Item Aging with Traumatic Brain Injury: Deleterious Effects of Injury Chronicity Are Most Pronounced in Later Life(Mary Ann Liebert, 2021) Rabinowitz, Amanda R.; Kumar, Raj G.; Sima, Adam; Venkatesan, Umesh M.; Juengst, Shannon B.; O’Neil-Pirozzi, Therese M.; Watanabe, Thomas K.; Goldin, Yelena; Hammond, Flora M.; Dreer, Laura E.; Physical Medicine and Rehabilitation, School of MedicineUnderstanding the effects of age on longitudinal traumatic brain injury (TBI) outcomes requires attention to both chronic and evolving TBI effects and age-related changes in health and function. The present study examines the independent and interactive effects of aging and chronicity on functional outcomes after TBI. We leveraged a well-defined cohort of individuals who sustained a moderate/severe TBI and received acute inpatient rehabilitation at specialized centers with high follow up rate as part of their involvement in the TBI Model Systems longitudinal study. We selected individuals at one of two levels of TBI chronicity (either 2 or 10 years post-injury) and used an exact matching procedure to obtain balanced chronicity groups based on age and other characteristics (N = 1993). We found that both older age and greater injury chronicity were related to greater disability, reduced functional independence, and less community participation. There was a significant age by chronicity interaction, indicating that the adverse effects of greater time post-injury were most pronounced among survivors who were age 75 or older. The inflection point at roughly 75 years of age was corroborated by post hoc analyses, dividing the sample by age at 75 years and examining the interaction between age group and chronicity. These findings point to a need for provision of rehabilitation services in the chronic injury period, particularly for those who are over 75 years old. Future work should investigate the underlying mechanisms of this interaction towards the goal of developing interventions and models of care to promote healthy aging with TBI.Item The Feasibility of Telephone-Administered Cognitive Testing in Individuals 1 and 2 Years after Inpatient Rehabilitation for Traumatic Brain Injury(Mary Ann Liebert, 2018-05-15) Dams-O'Connor, Kristen; Sy, Karla Therese L.; Landau, Alexandra; Bodien, Yelena; Dikmen, Sureyya; Felix, Elizabeth R.; Giacino, Joseph T.; Gibbons, Laura; Hammond, Flora M.; Hart, Tessa; Johnson-Greene, Doug; Lengenfelder, Jeannie; Lequerica, Anthony; Newman, Jody; Novack, Thomas; O'Neil-Pirozzi, Therese M.; Whiteneck, Gale; Physical Medicine and Rehabilitation, School of MedicineTraumatic brain injury (TBI) often results in cognitive impairment, and trajectories of cognitive functioning can vary tremendously over time across survivors. Traditional approaches to measuring cognitive performance require face-to-face administration of a battery of objective neuropsychological tests, which can be time- and labor-intensive. There are numerous clinical and research contexts in which in-person testing is undesirable or unfeasible, including clinical monitoring of older adults or individuals with disability for whom travel is challenging, and epidemiological studies of geographically dispersed participants. A telephone-based method for measuring cognition could conserve resources and improve efficiency. The objective of this study is to examine the feasibility and usefulness of the Brief Test of Adult Cognition by Telephone (BTACT) among individuals who are 1 and 2 years post-moderate-to-severe TBI. A total of 463 individuals participated in the study at Year 1 post-injury, and 386 participated at Year 2. The sample was mostly male (73%) and white (59%), with an average age of (mean ± standard deviation) 47.9 ± 20.9 years, and 73% experienced a duration of post-traumatic amnesia (PTA) greater than 7 days. A majority of participants were able to complete the BTACT subtests (61-69% and 56-64% for Years 1 and 2 respectively); score imputation for those unable to complete a test due to severity of cognitive impairment yields complete data for 74-79% of the sample. BTACT subtests showed expected changes between Years 1-2, and summary scores demonstrated expected associations with injury severity, employment status, and cognitive status as measured by the Functional Independence Measure. Results indicate it is feasible, efficient, and useful to measure cognition over the telephone among individuals with moderate-severe TBI.Item Post-Inpatient Brain Injury Rehabilitation Outcomes: Report from the National OutcomeInfo Database(Mary Ann Liebert, Inc., 2016-07-15) Malec, James F.; Kean, Jacob; Physical Medicine and Rehabilitation, School of MedicineThis study examined outcomes for intensive residential and outpatient/community-based post-inpatient brain injury rehabilitation (PBIR) programs compared with supported living programs. The goal of supported living programs was stable functioning (no change). Data were obtained for a large cohort of adults with acquired brain injury (ABI) from the OutcomeInfo national database, a web-based database system developed through National Institutes of Health (NIH) Small Business Technology Transfer (STTR) funding for monitoring progress and outcomes in PBIR programs primarily with the Mayo-Portland Adaptability Inventory (MPAI-4). Rasch-derived MPAI-4 measures for cases from 2008 to 2014 from 9 provider organizations offering programs in 23 facilities throughout the United States were examined. Controlling for age at injury, time in program, and time since injury on admission (chronicity), both intensive residential (n = 205) and outpatient/community-based (n = 2781) programs resulted in significant (approximately 1 standard deviation [SD]) functional improvement on the MPAI-4 Total Score compared with supported living (n = 101) programs (F = 18.184, p < 0.001). Intensive outpatient/community-based programs showed greater improvements on MPAI-4 Ability (F = 14.135, p < 0.001), Adjustment (F = 12.939, p < 0.001), and Participation (F = 16.679, p < 0.001) indices than supported living programs; whereas, intensive residential programs showed improvement primarily in Adjustment and Participation. Age at injury and time in program had small effects on outcome; the effect of chronicity was small to moderate. Examination of more chronic cases (>1 year post-injury) showed significant, but smaller (approximately 0.5 SD) change on the MPAI-4 relative to supported living programs (F = 17.562, p < 0.001). Results indicate that intensive residential and outpatient/community-based PIBR programs result in substantial positive functional changes moderated by chronicity.
