[10 years of Peer Reviewing: improving treatment by quality indicators from administrative data].

BACKGROUND AND OBJECTIVES
In-hospital mortality of myocardial infarction, heart failure and pneumonia within a private hospital chain were compared with the German average since 2000.


METHODS
Increased in-hospital mortalities based on diagnosis coding with ICD-10 benchmarked with German average values induced peer reviews in concern hospitals. From 2000 until 2010, peer reviews as performed by at least 2 peers compared retrospectively case management and treatment with best care, classified the treatment and discussed it with responsible physicians. The classification consisted of category 1 for improvement potential, category 2 for miscoding and category 3 for sufficient treatment. Based on the improvement potential an operational plan of treatment improvement for the single hospital was produced which was to be realized by this hospital and supported by concern activities for knowledge improvement.


RESULTS
In 2000, the indicators in-hospital mortality of myocardial infarction, heart failure and pneumonia of the hospital chain exceeded German average whereas in 2008 these values were lower (i. e. better) than German average. The peer reviews detected large improvement potentials in treatment processes and helped to improve them.


CONCLUSION
Peer reviews as triggered by quality indicators supported improvement of treatment and likely outcomes.
