Aim. To study clinical and cost effectiveness of training of young patients with arterial hypertension (HT) in the health school in comparison with individual counseling.Material and methods. Hypertensive outpatients (n=114) at the age of 18-27 years were included into the study. Patients were randomized into 2 groups: “Health school” and "Typical practice". “Health school” patients received special training course “School health for patients with HT." Patients of the "Typical practice" had individual consultation. Clinical and cost analysis was performed in 6, 12 and 36 months of the follow-up.Results. The total cardiovascular risk in patients of “Health school” and "Typical practice" groups after 12 months decreased from 15.85±3.47% to 7.22±2.59% and from 15.60±3.34% to 11.29±4.14%, respectively, after 36 months to 10.77±3.18% and to 11.40±3.93%, respectively. Cost of 1% reduction in the total cardiovascular risk was 3425.1 and 190.4 rubles per one patient in “Health school” and "Typical practice" groups, respectively.Conclusion. The more time after the training course passes, the more its clinical and cost effectiveness reduces. This requires a follow-up care and repeated preventive counseling of these patients.
