What is External Quality Assessment?
External quality assessment (EQA), or external quality assessment schemes (EQAS), is an examination of the effectiveness of a laboratory's quality management system. The term external refers to the fact that the laboratory's results are assessed by a third party. This process is typically used in medical laboratories.
Background and Importance
Quality management systems are crucial in medical laboratories to ensure that test results are accurate and reliable. External quality assessment provides an independent evaluation of a laboratory's performance, helping to identify areas for improvement and maintain high standards. This is particularly important in healthcare, where accurate test results can have a significant impact on patient treatment and outcomes.
Key Facts
- External quality assessment is an examination of a laboratory's quality management system.
- The term external refers to the fact that the laboratory's results are assessed by a third party.
- Proficiency testing is a common EQA process, where an organization sends samples to a group of different laboratories and results are compared among the group.
- Retesting of the same sample by different laboratories and on-site visits to evaluate laboratory processes may also be part of an EQA scheme.
History
The exact date of the introduction of external quality assessment is not specified in the source. However, it is clear that this process has been used in medical laboratories for a significant amount of time.
Examples
External quality assessment is used in various medical laboratories around the world. For example, in the United States, the College of American Pathologists (CAP) offers EQAS programs for medical laboratories. These programs provide a framework for laboratories to assess their performance and improve their quality management systems.
