Peer providers and linkage with buprenorphine care after hospitalization: A retrospective cohort study

The role of recovery peer navigators in retention in outpatient buprenorphine treatment: a retrospective cohort study

BACKGROUND

Racial and ethnic disparities are evident in the accessibility of treatment for opioid use disorder (OUD). Even when medications for OUD (MOUD) are accessible, racially and ethnically minoritized groups have higher attrition rates from treatment. Existing literature has primarily identified the specific racial and ethnic groups affected by these disparities, but has not thoroughly examined interventions to address this gap. Recovery peer navigators (RPNs) have been shown to improve access and overall retention on MOUD.

PATIENTS AND METHODS

In this retrospective cohort study, we evaluate the role of RPNs on patient retention in clinical care at an outpatient program in a racially and ethnically diverse urban community. Charts were reviewed of new patients seen from January 1, 2019 through December 31, 2019. Sociodemographic and clinical visit data, including which providers and services were utilized, were collected, and the primary outcome of interest was continuous retention in care. Bivariate analysis was done to test for statistically significant associations between variables by racial/ethnic group and continuous retention in care using Student's t-test or Pearson's chi-square test. Variables with p value ≤0.10 were included in a multivariable regression model.

RESULTS

A total of 131 new patients were included in the study. RPNs improved continuous retention in all-group analysis (27.6% pre-RPN compared to 80.2% post-RPN). Improvements in continuous retention were observed in all racial/ethnic subgroups but were statistically significant in the non-Hispanic Black (NHB) group (p < 0.001). Among NHB, increases in continuous retention were observed post-RPN in patients with male sex (p < 0.001), public health insurance (p < 0.001), additional substance use (p < 0.001), medical comorbidities (p < 0.001), psychiatric comorbidities (p = 0.001), and unstable housing (p = 0.005). Multivariate logistic regression demonstrated that patients who lacked insurance had lower odds of continuous retention compared to patients with public insurance (aOR = 0.17, 95% CI 0.039-0.70, p = 0.015).

CONCLUSIONS

RPNs can improve clinical retention for patients with OUD, particularly for individuals experiencing several sociodemographic and clinical factors that are typically correlated with discontinuation of care.

Expert Panel Consensus on the Effectiveness and Implementation of Models to Support Posthospitalization Care Transitions for People With Substance Use Disorders

OBJECTIVES

Hospitals are increasingly offering treatment for substance use disorders (SUDs) during medical admissions. However, there is a lack of consensus on the best approach to facilitating a successful transition to long-term medical and SUD care after hospitalization. We aimed to establish a hierarchy of existing SUD care transition models in 2 categories-effectiveness and implementation-using an expert consensus approach.

METHODS

We conducted a modified online Delphi study that convened 25 interdisciplinary clinicians with experience facilitating posthospitalization care transitions for patients with SUD. Panelists rated 10 prespecified posthospitalization care transition models according to 6 criteria concerning each model's anticipated effectiveness (eg, linkage to care, treatment retention) and implementation (eg, feasibility, acceptability). Ratings were made on a 9-point bidirectional scale. Group consensus was determined using the interpercentile range adjusted for symmetry.

RESULTS

After 3 rounds of the Delphi process (96% retention across all 3 rounds), consensus was reached on all 60 rating criteria. Interdisciplinary addiction consult teams (ACTs) and in-reach from partnering outpatient clinics were rated highest for effectiveness. Interdisciplinary ACTs and bridge clinics were rated highest for implementation. Screening, brief intervention, and referral to treatment; protocol implementation; and postdischarge outreach received the lowest ratings overall. Feasibility of implementation was perceived as the largest challenge for all highly rated models.

CONCLUSIONS

An expert consensus approach including diverse clinician stakeholders found that interdisciplinary ACT, in-reach from partnering outpatient clinics, and bridge clinics had the greatest potential to enhance posthospitalization care transitions for patients with SUD when considering both perceived effectiveness and implementation.

Using the Delphi Process to Prioritize an Agenda for Care Transition Research for Patients With Substance Use Disorders

Medical hospitalizations are increasingly recognized as important opportunities to engage individuals with substance use disorders (SUD) and offer treatment. While a growing number of hospitals have instituted interventions to support the provision of SUD care during medical admissions, post-hospitalization transitions of care remain a challenge for patients and clinicians and an understudied area of SUD care. Evidence is lacking on the most effective and feasible models of care to improve post-hospitalization care transitions for people with SUD. In the absence of strong empirical evidence to guide practice and policy, consensus-based research methods such as the Delphi process can play an important role in efficiently prioritizing existing models of care for future study and implementation. We conducted a Delphi study that convened a group of 25 national interdisciplinary experts with direct clinical experience facilitating post-hospitalization care transitions for people with SUD. Our panelists rated 10 existing care transition models according to anticipated effectiveness and facility of implementation based on the GRADE Evidence to Decision framework. Qualitative data on each care model were also gathered through comments and an online moderated discussion board. Our results help establish a hierarchy of SUD care transition models to inform future study and program development.

Caring for Hospitalized Adults With Opioid Use Disorder in the Era of Fentanyl: A Review

Importance

The rise of fentanyl and other high-potency synthetic opioids across US and Canada has been associated with increasing hospitalizations and unprecedented overdose deaths. Hospitalization is a critical touchpoint to engage patients and offer life-saving opioid use disorder (OUD) care when admitted for OUD or other medical conditions.

Observations

Clinical best practices include managing acute withdrawal and pain, initiating medication for OUD, integrating harm reduction principles and practices, addressing in-hospital substance use, and supporting hospital-to-community care transitions. Fentanyl complicates hospital OUD care. Fentanyl's high potency intensifies pain, withdrawal, and cravings and increases the risk for overdose and other harms. Fentanyl's unique pharmacology has rendered traditional techniques for managing opioid withdrawal and initiating buprenorphine and methadone inadequate for some patients, necessitating novel strategies. Further, co-use of opioids with stimulants drugs is common, and the opioid supply is unpredictable and can be contaminated with benzodiazepines, xylazine, and other substances. To address these challenges, clinicians are increasingly relying on emerging practices, such as low-dose buprenorphine initiation with opioid continuation, rapid methadone titration, and the use of alternative opioid agonists. Hospitals must also reconsider conventional approaches to in-hospital substance use and expand clinicians' understanding and embrace of harm reduction, which is a philosophy and set of practical strategies that supports people who use drugs to be safer and healthier without judgment, coercion, or discrimination. Hospital-to-community care transitions should ensure uninterrupted access to OUD care after discharge, which requires special consideration and coordination. Finally, improving hospital-based addiction care requires dedicated infrastructure and expertise. Preparing hospitals across the US and Canada to deliver OUD best practices requires investments in clinical champions, staff education, leadership commitment, community partnerships, quality metrics, and financing.

Conclusions and Relevance

The findings of this review indicate that fentanyl creates increased urgency and new challenges for hospital OUD care. Hospital clinicians and systems have a central role in addressing the current drug crisis.

Emergency Department Peer Support Program and Patient Outcomes After Opioid Overdose

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 12 046 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.

Evaluation of a Primary Care-Based Multidisciplinary Transition Clinic for Patients Newly Initiated on Buprenorphine in the Emergency Department

BACKGROUND

Care transitions represent vulnerable events for patients newly initiating medications for opioid use disorder (MOUD). Multidisciplinary primary care-based transition clinics may improve care linkage and retention in MOUD treatment. Additionally, these interventions may help primary care clinicians (PCPs) overcome barriers to adopting MOUD into practice. In this evaluation, we assessed the impact of a primary care-based transition clinic for patients newly initiating buprenorphine for opioid use disorder (OUD) in the emergency department.

METHODS

We conducted a retrospective program evaluation within a single academic health system involving adults who newly initiated buprenorphine for OUD through an emergency department-based program and were referred to follow up in either a dedicated multidisciplinary primary care-based transition clinic (SPARC) vs referral to usual primary care (UPC). We performed descriptive analyses comparing patient demographics, referral volume, linkage to care, treatment retention, and markers of high-quality care between the 2 groups. A log-rank test was used to determine the difference in probabilities of retention between SPARC and UPC over 6 months.

RESULTS

Over 12 months, the number of referrals to SPARC was greater than to UPC (N = 64 vs N = 26). About 58% of patients referred to SPARC attended an initial visit vs 38% referred to UPC. Treatment retention was consistently greater in SPARC than UPC (1 m: 90% vs 60%; 3 m: 76% vs 40%; 6 m: 60% vs 30%). Markers of care quality including naloxone provision (100% vs 80%) and infectious screening (81% vs 40%) were greater in SPARC clinic. SPARC was associated with a statistically significant increased probability of retention in treatment as compared to UPC (P < .01).

CONCLUSIONS

In this observational evaluation, a primary care-based multidisciplinary transition clinic for patients initiating buprenorphine MOUD was associated with expanded access to longitudinal OUD treatment and superior linkage to care, retention in care, and quality of care compared to referral to usual primary care. Further research using a more rigorous research design is required to further evaluate these findings.
