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.
PARTICIPANTS: Index cases of TBI (N=29,269) were identified from the Discharge
Abstract Database for fiscal years 2002/2003 through 2009/2010 and were
followed-up until 36 months after injury.
INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Rehospitalization was defined as admission to an acute
care facility that occurred up to 36 months after index injury. Diagnoses
associated with subsequent rehospitalization were examined by age and sex.
RESULTS: Of the patients with TBI, 35.5% (n=10,390) were subsequently
hospitalized during the 3-year follow-up period. Multivariable logistic
regression (controlling for index admission hospital) identified men, older age,
mechanism of injury being a fall, greater injury severity, rural residence,
greater comorbidity, and psychiatric comorbidity to be significant predictors of
rehospitalization in a 3-year period postinjury. The most common causes for
rehospitalization differed by age and sex.
CONCLUSIONS: Rehospitalization after TBI is common. Factors associated with
rehospitalization can inform long-term postdischarge planning. Findings also
support examining causes for rehospitalization by age and sex.
