[Quality Assurance Using Administrative/Routine Data for Cholelithiasis - Changes Over Time and Current Status].Zentralbl Chir. 2019 Jun; 144(3):264-272.ZC
Quality assurance using administrative/routine data (QSR) is a relatively new measure to assess outcome quality. This approach is methodologically distinct from external quality assurance, as well as from quality assurance based upon registries. Since 2011, QSR for cholelithiasis within AOK patients has been overseen by the Scientific Institute of the AOK (WIdO). Following the introduction of an expert panel in 2013, numerous changes were put into place, whereby the indicator rates for transfusion/bleeding, various complications as well as the overall indicator were reduced. Interestingly, the risk adjusted quality differences between hospitals remained solid.
