Unlimited, immediate access to opioid agonist treatment with methadone for patients with opioid use disorder offers drastic cost savings and greater health benefits compared with the standard of care, according to a study published in Annals of Internal Medicine.
“Limited access to opioid agonist treatment with either methadone or buprenorphine is a major impediment to reducing the societal burden of the current prescription opioid and heroin use epidemic,” Emanuel Krebs, MA, from British Columbia Centre for Excellence in HIV/AIDS, Canada, and colleagues wrote.
“Only one in five of the nearly 2.4 million Americans with an opioid use disorder received treatment in 2015,” they added.
Krebs and colleagues conducted a model-based cost-effectiveness analysis to investigate the benefits and costs of immediate access to opioid agonist treatment with methadone for all patients presenting at California’s publicly funded treatment facilities with opioid use disorder compared with the observed standard of care. The standard of care included time-limited medically supervised withdrawal and comprised 54.3% of those with opioid use disorder.
The researchers identified data on drug treatment and criminal justice system engagement for California from 2006 to 2010 using linked population-level administrative databases. They compared these data with health benefits that were measured with accumulated quality-adjusted life-years and lifetime costs for patients starting opioid use disorder treatment in 2014 using a computer model.
The model estimated that unlimited, immediate access to opioid agonist treatment could save up to $3.8 billion over the lifetimes of the patients in this cohort. In addition, the researchers found that patients receiving immediate opioid agonist treatment saved a total lifetime cost of $78,257 per person and raised QALYs by 0.42 per person, compared with observed standard of care.
These findings were robust according to sensitivity analyses, which revealed that 99.6% of 2,000 simulations demonstrated lower costs and more QALYs with immediate opioid agonist treatment.
“Immediate access to [opioid agonist treatment] for patients presenting for opioid use disorder treatment is more effective and less costly than the observed standard of care in publicly funded treatment facilities in California, and the model-projected savings can inform strategic investments for public health policy,” Krebs and colleagues concluded.
“Our findings further underline the need for widespread and unencumbered access to evidence-based treatment of opioid use disorder to reduce the burden to society of the current prescription opioid and heroin use epidemic,” they added.
In an accompanying editorial, Jeanette M. Tetrault, MD, and David A. Fiellin, MD, both from the Yale University School of Medicine, wrote that these data further validate the efficacy of opioid agonist treatment and prove that health care resources should focus less on medically managed withdrawal and more on outpatient opioid agonist treatment.
“Threats to health care funding may have lasting consequences, especially if lawmakers do not heed the most science-based and policy applicable data as decisions are being made,” they warned. – by Alaina Tedesco
