Abstract: | BackgroundCardiovascular diseases are the leading cause of death. Pharmacist-led medication review with follow-up might be cost-effective preventing cardiovascular diseases.ObjectiveTo undertake a cost–utility analysis of the addition of pharmacist-led medication review with follow-up to usual care compared to usual care alone for cardiovascular outpatients.Materials and methodsA state-transition microsimulation model was built to project outcomes over a lifetime time horizon. Inputs from a cluster randomized controlled trial conducted in primary health care centers in Chile with full-time pharmacists were used. Probabilities were estimated using patient-level data. Utilities and costs associated with each health state were obtained from the literature, whereas the intervention costs were retrieved from the trial. The public third-party payer perspective was used. Uncertainty was evaluated through one-way and probabilistic sensitivity analyses.ResultsFor the base case analysis, an incremental cost-effectiveness ratio of $963 per quality-adjusted life-year was observed which was considered cost-effective. The results were robust to sensitivity analyses and were driven by decreased cardiovascular events resulting in lower mortality.ConclusionsMedication review with follow-up was deemed a cost-effective addition to usual care with low uncertainty. |
