[An update of the German version of AEP (Appropriateness Evaluation Protocol): metric properties and practical experiences].
The development of a German version of the Appropriateness Evaluation Protocol (AEP) allows for the first time the evaluation of hospital admissions and bed days in Germany. The instrument is based on international experience and has been adopted in cooperation with acknowledged members of German surgical and medical societies. The AEP showed excellent reliability in general internal medicine as well as in surgery. The validity is comparable to international studies, although further research is necessary. Approximately 90% of surgical cases could be evaluated according to the criteria of the AEP; the remaining patients were evaluated using the "override option". The majority of inappropriate care is due to poor documentation in medical records and management deficiencies during inpatient care.
