RESUMEN
Importance: Patients treated in emergency departments (EDs) for opioid overdose often need drug treatment yet are rarely linked to services after discharge. Emergency department-based peer support is a promising approach for promoting treatment linkage, but evidence of its effectiveness is lacking. Objective: To examine the association of the Opioid Overdose Recovery Program (OORP), an ED peer recovery support service, with postdischarge addiction treatment initiation, repeat overdose, and acute care utilization. Design, Setting, and Participants: This intention-to-treat retrospective cohort study used 2014 to 2020 New Jersey Medicaid data for Medicaid enrollees aged 18 to 64 years who were treated for nonfatal opioid overdose from January 2015 to June 2020 at 70 New Jersey acute care hospitals. Data were analyzed from August 2022 to November 2023. Exposure: Hospital OORP implementation. Main Outcomes and Measures: The primary outcome was medication for opioid use disorder (MOUD) initiation within 60 days of discharge. Secondary outcomes included psychosocial treatment initiation, medically treated drug overdoses, and all-cause acute care visits after discharge. An event study design was used to compare 180-day outcomes between patients treated in OORP hospitals and those treated in non-OORP hospitals. Analyses adjusted for patient demographics, comorbidities, and prior service use and for community-level sociodemographics and drug treatment access. Results: A total of 12â¯046 individuals were included in the study (62.0% male). Preimplementation outcome trends were similar for patients treated in OORP and non-OORP hospitals. Implementation of the OORP was associated with an increase of 0.034 (95% CI, 0.004-0.064) in the probability of 60-day MOUD initiation in the half-year after implementation, representing a 45% increase above the preimplementation mean probability of 0.075 (95% CI, 0.066-0.084). Program implementation was associated with fewer repeat medically treated overdoses 4 half-years (-0.086; 95% CI, -0.154 to -0.018) and 5 half-years (-0.106; 95% CI, -0.184 to -0.028) after implementation. Results differed slightly depending on the reference period used, and hospital-specific models showed substantial heterogeneity in program outcomes across facilities. Conclusions and Relevance: In this cohort study of patients treated for opioid overdose, OORP implementation was associated with an increase in MOUD initiation and a decrease in repeat medically treated overdoses. The large variation in outcomes across hospitals suggests that treatment effects were heterogeneous and may depend on factors such as implementation success, program embeddedness, and availability of other hospital- and community-based OUD services.

BACKGROUND: Peer recovery programs increase recovery support and treatment engagement among individuals with opioid use disorder. Peer recovery specialists (PRS) are critical in the cascade of care of treating addiction and related conditions. Work remains to help identify the benefits of PRS, particularly time spent with a PRS as a clinical indicator associated with referral to substance use treatment services. Gaps in the literature do not consider the nested hierarchical intercorrelations of opioid recovery data within multiple emergency departments. PURPOSE: The current study examined demographic and clinical correlates with referral to substance use treatment services including prior engagement within an opioid overdose recovery program, mental health diagnosis, the number of naloxone administrations, prior overdoses, and hospital-level variability of PRS time associated with treatment referrals. METHOD: This study used data collected by providers among patients who engaged in an opioid overdose recovery program. Data were collected between January 2016 and September 2020. Generalized linear mixed effect multilevel regression analyses tested the associations on clinical referral to substance use services. RESULTS: A total of 5655 patients participated in the study (male: 68.91%; age: mean = 37.75 ± 12.43; White non-Hispanic: 62.48%). Significant individual-level associations were identified between demographic and clinical variables and referral to substance use treatment services. At the hospital level, recovery specialist time spent with the patient also showed a positive and significant association with referral to substance use treatment services. CONCLUSION: The cross-level interaction effect displayed that any period of time spent with PRS played an important role for those patients with a greater number of prior overdoses on referral to treatment. Results provide important information on the role of PRS in the cascade of care, as well as the time spent with those in this role for both individuals with varying number of prior overdoses.
