Drug Detox Services in Primary Care: The Changing Role of General Practice in the USA

Substance use disorder has traditionally been treated separately from mainstream medical care in the United States.

A patient might see a family physician for hypertension, diabetes, respiratory disease or depression, yet be referred to an entirely different treatment system for opioid or alcohol dependence.

That model is changing.

Across the United States, primary care practices, family medicine clinics, community health centres and other ambulatory medical services are playing a greater role in identifying and treating substance use disorders.

This can include screening, assessment, management of selected withdrawal syndromes, medications for substance use disorder, overdose prevention, ongoing medical monitoring and referral to specialised addiction services when required.

The US Substance Abuse and Mental Health Services Administration, or SAMHSA, now specifically encourages the integration of evidence-based substance use disorder services into primary care and other healthcare settings.

This represents an important change in how addiction is approached.

Rather than viewing substance use disorder as something that must always be treated outside general medical practice, it can increasingly be managed as part of a patient’s broader healthcare.

Why integrate addiction treatment into primary care?

Primary care has one major advantage: access.

Patients with substance use disorders may already be attending medical services because of injuries, infections, chronic disease, mental health concerns or other health problems.

This creates an opportunity to identify harmful substance use and offer treatment before further complications occur.

SAMHSA notes that people living with substance use disorders may also be more willing to enter treatment through a primary care setting than through a specialised addiction treatment service.

Primary care can therefore provide an important entry point into treatment.

It also allows substance use disorder to be managed alongside other conditions rather than as an isolated problem.

For example, the same patient may have opioid dependence, chronic pain, hypertension, hepatitis C, anxiety and housing or social difficulties.

Fragmenting these problems between unrelated healthcare services can make treatment considerably harder.

Integrated care allows clinicians to consider the whole patient.

What does “drug detox” actually mean?

The term “drug detox” is widely used by patients searching for help, but clinicians need to use it carefully.

Detoxification generally refers to the management of withdrawal as a person’s body adjusts to stopping or reducing a substance.

The clinical term “withdrawal management” is often more useful because detoxification is not, by itself, treatment for substance use disorder.

This distinction is particularly important with opioids.

For opioid use disorder, the US Centers for Disease Control and Prevention advises that detoxification without medication treatment is not recommended because it is associated with increased risks of returning to opioid use, overdose and overdose death.

The clinical objective should therefore extend beyond simply getting a patient through withdrawal.

Assessment, stabilisation and withdrawal management should ideally provide a pathway into ongoing evidence-based treatment.

What can primary care contribute?

The exact services that can safely be delivered in primary care depend on the substance involved, withdrawal risk, comorbidities, available staff, local regulations and the capability of the individual practice.

However, primary care may potentially contribute to several stages of care.

These include:

• screening for unhealthy alcohol and drug use
• assessing the severity and pattern of substance use
• assessing previous withdrawal complications
• identifying medical and psychiatric comorbidities
• evaluating overdose risk
• assessing whether outpatient treatment is appropriate
• providing or arranging medication treatment
• monitoring treatment response
• providing overdose education and naloxone where appropriate
• coordinating behavioural and psychosocial support
• providing ongoing general medical care
• referring patients requiring a higher level of addiction care.

SAMHSA’s Screening, Brief Intervention, and Referral to Treatment model, commonly known as SBIRT, specifically recognises primary care as an important setting for early identification and intervention.

This means the general medical consultation can become a doorway into treatment rather than simply another missed opportunity.

Not every patient is suitable for outpatient detox

Integration into primary care does not mean every withdrawal syndrome should be managed in a general practice or urgent care clinic.

Clinical triage remains essential.

Withdrawal from some substances can produce serious complications. Alcohol and benzodiazepine withdrawal, for example, can become medically dangerous in some patients.

A clinician considering outpatient withdrawal management needs to assess factors such as the substance being used, dose and duration, previous withdrawal history, history of seizures or delirium, concurrent substance use, physical health, psychiatric risk, pregnancy, social circumstances and the availability of reliable follow-up.

Patients at significant risk may require emergency department assessment, inpatient management or a specialised withdrawal service.

The strength of an integrated model is therefore not that primary care replaces specialist addiction medicine.

It is that primary care becomes part of the addiction treatment system.

Opioid use disorder has changed the primary care model

Opioid use disorder provides perhaps the clearest example of this change.

The three US Food and Drug Administration-approved medications used for opioid use disorder are buprenorphine, methadone and naltrexone.

These medications do not all operate within the same regulatory framework.

Methadone for opioid use disorder remains generally provided through federally certified opioid treatment programs.

Buprenorphine and naltrexone, however, can be incorporated into office-based medical care when clinicians meet the applicable federal and state requirements.

A major regulatory barrier was removed in 2023 when the United States eliminated the federal DATA Waiver, commonly called the X-Waiver, previously required to prescribe buprenorphine for opioid use disorder.

This has made it substantially easier for appropriately authorised clinicians to incorporate opioid use disorder treatment into ordinary healthcare settings.

SAMHSA now actively provides resources specifically for physicians, nurse practitioners and physician assistants who want to integrate medications for opioid use disorder into primary and ambulatory care.

Buprenorphine and Suboxone in general medical practice

Buprenorphine is a partial opioid agonist that can reduce withdrawal symptoms and opioid cravings.

It is commonly prescribed in combination with naloxone, including formulations widely known by the brand name Suboxone.

For suitable patients, office-based buprenorphine treatment can allow opioid use disorder to be managed similarly to other chronic conditions: assessment, initiation of treatment, regular review, medication management and longer-term follow-up.

Importantly, medication treatment should not be confused with short-term detoxification.

Some patients benefit from continuing medication for prolonged periods.

The objective is not necessarily to discontinue medication as quickly as possible. Treatment should instead be individualised according to clinical circumstances, patient goals and evidence-based practice.

Medication treatment for opioid use disorder is associated with reduced overdose risk and lower overall mortality.

A real-world example: urgent care and primary care in Las Vegas

The integration of addiction-related services into general medical settings is already visible in community healthcare.

One example is Sahara West Urgent Care & Wellness in Las Vegas, Nevada, which combines urgent and primary care services with substance use treatment services.

The practice is listed on iSeeGP:

According to the provider’s published information, Sahara West offers outpatient drug and alcohol withdrawal-related care, medication-assisted treatment and Suboxone treatment alongside more conventional urgent and primary care services.

Its broader services include primary care, urgent care, diagnostic imaging, STI testing and other general medical services.

This type of model illustrates an important concept.

A person seeking treatment for substance dependence does not necessarily have to enter the healthcare system through a stand-alone addiction facility.

For appropriately selected patients, assessment and elements of treatment may begin in a familiar community medical environment.

Equally importantly, patients who require more intensive treatment can be identified and referred to an appropriate service.

Detox should be the beginning, not the destination

One of the greatest clinical risks associated with the word “detox” is the implication that removing a drug from the body completes treatment.

It does not.

Substance use disorders are complex conditions influenced by biological, psychological and social factors.

A successful episode of withdrawal management may resolve acute physical dependence without resolving the underlying disorder.

For this reason, good withdrawal management should include planning for what happens next.

Depending on the patient, this may involve medication treatment, counselling, behavioural therapy, peer support, mental healthcare, primary care follow-up, social support or specialised addiction services.

SAMHSA describes medications for opioid use disorder as one component of a broader patient-centred treatment plan.

Primary care is particularly well positioned to provide continuity.

The clinician who assists with the initial problem can potentially remain involved months or years later.

Reducing stigma through ordinary healthcare

There is another potential advantage to integrating substance use treatment into primary care.

It can help normalise treatment.

Patients with diabetes are not expected to attend a separate healthcare system simply because their condition is chronic and behavioural factors may influence it.

Similarly, patients with substance use disorders benefit from evidence-based medical care delivered without judgement.

SAMHSA identifies stigma and unconscious bias as barriers to treatment and encourages healthcare professionals to incorporate non-judgemental substance use disorder care into ordinary practice.

The language clinicians use matters as well.

Terms such as “substance use disorder”, “opioid use disorder” and “person with a substance use disorder” are generally preferable to labels that define an individual by their drug use.

Primary care does not need to do everything

Integration does not require every family physician to operate a comprehensive addiction treatment centre.

A practice can participate at different levels.

One clinic may provide screening, brief intervention and referral.

Another may prescribe buprenorphine and provide ongoing opioid use disorder treatment.

A larger multidisciplinary service may provide medical treatment, behavioural healthcare and recovery support.

What matters is that patients are identified and connected with appropriate evidence-based treatment.

SAMHSA explicitly notes that practices do not have to provide every component themselves. Community partnerships and referral networks can provide counselling, behavioural health services, specialised addiction medicine and other supports.

This is familiar territory for general practice.

Primary care already coordinates cardiologists, psychologists, physiotherapists, endocrinologists, surgeons and community services.

Addiction medicine can be incorporated into the same model.

The future of drug detox services in US primary care

The direction of US healthcare policy is increasingly clear.

Substance use disorder is being treated as a healthcare condition that belongs within mainstream medicine.

Primary care clinicians are being encouraged to screen for substance use disorders, provide evidence-based treatment within their scope and connect patients with specialist services when necessary.

For opioid use disorder in particular, the removal of the X-Waiver has reduced one of the historical barriers to office-based treatment.

The result may be a more accessible continuum of care.

A patient could potentially enter a community medical clinic because they are experiencing withdrawal, receive an assessment, begin appropriate treatment, address other medical problems and remain connected with healthcare throughout recovery.

That is considerably different from viewing detoxification as an isolated event.

Key message for healthcare professionals

Drug detox services incorporated into primary care should not be understood simply as providing medication for a few days while a substance leaves the patient’s body.

The more important development is the integration of substance use disorder care into everyday medicine.

Primary care can identify the problem, assess risk, manage selected patients, initiate or continue evidence-based medications, address coexisting disease and provide continuity.

Specialised addiction services remain essential for patients requiring a higher level of care.

But for many patients, the front door to addiction treatment may increasingly be the same front door they use for the rest of their healthcare.

That represents a significant evolution in American primary care.
