Study highlights underuse of buprenorphine option
“Our study shows that buprenorphine initiation rates have been flat since the end of 2018 and that rates of 180-day retention in buprenorphine therapy have remained low throughout 2016-2022,” Dr. Chua told this news organization. “Neither of these findings are particularly surprising, but they are disappointing,” he said. “There were a lot of policy and clinical efforts to maintain and expand access to buprenorphine during the COVID-19 pandemic, such as allowing buprenorphine to be prescribed via telehealth without an in-person visit and eliminating training requirements for the waiver that previously was required to prescribe buprenorphine.
“The fact that buprenorphine initiation and retention did not rise after these efforts were implemented suggests that they were insufficient to meet the rising need for this medication,” he said.
The current study “adds to a growing body of research suggesting that clinicians are not maximizing opportunities to initiate buprenorphine treatment among patients with opioid addiction,” Dr. Chua said. He cited another of his recent studies in which 1 in 12 patients were prescribed buprenorphine within 30 days of an emergency department visit for opioid overdose from August 2019 to April 2021, but half of patients with emergency department visits with anaphylaxis were prescribed anepinephrine auto-injector.
“My hope is that our new study will further underscore to clinicians how much the health care system is underusing a critical tool to prevent opioid overdose deaths,” he said.
The federal government’s recent elimination of the waiver needed to prescribe buprenorphine may move the needle, but to what degree remains to be seen, Dr. Chua added. “It is possible this intervention will be insufficient to overcome the many other barriers to buprenorphine initiation and retention, such as stigma about the drug among clinicians, patients, and pharmacists,” he said.
Lack of education remains a barrier to buprenorphine use
The current study is important to determine whether attempts to increase buprenorphine initiation and treatment retention are working, said Reuben J. Strayer, MD, director of addiction medicine in the emergency medicine department at Maimonides Medical Center, New York, in an interview.
Dr. Strayer was not involved in the current study, but said he was surprised that initiation of buprenorphine didn’t decrease more dramatically during the pandemic, given the significant barriers to accessing care during that time.
However, “efforts to increase buprenorphine initiation and retention have not been sufficiently effective,” Dr. Strayer said. “The rise of fentanyl as a primary street opioid, replacing heroin, has dissuaded both patients and providers from initiating buprenorphine for fear of precipitated withdrawal.”
The elimination of the DATA 2000 (X) waiver was the removal of a potential barrier to increased buprenorphine use, said Dr. Strayer. “Now that the DATA 2000 (X) waiver has been eliminated, the focus of buprenorphine access is educating primary care and inpatient providers on its use, so that patients with OUD [opioid use disorder] can be treated, regardless of the venue at which they seek care,” he said.
Looking ahead, “The priority in buprenorphine research is determining the most effective way to initiate buprenorphine without the risk of precipitated withdrawal,” Dr. Strayer added.
The study was supported in part by the Benter Foundation, the Michigan Department of Health and Human Services, and the Susan B. Meister Child Health Evaluation and Research Center in the department of pediatrics at the University of Michigan. Dr. Chua was supported by the National Institute on Drug Abuse. Dr. Strayer has disclosed no relevant financial relationships.
