A study at Columbia University Mailman School of Public Health found that long-term buprenorphine treatment is associated with improvements in health care outcomes. Compared to individuals who discontinued buprenorphine, those with continuous treatment had significantly lower rates of prescription opioid use and opioid-related events, including medically treated overdoses in the follow-up period. The results are published in the May issue of the journal Health Affairs.

"Buprenorphine is an effective medication for the treatment of opioid addiction, yet until now studies were not designed to establish a minimum duration of treatment for opioid use disorder needed to achieve improved clinical outcomes," said Hillary Samples, Ph.D., postdoctoral research fellow in the Department of Epidemiology, Columbia University Mailman School of Public Health. "As a result of limited evidence, and care guidelines set potentially restrictive treatment standards."

The researchers analyzed health insurance claims data to compare patients with continuous treatment to those who discontinued 6-9 months after initiating medication with the goal of extending evidence from clinical trials, which are typically limited to 3 to 6-month periods. In addition, the National Quality Forum defines 180 days (6 months) as the minimum duration of pharmacotherapy for treatment, and quality measures are often used by federal and state agencies or health plans to set treatment standards.

Compared to 4,433 adults who discontinued buprenorphine 6-9 months after beginning treatment, individuals with continuous treatment had significantly of all-cause inpatient (-52%) and emergency department (-26%) services, opioid-related hospital services (-128%), overdose events (-173%), and opioid prescriptions (-120%) as well as a significantly lower rate of prescription opioid use (-124%) in the follow-up period than in the treatment period.

The greatest decreases were found for overdose events, -related inpatient and services and prescription opioids use. "The pattern of results indicates that longer-term buprenorphine treatment more effectively protects patients from adverse clinical outcomes," said Samples.

"Overall, our findings suggest a need for broader efforts to increase long-term access to care and extend standards and guidelines for minimum treatment duration," noted Samples. "While guidelines can lead to improvements in care and patient outcomes, they can also have unintended consequences, such as forming the basis for managed care practices that limit access to longer-term treatment."
