Influence of Pharmacist Counselling on Inhaler Usage Technique on Therapeutic Outcomes in Asthma and Chronic Obstructive Pulmonary Disease Patients

An open label prospective interventional study was conducted on asthma and chronic obstructive pulmonary disease patients to assess the influence of pharmacist provided education on inhaler usage technique and its impact on therapeutic outcomes in patients with Asthma and chronic obstructive pulmonary disease. The study was approved by the institutional ethics committee and conducted in the pulmonology department of Kamineni Institute of Medical Sciences, Narketpalli, Telangana. Written informed consent was obtained from the recruited study patients. A suitably designed data collection form was designed to capture disease and lab details i.e. forced expiratory volume in the 1st second. A newly constructed and validated knowledge, attitude and practices questionnaire was administered to assess the knowledge about the disease and its management. An inhaler checklist was applied to every patient to assess the inhaler usage technique and provided suitable guidance to use the inhaler effectively and assessed the impact of education on the patient's therapeutic outcomes. Among the 20 patients, 11 (55 %) were females and 9 (45 %) were males. The mean age of the study patients was 54 +/- 3 y. A significant improvement in knowledge, attitude and practices scores was observed in the post-counselling stage (p<0.001) and inhaler usage technique (p<0.001) among the patient after providing the counselling. Correct education about disease and inhaler usage techniques had shown an improvement in patient's therapeutic outcomes.
