Sažetak

Introduction: Laboratories minimize risks through quality control but analytical errors still occur. Risk management can improve the quality of
processes and increase patient safety. This study aims to use the failure mode and effect analysis (FMEA) to assess the analytical performance and
measure the effectiveness of the risk mitigation actions implemented.
Materials and methods: The measurands to be included in the study were selected based on the measurement errors obtained by participating
in an External Quality Assessment (EQA) Scheme. These EQA results were used to perform an FMEA of the year 2017, providing a risk priority number
that was converted into a Sigma value (σFMEA). A root-cause analysis was done when σFMEA was lower than 3. Once the causes were determined,
corrective measures were implemented. An FMEA of 2018 was carried out to verify the effectiveness of the actions taken.
Results: The FMEA of 2017 showed that alkaline phosphatase (ALP) and sodium (Na) presented a σFMEA of less than 3. The FMEA of 2018 revealed
that none of the measurands presented a σFMEA below 3 and that σFMEA for ALP and Na had increased.
Conclusions: Failure mode and effect analysis is a useful tool to assess the analytical performance, solve problems and evaluate the effectiveness of
the actions taken. Moreover, the proposed methodology allows to standardize the scoring of the scales, as well as the evaluation and prioritization
of risks.
