The economization of inpatient care began when lump sum reimbursement was introduced into the hospital sector. Since then, total hip arthroplasty (THA) has experienced a rapid development in terms of annual procedures and the optimization of the clinical pathway. Therefore, it is obvious to highlight THA as one of the most common procedures in the German health care system. In this work, the two most common techniques for the fixation of THA are investigated with regard to their cost structure and their influence on the clinical result.
In Germany, uncemented and hybrid fixation are used for THA. In this study we investigated the differences in material costs, the duration of surgery, and the length of stay.
For each fixation technique a retrospective cost analysis was carried out, based on the data from the treatment documentation of the University Hospital for Orthopedics, Rostock (OUK). The mean values of the parameters and expenses have been reviewed with descriptive statistics for differences.
With regard to total costs and the contribution margin there was no statistically significant difference.
Although there are differences in individual cost areas, in total costs, cost advantages and disadvantages cancel each other out. Thus, from an economic perspective no particular technique can be recommended.
