Abstract
Objective
To investigate the effects of age and sex on 30-, 60-, and 90-day hospital readmission
after acute hospital discharge for individuals with traumatic brain injury (TBI).
Design
Retrospective cohort study.
Setting
Acute hospitals and postacute discharge settings.
Participants
Individuals (N=52,877) with Diagnosis Related Group codes of TBI, who were divided
into 4 age groups: 18 to 40, 41 to 65, 66 to 75, and ≥76 years.
Interventions
Not applicable.
Main Outcome Measures
All-cause hospital readmission.
Results
Sex differences in 30-, 60-, and 90-day hospital readmission were found among all
age groups (P<.05 for all). The largest sex differences in hospital readmission were in the 2 oldest
groups (66–75 and ≥76y). For both sexes, the oldest group (≥76y) had the highest adjusted
90-day readmission risk (eg, 90-d readmission: odds ratio, 2.32 [95% confidence interval,
2.01–2.69] for men; odds ratio, 1.96 [95% confidence interval, 1.59–2.43] for women).
Among those readmitted within 90 days, the youngest group (18–40y) had the highest
cumulative readmission percentage (35% for both sexes) within the first week of hospital
discharge.
Conclusions
Age and sex were significantly associated with hospital readmission during the first
90 days postdischarge in our TBI sample. Specifically, those aged 66 to 75 or ≥76
years had the highest readmission risk over 90 days for both sexes. The findings suggest
that clinicians should consider age and sex in discharge planning and for the entire
episode of care for the population with TBI.
