AbstractIn order to improve the quality of medical care, minimum volumes for services were set. Hospitals are only permitted to continue to provide these services and settle accounts with the health insurance companies if they are able to achieve these minimum annual volumes. This study is based on service data of the year 2002 from 88 neighboring hospitals of the hospital association Cologne, Bonn and region. In the study, the influence of these regulations on the provision of health care services in cardiology were examined. The cases were grouped according to the different examined services, followed by an analysis of the number of cases for each hospital in comparison to four fictitious minimum quantity models. When the hospital's volume remained below the minimum quantity, these cases were assigned to the nearest hospital still able to provide the service. For the services coronary angiography, PTCA, AICD implantation, EPS and ablation, only marginal case redistributions were determined. Depending on the minimum quantity, service concentrations are only expected for pacemaker implantations. Due to the increasing service concentration as a consequence of the DRG-payment system, a bureaucratic regulation of minimum volumes has become superfluous for most cardiological services. Instead of minimum volume regulations, recommendation of minimum volumes should be made in cardiological guidelines.
