Demonstrating and Assessing Metered-Dose Inhaler–Spacer Technique

Abstract

The National Asthma Education and Prevention Program recommends that providers demonstrate and assess metered-dose inhaler–spacer (MDI-S) technique at each medical visit. To examine practice behaviors and perceived barriers to demonstrating and assessing MDI-S technique, we surveyed pediatric providers (n = 114) at an inner-city academic medical center. While 82% of providers demonstrated MDI-S technique, only 5% of providers demonstrate the technique at every visit. Although 67% of providers assessed MDI-S technique, only 13% assess the technique at every visit. None of the providers used MDI-S checklist for assessment. Attendings were more likely than residents to demonstrate with illustrations (24% vs 6%, P = .01) and when patient’s asthma was not well controlled (68% vs 47%, P = .05). Provider-identified barriers included limited access to MDI-S device, lack of time, and inadequate knowledge. Suggestions to address barriers include in-service training, device access, and nurse/health educators to alleviate the time constraints. Clinic modifications and education are needed.
