Abstract

Background: Uncontrolled asthma results in significant costs to families and society. To achieve the best possible results for asthma control, the National Asthma Education and Prevention Program recommends that providers demonstrate and assess metered-dose inhaler–spacer (MDI-S) technique at each medical visit. However, healthcare professionals are not always well-versed in the correct usage of inhalation devices. Our study aims to assess the knowledge and technique of pediatric healthcare professionals about the use of MDI-S and to assess if these can be improved with a brief video-based intervention. Methods: Study participants were recruited from pediatric residents, pediatric advanced practice providers, pediatric hospitalists, general pediatric clinic attendings, and pediatric nurses. Each participant was asked to demonstrate how to administer 2 puffs of albuterol to a child using a mannequin head and training MDI-S system. Performance was assessed against a 10 step standardized checklist. Participants were then shown a 2 minute video about how to administer albuterol via MDI-S. Finally, participants demonstrated again how to administer 2 puffs of albuterol using the same equipment and were assessed with the same 10 step checklist. Results: A total of 65 participants participated in the study. Pre-intervention, participants scored an average of 5.38 (1.5), with 23.0% (n=15) of participants performing at least 7 out of 10 steps correctly. After watching the video intervention, participants’ average scores improved to 7.98 (1.2, p <0.001) with 87.7% (n=57) of participants performing at least 7 out of 10 steps correctly. Conclusions: Participants’ ability to administer albuterol using MDI-S improved significantly after watching a brief video. However, only 4.6% (n=3) participants could perform all 10 steps correctly even after the intervention, indicating more reinforcement for designated steps may be required.
