[Evidence-based medicine in the real world--an experimental evaluation in a hospital care system].

: In Germany, effective tools for the implementation of evidence-based medicine (EbM) in the hospital setting have been rarely recorded. In the model project of the Park-Klinik Weissensee in Berlin, the so-called Park-Klinik EbM project, a multi-dimensional integrational approach is being put to the test. The Berlin hospital regards recommendations for actions based on EbM in the form of text modules (EbM bits of information) employed for discharge letters of the Department of Internal Medicine and locally tailored clinical practice guidelines as appropriate means for the implementation and application of EbM. Here we present conceptual developments and the first results of quantitative and qualitative evaluation. The benefits of EbM efforts are critically (positively) appraised. The dissemination and implementation of clinical practice guidelines into everyday evidence-based practice must still be improved, though. EbM bits of information are successful and effective instruments for both clinicians and general practitioners.
