[Postoperative complications in stapes surgery. An analysis of medical and economic aspects].

With the establishment of DRGs in the German hospital financing system, knowledge of therapy costs and the suitability of therapies for reservation planning and medical cost management becomes important. Stapes surgery and its postoperative treatment is relatively standardised. The timing of intervention can be planned and serious complications are rare. We carried out a retrospective evaluation of all stapedectomies performed in Bochum University ENT department over 1 year ( n=46). The course of treatment and differences in expenditure between standard and complicated cases were recorded. We used the official calculation model of the Deutsche Krankenhausgesellschaft and the homogeneneity of the investigated patient groups was evaluated statistically. A total of 6.52% of all patients had complications, mainly temporary inner ear hearing deficit and vertigo, resulting in additional therapy. The average cost of a stapedectomy was 964 EUR for regular cases. The costs if complications occurred ranged from 1,754 EUR to 3,504 EUR. Statistical evaluation showed a strong homogeneity in the group of patients without complications, especially for the costs of surgery. Stapedectomy is suitable for flat rates due to the standardisation of therapy and the homogeneity of the patients. The profitability depends on the future DRG-flat-rate. Stapedectomy surgery seems to be appropriate for resource and cost management. To avoid unfair future losses for the hospitals, a mechanism of compensation for very expensive medical complications should be developed.
