Objective: To compare the cost-effectiveness of two anti-hypertensive therapy regimens, Compound anti-hypertensive tablets and other common anti-hypertensive agents, in the treatment program of Primary Hypertension.
Methods: We conducted a cost-effectiveness analysis based on a community trial. Two communities' primary hypertensive patients were enrolled to receive different therapy drugs: Compound anti-hypertensive tablets (Group A) or other common anti-hypertensive agents (Group B). Blood pressure, medicine used, and adverse drug reactions were observed and recorded for one year, and then cost-effectiveness ratio of the two groups and incremental ratio were calculated. We considered a 30% drug price fluctuating load to make the sensitivity analysis.
Results: 2505 cases were enrolled with 1529 cases in group A and 976 cases in group B. The cost-effectiveness ratios were 418.1 and 1057.7 for Group A and B respectively while the incremental cost-effectiveness of Group B vs. Group A was 19 202.2. The results were insensitive to variation in the costs of drugs over clinically reasonable ranges.
Conclusion: Compound anti-hypertensive tablets appeared to be relatively cost-effective when compared to common drugs for the treatment of primary hypertension.
