CDC COMMUNITY GUIDE: Reducing Alcohol-Impaired Driving: Multicomponent Interventions with Community Mobilization

CDC

An Evidence-Based Practice

Description

Multicomponent interventions to reduce alcohol-impaired driving can include any or all of a number of components, such as sobriety checkpoints, training in responsible beverage service, education and awareness-raising efforts, and limiting access to alcohol. Interventions that qualified for this review:
1. Implemented multiple programs and/or policies in multiple settings to effect the community environment to reduce alcohol-impaired driving, and
2. Included participation of active community coalitions or task forces in their design or execution (community mobilization)

The Community Preventive Services Task Force recommends the use of multicomponent interventions with community mobilization on the basis of strong evidence of their effectiveness in reducing alcohol-impaired driving.

Results / Accomplishments

Results from the Systematic Reviews:
Six studies qualified for the systematic review.

• Fatal crash outcomes: decreased 9% and 42% (2 studies)
• Nighttime injury crashes: decreased 10% (1 study)
• Crashes among drivers aged 16-20: decreased 45% (1 study)
• There was a small decrease in the rate of crashes among drivers under 21 years of age, however, the actual number of crashes was not reported and the percentage change could not be calculated (1 study).
• Evaluation follow-up periods ranged from 2 to 10 years (median 4 years).
• The reviewed interventions addressed a range of alcohol-related concerns including alcohol-impaired driving, excessive drinking, underage drinking, alcohol-related injuries, and increasing access to alcohol treatment.
• Interventions included responsible beverage service programs and other efforts to limit access to alcohol, such as:
- Regulations controlling alcohol outlet density and enforcement of minimum legal drinking age laws (6 studies)
- Sobriety checkpoints (5 studies)
- Awareness or educational campaigns (5 studies)
- Attention to other driving risks, such as speeding (2 studies)
- Improved access to alcohol treatment (2 studies)
• Most intervention communities had populations between 50,000-100,000. Two cities had populations greater than 500,000.
