Abstract BACKGROUND: To quantify short-term benefits of total hip replacement, prognostic factors of the outcome, and to assess hospital costs of this surgical procedure in Catalonia, Spain. PATIENTS AND METHODS: Multicentric prospective study in seven hospitals in Catalonia. All patients undergoing this procedure in one year were included. They were evaluated prior to the operation, and six months later. This evaluation involved: clinical assessment, the Hip Pain and Function Scale, the Nottingham Health Profile (NHP), and the EuroQol (EQ-5D), in order to measure cost-utility. Hospital costs were estimated by means of a specific questionnaire. RESULTS: Information was obtained for 332 patients. The mean age was 65 years (range: 27-89 years); 58\% were women; the most common diagnosis was arthritis; 59\% of patients had associated pathology and 13\% presented some type of postoperative complication. The improvement in health status was important according to all instruments. An outcome of "excellent" or "good" was achieved by 70.8\% of the patients, in terms of hip function and pain. The factors associated with not achieving an outcome of this level were: associated pathology, complications, diagnoses other than arthritis, and operation carried out in a tertiary hospital. The total cost of the procedure was 838,480 pesetas. This average varied significantly with the cost of the prosthesis, and as a function of the length of stay. The three-year cost-utility of the procedure was estimated as 507,500 pesetas. CONCLUSIONS: Total hip replacement greatly improves the pain, hip function and overall perceived health of the patient. This improvement is greater among patients with a diagnosis of arthritis, with good overall health, operated on by a surgeon experienced in this procedure. The benefit is high in relation to the cost, although there is a margin for improvement, reducing complications, shortening length of stay, and controlling the price of implants.
