Since 1 January 2004, inpatient treatment services in German hospitals have been reimbursed using a prospective payment method based on diagnosis-related groups (DRGs) rather than daily rates. The aim of the payment system reform was to decrease the length of inpatient stays and reduce overall healthcare expenditure, the latter of which had increased markedly during previous decades.The primary objective of our study was to analyse and describe the health-economic consequences of implementing a DRG-based system of prospective payment in Germany.A systematic search of the literature was performed on MEDLINE. Inclusion criteria were a focus on health economic variables from the German perspective and a publication date after 1 January 2004. The search was supplemented by a manual review of references, as well as internet-based hand search. The main health-economic conclusions were subsequently extracted from all of the included studies.A total of 19 quantitative and qualitative studies were included. There were substantial differences between them in terms of medical focus and hospital characteristics. The most common health-economic variables analysed were revenue generated by patient treatment, and length of inpatient stay. As expected, both variables showed a decreasing trend following the introduction of DRGs. The included studies also investigated the development of case numbers, the proportion of outpatient services provided, the number of diagnoses per case, and the homogeneity of case groups. For these variables, the studies showed a wide range of results.Similar to the experience with DRGs in many other countries, the introduction of DRGs in Germany has led to a reduction in the length of inpatient stay and a decrease in hospital revenues. The effects on other health-economic parameters are inconsistent. Additional studies in this area are needed. |
