Conclusions A simulated clinical trial suggests that a community health worker-led diabetes intervention is a cost-effective way to reduce diabetes-related complications for uninsured Mexican Americans during a 20-year horizon in comparison to usual medical care.

Background Limited evidence exists regarding the long-term effects of community health worker-led diabetes management programs on health outcomes and cost-effectiveness, particularly in low-income, ethnic minority populations.

Purpose To examine the long-term cost-effectiveness and improvements in diabetes-related complications of a diabetes education and management intervention led by community health workers among uninsured Mexican Americans.

Methods Clinical data, changes in hemoglobin A1c over 12 months, and costs from an RCT of 180 uninsured Mexican Americans with type 2 diabetes conducted in 2006 were utilized for secondary analyses in 2012. Simulation modeling was used to estimate long-term cost and health outcomes using the validated Archimedes Model. The absolute differences for the incremental cost-effectiveness ratios and cumulative incidence of diabetes-related complications were derived by comparing intervention and control groups.

Results During a 20-year time horizon, participants who received the intervention would be expected to have significantly lower hemoglobin A1c levels (p<0.001), fewer foot ulcers (p<0.001), and a reduced number of foot amputations (p=0.005) in comparison with a control group receiving usual medical care. An incremental cost-effectiveness ratio of $355 per quality-adjusted life year gained was estimated for intervention participants during the same time period.
