Alcohol Use Disorder: From Screening to Treatment—What Every PA Should Know

PA Mindset Matters | Mini Mindset

Alcohol is everywhere. From celebrations and social gatherings to unwinding after a long day, drinking is deeply embedded in our culture. But when does alcohol use become a clinical concern, and how can healthcare providers recognize when a patient needs help?

Alcohol use disorder (AUD) is one of the most prevalent substance use disorders worldwide, contributing to significant medical, psychiatric, and social consequences. Yet it frequently goes unrecognized in clinical practice.

In this Mini Mindset episode of PA Mindset Matters, we explore the essentials of identifying, assessing, and treating AUD, with practical insights that PAs can apply across specialties.

Understanding Alcohol Use Disorder

AUD is not simply a matter of drinking too much or lacking willpower. It is a complex condition influenced by genetics, environment, personality traits, and cognitive functioning.

Genetics may account for approximately half of an individual's vulnerability to AUD. Environmental influences, including family dynamics, early exposure, and peer relationships, also contribute. Co-occurring psychiatric conditions, particularly depression, bipolar disorder, and other substance use disorders, can further complicate the clinical picture.

Clinical Pearl: AUD is a medical condition, not a moral failing. Approaching patients with curiosity rather than judgment creates opportunities for meaningful conversations about alcohol use.

Screening: Starting the Conversation

One of the most valuable tools PAs have is the ability to identify unhealthy alcohol use before serious complications develop.

Several validated screening instruments can help:

• AUDIT/AUDIT-C: Identifies unhealthy alcohol consumption and potential AUD.

• CAGE: Four brief questions exploring attempts to cut down, criticism, guilt, and morning drinking.

• SASQ: A single-question approach to identifying unhealthy alcohol use.

• T-ACE: A screening tool developed for identifying risky drinking during pregnancy.

Screening is only the beginning. A positive result should lead to further assessment, a nonjudgmental conversation, and an individualized plan.

Clinical Pearl: Asking about alcohol use should be as routine as asking about tobacco use, medications, or sleep.

Recognizing Intoxication and Withdrawal

Alcohol intoxication can present with slurred speech, impaired coordination, unsteady gait, poor judgment, and changes in attention or memory. Severe intoxication can progress to respiratory depression, stupor, or coma.

Withdrawal presents a different challenge and can become life-threatening.

Symptoms may begin within hours after a significant reduction or cessation of prolonged heavy alcohol use. Early symptoms include tremors, anxiety, nausea, sweating, and insomnia. More severe withdrawal can involve hallucinations, seizures, and delirium tremens.

Withdrawal severity depends on multiple factors, including prior withdrawal history, drinking patterns, and co-occurring medical conditions.

Clinical Pearl: A history of withdrawal seizures or delirium tremens is an important warning sign. Patients at risk for complicated withdrawal require prompt assessment and an appropriate level of medical monitoring.

Complications Beyond the Liver

Although liver disease is often associated with chronic alcohol use, AUD affects nearly every organ system.

Neurologic complications include peripheral neuropathy, cerebellar dysfunction, and thiamine-deficiency syndromes.

Two particularly important conditions are:

Wernicke Encephalopathy: An acute neurologic emergency associated with thiamine deficiency. Classic findings include confusion, ataxia, and ocular abnormalities, although not every patient presents with all three.

Korsakoff Syndrome: A chronic amnestic disorder characterized by profound memory impairment and, sometimes, confabulation.

Chronic alcohol use also contributes to cardiovascular disease, pancreatitis, gastrointestinal complications, malnutrition, and reproductive health concerns.

Alcohol exposure during pregnancy can result in fetal alcohol spectrum disorders (FASD), affecting growth, neurodevelopment, and lifelong functioning. No safe level of alcohol consumption during pregnancy has been established.

Clinical Pearl: Think beyond intoxication. A patient presenting with confusion, gait abnormalities, or unexplained cognitive changes may have an alcohol-related neurologic complication.

Managing Withdrawal: CIWA-Ar and Thiamine

For patients experiencing alcohol withdrawal, structured assessment helps guide management.

The Clinical Institute Withdrawal Assessment for Alcohol, Revised (CIWA-Ar) evaluates symptoms including tremors, sweating, agitation, nausea, anxiety, sensory disturbances, and orientation.

When appropriate, CIWA-Ar can support symptom-triggered treatment protocols, often involving benzodiazepines. However, it should complement clinical judgment rather than replace assessment of withdrawal risk, medical stability, and monitoring needs.

Thiamine supplementation is another essential consideration, particularly for patients with chronic heavy alcohol use, malnutrition, or suspected Wernicke encephalopathy. In patients at risk, thiamine should be administered promptly, ideally before glucose when feasible, without delaying emergency treatment of hypoglycemia.

Clinical Pearl: Withdrawal management is about more than controlling symptoms. Preventing seizures, delirium, and neurologic injury is equally important.

SBIRT: A Practical Framework for Every PA

Not every patient with unhealthy alcohol use needs inpatient treatment, but every patient deserves an opportunity for intervention.

SBIRT provides a practical approach:

• Screening: Identify unhealthy alcohol use using validated tools.

• Brief Intervention: Engage patients in a motivational, nonjudgmental conversation about their drinking and readiness for change.

• Referral to Treatment: Connect patients with medication, counseling, and additional recovery resources when indicated.

Even a brief conversation can help patients recognize risks and consider change.

Medications for Alcohol Use Disorder

AUD treatment extends well beyond detoxification. Long-term management may include medications, psychotherapy, behavioral interventions, and recovery support.

Three FDA-approved medications are commonly considered:

Naltrexone: Reduces the rewarding effects of alcohol and can help decrease heavy drinking. Available in oral and monthly injectable formulations, it requires careful consideration of opioid use and liver function.

Acamprosate: Helps support abstinence after alcohol cessation and is particularly useful for patients working toward sustained recovery. Renal function is an important prescribing consideration.

Disulfiram: Produces an unpleasant physical reaction when alcohol is consumed and may be appropriate for carefully selected, motivated patients.

Other medications, including topiramate and emerging treatments such as GLP-1 receptor agonists, are being explored for their potential roles in AUD treatment. These approaches differ in the strength of available evidence and are not FDA-approved for AUD.

Clinical Pearl: Treatment should begin with the patient's goals. Reducing heavy drinking, achieving abstinence, and maintaining recovery may require different strategies, but all benefit from ongoing, patient-centered care.

The Takeaway: Every PA Has a Role

Alcohol use disorder is not confined to addiction medicine or psychiatry. Patients experiencing AUD present in primary care, emergency departments, surgical services, women's health, and nearly every other clinical setting.

Recognizing unhealthy alcohol use, identifying dangerous withdrawal, understanding treatment options, and approaching patients without stigma are skills every PA should develop.

We don't have to solve every aspect of a patient's alcohol use in one encounter. Sometimes the most meaningful intervention begins with a simple question, a compassionate response, and a willingness to keep the conversation going.
