Purpose: A cohort study was carried out to analyse quality indicators in the diagnosis and treatment of rectal carcinoma.
Methods: A total of 2,470 patients with rectal carcinoma treated between 1985 and 2007 at the Department of Surgery, University of Erlangen, were analysed and compared within four time intervals.
Results: Most of the indicators analysed from 2004 to 2007 fulfilled the defined target values. The indicators for process quality of surgical treatment and the surrogate indicators of outcome quality in surgery showed excellent results. Comparing this to previous data, it displays the new developments such as introduction of multimodal treatment for high-risk patients. While the rate of locoregional recurrences decreased, no significant improvement in survival was found.
Conclusions: Careful analysis of quality indicators is important for both quality management and comparison of treatment results. The progress in diagnosis and treatment requires a continuous update of definitions and target values.
