    Abstract:

    Background: Asthma is rapidly increasing globally. Inhalation therapy is the backbone for asthma management due to localized delivery and rapid onset of action. Currently, metered dose inhalers (MDIs) are the most widely prescribed and dispensed inhaler devices worldwide due to the advantage of portability, multiple dose delivery and better efficacy. Objectives: The current study aimed to access the effect of educational intervention on asthma patients’ competency regarding pressurized metered dose inhaler (pMDI) technique. Methods: Asthma patients were recruited from Pakistan Institute of Medical Sciences (PIMS) Islamabad, Pakistan. Inhaler technique steps based upon “National Asthma Education and Preventive Program” (NAEPP) criteria was set as evaluating tool to evaluate competency of asthma patients regarding MDI appropriate technique. Intervention involved educating study subjects (asthma patients) practically through placebo inhaler and theoretically through inhaler technique directed literature brochures. Pre intervention and post intervention inhaler technique competency was accessed and evaluated statistically. Results: Among 207 asthma patients, majority were never instructed by healthcare professional regarding inhaler technique (78.8%). However, most of the patients were observed to have inadequate inhaler technique (76.3%) at baseline. As the result of educational intervention, the competency of patients regarding inhaler technique was significantly enhanced from 11.6% pre-intervention to 34.8% post-intervention (p<0.001), statistically analyzed by McNemar testing. Conclusion: Originally, inhaler technique competency of majority of asthma patients was observed to be inappropriate. However, educational intervention proved to be effective in substantially enhancing the competency of study subjects regarding MDI technique.
