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:

Implemented multiple programs and/or policies in multiple settings to effect the community environment to reduce alcohol-impaired driving, and
Included participation of active community coalitions or task forces in their design or execution (community mobilization)

Impact

The Community Preventive Services Task Force (CPSTF) 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

Six studies qualified for the systematic review.
-42% decrease in alcohol-related crashes (1 studies)
-9% decrease in likelihood that drivers are alcohol-impaired
-Nighttime injury crashes: decreased 10% (1 study)
-Alcohol-related 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).

An Evidence-Based Practice meets the following HCI criteria:

  1. The program description includes at a minimum: the sponsoring organization, program goals, program implementation steps, and outcomes that have demonstrated program success in achieving the program goal in one or more localities.
  2. The results from an evaluation of the program include quantitative measures showing improvement in the outcome(s) of interest after the implementation of the program (i.e. increase in smoking cessation, not just the delivery of a smoking cessation program). The outcome measure(s) is/are compared at relevant time periods before and after the intervention or program implementation. Alternatively, the evaluation study compares the outcome(s) between an intervention group and an appropriate control group.
  3. The study is of peer-review quality and presents numbers in a scientific manner; measurements of precision and reliability are included (e.g. confidence intervals, standard errors), results from statistical tests show a significant difference or change in the outcome measure(s), and relevant point estimates and p-values are presented. Note: if the results from an evaluation of a program are presented in a scientific manner and the outcome measure is improved compared to the baseline measurement or the control group but the difference is not statistically significant, the practice is classified as effective and not evidence-based.
