Doctors across the United States are rethinking how addiction treatment in primary care reaches people who need it most, and new research from the University of Cincinnati suggests this shift matters more than ever.

According to the 2024 National Survey on Drug Use and Health, approximately 48.4 million Americans aged 12 and older live with a substance use disorder. That figure represents about 16.8 per cent of the population. Yet fewer than one in four of those individuals ever receives any form of treatment. The problem is not purely about funding or policy. Training gaps and slow detection play a significant role.

The earlier a doctor spots a substance use disorder and acts on it, the better the chance of a full recovery. Getting more clinicians prepared to intervene at the primary care level is, therefore, not just useful. It is urgent.

A New Model for Addiction Treatment in Primary Care

Researchers published findings in the journal Academic Medicine showing that embedding substance use disorder treatment within primary care training clinics can widen patient access and lift physician confidence at the same time.

The University of Cincinnati team launched the project in 2023 inside a resident primary care practice. Attending physicians, clinical pharmacists, addiction medicine fellows, and internal medicine residents joined forces to deliver structured care during routine outpatient appointments.

In the programme’s first 15 weeks, the clinic recorded 73 patient visits. Opioid use disorder and alcohol use disorder featured most often among the diagnoses.

Physician Confidence Rises Sharply

The research team surveyed 18 residents before and after their rotation. Eleven responded, and their results told a clear story. Confidence improved across diagnosing substance use disorders, interpreting urine drug tests, and starting appropriate treatment plans for patients who needed structured support to stop using substances.

Lead author Dr Michael Binder, an adjunct associate professor of medicine and University of Cincinnati Health physician, pointed out that addiction care has long been taught theoretically rather than practically.

“We wanted to create a model where treating substance use disorders is integrated into everyday primary care, because that is where many patients already are,” he said.

Many residents managed opioid use disorder cases and guided patients through the early stages of recovery for the first time. Within weeks, their confidence to do both independently grew substantially. That confidence leads to earlier intervention, and earlier intervention is where real differences get made.

Substance Use Disorder Treatment Needs to Happen Earlier

Timing is one of the strongest arguments for building addiction treatment in primary care. Patients see their GP or general physician long before they ever approach a specialist addiction service. Trained clinicians working at this level can catch problems earlier, before dependence takes firmer hold and recovery becomes significantly harder.

A doctor who spots the warning signs of a developing substance use disorder, talks honestly with the patient, and connects them with support straight away delivers far more value than a referral system with weeks of waiting time built in.

“Integrating addiction treatment into primary care helps normalise it,” Dr Binder said. “Patients can receive care for substance use disorders in the same place they manage diabetes or hypertension, which can lower barriers and improve engagement.”

Fewer barriers mean more people get help sooner. Getting help sooner produces better outcomes and a stronger chance of lasting recovery.

Voices From the Clinic

Ellen Jochum, chief physician resident at the clinic, said her training before this programme reflected what most medical education offers. Addiction medicine appeared in her coursework, but only in the context of inpatient care, far from the everyday outpatient setting where most patients first turn up.

“In medical school, we learned about the medications used for opioid use disorder and alcohol use disorder and how to treat alcohol withdrawal, but this was in the context of inpatient care, not outpatient,” she explained.

Her rotation changed that picture entirely. Managing substance use disorder treatment alongside recovery-focused patient conversations and community referrals gave her a clinical readiness that no classroom had delivered.

“I feel much more prepared and now feel comfortable starting treatment for patients with a substance use disorder, knowing the resources available to them,” she said. “I am going to be starting as a primary care physician this summer, and I am so grateful I have this training to carry into my future practice.”

What Comes Next for Addiction Treatment in Primary Care

Researchers describe this as an early evaluation. Future studies will track long-term patient outcomes and explore how addiction training shapes physician behaviour long after residency ends.

The team wants other academic medical centres to consider adapting this model. Access to evidence-based substance use disorder treatment remains too limited. The case for broader adoption is difficult to dispute.

“Ultimately, we need more clinicians who feel prepared to treat substance use disorders,” Dr Binder said. “Embedding this care into primary care training is one way to help make that happen.”

Substance use disorders do not begin in specialist clinics and recovery should not have to wait for one. When doctors at every level of healthcare feel trained, confident, and ready to act early, fewer people ever reach crisis point. Prevention and treatment share the same goal, and that is exactly where lives get saved.
