Background Inhalation therapy is the cornerstone for asthma management, and it has been reported by several studies that a correct inhalation technique is required for achievement of proper disease control. Objective This study attempted to assess the inhaler technique in Egyptian children with asthma, identify the factors affecting improper technique, and evaluate the effect of educational intervention in improving the technique and asthma control. Patients and methods This pre–post clinical trial included a random sample of 350 asthmatic children aged 2–12 years, following up at the Allergy Clinic, Faculty of Medicine, Cairo University. They were diagnosed as having asthma according to GINA guidelines and were on inhaled corticosteroids using metered-dose inhaler (MDI) or dry-powder inhaler (DPI) for at least 3 months. Children’s inhalation technique was observed and assessed by the study researcher formerly, and then educational intervention was given, which was then followed by reassessment during the next follow-up visit, and the patient’s level of control was determined during each visit. The study was carried out from 30 June to 31 December 2018. Results Longer duration of inhaler use, regular follow-up, maternal education, and receiving education from a qualified trainer were significantly associated with a proper educational technique (P<0.001). Patients with correct inhalation technique were found to be more controlled compared with incorrect users (P<0.001). The most frequent incorrect step for children using a MDI with spacer was shaking the inhaler, MDI without spacer was coordinating the actuation-slow deep inhalation (53.8%), and DPI was loading the dose properly before each use (65%). After educational training, significant improvement for most of the steps was found (P<0.001) and a significant better asthma control was reached (P<0.001). Conclusion Repeated education, checking, and correction of the inhaler steps are required to reach a proper reliable inhalation technique and better asthma control.
