IMPACT OF MINORITY STATUS ON FUNCTIONAL OUTCOME AND COMMUNITY INTEGRATION FOLLOWING TRAUMATIC BRAIN INJURY

Objective: To determine whether minority status affected short-term an d 1-year functional outcome and community integration for patients wit h traumatic brain injury (TBI) in the TBI Model Systems National Data Base. Design: Prospective study, consecutive sample. Setting: Four ter tiary care rehabilitation centers. Patients: Five hundred and eighty-s ix patients with TBI admitted to one of four TBI Model Systems program s from February 1989 through June 1995. Inclusion criteria for the stu dy included evidence of a TBI, admission to the system hospital emerge ncy department within 8 hours of injury, 19 years of age or older, and acute care and inpatient rehabilitation within the system hospitals. Information was collected for demographics such as race, age, gender, education, employment status, marital status, and data related to the injury such as injury severity, etiology of injury, and payer source. Over half of the sample was white (53.4%) with the 46.6% of minorities composed of blacks (37.2%). Hispanics (7.3%), and Asians (2.0%). Main Outcome Measures: Functional outcome was measured with the Functional Independence Measure (FIM). Disability Rating Scale (DRS), and Commun ity Integration Questionnaire (CIQ). The FIM and DRS were measured at inpatient rehabilitation admission, discharge, and 1 year post injury. The CIQ total score and subscale scores for Home Integration, Social integration, and Productivity were obtained at 1-year post injury, It was hypothesized that minority status would not predict functional out come after acute rehabilitation but would predict functional outcome a nd community integration at 1 year post injury. Results: There were no significant differences between whites and minorities for DRS and FM scores at acute rehabilitation discharge. There were also no significa nt differences between whites and minorities on FIM scores 1 year post injury, but there were significant differences between whites and min orities on the Social Integration and Productivity subscales and total score of the CIQ. Multiple regression indicated that minority status predicted functional outcome for CIQ total score (r=-.28) and two subs cales, Social Integration (r=-.28) and Productivity (r=-.23) even afte r controlling for etiology, severity of injury, age, gender, and funct ional status a rehabilitation discharge. Conclusions: Although minorit y status does not negatively impact recovery of basic mobility and dai ly living skills, it may impact long-term outcome related to community integration as measured by productivity and social integration. Great er outreach and access to postdischarge services and support may be ne eded to optimize community integration outcomes. Further studies are n eeded to determine how best to serve the needs of this segment of the population with TBI.
