A major new study published June 15, 2026, in the Canadian Medical Association Journal (CMAJ), and found in the PubMed database, reveals a striking inequity: women hospitalized with traumatic brain injury (TBI) in Ontario are significantly less likely than men to be admitted to specialized (Level I or II) trauma centers. After adjusting for age, injury severity, comorbidities, and income, women’s odds for prompt treatment remain 26% lower (OR 0.74) than that of men.
The finding echoes earlier work: a 2022 US study found that female trauma patients, including those with TBI, experienced longer delays to reach trauma care than men even after accounting for injury severity and type. An accompanying editorial was pointedly titled “Sex Disparities in Trauma Care -Why Are the Women Waiting?” Other U.S. research similarly documents women being undertriaged in emergency departments despite comparable injuries.
Yet context is essential. Per CDC data reported in 2018 and 2020, males were nearly two times more likely to be hospitalized for a TBI (79.9 age-adjusted rate versus 43.7) and three times more likely to die from one than females (28.3 versus 8.4). Even in the Ontario study, men had more severe head trauma (33% vs 25%). The disparity in care is real and demands attention, but men remain more likely to sustain, and die from, TBI overall.
