ADHD and Driving

iStock-172476633Teenagers are well-known for their propensity to have car accidents. Now comes a study Rick and I discuss on PodMed this week and published in JAMA Pediatrics that identifies ADHD as a likely big contributor to motor vehicle crashes, raising the issue for both parents and society at large of the need to find out why, and develop strategies to help.

This retrospective study compared a bunch of data relative to teenage driving, including age at which a driver's license was obtained, presence of ADHD, medication use for ADHD, and a police-reported crash, between almost 2500 adolescents with the condition versus almost 16,000 without. Median age of subjects at the end of the analysis was just over 22 years.

The study found that those with ADHD were 36% more likely to have a motor vehicle accident than those without the condition. This did not vary by age, sex, or over time. Somewhat disturbingly, a minority of the study subjects were prescribed medication for ADHD, so attempting to assess whether crash risk is modified by medication use isn't very robust given the numbers. Rick and I agree that this study points out a clear need to find out why teens with ADHD are at increased risk and to develop interventions.

Other topics this week include Glucose Self-monitoring in Non–Insulin-Treated Patients With Type 2 Diabetes in JAMA Internal Medicine, and Association of Adverse Events With Antibiotic Use in Hospitalized Patients in the same journal. From NEJM,Health Effects of Overweight and Obesity in 195 Countries over 25 Years. Until next week, y'all live well.
