Theoretical and Practical Knowledge of Metered-Dose Inhalers and Spacer Device Among Health Care Providers in Riyadh,Saudi Arabia

Objective. To assess the theoretical and practical knowledge of health care providers (HCPs) in relation to the use of metered-dose inhalers (MDIs) and spacer devices. Methods. A cross-sectional study was conducted in Riyadh, Saudi Arabia, among 52 HCPs using a stratified random sampling technique. A questionnaire was used to assess theoretical knowledge; practical knowledge was assessed by direct demonstration of the use of an MDI and a spacer device. Results. Among the participants, 57% were female. The majority provided education to their patients (92%). Of the HCPs, 36.5% completed the demonstration of holding the spacer with a mask and MDI together and then shaking well 4 to 5 times, 78.8% completed the demonstration of cap removal, 15.4% completed the demonstration of checking for any foreign body in the spacer, 78.8% completed the demonstration of holding the device properly, 69.2% completed the demonstration of inhaling slowly and deeply, 55.8% completed the demonstration of maintaining the seal for 5 to 6 breaths after the MDI is pressed, 26.9% completed the demonstration of “if more puffs of medication are prescribed, complete these puffs,” and 25% completed the demonstration of washing the spacer with warm soapy water. The overall scores were good (16.6%), fair (44.4%), and poor (39%). Conclusion. Most of the HCPs in this study lacked basic knowledge and skills regarding the proper way to instruct their patients to use MDIs and spacer devices. There is a need to establish continuing education programs for HCPs about asthma inhaler knowledge and technique.
