Effect of a brief educational intervention on medical students' use of asthma devices.

Several studies have shown that a significant percentage of housestaff and attending physicians are deficient in both skill and knowledge of the metered-dose inhaler (MDI). There are no studies involving medical students, or any including the peak flow meter (PFM). The setting was a large health science center with investigators in private conference rooms with individual medical students. Twenty-two medical students in the last semester before graduation were scored in the use of these devices pre-education and post-education (instruction included both discussion and demonstration). Results revealed a lack of skill initially, followed by dramatic improvement after the intervention. The total number of correct steps for each device (MDI with spacer and PFM) improved significantly (p < 0.0001). This group of medical students was deficient in the use of common asthma devices. A short educational intervention was effective in improving skill.
