OBJECTIVE: To examine from a Canadian population-based perspective the incidence
and etiology of long-term hospital utilization among persons living with
traumatic brain injury (TBI) by age and sex.
DESIGN: Retrospective cohort study.
SETTING: Acute care hospitals in Ontario.
PARTICIPANTS: Index cases of TBI (N=29,269) were identified from the Discharge
Abstract Database for fiscal years 2002/03-2009/10 and were followed up to 36
months after injury.
INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Re-hospitalizations were defined as an admission to an
acute care facility that occurred up to 36 months following index injury.
Diagnoses associated with subsequent re-hospitalizations were examined by age and
RESULTS: 35.5% (n=10,390) of patients with TBI were subsequently hospitalized
during the 3 year follow-up period. Multivariable logistic regression
(controlling for index admission hospital) identified males, older age, mechanism
of injury being a fall, greater injury severity, rural residence, greater
comorbidity and psychiatric comorbidity to be significant predictors of
re-hospitalization in a three year period post injury. The most common causes for
re-hospitalization differed by age and sex.
CONCLUSIONS: Re-hospitalizations after TBI are common. Factors associated with
re-hospitalizations can inform long term post discharge planning. Findings also
support examining causes for re-hospitalization by age and sex.
