Effectiveness of Various Methods of Teaching Proper Inhaler Technique: The Importance of Pharmacist Counseling

This article delves into the role of a pharmacist in patient inhaler education.  There were four different interventions that were compared in this study. The purpose of the study was to determine the efficacy of direct patient education vs. video or print education.

  1. Patient reads a metered dose inhaler (MDI) package insert pamphlet.
  2. Patient watches a Centers for Disease Control and Prevention (CDC) video demonstrating MDI technique.
  3. Patient watches a YouTube video demonstrating MDI technique
  4. Pharmacist gives patient direct instruction of MDI technique (2 minutes long)

This study had a patient population of 72 and each was screened for demographic information, including literacy. All patients used inhalers. These patients were randomized to one of the four interventions and then evaluated by their ability to demonstrate proper inhaler technique using a placebo MDI. The effectiveness of each intervention was measured by the patient’s ability to complete each step of proper inhaler technique, and no partial credit was given. The result of the study showed that only 29.2% of the patients were able to do this correctly. There was also a statistically significant increase in correct inhaler technique in the group of patients given direct inhaler technique education.

This study showed that pharmacists can positively influence patent inhaler outcomes (in comparison to other methods) by giving direct patient education. This is important for the advancement of our profession because it shows that we can provide care outside of simply dispensing medications. Studies like this may provide a framework for allowing pharmacists to provide other services.

What other services do you see pharmacists being able to provide in the future?
