New study shows increased accessibility to methadone treatment through primary care decreases spread of HIV
Vancouver, BC [August 10, 2015] - As British Columbia's methadone maintenance program comes under provincial review, a new study by the BC Centre for Excellence in HIV/AIDS (BC-CfE) highlights
major benefits of methadone in Vancouver. The study, published in the prestigious medical journal
The Lancet HIV shows a link between increased access to methadone for injection drug users and
a decrease in the spread of HIV in this population.
While methadone is restricted in many areas of the world, British Columbia's program
is unique in that medication can be prescribed by primary care physicians and dispensed
through community pharmacies similar to other medications.
The study, Effect of low-threshold methadone maintenance therapy for people who inject
drugs on HIV incidence in Vancouver, BC, Canada: an observational study, examined
the effect of methadone maintenance therapy on HIV rates, using data from the
U.S. National Institutes of Health-funded Vancouver Injection Drug Users
“Those individuals in the study who were not prescribed methadone were almost four
times more likely to become HIV positive,” said study lead Dr. Keith Ahamad, an
addiction medicine physician and BC-CfE Clinician Scientist. “This study not
only increases the evidence base for methadone to treat opioid use
disorders and decrease the spread of HIV, it also highlights the
importance of primary care physicians in treating substance use disorders.”
"These findings are particularly important in light of recent outbreaks of HIV
infection among opioid users where methadone treatment is either illegal or
difficult to access such as recent outbreaks in the U.S. and Europe,”
said study senior author Dr. Evan Wood, the medical director of
addiction services at Vancouver Coastal Health and Providence
Health Care. “While our team universally agrees with the
need to improve British Columbia's methadone program,
the study reinforces the benefits of low threshold
methadone on public health goals such as reducing the spread of HIV.”
Data was derived from 1,639 HIV-negative injection drug users, recruited between
May 1996 and May 2013. To qualify, participants had to test HIV negative at the
start of the study and to return to the study office to assess for newly
acquired HIV. During this time, 138 individuals became HIV positive, the
vast majority not taking methadone during the study period.
Dr. Ahamad added, “These findings reinforce the opportunity to improve addiction
treatment by improving the overall approach to treating opioid addiction in B.C.
This requires improvement to the methadone program, but also expanding the
diversity of evidence-based treatment options for people struggling with
