Learning Objectives

You should be able to:

• Screen for alcohol use disorder
• Diagnose alcohol use disorder
• ID multiple peer support options for AUD
• ID multiple medication options for AUD

Cases…

On list for clinic this afternoon:

• 44 yo F smoker c/o insomnia to NAL
• 55 yo F hospital DC for hip fx
• 56 yo M with HTN, DM, GERD, anxiety,

hypertriglyceridemia, chronic pain

• 62 yo M homeless M with ESLD
• 29 yo F new patient here to establish care

Who should be screened for alcohol use?

Comorbidities with Alcohol use

Hypertension GERD Obesity Trauma DM Anemia Liver disease Depression Anxiety PTSD Insomnia **If one of above not controlled on max therapy, or you see 3-4

• n problem list, ask about alcohol!

Screen for Alcohol Use Disorder

• USPSTF recommends universal (category

B)

• “Single” question 82% sensitive, 79%

specific*

– “Do you ever drink alcohol?” – “How many times in the past year have you had ___ or more drinks in a day?”

• 4 for women or men > 65 yo
• 5 for men < 65 yo

Smith PC, et al. J Gen Intern Med. 2009

Some stats

• 87.6% lifetime prevalence of alcohol use

– 56.9% drank in the last month

• ~25% binge in the last month
• 9.2% men, 4.6% women with AUD
• 88,000 die annually in US from alcohol

Diagnosis of Alcohol Use Disorder

1 Had times when you ended up drinking more, or longer, than you intended? 2 More than once wanted to cut down or stop drinking, or tried to, but couldn't? 3 A great deal of time is spent in activities necessary to obtain alcohol, use alcohol, or recover from its effects. (See DSM-IV, criterion 9.) 4 Spent a lot of time drinking? Or being sick or getting over other aftereffects? 5 Found that drinking—or being sick from drinking—often interfered with taking care of your home or family? Or caused job troubles? Or school problems? 6 Continued to drink even though it was causing trouble with your family or friends?

Diagnosis of Alcohol Use Disorder

7 Given up or cut back on activities that were important or interesting to you, or gave you pleasure, in order to drink? 8 More than once gotten into situations while or after drinking that increased your chances of getting hurt (such as driving, swimming, using machinery, walking in a dangerous area, or having unsafe sex)? 9 Continued to drink even though it was making you feel depressed or anxious or adding to another health problem? Or after having had a memory blackout? 10 Had to drink much more than you once did to get the effect you want? Or found that your usual number of drinks had much less effect than before? 11 Found that when the effects of alcohol were wearing off, you had withdrawal symptoms, such as trouble sleeping, shakiness, restlessness, nausea, sweating, a racing heart, or a seizure? Or sensed things that were not there?

The he 4C 4C’s o s of A Add ddict ction

• craving
• loss of control of amount or frequency of

use

• compulsion to use
• use despite consequences

Diagnosis of Alcohol Use Disorder

2-3 symptoms: Mild 4-5 symptoms: Moderate 6+ symptoms: Severe Treatment Decisions Depend on Severity and patient goal

Treatment options depend on severity

• Mild (2-3 criteria)

– Trial of abstinence (TOA)

• Diagnostic and therapeutic
• Moderate (4-5 criteria)

– TOA – Peer support – Pharmacotherapy

• Severe (6+ criteria)

– TOA  medically supervised withdrawal – Peer support – pharmacotherapy

Treatment options depend on patient’s goal

• Abstinence?
• Reduction in # drinks?
• Reduction in # drinking days?
• Reduction in harm to pt from drinking?

Treatment options depend on comorbidities

• Depression/anxiety?
• ESLD?
• Homeless?
• Chronic pain on opioids?
• Other substance use disorder?

The Case: 42 yo M +EtOH screen

42 yo M presents for txfer care HTN, insomnia. +needs 3-4 now to get “buzz” +hangovers led to missed work twice Doesn’t see EtOH as ongoing problem Any “tests” or treatment would you recommend?

42 yo M mild-moderate AUD

Mild-Moderate AUD, new to pt: Brief Intervention

• Educate on alcohol effects

– “Can I tell you a little about how alcohol and sleep?”

• Give the diagnosis

– “You meet criteria for Alcohol Use Disorder”

• TOA

– Patient agrees to 2 week trial of abstinence: 8/10 confidence

• Schedule follow-up

– made it 5 days without (“sleep was a little tough”), then family

• reunion. 4 more nights since, 3 of them 5+ drinks.

42 yo M moderate AUD

• Wants another TOA
• “I’ll do it this time, doc, 10 out of 10”

Other next steps?

PEER SUPPORT GROUPS

Something for everyone

www.aasf.org

Do 12-step groups work?

• Meta-analysis says no*
• Project MATCH: AA as good as CBT if

facilitated to get there**

– 35% 3 y abstinence

*Ferri et al., Cochrane Syst Rev, 2006

42 yo M moderate-severe AUD

• 2 weeks f/u: drank again by day 3.

Increased arguments with GF. “I think I need some more help” What pharmacotherapy might you offer?

PHARMACOTHERAPY FOR AUD

There’s a pill (or a shot) for that

Decrease binges: naltrexone

Pro

• Mu-opioid antagonist

reduces endogenous reward from EtOH

– Pt “learns” not to drink too much

return to heavy drinking:

– MA (n=7793) RR 0.83* – MA (n=2875) NNT 12**

• Safe to take with EtOH

Con

• ?improvement in abstinence

– MA (n=2347): risk reduction 0.05 (0.1 – 0.002)

• SE: transaminitis
• Contraindications: opioids,

LFTs > 5x ULN

Ideal candidate: actively drinking patient not on opioids who wants help to “cut down” Rx: 50 mg po qday or 380 mg IM q4wks

Acute alcohol withdrawal

Benzos > placebo for seizure ppx*

• RR 0.16
• Symptom-triggered > fixed schedule

Phenobarbital = placebo for seizure ppx*

• Carbamazepine > placebo, = benzos for seizure ppx in

mild to moderate + LESS DRINKING AFTER*

• Gabapentin = benzo for seizure ppx in mild to moderate +

less drinking in RCT**

*Amato L, Cochr ane Syst Rev, 2010 **Myrick H, Alcohol Clin Exp Res, 2009

42 yo M mod-severe AUD

• Trial naltrexone – didn’t tolerate (mood and HA)
• Trial gabapentin 300 mg tid – still drinking at 1 mo
• Gabapentin 600 mg tid – 3 drinking episodes @ 1 mo

– SMART recovery

• 100% Abstinent at 1 mo f/u
• 100% Abstinent at 3 mo f/u
• 100% Abstinent at 6 mo f/u -- +GF sign

Take home messages

• Universal screening!
• Diagnose before physically dependent
• AA is not the only game in town
• Medications make it a medical problem
