Abstract

Aim
Investigate changes in alcohol use and related harm using the first multisite, controlled, longitudinal study of Managed Alcohol Programs (MAPs). MAPs provide regular doses of alcohol, accommodation, social supports and healthcare to unstably housed people with alcohol dependence.


Methods
A multisite, quasi-experimental, longitudinal study was conducted in day centres, shelters and residential programs for unstably housed people. There were 59 MAP participants from six Canadian cities and 116 local controls. Self-reported alcohol consumption and harms were assessed at 0-2, 6 and 12 months. Liver function test results were accessed for MAP participants.


Results
Both groups had similar reductions in mean drinks per day (MAP: -8.11; controls: -8.54 controls, P < 0.001) and days drinking per month (MAP: -2.51 days, P < 0.05; control: -4.81 days, P = 0.0001) over 6–-12 months. Both reduced non-beverage alcohol consumption. MAP participants reported significantly fewer harms at both 0-2 and 6 months than controls. MAP participants had similar total consumption to controls, but spread out over more days (25.41 versus 19.64 days per month, P = 0.001). After leaving a MAP, participants' liver status deteriorated, with increases in both aspartate transaminase and bilirubin levels. MAP sites with effective policies on outside drinking drank less and had fewer harms.


Conclusion
MAP participants drank less hazardously than controls, especially with effective management of non-MAP drinking. Reductions in alcohol use and harms occurred for both groups, although MAP participants reported fewer harms at 0-6 months. Departing an MAP was associated with deterioration in liver status. Although providing stable housing, MAPs did not worsen health or increase alcohol use.

Abstract

Aims
An updated Cochrane systematic review assessed effectiveness of screening and brief intervention to reduce hazardous or harmful alcohol consumption in general practice or emergency care settings. This paper summarises the implications of the review for clinicians.


Methods
Cochrane methods were followed. Reporting accords with PRISMA guidance. We searched multiple resources to September 2017, seeking randomised controlled trials of brief interventions to reduce hazardous or harmful alcohol consumption in people attending general practice, emergency care or other primary care settings for reasons other than alcohol treatment. Brief intervention was defined as a conversation comprising five or fewer sessions of brief advice or brief lifestyle counselling and a total duration of less than 60 min. Our primary outcome was alcohol consumption, measured as or convertible to grams per week. We conducted meta-analyses to assess change in consumption, and subgroup analyses to explore the impact of participant and intervention characteristics.


Results
We included 69 studies, of which 42 were added for this update. Most studies (88%) compared brief intervention to control. The primary meta-analysis included 34 studies and provided moderate-quality evidence that brief intervention reduced consumption compared to control after one year (mean difference −20 g/wk, 95% confidence interval −28 to −12). Subgroup analysis showed a similar effect for men and women.


Conclusions
Brief interventions can reduce harmful and hazardous alcohol consumption in men and women. Short, advice-based interventions may be as effective as extended, counselling-based interventions for patients with harmful levels of alcohol use who are presenting for the first time in a primary care setting.
