title: [Examples and proposed solutions for methodological problems in hospital appropriateness assessment].
abstract: Inappropriate hospital care has become a recurring theme since the publication of the results of the model project on the appropriateness of hospital care (Section 275 a SGB V) by the medical service of the National Associations of Health Insurers (MDS) in Spring 1997. Nationwide, an increased number of appropriateness assessments have since been conducted by the medical service of the health insurers (MDK). The basis for an objective assessment of the appropriateness of hospital care is a diligent, comprehensive, and methodologically valid examination of the actual situation. At first, it was unknown to what extent current methods in Germany conformed to international scientific standards in Epidemiology, Biometry, and Health Services Research. Following a thorough scientific examination of several typical methodologies, it became clear that current methods are insufficient, and hence do not allow valid conclusions regarding inappropriate hospital admissions or hospital days. This statement does not deny that inappropriate hospital use is very likely, but our current assessment tools do not permit further conclusions to be drawn. The purpose of this article is to identify typical mistakes in the fundamental aspects of a valid assessment based on selected examples. Proposals are made regarding methodology and the presentation of results that follow from this critical examination.
