RESUMO
Aim To analyze the cost-effectiveness of pneumococcal vaccination in 40- and 65-year-old patients with chronic heart failure (CHF).Material and methods Analysis was performed by Markov modeling from the perspective of the healthcare system. The evaluation was based on Russian epidemiological data taking into account results of international studies. The analyzed schedule of vaccination included one dose of 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent polysaccharide vaccine (PPSV23) after one year and vaccination with only one dose of PCV13. The time horizon of the study was 5 years. Costs and life expectancy were discounted at 3.5% per year.Results The cost-effectiveness of vaccination for both 65-year-old and 40-year-old CHF patients is very high: the incremental cost of one additional QALY (Quality-Adjusted Life Year) for PCV13+PPSV23 vaccination is 113.24 thousand rubles, while vaccination with PCV13 entails a reduction in costs by 556.50 rubles per one vaccinated patient. For vaccination of 40-year-old CHF patients with PCV13+PPSV23, the incremental costs per 1 QALY will be 519.72 thousand rubles, while for vaccination with PCV13 it will be 99.33 thousand rubles.Conclusion Pneumococcal vaccination of CHF patients reduces the associated morbidity and mortality and is highly cost effective.
