Buprenorphine treatment retention and comorbidities among patients with opioid use disorder in a primary care setting.

BACKGROUND AND OBJECTIVES: More information is needed about comorbidities among patients receiving buprenorphine maintenance treatment and their relationship with retention. METHODS: Retrospective electronic health record data over a 5-year period from primary care patients receiving buprenorphine for the treatment of opioid use disorder were examined (N = 899). The present analysis determined the prevalence of comorbidities and examined associations with treatment retention as defined by cumulative duration of buprenorphine prescription. RESULTS: Tobacco use and comorbidities including hypertension were prevalent but did not predict retention according to survival analyses controlling for demographic characteristics. Retention was poorer among patients testing positive for cocaine (HR = 1.38, 95% CI: 1.09-1.74, p = .007) and patients with hepatitis C virus (HR = 1.17, 95% CI: 1.01-1.37, p = .04). CONCLUSION AND SCIENTIFIC SIGNIFICANCE: This study provides new knowledge of previously unexamined associations between comorbidities (e.g., hypertension) and buprenorphine treatment retention. The robust association between cocaine use and poorer buprenorphine retention serves to resolve prior conflicting data in the literature.

Overcoming medication stigma in peer recovery: A new paradigm.

BACKGROUND: Treatment for opioid use disorder involving opioid-based pharmacotherapies is considered most effective when accompanied by psychosocial interventions. Peer-led support groups are widely available and have been described by many as fundamental to the recovery process. However, some individuals using medications face stigma in these settings, which can be contradictory and counterproductive to their recovery. METHODS: This paper describes the development of the "Ability, Inspiration and Motivation" or "AIM" group, an alternative peer support group that aims to remove medication stigma from peer recovery. Qualitative interviews with staff, peers, and clients of a community-based buprenorphine treatment program were used to establish the core components of the curriculum to support client needs. RESULTS: Staff, peers, and clients of the buprenorphine program indicated a need and desire to establish a peer recovery group that recognizes persons on medication as being in recovery and destigmatizes use of medication to treat opioid addiction. A respectful environment, holistic perspective on health, spirituality, sharing, and celebration were all established as necessary pillars of the AIM group curriculum. CONCLUSIONS: The community-based effort to establish and develop the AIM group demonstrates that combining the strengths of a peer support with evidence-based medication treatment is both possible and desirable. Shifting the culture of peer recovery groups to support the use of medications may have implications for improving treatment retention and should be considered as a potential strategy to reduce the burden of the opioid epidemic.

What patients with addiction disorders need from their primary care physicians: A qualitative study.

BACKGROUND: Although strong relationships between primary care providers (PCPs) and patients with addictive disease are essential for care, these relationships are often strained. Providers frequently have negative attitudes about treating these patients, in part due to the practical and psychosocial challenges that come with addictive disease. Resulting hostility frequently causes avoidance of primary care by patients with potentially increased morbidity. However, gaining knowledge of patient perspectives on these relationships could improve physician attitudes toward patients with addictive disease and relatedly improve care. METHODS: The authors conducted 18 semistructured interviews of patients with current or prior debilitating addictive disease recruited from a primary care practice in East Baltimore. Interview transcripts were analyzed using editing analysis to reveal major themes. RESULTS: Participants elucidated several provider characteristics that were essential for successful relationships. Providers needed to be knowledgeable about addiction, feel responsible for treating these patients, emphasize overall health, and engage patients in their own care. Additionally, participants strongly desired providers who treated them as "people" that they cared about. Interestingly, interviewees also frequently cited patient characteristics that could affect the strength of patient-provider relationships. These included being concerned about their health, feeling deserving of care, and having appropriate psychiatric care for concomitant mental health conditions. Practical obstacles and a disorganized mindset impeded patient-provider relationships. CONCLUSIONS: The interpersonal dynamics of the patient-provider relationship are particularly important for patients with addictive disease, as this relationship may be one of the most stable and rewarding in their lives. Patients felt that greater understanding of the practical and psychosocial challenges of addiction enabled providers to more effectively address their health concerns and to be more caring and less judgmental. It is hoped that this work will contribute to providers' understanding of patients with addictions, thus allowing them to form stronger relationships and ultimately provide better care.

A comparison of characteristics and outcomes of opioid-dependent patients initiating office-based buprenorphine or methadone maintenance treatment.

BACKGROUND: The purpose of this study was to compare demographic factors and 1-year treatment outcomes of patients treated with buprenorphine or methadone. METHODS: The study included 252 subjects who received a prescription for buprenorphine in an academic internal medicine practice and 252 subjects who enrolled in a methadone maintenance program located on the same campus over the same time frame. Data were collected retrospectively. Patients were classified as "opioid-positive" or "opioid-negative" each month for a year based on urine drug testing and provider assessment. Successful treatment was defined as remaining in treatment after 1 year and achieving 6 or more opioid-negative months. RESULTS: Buprenorphine patients were more likely to be male, have health insurance, be employed, abuse prescription opioids, and be human immunodeficiency virus (HIV) infected; they were less likely to abuse benzodiazepines. At 12 months, 140 (55.6%) of buprenorphine patients and 156 (61.9%) of methadone patients remained in treatment (P =.148). Patients on methadone had a higher mean number of opioid-negative months (6.96 vs. 5.43; P <.001) and mean number of months in treatment (9.38 vs. 8.59; P <.001). On multivariable analysis, methadone maintenance was significantly associated with successful treatment (adjusted odds ratio: 2.10; 95% confidence interval: 1.43-3.07). CONCLUSIONS: Office-based buprenorphine and methadone maintenance programs serve very different populations. Both are effective, but patients on methadone had mildly better treatment outcomes.

Trends in Opioid Use Disorder Outpatient Treatment and Telehealth Utilization Before and During the COVID-19 Pandemic.

OBJECTIVE: The authors examined trends in opioid use disorder treatment and in-person and telehealth modalities before and after COVID-19 pandemic onset among patients who had received treatment prepandemic. METHODS: The sample included 13,113 adults with commercial insurance or Medicare Advantage and receiving opioid use disorder treatment between March 2018 and February 2019. Trends in opioid use disorder outpatient treatment, treatment with medications for opioid use disorder (MOUD), and in-person and telehealth modalities were examined 1 year before pandemic onset and 2 years after (March 2019-February 2022). RESULTS: From March 2019 to February 2022, the proportion of patients with opioid use disorder outpatient and MOUD visits declined by 2.8 and 0.3 percentage points, respectively. Prepandemic, 98.6% of outpatient visits were in person; after pandemic onset, at least 34.9% of patients received outpatient care via telehealth. CONCLUSIONS: Disruptions in opioid use disorder outpatient and MOUD treatments were marginal during the pandemic, possibly because of increased telehealth utilization.

Effect of Exposure to Visual Campaigns and Narrative Vignettes on Addiction Stigma Among Health Care Professionals: A Randomized Clinical Trial.

Importance: Stigma toward people with opioid use disorder (OUD) is pervasive in clinical settings, impeding delivery of high-quality care. To date, no study has evaluated the effect of different stigma-reduction messages or messengers among health care professionals. Objective: To evaluate the effect of OUD-related messages delivered by different messengers on stigma and attitudes toward people with OUD among health care professionals. Design, Setting, and Participants: This randomized clinical trial examined the effects of OUD-related messages delivered by a visual campaign alone or in combination with a written narrative vignette from the perspective of 1 of 3 messengers. Health care professionals in the US were recruited from 2 national online survey panels (Ipsos KnowledgePanel and SurveyHealthcareGlobus). A total of 1842 participants completed a web-based survey measuring stigma toward people with OUD from November 13 to 30, 2020. Interventions: Eight groups were exposed to 1 of 2 message frames. One frame (Words Matter) emphasized the harm of stigmatizing language, and the other (Medication Treatment Works) focused on the effectiveness of medications approved by the US Food and Drug Administration for the treatment of OUD. Message frames were communicated through either a visual campaign alone or a visual campaign in combination with a written narrative vignette from the perspective of a simulated patient with OUD, a clinician, or a health care system administrator. Main Outcomes and Measures: Dimensions of stigma toward people with OUD were measured on 5-point Likert scales that included items about desire for social distance from people with OUD, perception of individual blame for OUD, perspective of OUD as a medical condition, and support for increased governmental spending on OUD treatment. The level of warmth felt toward people with OUD was measured by a feeling thermometer (range, 0-100 points). Results: Among 1842 participants, the mean (SD) age was 47 (13) years; 1324 participants (71.9%) were female, 145 (7.9%) were Hispanic, 140 (7.6%) were non-Hispanic Black, 1344 (73.0%) were non-Hispanic White, and 213 (11.6%) were of other non-Hispanic race (ie, individuals who did not self-report race as Black or White and did not self-report ethnicity as Hispanic). Compared with nonexposure, exposure to the combination of visual campaign and narrative vignette communicating the importance of nonstigmatizing language from the perspective of a patient with OUD was associated with a lower probability (difference, -16.8 percentage points, 95% CI, -26.1 to -7.4; P < .001) of unwillingness to have a person with OUD marry into the family (a measure of social distance preference) and a 7.2-point (95% CI, 3.2-11.1; P < .001) higher warmth rating. Participants exposed to the combined visual campaign and patient vignette about the value of medication treatment for OUD also had significantly lower levels of stigma compared with those in the nonexposed control group (eg, unwillingness to have a person with OUD as a neighbor: difference, -15.3 percentage points; 95% CI, -24.6 to -6.0; P = .001). Conclusions and Relevance: In this study, messages about nonstigmatizing language and effective medication for OUD reduced stigma among health care professionals. Stigma-reduction efforts targeting health care professionals may improve health care system capacity to serve people with OUD. Trial Registration: ClinicalTrials.gov Identifier: NCT05127707.

Studying how state health services delivery policies can mitigate the effects of disasters on drug addiction treatment and overdose: Protocol for a mixed-methods study.

BACKGROUND: The United States is experiencing a drug addiction and overdose crisis, made worse by the COVID-19 pandemic. Relative to other types of health services, addiction treatment and overdose prevention services are particularly vulnerable to disaster-related disruptions for multiple reasons including fragmentation from the general medical system and stigma, which may lead decisionmakers and providers to de-prioritize these services during disasters. In response to the COVID-19 pandemic, U.S. states implemented multiple policies designed to mitigate disruptions to addiction treatment and overdose prevention services, for example policies expanding access to addiction treatment delivered via telehealth and policies designed to support continuity of naloxone distribution programs. There is limited evidence on the effects of these policies on addiction treatment and overdose. This evidence is needed to inform state policy design in future disasters, as well as to inform decisions regarding whether to sustain these policies post-pandemic. METHODS: The overall study uses a concurrent-embedded design. Aims 1-2 use difference-in-differences analyses of large-scale observational databases to examine how state policies designed to mitigate the effects of the COVID-19 pandemic on health services delivery influenced addiction treatment delivery and overdose during the pandemic. Aim 3 uses a qualitative embedded multiple case study approach, in which we characterize local implementation of the state policies of interest; most public health disaster policies are enacted at the state level but implemented at the local level by healthcare systems and local public health authorities. DISCUSSION: Triangulation of results across methods will yield robust understanding of whether and how state disaster-response policies influenced drug addiction treatment and overdose during the COVID-19 pandemic. Results will inform policy enactment and implementation in future public health disasters. Results will also inform decisions about whether to sustain COVID-19 pandemic-related changes to policies governing delivery addiction and overdose prevention services long-term.

Integration of Buprenorphine Treatment with Primary Care: Comparative Effectiveness on Retention, Utilization, and Cost.

Opioid use disorder (OUD) is a national crisis. Health care must achieve greater success than it has to date in helping opioid users achieve recovery. Integration of comprehensive primary care with treatment for OUD has the potential to increase care access among the substance-using population, improve outcomes, and reduce costs. However, little is known about the effectiveness of such care models. The Comprehensive Care Practice (CCP), a primary care practice located in Maryland, implemented a care model that blends buprenorphine treatment for OUD with attention to primary care needs. This study evaluates the model by comparing patients with OUD treated in CCP and other Maryland facilities in a large state Medicaid program. Compared to the non-CCP patient group (n = 867), the CCP group (n = 131) had a higher 6-month buprenorphine treatment retention rate (79% vs. 61%, adjusted average marginal effect (AME) = 0.17, P < 0.001). CCP patients also had fewer hospital stays in the 12-month follow-up period (0.22 vs. 0.41, AME = -0.17, P = 0.005), and lower total cost (US$10,942 vs. $13,097, AME = -$4554, P < 0.001) and hospital stay cost (US$1448 vs. $4265, AME = -$2609, P = 0.001), but higher buprenorphine pharmacy cost (US$3867 vs. $2781, AME = $987, P < 0.001). Other measures, including emergency department utilization and cost, substance abuse cost, and non-buprenorphine pharmacy cost, were not statistically different between the 2 groups. Results suggested that patients, as well as the health care system, can benefit from an integrated model of buprenorphine treatment and primary care for OUD with better treatment retention, fewer hospital stays, and lower costs.

Expanding low-threshold buprenorphine to justice-involved individuals through mobile treatment: Addressing a critical care gap.

BACKGROUND: Opioid use disorder (OUD) is highly prevalent among justice-involved individuals. While risk for overdose and other adverse consequences of opioid use are heightened among this population, most justice-involved individuals and other high-risk groups experience multiple barriers to engagement in opioid agonist treatment. METHODS: This paper describes the development of Project Connections at Re-Entry (PCARE), a low-threshold buprenorphine treatment program that engages vulnerable patients in care through a mobile van parked directly outside the Baltimore City Jail. Patients are referred by jail staff or can walk in from the street. The clinical team includes an experienced primary care physician who prescribes buprenorphine, a nurse, and a peer recovery coach. The team initiates treatment for those with OUD and refers those with other needs to appropriate providers. Once stabilized, patients are transitioned to longer-term treatment programs or primary care for buprenorphine maintenance. This paper describes the process of developing this program, patient characteristics and initial outcomes for the first year of the program, and implications for public health practice. RESULTS: From November 15, 2017 through November 30, 2018, 220 people inquired about treatment services and completed an intake interview, and 190 began treatment with a buprenorphine/naloxone prescription. Those who initiated buprenorphine were primarily male (80.1%), African American (85.1%), had a mean age of 44.1 (SD = 12.2), and a mean of 24.0 (SD = 13.6) years of opioid use. The majority of patients (94.4%) had previous criminal justice involvement, were unemployed (72.9%) and were unstably housed (70.8%). Over a third (32.1%) of patients had previously overdosed. Of those who began treatment, 67.9% returned for a second visit or more, and 31.6% percent were still involved in treatment after 30 days. Of those who initiated care, 20.5% have been transferred to continue buprenorphine treatment at a partnering site. CONCLUSIONS: The PCARE program illustrates the potential for low-threshold buprenorphine treatment to engage populations who are justice-involved and largely disconnected from care. While more work is needed to improve treatment retention among vulnerable patients and engaging persons in care directly after release from detention, offering on-demand, flexible and de-stigmatizing treatment may serve as a first point to connect high-risk populations with the healthcare system and interventions that reduce risk for overdose and related harms.

Racial and ethnic differences in opioid agonist treatment for opioid use disorder in a U.S. national sample.

BACKGROUND: Opioid Agonist Treatment (OAT) is the standard of care for the treatment of opioid use disorders. However, most people in treatment do not receive OAT. This study evaluated whether there are racial and/or ethnic differences in OAT receipt among adults entering specialty treatment for opioid use disorders in publicly-funded treatment programs across the U.S. METHODS: Using data from the national Treatment: Episode Data Base, odds of OAT receipt were compared among black, Hispanic and white clients. Mediation analyses were used to explore whether any racial/ethnic differences in OAT receipt were explained by variation in clinical need or by other treatment, sociodemographic, or geographic characteristics. Interaction terms were used to assess whether this association was modified by primary opioid type. RESULTS: Only 28.7% of clients received OAT. Odds of OAT receipt were significantly higher odds among blacks (OR: 2.27(2.14-2.41)) and Hispanics (OR: 1.98(1.88-2.09)), compared to whites. Differences in clinical need accounted for a substantial portion of this difference (76.79% and 49.74%, respectively). Differences persisted after accounting for other potential explanatory variables (adjusted OR: 1.37 (1.24-1.52); 1.21(1.11-1.32)), but were only evident for primary heroin users (adjusted OR: 1.50 (1.34-1.69); 1.29 (1.17-1.42)) and not other opioid users. CONCLUSIONS: OAT receipt in treatment programs is low overall and particularly lacking among white heroin users. Differences in OAT receipt cannot be fully explained by differences in clinical need. More research is needed to understand and address barriers that underpin these differences so more patients with opioid use disorder can access evidenced-based treatment.

Impact of hepatitis C status on 20-year mortality of patients with substance use disorders.

BACKGROUND: The magnitude of the effect of hepatitis C viral infection on survival is still not fully understood. The objective of this study was to determine whether the presence of hepatitis C viral antibodies in 1991 was associated with increased mortality 20 years later within a cohort of patients with substance use disorders. Secondary objectives were to determine other factors that were associated with increased mortality in the cohort. METHODS: A subset of a 1991 study cohort of patients who had presented for detoxification was reexamined 20 years later. The Social Security Death Index was queried to identify which of the original patients had died. Attributes of survivors and non-survivors were compared, with special attention to their hepatitis C status in 1991. The original study and this analysis were conducted in the chemical detoxification unit at Johns Hopkins Bayview (previously Francis Scott Key Hospital), an academic urban hospital. All participants met the criteria for alcohol or opioid dependence at the time of admission in 1991. The primary study outcome was 20-year mortality after initial admission in 1991, with a planned analysis of hepatitis C status. RESULTS: Twenty years after admission, 362 patients survived and 82 had died. Of the 284 patients who were hepatitis C positive, 228 survived (80 %). Of the 160 patients who were hepatitis C negative, 134 survived (84 %). This absolute risk increase of 4 % was not statistically significant (p = 0.37). Factors associated with increased mortality included male sex, white race, older age, and reported use of alcohol, cocaine, and illicit methadone. Binary logistic regression including hepatitis C status and these other variables yielded an adjusted odds ratio of 0.87 (95 % CI 0.49-1.55); (p = 0.64) for hepatitis C positive 20-year survival. CONCLUSIONS: Hepatitis C positivity was not associated with a statistically significant difference in 20-year survival. The effect of the virus on mortality, if present, is small, relative to the effect of substance use disorders alone.

A Comparison of Clonidine and Buprenorphine in the Outpatient Treatment of Opiate Withdrawal.

The opiate withdrawal syndrome, although not life threatening, is a major obstacle in the treatment of opiate dependence. Over a 12 week period, 124 patients (63% female, 66% African American and mean age 32.6 years) underwent 5 day treatment for opiate withdrawal. Patients treated in the first 6 weeks (n = 69) received clonidine based treatment (0.1 mg every 6 h with one dose received on-site each day and the others taken home), while patients treated in the latter 6 weeks (n = 65) received buprenorphine 0.3 mg IM daily. Both groups received supportive medications for diarrhea, cramps, aches, and nausea, had clonidine patches placed on day 4, and were offered naltrexone upon completion. Based on age, gender, and race the two treatment groups were similar. The completion rate was 75.4% for buprenorphine group and 47.5% for the clonidine group, (p =.001). In conclusion, buprenorphine was superior to clonidine in enabling opiate dependent patients to successfully complete an outpatient detoxification program.

A novel community-based buprenorphine program: client description and initial outcomes.

The aims of this retrospective, descriptive study were to describe clients served by a buprenorphine program in a community-based recovery center and to present initial treatment outcomes. A record review was conducted for clients treated from July 2010 to August 2011. Client demographic, health, substance use, and treatment history data were abstracted from the records of the first 78 clients served. Buprenorphine and opiate use data were collected via urine toxicology reports, collected weekly among clients who remained enrolled in treatment. The average percentages of weeks spent opiate free and buprenorphine compliant were 83% (SD = 26%) and 95% (SD = 13%), respectively. When positive heroin toxicology and negative buprenorphine toxicology were replaced for the missing/unknown data, the average percentages of opiate-abstinent weeks and buprenorphine compliance were 60% (SD = 34%) and 74% (SD = 28%), respectively. Roughly half of all clients (49%) were successfully transitioned to continue treatment with buprenorphine in a primary care setting. Findings from this study demonstrate that buprenorphine treatment for opiate dependence can be incorporated into a community-based recovery center with high rates of opiate abstinence and treatment adherence.

Buprenorphine maintenance treatment in a primary care setting: outcomes at 1 year.

The purposes of this study were to assess outcomes of patients prescribed buprenorphine at a primary care practice and to identify factors associated with favorable outcomes. All 255 patients given at least one prescription for buprenorphine between August 2003 and September 1, 2007, at a primary care practice in Baltimore were included. Data regarding demographics and comorbidities were collected retrospectively. Patients were classified as "opioid-positive" or "opioid-negative" each month based on patient report, urine toxicology, and provider assessment. After 12 months, 145 (56.9%) patients remained in treatment, and 64.7% of their months were opioid-negative. Patients using heroin were less likely to be opioid-negative, whereas those using prescription opioids were more likely to be opioid-negative. Polysubstance use was associated with increased treatment retention. The prescription of buprenorphine for opioid dependence treatment can be incorporated into primary care practice, and many patients, including polysubstance users, benefit from this treatment.

A resident clerkship that combines inpatient and outpatient training in substance abuse and HIV care.

Substance abuse and HIV infection are important medical problems that receive comparatively little attention in residency training programs and residents often feel unprepared to deal with them. We developed a month-long rotation that combined outpatient care for patients with HIV infection and addiction, with inpatient care for medically-ill patients on a detoxification unit. At the end of the rotation, residents reported greater comfort with caring for these patients and improved self-rated competence. They also rated the rotation highly. Our experience shows that a rotation combining inpatient and outpatient substance abuse and HIV care was valued by residents and increased their comfort and proficiency with caring for these underserved and stigmatized populations.
