Background: Asthma is a heterogeneous disease which is characterized by chronic airway inflammation. It is an affecting 1-18% of the population in different countries. It can be treated mainly with inhaled medications in several forms, including the pressurized Metered-Dose Inhaler (MDI). MDI use can, unfortunately, be difficult for patients to use and even with repeated demonstration and some patients will still find co-ordination of the whole technique challenging, failing to master it despite repeated demonstration. Objective: To evaluate the effect of the intervention on MDI use technique among adult asthmatic patients who attend a respiratory clinic in Jimma University Medical Center (JUMC), Southwest Ethiopia. Method: The interventional study was conducted from March-August 22/2018. All adult asthmatic patients who met inclusion criteria were included in the study. Patient baseline assessment was conducted (patient demography, inhalation technique, adherence, and asthma control status). The baseline inhalation technique was obtained using a standard check-list of recommended steps National Institute of Health (NIH) guidelines. After the intervention, inhalation technique was re-evaluated. Independent predictors of outcome identified and strength of association between dependent and independent variables determined by using binary logistic regression analysis and statistical significance was considered at p < 0.05. McNemar test was used to compare the pre-, post-result of the inhalation technique. Results: One hundred forty patients were included in the analysis. The most frequent critical step mistake in both preand post-intervention was the short duration of the inhalation 87.1%. At the first visit, 121 (86.4%, 95% CI: 81-92) patients were inefficient and it was dropped to 103 (73.57%, 95% CI: 66-81) after the intervention. The mean critical error was 2.69 in pre-intervention and dropped to 2.09 after an intervention. Before the intervention, 18 (12.9%) patients were controlled and increased to 26 (18.4%) after intervention. Conclusion: Most of the study participants were inefficient before the intervention. After the intervention, the number of patients who were efficient is increased as compared to pre-intervention and found to be highly significant in the inhalation technique. The Hospital tries to adopt the video MDI teaching program and the patient should ask health care professional show to take medication and they should bring their device to receive a demonstration during the visit. Health professionals should re-evaluate the patient during their Hospital visit and encourage them to bring their device to give a demonstration.
