MHealth Incentivized Adherence Plus Patient Navigation (MIAPP): protocol for a pilot randomized controlled trial to improve linkage and retention on buprenorphine for hospitalized patients with methamphetamine use and opioid use disorder

BackgroundInitiation of buprenorphine for treatment of opioid use disorder (OUD) in acute care settings improves access and outcomes, however patients who use methamphetamine are less likely to link to ongoing treatment. We describe the intervention and design from a pilot randomized controlled trial of an intervention to increase linkage to and retention in outpatient buprenorphine services for patients with OUD and methamphetamine use who initiate buprenorphine in the hospital.MethodsThe study is a two-arm pilot randomized controlled trial (N = 40) comparing the mHealth Incentivized Adherence Plus Patient Navigation (MIAPP) intervention to treatment as usual. Development of the MIAPP intervention was guided by the information-motivation-behavioral skills model and combines financial rewards via mobile health-based adherence monitoring with the “human touch” of a patient navigator. Participants receive financial incentives for submitting videos of themselves taking buprenorphine via smartphone. The Patient Navigator reviews videos and provides treatment adherence coaching, care coordination and motivational enhancement. The intervention is introduced prior to hospital discharge and is offered for 30 days. The primary outcome is linkage to outpatient buprenorphine care within 30 days of hospital discharge. Secondary outcomes include retention on buprenorphine 90 days post discharge, hospital readmissions, and past 30-day methamphetamine use.DiscussionInterventions are needed to increase linkage and retention to outpatient buprenorphine among hospitalized patients with OUD, especially for people who co-use methamphetamine. We will examine the MIAPP intervention to improve buprenorphine adherence and linkage to outpatient treatment in a pilot randomized controlled trial which will provide valuable insights about research approaches for hospitalized patients with substance use disorder.Trial registration number: NCT06027814.

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.

Treatment setting and buprenorphine discontinuation: an analysis of multi-state insurance claims

BackgroundPotential differences in buprenorphine treatment outcomes across various treatment settings are poorly characterized in multi-state administrative data. We thus evaluated the association of opioid use disorder (OUD) treatment setting and insurance type with risk of buprenorphine discontinuation among commercial insurance and Medicaid enrollees initiated on buprenorphine.MethodsIn this observational, retrospective cohort study using the Merative MarketScan databases (2006–2016), we analyzed buprenorphine retention in 58,200 US adults with OUD. Predictor variables included insurance status (Medicaid vs commercial) and treatment setting, operationalized as substance use disorder (SUD) specialty treatment facility versus outpatient primary care physicians (PCPs) versus outpatient psychiatry, ascertained by linking physician visit codes to buprenorphine prescriptions. Treatment setting was inferred based on timing of prescriber visit claims preceding prescription fills. We estimated time to buprenorphine discontinuation using multivariable cox regression.ResultsAmong enrollees with OUD receiving buprenorphine, 26,168 (45.0%) had prescriptions from SUD facilities without outpatient buprenorphine treatment, with the remaining treated by outpatient PCPs (n = 23,899, 41.1%) and psychiatrists (n = 8133, 13.9%). Overall, 50.6% and 73.3% discontinued treatment at 180 and 365 days respectively. Buprenorphine discontinuation was higher among enrollees receiving prescriptions from SUD facilities (aHR = 1.03[1.01–1.06]) and PCPs (aHR = 1.07[1.05–1.10]). Medicaid enrollees had lower buprenorphine retention than those with commercial insurance, particularly those receiving buprenorphine from SUD facilities and PCPs (aHR = 1.24[1.20–1.29] and aHR = 1.39[1.34–1.45] respectively, relative to comparator group of commercial insurance enrollees receiving buprenorphine from outpatient psychiatry).ConclusionBuprenorphine discontinuation is high across outpatient PCP, psychiatry, and SUD treatment facility settings, with potentially lower treatment retention among Medicaid enrollees receiving care from SUD facilities and PCPs.

Relationship between opioid cross-tolerance during buprenorphine stabilization and return to opioid use during buprenorphine dose tapering.

Opioid injection drug use (IDU) has been linked to a more severe pattern of use (e.g. tolerance, overdose risk) and shorter retention in treatment, which may undermine abstinence attempts. This secondary data analysis of four human laboratory studies investigated whether current opioid IDU modulates subjective abuse liability responses to high-dose hydromorphone during intermediate-dose buprenorphine stabilization (designed to suppress withdrawal but allow surmountable agonist effects), and whether hydromorphone response magnitude predicts latency of return to opioid use during buprenorphine dose-tapering. Regular heroin users not currently seeking treatment (n = 54; 29 current injectors, 25 non-injectors) were stabilized on 8-mg/day sublingual buprenorphine and assessed for subjective responses (e.g. 'liking', craving) to hydromorphone 24-mg intramuscular challenge (administered 16-hr post-buprenorphine) under randomized, double-blinded, controlled conditions. A subgroup (n = 35) subsequently completed a standardized 3-week outpatient buprenorphine dose-taper, paired with opioid-abstinent contingent reinforcement, and were assessed for return to opioid use based on thrice-weekly urinalysis and self-report. During buprenorphine stabilization, IDU reported lower 'liking' of buprenorphine and post-hydromorphone peak 'liking', 'good effect' and 'high' compared to non-IDU. Less hydromorphone peak increase-from-baseline in 'liking' (which correlated with less hydromorphone-induced craving suppression) predicted significantly faster return to opioid use during buprenorphine dose-tapering. In these buprenorphine-stabilized regular heroin users, IDU is associated with attenuated 'liking' response (more cross-tolerance) to buprenorphine and to high-dose hydromorphone challenge and, in turn, this cross-tolerance (but not IDU) predicts faster return to opioid use. Further research should examine mechanisms that link cross-tolerance to treatment response.

Novel Uses of Methadone Under the "72-Hour Rule" to Facilitate Transitions of Care and Low-Dose Buprenorphine Induction in an Outpatient Bridge Clinic.

Federal regulations restrict methadone for opioid use disorder (OUD) treatment to licensed opioid treatment programs (OTPs). However, providers in other settings can administer methadone for opioid withdrawal under the "72-hour rule" while linking to further care. Prior work has demonstrated that methadone initiation in a low-barrier bridge clinic is associated with high OTP linkage and 1-month retention rates. We describe 2 other novel applications of the 72-hour rule in which methadone withdrawal management facilitated linkage to inpatient hospitalization and outpatient buprenorphine induction. Patient 1 was a 46-year-old woman with OUD complicated by serious injection-related infections. Severe opioid withdrawal limited her ability to tolerate emergency department wait times and receive inpatient care. We administered methadone for opioid withdrawal in an outpatient bridge clinic immediately before emergency department referral; this enabled hospital admission for intravenous antibiotics and anticoagulation. Patient 2 was a 36-year-old man with OUD desiring buprenorphine treatment. He had been unable to complete traditional buprenorphine induction without experiencing precipitated withdrawal. Thus, we recommended a low-dose buprenorphine induction overlapping with a full opioid agonist. Given the patient's preference to stop using fentanyl immediately, he received 72 hours of methadone for withdrawal treatment during the induction phase and successfully transitioned to buprenorphine without significant concomitant fentanyl use. In addition to facilitating OTP linkage, on-demand 72-hour methadone administration for opioid withdrawal can reduce barriers to acute medical care and buprenorphine treatment.

How to interpret ‘secret shopper’ studies of residential programs

Many parents want their children — even their adult children — with substance use disorders (SUDs) to be in residential treatment. They feel that it's safe. They don't want them to have outpatient buprenorphine or methadone, despite the fact that these medications are first line treatment for opioid use disorders (OUDs). In addition, many of these children do not have opioid problems — increasingly, stimulants are a problem, and alcohol and marijuana always have been; OUD medications don't work for these SUDs.

Non-overdose acute care hospitalizations for opioid use disorder among commercially-insured adults: a retrospective cohort study

BackgroundAcute care inpatient admissions outside of psychiatric facilities have been increasingly identified as a critical touchpoint for opioid use disorder (OUD) treatment. We sought to describe non-opioid overdose hospitalizations with documented OUD and examine receipt of post-discharge outpatient buprenorphine.MethodsWe examined acute care hospitalizations with an OUD diagnosis in any position within US commercially-insured adults age 18–64 years (IBM MarketScan claims, 2013–2017), excluding opioid overdose diagnoses. We included individuals with ≥ 6 months of continuous enrollment prior to the index hospitalization and ≥ 10 days following discharge. We described demographic and hospitalization characteristics, including outpatient buprenorphine receipt within 10 days of discharge.ResultsMost (87%) hospitalizations with documented OUD did not include opioid overdose. Of 56,717 hospitalizations (49,959 individuals), 56.8% had a primary diagnosis other than OUD, 37.0% had documentation of an alcohol-related diagnosis code, and 5.8% end in a self-directed discharge. Where opioid use disorder was not the primary diagnosis, 36.5% were due to other substance use disorders, and 23.1% were due to psychiatric disorders. Of all non-overdose hospitalizations who had prescription medication insurance coverage and who were discharged to an outpatient setting (n = 49, 237), 8.8% filled an outpatient buprenorphine prescription within 10 days of discharge.ConclusionsNon-overdose OUD hospitalizations often occur with substance use disorders and psychiatric disorders, and very few are followed by timely outpatient buprenorphine. Addressing the OUD treatment gap during hospitalization may include implementing medication for OUD for inpatients with a broad range of diagnoses.

Acute Pain Management in Traumatically Injured Patients With Outpatient Buprenorphine Therapy

IntroductionAcute pain management is challenging in trauma patients undergoing outpatient buprenorphine therapy at the time of injury due to the high binding affinity of this partial agonist. The purpose of this study was to evaluate acute pain management in admitted trauma patients with discontinued versus continued outpatient buprenorphine therapy. Materials and MethodsThis retrospective study included adult trauma patients admitted to a level-1 trauma center between January 2017 and August 2020 who were receiving buprenorphine prior to admission. Groups were defined as buprenorphine discontinued (BD) or continued (BC) during hospitalization. The primary outcome compared median daily morphine milligram equivalents between groups. Secondary outcomes utilized patient-reported numeric rating scale (NRS) scores to compare incidences of no pain (NRS 0), mild (NRS 1-3), moderate (NRS 4-6), and severe (NRS 7-10) pain. ResultsA total of 57 patients were included (BD 37 [64.9%] and BC 20 [35.1%]). The median (interquartile range) outpatient daily buprenorphine dose was similar between groups (8 [8-16] mg versus 16 [8-16], P = 0.25). Median daily morphine milligram equivalents was significantly higher during admission in the BD group (103.7 [80.7-166] versus 67 [30.8-97.4], P = 0.002). Incidence of no pain (7.1% versus 5.7%, P = 0.283), mild (5.5% versus 4.3%, P = 0.295), moderate (20.2%, 19.8%, P = 0.855), or severe (67.2% versus 70.2%, P = 0.185) pain was similar between BD and BC groups, respectively. ConclusionsContinuation of outpatient buprenorphine therapy in acute trauma patients is associated with decreased daily opioid requirements and similar analgesic efficacy compared to patients with BD. Based on our findings, trauma patients receiving outpatient buprenorphine and not requiring ventilator support may benefit from buprenorphine continuation within 48 h of initial presentation.

"Macrodosing" Sublingual Buprenorphine and Extended-release Buprenorphine in a Hospital Setting: 2 Case Reports.

To describe 2 case reports in which high-dose administration of sublingual buprenorphine/naloxone quickly stabilized fentanyl users who presented to the hospital. To discuss how early administration of extended-release buprenorphine, before the patient is discharged, may improve retention rates for outpatient buprenorphine treatment. Two case reports of fentanyl users presented to the emergency department at the general hospital in Timmins, Canada are described. They were rapidly stabilized on high-dose sublingual buprenorphine/naloxone and then transitioned within 24 to 36 hours to buprenorphine extended-release subcutaneous injection. In both cases, their withdrawal symptoms quickly resolved, without sedation or precipitated withdrawal. Both patients followed up with the outpatient clinic for another injection of extended-release buprenorphine. High-dose sublingual buprenorphine/naloxone followed by early administration of extended-release buprenorphine quickly and safely relieved withdrawal symptoms in 2 fentanyl users who presented to the hospital emergency department. This novel approach shows promise in improving treatment retention rates for patients using fentanyl. Further research is required to evaluate the safety and effectiveness of this approach.

Enhancing distress tolerance to uplift motivation in recovery: Results from an open development trial.

This open pilot study examines the feasibility, acceptability, and qualitative outcomes of an interactive web- and text message-delivered personalized feedback intervention aimed at cultivating motivation and tolerance of distress for adults initiating outpatient buprenorphine treatment. Patients (n = 10) initiating buprenorphine within the past 8 weeks first completed a web-based intervention focused on enhancing motivation and providing psychoeducation on distress tolerance skills. Participants then received 8 weeks of daily personalized text messages that provided reminders of salient motivational factors and recommended distress tolerance-oriented coping skills. Participants completed self-report measures to assess intervention satisfaction, perceived usability, and preliminary efficacy. Additional perspectives were captured via qualitative exit interviews. In total, 100% of retained participants (n = 9) engaged with the text messages throughout the entire 8-week period. Mean scores of 27 (SD = 5.05) on the Client Satisfaction Questionnaire at the end of 8-week period indicated a high degree of satisfaction with the text-based intervention. The average rating on the System Usability Scale was 65.3 at the end of the 8-week program, suggesting that the intervention was relatively easy to use. Participants also endorsed positive experiences with the intervention during qualitative interviews. Clinical improvements were observed across the intervention period. Preliminary findings from this pilot suggest that the content and delivery method of this combined web- and text message-based personalized feedback intervention is perceived by patients as feasible and acceptable. Leveraging digital health platforms to augment buprenorphine has potential for high scalability and impact to reduce opioid use, increase adherence/retention to treatment, and prevent future incidence of overdose. Future work will evaluate the efficacy of the intervention in a randomized clinical trial design.

Location of buprenorphine initiation and opioid use disorder treatment outcomes during pregnancy

Opioid use disorder (OUD) is a major contributor to maternal morbidity and mortality, largely during the one-year postpartum period. Medication treatment reduces overdose risk and improves perinatal outcomes. Our study aimed to assess the association of the location of buprenorphine initiation (inpatient versus outpatient) with buprenorphine continuation through one year postpartum among a cohort of pregnant people with OUD. We performed a retrospective cohort study comparing rates of buprenorphine continuation through 52 weeks postpartum among a cohort of pregnant people cared for at an academic medical center (2017 – 2020) where both inpatient and outpatient buprenorphine initiation is offered. Medical record abstractions were conducted in pregnancy through one year postpartum. Exposure of interest was location of buprenorphine initiation (inpatient versus outpatient). Primary outcome was postpartum week of buprenorphine discontinuation. Bivariate analyses, Kaplan Meier survival curves, and Cox Proportional Hazard models were used. Our cohort included 116 patients, 77 initiating buprenorphine inpatient and 39 initiating outpatient. Most were insured by Medicaid (73%), lacked college education (55%), and had comorbid mental health conditions (71%) and substance use disorder (69%). Median gestational age at delivery was 39 weeks (Table 1). Outpatient initiation of buprenorphine during pregnancy was negatively associated with buprenorphine discontinuation in the postpartum period, with HR 0.63 (95% CI 0.38-1.03) (Figure 1). In our cohort, postpartum buprenorphine continuation outcomes were similar across initiation clinical settings. Outpatient initiation was marginally associated with longer postpartum buprenorphine duration, likely due to selection bias. Our observational cohort was small; findings should be interpreted with caution. Nonetheless, results illustrate need for further investigation into how perinatal clinical systems can expand access to life-saving treatments for OUD, such as by providing flexibility in how patients can engage in treatment.View Large Image Figure ViewerDownload Hi-res image Download (PPT)

Continuing Chronic Buprenorphine Perioperatively is Associated With Reduced Postoperative Opioid Use

IntroductionBuprenorphine is a frequently used medication for opioid use disorder and misunderstanding buprenorphine's unique pharmacology has historically complicated perioperative analgesia. The purpose of this study was to evaluate the association of perioperative buprenorphine continuation in patients with substance use disorder on perioperative opioid use. Materials and methodsThis was a single-center retrospective study at a level 1 trauma academic medical center. Adult patients using outpatient buprenorphine for medication for opioid use disorder admitted with an operating room booking were included. Patients were grouped (continuation, withheld) retrospectively based upon the decision to continue or omit buprenorphine therapy while admitted. The primary outcome of the study was any use of full mu-opioid agonists during days 1-7 of admission. Secondary outcomes included length of stay and average pain scores during days 1-7 of admission. Results43.4% of patients in the continuation cohort used no full mu-opioid agonists during days 1-7 compared to 3.1% of patients in the withheld cohort (P < 0.001). No significant difference in median length of stay was noted (4.7 d [2.8-6.6] versus 6.1 d [4.0-8.2], P = 0.36). There was no statistical difference in average pain scores on postoperative days 1 (5.2 versus 6.9, P = 0.82) and 7 (0 versus 0, P = 0.41). ConclusionsPerioperative continuation of buprenorphine is associated with reduced use of alternative full mu-opioid agents while admitted without impacting pain scores.

Assessing the feasibility, usability and acceptability of the MySafeRx platform among individuals in outpatient buprenorphine treatment: Lessons learned from a pilot randomized controlled trial

BackgroundIncreasing buprenorphine/naloxone (B/N) access for opioid use disorder (OUD) is essential yet ensuring adherence and preventing diversion remains challenging. This study examines the feasibility, usability, and acceptability of MySafeRx, a mobile platform integrating motivational coaching, adherence monitoring, and electronic dispensing during office-based B/N treatment. MethodsIn this multi-site randomized controlled trial, MySafeRx provided coaching and supervised self-administration of B/N by mobile recovery coaches (MRCs) via videoconference. Referred adults (ages 18–65) with OUD were randomized to 1) 42-days of adjunctive MySafeRx treatment (n = 13) or 2) a standard care control group (n = 14). ResultsThe randomized sample was 63% female and 100% White. Twelve of 13 MySafeRx participants completed at least one MRC session. The mean system usability score reported by MySafeRx participants was 78.4 (n = 12). Participants indicated they would recommend MySafeRx to a friend (mean= 4.1 of 5), and that the dispenser (4.1 of 5) and videoconferencing (4.2 of 5) were easy to use. The MRC component had the highest acceptability (4.4 of 5). MRCs observed B/N self-administration for an average of 64.3% of the required study days (men: 68.9%; women: 57.9%). On average, men (n = 4) met with MRCs on 32±14 days versus 47±6 days for women (n = 8). Exploratory analyses did not show significant differences between intervention and control groups. ConclusionsDespite the small sample, this study supports usability and acceptability of MySafeRx. Increased adherence monitoring, even with remote coaching had limited appeal, which impacted feasibility due to slow recruitment, especially as community prescribing with relaxed monitoring requirements became more widespread.

Impact of state and trait anxiety severity on retention and phase advancement in an outpatient buprenorphine treatment program.

Comorbid anxiety is common among buprenorphine patients and may lead to poorer outcomes. This study aimed to examine the prevalence and impact of anxiety severity, measured by the State-Trait Anxiety Inventory (STAI) form Y-1 & Y2 scale, on treatment outcomes (retention and phase advancement) among outpatient buprenorphine-treated patients. A retrospective chart review of 94 patients admitted to an outpatient buprenorphine treatment program was conducted. Patients were dichotomized into high and low severity groups based upon an STAI State Anxiety (S-Anxiety) and STAI Trait Anxiety (T-Anxiety) score ≥60 and <60, respectively. Associations of anxiety severity on successful phase advancement and retention during the first 90 days of treatment were assessed. Twenty-one of 94 (22%) participants reported high S-Anxiety and had a significantly greater likelihood of phase advancement (OR = 12.80, 95% CI = [1.19, 136.71]) than those with low S-Anxiety. No significant associations were found between either S-Anxiety or T-Anxiety and treatment retention. Current alcohol use and UDS negative test results for THC or amphetamines were each associated with phase advancement. THC negative UDS test results were associated with 90-day treatment retention. Contrary to prior reports, buprenorphine patients with higher state anxiety severity demonstrated similar retention and more rapid phase advancement than those with lower state anxiety severity. To our knowledge, this is the first study to quantify current anxiety severity using the STAI scale and evaluate its impact on treatment outcomes among buprenorphine-treated patients.

Comparison of PACU length of stay and opioid requirements of patients maintained on buprenorphine or methadone for opioid use disorder.

Literature supporting best practice of perioperative buprenorphine management for opioid use disorder is evolving with more recent studies trending toward maintenance of home dose. To guide treatment protocols at our institution, we evaluated patients taking medication for opioid use disorder (MOUD) undergoing similar surgeries. Patients were maintained on either their outpatient buprenorphine or methadone. Data were collected on 46 patients maintained on buprenorphine MOUD who underwent surgery. A subset of these patients (n = 24) was compared with 24 patients maintained on methadone MOUD, matched on surgical procedure, admission date, age, and sex. This is a retrospective matched control study. An academic, tertiary, Level 1 trauma center. Primary outcomes were post-operative opioid use and post-anesthesia care unit (PACU) length of stay. No significant differences in demographic characteristics, physical status, comorbid psychiatric diagnoses, or illicit substance use history were observed between patient groups. A higher proportion of patients taking methadone was admitted due to infection (41.7 percent vs 16.7 percent, p = 0.031) and underwent nonelective surgery (75.0 percent vs 45.8 percent, p = 0.039). No significant differences were observed between patients taking buprenorphine versus methadone with respect to PACU length of stay, post-operative opioid consumption, time-to-transition to oral opioids, or discharge opioid prescriptions. Patients taking buprenorphine were more likely to receive intravenous lidocaine (25.0 percent vs 0.0 percent, p = 0.031) and ketamine (83.3 percent vs 54.2 percent, p = 0.039). Findings from this study support accumulating evidence that patients should be maintained on buprenorphine MOUD throughout the perioperative period.

Identifying barriers to emergency department-initiated buprenorphine: A spatial analysis of treatment facility access in Michigan.

Emergency department (ED)-initiated buprenorphine/naloxone has been shown to improve treatment retention and reduce illicit opioid use; however, its potential may be limited by a lack of accessible community-based facilities. This study compared one state's geographic distribution of EDs to outpatient treatment facilities that provide buprenorphine treatment and identified ED and geographic factors associated with treatment access. Treatment facility data were obtained from the SAMHSA 2018 National Directory of Drug and Alcohol Abuse Treatment Facilities, and ED data were obtained from the Michigan College of Emergency Physician's 2018 ED directory. Geospatial analysis compared EDs to buprenorphine treatment facilities using 5-, 10-, and 20-mile network buffers. Among 131 non-exclusively pediatric EDs in Michigan, 57 (43.5%) had a buprenorphine treatment facility within 5miles, and 66 (50.4%) had a facility within 10miles. EDs within 10miles of a Medicaid-accepting, outpatient buprenorphine treatment facility had higher average numbers of beds (41 vs. 15; p<0.0001) and annual patient volumes (58,616 vs. 17,484; p<0.0001) compared to those without. Among Michigan counties with EDs, those with at least one buprenorphine facility had larger average populations (286,957 vs. 44,757; p=0.005) and higher annual rates of opioid overdose deaths (mean 18.3 vs. 13.0 per 100,000; p = 0.02) but were similar in terms of opioid-related hospitalizations and socioeconomic distress. Only half of Michigan EDs are within 10miles of a buprenorphine treatment facility. Given these limitations, expanding access to ED-initiated buprenorphine in states similar to Michigan may require developing alternative models of care.

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

Background: People with opioid use disorder (OUD) are increasingly started on buprenorphine in the hospital, yet many patients do not attend outpatient buprenorphine care after discharge. Peer providers, people in recovery themselves, are a growing part of addiction care. We examine whether patients who received a low-intensity, peer-delivered intervention during hospitalization had a greater rate of linking with outpatient buprenorphine care relative to those not seen by a peer. Methods: This was a retrospective cohort study of adults with OUD who were started on buprenorphine during hospitalization. The primary outcome was receipt of a buprenorphine prescription within 30 days of discharge. Secondary outcomes included attendance at a follow-up visit with a buprenorphine provider within 30 days and hospital readmission within 90 days. Modified Poisson regression analyses tested for differences in the rate ratios (RR) of each binary outcome for patients who were versus were not seen by a peer provider. Peer notes in the electronic health record were reviewed to characterize peer activities. Results: 111 patients met the study inclusion criteria, 31.5% of whom saw a peer provider. 55.0% received a buprenorphine prescription within 30 days of hospital discharge. Patients with versus without peer provider encounters did not significantly differ in the rates of receiving a buprenorphine prescription (RR = 1.06, 95% CI: 0.74-1.51), hospital readmission (RR = 1.45, 95% CI: 0.80-2.64), or attendance at a buprenorphine follow-up visit (RR = 1.03, 95% CI: 0.68-1.57). Peers most often listened to or shared experiences with patients (68.6% of encounters) and helped facilitate medical care (60.0% of encounters). Conclusions: There were no differences in multiple measures of buprenorphine follow-up between patients who received this low-intensity peer intervention and those who did not. There is need to investigate what elements of peer provider programs contribute to patient outcomes and what outcomes should be assessed when evaluating peer programs.

Low Dose Buprenorphine Induction With Full Agonist Overlap in Hospitalized Patients With Opioid Use Disorder: A Retrospective Cohort Study.

To describe the outcomes of buprenorphine/naloxone low dose induction with overlap of full opioid agonists among hospitalized patients with opioid use disorder (OUD) as an alternative to standard induction strategies. Retrospective cohort study of patients with OUD who were admitted to the hospital over a 1-year period and initiated ono buprenorphine using initial doses of 0.5 mg and gradually increased while the patient remained on full agonists. Descriptive variables included basic demographics, reason for switching to buprenorphine, baseline opioid and morphine equivalent dose. The primary outcome was a successful transition defined by the patient leaving the hospital with a buprenorphine prescription. Bivariate analysis identified factors associated with unsuccessful medication transitions. Secondary outcomes included reported withdrawal symptoms and 30 day follow up to an outpatient buprenorphine program. Sixty two patients underwent low dose with overlap induction during the study period. Fourteen patients were on methadone for OUD before hospital admission. Fifty one patients (82%) successfully left the hospital with a prescription for buprenorphine. Factors associated with lower likelihood of success included older age, transitioning due to discharge placement needs and presence of withdrawal symptoms during the transition. Overall, 66% (N = 23) of patients referred within the same health care system followed up within 30 days. Low dose inductions with overlap of full opioid agonists were largely successful in transitioning hospitalized patients from full agonist opioids to buprenorphine. However, there were several factors associated with lower likelihood of success. Future work could focus on treatment of withdrawal symptoms and system-level changes ensuring patient-centered medication decisions.

Continuation of outpatient buprenorphine therapy after dispensing Buprenorphine-Naloxone from the emergency department

Background Patients with opioid use disorder (OUD) are frequently seen in the ED for opioid-related reasons, which creates an opportunity for ED providers to discuss medications for OUD with their patients. Buprenorphine is a partial mu-opioid agonist that is FDA approved to treat OUD and may be initiated in the ED. Traditionally, buprenorphine therapy was initiated under healthcare provider observation; however, other strategies such as at-home induction have also emerged. Methods This was a retrospective descriptive analysis of patients aged 18 years or older who received a take-home supply of buprenorphine-naloxone from an urban, academic ED between March 2018 and March 2020. The primary outcome was the proportion of patients who filled a prescription for buprenorphine at three months after index ED visit. The proportion of patients that filled a prescription for buprenorphine at six months was also evaluated. The primary safety endpoint was the proportion of patients with return ED visit within six months related to opioid overdose. Results There were 242 patient records reviewed with 155 patients included in final analysis. Seventy (45.2%) patients filled buprenorphine prescriptions at three months, with 64 (41.3%) who filled buprenorphine prescriptions at six months. Seventeen (11%) patients had a return ED visit related to opioid overdose within six months. Conclusion Dispensing buprenorphine take-home kits from the ED resulted in continuation of outpatient buprenorphine in almost 50% of patients. Further studies are warranted to define the role of ED-dispensed buprenorphine.
