Is spa therapy cost-effective in rheumatic disorders?
OBJECTIVE
To evaluate the cost-effectiveness of spa therapy for rheumatic diseases and sequelae of bone and joint injuries.


METHODS
A prospective randomized, case-control design was used with health care cost reimbursements during the year before and after spa therapy as the measure of efficacy. Spa therapy is reimbursed by the national health insurance system in France, subject to prior agreement. The 220 patients who filed applications for spa therapy with the national health insurance payment center for northern France during the first half of 1994 were included in the study. Seventy-two patients met national health insurance system criteria for spa therapy (Group 1), the remaining 148 patients were assigned at random to spa therapy (Group 2, n = 74) or no spa therapy (Group 3, n = 74). This method allowed us to avoid selection bias during recruitment of our control group.


RESULTS
Perceived morbidity was evaluated based on health care utilization, expressed as numbers of health care investigations or procedures and as days of medication use in mean recommended dosages. Health care cost reimbursements by the national health insurance system failed to decrease during the year after spa therapy, and increased in those patients who had already received spa therapy on one or more occasions. Only in the first-ever spa patients were decreases in health care utilization in the area of rheumatology seen during the year after spa therapy; the largest decreases were for use of nonsteroidal antiinflammatory drugs (from 49 to 26 days) and muscle relaxants. No differences in health care utilization were found in patients who had received spa therapy on at least one other occasion. Also, when criteria for spa therapy were not met, no differences in health care utilization were found between patients who did and did not receive spa therapy.


CONCLUSIONS
These data suggest that current national health insurance policies regarding the reimbursement of spa therapy need to be reevaluated.
