Alcohol Use Screening & Brief Intervention: A Guide for PCPs

Alcohol is one of those topics that can make an exam room feel a little smaller. You’re already behind. The patient is here for hypertension, sleep, reflux, and labs. Then the intake form quietly says: 4 drinks, 4+ times per week. The blood pressure is a little elevated. The patient mentions, “I’ve been drinking more than I probably should.”

And there it is: the invitation. Not to diagnose everyone with alcohol use disorder. Not to deliver a seminar on the harms of alcohol. Just to ask, listen, and offer one small next step. That is the heart of alcohol screening and brief intervention in primary care.

Why This Matters

Alcohol use is common, and unhealthy alcohol use is often hiding in plain sight. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) notes that excessive alcohol use contributed to about 178,000 deaths per year in the United States during 2020–2021. Alcohol also contributes to injuries, hypertension, liver disease, cancers, depression, sleep disruption, relationship stress, and medication interactions — the kinds of things PCPs see every day.

The US Preventive Services Task Force (USPSTF) recommends screening all adults 18 and older, including pregnant patients, for unhealthy alcohol use and providing brief behavioral counseling interventions for those with risky or hazardous alcohol use. The good news? This does not need to be complicated.

Start With a Tool That Fits Your Workflow

Two practical screening options that work well in primary care are the single alcohol screening question (my favorite) and the AUDIT-C.

The single-question screen is beautifully simple: “How many times in the past year have you had 5 or more drinks in a day for men, or 4 or more drinks in a day for women and adults over 65?” Any answer greater than zero is considered positive.

The AUDIT-C is a three-question tool that asks about frequency, typical quantity, and heavy use episodes. A score of 4 or more for men or 3 or more for women is generally considered positive. The AUDIT-C is quick, validated, and easy to embed in rooming, annual wellness visits, pre-visit questionnaires, or the EHR.

And yes, it helps to define a “drink,” so we are all on the same page. One standard drink is 14 grams of ethanol: 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80-proof spirits. Translation: the “standard pour” may be a 10+ oz glass of wine.

What Counts as Risky Alcohol Use?

NIAAA defines higher-risk drinking as more than 4 drinks in a day or more than 14 drinks per week for men, and more than 3 drinks in a day or more than 7 drinks per week for women and adults 65 and older. (5)

But numbers are only part of the story. The most clinically useful question may be: “Is alcohol causing any problems?” Missed work, arguments, reflux, poor sleep, falls, worsening anxiety, unsafe driving, abnormal labs, or using alcohol despite wanting to cut back all matter.

The Brief Intervention: Small and Doable

A brief intervention does not require magic. Think FLO:

Feedback: “Your screening score suggests your use may be putting your health at risk.”

Listen: “What do you make of that?”

Options: “Would you be open to talking about ways to cut back, take a break, or get more support?”

That’s it. No shame. No scolding. No “Well, actually…” Just a respectful conversation that treats the patient like the expert on their own life (which they are). Sometimes the patient nods and says, “Yeah, I’ve been meaning to cut back.” Other times, they pause like no one has asked them this question out loud before.

Motivational interviewing helps here too. Ask permission. Reflect what you hear. Find the patient’s own reasons for change. “On a scale of 0 to 10, how ready are you to make a change?” is useful, but the follow-up is where the gold lives: “Why that number and not lower?”

When Screening Becomes Diagnosis

If the screen is positive, consider an assessment tool. The 10-item AUDIT can help clarify severity. Then think through the DSM-5 criteria for alcohol use disorder: use causing significant impairment or distress, with symptoms such as alcohol use more than intended, unsuccessful attempts to cut down, cravings, role impairment, hazardous use, tolerance, or withdrawal. Mild AUD is 2–3 criteria, moderate is 4–5, and severe is 6 or more.

Also ask about withdrawal. This is the “do not miss” part. Morning shakes, sweats, tachycardia, anxiety, insomnia, seizures, or prior delirium tremens should change your plan. Patients often keep using alcohol to avoid withdrawal in order to maintain employment and family obligations.

Treatment and Referral Pathways

For risky alcohol use without AUD, brief counseling and follow-up may be enough. For mild AUD, brief intervention, mutual support, therapy, and close follow-up may work well. For moderate to severe AUD, pair behavioral support with medication when it makes sense.

FDA-approved medication options include naltrexone, acamprosate, disulfiram, and extended-release injectable naltrexone. (6) Naltrexone can be started while a patient is using alcohol, but avoid it in patients using opioids or with significant hepatic failure. Acamprosate can be helpful for maintaining abstinence and is often a good option when opioid use is present, but it requires renal dosing consideration. Antabuse is considered a 2^nd line option, and I’ve reached for this only once in a 10+ year career.

Referral is appropriate when there is complicated withdrawal risk, severe AUD, pregnancy with ongoing alcohol use, significant psychiatric comorbidity, repeated unsuccessful outpatient attempts, unstable housing, safety concerns, or patient preference for higher support. Know your local pathways: behavioral health, addiction medicine, intensive outpatient programs, inpatient detox, mutual help groups, and the NIAAA Alcohol Treatment Navigator.

Make It a Team Sport

Alcohol screening works best when it is not dependent on one clinician remembering one more thing. Let the team support you. Front desk or pre-visit forms can administer the AUDIT-C. MAs can score and document it. Clinicians can review, normalize, and counsel. Behavioral health can help build a change plan. Follow-up can be scheduled before the patient leaves.

Alcohol screening is not about catching patients doing something wrong. It is about noticing risk early, naming it kindly, and offering help before things get worse. A good brief intervention may sound like this:

“Lots of people have found their alcohol use creeping up, especially with stress. Your score suggests alcohol may be affecting your health. Would it be okay if we talked for a minute about this?” That minute matters. Because sometimes, that small invitation is the first step toward behavior change.
