Objectives: To document service utilization by people with a traumatic brai
n injury at different times postinjury and to identify factors that predict
service use. Design: Cross-sectional study design. Four groups of subjects
were randomly selected from a regional database, according to their time p
ostinjury: 6-18 months; 2-4 years; 6-9 years; and 10-17 years. Subjects: A
total of 119 adults with a traumatic brain injury (TBI) Setting: Hospital a
nd community-based clients in Sydney Australia. Outcome measures: Glasgow O
utcome Scale, Disability Rating Scale; Functional Independence Measure; Lid
combe Psychosocial Disability Scale; number, type, and frequency of service
s used in the previous 12 months. Results: Subjects in all four groups used
a variety of services. The mean number of services used was 4.2, and there
was only a moderate decline in service use over time. The use of medical a
nd allied health services remained high in all four groups. Severity of inj
ury, physical and cognitive disability, and psychosocial disability were al
l predictors of service utilization. Psychosocial disability was strongly a
ssociated with ongoing service utilization. Conclusion: In this study, peop
le with TBI used services well beyond the early stage of recovery Psychosoc
ial disability may be a better predictor of service use than physical and c
ognitive disability alone.
