Control of bronchial asthma in Russia: results of NIKA multi-center observational study

Abstract

Summary. Asthma control level was evaluated in 1 000 patients treated in 26 outpatient centers at 12 cities of Russian Federation. Asthma control level was assessed clinically and with special questionnaires ACQ-5 and ACT. Results were referred to GINA criteria. Well-controlled asthma was found in 23 % of patients, partly controlled and poorly controlled asthma was diagnosed in 25 % and 42 % of patients, respectively. Attendant physicians misestimated asthma control level in 49 % of cases. ACQ-5 and ACT questionnaires equally improved estimation of asthma control (64 % and 60 % of adequate estimates, respectively) however, ACT questionnaire demonstrated systematic bias to overestimated asthma control when compared to GINA criteria.
