Imperative Instruction for Pressurized Metered-Dose Inhalers: Provider Perspectives

Area of Science:

• Pediatric primary care
• Respiratory medicine
• Health services research

Background:

• Effective pressurized metered-dose inhaler (pMDI) use is crucial for managing asthma.
• Current data are limited on how pediatric primary care providers assess and teach pMDI technique.
• National guidelines recommend regular patient education and technique assessment.

Purpose of the Study:

• To identify instructional methods for pMDI use in pediatric primary care.
• To describe the frequency and methods of pMDI technique reassessment.
• To understand provider attitudes and barriers to in-office pMDI instruction.

Main Methods:

• An electronic survey was distributed to pediatric primary care providers.
• The survey assessed pMDI teaching methods, reassessment practices, and barriers.
• Descriptive statistics were used for data analysis.

Main Results:

• Only 28% of surveyed providers responded.
• Most pMDI education is provided by physicians and nurse practitioners.
• Few providers ensure patient practice with feedback (10%) or consistently reassess technique (19%).
• Verbal reassessment (76%) and lack of demonstration (42%) were common.
• Time (84%) and lack of demo inhalers (67%) were key barriers.

Conclusions:

• Pediatric primary care providers often fail to ensure patients practice pMDI use and reassess technique infrequently.
• Barriers such as time and equipment access hinder effective pMDI education.
• Implementing consistent educators (e.g., respiratory therapists) and providing demo inhalers may improve pMDI technique mastery.
