Objective

The objective of this study was to estimate the association between receipt of specific post-overdose care services in the emergency department (ED) and subsequent engagement in treatment for opioid use disorder (OUD) after discharge.

Methods

This was a retrospective cohort study of Rhode Island residents treated at 1 of 4 EDs for opioid overdose who were not engaged in OUD treatment and were discharged home (May 2016-April 2021). Electronic health record data were used to identify ED services received, and state administrative data were used to define subsequent engagement in OUD treatment within 30 days. Multivariable conditional logistic regression was used to estimate the association between ED services received and subsequent treatment engagement.

Results

Overall, 1008 people not engaged in OUD treatment were treated at study EDs for opioid overdose and discharged home, of whom 146 (14%) subsequently engaged in OUD treatment within 30 days. Most patients were aged 25 to 44 years (59%) and non-Hispanic White (69%). Receipt of behavioral counseling in the ED (adjusted odds ratio [aOR] = 1.79, 95% confidence interval [CI] = 1.18-2.71) and initiation of buprenorphine treatment in/from the ED (aOR = 5.86, 95% CI = 2.70-12.71) were associated with treatment engagement. Receipt of a take-home naloxone kit or naloxone prescription and referral to treatment at discharge were not associated with treatment engagement. Overall, 49% of patients received behavioral counseling in the ED, and 3% initiated buprenorphine in/from the ED.

Conclusion

Strategies for increasing provision of behavioral counseling and initiation of buprenorphine in the ED may be useful for improving subsequent engagement in OUD treatment after discharge.

OBJECTIVE: To evaluate the impact of a statewide treatment standards policy for post-overdose emergency department (ED) care on services provided and subsequent treatment engagement. METHODS: This pre-/post-study used electronic health record data and surveillance data from Rhode Island. Outcomes were compared for patients attending EDs for opioid overdose before (03/1/2015-02/28/2017) and after (04/01/2017-03/31/2021) policy release. RESULTS: Overall, 2,134 patients attended 2,891 ED visits for opioid overdose. Compared to pre-policy, visits post-policy more often included initiation of buprenorphine in or from the ED (<1% vs. 3%, p<0.01), provision of a take-home naloxone kit or prescription (41% vs. 58%, p<0.01), and referral to treatment (0% vs. 34%, p<0.01). Provision of behavioral counseling in the ED and initiation of treatment within 30 days of the visit were similar during the two periods. CONCLUSIONS: Statewide post-overdose treatment standards may improve provision of some ED services. Additional strategies are needed to improve subsequent treatment engagement.
