Impact of a clinical pathway and implant standardization on total hip arthroplasty: a clinical and economic study of short-term patient outcome.

This study evaluates the impact of a clinical pathway (CP) and a hip implant standardization program (HISP) on the quality and cost of total hip arthroplasty (THA). Two hundred six unilateral THA operations for osteoarthritis were evaluated: 89 operations were performed in 1991 without a CP or HISP (4-year follow-up period); 117 operations were performed in 1993 with a CP and HISP (2-year follow-up period). All patients had good clinical results and excellent outcomes with short-term follow-up evaluation. No differences were seen between groups in terms of patient ratings of outcome and satisfaction or in terms of complication rates in the hospital. Implementation of a CP and HISP did not adversely affect the short-term outcome of THA but did reduce hospital length of stay and hospital cost for THA.
