[How does the German DRG system differentiate and reimburse vitreoretinal surgery in diabetic patients?].
The German DRG system (G-DRG system) is required to assign medical cases with similar costs correctly into a particular group, each case within the group receiving the same amount of reimbursement. At the same time the system should allow all-inclusive reimbursement, not necessarily reflecting the exact costs of each case. These opposite goals and the so far limited calculation basis raise the question of how the G-DRG system actually processes and reimburses empirically collected in-hospital treatment data. ⋯ The demographic and clinical G-DRG data of the included patients showed substantial cost-effective inhomogeneities. These inhomogeneities were not sufficiently considered for reimbursement based upon Z-DRG. Specialised departments with higher numbers of difficult cases may be discriminated. Wrong incentives may result in the selection of "low-risk cases".
