‘A window of vulnerability’
Authors of an accompanying editorial note the study “adds weight” to the evidence that OAT is a “lifesaving” treatment.
“It’s critical to recognize that transitions in and out of care are vulnerable periods” when it comes to suicide, the coauthor of the editorial, Paul S. Nestadt, MD, department of psychiatry and behavioral sciences, Johns Hopkins University, Baltimore, told this news organization.
Official suicide statistics may not reflect the entire story, as many deaths that occur because of overdose after treatment cessation are not counted as suicides, he said. “It can be difficult for medical examiners to determine if an overdose was intentional or not,” Dr. Nestadt added.
After treatment has been established, physicians “would be wise to delay treatment cessation” until the patient is in a stable condition and can be closely followed by mental health professionals, the editorialists note.
“We must consider the month following OAT cessation to be a window of vulnerability, not just for relapse but also for suicide,” they write.
The finding that patients prescribed OAT have such a high rate of suicide, compared with the general population, is “troubling” and “highlights the importance of interventions which address both opioid use and suicide risk,” they add.
The editorialists point out the median treatment period of 84 days is less than what is generally recommended, raising the question of whether longer treatment might lower suicide risk after treatment discontinuation.
They also emphasized the need for further study to test potential suicide prevention interventions in the period after treatment cessation.
Dr. Nestadt added the new findings are “quite generalizable outside of the U.K.” and referred to similar studies carried out in Australia and elsewhere.
The study was funded by the Medical Research Council. Dr. Padmanathan was a coapplicant on an a grant awarded to University of Bristol by Bristol and Weston Hospital Charity focusing on suicide prevention for patients presenting to the emergency department with self-harm and harmful substance use. Dr. Nestadt has reported no relevant financial relationships.
