Alcohol Misuse

By Mahya Mirfattahi

HDR LRCH

Wednesday 17th March

Learning Outcomes• RCGP Curriculum Statement 15.3: Drug and Alcohol

Problems• Manifestation of alcohol problems• Health and social burden of excess alcohol consumption• The use of screening tools for alcohol such as Cut down Annoyed Guilty

Eye-opener (CAGE) and Alcohol Use Disorders Identification Test (AUDIT)

• The range of treatment interventions available including pharmacological interventions

• The impact that health professionals can make by providing brief intervention for excess alcohol use

• Alcohol-related emergencies• Adopt a person-centred approach, whilst acknowledging the conflicts

between a perceived self-inflicted problem & a right to evidence-based treatment

DOH Definitions

• Recommends use of terms• Lower risk

– Implies that no level of alcohol consumption is completely safe e.g. drinking & driving

• Increasing risk– Regularly drinking >2-3 units/day women, >3-4

units/day men

• Higher risk– Regularly drinking >6 units/day or 35 units/week

women, >8 units/day or >50 units/week men

Definitions

• Hazardous drinking– Regular consumption above recommended daily

intake– Men >5 units, women >3 units– Pattern of drinking carries the risk of harm, but

have not yet experienced alcohol related problem

• Harmful drinking– ICD-10 defines as pattern of drinking that causes

damage to physical or mental health

38 yr old, male• Presents to you with symptoms of GORD• You explore his lifestyle• He drinks 4 pints/night most days of week, on

Saturday nights he goes out with the lads & cannot tell you how much he has

• Some mornings he notices a tremor & has sweats

• He tells you he has difficulty in sleeping• He is also having relationship problems• He has called in sick at work on a few occasions

Alcohol Dependence• Cluster of psychological,

behavioural and cognitive symptoms

• 3 or more of the following experienced together in last 12 months

• Relatively small group compared to lower, increasing or higher risk drinkers = 3% population

Alcohol Dependence ICD-10• Compulsion – strong desire or sense of compulsion to take

alcohol• Loss of control – difficulties in controlling drinking in terms of

onset, termination or levels of use• Withdrawal – physiological state in response to cessation or

reduction of use, or drinking to relieve or avoid withdrawal symptoms

• Tolerance – increased doses required to achieve effects originally produced by lower doses

• Pre-occupation with alcohol – progressive neglect of alternative pleasures or interests, or increased amount of time to obtain or take alcohol, or recover from its effects

• Persistent use – continued use despite evidence of harmful consequences

World’s first wine• Ancient Persian fable• A princess having lost favour with the King

attempts to poison herself by eating a jar of “spoiled” grapes. She became intoxicated & giddy & fell asleep. When she woke up she found the stressors that made her life so intolerable dispersed. Her subsequent conduct changed so remarkably that she regained the King’s favour. He shared his daughter’s discovery with his court & decreed an increase production of “spoiled” grapes

The evidence…

• Jar one of six vessels found at Neolithic village site in Iran

• Remains of a 7,000 year old wine• Chemical tests show evidence of

grape & resin from a tree used as a preservative showing that wine was deliberately made & not just unintentional fermentation of grapes

Identification & Brief Advice

• IBA pathway– Initial Screening to identify whether an

individual is drinking above lower risk levels

– Full Identification to define level of risk– Brief Advice & Referral if necessary

Screening Tools

• CAGE• Have you ever felt you should Cut down on your

drinking?• Have people Annoyed you by criticizing your

drinking?• Have you ever felt bad or Guilty about your drinking?• Have you ever had a drink first thing in the morning to

steady your nerves of get rid of a hangover? (Eye-opener)

AUDIT

• High sensitivity 92% & specificity 94%

• 10 questions

• Detects all types of alcohol misuse

• Scores >20 possible dependence

• Too time consuming, therefore shorter versions used as pre-screen have similar validity & reliability

AUDIT-C

• 3 questions from AUDIT

• Short

• Indicates whether an individual is potentially drinking at increasing or higher risk levels

• Does not detect alcohol dependence

AUDIT-PC

• For use in primary care

• 5 questions

• Identifies increasing or higher risk levels

Brief Advice

• Is the patient willing to change?

• Use Readiness Ruler

• On a scale of 1-10 “How important is it for you to change your drinking?”

• Useful framework is stages of change model

Elements of Brief Interventions

• For hazardous or harmful drinker willing to change• Feedback – present screening results• Responsibility – emphasis on personal responsibility

for change• Advice – to cut down or abstain• Menu – options for changing drinking pattern, jointly

with patient establishing goal(s)• Empathic interviewing – active listening, without

confrontation, exploring with patients reasons for change

• Self efficacy – encouragement

In practise…• Some statement to prepare the patient for

intervention• Give patient leaflet• List common effects of drinking• Give feedback on other people• Provide information – point out benefits of cutting

down• Establish a goal• Explain units & give advice on limits• Provide encouragement

Detoxification• Alcohol dependence• Increasing or higher risk drinker who has not

responded to previous brief intervention• If the drinker wants to stop drinking refer to

community alcohol team for support & treatment• Involve family & friends• Give general advice• Drinkers should set a ‘stop drinking’ date• Stress that medication does not stop urge but

reduces withdrawal symptoms

Community Detoxification• Usually uses a reducing regimen of

chlordiazepoxide over a week long period• Referral to CAT

– For Derbyshire county this is 01773 829966– For Derby City: Bradshaw Clinic, 1 Charnwood St, Derby

01332 221700– Addaction

• Frequent follow-up by CAT worker• Ensure patient is taking thiamine supplements

200mg daily for at least duration of detoxification

54 yr old, male

• You have arranged follow-up as he is undergoing community detoxification

• As he walks into the consultation room you notice he is unsteady

• On questioning he appears confused• He cannot remember the events the

previous day• What are you worried about?

Wernicke-Korsakov Syndrome

• Any sign of Wernicke-Korsakov’s patients should receive Pabrinex in a setting with appropriate resuscitation facilities

• Signs: confusion, ataxia (truncal), ophthalmoplegia, nystagmus, memory disturbance, hypothermia, hypotension, coma

• Should continue over several days ideally in an inpatient setting

• In the community patients at risk of Wernicke-Korsakov’s should be given intramuscular Pabrinex

Inpatient Detoxification• Confusion or hallucinations• History of previously complicated withdrawal• Epilepsy or history of fits• Malnourishment• Severe vomiting or diarrhoea• Is at risk of suicide• Has severe dependence coupled with poor co-operation• Failed detoxification at home• Uncontrollable withdrawal symptoms• Acute physical or psychiatric illness• Multiple substance misuse• Poor home environment unsupportive of abstinence

26 yr old, female

• Decides to abstain from alcohol • She normally drinks 3-4 glasses of wine/day• Her flat mate calls the surgery asking for a

home visit as she is worried about her• She feels hot, sweaty, palpitations, doesn’t

know where she is, seems to be drifting in & out of consciousness, claims she can see things that aren’t there like crawling insects

• What are you worried about?

Medications to prevent relapse

• Acamprosate– Enhances GABA transmission & inhibits glutamate– Reduces craving in postwithdrawal period – Should be prescribed for min. 12 months

• Disulfiram (Antabuse)– Deters patients from resuming drinking– Unpleasant reaction – blocks metabolism of

alcohol– Can be dangerous– Minimum of 6 months

Follow-up & support groups

• Patient motivation• Self-help & support groups

– Alcoholics Anonymous www.alcoholics-anonymous.org.uk

– www.al-anon.org.uk– Drink aware www.drinkaware.co.uk– Alcohol concern www.alcoholconcern.org.uk

• Encourage to contact GP if relapse occurs• Patients need to know that if they relapse

there are still support strategies in place

Happy St Patrick’s Day!
