Non-Inferiority of Online Compared With In-Person Opioid Overdose Prevention Training in Medical Students

Abstract

Background:

Drug overdose deaths have increased fivefold over the last 20 years, primarily fueled by synthetic opioids, which led the Centers for Disease Control and Prevention to declare an opioid overdose epidemic. Responding to this epidemic, we designed and implemented opioid overdose prevention (OOP) training for medical students to help promote effective naloxone usage. Previously, we compared online and in-person versions of OOP training over 2 years of training. To better establish the evidence for online training, we performed a randomized controlled non-inferiority trial comparing in-person with online opioid prevention training.

Methods:

Third-year medical students were randomized into groups to receive either in-person or online training in preparation for clinical rotations. Students randomized to receive online training were provided a link to the training modules. Students randomized to receive in-person training were trained in an in-person setting. We performed a non-inferiority per-protocol analysis with the primary outcome of knowledge using a non-inferiority margin of a −9.1% difference between groups.

Results:

A total of 205 students were randomized, 103 students to in-person training and 102 to online training. Eighty-three in-person students and 104 online students were included. The online group had a higher post-training knowledge score compared to the in-person group by 0.44 points (0-11 point scale) with a 95% CI of (−0.04, 0.93) that did not cross the margin of non-inferiority.

Conclusions:

Online training for OOP was effective and non-inferior to in-person training. Online OOP training may be considered an alternative to in-person training.
