  1. Sex Differences in Profiles and Outcomes of Patients with Traumatic Brain Injury in a National Rehabilitation Sample Dr. Angela Colantonio PhD, OT Reg. (Ont), FACRMCIHR Research Chair in Gender, Work and Health Vincy Chan MPH, PhD Candidate Tatyana Mollayeva PhD Candidate University of Toronto&Toronto Rehabilitation Institute, University Health Network

  2. Background and Significance Traumatic brain injury (TBI): Damage to brain after birth by traumatic events Leading cause of death, disability worldwide Cost of TBI is considerable, indirect costs expected to increase significantly

  3. Background and Significance Sex differences in TBI population outcomes: Women more likely than men to be discharged to care facilities Well-established association between TBI and depression, anxiety, substance use Comorbidities influence discharge destination However: Paucity of research on TBI outcomes considering sex differences Scarce population-based information on range of health conditions affecting TBI rehabilitation patient outcomes by sex

  4. Specific Aims • Examine sex differences in profiles and outcomes of patients with TBIpatients in a population-based province-wide rehabilitation sample • Investigate the presence of medical comorbidities at admission as well as comorbidities that develop during the rehabilitation stay

  5. Methods Sample: • All patients in inpatient rehabilitation with TBI diagnostic code between 2004/05 and 2007/08 • Only the first inpatient rehabilitation admission for each patient was considered • Data sources: • National Rehabilitation Reporting System (NRS) • Mandatory reporting in Ontario = population-based

  6. National Rehabilitation Reporting System • Clinical outcomes, characteristics of rehabilitation activities • Data from every inpatient rehabilitation bed within acute care or free standing rehab hospitals in Ontario, Canada • Cases grouped by conditions Rehabilitation Client Groupings (RCG) • Inclusion in study: RCG 2.2, 2.21, 2.22 (TBI)

  7. Methods Key Variables: • Demographic: • Age, sex, language, geographic location of residence • Clinical: • pre-admit and post-admit comorbid health conditions, length of stay, total function score and motor and cognitive ratings from the FIM™ Instrument • Environmental: • Informal support, living setting/arrangement at admission and discharge

  8. Results Demographic Characteristics N = 1,257 Majority males (70%) Younger adults ~80% Older adults ~60% Females significantly older than males (60 vs. 50 years)

  9. Results Clinical Characteristics

  10. Average Length of Stay Statistics Significance: *p<.05, **p<.01, ***p<.001

  11. Total Function Score, Motor & Cognitive Rating at Admission Statistics Significance: *p<.05, **p<.01, ***p<.001

  12. Total Function Score, Motor & Cognitive Rating at Discharge Statistics Significance: *p<.05, **p<.01, ***p<.001

  13. Comorbid Health Condition at Admission Statistics Significance: *p<.05, **p<.01, ***p<.001

  14. Most Common Comorbid Health Conditions at Admission • Overall: • Circulatory System (M=31%, F=45%) • Mental Health (M=28%, F=27%) • Nervous System (M=26%, F=30%) • <65 Years: • Mental Health (M=30%, F=24%) • Nervous System (N=25%, F=31%) • 65+ Years: • Circulatory System (M=64%, F=69%) • Nervous System (N=29%, F=30%)

  15. Type of Comorbid Health Condition at Admission Statistics Significance: *p<.05, **p<.01, ***p<.001

  16. Proportion with Mental Health Conditions at Admission Statistics Significance: *p<.05, **p<.01, ***p<.001

  17. Comorbid Health Condition at Discharge Statistics Significance: *p<.05, **p<.01, ***p<.001

  18. Most Common Comorbid Health Conditions at Discharge • Overall: • Mental Health (M=4%, F=5%) • Circulatory System (M=3%, F=5%) • Nervous System (M=4%, F=5%) • <65 Years: • Mental Health (M=4%, F=5%) • Nervous System (N=4%, F=3%) • 65+ Years: • Mental Health (M=5%, F=6%) • Nervous System (N=3%, F=7%)

  19. Type of Comorbid Health Condition at Discharge • Overall • A significantly higher proportion of females (p<.05) had symptoms, signs, and ill-defined conditions • <65 Years • A significantly higher proportion of females (p<.05) had infectious and parasitic conditions and symptoms, signs, and ill-defined conditions • 65+ Years • A significantly higher proportion of females (p<.05) had conditions of the blood and blood-forming organs

  20. Results Environmental Characteristics At admission: Significantly higher proportion of females living alone At admission and at discharge: Significantly higher proportion of males living at home Significantly higher proportion of females living at home with support and in residential care No significant sex differences in informal support at discharge

  21. Summary • There are significant sex differences, in particular, in functional outcomes, comorbidities, and living setting • A significantly higher proportion of females had a comorbid health condition at admission and at discharge • Types of comorbid health conditions differed significantly by sex

  22. Limitations Extensive validation not done on all variables Not all desired variables available Sample limited to patients coded as having a TBI in the NRS Some patients may be coded under other health conditions (e.g., stroke)

  23. Implications • Importance in understanding influence of comorbidities on rehabilitation outcomes by sex: • Inform planning of rehabilitation services • Preparation of community support and services for population at discharge

  24. Future Plans • Additional research will adjust for age in order to determine the influence of age on the demographic and clinical variables
