Buprenorphine Dispensing in Pennsylvania During the COVID-19 Pandemic, January to October 2020

Access to Medications for Opioid Use Disorder During COVID-19: Retrospective Study of Commercially Insured Patients from 2019-2022

INTRODUCTION

This study assesses disparities in medications for opioid use disorder in adults with opioid use disorder and examines the associations between state-level COVID-19 lockdown and telehealth policies and medications for opioid use disorder utilization rates during the COVID-19 pandemic.

METHODS

This retrospective cohort study of 396,872 adults with opioid use disorder analyzed monthly medications for opioid use disorder utilization rates between January 2019 and June 2022 using data from Clinformatics Data Mart Database. Primary outcome measure was monthly medications for opioid use disorder utilization rates. Variables of interest were patients' demographics and state-level characteristics (telehealth policies for controlled substance prescribing, COVID-19 lockdown policy, and registered buprenorphine providers/100,000). In multivariable analyses, time trend was grouped into four time periods: before COVID-19, early COVID-19, early vaccine, and Omicron-related COVID-19 surge and thereafter.

RESULTS

Medications for opioid use disorder rates increased from a 1.2% change in slope monthly on a log scale to 2% monthly from February 2021 to October 2021, after which the utilization rate increased to a lesser degree. Women had 28% lower odds of receiving medications for opioid use disorder than men; Hispanic, Black, and Asian patients had 40%, 34%, and 32% lower odds of receiving medications for opioid use disorder than White patients, respectively. These sex and racial disparities persisted throughout the pandemic. Regional medications for opioid use disorder rate differences, mediated by buprenorphine providers/100,000 state population, decreased during the pandemic. States with telehealth policies for controlled substance prescribing had greater percentages of patients on medications for opioid use disorder (11.7%) than states without such policies (10.4%).

CONCLUSIONS

Monthly medications for opioid use disorder rates increased during the pandemic, with higher rates in men, White individuals, and residents of the Northeast region. States with policies permitting telehealth prescribing of controlled substances also had higher medications for opioid use disorder rates, supporting a future expansion of medications for opioid use disorder-related telehealth to improve access to care.

Real-World Dispensing of Buprenorphine in California during Prepandemic and Pandemic Periods

INTRODUCTION

The opioid overdose crisis in the United States has become a significant national emergency. Buprenorphine, a primary medication for individuals coping with opioid use disorder (OUD), presents promising pharmacokinetic properties for use in primary care settings, and is often delivered as a take-home therapy. The COVID-19 pandemic exacerbated the scarcity of access to buprenorphine, leading to dire consequences for those with OUD. Most existing studies, primarily focused on the immediate aftermath of the COVID-19 outbreak, highlight the challenges in accessing medications for opioid use disorder (MOUDs), particularly buprenorphine. However, these studies only cover a relatively short timeframe.

METHODS

To bridge this research gap, in our study, we utilized 33 months of California's prescription drug monitoring program (PDMP) data to provide insights into real-world buprenorphine dispensing trends since the onset of the pandemic from 2018 to 2021, focusing on outcomes such as patient counts, prescription volumes, prescriber involvement, days' supply, and dosage. Statistical analysis employed interrupted time series analysis to measure changes in trends before and during the pandemic.

RESULTS

We found no significant impact on patient counts or prescription volumes during the pandemic, although it impeded the upward trajectory of prescriber numbers that was evident prior to the onset of the pandemic. An immediate increase in days' supply per prescription was observed post-pandemic.

CONCLUSION

Our findings differ in comparison to previous data regarding the raw monthly count of patients and prescriptions. The analysis encompassed uninsured patients, offering a comprehensive perspective on buprenorphine prescribing in California. Our study's insights contribute to understanding the impact of COVID-19 on buprenorphine access, emphasizing the need for policy adjustments.

Trends in Use of Medication to Treat Opioid Use Disorder During the COVID-19 Pandemic in 10 State Medicaid Programs

Importance

Federal and state agencies granted temporary regulatory waivers to prevent disruptions in access to medication for opioid use disorder (MOUD) during the COVID-19 pandemic, including expanding access to telehealth for MOUD. Little is known about changes in MOUD receipt and initiation among Medicaid enrollees during the pandemic.

Objectives

To examine changes in receipt of any MOUD, initiation of MOUD (in-person vs telehealth), and the proportion of days covered (PDC) with MOUD after initiation from before to after declaration of the COVID-19 public health emergency (PHE).

Design, Setting, and Participants

This serial cross-sectional study included Medicaid enrollees aged 18 to 64 years in 10 states from May 2019 through December 2020. Analyses were conducted from January through March 2022.

Exposures

Ten months before the COVID-19 PHE (May 2019 through February 2020) vs 10 months after the PHE was declared (March through December 2020).

Main Outcomes and Measures

Primary outcomes included receipt of any MOUD and outpatient initiation of MOUD via prescriptions and office- or facility-based administrations. Secondary outcomes included in-person vs telehealth MOUD initiation and PDC with MOUD after initiation.

Results

Among a total of 8 167 497 Medicaid enrollees before the PHE and 8 181 144 after the PHE, 58.6% were female in both periods and most enrollees were aged 21 to 34 years (40.1% before the PHE; 40.7% after the PHE). Monthly rates of MOUD initiation, representing 7% to 10% of all MOUD receipt, decreased immediately after the PHE primarily due to reductions in in-person initiations (from 231.3 per 100 000 enrollees in March 2020 to 171.8 per 100 000 enrollees in April 2020) that were partially offset by increases in telehealth initiations (from 5.6 per 100 000 enrollees in March 2020 to 21.1 per 100 000 enrollees in April 2020). Mean monthly PDC with MOUD in the 90 days after initiation decreased after the PHE (from 64.5% in March 2020 to 59.5% in September 2020). In adjusted analyses, there was no immediate change (odds ratio [OR], 1.01; 95% CI, 1.00-1.01) or change in the trend (OR, 1.00; 95% CI, 1.00-1.01) in the likelihood of receipt of any MOUD after the PHE compared with before the PHE. There was an immediate decrease in the likelihood of outpatient MOUD initiation (OR, 0.90; 95% CI, 0.85-0.96) and no change in the trend in the likelihood of outpatient MOUD initiation (OR, 0.99; 95% CI, 0.98-1.00) after the PHE compared with before the PHE.

Conclusions and Relevance

In this cross-sectional study of Medicaid enrollees, the likelihood of receipt of any MOUD was stable from May 2019 through December 2020 despite concerns about potential COVID-19 pandemic-related disruptions in care. However, immediately after the PHE was declared, there was a reduction in overall MOUD initiations, including a reduction in in-person MOUD initiations that was only partially offset by increased use of telehealth.

Buprenorphine Treatment Episodes During the First Year of COVID: a Retrospective Examination of Treatment Initiation and Retention

BACKGROUND

During the COVID pandemic, overall buprenorphine treatment appeared to remain relatively stable, despite some studies suggesting a decrease in patients starting buprenorphine. There is a paucity of empirical information regarding patterns of buprenorphine treatment during the pandemic.

OBJECTIVE

To better understand the patterns of buprenorphine episodes during the pandemic and how those patterns compared to pre-pandemic patterns.

DESIGN

Pharmacy claims representing approximately 92% of all prescriptions filled at retail pharmacies in all 50 US states and the District of Columbia.

PARTICIPANTS

Individuals filling buprenorphine prescriptions indicated for treatment of opioid use disorder.

MAIN MEASURES

The number of active, starting, and ending buprenorphine treatment episodes March 13 to December 1, 2020, and the expected number of such episodes in 2020 based on the growth in treatment episodes from March 13 to December 1, 2019.

KEY RESULTS

The observed number of active buprenorphine episodes in December 2020 was comparable to the expected number, but new treatment episodes starting between March 13 and December 1, 2020, were 17.2% fewer than expected based on the 2019 experience. Similarly, the number of episodes that ended between March 13 and December 1, 2020, was 16.0% fewer than expected. Decreases from expected episode starts and ends occurred throughout the period but were greatest in the 2 months after the declaration of the public health emergency.

CONCLUSIONS AND RELEVANCE

Beneath the apparent stability of buprenorphine patient numbers during the pandemic, the flow of individuals receiving buprenorphine treatment changed substantially. Our findings shed light on how policy changes meant to support buprenorphine prescribing influenced prescribing dynamics during that period, suggesting that while policy efforts may have been successful in maintaining existing patients in treatment, that success did not extend to individuals not yet in treatment.

A Qualitative Exploration of the Functional, Social, and Emotional Impacts of the COVID-19 Pandemic on People Who Use Drugs

Since 2020, people who use drugs (PWUD) experienced heightened risks related to drug supply disruptions, contamination, overdose, social isolation, and increased stress. This study explored how the lives of PWUD changed in Philadelphia over a one-year period. Using semi-structured interviews with 20 participants in a Housing First, low-barrier medication for opioid use (MOUD) program in Philadelphia, the effects of the first year of the COVID-19 pandemic on the daily lives, resources, functioning, substance use, and treatment of PWUD were explored. Interviews were analyzed using a combination of directed and conventional content analysis. Six overarching themes emerged during data analysis: (1) response to the pandemic; (2) access to MOUD and support services; (3) substance use; (4) impacts on mental health, physical health, and daily functioning; (5) social network impacts; and (6) fulfillment of basic needs. Participants reported disruptions in every domain of life, challenges meeting their basic needs, and elevated risk for adverse events. MOUD service providers offset some risks and provided material supports, treatment, social interaction, and emotional support. These results highlight how there were significant disruptions to the lives of PWUD during the first year of the COVID-19 pandemic and identified critical areas for future intervention and policies.

Changes in Buprenorphine and Methadone Supplies in the US During the COVID-19 Pandemic

Importance

The opioid crisis has been exacerbated by the COVID-19 pandemic in the US, with concerns over major disruptions to medication treatment of opioid use disorder.

Objective

To investigate whether the COVID-19 pandemic was associated with disruption of buprenorphine and methadone supplies in the US.

Design, Setting, and Participants

This repeated cross-sectional study used ARCOS (Automated Reports and Consolidated Ordering System) data, which monitor the flow of controlled substances in the US, from January 1, 2012, through June 30, 2021. Manufacturers and point of sale or distribution at the dispensing or retail level, including hospitals, retail pharmacies, clinicians, midlevel clinicians, and teaching institutions, were included in the analysis.

Exposures

COVID-19 pandemic.

Main Outcomes and Measures

Quarterly supplies of buprenorphine and methadone per capita in milligrams.

Results

The per capita supply of methadone dropped from 13.2 mg in the first quarter of 2020 to 10.5 mg in the second quarter of 2020, whereas the per capita supply of buprenorphine increased from 3.6 mg to 3.7 mg in the same period. The per capita supply of methadone declined 20% (-2.7 mg) in the second quarter of 2020 compared with the first quarter of 2020, and the supply had not returned to 2019 levels as of June 2021, whereas the supply of buprenorphine per person increased consistently during the same period. There were considerable state disparities in the reduction of the methadone supply during the pandemic, with many states experiencing pronounced per capita supply decreases, including reductions as great as 50% in New Hampshire and Florida. These decreases in per capita methadone supply were not compensated by proportional increases in the per capita buprenorphine supply (linear fit, 0.17 [95% CI, -0.43 to 0.76]; P = .47).

Conclusions and Relevance

This cross-sectional study of buprenorphine and methadone supplies during the COVID-19 pandemic found a pronounced decline in the methadone supply but no disruption to the buprenorphine supply. Future research is needed to explain the pronounced state disparities in the methadone supply.

Impact of reduced restrictions on buprenorphine prescribing during COVID-19 among patients in a community-based treatment program

Background

Medications such as buprenorphine are considered the gold standard for the treatment of opioid use disorders. This study aimed to determine whether less restrictive buprenorphine prescribing practices during the COVID-19 pandemic impacted retention in and adherence to buprenorphine among patients accessing treatment from 2018-2020 at a community-based syringe services program.

Methods

In this retrospective cohort study, we compared retention in treatment before and during the COVID-19 pandemic. Then, with relaxed restrictions acting as the intervention in a natural experiment, we conducted a sub-analysis of "continuity participants" who accessed treatment services both before and during the COVID-19 period. Records of 418 historical control patients treated with buprenorphine before COVID-19 were compared to 88 patients enrolled during COVID-19 (n=43 remote telemedicine and n=45 remote provider with patient on-site). Cox proportional hazards regressions were used to assess risk factors for treatment discontinuation. The sub-analysis used proportion of days covered (PDC) differences before and during COVID-19 (n=164) for a paired analysis in a nonparametric bootstrap test.

Results

The risk of discontinuation was 71% lower in those accessing remote telemedicine during COVID-19 (HR=0.29; CI: 0.18, 0.47) and 51% lower in those accessing their remote provider onsite during COVID-19 (HR=0.49; CI:0.31, 0.77), compared to the historical control group. The average PDC did not significantly differ before and during COVID-19 (difference=2.4%; CI:-0.6%, 5.3%).

Conclusions

The risk of discontinuing treatment was lower in both COVID-19 treatment groups compared to historical controls. Less restrictive buprenorphine prescribing guidelines during COVID-19 led to improved retention in care over 6-months.

Changes in transmucosal buprenorphine utilization for opioid use disorder treatment during the COVID-19 pandemic in Kentucky

PURPOSE

With surging opioid-involved overdoses, maintaining access to opioid use disorder (OUD) treatment is critical during the COVID-19 pandemic. We examined changes in transmucosal buprenorphine prescribing for OUD treatment in Kentucky after the national COVID-19 emergency declaration, with a focus on rural-urban differences.

METHODS

Using 2019-2020 prescription monitoring data, we performed segmented regression analysis for an interrupted time series design to evaluate changes in weekly rates (per 100,000 residents) of dispensed prescriptions, unique individuals with dispensed prescriptions, and average days' supply for dispensed prescriptions of transmucosal buprenorphine.

FINDINGS

The weekly rates of dispensed prescriptions and unique individuals with dispensed prescriptions were higher for rural residents than urban residents. After the national COVID-19 emergency declaration, rural and urban residents experienced similar immediate drops in the rate of dispensed prescriptions (rural -33.4; urban -24.3) and unique patients with dispensed prescriptions (rural -25.0; urban -17.1), followed by similar sustained increases. Both measures surpassed the prepandemic levels in mid-June 2020. Patients residing in urban areas received averagely longer prescriptions at baseline (urban: 11.0 days; rural: 10.5 days). The average weekly days' supply increased in the week after the national emergency declaration, but the estimated increase was higher (P = .004) for urban (0.8 days) versus rural (0.5 days) residents.

CONCLUSIONS

Transmucosal buprenorphine utilization increased during the COVID-19 pandemic after experiencing interruption during the initial weeks of the pandemic. Future studies should evaluate the contribution of the relaxed telemedicine buprenorphine prescribing regulations during the COVID-19 national emergency on initiation and maintenance of buprenorphine treatment.

Subsequent Buprenorphine Treatment Following Emergency Physician Buprenorphine Prescription Fills: A National Assessment 2019 to 2020

STUDY OBJECTIVE

Buprenorphine treatment for opioid use disorder provided in the emergency department with subsequent buprenorphine treatment by community prescribers is associated with improved outcomes, but the frequency with which this occurs is unknown. We examined the rates of subsequent buprenorphine treatment for buprenorphine-naïve individuals filling buprenorphine prescriptions from emergency physicians and initiated buprenorphine treatment and how such rates varied before and during the coronavirus disease 2019 (COVID-19) pandemic.

METHODS

Using pharmacy claims capturing an estimated 92% of prescriptions filled at US retail pharmacies, we identified buprenorphine prescriptions filled between February 1, 2019, and November 30, 2020, written by emergency physicians. In this observational study, we calculated the rate at which patients subsequently filled buprenorphine prescriptions from other nonemergency clinicians, the frequency with which subsequent filled prescriptions were from different types of prescribers, and the changes in the rates of subsequent prescriptions following the declaration of the COVID-19 public health emergency.

RESULTS

We identified 22,846 prescriptions written by emergency physicians and filled by buprenorphine-naïve patients. They were most commonly paid for by Medicaid and were in metropolitan counties; 28.5% of patients subsequently filled buprenorphine prescriptions written by other clinicians. Adult primary care physicians and advanced practice providers (eg, physician assistants and nurse practitioners) were responsible for most of the subsequent prescriptions. The rates of subsequent prescriptions were 3.5% lower after the COVID-19 public health emergency declaration.

CONCLUSION

The majority of patients filling buprenorphine prescriptions written by emergency physicians do not subsequently fill prescriptions written by other clinicians, and the rates of subsequent prescriptions were lower after the declaration of the COVID-19 public health emergency. These findings highlight the need for a system of care that improves buprenorphine treatment continuity of care for patients with opioid use disorder from emergency settings to community treatment providers.
