    Post-traumatic brain injury fatigue (PTBIF) is a major problem in the years after traumatic brain injury (TBI), yet little is known about its persistence and resolution. The objective of the study was to identify factors related to PTBIF remission and resolution. TBI Model System registrants at five centres participated in interviews at either one and two years post-injury (Y1-2 Cohort), or two and five years post-injury (Y2-5 Cohort). Characteristics of participants with PTBIF remission were compared to those with PTBIF persistence. Variables studied included the presence of and changes in disability, sleep dysfunction, mood, and community participation. The Functional Independence Measure did not differ significantly between groups or over time. In the Y1-2 Cohort the Fatigue Resolved group scored significantly better on the Disability Rating Scale and Pittsburgh Sleep Quality Index. In the Y2-5 Cohort the Fatigue Resolved group scored significantly higher on a measure of community participation. It was concluded that fewer than half of the sample in each cohort experienced a remission of PTBIF between time points. Persistence of PTBIF 1–2 years post-injury is associated with disability, sleep disturbance, and depression while persistence of fatigue beyond 2 years post-injury appears to be related to participation level, underscoring the potential impact of effective surveillance, assessment, and treatment of this condition in optimising life after TBI. Differences in fatigue progression may point to the presence of different types of PTBIF.

    Factors Associated with the Remission of Insomnia After Traumatic Brain Injury: A Traumatic Brain Injury Model Systems Study
    (Taylor & Francis, 2020) Lequerica, Anthony H.; Weber, Erica; Dijkers, Marcel P.; Dams-O’Connor, Kristen; Kolakowsky-Hayner, Stephanie A.; Bell, Kathleen R.; Bushnik, Tamara; Goldin, Yelena; Hammond, Flora M.; Physical Medicine and Rehabilitation, School of Medicine
    Objective: To examine the factors associated with the remission of insomnia by examining a sample of individuals who had insomnia within the first two years after traumatic brain injury (TBI) and assessing their status at a secondary time point. Design and Methods: Secondary data analysis from a multicenter longitudinal cohort study. A sample of 40 individuals meeting inclusion criteria completed a number of self-report scales measuring sleep/wake characteristics (Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Insomnia Severity Index, Sleep Hygiene Index), fatigue and depression (Multidimensional Assessment of Fatigue, Patient Health Questionnaire-9), and community participation (Participation Assessment with Recombined Tools-Objective). One cohort was followed at 1 and 2 years post-injury (n = 19) while a second cohort was followed at 2 and 5 years post-injury (n = 21). Results: Remission of insomnia was noted in 60% of the sample. Those with persistent insomnia had significantly higher levels of fatigue and depression at their final follow-up and poorer sleep hygiene across both follow-up time-points. A trend toward reduced community participation among those with persistent insomnia was also found. Conclusion: Individuals with persistent post-TBI insomnia had poorer psychosocial outcomes. The chronicity of post-TBI insomnia may be associated with sleep-related behaviors that serve as perpetuating factors.

    Relationship of patient characteristics and inpatient rehabilitation services to 5-year outcomes following spinal cord injury: A follow up of the SCIRehab project
    (Taylor & Francis, 2021) Monden, Kimberley R.; Hidden, Julie; Eagy, C.B.; Hammond, Flora M.; Kolakowsky-Hayner, Stephanie A.; Whiteneck, Gale G.; Medicine, School of Medicine
    Objective: To examine associations of patient characteristics and treatment quantity delivered during inpatient spinal cord injury (SCI) rehabilitation with outcomes at 5 years post-injury and compare them to the associations found at 1 year post-injury. Design: Observational study using Practice-Based Evidence research methodology in which clinicians documented treatment details. Regression modeling was used to predict outcomes. Setting: Five inpatient SCI rehabilitation centers in the US. Participants: Participants were 792 SCIRehab participants who were >12 years of age, gave informed consent, and completed both a 1-year and 5-year post-injury interview. Outcome measures: Outcome data were derived from Spinal Cord Injury Model Systems (SCIMS) follow-up interviews at 5 years post-injury and, similar to the 1-year SCIMS outcomes, included measures of physical independence, societal participation, life satisfaction, and depressive symptoms, as well as place of residence, school/work attendance, rehospitalization, and presence of pressure ulcers. Results: Consistent with 1-year findings, patient characteristics continue to be strong predictors of outcomes 5-years post-injury, although several variables add to the prediction of some of the outcomes. More time in physical therapy and therapeutic recreation were positive predictors of 1-year outcomes, which held less true at 5 years. Greater time spent with psychology and social work/case management predicted greater depressive symptomatology 5-years post-injury. Greater clinician experience was a predictor at both 1- and 5 -years, although the related positive outcomes varied across years. Conclusion: Various outcomes 5-years post-injury were primarily explained by pre-and post-injury characteristics, with little additional variance offered by the quantity of treatment received during inpatient rehabilitation.
