Pharmacoeconomic aspects of nicotine addiction treatment in patients with angina requiring cardiac surgery
Smoking is a major risk factor in patients with angina pectoris. Interventions that facilitate the rejection of it are an important part of the treatment. Aim. To analyze the cost effectiveness of the partial agonist of nicotinic receptors, varenicline, in patients with angina who require cardiac interventions. Material and methods. The estimation was conducted using a Markov model based on the results of clinical trials and epidemiological studies. The cost of treatment of complications were calculated on the basis of compulsory medical insurance rates for St. Petersburg in 2011 Results. The varenicline therapy in 70-year-old patients before cardiac surgery reduces hospital mortality at an extremely high cost-effectiveness (the cost of preventing one death - 148.8 thousand rubles). The cost/effectiveness ratio in the analysis for the period of survival of patients in this situation was 31.3 thousand rubles for 1 additional year of life. Life expectancy will be increased by an average of 0.147 years. Analysis for the period of survival of 50-year-old patients has shown that in patients after cardiac surgery cost-effectiveness of varenicline is extremely high (in the analysis from the perspective of the health care system the cost/effectiveness ratio was 36.0 thousand rubles for 1 additional year of life, in the analysis, taking into account the social perspective - 17.9 thousand rubles for 1 additional year of life). Increase in the life expectancy of 50 year-old patients will be 0.291 year in average. Conclusion. Varenicline therapy of patients with angina pectoris is the economy before cardiac surgery, and after their execution, and this applies not only young, but older patients. The desirability of varenicline including to federal and regional programs to reduce cardiovascular morbidity and mortality is shown.
