Motorcycle crashes are common occurrences in Kentucky, and often result in injury or death. The use of motorcycle helmets may improve injury outcomes. ⋯ Motorcycle drivers who did not wear helmets were more likely to incur a TBI (OR = 4.33, 95% CI: 2.60-7.20), severe head injuries (OR = 4.36, 95% CI: 2.58-7.37), and higher acute care hospital charges (beta = $26,618, 95% CI: $8670-$44,565). Kentucky's failure to require mandatory helmet use may increase incidence of TBI and severe head injuries among motorcyclists, and cost state government millions of dollars to pay for care for uninsured or Medicaid patients.
