Kennzahlen und Benchmarking im Krankenhauslabor

Benchmarking is a systematic and continuous process to compare products, services, and processes - in quantitative and qualitative aspects. Benchmarking in labo ratory medicine departments of hospitals is a fre- quently used but only poorly standardized method. Sophis- ticated procedures for data collection are necessary due to large heterogeneity and complexity of activities performed in laboratory medicine with regard to type of testing, response times, availability and amount of different resources needed for single analysis and reporting. These prerequisites are difficult to fulfill. In internal benchmark- ing projects - i.e., monitoring of productivity, costs, and revenues within one laboratory over an extended period of time - the current tools for data collection are generally suited for use. In external benchmarking, however, several pitfalls may obscure the results. Broadly, external bench- marking projects compare only partial processes with sufficient validity. Differences in benchmarking have to be controlled for improvements of data collection and for changes of surrounding conditions outside the laboratory. This review lists different approaches for benchmarking projects in laboratory medicine departments and describes their strengths and weaknesses.
