Abstract
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.
