Study Objectives: Non-smoker Patients of asthma who are chronically exposed to the side smoke (ETS, Environmental Tobacco Smoke) from others have higher morbidity. The present study was designed to look if ETS – exposure was an important factor precipitating acute asthma. Design: Interviewing patients of asthma for exposures in the 24 hours preceding the interview to known triggers and ETS with the help of pre-designed questionnaire. Setting: Emergency Room and Chest Clinic of a 100 bed, tertiary care, referral, university-level institute. Participants: One hundred consecutive patients with acute exacerbations (Group I) and another 100 with stable, non-acute asthma (Group II). Results: There was a significant higher (p<0.01) prevalence of exposure to ETS in patients with acute exacerbations. Quantitatively, measured in ‘man-hours’, there was a higher exposure in this group. Sixty percent asthmatics had one or other symptom on acute exposure to ETS. Conclusions: Exposure to ETS causes acute worsening in non-smoker asthmatics.
