| Abstract: | One hundred and- eighteen newly diagnosed patients with Graves' disease were treated by tapazole for 6 months (short-term course) and followed up for another 12 months. Forty three percent remission rate was found in this group. A regular course of antithyroid drug therapy for 1.5-2 years with 50% remission rate was taken as control. Cost-effectiveness analysis was made to compare the cost in the two different kinds of therapy. The results showed that the total costs of the treatment per 100 cases were 17,746 yuan for the short-term therapy and 30,708 yuan for the regular therapy, with an average of 412.7 yuan and 614.2 yuan per case respectively. In comparison with the short-term therapy, the regular course could remit 7 more cases at a cost of 12,962.40 yuan, with an average of 1851.80 yuan per case. Therefore, the cost was high by prolonged course of therapy to increase slightly remission rate, although it could remit a few more cases. This study suggests that six-month treatment is preferable for those who live in the rural or remote area where the economy was less developed. A longer course of therapy may be unnecessary for those who have been treated by antithyroid drugs for 6 months or longer and are predicted to obtain a possible prolonged remission. |
