Objectives: In response to a surge of drug overdoses involving polysubstance use among Atlanta service industry workers that resulted in the deaths of five people in the Atlanta area in the summer of 2021, a local community of harm reductionists and nurses organized opioid education and naloxone distribution (OEND) training sessions specifically customized for service industry workers in Atlanta. After the sessions, the nurses and harm reductionists asked attendants to participate in a study concerning their response to overdoses. The reason nurses and harm reductionists conducted the study was to determine the efficacy of OEND training adapted for those working in the service industries as well as to evaluate and possibly modify the training sessions for future use. This pre-post study examined if and how participants' knowledge and attitudes toward an opioid-involved overdose changed after engaging with the OEND training. If the study determined that the sessions were successful in teaching service industry workers how to mitigate the immediate and devastating effects of overdose, we recommend expanding and implementing both adaptable training sessions like the OEND training referenced, as well as accompanying studies to improve the training sessions' effectiveness. Design: The pre-post study used convenience sampling to recruit participants in emergent OEND training. Participants completed an abbreviated version the Opioid Overdose Attitudes Scale (OOAS) which measured how, and to what degree, they changed their attitudes towards overdoses and their responses to them. Participants also completed an abbreviated version of the Opioid Overdose Knowledge Scale (OOKS) which measured how effectively the OEND increased their knowledge when it came to properly responding to an overdose, which included implementing naloxone as part of immediate rehabilitation treatment. Paired nonparametric tests assessed changes in participants' OOAS/OOKS scores.
