Population-based, inception cohort study of the incidence, course, and prognosis of mild traumatic brain injury after motor vehicle collisions.
OBJECTIVE To determine the incidence , course , and prognosis of adult mild traumatic brain injury ( MTBI ) caused by motor vehicle collisions . DESIGN Prospect i ve , population -based , inception cohort study . SETTING The province of Saskatchewan , Canada , with a population of about 1,000,000 inhabitants . PARTICIPANTS All adults ( N=1716 ) incurring an MTBI in a motor vehicle collision between November 1997 and December 1999 in Saskatchewan . INTERVENTIONS Not applicable . MAIN OUTCOME MEASURES Age- and sex-stratified incidence rates , time to self-reported recovery , and prognostic factors over a 1-year follow-up . RESULTS Of 7170 adults injured in a motor vehicle collision over the 2-year inception period , 1716 ( 24 % ) met our cohort definition of MTBI . There were more women affected ( 53 % ) , and MTBI was most common in the 18- to 23-year-old group . Most were not hospitalized ( 73 % ) , but 28 % reported loss of consciousness and 23 % reported posttraumatic amnesia . The annual incidence of MTBI per 100,000 adults was 106.1 ( 95 % confidence interval [ CI ] , 98.9 - 113.6 ) in the first year and 118.3 ( 95 % CI , 110.8 - 126.3 ) in the second year of the study . The 1-year follow-up rate was 84 % . The median time to recovery was 100 days ( 95 % CI , 97 - 103 ) , and about 23 % reported not having recovered by 1 year . Factors associated with delayed recovery included being older than 50 years , having less than a high school education , having poor expectations for recovery , having depressive symptoms , having arm numbness , having hearing problems , having headaches , having low back pain , and having thoracic back pain . Loss of consciousness and posttraumatic amnesia were not associated with recovery . CONCLUSIONS MTBI affects almost a quarter of persons reporting an injury after a traffic collision . The median time to recovery is 100 days , but 23 % have still not recovered by 1 year . A mix of biopsychosocial factors is associated with recovery , including a strong effect of poor expectations for recovery
