Objective:
This study investigated the prevalence of posttraumatic stress among survivors of serious injury-producing car crashes.
Methods:
This population-based prospective cohort study, conducted in New Zealand, recruited hospitalized car occupants (passengers and drivers) as well as nonhospitalized drivers after a crash in which at least one occupant was hospitalized. Fifty-nine hospitalized passengers (62%) and 209 drivers (72%) completed five- and 18-month interviews. The Impact of Event Scale assessed symptoms of posttraumatic stress.
Results:
At five months 28% of hospitalized passengers, 24% of hospitalized drivers, and 24% of nonhospitalized drivers reported symptoms consistent with posttraumatic stress disorder. At 18 months, 23% of hospitalized passengers, 11% of hospitalized drivers, and 7% of nonhospitalized drivers reported significant levels of stress.
Conclusions:
Strategies to prevent disabling sequelae of crashes must address the needs of hospitalized and nonhospitalized survivors.
