Plan de mejora de calidad a la fase preanalítica mediante la metodología Seis Sigma en el Laboratorio Clínico Labclimed, Quito, 2021

Abstract

Abstract: Introduction: Within the processes of a laboratory is the preanalytical phase; It is considered the most critical because a greater number of errors can be made. Objectives:Determine the types of pre-analytical incidents and their frequency, analyze the quality indicators based on the Six Sigma methodology and develop a continuous improvement plan for the pre-analytical phase. Method: observational, descriptive and retrospective study; carried out in the Labclimed Laboratory, the information was obtained from the laboratory database corresponding to 2021. Results: 394 incidents were analyzed; the main preanalytical incident corresponds to: Erroneously identified requests (40.9%), Hemolyzed samples (25.6%), and Unidentified samples (17.8%). According to Six Sigma performance, the lowest value was obtained by Erroneously identified requests (4.1), Hemolyzed samples (4.2) and Unidentified samples (4.4); Based on these results, an improvement plan for the preanalytical phase was proposed. Conclusions: The incidents that occurred in the pre-analytical phase can be prevented, theharmonization of quality standards, the optimization of resources and processes; andthe cooperation between the laboratory and the sampling centers can significantly improve the pre-analytical phase.
