[Cost-benefit analysis of cranial computed tomography in mild traumatic brain injury--appropriate depiction within the G-DRG system?].

BACKGROUND
The treatment of patients with mild head injury is related to a continuous lack of finances. The current investigation summarises radiological costs of patients from a level I trauma centre and discusses the indication for CT scanning within the G-DRG system.


MATERIAL AND METHODS
The study includes all patients who underwent a CCT scan in 2011. Diagnosis, length of stay and cost data were recorded for every patient. Finally, frequent diagnosis groups were summarised to clusters (Basis-DRG/MDC 21A).


RESULTS
A total of 380 patients was treated. Within the largest group (G-DRG B80Z) the costs for a CCT already took up one quarter of the total proceedings. In combination with the high cost for monitoring patients with mild head injuries this causes an ongoing lack of finances.


CONCLUSION
In spite of the often necessary CCT investigation in mild head injuries, the earnings do not cover the costs of the patients. To improve the situation clear guidelines for CCT scanning should be provided and the reimbursement in particular in the diagnosis group of the G-DRG B80Z has to be improved.
