A recent cluster randomized trial evaluating a multicomponent intervention showed significant reductions in blood pressure in low-income hypertensive subjects in Argentina.


To assess the cost-effectiveness of this intervention.


A total of 1432 hypertensive participants were recruited from 18 primary health care centers. The intervention included home visits led by community health workers, physician education, and text messaging. Resource use and quality of life data using the three-level EuroQol five-dimensional questionnaire were prospectively collected. The study perspective was that of the public health care system, and the time horizon was 18 months. Intention-to-treat analysis was used to analyze cost and health outcomes (systolic blood pressure [SBP] change and quality-adjusted life-years [QALYs]). A 1 time gross domestic product per capita per QALY was used as the cost-effectiveness threshold (US $14,062).


Baseline characteristics were similar in the two arms. QALYs significantly increased by 0.06 (95% confidence interval [CI] 0.04-0.09) in the intervention group, and SBP net difference favored the intervention group: 5.3 mm Hg (95% CI 0.27-10.34). Mean total costs per participant were higher in the intervention arm: US $304 in the intervention group and US $154 in the control group (adjusted difference of US $140.18; 95% CI US $75.41-US $204.94). The incremental cost-effectiveness ratio was $3299 per QALY (95% credible interval 1635-6099) and US $26 per mm Hg of SBP (95% credible interval 13-46). Subgroup analysis showed that the intervention was cost-effective in all prespecified subgroups (age, sex, cardiovascular risk, and body mass index).


The multicomponent intervention was cost-effective for blood pressure control among low-income hypertensive patients.
