Objectives: The objective of the study was to find clinically significant evidence on the effectiveness of the intervention in improving inhalation technique in patients with asthma. Materials and methods: The basis of the research is the Cochrane systematic review "Interventions to improve inhaler technique for people with asthma (Review)". MEDLINE and CENTRAL databases were searched to find more recent randomized controlled trials and systematic reviews published after the original Cochrane systematic review. The quality assessment of the Cochrane systematic review "Interventions to improve inhaler technique for people with asthma (Review)", as well as other included systematic reviews, was done using the AMSTAR-2 quality assessment form. Results: In addition to the Cochrane systematic review, 19 additional randomized controlled trials and 5 systematic reviews were found, with meta-analyses conducted in two of the systematic reviews. Across all of these studies, the results consistently showed that any type of intervention can enhance the accuracy of inhalation technique. However, due to variations in measurement methods for final outcomes, it is not possible to quantify the superiority of one type of education over another. Conclusion: Any form of patient education regarding the proper use of inhalers can lead to improved accuracy in inhalation techniques. Beyond teaching the patient the correct inhalation technique, it is equally crucial to ensure the retention of this knowledge. Given the diverse methods used to assess the effectiveness of different education types and the challenges posed by financial, time, and space constraints in pharmacies, there is no one-sizefits-all approach to enhancing inhalation techniques.
