Association of primary care engagement with initiation and continuation of medication treatment for opioid use disorder among persons with a history of injection drug use

Leveraging Telehealth in the United States to Increase Access to Opioid Use Disorder Treatment in Pregnancy and Postpartum During the COVID-19 Pandemic.

Critical access medication for opioid use disorder (MOUD) treatment facilities in the continental United States

BackgroundMedication for opioid use disorder (MOUD) is the gold standard treatment for opioid use disorder. Traditionally, “success” in MOUD treatment is measured in terms of program retention, adherence to MOUD, and abstinence from opioid and other drug use. While clinically meaningful, these metrics may overlook other aspects of the lives of people with opioid use disorder (OUD) and surprisingly do not reflect the diagnostic criteria for OUD.MethodsAuthors identified items for a pilesorting task to identify participant-driven measures of MOUD treatment success through semi-structured interviews. Interviews were transcribed verbatim and coded in Nvivo using directed and conventional content analysis to identify measures related to treatment success and quality of life goals. Participants of a low-threshold MOUD program were recruited and asked to rank identified measures in order of importance to their own lives. Multidimensional scaling (MDS) compared the similarity of items while non-metric MDS in R specified a two-dimensional solution. Descriptive statistics of participant demographics were generated in SPSS.ResultsSixteen semi-structured interviews were conducted between June and August 2020 in Philadelphia, PA, USA, and 23 measures were identified for a pilesorting activity. These were combined with 6 traditional measures for a total list of 29 items. Data from 28 people were included in pilesorting analysis. Participants identified a combination of traditional and stakeholder-defined recovery goals as highly important, however, we identified discrepancies between the most frequent and highest ranked items within the importance categories. Measures of success for participants in MOUD programs were complex, multi-dimensional, and varied by the individual. However, some key domains such as emotional well-being, decreased drug use, and attendance to basic functioning may have universal importance. The following clusters of importance were identified: emotional well-being, decreased drug use, and human functioning.ConclusionsOutcomes from this research have practical applications for those working to provide services in MOUD programs. Programs can use aspects of these domains to both provide patient-centered care and to evaluate success. Specifics from the pilesorting results may also inform approaches to collaborative goal setting during treatment.

Trajectories of drug treatment and illicit opioid use in the AIDS Linked to the IntraVenous Experience cohort, 2014-2019.

Background: In Colombia, the rapid rise of illicit opioid use has become a major public health concern. Medications for opioid use disorder (MOUD) are well established and effective. However, access to MOUD remains suboptimal in this country. This paper aims to understand barriers to accessing MOUD in Colombia to inform the integration of this treatment modality in health systems. Methods: This study is a cross-sectional survey among persons with opioid use disorder (OUD) not enrolled in MMT in four Colombian cities with high known OUD prevalence. Survey domains consisted of the Barriers to Treatment Inventory, attitudes pertaining to MOUD treatments, and perceptions regarding interventions to ease access to Methadone. Results: A total of 84 subjects completed the survey. The most commonly endorsed barriers were related to admission difficulties, including concerns with “too many steps to get into treatment” (84.3%), experiencing withdrawal symptoms (78.1%), being placed on waiting lists (48.2%), and cost (44.6%). Nearly all participants were receptive to Methadone dispensation in primary care (96.4%) or mobile vans (91.6%). Conclusions: Findings from this study highlight persistent barriers to linking with MOUD among adults with OUD in Colombia requiring increased outpatient treatment programs, flexible methadone dosing, and administrative and financial support for patients.

Stigma is described as highly relevant to the treatment context for opioid use disorder (OUD) partly because it is known to influence providers' treatment decisions and care provision. However, further study is needed to directly test the salience of stigmatizing views for healthcare decision-making among providers, and particularly those including medication for opioid use disorder (MOUD). This study assessed whether stigma toward illicit opioid use was associated with a willingness to provide or refer patients for MOUD treatment among a sample of healthcare providers. It also evaluated variation in stigmatizing views as a function of familiarity with OUD and MOUD and provider type. Structural equation modeling was utilized to evaluate the antecedents and healthcare decision-making consequences associated with stigma based on survey data from a sample of 144 clinicians participating in a buprenorphine waiver training program (30% female). Providers who have less familiarity with OUD and MOUD and those who are medical students or residents are significantly more likely to endorse stigmatizing views of illicit opioid use. In turn, greater stigma is significantly associated with a lesser willingness to provide treatment or refer patients to MOUD treatment. Further consideration of stigma is recommended in future research to improve clinical practice and increase the implementation of MOUD treatment.

Background: People who inject drugs (PWID) are especially vulnerable to harms from opioid use disorder (OUD). Medications for OUD (MOUD) effectively reduce overdose and infectious disease transmission risks. Objective: We investigate whether state Medicaid coverage for methadone and buprenorphine is related to past-year MOUD use among PWID using cross-sectional, multilevel analyses with individual-level data on PWID from the Centers for Disease Control and Prevention’s 2018 National HIV Behavioral Surveillance. The sample included 8,142 PWID aged 18-64 who reported daily opioid use from 22 U.S. metropolitan areas. Our outcome was any self-reported MOUD use in the past 12 months. Exposures were state Medicaid coverage and prior authorization requirements for methadone and buprenorphine. We interacted these exposures with PWID race/ethnicity, insurance status, and spatial access to treatment and harm reduction resources. Results: Compared with PWID in states without Medicaid methadone coverage, odds of past-year MOUD use were 73% (p<0.05) higher among PWID in states with methadone coverage requiring prior authorization and 80% (p<0.05) higher among PWID in states with coverage without prior authorization. Insured PWID were twice as likely to report MOUD use than uninsured PWID, with no statistically significant differences between Medicaid versus other insurance. Medicaid prior authorization requirements for buprenorphine were not significantly associated with MOUD use. Non-Hispanic Black PWID were significantly less likely to use MOUD than non-Hispanic White and Hispanic PWID. Conclusions: State Medicaid methadone coverage was strongly associated with higher odds that PWID utilized MOUD, suggesting that expanding methadone insurance coverage could improve MOUD treatment in a vulnerable population.

Negative affect-associated drug refusal self-efficacy, illicit opioid use, and medication use following short-term inpatient opioid withdrawal management

Nearly 727 000 individuals in the US died of opioid overdoses between 1999 and 2022. The current workforce of addiction medicine specialists is inadequate to address the scale of this crisis, and primary care clinicians (PCCs) do not feel sufficiently supported to treat opioid use disorder (OUD). To evaluate whether an electronic health record-integrated clinical decision support system (CDSS) increases OUD diagnosis and treatment in primary care. This pragmatic cluster randomized clinical trial was conducted from April 2021 to December 2023. Primary care clinics in 3 health systems in 4 US states were randomized to receive or not receive an electronic health record-integrated CDSS aimed at improving OUD diagnosis and treatment. Eligible patients were aged 18 to 75 years, visited a randomized clinic, and had an OUD diagnosis in the last 2 years, opioid overdose in the last 6 months, or risk score indicating high risk of OUD or opioid overdose. Data were analyzed from September 2023 to October 2024. The OUD CDSS provided personalized treatment recommendations to patients and PCCs in intervention clinics. Primary outcomes were likelihood to receive (1) an OUD diagnosis (among high-risk patients without a baseline OUD diagnosis), (2) a naloxone prescription, or (3) a prescription of a medication for OUD (MOUD) or specialty referral, all within 30 days of first eligible (index) visit, and (4) days covered by a MOUD prescription in the 90 days after index. Among 10 891 patients meeting eligibility criteria, 5918 (54.3%) were female, and the mean (SD) age was 48.0 (13.9) years. There was no difference in OUD diagnoses within 30 days between groups. Patients in the intervention group had more naloxone orders (80 of 5538 [1.4%] vs 40 of 5353 [0.7%]; odds ratio, 1.76; 95% CI, 1.14-2.72) and orders for MOUDs or treatment referral (775 of 5538 [14.0%] vs 503 of 5353 [9.4%]; odds ratio, 1.48; 95% CI, 1.05-2.08) within 30 days. There were no differences in median (IQR) days covered by MOUD over 90 days postindex between intervention (84 [55-90] days) and usual care (83 [55-90] days; rate ratio, 1.00; 95% CI, 0.93-1.08) or in overdose or death rates during the intervention period. In this cluster randomized clinical trial, the intervention improved rates of naloxone orders and OUD treatment in primary care but did not affect days covered by a MOUD over 90 days postindex or overdose or death rates. These findings demonstrate an OUD CDSS can help increase access to OUD treatment in primary care. ClinicalTrials.gov Identifier: NCT04198428.

The criterion-standard treatment for opioid use disorder (OUD) is medications for OUD (MOUD). However, less than a quarter of people with OUD receive MOUD. The collaborative care model (CCM) is an evidence-based practice that integrates mental and physical health treatment in primary care settings. Expanding CCM to include patients with OUD could improve MOUD initiation. To compare the effectiveness of CCM for OUD and co-occurring mental health symptoms (intervention) with CCM for mental health symptoms only (active control). This hybrid type 2a trial cluster-randomized 24 US primary care clinics to intervention or control. Participants included patients with OUD and mental health symptoms who were not receiving specialty mental health care or specialty substance use treatment. Study data were analyzed from February 2024 to January 2025. The control care team included primary care practitioners, care managers, and psychiatric consultants. Primary care practitioners prescribed psychotropic medications with psychiatric consultation. Care manager activities included patient education, engagement and self-management, shared decision-making, measurement-based care for mental health symptoms, and brief psychotherapy for mental health. The intervention had the same components as the control, with additional MOUD training and psychiatric consultation for primary care practitioners, measurement-based care for OUD, and brief psychotherapy for OUD. Participants completed research assessments at baseline, 3 months, and 6 months. The multiple primary outcomes were past-month number of days of using opioids and the Veterans RAND 12 Mental Health Component Summary score. A total of 254 patients (mean [SD] age, 40.9 [12.4] years; 139 women [59.9%]) participated in the trial. Most participants (172 of 212 [81.1%]) were taking MOUD at baseline. Days using opioids decreased in both the control and intervention groups. The intervention significantly reduced opioid use more than the control with a medium effect size (adjusted ratio of odds ratio, 0.10; 95% CI, 0.03-0.38; Cohen d = -0.44; P < .001). Mental Health Component Summary scores improved slightly in both the control and intervention groups. The intervention did not significantly improve scores more than control (adjusted difference in change, -1.20; 95% CI, -4.97 to 2.57; Cohen d = -0.09; P = .53). Findings of this cluster randomized clinical trial indicate that OUD can be successfully managed in primary care with CCM, especially CCM for OUD and mental health symptoms. Primary care clinics with MOUD prescribers should consider implementing CCM for OUD and mental health. ClinicalTrials.gov Identifier: NCT04600414.

Thousands of pregnant people with opioid use disorder (OUD) enter US jails annually, yet their access to medications for OUD (MOUD) that meet the standard of care (methadone and/or buprenorphine) is unknown. To assess the availability of MOUD for the treatment of pregnant individuals with OUD in US jails. In this cross-sectional study, electronic and paper surveys were sent to all 2885 identifiable US jails verified in the National Jails Compendium between August 19 and November 7, 2019. Respondents were medical and custody leaders within the jails. The primary outcome was the availability of MOUD (methadone and/or buprenorphine) for the treatment of pregnant people with OUD in US jails. Availability of MOUD was assessed based on (1) continuation of MOUD for pregnant incarcerated individuals (if the individual was receiving MOUD before incarceration), with or without initiation of MOUD; (2) both initiation and continuation of MOUD for pregnant individuals; (3) only continuation of MOUD for pregnant individuals; and (4) management of opioid withdrawal for pregnant individuals. Secondary outcomes included MOUD availability during the postpartum period and logistical factors associated with the provision of MOUD. Multivariate logistic regression analysis was used to assess factors associated with MOUD availability during pregnancy. Among 2885 total surveys sent, 1139 (39.5%) were returned; of those, 836 surveys (73.4%; 29.0% of all surveys sent) could be analyzed, with similar proportions from metropolitan (399 jails [47.7%]) and rural (381 jails [45.6%]) settings. Overall, 504 jails (60.3%) reported that MOUD was available for medication continuation, with or without medication initiation, during pregnancy. Of those, 267 jails (53.0%; 31.9% of surveys included in the analysis) both initiated and continued MOUD, and 237 jails (47.0%; 28.3% of surveys included in the analysis) only continued MOUD; 190 of 577 jails (32.9%; 22.7% of surveys included in the analysis) reported opioid withdrawal as the only management for pregnant people with OUD. Among the 504 medication-providing jails, only 120 (23.8%) continued to provide MOUD during the postpartum period. Methadone was more commonly available at jails that only continued MOUD (84 of 123 jails [68.3%]), whereas buprenorphine was more commonly available at jails that both initiated and continued MOUD (73 of 119 jails [61.3%]). In an adjusted model, jails with higher odds of MOUD availability were located in the Northeast (odds ratio [OR], 10.72; 95% CI, 2.43-47.36) or metropolitan areas (OR, 1.92; 95% CI, 1.31-2.83), had private health care contracts (OR, 1.49; 95% CI, 1.03-2.14) and a higher number of women (≥70) reported in the female census (OR, 1.69; 95% CI, 1.02-2.80), and provided pregnancy testing within 2 weeks of arrival at the jail (OR, 2.66; 95% CI, 1.69-4.17). In this cross-sectional study, a substantial proportion of US jails did not provide access to MOUD to pregnant people with OUD. Although most jails reported continuing to provide MOUD to individuals who were receiving medication before incarceration, few jails initiated MOUD, and most medication-providing jails discontinued MOUD during the postpartum period. These results suggest that many pregnant and postpartum people with OUD in US jails do not receive medication that is the standard of care and are required to endure opioid withdrawal, signaling an opportunity for intervention to improve care for pregnant people who are incarcerated.

Despite substantial investment in expanding access to treatment for opioid use disorder (OUD), overdose deaths continue to increase. Primary care holds enormous potential to expand access to OUD treatment, but few patients receive medications for OUD (MOUD) in primary care. Understanding both patient and clinician experiences is critical to expanding access to patient-centered MOUD care, yet relatively little research has examined patient perspectives on primary care-based MOUD. We sought to examine the care experiences of patients with OUD receiving medication-based treatment in a primary care setting. We conducted semistructured interviews with patients receiving MOUD at a single primary care site at the University of Utah. Interviews were performed and transcribed by qualitative researchers, who used rapid qualitative analysis using a grounded theory-based approach to identify key themes pertaining to patient experiences receiving medication-based OUD treatment in primary care. Twenty-one patients were screened, and 14 completed the interview. In general, participants had numerous medical and psychiatric comorbidities. The following key themes pertaining to primary care-based OUD treatment were identified: (1) overall health improvement, (2) team-based care, (3) comparing primary care to specialty addiction treatment, (4) access to medications for OUD, and (5) discrimination and stigma. Patients reported many advantages to receiving primary care-based MOUD treatment. In particular, the flexibility and added support of team-based care along with the convenience of receiving addiction treatment alongside regular medical care were highly valued. These findings can be used to develop patient-centered initiatives aimed at expanding OUD treatment within primary care.

Effective adjunctive therapeutic treatments for patients with opioid use disorder (OUD) on medication for OUD (MOUD) in primary care settings are needed to address high rates of mental illness and stress. Behavioral activation (BA) is a brief, evidence-based therapy that has potential to improve quality of life in people with OUD. The purpose of this pilot study was to evaluate the feasibility and acceptability of values-based BA (VBA) as an adjunct treatment for patients receiving MOUD in primary care. Participants were recruited for a single-arm pilot trial of BA in a primary care setting. VBA was adapted for people with OUD and included 4-6 sessions delivered over 12 weeks with a behavioral health consultant, either in-person or virtually. Feasibility was assessed as recruitment percent and pace and retention percent. Acceptability was assessed with the Client Satisfaction Questionnaire-8 (CSQ-8). Participants completed self-report measures of well-being, depression, substance use, and psychological processes of change at baseline, mid-intervention (6-weeks), and post-intervention (12-weeks). Participants engaged in a brief interview about their experiences at the end of the intervention. Twenty-one participants enrolled in the intervention (66.7% female, M age = 44.0 years, 19% of those invited). Participants completed an average of 5.1 BA sessions (SD = 1.6) and most (90%) were retained through 12 weeks. Participants rated the intervention as highly acceptable on the CSQ-8 (M = 30.4/32.0, SD = 1.6). In qualitative interviews, participants reported that working with the therapist and setting values-based goals were helpful, while also recommending more tailoring to patients' needs and offering the program early in MOUD treatment. Preliminary efficacy data suggest the program was associated with small to moderate improvements in life satisfaction (Cohen's d = 0.25) and positive affect (d = 0.62), whereas there were no changes in depression (d = 0.09) or negative affect (d = -0.07) in a group with low depression at baseline. VBA adapted for patients on MOUD in primary care was feasible to deliver and acceptable to participants. Minor modifications to the target population and treatment manual could increase the program's impact. Future studies will test the efficacy of the intervention in improving quality of life and OUD treatment outcomes. https://clinicaltrials.gov/study/NCT05262725, Unique ID: NCT05262725.

Non-prescribing clinicians' treatment orientations and attitudes toward treatments for opioid use disorder: Rural differences

Background: Medication for Opioid Use Disorder (MOUD) is a best practice for treating individuals with opioid use disorder (OUD), and primary care-based MOUD management can reduce treatment barriers among OUD patients. Individuals with OUD experience disproportionately high rates of trauma and violence, highlighting the importance of addressing trauma, mental health, and substance use concurrently. However, clear guidelines for trauma-informed treatment in a primary care setting remain poorly established. Methods: A qualitative approach was engaged to explore primary care providers’ perceptions of barriers and facilitators to assessing and treating trauma among MOUD patients. Twenty in-depth interviews were conducted in 2021 with Baltimore-based MOUD prescribers, including primary care physicians and nurse practitioners. Interview questions assessed experiences with identifying and treating trauma among MOUD patients, including challenges and opportunities. Results: Providers reported extensive histories of trauma experienced by MOUD patients. Barriers to addressing trauma include a lack of standardized protocols/procedures for identifying trauma, insufficient training/time to assess and treat trauma, and the limited availability of external mental health providers and specialty services. Opportunities included building strong, mutually respectful patient-provider relationships, providing individualized, person-centered care, and establishing connections to coordinated multidisciplinary treatment networks. Conclusions: MOUD treatment within primary care is an important way to increase OUD treatment access, but clearer standards are needed for the treatment of trauma within this patient population. These findings demonstrate opportunities to improve standards and systems such that primary care providers are better equipped to assess and treat the complex histories of trauma experienced by individuals with OUD.
