Post-marketing pharmaco-economics evaluation of Jinye Baidu Granules / 中国中药杂志

ABSTRACT

To evaluate the economy and applicability of Jinye Baidu Granules in the treatment of acute upper respiratory tract infection, a randomized, double-blind, positive drug parallel control clinical trial was conducted in this study. Stratified block random, double-blind and double simulation test was used. The experimental group took Jinye Baidu Granules, 10 g/time, three times a day, and Compound Shuanghua Granules placebo, 6 g/time, four times a day. The control group took Compound Shuanghua Granules, 6 g/time, 4 times a day, and Jinye Baidu Granules placebo, 10 g/time, 3 times a day. The course of treatment was 5 days. The total cost of this study included direct medical cost and indirect medical cost. The incremental cost-effect analysis method was used for evaluation. Treeage Pro software was used to build a pharmaco-economics model and make statistical analysis. Patients from 10 hospitals were divided into experimental group(304 cases) and control group(302 cases). The baseline values of age, sex ratio, clinical symptoms and signs scores, and important physical examination indexes of the two groups were compared. After 5 days of treatment, the cost per capita of the experimental group was(388.06±94.17) Yuan, and that of the control group was(378.47±95.46) Yuan. The cost of direct medical treatment per capita was(271.24±54.11) Yuan for the experimental group and(264.88±112.71) Yuan for the control group. The average cost of indirect medical treatment was(116.82±82.75) Yuan in the experimental group and(113.59±87.77) Yuan in the control group, with no significant difference in the cost of medical treatment per capita, the cost of direct medical treatment per capita and the cost of indirect medical treatment per capita between both groups. The results of incremental cost-effect analysis based on the total score difference in symptoms and signs after 5 days of treatment showed that ICER=23.39 Yuan/score, which was less than the willingness to pay 100 Yuan/score determined through expert interviews. The experimental group had economic advantages over the experimental group, with the economic probability of 53%. Sensitivity analysis supported the robustness of the results. The results of incremental cost-effect analysis based on the total recovery rate of symptoms and signs showed that compared with the experimental group, the control group had lower cost, better effect and absolute economic advantage, with a corresponding probability of 55%. Based on the above results, it is concluded that there is no significant difference in economic outcome between Jinye Baidu Gra-nules and Compound Shuanghua Granules in the treatment of acute upper respiratory tract infection.
