Recently, bronchial asthma is considered as a heterogeneous disease characterized by chronic airway inflammation and respiratory symptoms, which vary in time and intensity and manifest together with variable obstruction of the airways. Asthma is one of the most common chronic respiratory diseases in primary care. Patients with certain respiratory symptoms seek for medical aid initially in primary care physicians, such as therapeutists, general practitioners, and family physicians, who can suspect and diagnose chronic respiratory diseases such as bronchial asthma, chronic obstructive pulmonary disease (COPD), allergic rhinitis, etc. Currently, untimely diagnosis of asthma and late initiation of anti-inflammatory treatment are widespread, mainly due to insufficient knowledge of primary care physicians on diagnostic criteria and therapeutic standards for asthma. Feasible and convenient algorithms for asthma diagnosis and treatment in primary care were developed by experts of Russian Respiratory Society and Russian Association of Allergologists and Clinical Immunologists. A therapeutic algorithm for asthma treatment in primary care institutions uses an approach considering symptom severity both in patients with newly diagnosed and previously treated for asthma. Diagnostic tools, such as a questionnaire for asthma diagnosis and an algorithm for differential diagnosis between asthma and COPD are mainly intended to facilitate diagnosis of chronic respiratory disease, particularly bronchial asthma, by a primary care physician and to improve the healthcare quality for these patients.
