[Evaluation of an internal guideline for the diagnostics of deep vein thrombosis].

Background And Purpose: In line with the application of evidence-based medicine as part of the day-to-day clinical practice of a community hospital internal guidelines concerning relevant diagnostic or therapeutic problems were developed. The authors retrospectively compared all data of patients with the tentative diagnosis of deep vein thrombosis (DVT), who underwent further diagnostics before and after implementation of an internally developed guideline for the diagnostics of DVT. The aim was to evaluate if the internal guideline was applied by the doctors in the daily routine and if the implementation led to a change and rationalization of the diagnostic process, in particular with regard to reducing invasive examinations.
