Cost-effectiveness of the CNIC-Polypill versus separate monocomponents in cardiovascular secondary prevention in Spain.

INTRODUCTION AND OBJECTIVES

Despite advances in treatment, cardiovascular disease is the second leading cause of death in Spain. The objective of this study was to determine the cost-effectiveness of the CNIC-Polypill strategy (acetylsalicylic acid 100 mg, atorvastatin 20/40 mg, ramipril 2.5/5/10 mg) compared with the same separate monocomponents for the secondary prevention of recurrent cardiovascular events in adults in Spain.

MATERIALS AND METHODS

A Markov cost-utility model was adapted considering 4 health states (stable, subsequent major adverse cardiovascular event, subsequent ischemic stroke and death) and the SMART risk equation over a lifetime horizon from the perspective of the Spanish National Healthcare System. The CNIC-Polypill strategy was compared with monocomponents in a hypothetical cohort of 1000 secondary prevention patients. Effectiveness, epidemiological, cost and utilities data were obtained from the NEPTUNO study, official databases and literature. Outcomes were costs (in 2021 euros) per life-year (LY) and quality-adjusted LY (QALY) gained. A 3% discount rate was applied. Deterministic one-way and probabilistic sensitivity analyses evaluated the robustness of the model.

RESULTS

The CNIC-Polypill strategy in secondary prevention results in more LY (13.22) and QALY (11.64) gains at a lower cost than monocomponents. The CNIC-Polypill is dominant and saves є280.68 per patient compared with monocomponents. The probabilistic sensitivity analysis shows that 82.4% of the simulations are below the threshold of є25,000 per QALY gained.

CONCLUSIONS

The CNIC-Polypill strategy in secondary cardiovascular prevention is cost-effective compared with the same separate monocomponents, resulting in a cost-saving strategy to the Spanish National Healthcare System.
