External quality assessment performance in ten countries: an IFCC global laboratory quality project

Area of Science:

• Clinical Chemistry
• Laboratory Medicine
• Global Health

Background:

• External Quality Assessment (EQA) is crucial for maintaining laboratory quality.
• Cultural and environmental factors can impact EQA performance.
• Standardized EQA implementation is vital for reliable patient diagnostics globally.

Purpose of the Study:

• To evaluate the validity of EQA laboratory results in diverse global settings.
• To identify specific areas needing improvement in EQA programs.
• To assess the impact of logistical challenges on EQA participation and success.

Main Methods:

• A 2-year study (2022-2023) involving 100 laboratories in ten countries.
• Provision of EQA materials, software, and training by a commercial vendor.
• Monthly analysis of EQA results, including submission rates, acceptability, and analyte performance.

Main Results:

• Six out of ten countries achieved >90% acceptable results.
• Four countries demonstrated performance below acceptable standards, requiring intervention.
• Logistical issues, such as customs delays, affected timely EQA material receipt and submission.

Conclusions:

• Participating laboratories reported satisfaction with EQA services and training.
• Addressing specimen reception issues and optimizing dispatch schedules are recommended.
• Targeted, long-term assistance is necessary for four countries to enhance EQA performance and ensure diagnostic accuracy.
