Temporal Reinforcement of Naloxone Training Results in Significant Retention of Anti-bias and Overdose-Response Knowledge.

Abstract

The opioid epidemic is an increasingly severe problem affecting public health and leading to significant economic burdens on healthcare systems. Overdose reversal training and de-stigmatization efforts are common strategies used to combat this epidemic.Nevertheless, healthcare professionals report a lack of confidence in administering naloxone and high stigmatization levels towardpeople with opioid use disorder (OUD).While one-time educational training reduces stigma and improves naloxone administration confidence, we previously demonstrated that knowledge retention at a three-month follow-up is reduced amonga cohort of medical students. This study aimed to improve the effectiveness of opioid overdose awareness and reversal training (OOART) with a three-month follow-up abbreviated OOART (aOOART) booster video. Voluntary OOART was offered to first-year medical students (M1) at the Drexel University College of Medicine in 2022.At this training, 82 students completed a pre-training survey to establish a baseline knowledge and attitude towardpeople with OUD and their familiarity with the steps to reverse an opioid overdose. Following the hour-long training, 64 of 82 (79%) participants completed the post-training survey to measure the immediate retention of training information. After 2.5 months, students were randomly selected to receive a 6.5-minute aOOART booster video or serve as an unboosted control. Students in the booster and non-booster cohorts then completed a three-month follow-up survey. Students who received the aOOART booster had significantly increased opioid reversal knowledge scores compared to non-boosted control students at the three-month follow-up.The aOOART booster resulted in a retention of the lowered stigma, and participants expressed a higher willingness to respond to an opioid overdose compared to participants who did not receive the booster video at the three-month follow-up. This study shows that an aOOART booster method improves knowledge retention following initial OOART.Further, the aOOART booster video served to maintain participants' reduced stigma towardpeople with OUD and maintained participants' willingness to respond to an opioid overdose.These results support the incorporation of an abbreviated, periodic OOART reinforcement video into opioid overdose response training nationwide. We believe this "booster video" approach is a novel and effective method to improve healthcare professionals' and medical student preparedness to render appropriate care to people with OUD.
