Study of Some Risk Factors in Acute Exacerbation of COPD at Tertiary Care Centre

Background: Respiratory symptoms of patients usually worsen, which may be beyond normal day to day variation this is nothing but an acute event of a disease leading to further change in medication. Acute exacerbation of Chronic obstructive pulmonary disease is defined as sudden worsening of symptoms like in breathlessness, chest pain, change in quantity and colour of sputum, fever, these symptoms usually last for several days. These symptoms are aggravated by environmental pollutants, bacterial and viral infections wherein infections usually lead to 75% or more of the exacerbations but improper inhaler technique is also one of the most important factors for causing exacerbation of Chronic Obstructive Pulmonary disease. Aims and Objectives: To study the risk factors for exacerbation of COPDs. Methods: Present sample consists of 51 diagnosed COPD patients who fulfilled eligibility criteria. Study was conducted in the department of Respiratory medicine from August 2016 to December2018. Detailed history along with general and respiratory system examination was done and findings were recorded. Results: Most of the study population was present between 51 to 60 years (41.2%) of age group and rest were in 41 to 50 years (29.4%) and more than 60 years (29.4%). There was male predominance (64.7%) amongst study population as compared to females (35.3%). 82.4% of study population were taking inhaler improperly. 64.7 % of study population were exposed to outdoor pollution. 43.1% of study population are exposed to indoor pollution. Conclusion: Environmental stress are also involved in acute exacerbation of chronic obstructive pulmonary disease apart from viral and bacterial infections. Improper technique of using inhaler was also the main risk. So patients are advised proper & regular use of inhaler technique. Indoor and outdoor pollution is also main risk factor for exacerbation so avoidance of exposure to biomass fuel and outdoor pollution should be considered.
