Tens of thousands of hospital admissions for alcohol could be prevented each year if services to help drinkers were improved, a report said.
Hospital admissions could be cut by 5% while health costs would drop by £1.6 million in each district hospital across the UK, it said.
Overall, the UK economy could save £393 million if services were made more effective.
The joint study, by the British Society of Gastroenterology, Alcohol Health Alliance UK and the British Association for Study of the Liver, calls for closer working between GP surgeries and hospitals.
It said hospital departments - including A&E and mental health - should link up to provide quick help to people with alcohol problems. A specialist nurse service running seven days a week could help support the departments, it said.
Advice sessions lasting 20 to 40 minutes would give people feedback on the health risks from drinking as well as ways to cut alcohol intake.
Meanwhile, an assertive outreach alcohol service (AOAS) could be set up in each health district to treat people who frequently end up in hospital because of drinking.
This would free up hospital time and resources and enable those with drink problems to be treated in a supportive community environment, the report said.
Hospital admissions for alcohol were almost one million in 2008-09, figures released by the Liberal Democrats in December showed. Around 40,000 deaths a year are linked to alcohol misuse, at a cost to the NHS of £2.7 billion.
The report said: "Specialist alcohol care can pull people back from the brink of the most devastating consequences of alcohol misuse, especially alcohol-related liver disease, give them back their self-respect and restore them to their families and communities."
