Information systems as a quality management tool in clinical laboratories

Abstract

This article describes information systems as a quality management tool in clinical laboratories. The quality of laboratory analyses is of fundamental importance for health professionals in aiding appropriate diagnosis and treatment. Information systems allow the automation of internal quality management processes, using standard sample tests, Levey-Jennings charts and Westgard multirule analysis. This simplifies evaluation and interpretation of quality tests and reduces the possibility of human error. This study proposes the development of an information system with appropriate functions and costs for the automation of internal quality control in small and medium-sized clinical laboratories. To this end, it evaluates the functions and usability of two commercial software products designed for this purpose, identifying the positive features of each, so that these can be taken into account during the development of the proposed system. © 2007 IOP Publishing Ltd.
