A single teaching session improved metered dose inhaler (MDI) technique for some physicians, but perfect technique was not sustained. Repeated education is necessary for housestaff physicians to master MDI use.

Area of Science:

  • Medical Education
  • Pulmonary Medicine
  • Clinical Skills Training

Background:

  • Many housestaff physicians exhibit suboptimal technique when using metered dose inhalers (MDIs).
  • Improper MDI technique can lead to reduced medication efficacy and poorer patient outcomes.

Purpose of the Study:

  • To evaluate the effectiveness of a single educational session on improving housestaff physicians' MDI technique.
  • To determine if short-term improvements in MDI technique are maintained over time.

Main Methods:

  • Thirty-eight pediatric housestaff physicians were assessed on seven key steps of MDI technique.
  • A 20-minute teaching session with demonstration was provided.
  • Physicians were re-evaluated two months post-intervention.

Main Results:

  • Initially, only 26% of physicians demonstrated perfect MDI technique.
  • Two months after the educational session, the percentage of physicians with perfect technique remained unchanged.
  • Statistically significant improvements were observed in specific steps, including timing of actuation, inspiratory effort, and breath-holding duration.

Conclusions:

  • A single educational intervention is insufficient to ensure sustained, perfect MDI technique among housestaff physicians.
  • While some technique aspects improved, overall perfect MDI use was not achieved long-term.
  • Repeated and ongoing MDI technique education is recommended for housestaff physicians.
