Effects of timing of thoracoscopic surgery for primary spontaneous pneumothorax on prognosis and costs - 25/08/11
Abstract |
Background |
Primary spontaneous pneumothorax recurs frequently. Timing of video-assisted thoracoscopic surgery to prevent recurrence is controversial and long-term costs remain inconclusive.
Methods |
We constructed a Markov model to assess the effect of different timings for surgery on health status, costs, and cost effectiveness from the payers' perspective in Japan.
Results |
During 1-year follow-up, the proportions of patients who underwent surgery after the first and second drainage were 46% and 36%, respectively. Average 1-year cost for surgery at the first episode was highest (U.S. $6,556), followed by the second (U.S. $2,988) and the third (U.S. $2,532). Incremental cost for surgery at the first episode compared with the second and that at the second episode compared with the third were U.S. $30,564 and U.S. $29,915 per quality-adjusted life year, respectively. Sensitivity analyses showed utility and length of hospital stay for surgery have the strongest effect on incremental cost.
Conclusions |
Thoracoscopic surgery at the first episode significantly increased costs, but could be acceptable from a cost-effectiveness perspective.
