• Do you drink?
• How does drinking affect you?

Brief Intervention
…is a method of identifying alcohol consumption at a level sufficiently high to cause concern.
Alcohol Screening…

What is Brief Intervention?
• can be anything from a short conversation to a number of sessions
Brief interventions help the patient to understand:
•What consequences likely to be
•What they can do about it
•What help is available

Bien, T. H., Miller, W. R. and Tonigan, J. (1993) Brief interventions for alcohol problems: a review. Addiction 88, 315–336.
Does brief intervention work?
1 in 8
individuals drinking at hazardous or harmful levels act on their doctors advice and
moderate their drinking to low risk levels.
This compares to 1 in 20 individuals offered smoking advice (1 in 10 when nicotine
replacements are offered).
Alcohol: No Ordinary Commodity - Research and Public Policy (Babor et al 2003)
Does more intervention help more?
Brief Intervention:• is often as effective as more extensive
treatments• should not substitute for specialist treatment• Might serve as an initial treatment for
severely dependent

Calculating units of alcohol
Litres x ABV = Units
Examples: 1 Litre of 4% lager = 4 units

Question time
Learning trios
• In groups of 3 you will take turns to be the GP/practitioner, patient and observer in role play – each person will have a go at being all three
• The patient and the GP will each play the character identified in the case given to them on the card
• The GP will deliver the AUDIT and undertake alcohol unit calculation
• The GP’s role is to respond and deliver a “brief intervention” to the patient if appropriate
• The Observer’s role is to note what helps and hinders the interactions between GP and Patient and then feedback to the GP and Patient in the five remaining minutes before swapping roles
• The exercise is completed when all members have had an opportunity to play GP, patient and observer
Brief intervention exercise
• Include an AUDIT assessment• Decide what level of intervention is
appropriate for your case• Conduct a brief intervention if appropriate

Risks
Case Scenario
A 36 year old man attends your surgery on a Friday afternoon. Mildly intoxicated.
PC: He says that he is dependent on alcohol and will go into withdrawal soon as he ran out of money to buy alcohol. He requests an alcohol detoxification.
O/E: Overall well, no signs of malnourishment.
No signs of alcohol withdrawal
Case Scenario
A 46 year old woman attends your surgery.
PC Feeling unwell in the morning, vomiting at times
increasing memory problems
O/E Looks malnourished, without any specific findings. BP 155/90, pulse 90. Liver slightly enlarged.
As you have no idea what is going on, you request a blood test: FBC, U&E, LFTs, TFTs. All come back as normal apart from the LFTs, which are slightly raised (<2x normal).
Case scenario
A 25 year old man attends your surgery. He is drunk to a degree that he could not find your consultation room initially.
He requests a sick note as he is an alcoholic.
Investigations
Dependency makes physical harm caused by alcohol more likely
but
a substantial amount of harmful drinking patients will develop medical problems
Like in coronary heart disease, a low risk score does not guarantee safety.
Investigations
• Simple questionnaire-based screening tools are more effective to identify problematic drinking
• FBC (anaemia and raised MCV)
• LFT (consider GGT)
Abnormal blood tests – what now?
NICE recommends:
• Abnormal LFTs – exclude alternative causes of liver disease
• Refer to a specialist to confirm a clinical diagnosis of alcohol-related liver disease.
National Institute of Clinical Excellence: CG100 Alcohol-use disorders: physical complications. Published May 2010
GGT
• only elevated in 30% heavy drinkers • up to 50% of all raised GGT is due for other
reasons• less likely to be elevated in young people,
episodic drinkers, women• A possible tool in monitoring
Physical signs of alcohol misuse
• Peripheral neuropathy
• Signs of chronic liver disease
• Neurological symptoms
• Proximal myopathy
• Cardiomyopathy
• Enteropathy
• Signs of withdrawal
Why assess dependence?
… because it is dangerous not to!
• Sudden stop of drinking may result in developing serious and life threatening conditions such as withdrawal fits, delirium tremens and Wernicke’s encephalopathy.
• Non-dependent drinkers can usually cut down and reduce associated problems
• Dependent drinkers (by definition) find reducing more difficult.
• Dependent drinkers generally need assistance to stop drinking
Dependent vs harmful drinkers
• AUDIT > 16 requires further assessment• AUDIT score of >35 or >50U per day makes
dependence likely• Need for medically assisted withdrawal and
assessment of co-morbidity • SADQ

Who needs detoxification? Use SADQ!
A sobering thought…..
• Detoxification is but one event in a continuing process
• It is a technical step between preparation and aftercare
• As a stand alone treatment can do more harm than good
• Detoxification from opiates and alcohol are two very different events
• Detoxification from opiates is uncomfortable, but fairly safe, whilst detoxification from alcohol is potentially dangerous, and can be permanently disabling or fatal
Who doesn’t need detoxification?
• Generally <15 units/day (M) or 10 units/day (F)• No recent withdrawal symptoms• No drinking to prevent withdrawal• Occasional binges lasting <1 week• SADQ (Severity of Alcohol Dependence
Questionnaire) < 4
Where can detoxifications take place?
• General Hospital• Psychiatric Hospital• Non statutory rehab or detoxification unit• Community
Community detoxification shows similar outcomes to inpatient – 75% successful in community
Community setting preferred by most patients Accessibility and trust in practitioner is key advantage Cost advantage

Alcohol Withdrawal Syndrome (AWS)
• Autonomic over-activity and hyperactivity• Anxiety and tremor• Nausea and vomiting• Sweating• Tachycardia• Hypertension• Pyrexia
Progression of AWS
Complications of AWS
• Withdrawal seizures
• Delirium Tremens
• Wernicke’s encephalopathy and alcohol confusional withdrawal syndromes
• Severe depression/suicide
• Cardiovascular catastrophe (CVA, MI)
Beware the older patient…
NICE guidelines on Detoxification
Acute alcohol withdrawal
For people in acute alcohol withdrawal with, or who are assessed to be at high risk of developing, alcohol withdrawal seizures or delirium tremens, offer admission to hospital for medically assisted alcohol withdrawal.
National Institute of Clinical Excellence: CG100 Alcohol-use disorders: physical complications (CG100). Published May 2010
Medication
Harm reduction
Thiamine, Vit B Costrong
Detoxification
Chlordiazepoxide, Diazepam, Carbamazepine
Relapse prevention or controlled reduction
Naltrexone Nalmefene
Disulfiram (Antabuse®) Acamprosate
Thiamine
Offer prophylactic oral thiamine to harmful or dependent drinkers:
• if they are malnourished or at risk of malnourishment or
• if they have decompensated liver disease or
• if they are in acute withdrawal or
• before and during a planned medically assisted alcohol withdrawal.

flushing, palpitations, hypotension, vomiting, headache
• Should be initiated in consultation with specialist service
