[Cost-benefit analysis of [224Ra] radium chloride therapy for ankylosing spondylitis (Bekhterev's disease)].

Background And Purpose: Cost-benefit analyses are helpful in setting priorities for funding health-care programs. The authors studied the cost/benefit of treatment with radium-224 compared to the treatment without radium-224 in patients with ankylosing spondylitis (AS).

Material And Methods: The data of a 2-year retrospective observational study were used to estimate cost/benefit of [224Ra] therapy. Twelve patients treated with [224Ra], complete recruit in AOK Saxony, matched (age, gender, employment status) with twelve patients receiving conservative treatment without [224Ra], were compared for lost productivity and direct medical costs, such as doctor visits, medication and hospitalization, 1 year before and after treatment.

Results: 1 year after the first i.v. injection of [224Ra], all cost factors in the case group were reduced compared to 1 year before treatment with [224Ra] (hospitalization 29.4%, doctor visits 23.5%, medication 9.4%, and lost productivity even 82.3%). The total costs decreased by an average of 3,870 Euros. Because of the small sample the differences showed a trend but were not significant.

Conclusion: The use of [224Ra] in patients with AS seems to reduce lost productivity and direct medical costs, but additional studies based on more patients and long-term data are needed.
