RESUMO
OBJECTIVE: Estimate the cost-effectiveness of a nurse-led home visit (HV) intervention as compared with the standard HF management, within a randomized clinical trial in Brazil. STUDY DESIGN: Cost-effectiveness study within a randomized trial. METHODS: To assess the cost-effectiveness of four home visits and four telephone calls by nurses in the management of patients with HF within a randomized clinical trial (RCT: NCT01213875) in a perspective Public (PHS-Public Healthcare System) and private healthcare systems of Brazil during time frame of 24 weeks. The outcome was a composite endpoint hospital readmission rate (first visit to the emergency room (ER) and hospital readmission), or all-cause death and incremental cost-effectiveness ratio (ICER) of the study intervention to conventional management. RESULTS: Home-based intervention was associated with a reduction in composite endpoint (RR 0.73; 95% confidence interval 0.54 - 0.99; P = 0.049), but at greater cost from the PHS perspective. The ICER at 24 weeks was R$585 per hospital readmission visit prevented. Within the private health insurance framework, home visits were associated with lower costs and lower readmission rates. Results were sensitive to the relative risk of the study intervention, admissions and intervention costs. CONCLUSIONS: In Brazil, an intervention based on nurse-led home visits of patients with HF showed a favorable cost-effectiveness profile within the framework of the PHS and was dominant within the private healthcare system. Our analysis suggests that implementation of this program could not only benefit patients, but also provide a financial incentive to health administrators.
