Evaluating buprenorphine prescribing and opioid-related health outcomes following the expansion the buprenorphine waiver program.

ABSTRACT:

Aims

To evaluate associations between new types of buprenorphine waivers (nurse practitioner and physician assistant [NP/PA]; 275-patient limit [MD/DO-275]) and both buprenorphine prescribing and health outcomes.

Methods

Using comprehensive county-level data from California 2010-2018, we modeled quarterly associations between numbers of NP/PA and MD/DO-275 waivers and rates of buprenorphine prescribing, opioid-related deaths, emergency department (ED) visits, and hospitalizations among all counties and separately among metropolitan and nonmetropolitan counties using Poisson regression models with county and quarter fixed effects and adjusting for time-varying covariates.

Results

Each additional NP/PA and MD/DO-275 waiver was associated with a 2.6% (95%CI: 1.1-4.1%) and 5.8% (4.1-7.4%) increase in buprenorphine prescribing among nonmetropolitan counties, respectively. Each additional MD/DO-275 waiver was associated with a 2.8% (1.0%-4.6%) increase in buprenorphine among metropolitan counties. There were no statistically significant associations between NP/PA waivers and buprenorphine prescribing among metropolitan counties or among either waiver type and opioid-related health outcomes.

Conclusions

NP/PA waivers were associated with increased buprenorphine prescribing among nonmetropolitan counties and MD/DO-275 waivers were associated with increased buprenorphine prescribing among both metropolitan and nonmetropolitan counties.

Project description:ImportanceLocal-level data are needed to understand whether the relaxation of X-waiver training requirements for prescribing buprenorphine in April 2021 translated to increased buprenorphine treatment.ObjectiveTo assess whether relaxation of X-waiver training requirements was associated with changes in the number of clinicians waivered to and who prescribe buprenorphine for opioid use disorder and the number of patients receiving treatment.Design, setting, and participantsThis serial cross-sectional study uses an interrupted time series analysis of 2020-2022 data from the HEALing Communities Study (HCS), a cluster-randomized, wait-list-controlled trial. Urban and rural communities in 4 states (Kentucky, Massachusetts, New York, and Ohio) with a high burden of opioid overdoses that had not yet received the HCS intervention were included.ExposureRelaxation of X-waiver training requirements (ie, allowing training-exempt X-waivers) on April 28, 2021.Main outcomes and measuresThe monthly number of X-waivered clinicians, X-waivered buprenorphine prescribers, and patients receiving buprenorphine were each summed across communities within a state. Segmented linear regression models to estimate pre- and post-policy change by state were used.ResultsThe number of individuals in 33 participating HCS communities included 347 863 in Massachusetts, 815 794 in Kentucky, 971 490 in New York, and 1 623 958 in Ohio. The distribution of age (18-35 years: range, 29.4%-32.4%; 35-54 years: range, 29.9%-32.5%; ≥55 years: range, 35.7%-39.3%) and sex (female: range, 51.1%-52.6%) was similar across communities. There was a temporal increase in the number of X-waivered clinicians in the pre-policy change period in all states, which further increased in the post-policy change period in each state except Ohio, ranging from 5.2% (95% CI, 3.1%-7.3%) in Massachusetts communities to 8.4% (95% CI, 6.5%-10.3%) in Kentucky communities. Only communities in Kentucky showed an increase in the number of X-waivered clinicians prescribing buprenorphine associated with the policy change (relative increase, 3.2%; 95% CI, 1.5%-4.9%), while communities in other states showed no change or a decrease. Similarly, only communities in Massachusetts experienced an increase in patients receiving buprenorphine associated with the policy change (relative increase, 1.7%; 95% CI, 0.8%-2.6%), while communities in other states showed no change.Conclusions and relevanceIn this serial cross-sectional study, relaxation of X-waiver training requirements was associated with an increase in the number of X-waivered clinicians but was not consistently associated with an increase in the number of buprenorphine prescribers or patients receiving buprenorphine. These findings suggest that training requirements may not be the primary barrier to expanding buprenorphine treatment.

Project description:ImportanceRetention in buprenorphine therapy is associated with a lower risk of opioid overdose. Nevertheless, many patients discontinue treatment, and there is limited evidence to guide buprenorphine tapering.ObjectiveTo understand what prescribing characteristics are associated with opioid overdose following buprenorphine taper.Design, setting, and participantsThis is a population-based, retrospective, cohort study of adults who were maintained on buprenorphine for at least 60 days and underwent a buprenorphine taper. The study was conducted in the Canadian province of Ontario, using linked administrative health data. New buprenorphine treatment episodes were accrued between January 1, 2013, and January 1, 2019, and the maximum follow-up was April 30, 2020. Data analysis was performed from December 2020 to August 2022.ExposuresThe primary exposure of interest was time to taper initiation (≤1 year vs >1 year). Secondary exposures included mean rate of taper, percentage days during which the dose was decreasing, and taper duration.Main outcomes and measuresThe primary outcome measure was time to fatal or nonfatal opioid overdose within 18 months following treatment discontinuation.ResultsAmong 5774 individuals, the median (IQR) age at index date was 34 (28-44) years, and 3462 individuals (60.0%) were male. Time to taper initiation longer than 1 year vs 1 year or less (6.73 vs 10.35 overdoses per 100 person-years; adjusted hazard ratio [aHR], 0.69; 95% CI, 0.48-0.997), a lower mean rate of taper (≤2 mg per month, 6.95 overdoses per 100 person-years; >2 to ≤4 mg per month, 11.48 overdoses per 100 person-years; >4 mg per month, 17.27 overdoses per 100 person-years; ≤2 mg per month vs >4 mg per month, aHR, 0.65; 95% CI, 0.46-0.91; >2 to ≤4 mg per month vs >4 mg per month, aHR, 0.69; 95% CI, 0.51-0.93), and dose decreases in 1.75% or less of days vs more than 3.50% of days during the taper period (5.87 vs 13.87 overdoses per 100 person-years; aHR, 0.64; 95% CI, 0.43-0.93) were associated with reduced risk of opioid overdose; however, taper duration was not.Conclusions and relevanceIn this retrospective cohort study, buprenorphine tapers undertaken after at least 1 year of therapy, a slower rate of taper, and a lower percentage of days during which the dose was decreasing were associated with a significantly lower risk of opioid overdose, regardless of taper duration. These findings underscore the importance of a carefully planned taper and could contribute to reduction in opioid-related overdose death.

Project description:BackgroundOpioid-involved overdose deaths continue to rise in the US, despite availability of highly effective treatments for opioid use disorder (OUD), in part due to the insufficient number of treatment providers. Barriers include the need for providers to gain expertise and confidence in providing MOUD to their patients who need these treatments. To mitigate this barrier, New Jersey sponsored a buprenorphine training program with financial incentives for participation, which met the then existing requirement for the DATA-2000 waiver. In a 2019 follow-up survey, participants reported on barriers and facilitators to subsequent buprenorphine prescribing.MethodsParticipants in the training program completed a 10-min electronic survey distributed via email. The survey addressed demographics, practice characteristics, current buprenorphine prescribing, and barriers and facilitators to adoption and/or scale up of buprenorphine prescribing.ResultsOf the 440 attendees with a valid email address, 91 individuals completed the survey for a response rate of 20.6%. Of the 91 respondents, 89 were eligible prescribers and included in the final analysis. Respondents were predominantly female (n = 55, 59.6%) and physicians (n = 55, 61.8%); representing a broad range of specialties and practice sites. 65 (73%) of respondents completed the training and DEA-registration, but only 31 (34.8%) were actively prescribing buprenorphine. The most frequently cited barriers to buprenorphine prescribing were lack of access to support services such as specialists in addiction, behavioral health services, and psychiatry. The most frequently reported potential facilitators were integrated systems with direct access to addiction specialists and psychosocial services, easier referral to behavioral health services, more institutional support, and improved guidance on clinical practice standards for OUD treatment.ConclusionMore than half (52.3%) of those who completed incentivized training and DEA registration failed to actively prescribe buprenorphine. Results highlight provider perceptions of inadequate availability of support for the complex needs of patients with OUD and suggest that broader adoption of buprenorphine prescribing will require scaling up support to clinicians, including increased availability of specialized addiction and mental health services.

Project description:BackgroundDespite efforts to improve access to Medications for Opioid Use Disorder (MOUD), such as buprenorphine, the number of opioid overdoses in the United States continues to rise. In April 2021, the Department of Health and Human Services removed the mandatory training requirement to obtain a buprenorphine waiver; the goal was to encourage more providers to prescribe buprenorphine, thus improving access. Little is known about the attitudes on buprenorphine prescribing after this policy change.ObjectiveThe primary objective was to assess attitudes among primary care providers toward the removal of the buprenorphine waiver training requirement. A secondary objective was to identify other barriers to prescribing buprenorphine.MethodsWe conducted a survey between September 15 and October 13, 2021 to assess the overall beliefs on the effectiveness of MOUD and attitudes toward the removal of the waiver training, current knowledge of buprenorphine, current practice styles related to screening for and treating OUD, and attitudes toward prescribing buprenorphine in the future. This survey was sent to 890 Mayo Clinic primary care providers in 5 US states.ResultsOne hundred twenty-three respondents (13.8%) completed the survey; 35.8% respondents agreed that the removal of the waiver training was a positive step. These respondents expressed a greater familiarity with the different formulations, pharmacology, and titration of buprenorphine. This group was also more likely to prescribe (or continue to prescribe) buprenorphine in the future. Approximately one-third (34.4%) of respondents reported perceived institutional support in prescribing buprenorphine. This group expressed greater confidence in diagnosing OUD, had greater familiarity with the different formulations, pharmacology, and titration of buprenorphine, and was more likely to prescribe (or continue to prescribe) buprenorphine in the future. Respondents who have been in practice for 11 to 20 years since completion of training were most likely to refer all OUD patients to specialists.ConclusionsResults of our survey suggests that simply removing the mandatory waiver training requirement is insufficient in positively changing attitudes toward buprenorphine prescribing. A key barrier is the perceived lack of institutional support. Future studies investigating effective ways to provide such support may help improve providers' willingness to prescribe buprenorphine.

Project description:ImportanceThe COVID-19 pandemic disrupted medical care, impacting prescribing of opioid analgesics and buprenorphine for opioid use disorder. Understanding these patterns can help address barriers to care.ObjectiveTo evaluate how prescribing of opioid analgesics and buprenorphine for opioid use disorder changed throughout the COVID-19 pandemic among both new and existing patients.Design, setting, and participantsIn this cross-sectional study, use of opioid analgesics and buprenorphine for opioid use disorder from March 18 to September 1, 2020, was projected using a national database of retail prescriptions from January 1, 2018, to March 3, 2020. Actual prescribing was compared with projected levels for all, existing, and new patients.ExposuresThe data include prescriptions to patients independent of insurance status or type and cover 90% of retail prescriptions, 70% of mail-order prescriptions, and 70% of nursing home prescriptions.Main outcomes and measuresPrescriptions for opioid analgesics and buprenorphine for opioid use disorder. Outcomes included total number of prescriptions, total morphine milligram equivalents, mean morphine milligram equivalents per prescription, mean dispensed units per prescription, and number of patients filling prescriptions.ResultsA total of 452 691 261 prescriptions for opioid analgesics and buprenorphine for opioid use disorder were analyzed for 90 420 353 patients (50 921 535 female patients [56%]; mean [SD] age, 49 [20] years). From March 18 to May 19, 2020, 1877 million total morphine milligram equivalents of opioid analgesics were prescribed weekly vs 1843 million projected, a ratio of 102% (95% prediction interval [PI], 94%-111%; P = .71). The weekly number of opioid-naive patients receiving opioids was 370 051 vs 564 929 projected, or 66% of projected (95% PI, 63%-68%; P < .001). Prescribing of buprenorphine was as projected for existing patients, while the number of new patients receiving buprenorphine weekly was 9865 vs 12 008 projected, or 82% (95% PI, 76%-88%; P < .001). From May 20 to September 1, 2020, opioid prescribing for new patients returned to 100% of projected (95% PI, 96%-104%; P = .95), while the number of new patients receiving buprenorphine weekly was 10 436 vs 11 613 projected, or 90% (95% PI, 83%-97%; P = .009).Conclusions and relevanceIn this cross-sectional study, existing patients receiving opioid analgesics and buprenorphine for opioid use disorder generally maintained access to these medications during the COVID-19 pandemic. Opioid prescriptions for opioid-naive patients decreased briefly and then rebounded, while initiation of buprenorphine remained at a low rate through August 2020. Reductions in treatment entry may be associated with increased overdose deaths.

Project description:ImportanceAs opioid-related deaths continue to climb, methods to reduce barriers to prescribing buprenorphine for individuals with opioid use disorder (OUD) are needed. Recent conversations by state and federal authorities targeting low-threshold buprenorphine aim to reduce some barriers to prescribing buprenorphine; however, what remains unclear is whether removal of the requirement to obtain a waiver for prescribing buprenorphine through the Drug Addiction Treatment Act of 2000 (an X-waiver) will be enough to increase access to buprenorphine.ObjectiveTo assess barriers and facilitators of obtaining an X-waiver and prescribing buprenorphine.Design, setting, and participantsThis mixed-method survey study was conducted between September and December 2020; 607 office-based Texas clinicians were surveyed after they attended a buprenorphine X-waiver training course. All attendees between March 2, 2019, and February 28, 2020, were eligible to receive this survey; 126 responses were received (20% response rate: 81 physicians, 37 nurse practitioners, and 8 physician assistants). Data analysis was performed October 2021.Main outcomes and measuresSurveys measured the extent to which clinicians experienced 9 previously identified barriers during the waiver process and in prescribing buprenorphine. The survey included open-ended items assessing facilitating factors to obtaining a waiver and to prescribing buprenorphine for OUD. The barriers were analyzed using χ2 tests of homogeneity. Qualitative data were analyzed using a constant comparative method.ResultsAmong 126 clinicians who responded, 61 (48.4%) had received an X-waiver; of these waivered clinicians, 22 (36%) were prescribing buprenorphine and 39 (64%) were not. "Complexity of X-waiver process," "Perceived lack of professional support and referral network," and "Getting started" were significantly different barriers among waivered and nonwaivered clinicians. Significant differences in barriers experienced between prescribers and nonprescribers were "Getting started" and "Accessing reimbursement for treatment." The most frequently mentioned facilitators involved changes to the waiver training and the need for networks connecting experienced clinicians with those in the initial stages of readiness for prescribing buprenorphine for OUD.Conclusions and relevanceThis survey study's results contribute new understanding of facilitators to obtaining the X-waiver and to prescribing buprenorphine. Furthermore, these findings suggest that to increase access to compassionate evidence-based treatment for OUD, clinicians need ongoing support and mentorship from experienced and knowledgeable clinicians. Interventions aimed at improving access to buprenorphine should focus on facilitating such networks to increase the number of clinicians who obtain an X-waiver and prescribe buprenorphine for OUD.
