper transfer of gametes or embryos between tubes/dishes, and (7) improper embryo transfer. Additionally, the following procedures should be considered as potential sources of errors:
(1) Cryopreserving the wrong gamete or embryo, (2) removing the wrong gamete or embryo from cryotanks (3) discarding the wrong gamete or embryo, and (4) transferring the wrong gamete or embryo.
Identification and traceability of each patient and biomaterial derived from the patient are critical in ART. The laboratories for ART should establish an accurate tracking system to identify each step uniquely and characteristically according to established protocols (Malhotra et al., 2021).
Evidence
This guideline is based on established international guidelines and regulations from professional organizations such as ASRM, ESHRE, HFEA, and India-ISAR, as well as related publications and the ASPIRE expert consensus.
Recommendations for minimum standard of care
Identification and traceability of each patient and biomaterials from the patient, such as gametes, are critical in the ART procedure. The laboratories for ART should establish an accurate traceability system to uniquely identify and characterize each step according to established protocols.
Establishment of procedures
The laboratory director is responsible for determining the proper tracking system, and appropriate identification systems must ensure that the patient (or donor) and information about biological materials from the patient or donor are constantly identified. The use of 3 unique identification markers is advised.
Identification training
It is strongly recommended that specific identification of patients and/or biological materials be verified by at least two trained and qualified staff. The handling of specimens should be conducted by staff who are trained in proper laboratory procedures for specimen (Malhotra et al., 2021).
Code assignment
Patient/Couple-specific unique identification code must be provided to the laboratory prior to the start of the ART procedure. This code should be easily and clearly accessible for patient consent forms, clinical data, serological results for patient ART procedures, and any revisions from the attending doctor. A patient-specific unique identification code must be assigned to each treatment cycle. For gamete or embryo collection from non-partner donors, specific coding may be required in certain countries (Rebecca et al., 2021).
Treatment steps
Patient identification must be verified at all critical steps of the ART procedure using the patient’s photo, name, date of birth and unique patient identification code. The patient is responsible for providing the necessary documented proofs (Rienzi et al., 2017).
• | All devices containing biological materials should be clearly and permanently marked with the three unique identification markers and the date of treatment. | ||||
• | Biological materials from different patients should not be processed simultaneously in the same work area. | ||||
• | Incubators and cryopreservation systems should consist of easily accessible and clearly identifiable to biological materials. | ||||
• | Patient identity should be verified and double-witnessed before all ART procedures, especially egg retrieval, semen collection, insemination, intracytoplasmic sperm injection (ICSI), cryopreservation, and embryo transfer. Double-checking by a second staff member is essential (e.g., embryo transfer or transfer from the cryo-freezing container). |
Recommendations in regular practice
The introduction of a barcode label system or a Radio-Frequency Identification (RFID) based technology system could be an alternative to prevent potential errors and would be appropriate to verify every step in ART. However, these systems are expensive and may not be used in LRS.
Genetic testing
All cells and embryos for genetic testing must be handled individually, carefully identified, labeled, and tracked throughout the entire procedure. Double-checking of patient and embryo identification should be performed at every step (Rebecca et al., 2021).
Overseas transfer
The transport of reproductive cells and tissues requires confirmation of the biological material and its suitability for clinical application. Wherever applicable, the identity of the sending and receiving organizations must be confirmed and verified. Each organization must verify the identity and attached specimen documentation, and match the patient’s records.
Overall recommended traceability steps (Rienzi et al., 2017)
Retention of documentation
The date and time of each procedure, the identity of personnel and second staff (or observer) should be documented throughout the ART procedure, and should be retained for a period specified by national legislation or governing, licensing and accrediting bodies. The identity of all clinicians and staff handling specimens at each step-in procedure should be documented and traceable.
TRACEABILITY (CONSUMABLES AND MEDIA)
Quick summary
• | This section provides minimum standards for the management of consumables and media in low resource settings in assisted reproductive technology. The guidelines cover traceability systems, documented procedures for managing consumables and media, specifications for consumables and media, shipment and storage, and alternative requirements for low resource settings. | ||||
• | Key words: Traceability, consumables, and media management. |
Background and specific objectives
Traceability of consumables and media in an IVF laboratory refers to the ability to track and document the use, movement, and storage of the materials and supplies used in the laboratory. The implementation of traceability systems in an IVF laboratory can have both advantages and disadvantages. On the one hand, traceability systems can improve patient safety by reducing the risk of contamination, misidentification, mix-ups, and other errors. They can also help to ensure quality control and regulatory compliance and improve the efficiency of the IVF procedure by streamlining processes. On the other hand, setting up and maintaining traceability systems can be time-consuming and costly, and may require additional staff training and infrastructure. In addition, the use of electronic systems may pose security and privacy risks, such as the possibility of data breaches or unauthorized access to patient information. It is important for IVF laboratories to carefully weigh the pros and cons of implementing traceability systems and to design a system that meets their specific needs and constraints.
Although the latest traceability technologies should be taken into consideration when establishing a modern IVF laboratory, minimum standards are necessary for low-volume clinics or resource-limited settings. This section aims to review various techniques for managing consumables and media and establish a minimum standard for their management in resource-constrained environments.
Evidence
The evidence for the recommendations in this guideline is based on established international guidelines and directives from professional organizations (ASRM, ESHRE, RTAC, ISAR and HFEA), and ASPIRE expert consensus.
Recommendations for minimum standard of care
In regulated IVF labs, traceability and accurate documentation of inventory items is crucial for regulatory compliance reporting and efficiency in laboratory operations. Two categories of solutions for inventory management in IVF labs exist: manual and digital. Manual entry into paper or spreadsheets is the oldest and most common method of tracking consumables, but it is time-consuming and prone to human error. Digital systems such as barcode labels and RFID offer superior accuracy and several benefits compared to cumbersome manual systems.
In low resource settings, implementing a traceability system for consumables and media can be challenging due to limited financial and technical resources. However, there are several recommendations that can help IVF labs in low resource settings to establish effective traceability systems :
• | Simplify the system: Choose a traceability system (manual or electronic) that is simple and easy to use, with minimal technical requirements. This will help to minimize the cost of implementation and training. | ||||
• | Utilize existing resources: If possible, utilize existing resources, such as smartphones or computers, to minimize the cost of equipment. | ||||
• | Prioritize critical items: Focus on traceability for critical items, such as culture media, culture dishes that have a direct impact on gametes and embryos. | ||||
• | Staff training: Ensure that staff members receive adequate training on the traceability system, including its use and maintenance. This will help to ensure the system is used effectively and maintained properly. | ||||
• | Collaborate with stakeholders: Collaborate with stakeholders, such as suppliers and regulatory agencies, to establish and maintain the traceability system. | ||||
• | The traceability system should be comprehensive and cover all consumables and media that could potentially affect the quality or safety of gametes and embryos (HFEA Code of practice, 2021). This includes having a documented procedure for managing these items, including selecting, procuring, forecasting, dispensing, monitoring the expiry date and disposal (Ho Chi, 2020). | ||||
• | An appropriate stock management system should be in place, including the batch number, date of entry and expiration date of consumables and media (ESHRE, 2015). | ||||
• | Specifying the quality and requirements for consumables and media: All consumables and media should be tested by manufacturers for quality using appropriate assays whenever possible (ESHRE, 2015) sterile single-use disposable consumables should be used, and all items should be used prior to their expiry date. The size of the bottles and other packaging should be appropriate to minimize openings and time between first and last use. Additionally, it is recommended to verify the pH of any new lot of culture media falls within the laboratory’s defined limits before use (ASRM, 2022). | ||||
• | Ensuring proper shipment and storage: During shipment, the correct temperature should be verified, and the packaging integrity and appropriate delivery conditions should be checked. Cold storage areas or refrigerators should be equipped with a remote temperature alarm system to guarantee appropriate storage conditions (Ho Chi, 2020). | ||||
• | Lastly, risk assessments should be performed to ensure all consumables and media are easily identified and prevent any potential misuse (ESHRE, 2015). |
BENCHMARKING
Quick summary/at a glance
• | Defining competency values for embryologists is crucial for ensuring the quality of their work, protecting patient safety, and maintaining the credibility of the field. | ||||
• | Keywords: KPIs, competency values, embryo development rate |
Background and specific objectives
In the context of in vitro fertilization (IVF), benchmarking refers to the process of comparing the performance of a fertility clinic with the performance of other clinics, in terms of their success rates in treating infertility. This comparison is typically made using standard metrics, such as the clinical pregnancy rate per embryo transfer or the live birth rate per cycle started. The purpose of benchmarking is to provide patients with information about the relative success of different clinics, which can help them make informed decisions about where to seek treatment. Competency values provide a set of defined standards for embryologists to ensure the quality of their work and patient safety. Defining competency values helps to :
• | Ensure that embryologists have the necessary knowledge, skills, and abilities to perform their work effectively and efficiently. | ||||
• | Provide a benchmark for assessment of individual embryologists, helping to identify areas for improvement and provide a framework for continuing professional development. | ||||
• | Enhance the credibility and reputation of the field of embryology and increase public confidence in the services provided. | ||||
• | Ensure that the standards of care are consistent across different clinics and facilities, improving patient outcomes and reducing the risk of error. |
Evidence
The Vienna Consensus Report is a set of guidelines for in vitro fertilization (IVF) laboratories that were developed by a group of experts in the field of reproductive medicine. The report is intended to promote consistent and high standards of care in IVF laboratories and to support the ongoing development of the field. The American Society for Reproductive Medicine (ASRM) also provides recommendations for benchmarking in vitro fertilization (IVF) laboratories (ASRM, 2022) these recommendations are intended to provide a standard of care for IVF clinics and laboratories, and to help improve the quality and consistency of IVF services. They recommend that IVF laboratories adopt best practices for benchmarking, including accreditation, quality control, laboratory design and organization, personnel qualifications, and access to the latest equipment and supplies. These recommendations are intended to support the ongoing development of the field and to improve the quality and consistency of IVF services.
The consensus provides recommendations on various aspects of IVF, including :
• | The timing and frequency of ovarian stimulation. | ||||
• | The criteria for selecting embryos for transfer. | ||||
• | The use of pre-implantation genetic testing (PGT). | ||||
• | The optimal number of embryos to transfer. | ||||
• | The approach to cryopreservation (freezing) of embryos and eggs. |
The Vienna Consensus aims to promote evidence-based, patient-centred, and safe IVF practices. The guidelines also emphasize the importance of considering individual patient factors and balancing the benefits and risks of treatment (ESHRE, 2017).
The ASRM recommends that IVF laboratories implement the following best practices for benchmarking :
• | Accreditation: IVF laboratories should be accredited by a recognized accrediting organization, such as the College of American Pathologists (CAP) or the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) or recognized by local governing body. | ||||
• | Quality control: IVF laboratories should have systems in place for quality control and quality assurance, including regular monitoring of laboratory performance, proficiency testing, and ongoing staff training. | ||||
• | Laboratory design and organization: IVF laboratories should be designed and organized to meet the specific needs of the laboratory and the patients it serves, with a focus on patient safety, comfort, and confidentiality. | ||||
• | Personnel qualifications: IVF laboratories should have personnel who are qualified and trained in reproductive technology and who have a working knowledge of the relevant standards and guidelines. | ||||
• | Equipment and supplies: IVF laboratories should have access to the latest equipment and supplies, and should maintain them in good working order. |
Recommendations for benchmarking in minimum standard of care
Defining a reference population is crucial while calculating these KPIs.
The suggested reference population is a female patients years old, with own fresh eggs, ejaculated sperm (fresh or frozen), any insemination method and no preimplantation genetic diagnosis (PGT). If applicable: stratified by ovarian response [poor (PR), normal (NR), and High response (HR)]. Competency and Benchmark values are generally used for Normal to High responders. Competency values are minimum expected outcomes whereas benchmark values are the best practice goals to achieve the KPIs (Maribor Consensus, 2021). Several factors can compromise these rates and segregating a pool of patients that the clinic believes have a good prognosis can be a good starting point to calculate these benchmarks.
Andrology laboratory:
• | Sperm motility post-preparation The percentage of motile spermatozoa in sperm preparation for insemination should be extremely high, and poor readings would suggest issues with the sperm preparation process. Competence reference levels are 90% and benchmark values are 95%. |
Embryology laboratory: (ESHRE, 2017)
i. | Normal IVF fertilization rate As it depends on efficient gamete handling and culture, the IVF fertilization rate is a key indicator of laboratory efficiency and a reflection of the entire IVF system. Competency is set at 60%, and benchmark is set at 75%. | ||||||||||||||||
ii. | Abnormal fertilization rate IVF Polyspermy Rate is essential to provide the data to evaluate any observed changes in the usual fertilization rate. A 6% polyspermy rate was generally agreed upon. The percentage of inseminated oocytes on Day 1 (16–18h post-insemination) that have one pronucleus is known as the 1PN Rate After IVF, or ICSI. It should be low under normal circumstances since it can serve as a signal of a problem with gamete handling or culture conditions. The general agreement was that the 1PN rate for IVF should be about 5%. | ||||||||||||||||
iii. | ICSI fertilization rate The number of fertilized oocytes on Day 1 (presence of 2PN and 2PB measured at 16–18 hrs post-injection) as a function of all MII oocytes injected is the ICSI Normal Fertilization Rate KPI. This KPI excludes in vitro developed oocytes as well as thawed/warmed oocytes (this was addressed in the cryopreservation consensus), and only includes ejaculated spermatozoa (fresh or frozen), as results may be lower with surgically recovered spermatozoa (Alpha Scientists in Reproductive Medicine, 2012). The expert group agreed on the following reference values: ; . | ||||||||||||||||
iv. | ICSI damage rate The percentage of oocytes that are harmed during ICSI injection or have deteriorated by the time of fertilization measurement on Day 1 is known as the ICSI Damage Rate. Competence is 10%; benchmark is 5%; these are the reference standards for ICSI damage rate. | ||||||||||||||||
v. | Failed fertilization rate The percentage of IVF cycles (excluding ICSI cycles) with no signs of fertilization (i.e., 0 oocytes with 2PN) on Day 1 (17 1h post-insemination) is known as the failed fertilization rate (IVF cycles). It can serve as a sign of a problem with sperm processing, spermatozoa production, or gamete quality (sperm function, oocyte activation, or gamete receptors). It was agreed upon that the IVF failed fertilization rate for stimulated cycles should be less than 5% based on the results of the Alpha survey and the numbers advised by the Association of Clinical Embryologists (Hughes, 2012). Total ICSI failed fertilization rate: incidence is rare and thus needs to be reported by exception. | ||||||||||||||||
vi. | Cleavage rate The percentage of zygotes that cleave to become embryos on Day 2 (44 1h post-insemination) is the cleavage rate KPI (Balaban et al., 2011). A low cleavage rate may be a sign that an external factor has affected the culture system since it shows whether the system can sustain the cleavage of fertilized oocytes (i.e., when cellular division occurs) and embryo viability. ; are the reference levels. | ||||||||||||||||
vii. | Blastocyst development rate The proportion of blastocysts found at 114–118 after insemination as a function of the total number of normally fertilized oocytes is known as the KPI blastocyst development rate. Competency is set at 40%, while benchmark is set at 60% (Day 5). An additional 10–15% blastocysts developing by 140+/−2h post-insemination might be a potential rate to keep in mind. | ||||||||||||||||
viii. | Good Quality Blastocyst Development Rate This indicator provides an estimation of the culture system’s capacity to support the development of high-grade blastocysts from fertilized oocytes, including an indication of embryo viability and the production of ICM, TE, and a blastocoele cavity. Competency values are set at 30%, while benchmark values are set at 40%. High-quality blastocysts were defined as having a grade of at least 3BB. | ||||||||||||||||
ix. | Implantation rate for cleavage stage and Blastocyst Stage Implantation rate is defined as the number of gestational sacs observed divided by the number of embryos (cleavage-stage or blastocysts) transferred. An overall low implantation rate is a critical indicator of a systemic issue since it gives a snapshot of the laboratory’s entire performance. Reference values for implantation rates :
| ||||||||||||||||
x. | Live birth rate The general conclusion was that there are just too many other factors at play to justify using LBR as a KPI. | ||||||||||||||||
xi. | Cryosurvival rate Despite certain device variations, it is currently reasonable to anticipate that competence for blastocyst cryosurvival with vitrification will be around 90% and benchmark should be 95%. | ||||||||||||||||
xii. | Successful Biopsy rate The percentage of samples that are successfully biopsied and tubed/fixed and where DNA is found, is known as the KPI successful biopsy rate. It is a gauge of the embryologists’ capacity to transfer the biopsied samples to test tubes, as demonstrated by successful DNA amplification. The reference values were competency 90% and benchmark 95%. | ||||||||||||||||
xiii. | Implantation Rate of Biopsied Embryos: It is safe to assume that the implantation rate for biopsied blastocysts would be equal if not higher than the reported general implantation rates. |
Clinical recommendations (ESHRE, 2017; Maribor Consensus, 2021)
i. | Number of oocytes Recovered: According to the ESHRE Special Interest Group of Embryology, the oocyte retrieval rate (ORR), also known as the percentage of recovered oocytes (in stimulated cycles), is calculated as the ratio of oocytes retrieved during OPU to follicles on the trigger day. While it is a helpful reference indication for the laboratory, ORR is a measure of the effectiveness of patient monitoring and may be modified by the time of the trigger. Expected range –80–95% of follicles measured. | ||||
ii. | Maturation Rate at ICSI: The Vienna consensus classified the ratio of mature (MII) oocytes at ICSI over the number of cumulus-oocyte complexes recovered as a reference indication and defined it as the number of mature (MII) oocytes at ICSI over the number of cumulus-oocyte complexes (ESIG, 2017) Expected Range 75–90% at h post-trigger. | ||||
iii. | Cycle cancellation rate (before oocyte pick-up (OPU)) (%CCR): Cycle cancellation following OPU may be caused by unsuccessful fertilization, inadequate embryo development, or no oocytes being found after oocyte extraction (see also the discussion of the rate of no oocytes recovered or the occurrence of empty follicle syndrome). Cycle termination before OPU can be ascribed to inadequate ovarian stimulation response, early ovulation, or drug administration mistakes. It was decided that cycle cancellation prior to OPU was an important factor to consider when evaluating ovarian stimulation performance. | ||||
iv. | Rate of cycles with Moderate to severe OHSS Based on existing studies (The Maribor Consensus, 2021), when GnRH agonists are used to stimulate the ovaries, the expected incidence of moderate/severe OHSS is 6.4% in the normal population and 10.6% in patients with PCOS. When GnRH antagonists are used, the expected incidence of moderate/severe OHSS is 2.9% in the normal population and 2.1% in patients with PCOS. Competency Value Antagonist: 1.5% Benchmark: 0.5% Competency Value Agonist: 2.5%, Benchmark: 1% | ||||
v. | Complication after OPU rate: OPU can lead to a variety of complications, such as bleeding (severe vaginal, intra-abdominal, or intraperitoneal haemorrhage), infection, excruciating pain, or damage to the pelvic tissues. With a reported frequency ranging from 0.01% to 18.8%, vaginal bleeding appears to be the most typical OPU complication. A disparity in the definition of vaginal bleeding may be to blame for this large discrepancy. A more severe OPU complication, peritoneal haemorrhage, has a documented incidence of 0.05% to 0.35%. (Murray and Kovacs, in press) With an incidence of 0.01–0.1% pelvic organ damage is a rather uncommon consequence, but pelvic infections vary from 0.04% to 0.77%. According to reports, between 0.06 and 0.7% of patients have severe discomfort that necessitates hospitalization | ||||
vi. | Multiple Pregnancy Rate: The 2016 EIM data collection reporting reveals significant variations in MPRs amongst European nations, ranging from 1.1% to 35.7% (Calhaz-Jorge et al., 2020). To improve ART safety and efficacy, it has been suggested reducing the frequency of numerous pregnancies or births.There is a need for a consensus on acceptable MPR for the region, a possible recommendation could be (Hammarberg et al., 2018). |
Recommendations for benchmarking for low volume clinic or low resource setting
Owing to the differences in staffing and infrastructure it is recommended that a Low resource or low volume centre document the following benchmarks. A low volume clinic should at least document these benchmarks in order to ensure standards of care are maintained.
Implementation, Monitoring and Quality Assurance (Fabozzi, Gemma, et al., 2020)
The control chart is one of the most popular tools employed in this process. The Shewhart chart or Levey-Jennings quality control chart is the most often used diagram. In a nutshell, a control chart should show the “control mean” for the previous six months, upper and lower “warning limits” set at 2 and 3 standard deviations, respectively. An indicator should, in theory, oscillate between the lower and higher control limits according to physiological fluctuation brought on by patient variability. There are four possible outcomes, though :
• | When an indicator passes the low control limit, it must be resolved immediately; | ||||
• | When it crosses the low warning limit, it must also be resolved immediately. | ||||
• | When the indicator reaches the low warning level, action is needed to establish if a Problem will ultimately exist; and an immediate action is needed to identify the issue and seek its resolution. | ||||
• | When the indicator consistently goes below the warning limit without reaching the control limit three times, necessitating a response to ascertain whether a potential issue could be developing. |
