ABSTRACT
OBJECTIVES: To maximize participation in the international standardization effort, this recommendation aims to update the international guidance of the Working Group on Laboratory Errors and Patient Safety of the International Federation of Clinical Chemistry and Laboratory Medicine by identifying a limited and globally applicable panel of Essential Quality Indicators (QIs) focused on patient safety, clinical outcomes, and harmonization across medical laboratories.
METHODS: Through a consensus meeting, experts from multiple countries reviewed the IFCC Model of Quality Indicators (MQI) to identify high-priority indicators. Selection prioritized the probability of patient harm, ease of detection, and feasibility of data collection and implementation within national contexts.
RESULTS: Six essential QIs covering the total testing process were identified and ratified: (1) rate of misidentified requests (Pre-MisR) and misidentified samples (Pre-MisS); (2) rate of sample rejections (Pre-RejS); (3) rate of hemolysis detected either by automated hemolysis index (Pre-HemI) or visual inspection (Pre-HemV); (4) rate of unacceptable results in External Quality Assessment/Proficiency Testing (Intra-Unac); (5) turnaround time of cardiac troponin at the 90th percentile for the emergency room (Post-TnTAT, Post-TnTAT clin); and (6) rate of incorrect laboratory reports (Post-RectRep). Recommendations on calculation, reporting frequency, and integration into IFCC and national comparison programs are provided.
CONCLUSIONS: The proposed essential QI panel provides a standardized and feasible framework to support its integration into national comparison programs and the IFCC MQI platform. Its implementation will facilitate data consolidation, strengthen the development of national and global quality specifications, and contribute to continuous improvement in patient safety.
