Management of patients with obstructive lung disease in South India: a retrospective study of spirometry and bronchodilator use in an urban health centre

ABSTRACT

Background: Based on the burden of obstructive lung diseases program (BOLD), the global prevalence of chronic obstructive pulmonary disease (COPD) was 11.7% in which 90% of the deaths occur in low- and middle-income countries. India and China are estimated to account for 66% of total global COPD mortality. The Indian Chest Society (ICS) recommends spirometry to document irreversible airflow limitation in patients suspected of having COPD. However, the reported usage of spirometry among primary care physicians in India is only 10-20% as primary health care centers in India are not equipped with spirometry or inhaler devices.Methods: A retrospective study was done on patients treated for respiratory symptoms with bronchodilators at an urban health centre to document the practice pattern of primary care physicians with regards to use of spirometry in patients on bronchodilators.Results: Of the 1196 patients on bronchodilators, spirometry was documented in 15.5%. Patients on inhalers, using more than one therapy and males less than 55 years were more likely to undergo spirometry. About 52.4% of patients who underwent spirometry were found to have post bronchodilator forced expiratory volume at first second (FEV1)/ forced vital capacity (FVC) less than 0.7 of which 43% had severe disease and 44% had poor post-broncho-dilator reversibility.Conclusions: Besides diagnostic spirometry, management guidelines for COPD should be complemented by health education to change patients’ perception of respiratory symptoms, increase awareness of COPD in those with risk factors and change their health seeking behaviour along with continuous professional development activities for primary care physicians.
