Abstract

Context: Inhalation therapy plays a major role in treatment of respiratory diseases. Correct inhalation technique is crucial for effective clinical outcomes.
Aims: The aim of this study was to evaluate and analyse technique of use of Metered Dose Inhaler (MDI) and Dry Powder Inhaler (DPI) in patients with respiratory disease.
Settings and Design: This observational study was conducted at pulmonary outpatient department of a tertiary care hospital.
Materials and Methods: 30 patients were enrolled using convenience sampling. Participants’ demographic and disease specific data was recorded. Participants were asked to use their inhaler just as they would at home. The technique of device use was observed and recorded using inhaler specific checklists. Data collected was analyzed using descriptive statistics.
Results: Out of 30 patients 26 were using MDI, 23 of which (92%) performed at least 1 error. Among 4 patients using DPI, 3 (75%) performed at least 1 error. Patients using MDI for more than 1 year performed less errors compared to those who had been using MDI for less than 1 year, however the difference observed was not significant (n=26, p= 0.304). 29 patients (96%) received education about inhaler device use. The most common incorrectly performed steps were “complete exhalation” and “breath hold.”
Conclusions: 92% of MDI and 75% of DPI users made at least one error during the inhalation maneuver despite majority being educated about inhaler technique. The most frequently performed incorrect steps for MDI and DPI were “Complete exhalation” and “Breath hold”.
