Análisis Lean Six sigma de la fase preanalítica del proceso de Laboratorio Clínico del Hospital del IESS Ambato

Abstract

At the clinical laboratory level, it is essential to avoid the generation of errors, since they affect the patient's diagnosis, that is why the research developed a Lean Six Sigma analysis to analyze the current situation of the preanalytical phase of the clinical laboratory process at the IESS Ambato Hospital. considering the quantity of waste generated by defects as an indicator of the quality offered by the institution. In the development of the Lean Six Sigma analysis for the pre-analytical phase, the variability of their processes was determined through the DMAIC methodology. where each of its phases was subjected to statistical tools and not statistics in a span of 20 days on 395 biological samples. In the determination of process waste, the five why tool was used and the AMEF diagram was used to analyze the risk of occurrence. The critical processes are in the reception and extraction area of the preanalytical phase, which has metrics of 2.91 and 4.1 sigma respectively, being an indicator that implies the generation of 6583 errors for every million biological samples analyzed. These generate financial losses to the IESS Hospital in Ambato of 94.90 dollars for every thousand units processed. Finally, with the improvement proposals, the reduction of 85% of the errors produced in the reception area is expected, and 95% in the extraction area, improving the quality of the service.
