Understanding the Knowledge Gap and Assessing Comfort Level among Healthcare Professionals Who Provide Inhaler Education.

Inhaled medications play a pivotal role in the management of COPD and asthma. Provider knowledge and ability to teach various devices is paramount as poor inhaler technique directly correlates with worse disease control. The goal of our survey was to assess the knowledge and comfort level with various inhaled devices among providers involved in patient inhaler education. We constructed a 20-question survey consisting of a five-question Likert scale-based comfort assessment and a 15-question multiple-choice inhaler knowledge test that was distributed both internally and nationwide. Groups surveyed included internal medicine residents, family medicine residents, pulmonary fellows, respiratory therapists, nursing staff, and pharmacists. A total of 557 providers responded to the survey. The overall correct response rate among all respondents was only 47%. There was no significant difference between correct response rates among prescribers (internal medicine residents, family medicine residents, and pulmonary fellows) and non-prescribers (respiratory therapists, nursing staff, and pharmacists), 47% and 47%, respectively ( = 0.6919). However, respiratory therapists had the overall highest correct response rate of 85%. Over 72% of respondents indicated that they educate patients on inhaler technique as part of their clinical duties. Furthermore, the correct response rates for various inhaler devices varied with 55% among metered dose inhalers, 52% among dry powder inhalers, and 34% among soft-mist inhalers. Our study reveals that there is a continued need for education on the subject of inhaler devices among providers given their overall poor knowledge, particularly in an era of fast-changing inhaler devices. We continue without knowing what we teach.
