Résumé
Objective: Early detection of Chronic Obstructive Pulmonary Disease in apparently healthy attendants of tertiary care hospital and assessment of its severity
Study Design: Cross-sectional, observational study
Place and Duration of Study: Study was conducted from January 2015 to July 2015 at Dow University Hospital, Ojha campus
Methodology: A screening method was designed for apparently healthy individuals including attendants of patients, hospital staff, faculty and students, belonging to age group 18-60 years after excluding severe obesity and already diagnosed respiratory and cardiovascular diseases by means of history. Each participant performed pulmonary function tests via spirometer after filling a questionnaire based on various risk factors and symptoms of chronic obstructive pulmonary disease [COPD]. Data was entered and analysed by SPSS-20
Results: Out of the 517 participants, 122 [23.6%] were found to have COPD diagnosed by means of spirometry. Out of these, 23 [4.4%] had COPD stage I, 42 [8.1%] had COPD II, 34 [6.6%] had COPD III, and 23 [4.4%] had COPD IV. Exposure to smoking, wooden stoves, pesticides, biomass fuel, aerosol sprays, gas grill and vehicle exhaust were found to be statistically significant factors in relation to development of COPD
Conclusion: Apparently healthy individuals may have underlying COPD and active screening by means of spirometry plays vital role in early detection of COPD. Smoking and exposure to certain hazardous environmental pollutants are responsible for the development and progression of COPD
