A

Key PIs (KPIs) are indicators deemed essential for evaluating…
objective measures for evaluating critical healthcare domains (patient safety, effectiveness, equity, patient-centeredness, timeliness and efficiency)
-represent an important element within the Quality Management System (QMS)

72
Q

Vienna consensus identified three different types of indicators:

A

Total 19 indicators categorized in three types:
Reference indicators (RIs)
related to the oocytes coming into the laboratory, and so were proxy indicators of the response to ovarian stimulation only (2RI):

2-Proportion of MII oocytes at ICSI
PIs
PIs were those for which data should be documented and stored, even if they are not routinely reported in a control chart. (5PIs)
KPIs.
were those related to the ‘core business’ of the ART laboratory.(12KPIs)

73
Q

Reference Indicator (RIs) for identifying performance of the ART laboratory.

75
Q

what are daily, monthly, and yearly Main Quality control parameters in the IVF laboratory?

A

Daily Quality Control:

  • Monitoring of Temperature of (incubators, hot stages, blocks), humidity and liquid nitrogen tank levels.
    -Equipment calibration such as incubators, microscopes,freezers and centrifuges is necessary to ensure accurate measurements and consistent performance.
    -Media quality control and availablity and expirey.
    -sterilization and infection control of cleaning walls, Floors, and stages.
    -Documentation and logbooks, laboratory procedures, observations, and outcomes are essential for quality control and traceability.

Monthly Quality Control:
-Biosurvival and embryo assys
-Consumable availability
-Expiration dates of consumables such as pipettes, culture dishes, and needles are important to maintain consistent results.
-Assessment of embryo development according to KPIs
-Quality control of cryopreservation procedures: Monitoring the viability and survival rates of frozen-thawed embryos and gametes helps ensure the effectiveness of cryopreservation techniques.

Yearly Quality Control:

-External quality assessment
-Review of laboratory protocols and SOPs
-Staff training and competency assessment

79
Q

The 5 Whys method

A

The 5 Whys method is a powerful and straightforward approach to root cause analysis that has been used in various industries worldwide. It focuses on asking why a problem happened and asking four more “whys” until you find the main cause
