Nudging Emergency Department-Initiated Addiction Treatment.

OBJECTIVES: When initiated in the Emergency Department (ED), medication for addiction treatment (MAT) with buprenorphine improves outcomes, increases engagement in addiction treatment and decreases the use of inpatient addiction treatment services. Unfortunately, initiating MAT in the ED is not yet standard practice. We assessed the impact of the addition of a multipart behavioral science-based intervention to increase opioid use disorder (OUD)-related treatments prescribed in the ED. METHODS: Our ED initiated a campaign to help ED faculty obtain their DEA-X waiver required to prescribe buprenorphine. In parallel, we implemented 2 ED-initiated buprenorphine treatment pathways. We then conducted a two-stage qualitative process informed by behavioral science to identify key barriers to physician use of the MAT protocol. Using these insights, we developed 4 behavioral science-based interventions. To assess the impact of the interventions on the number of OUD-related treatments per day among patients meeting the inclusion criteria we compared the number of OUD-related treatments per day before versus after the interventions began using t tests. Then, in our primary model, we estimated the causal effect of the behavioral interventions using a regression discontinuity in time approach. RESULTS: Across the entire year study period, there is an increase in OUD-related treatment after the interventions begin, driven by greater use of ambulatory referral orders. The unadjusted mean difference in any OUD treatments per day pre- versus post-intervention increased by 0.80 (95% confidence interval [CI]: 0.04, 1.56; P = 0.039) whereas the number of ambulatory referral orders placed increased by 0.82 (95% CI: 0.48,1.16; P < 0.001). Using the 120-day study window and an ordinary least squares regression discontinuity in time model, the 4-part intervention increased the number of patients receiving any opioid treatment in the ED by 1.6 additional treatments per day (95% CI: 0.04, 3.19; P = 0.045). CONCLUSIONS: To support our protocol and increase the provision of ED-MAT, we implemented 1 patient-facing and 3 provider-facing interventions rooted in behavioral science principles. Our results show that this pack of behavioral science interventions increased the likelihood that ED providers offer MAT to patients with OUD.

Beyond Buprenorphine: Models of Follow-up Care for Opioid Use Disorder in the Emergeny Department.

Recent evidence shows that emergency physicians (EP) can help patients obtain evidence-based treatment for Opioid Use Disorder by starting medication for addiction treatment (MAT) directly in the Emergency Department (ED). Many EDs struggle to provide options for maintenance treatment once patients are discharged from the ED. Health systems around the country are in need of a care delivery structure to link ED patients with OUD to care following initiation of buprenorphine. This paper reviews the three most common approaches to form effective partnerships between EDs and primary care/addiction medicine services: the Project Alcohol and Substance Abuse Services and Referral to Treatment (ASSERT) model, Bridge model, and ED-Bridge model.The ASSERT Model is characterized by peer educators or community workers in the ED directly referring patients suffering from OUD in the ED to local addiction treatment services. The Bridge model encourages prescribing physicians in an ED to screen patients for OUD, provide a short-term prescription for buprenorphine, and then refer the patient directly to an outpatient Bridge Clinic that is co-located in the same hospital but is a separate from the ED. This Bridge Clinic is staffed by addiction trained physicians and mid-level clinicians. The ED-Bridge model employs physicians trained in both emergency medicine and addiction medicine to serve within the ED as well as in the follow up addiction clinic.Distinct from the Bridge Clinic model above, EPs in the ED-Bridge model are both able to screen at-risk patients in the ED, often starting treatment, and to longitudinally follow patients in a regularly scheduled addiction clinic. This paper provides examples of these three models as well as implementation and logistical details to support a health system to better address OUD in their communities.
