Factors influencing bronchial asthma exacerbations with special emphasis on inhaler usage

Jayasri Helen Gali, Harsha Vardhana Varma


Background: Study of risk factors help make patients aware about them and they can be taught to take proper precautions to prevent the exacerbation of asthma. Objective was to study factors influencing bronchial asthma exacerbations with special emphasis on inhaler usage.

Methods: A hospital based cross sectional study was carried out over a period of three months among 218 eligible patients with asthma who could give written informed consent and willing to participate in the present study and the data was recorded in a pre tested, semi structured study questionnaire. The data was recorded in the Microsoft Excel Worksheet and analyzed using proportions and mean+2SD.

Results: We found that advanced age, exposure to dust, fumes and allergens, lower social class, presence of other co-morbidities, irregular use of inhalers, and not demonstrated the technique of proper inhaler use were significantly associated with exacerbation of bronchial asthma. Other factors like mean duration of illness, mean duration of use of inhalers, gender, presence of allergic rhinitis, type of device used for inhalation and taking consultation from pulmonologist were not significantly associated with exacerbations of asthma.

Conclusions: Demonstrating and teaching the patient on how to use the device of inhaler plays a significant role in reducing the risk of exacerbation of bronchial asthma.
