Abstract
It is known that many housestaff physicians are unable to demonstrate perfect metered dose inhaler (MDI) technique. This study assessed whether a single teaching session for house staff physicians would significantly improve their MDI technique. Thirty-eight pediatric house staff physicians were asked to demonstrate MDI technique with a placebo MDI. The physicians were evaluated on the following seven steps: (1) shaking the MDI and removing the cap, (2) exhaling prior to MDI use, (3) holding the MDI upright, (4) proper timing of actuation, (5) a slow inspiratory effort, (6) one MDI actuation per breath, and (7) holding the breath > or = 5 seconds. A 20-minute teaching session and demonstration of proper MDI technique was then given. At the end of this session all residents were eventually able to demonstrate proper technique. Two months following this educational session the same house staff physicians were re-evaluated on their MDI technique. Initially, ten participants (26%) demonstrated perfect technique. Two months postinstruction the same number of physicians (ten) demonstrated perfect technique. Only six physicians demonstrated perfect technique at both evaluations. Three of the seven steps showed enough change from the f...Continue Reading
