Impacto de la implementación de un sistema documental en el aseguramiento de la calidad en un laboratorio de análisis clínicos de un hospital público. Acta bioquím. clín. latinoam.

The purpose of this study was to analyze the impact of implementing a quality management system (QMS) in the performance of a clinical laboratory of Hospital Materno Provincial. Ten quality indexes (QI) have been designed; they were measured before and after the implementation of the document management system (DMS). For the "incorrect medical application" index, there was a reduction from 11.2% to 6% when the DMS was implemented. For the "diagnostic omission" index, the percentage decreased from 41.6% to 27.9% after the implementation. Five per cent of mistakes were found in the admission of the laboratory computer system in the baseline state and 3.9% of the mistakes were found after implementation of the system. Meanwhile, the "incorrect sent samples" index decreased from 3.1% to 1.9%. Fifty eight per cent of the analytes decreased the total error index and 80% of them increased the sigma value after the intervention. Sixty one per cent of the analytes decreased the uncertainty value, thus improving the performance of analytical methods. The percentage of critical values communicated to the physician before the 60 minutes increased from 20% to 54% after the implementation of the DMS, while the "reprint of reports" index decreased from 5.2% to 1.8%. The turn around time (TAT) decreased from 164 to 125 minutes. The implementation of a QMS, under the requirements of international standards, improved the knowledge and the functioning of different processes of the clinical laboratory. This has been evidenced by the decrease of mistakes in the pre-analytical, analytical and post-analytical phases.
