CONTEXT: Germany and Switzerland have introduced diagnosis-related groups (DRGs) for hospital reimbursement. This scoping review aims to evaluate if empirical evidence exists on the effect of the DRG introduction. METHODS: Medline via PubMed, Embase (Elsevier), CINAHL, PsychINFO, and Psyndex were systematically screened for studies from 2003 onwards using keywords-DRG, prospective payment system, and lump sum-in English, German, and French. Abstracts were screened for alignment with our inclusion criteria and classified as editorial/commentary, review, or empirical study. The full-text extraction included data on country, study design, collected data, study population, specialty, comparison group, and outcome measures. RESULTS: Our literature search yielded 1944 references, of which 1405 references were included in the abstract screening after removal of duplicates. 135 articles were relevant to DRG, including 94 editorials/comments/reviews and 41 empirical articles from 36 different samples. The most frequently used outcome parameters were length of stay (12), reimbursement/cost (9), and case numbers (9). CONCLUSIONS: Only a minority of identified articles (30.4%; 41 of 135) presented empirical data. This indicates that discussion on the topic is not totally evidence-based. The only common trend was a decrease in length of stay.
