Physicians who fail to help patients suffering from addiction blame their institutions and their own limitations in skill, knowledge, available brainpower, and faith that interventions will help patients, a systematic review found.
Researchers analyzed 283 international studies with data from 66,732 physicians who were asked about their reluctance to address addiction treatment and substance use. Of the studies, 61.5% cited lack of knowledge as a factor, 61.1% cited lack of institutional support, 60.1% cited lack of skills, 48.1% cited lack of available brainpower, and 46.6% cited lack of expectations of benefit, reported Wilson M. Compton, MD, deputy director of the National Institute on Drug Abuse, Baltimore, and colleagues, in JAMA Network Open.
Lack of Priority in Addiction Care
In an interview, Sarah Wakeman, MD, senior medical director for substance use disorder at Mass General Brigham, Boston, questioned the lack of priority given to addiction care. "Many of the perceived barriers that physicians cite for why they don't offer addiction treatment exist for many types of health conditions we routinely manage," said Wakeman, who's familiar with the findings but didn't take part in the study. "Yet we as physicians would never opt out of treating diabetes or heart disease. So why is it acceptable to opt out of treating addiction?"
As the review notes, an estimate suggests that more than 46 million people in the United States were diagnosed with substance abuse disorder in the past year, and misuse of alcohol and illegal drugs costs more than $442 billion a year. However, few people with addiction get treatment — estimated at only 6.3% in 2021 — and screening rates are low.
According to its authors, the review's goal is to summarize studies into barriers to evidence-based addiction strategies such as screening, referral to treatment, medications, and behavioral interventions.
The researchers analyzed 283 studies from 1960 to 2021, mainly (64.0%) from 2010 to 2021, with only a few (2.7%) from before 2000. Most (60.1%) were survey-based, and most (59.4%) were from the United States. The studies mainly examined alcohol, opioid, and tobacco addiction.
Challenges in Treating Addiction
The studies pinpointed various challenges in the treatment of people with addiction. On the institution front, they noted obstacles such as lack of trained staff, prior authorization hassles, lack of insurance coverage, and "acceptance of addiction interventions by staff," according to the review. In terms of knowledge and skill, "knowledge was more deficient for treatment than for screening or diagnosis and for drug use more than for alcohol or tobacco use."
Available brainpower "was not often characterized beyond a general sense of overwhelm with clinical tasks (eg, 'just too busy') and the need to prioritize patients' competing needs," the review stated.
The review authors wrote that "other reasons for reluctance (eg, negative social influences, negative emotions toward people who use drugs, and fear of harming the relationship with the patient by discussing substance use) could each be viewed as manifestations of stigma associated with substance use disorder and its treatment."
The review identified limitations such as "inconsistent use of terms" across studies and lack of detail in some studies about participation by the "audience of focus." Additionally, the authors noted that the medical treatments for addiction have evolved over the past several decades, as has the drug market.
Wakeman said the review is well done with unsurprising results. "It is helpful to understand what physicians perceive the barriers to be so that further interventions can be designed to surmount those barriers, such as skills training or educational interventions," she said.
Going forward, she said, "we need to end substance use disorder exceptionalism and stop approaching addiction treatment as if it is something different from the rest of healthcare."
In an interview, Michael L. Barnett, MD, MS, associate professor of health policy and management at Harvard T. H. Chan School of Public Health, Boston, said the review is "very thorough and documents a really wide literature that is difficult to summarize, which is an impressive contribution."
Barnett, who's familiar with the review findings but didn't take part in the research, also noted that the review doesn't confirm whether the perceived obstacles actually exist or how they can be fixed. In addition, he said, "the authors spend very little time addressing the elephant in the room, which is that addiction care is poorly compensated. If physicians made 10 times the money for addiction care, I bet a lot of this 'reluctance' would disappear."
Additionally, he said, "it's easy to endorse innocuous excuses for reluctance when the real reason is that a physician just doesn't want to treat a stigmatized population."
The study was funded by the National Institute on Drug Abuse. Two authors disclosed receiving support from the Intramural Research Program, National Institute on Drug Abuse, and National Institutes of Health. Wakeman is an author and a textbook editor for Wolters Kluwer and Springer. Barnett had no disclosures.
