Background: Current practice at CCHMC for inpatients with asthma is to have the caregiver demonstrate effective MDI technique prior to patient’s discharge. Currently we do not assess the caregivers’ knowledge prior to asthma education. The purpose of this study was to evaluate the implementation of an assessment tool to measure baseline understanding and technique for caregiver administration of MDI’s to pediatric patients. We tested the hypothesis that observed MDI technique was improved following asthma education by a trained Respiratory Therapist. Methods: A data sheet was created and implemented that allowed Respiratory Therapists to observe patient or caregiver MDI knowledge and technique before and education. Respiratory Therapists on the asthma impatient unit were all trained and checked off on MDI technique prior to implementation to create interrater reliability. Education was differentiated between administering the MDI with an aero chamber and mouthpiece, and administering the MDI with an aero chamber and mask. There were 9 observational data points for the mask group and 12 observational data points for the mouthpiece group. Percentages of correct technique were calculated for each observational category and statistical analysis was performed in SigmaPlot version 11. A Mann Whitney Rank Sum Test was used to compare overall improvement pre and post education for each group. Significance was set at p = < .05. Results: In the mask group, mean correct technique observed pre education was 91% (.13), and .97(.06) in the post education group, (p=.04). In the mouthpiece group, mean correct technique observed pre education was 91% (.11), and .88 (.21) in the post education group, p= .8. Discussion: Effective MDI technique is important for home management of asthma and preventing hospital admissions. Measuring baseline knowledge and technique for patients and caregivers can be an effective tool in assessing asthma education needs. In our cohort of patients, overall knowledge and technique significantly improved in the mask group. Although there was no difference, in the overall correct technique in the mouthpiece group, individual categories and assessment points during the process were improved. Sponsored Research - None
