[Cost analysis of hip and knee prostheses as the basis for cost-benefit evaluation].

INTRODUCTION

The diagnosis-related reimbursement for total hip- and knee arthroplasty is often interpreted as a claim for cost reduction and thus influences increasingly the surgeon's choice of treatment. With regard to further planned budget reductions the following questions arise: Remains quality payable? Where are cost savings possible?

PATIENTS AND METHODS

Prospective analysis of 21 patients with primary hip- and 26 with knee arthroplasties to identify all cost factors during the hospitalization period including the implantation technique and quality improvement measures.

RESULTS

Expenses of 18,763.26 DM for hip- and 18,649.40 DM for knee implants were covered by the diagnosis-related reimbursement. Compared to cemented implants, the average total costs of cementless prostheses were usually less expensive.

CONCLUSION

Although the current costs are covered, a further reduction of the diagnosis-related reimbursement may result in a loss of quality. The present cost analysis outlines a guideline for an individual calculation and assessment of possible saving effects.
