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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
