Abstract
Objective: To confirm the clinical impression that younger pre-school children (<4 years at time of injury) who are referred to a tertiary care centre for management with moderate-to-severe traumatic brain injury (TBI) have poorer social, cognitive, physical and emotional outcomes compared to older pre-schoolers (4–6 years at time of injury) and to describe the prevalence and severity of their social impairment at 8 years of age.
Methods: This is a retrospective review of pre-schoolers with moderate-to-severe TBI from 1995–2009. Their social, cognitive, physical and emotional outcomes were assessed at 8 years of age using the Mayo-Portland Adaptability Inventory–Paediatric.
Results: Of 130 pre-schoolers enrolled in the database who sustained a TBI < 6 years, 93 were seen at 8 years of age (57 males, 36 females). Younger pre-schoolers (n = 61, mean 2.6 years) had inferior social outcomes (p = 0.04) and cognitive abilities (p = 0.006), trended toward poorer physical outcomes (p = 0.1), with no difference for emotional outcomes (p = 0.2), compared to older pre-schoolers (n = 32, mean 5.0 years). Overall, 19/93 had normal social function, 38/93 had mild impairment, 21/93 had moderate impairment and 15/93 had severe impairment to social function.
Conclusions: Children <4 years at the time of moderate-to-severe TBI have poorer social, cognitive and physical outcomes compared to older pre-schoolers.
