Resource utilization and costs of stroke unit care in Germany

Abstract Objectives Stroke imposes a considerable economic burden on the individual and society. Recently, the concept of an integrated stroke unit has been established in several countries to improve the outcome of patients. This study evaluates the costs of acute care of the different cerebrovascular insults in a stroke unit. Methods The study population included 340 patients who were consecutively admitted to the Department of Neurology, Philipps University Marburg, with the diagnosis of stroke or transient ischemic attack (TIA) between January 1 and June 30, 2000. Clinical status and course were evaluated by using the Barthel index and the modified Rankin scale. Employing a "bottom-up" approach, we calculated the costs from the perspective of the hospital and the third-party payer using data from provider departments and other published sources. Results Inpatient costs were €3020 (US$3290) for TIA, €3480 (US$3790) for ischemic stroke (IS), and €5080 (US-$5540) for intracerebral hemorrhage (ICH) and differed significantly among these subgroups ( P P > .05). Approximately 30% of the hospital costs are due to physician charges and care. Imaging amounted to 10% and lab investigations to 14% of total costs, independent of the diagnosis. Postacute treatment, including inpatient rehabilitation, cost €9880 per patient. Across all diagnostic groups, a mean clinical improvement was observed at time of discharge. Conclusions Care of patients with cerebrovascular events in a stroke unit causes a high demand of resources and has a considerable impact on health-care expenditure. Therefore, investigations comparing the stroke unit concept with other strategies in stroke care are necessary to evaluate the stroke unit concept for a rational use of available resources in patients with cerebrovascular events.
