Background: Ideally, analysis of the cost-effectiveness of a health promotion intervention is integrated into a comprehensive evaluation plan prior to program implementation. However, programmatic needs and constraints may require a cost-effectiveness analysis (CEA) after a program has been implemented (post-hoc), requiring the use of available evaluation data.

Methods: We developed and implemented an eight-step process to analyze the cost-effectiveness of a community-based intervention to reduce cardiovascular disease risk in a rural region in Illinois: 1. Catalogue available data; 2. Determine additional data required; 3. Determine analytic options; 4. Understand equation components; 5. Determine equation variables; 6. Specify analytic assumptions; 7. Run analysis; and 8. Interpret results in the context of assumptions. 

Results: Using the post-hoc CEA model we determined annual program costs ($30,427.55), per person cost ($136.06), and incremental cost ($36.59). By combining these data with participants’ mean increase in moderate physical activity (approximately 1 additional day/week), we demonstrated a method for extrapolating return on investment, Quality Adjusted Life Years (QALY), and stroke-risk reduction. We applied the method within the context of a cardiovascular risk reduction intervention to demonstrate the potential and limitations of this method.

Conclusion: We developed an eight-step process to implement a post-hoc CEA within an existing cardiovascular risk reduction intervention. Given that many health promotion programs operate with limited budgets and may lack access to health economists, this method is feasible for application to demonstrate economic benefits of other health promotion programs.
