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 Longitudinal Effects of Medical Comorbidities on Functional Outcome and Life Satisfaction After Traumatic Brain Injury: An Individual Growth Curve Analysis of NIDILRR Traumatic Brain Injury Model System Data(Wolters Kluwer, 2019-09-01) Malec, James F.; Ketchum, Jessica M.; Hammond, Flora M.; Corrigan, John D.; Dams-O'Connor, Kristen; Hart, Tessa; Novack, Thomas; Dahdah, Marie; Whiteneck, Gale G.; Bogner, Jennifer; Physical Medicine and Rehabilitation, School of MedicineObjective: To explore associations of specific physical and neuropsychiatric medical conditions to motor and cognitive functioning and life satisfaction over the first 10 years following traumatic brain injury (TBI). Setting: Telephone follow-up through six TBI Model System centers. Participants: 404 individuals or proxies with TBI enrolled in the TBI Model System longitudinal study participating in 10 year follow-up. Design: Individual growth curve analysis. Main Measures: FIM™ Motor and Cognitive subscales, Life Satisfaction Scales, Medical and Mental Health Co-Morbidities Interview. Results: Hypertension, diabetes, cancers, rheumatoid arthritis, and anxiety negatively affected the trajectory of motor functioning over time. Diabetes, cancers, chronic bronchitis, anxiety, and depression negatively impacted cognitive functioning. Numerous neuropsychiatric conditions (sleep disorder, alcoholism, drug addiction, anxiety, panic attacks, PTSD, depression, bipolar disorder), as well as hypertension, liver disease, and cancers diminished life satisfaction. Other medical conditions had a negative effect on functioning and satisfaction at specific follow-up periods. Conclusion: Natural recovery after TBI may include delayed onset of functional decline or early recovery followed by progressive deterioration and is negatively affected by medical comorbidities. Results contribute to the growing evidence that TBI is most appropriately treated as a chronic medical condition complicated by a variety of comorbid conditions.
