The COVID-19 pandemic occurred as the public health response to the U.S. opioid crisis was gaining momentum (
1,
2). The pandemic strained the U.S. health care system, resulting in insufficient access to opioid use disorder treatment and contributing to increased incidence of opioid use and overdose (
3,
4). Concurrently, the pandemic created opportunities for innovation in delivering general, mental, and behavioral health care (
5). Across the country, health care facilities reported adaptations to care delivery—such as use of telehealth, remote management, and other workflow changes—to limit treatment disruptions and to minimize the risk for COVID-19 transmission among staff and patients (
6–
8). Simultaneously, many facilities reported drastic changes in patient demand and engagement with services as physical distancing guidelines were implemented (
9,
10). Within the context of COVID-19–related disruptions and innovations, in this study we explored adaptations to care delivery among U.S. outpatient practices serving patients with opioid use disorder during the pandemic. We also examined whether these practices experienced changes in patient demand and engagement during this period.
Outpatient care has an increasingly central role in diagnosing and managing opioid use disorder (
11). Office-based providers of medications for opioid use disorder (MOUD) prescribe buprenorphine and can administer extended-release formulations of buprenorphine and naltrexone. Treatment in these settings has historically involved engaging patients through in-person encounters (
12). Social distancing protocols for COVID-19 disrupted such in-person treatment and led to easement of federal regulations to facilitate MOUD access. Importantly, the U.S. Drug Enforcement Administration (DEA) issued temporary regulations permitting physicians and other authorized practitioners to prescribe buprenorphine via videoconferencing or telephone visits to new and existing patients experiencing opioid use disorder during the COVID-19 public health emergency in the United States (
13,
14).
Despite the regulatory easements, most individuals with opioid use disorder remain untreated or undertreated (
15). This treatment shortfall warrants deeper understanding of measures taken to promote MOUD access, especially during a public health disaster. The Addiction Medicine Practice–Based Research Network (AMNet)—an innovative learning and research system developed to help understand management of opioid use disorder in office-based practices and outpatient treatment programs (
16,
17)—represents one such approach. As part of AMNet, we conducted a brief recruitment survey inquiring about general practice characteristics, patient demand and engagement, as well as adaptations to care delivery during the COVID-19 pandemic. In this study, we delineated the survey results from a period before a COVID-19 vaccine was available, that is, in June–November 2020. Given the duration of the pandemic, and continued public health guidance to exercise caution with travel and social contact, we expected that outpatient practices and their providers would report continued adaptations to care delivery. We also expected that most respondents would report changes in patient demand and engagement during this time.
Methods
Study Design
The AMNet Recruitment Survey is an online survey of medical practices and their providers who provide outpatient medication treatment focused on opioid use disorder within non–opioid treatment programs for substance use disorders. Practices eligible for the survey could have physicians, nurse practitioners, physician assistants, and nonprescribing mental health providers. The survey captured information on practice characteristics, practices’ adaptations to care delivery for opioid use disorder since the declaration of the COVID-19 public health emergency, as well as the impact of the pandemic (
18) on patient demand and engagement. The survey was implemented after the DEA issued regulatory easements regarding telehealth MOUD management.
Recruitment and Sampling
Potential respondents completed an online survey, via Alchemer (
https://www.alchemer.com), that was distributed broadly by the American Psychiatric Association (APA) and by the American Society of Addiction Medicine through their promotional channels (i.e., newsletters, e-mails, social media, membership Listservs, and advertisements in APA’s e-newsletter,
Psychiatric News). Postcards advertising the survey were mailed to buprenorphine providers certified by the Substance Abuse and Mental Health Services Administration who were eligible to treat ≥100 patients. AMNet investigators also publicized the survey during presentations at professional conferences. For this study, we purposively sampled physician and nonphysician (nurse practitioners and physician assistants) prescribers. The eligible study sample (N=569) was drawn from a total of 643 respondents as of November 22, 2020 (see Figure S1 in the
online supplement to this article).
Measures
The AMNet Recruitment Survey (
https://bit.ly/3gSHOHq) comprised two sections. Section 1 inquired about general practice characteristics, including location (urban, rural, or suburban), practice type (solo, group, community health or mental health center, state-certified substance use treatment program, or other), types of clinicians (physician, nurse practitioner, physician assistant, therapist, or counselor), whether the practice was covered by federal alcohol and drug confidentiality regulations (part 2 of Title 42 of the Code of Federal Regulations [42 CFR]: yes vs. no), and whether the practice provided buprenorphine prescriptions (yes vs. no), extended-release naltrexone (XR-NTX) for opioid use disorder (yes vs. no), and XR-NTX for alcohol use disorder (yes vs. no). The last question in section 1 of the survey asked respondents whether they were willing (yes vs. no) to answer questions about the practice’s experience during the COVID-19 pandemic. Only respondents who answered yes to the last question were asked to complete section 2.
Section 2 of the survey was adapted from a similar survey (
18). Respondents were asked whether MOUD adaptations had been made (yes vs. no) in response to the COVID-19 pandemic and, if so, what the adaptations were (i.e., changes to urine drug screening [UDS], visit type, buprenorphine prescription duration [e.g., weekly or more], refill frequency, and injectable naltrexone administration). Respondents also were asked whether the practice’s patients had been “impacted by COVID-19” (yes vs. no) and, if so, what the impacts were (increase or decrease in demand for visits, preference for virtual vs. in-person MOUD appointments, difficulty engaging or retaining patients in care, and changes in treatment retention). The adaptation and impact questions allowed respondents to select multiple responses.
Main Variables of Interest and Study Approval
For this study, the primary dependent variables were MOUD adaptation, UDS adaptation, and impact on patients. Practice characteristics (e.g., practice location and type, prescriber type, and 42 CFR part 2) were independent variables that were used to examine factors associated with MOUD adaptation, UDS adaptation, and patient impact. Prescriber type was physician versus nonphysician prescribers (nurse practitioners and physician assistants). The survey was approved by the APA Institutional Review Board.
Analysis
Frequency distributions were calculated for practice and prescriber characteristics, adaptations to care delivery, and changes in patient demand and engagement. Further descriptive analyses were conducted to characterize changes to MOUD visits, MOUD management, UDS practices, and patient demand and engagement. Bivariate analyses were used to assess differences in general practice characteristics by MOUD adaptation (yes vs. no), UDS adaptation (yes vs. no), and patient impact (yes vs. no). These bivariate results, including unadjusted logistic models, informed the decision which variables to include in stepwise multivariable logistic regression models in order to explore whether general practice and prescriber characteristics predicted MOUD adaptation, UDS adaptation, and patient impact. Because of high correlation between practices prescribing XR-NTX for alcohol use disorder and those prescribing XR-NTX for opioid use disorder (Spearman correlation coefficient ρ=0.83, p<0.001), these two variables were not included in the same multivariable adjusted models. Using a 26:1 ratio of those who prescribed buprenorphine (N=494) relative to those who did not (N=19), we conducted post hoc sensitivity analyses with case-control designs (i.e., 1:2 and 1:3 ratios of cases [nonprescribers] to controls [prescribers]) on the basis of buprenorphine prescribing (no vs. yes) to assess the robustness of findings across all outcomes. All analyses were conducted with SAS, version 9.4, with α=0.05 as the cutoff value for statistical significance.
Discussion
During the COVID-19 pandemic, health care facilities adapted care delivery to continue providing treatment while reducing the risk for viral transmission. This study presents the results of a brief online survey of U.S. outpatient practitioners describing the impact of the pandemic on the treatment of patients with opioid use disorder before COVID-19 vaccines became available. Most practices reported adaptations to MOUD management practices, including UDS adaptations, in response to the pandemic. Most respondents who reported making such MOUD adaptations were buprenorphine prescribers. Among those who made the adaptations, many offered at least some virtual visits and reduced the frequency of UDS for established patients. These findings were similar to those of a study (
18) of adaptations for opioid use disorder treatment in primary care practices in California, where >90% of participating clinics reported making practice adaptations, including prescribing buprenorphine for longer durations (65%) and reducing UDS (67%). Our findings are also supported by those of a qualitative study (
19) of MOUD providers in New Jersey who hoped that the temporary regulatory changes to permit remote prescription of buprenorphine would become permanent.
Our respondents’ reports of increased virtual visits reflected the regulatory telehealth easements implemented for MOUD during the COVID-19 pandemic. In another recent survey (
20) of opioid use disorder treatment clinicians, one-third reported that they had initiated remote buprenorphine induction during the pandemic. In that study, predictors of this MOUD adaptation were higher patient volume, previous telehealth prescribing to established MOUD patients, and closure of the practice facilities because of the pandemic.
Most practices in our study reported that the COVID-19 pandemic had affected their patients. The practices providing XR-NTX for opioid use disorder reported impacts of the pandemic on patients’ treatment, likely because XR-NTX is administered via intramuscular injection, which cannot be done remotely. This result paralleled other findings (
21) indicating that, compared with buprenorphine, XR-NTX was provided less frequently during the pandemic. These findings indicate an important barrier to access for patients receiving XR-NTX during the earlier stages of the pandemic.
Most survey respondents reported having virtual-only initial visits or a combination of virtual and in-person initial visits during the COVID-19 pandemic, which likely reflected the more flexible regulatory environment created by the pandemic. Before the pandemic, telehealth was underused by patients with substance use disorders. For example, a population-based, retrospective study (
22) of 2010–2017 claims data estimated that the rate of telehealth visits for substance use disorders was only three visits per 1,000 patients with any substance use disorder diagnosis in 2017. Among individuals diagnosed as having opioid use disorder, the study estimated that <1% had received a telehealth visit in a given year. Expanded virtual offerings for opioid use disorder care, made possible by regulatory changes in response to the pandemic, likely increased access to care for all patients but especially for those facing transportation or time barriers (
23). In our survey, 45% of the respondents reported that their patients preferred virtual visits compared with 18% who reported that their patients preferred in-person visits.
Service continuity and patient safety are key considerations for people with opioid use disorder, especially when care and supervision are received remotely (
24–
26). Our findings of patients’ preference for virtual visits suggest a favorable risk-benefit profile for virtual care (
27). However, in-person interactions can support patient engagement and accountability for desired health behaviors, and receipt and effectiveness of care may also be influenced by the engagement strategy and treatment environment (
28). Because 30% of practices reported more difficulty in engaging patients, and 14% reported less difficulty, comparative effectiveness research on varied approaches to virtual engagement would be valuable. Such research could include examining asynchronous care, digital therapeutics, remote drug testing, and implications of reducing telehealth or telephone prescribing for buprenorphine (
29).
This study had several limitations. Initially, data were collected to determine practices’ eligibility to participate in AMNet, in which practices had to have at least 100 patients, of whom at least 26% were treated for opioid use disorders. Consequently, our findings may not be generalizable to all U.S. outpatient practices. We did not identify survey respondents by practice; therefore, some group practices may have been overrepresented (i.e., if multiple practitioners from the same group practice responded). The study was also limited by the collection of data before the availability of COVID-19 vaccines in the United States. Some practices that shifted to telehealth during the early phase of the pandemic may have returned to in-person treatment for some or all patients after such vaccines became available.
Nonetheless, our findings are valuable, because further disruptions to care are likely, such as those due to Hurricane Sandy and the September 11, 2001, tragedy (
30–
32). A study exploring practice adaptations over time would provide information about long-term patterns and sustainability. The rapid changes to care delivery by health care facilities and systems in response to the pandemic have created natural experiments in which to study these issues (
33). However, our survey was intentionally brief to reduce time burden, and the survey completion rate was high. Although we used a convenience sampling method, we obtained results from a large sample of practices representing different types of clinicians working in varied outpatient settings across the country.
