Effects of educational interventions on the smoking cessation service provided by community pharmacists: A systematic review

Objective: This systematic review aimed to evaluate the effectiveness of educational interventions on the smoking cessation service provided by community pharmacists.Methods: A systematic literature search was performed in May-July 2021, in electronic databases, which included PubMed (MEDLINE), Embase, and Web of Science. Studies were included in this systematic review if they were original articles published in English language from 2010 to 2021 and evaluated the effect of any types of educational interventions intended to improve the ability of community pharmacists to provide smoking cessation services.Results: In total, 12 studies were included for this systematic review. The effectiveness of the educational in-terventions across the included studies was measured using a range of outcomes, which can be broadly cate-gorized into 3 categories, namely changes in pharmacists' self-efficacy, knowledge, and attitude toward providing smoking cessation service, changes in pharmacists' smoking cessation practices, and changes in the effectiveness of community pharmacy based smoking cessation services. Included studies reported that educa-tional interventions can improve pharmacists' self-efficacy, knowledge, and attitude toward smoking cessation, as well as pharmacists' smoking cessation practices. Though the evidence is limited, improvement in the effectiveness of community pharmacy based smoking cessation services has also been observed.Conclusion: Any form educational interventions can positively impact improve community pharmacists' self-efficacy, knowledge, and attitude toward smoking cessation, as well as pharmacists' smoking cessation prac-tices, but it is currently uncertain whether these outcomes are able to translate into higher effectiveness of the community pharmacy based smoking cessation services.
