Question
Do mass media campaigns result in reduced drunk-driving and alcohol-related crashes?Study Design
Systematic review with meta-analysis.Main results
Eight of 11 studies identified met inclusion criteria. Mass media campaigns on drink driving reduce alcohol-related crashes in the period during or after the campaign (median decease: 13%; interquartile range [IQR] 6% to 14%; see Results table). Mass media campaigns reduced crashes resulting in injury by a median of 10% (IQR 6% to 15%). Mass media campaigns resulted in large savings in medical costs, property damage and productivity (Victoria campaign cost $403,174 per month versus savings of $8,324,532 per month; Wichita campaign cost $454,060 versus savings of $3,431,305; Kansas City campaign cost $322,660 versus savings of $3,676,399). There were no significant differences in outcomes among message types emphasising legal, social or health consequences of drunk-driving.Authors' conclusions
Mass media campaigns significantly reduce drunk-driving and alcohol-related crashes. These campaigns result in large savings. |
