Sleepy Driver Near-Misses May Predict Accident Risks

This article reports on a cross-sectional, internet-linked study undertaken to quantify the prevalence of self-reported near-miss sleepy driving accidents and their association with self-reported actual driving accidents. The data was gathered at the Dateline NBC News website and results are given on 35,217 (88% of sample) individuals with a mean age of 37.2 (plus or minus13 years) which consisted of 54.8% women, and 87% white persons. The risk of at least one accident increased from 23.2% for people who reported no near-miss sleepy accidents to 44.5% if the respondent report 4 or more near-miss sleepy accidents. Analyses showed that subjects who reported at least one near-miss sleepy accident were 1.13 times as likely to have reported at least one actual accident as subjects reporting no near-miss sleepy accidents. In addition, the summary Epworth Sleepiness Scale (ESS) score had an independent association with having a near-miss or actual accident. The authors conclude that sleepy near-misses may be dangerous precursors to an actual accident. The questionnaire used in the study is appended to the article.
