UnlabelledINTRODUCTION Based on the data of the Institut für das Entgeltsystem im Krankenhaus (InEK) cost and revenue data for deliveries in Germany can be compared. The InEK calculates the cost data for each individual diagnosis-related group (DRG) on the basis of those hospitals that deliver their individual cost data, so-called "Kalkulationshäuser". The InEK only publishes data for patients with standard lengths of stay. It does not deliver data for short- and long-stay patients. Beside these cost data, the InEK publishes the nationwide case volume for each DRG. Having a knowledge of the individual base rate (Landesbasisfallwert), which differs from province (Bundesland) to province and, in addition, the nationwide case weight for each DRG, the average revenues for deliveries in general, vaginal deliveries, and Cesarean sections can be calculated. These revenue data differ not only from province to province, but from hospital to hospital because of the individual hospital-specific base rates.Materials And MethodsThe average costs for a delivery in general, a vaginal delivery, and a Cesarean section were calculated on the basis of the DRG Report Browsers 2005/2007-2007/2009 published by the InEK. The costs for short- and long-stay patients were estimated on the basis of a scenario technique. The revenues were calculated on the basis of the published DRG catalogues, which supply individual case weights, and the county-wide base rate. Short- and long-stay revenues again had to be estimated by a scenario technique. In every DRG the cost data create the basis for the case weight two years later.ResultsIn relation to the average base rate over all provinces the 2005 costs are higher than the revenues in each province. Even in Rhineland-Palatinate, the county with the highest base rate, costs and revenues are at par. Only the declining costs from 2005-2007 balance the costs and revenues nationwide. But in provinces with low base rates the revenues stay lower than costs. These data demonstrate the pressure of rationalisation on German perinatal medicine and their hospitals. Cost and revenue comparisons with other countries are of lesser interest. Most countries have totally different systems for financing hospitals. In Germany, the published data show only the running costs financed by public and private health-care insurances. Infrastructure costs are financed by the government. In other countries not only the running costs but also the investment costs must be financed by running revenues too.© Georg Thieme Verlag KG Stuttgart · New York.
