OBJECTIVES/GOALS: People experiencing homelessness vs. housed peers have higher rates of substance use disorders as well as increased emergency medical services (EMS) use. However, it is unknown if EMS administers naloxone at different rates to people experiencing homelessness. We address if patient housing status impacts naloxone administration by EMS providers. METHODS/STUDY POPULATION: We conducted a retrospective, cross-sectional analysis of electronic patient care reports (ePCRs) for all 911-incidents attended by the Los Angeles Fire Department (LAFD) during the study period, January to December 2018. Individuals who were medically assessed by the LAFD and who were administered naloxone by LAFD EMS were included. Exclusion criteria was incomplete ePCRs. The primary outcome was prevalence of EMS naloxone administration by housing status in the city of Los Angeles. We used descriptive statistics and a logistic regression model to examine differences in care. RESULTS/ANTICIPATED RESULTS: Naloxone was administered in 2,438 of the 345,190 incidents that occurred during the study period. 608 (25%) incidents involved people experiencing homelessness. Top indications for naloxone administration were similar in both groups: overdose, altered consciousness and cardiac arrest. Of those who received naloxone, people experiencing homelessness were more likely to be male (82% v 67%) and younger (41 v 46 years). People experiencing homelessness were more likely to receive naloxone (OR 2.6, 95% CI 2.4-2.9). People experiencing homelessness received naloxone at a rate of 44 times that of housed peers. A logistic regression model adjusting for gender, age, respiratory depression and transport status showed people experiencing homelessness remained more likely to receive naloxone (OR 2.3, 95% CI 2.0-2.5). DISCUSSION/SIGNIFICANCE: Emergency medical services are more likely to administer naloxone to people experiencing homelessness than housed peers. There is a need to identify bias and factors that impact prehospital care and patient outcomes of people experiencing homelessness. New care pathways for people confronting homelessness and opioid use disorders are needed.
