[Hospital financing in in-patient psychiatry via DRG-based prospective payment--The Salzburg experience].

Hospital financing via case-related prospective payment sometimes is suspected to be responsible for accelerating the "revolving-door"-phenomenon in psychiatry. According to this reasoning, establishing diagnoses-related groups (DRGs) ruling a prospective payment system could not only reduce lengths of stay but could also simultaneously raise hospitalization and readmission rates. This study analyses the Austrian experience after the implementation of such a payment system, the "performance-oriented financing of hospitals" (leistungsorientierte Krankenanstalten-Finanzierung, LKF) in 1997. Time series analyses based on the complete hospital discharge statistics of the Salzburg province were used as methods. Results showed that neither length of stay, nor hospitalization or readmission rates in psychiatry have substansially changed or deviated from their long-term trends after implementation of the LKF system. Other medical disciplines have experienced statistically significant changes. The possibility to transfer these results to the German psychiatric health care system is discussed.
