Both treatments are highly regulated, with prepandemic requirements for in-person care. COVID-19 may have resulted in barriers to accessing in-person care through disruptions in care delivery. However, there were also opportunities for improved access to telemedicine visits through policy changes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aims to evaluate changes in health care and telemedicine use during the COVID-19 pandemic among patients using buprenorphine for OUD and long-term opioid therapy for chronic pain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We used administrative claims data for commercially insured and Medicare Advantage patients from the OptumLabs Data Warehouse. We included patients using buprenorphine for OUD or long-term opioid therapy for chronic pain compared to patients with another chronic condition without similar prescribing restrictions: serious mental illness. We evaluated changes in in-person and telemedicine care by comparing rates of services by physician specialty, type of service, and the percentage of visits through telemedicine. Changes in usage were measured using a difference-in-differences approach with Poisson regression. The results are presented as incident rate ratios (IRR).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We found declines in in-person visits in April 2020 across the buprenorphine, chronic opioids, and serious mental illness cohorts. The largest declines were for specialties that rely on in-person treatment, such as emergency medicine (IRR range 0.60-0.62), orthopedics (IRR 0.48-0.52), cardiology (IRR 0.64-0.78), and oncology (IRR 0.77-0.81). In contrast, there were smaller declines for specialties that could more easily transition to telemedicine, namely family practice (IRR 0.80-0.92), mental health (IRR 0.92-1.01), and pain medicine (IRR 0.87-1.08). The percentage of telemedicine visits for these specialties ranged from 30% to 51% in the period. There were also large declines for specific services, including emergency medicine (IRR 0.53-0.89), physical therapy (IRR 0.24-0.72), and new office visits (IRR 0.38-0.64). By January 2022, usage was similar to prepandemic levels, but the percentage of telemedicine visits remained elevated for family practice (10%-14%), mental health (34%-43%), and pain medicine (11%-15%) through January 2022. The results were similar across the cohorts, although in April 2020 there was a modest decrease (IRR 0.87) for pain medicine in the serious mental illness cohort, but the differences were not significant for the buprenorphine (IRR 1.08) and chronic opioids (IRR: 0.99) cohorts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings highlight the value of telemedicine to maintain access among people at risk for poor outcomes if care is interrupted. While flexibilities in the regulation of telemedicine services that arose during the pandemic have been temporarily extended multiple times, they are set to expire in 2025 without further action. Making these changes to telemedicine regulation permanent may benefit vulnerable patient populations who face access to care challenges.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/66596","type":"journal-article","created":{"date-parts":[[2025,6,19]],"date-time":"2025-06-19T15:35:08Z","timestamp":1750347308000},"page":"e66596","source":"Crossref","is-referenced-by-count":0,"title":["Health Services Usage in Patients Receiving Buprenorphine for Opioid Use Disorder or Long-Term Opioid Therapy for Chronic Pain: Retrospective Cohort Study"],"prefix":"10.2196","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3190-7740","authenticated-orcid":false,"given":"Samuel T","family":"Savitz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3184-5834","authenticated-orcid":false,"given":"Maria A","family":"Stevens","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8385-3417","authenticated-orcid":false,"given":"Bidisha","family":"Nath","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3833-1871","authenticated-orcid":false,"given":"Gail","family":"D'Onofrio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6509-9537","authenticated-orcid":false,"given":"Edward R","family":"Melnick","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3854-6810","authenticated-orcid":false,"given":"Molly M","family":"Jeffery","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,6,19]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2020.21476"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1001\/jamanetworkopen.2020.24984"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1377\/hlthaff.2020.01786"},{"key":"ref4","author":"Cameron, P","year":"2015","journal-title":"Textbook of Adult Emergency Medicine"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1001\/jamainternmed.2016.5057"},{"key":"ref6","unstructured":"Medicare Telemedicine Health Care Provider Fact SheetCMS20202020-03-07https:\/\/www.cms.gov\/newsroom\/fact-sheets\/medicare-telemedicine-health-care-provider-fact-sheet"},{"key":"ref7","unstructured":"FAQs on availability and usage of telehealth services through private health insurance coverage in response to Coronavirus diseaseCMS20202020-03-24https:\/\/www.cms.gov\/files\/document\/faqs-telehealth-covid-19.pdf"},{"key":"ref8","unstructured":"S. 3548 - Coronavirus Aid, Relief, and Economic Security (CARES) ActTaxnotes20202020-03-19https:\/\/www.taxnotes.com\/research\/federal\/legislative-documents\/proposed-legislation\/s-3548-coronavirus-aid-relief-and-economic-security-cares-act\/2c9nz"},{"key":"ref9","unstructured":"America's Health Insurance PlansTelehealth Coverage During the COVID-19 Pandemic20202022-03-17https:\/\/www.ahip.org\/resources\/telehealth-coverage-during-the-covid-19-pandemic"},{"key":"ref10","unstructured":"Drug Enforcement Administration (DEA).
