“…In the first step, products (e.g., items, cases) have to be defined so that, in the second step, prices for these products can be determined or negotiated [3]. Products can either be defined as individual medical procedures performed (e.g., the DBC system in the Netherlands with its 29,000 items), as groups of medical procedures (e.g., the procedure-oriented system in Poland with its 1,400 items), or as a combination of clinical, demographic, and resource consumption data (i.e., as is usually applied in DRG-related patient classification systems) [23]. The second step involves calculating, setting, or negotiating per-product prices.…”
