Abstract

Background and Objectives: To assess the impact that pharmacist education has on proper inhaler technique and adherence in a teaching clinic. Methods: This was prospective, non-randomized, pre-test/post-test study. Patients were 18 years or older, had a diagnosis of asthma or COPD, and prescribed at least 1 inhaled medication. Initial visits consisted of a baseline asthma control test (ACT) or COPD assessment test (CAT), the Test of Adherence to Inhalers (TAI), and a baseline inhaler technique evaluation. The pharmacist then educated the patient. Then inhaler technique was assessed again (post-education inhaler technique evaluation #1). Follow-up visits occurred 4 to 8 weeks later. ACT or CAT and TAI test were administered and inhaler technique was assessed again (post-education inhaler technique #2). The primary outcome was the comparison of the percentage of correct steps performed from baseline to post-education inhaler technique evaluation #1 and from baseline to post-education inhaler technique evaluation #2. Results: Eighteen patients were included, with a mean age of 58 years old. Over half had asthma, were female and African American. There was a significant difference in inhaler technique from baseline to post-education inhaler evaluation #1 and from baseline to post-education inhaler evaluation #2. The most common step missed was no exhalation before inhalation. There was no significant difference when comparing the individual and overall TAI test scores from initial to follow up visit. Conclusions: This study supports pharmacist-led inhaler technique education.
