Background: We evaluate the cost-effectiveness of the ‘Best Care’ integrated disease management (IDM) program for high risk, exacerbation prone, patients with chronic obstructive pulmonary disease (COPD) compared to usual care (UC) within a primary care setting from the perspective of a publicly funded health system (i.e., Ontario, Canada). Methods: We conducted a model-based, cost-utility analysis using a Markov model with expected values of costs and outcomes derived from a Monte-Carlo Simulation with 5000 replications. The target population included patients started in GOLD II with a starting age of 68 years in the trial-based analysis. Key input parameters were based on a randomized control trial of 143 patients (i.e., UC (n = 73) versus IDM program (n = 70)). Results were shown as incremental cost per quality-adjusted life year (QALY) gained. Results: The IDM program for high risk, exacerbation prone, patients is dominant in comparison with the UC group. After one year, the IDM program demonstrated cost savings and improved QALYs (i.e., UC was dominated by IDM) with a positive net-benefit of $5360 (95% CI: ($5175, $5546) based on a willingness to pay of $50,000 (CAN) per QALY. Conclusions: This study demonstrates that the IDM intervention for patients with COPD in a primary care setting is cost-effective in comparison to the standard of care. By demonstrating the cost-effectiveness of IDM, we confirm that investment in the delivery of evidence based best practices in primary care delivers better patient outcomes at a lower cost than UC. Highlights I. Interventions that can reduce the frequency and severity of exacerbations in patients who sufer from COPD have the potential to reduce the fnancial burden of COPD on the health system; II. Tis is the frst study that demonstrates the cost-efectiveness of integrated disease management for patients who sufer from COPD within a primary care environment; II. Tis study makes the case for embedding Certifed Respiratory Educators (CREs) within the primary care environment to improve the quality of life of patients who sufer from COPD, as well as alleviating unneces sary health services utilization and decreasing the overall fnancial burden of the disease on the health system.
