About a quarter of the UK population drink alcohol at a level that is harmful and over 4% are dependent. Alcohol use disorders are also increasing in children and young people. This new guideline reviews the evidence for the diagnosis and assessment of alcohol use disorders, organisation and delivery of care, assisted alcohol withdrawal, and psychological and pharmacological interventions, and includes a chapter on experience of care. RCPsych Publications is the publishing arm of the Royal College of Psychiatrists (based in London, United Kingdom), which has been promoting excellence in mental health care since 1841. Produced by the same editorial team who publish The British Journal of Psychiatry, they sell books for both psychiatrists and other mental health professionals; and also many written for the general public. Their popular series include the College Seminars Series, the NICE mental health guidelines and the Books Beyond Words series for people with intellectual disabilities.
