PROMOTING EQUALITY
Implementation of this guidance is the responsibility of local commissioners and/or providers. Commissioners and providers are reminded that it is their responsibility to implement the guidance, in their local context, in light of their duties to avoid unlawful discrimination and to have regard to promoting equality of opportunity. Nothing in this guidance should be interpreted in a way which would be inconsistent with compliance with those duties.
Workshop on putting NICE guidance into practice
June 2010
NICE public health guidance 24

41. Background Alcohol is attributable for:
14,982 deaths in England (2005)
500,000 recorded crimes (England)
up to 35% of attendances at hospital emergency departments (2003)
24% of adults drink a hazardous or harmful amount
NOTES FOR PRESENTERS:
Key points to raise:
Alcohol-related harm is estimated to cost society between £17.7 billion and £25.1 billion per year (DH 2008).
Between 1980 and 2008 alcohol became 75% more affordable (Information Centre 2009).
It costs the NHS in England up to £2.7 billion a year to treat the chronic and acute effects of drinking (DH 2008).
Additional information:
This is one of three pieces of NICE guidance addressing alcohol-related problems among people aged 10 years and older. The others are:
‘Alcohol-use disorders in adults and young people: clinical management’ (publication expected May 2010).
‘Alcohol dependence and harmful use: diagnosis and management in young people and adults’ (publication expected January 2011).

42. AUDIT – C For people aged 16 years and over
Screening
AUDIT – C For people aged 16 years and over
NOTES FOR PRESENTERS:
Key points to raise:
For the purposes of this guidance, screening involves identifying people who are not seeking treatment for alcohol problems but who may have an alcohol-use disorder. Practitioners may use any contact with clients to carry out this type of screening. The term is not used here to refer to national screening programmes such as those recommended by the UK National Screening Committee (UK NSC). 
In most cases, AUDIT (alcohol use disorders identification test) should be used to assess those aged 16 and older.
If time is limited, an abbreviated version should be used (such as AUDIT-C, AUDIT-PC, CRAFFT, SASQ or FAST).
Screening tools should be appropriate to the setting. For instance, in an emergency department, FAST or PAT would be most appropriate.
For assessing the needs of children and young people aged years see Recommendation 6.
Additional information:
AUDIT is a 10 question screening tool that asks about drinking frequency and intensity. It can detect 92% of hazardous and harmful drinkers.
Categories of risk can be defined by scores used in the AUDIT, these are:
1-7: low risk drinking
8-15: hazardous drinking
16-19: harmful drinking
20+: possible dependence
Shorter versions of the AUDIT tool range between one and four questions (such as AUDIT-C on the slide above). Although these are useful in settings with limited time available, they are generally less accurate than the full AUDIT and do not differentiate clearly between hazardous, harmful and possibly dependent drinking.
Scoring: A total of 5+ indicates increasing or higher risk drinking.

43. Summary Addresses recognising alcohol dependency
Advice on “brief intervention”
Criteria for specialist referral
show signs of moderate or severe alcohol-dependence
have failed to benefit from structured brief advice and an extended brief intervention and still want help
show signs of severe alcohol-related impairment or have a related co-morbid condition

45. Acute alcohol withdrawal: 1
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.
NOTES FOR PRESENTERS:
Key priority for implementation recommendation in full: shown on slide
Other recommendations:
For young people under 16 years who are in acute alcohol withdrawal, offer admission to hospital for physical and psychosocial assessment, in addition to medically assisted alcohol withdrawal. [ ]
For certain vulnerable people who are in acute alcohol withdrawal (for example, those who are frail, have cognitive impairment or multiple comorbidities, lack social support, have learning difficulties or are 16 or 17 years), consider a lower threshold for admission to hospital for medically assisted alcohol withdrawal.[ ]
For people who are alcohol dependent but not admitted to hospital, offer advice to avoid a sudden reduction in alcohol intake (see additional information) and information about how to contact local alcohol support services. [ ]
Additional information
While abstinence is the goal, a sudden reduction in alcohol intake can result in severe withdrawal in dependent drinkers.

Epidemiology
Weekly alcohol consumption of more than 50 units (men) or more than 35 units (women) by age (years) and gender – Great Britain, 2009
NOTES FOR PRESENTERS:
Key points to raise:
24% of the adult population in England, including 33% of men and 16% of women, consumes alcohol in a way that is potentially or actually harmful to their health or well being (Defined as scoring 8 or more on the Alcohol Use Disorders Identification Test AUDIT) (McManus et al. 2009).
4% of adults in England are alcohol dependent (6% men; 2% women) (Defined as scoring 16 or more on the AUDIT) (Drummond et al. 2005).
Alcohol related hospital admissions increased by 85% between 2002–03 and 2008–09, accounting for 945,000 admissions with a primary or secondary diagnosis wholly or partly related to alcohol in 2006–07, 7% of all hospital admissions (North West Public Health Observatory 2010).
Additional information
To clarify the terms used in association with alcohol consumption and its risks, the Department of Health now recommends the use of terms: lower risk, increasing risk and higher risk because these are more readily understood by the general public and reflect the level of risk incurred by drinkers as their consumption increases. These terms differ from the categories of alcohol dependence identified on the previous slide. Alcohol dependence is a type of drinking that develops in regular excessive drinkers, mainly in those drinking at higher risk levels (Department of Health’s Learning Centre. E-learning for primary care, Available at
For more information about the terms lower risk, increasing risk and higher risk, visit the alcohol learning centre

48. Background
Current practice and service provision across the country is varied
Only 6% per year of people aged 16–65 years who are alcohol dependent receive treatment
Comorbid mental and physical disorders are common.
NOTES FOR PRESENTERS:
Key points to raise:
Comorbid mental disorders commonly include depression, anxiety disorders and drug misuse. Physical comorbidities, which are common, include gastrointestinal disorders and neurological and cardiovascular disease. Many people experience long-term consequences of alcohol misuse that may significantly shorten their life even when alcohol consumption has stopped or reduced.
Of the 1 million people aged between 16 and 65 who are alcohol dependent in England, only about 6% per year receive treatment. Reasons for this include the often long period between developing alcohol dependence and seeking help, limited availability of specialist alcohol treatment services in some parts of England and under-identification of alcohol misuse by health and social care professionals.
Diagnosis and assessment of the severity of alcohol misuse is important because it points to the treatment interventions required. Acute withdrawal from alcohol in the absence of medical management can be hazardous in people with severe alcohol dependence, as it may lead to seizures, delirium tremens and, in some instances, death.
Current practice and service provision across the country is varied and access to a range of assisted withdrawal and treatment services and psychological interventions varies as a consequence. In addition, when the alcohol misuse has been effectively treated, many people continue to experience problems in accessing services for comorbid mental and physical health problems. Alcohol service structures are poorly developed, with care pathways often ill defined.

49. Assisted alcohol withdrawal
Person who drinks > 15 units alcohol per day or scores > 20 on AUDIT
Assessment
Consider offering:
– assessment for and delivery of a community-based assisted withdrawal, or
– assessment and management in specialist alcohol services if there are safety concerns about a community-based assisted withdrawal.
NOTES FOR PRESENTERS:
Key points to raise:
See page 15 of the quick reference guide for more information about outpatient based community withdrawal programmes and intensive community withdrawal programmes.
See slide 16 and see page 16 of the quick reference guide for more information about recommended drug regimes for assisted withdrawal programmes.
See slide 24 for details of the Sample chlordiazepoxide dosing regimens implementation tool which provides examples of fixed-dose and symptom-triggered regimens for chlordiazepoxide dosing in alcohol withdrawal.
The evidence indicated that a community setting for assisted withdrawal is as clinically effective and safe for the majority of patients as an inpatient or residential setting and it is also likely to be more cost effective.
The group of experts who developed this guideline identified that symptom-triggered assisted withdrawal was practical only in those inpatient settings that had 24-hour medical monitoring and high levels of specially trained staff. Therefore, the preferred method for assisted withdrawal was a fixed-dose regimen for community and residential settings.
Community base assisted withdrawal
Inpatient and residential withdrawal
Intensive community programmes after assisted withdrawal for severe or mild to moderate dependence with complex needs
