Updating alcohol Cochrane literature review


Updating cochrane systematic reviews makes them most useful and fresh for readers. We updated our review on concurrent alcohol and drug problems again.

Which new studies we found?

We found seven studies that examined 825 people with drug problems. Six of the studies were funded by the National Institutes for Health or by the Health Research Board; one study did not report its funding source.
One study focused on the way people think and act versus an approach based on Alcoholics Anonymous, aiming to motivate the person to develop a desire to stop using drugs or alcohol.

Three studies looked at a counselling style for helping people to explore and resolve doubts about changing their behaviour (group, individual and intensive formats), versus education, or less intensive counselling, or assessment-only.

Two Irish studies and one Swiss You should be homogeneous in the description of the studies; I suggest to not identify these two studies by the country where they were conducted. study looked at practices that aimed to identify an alcohol problem and motivate the person to do something about it versus usual treatment.

Updating Cochrane Review – Key results

The Swiss and Irish studies were directly compared. They took place in general practices (one trial) or methadone clinics (two trials). They included 170 participants with a mean age of 37 years. All participants had positive alcohol screening test upon entry to the trial. At the end, the scores between groups were similar (average difference in scores: -0.6, 1.7 and -2, respectively).
One study found that a brief motivational intervention led to a reduction of alcohol use (by seven or more days in the past month at 6 months). Also this section is not clear; it seems that you described the results only of four studies.

It remains uncertain whether talking therapies affect drinking and drug using in people who have problems with both alcohol and other drugs because of the lack of high quality studies.
