BackgroundAntimicrobial resistance has always been an important issue as antimicrobial therapies are becoming less effective due to incorrect use and overuse. Our objective was to evaluate the impact of social media education on spreading antimicrobial stewardship awareness among healthcare students and residents.MethodsA prospective interventional study was conducted over 5 months, from November 2021 until March 2022. Weekly educational posts on infectious diseases were posted along with pre- and post- quizzes on a designated Facebook page. The primary endpoint of change in knowledge score was assessed using the independent t-test. Expected average pre-training is 2.5 over 5, and the expected average post-training is a minimum of 3.5 over 5 (common standard deviation of 1) for a minimum of 20% improvement that produces an effect size d = 1. Expecting a larger number of respondents on the pre-test than post-test, the ratio N1/N2 was set to 1.5. With the desired power set to 80% and alpha at 5%, sample size was determined as a minimum of 22 (N1) and 14 (N2). All analyses were carried at the 0.05 significance level.ResultsIn the entry questionnaire, 85.6% (107/125) of participants believed that antibiotics are overused, 26.4% (33/125) confirmed that they overuse antibiotics, and 88.8% (111/125) confirmed the importance of having an antimicrobial stewardship program. 76.8% (96/125) of the participants regularly use social media for educational purposes and only 2.4% sometimes refer to social media as an educational tool. Improvement in knowledge was noted in all pre and post – quizzes except for two quizzes (prostatitis and acute cystitis – 18.4% and 13.2% improvement respectively). In total, there was a significant 36.2% improvement between all pre and post quizzes [min 13.2% and max 52.8% across all quizzes].ConclusionThis intervention demonstrated the importance of social media as a valuable tool to enhance antimicrobial stewardship knowledge among pharmacy, medical and nursing students and residents. Future studies are needed to examine the impact of social media education on behaviors in practice.
