Sex differences in in-hospital complications among older adults after traumatic brain injury.
This study examined sex differences in in-hospital complications among older adults after traumatic brain injury (TBI). Previous evidence has suggested that women have better outcomes than men after TBI. A retrospective cohort study was conducted of adults aged 65 years and older treated for moderate to severe TBI at R. Adams Cowley Shock Trauma Center from 1996 to 2012. The investigators identified TBI using ICD-9 CM codes and inclusion in the study required an abbreviated injury scale head score of 3 or greater, abbreviated injury scale scores for other body regions of 2 or greater, and a blunt injury mechanism. Out of 2511 patients, 51.1% were men, and 25.1% developed an in-hospital complication. Men had a complication rate of 28.1% versus 22.0% for women.

Racial differences in discharge location after a traumatic brain injury among older adults.
The purpose of this retrospective cohort study was to determine if there were racial differences in discharge location among older adults treated for traumatic brain injury (TBI) at a level 1 trauma center. The authors concluded that in this group of Medicare-eligible older adults, blacks were more likely to be discharged to inpatient rehabilitation compared to whites.

Bleeding and thromboembolism after traumatic brain injury in the elderly: a real conundrum.
The objectives of this study were to evaluate the incidence of bleeding, recurrent traumatic brain injury (TBI), and thromboembolic (TE) events after an initial TBI in older adults and to identify which factors contribute to this risk. The researchers found that, among Medicare patients hospitalized with TBI, the incidence of TE events was significantly higher than that of bleeding or recurrent TBI. They identified specific risk factors of bleeding and TE events, which may guide care of older adults after TBI.

Risk of depression after traumatic brain injury in a large national sample.
The goal of this study was to estimate the risk of depression post-traumatic brain injury (TBI) among adults 18 years of age and older and to identify risk factors associated with developing depression post-TBI. Claims data for privately insured and Medicare Advantage enrollees was used. Results showed that history of neuropsychiatric disturbances pre-TBI was the strongest predictor of depression post-TBI. The risk of depression increases substantially post-TBI. Groups at increased risk include those with a history of neuropsychiatric disturbances, older adults, and men. This study highlights the importance of long-term monitoring for depression post-TBI.

Early heart rate variability and electroencephalographic abnormalities in acutely brain-injured children who progress to brain death.
This study retrospective case-control study explored the hypothesis that lower heart rate variability in brain-injured children is an early indicator of autonomic system failure and predicts progression to brain death. The association between heart rate variability and markers of brain dysfunction between brain-injured children who progressed to brain death and those who survived is also examined. Heart rate variability in patients was estimated using 5-minute electrocardiogram segments. Patients who progressed to brain death exhibited significantly lower heart rate variability in the time and frequency domains. Heart rate variability was significantly lower in those patients with discontinuous or attenuated/featureless electroencephalogram than those with slow/disorganized background. The researchers conclude that these findings support the concept of autonomic system failure as an early indicator of impending brain death, and that decreased heart rate variability is associated with markers of central nervous system dysfunction, such as electroencephalogram abnormalities.

Risk of mortality in individuals with hip fracture and traumatic brain injury.
Researchers estimated the prevalence of TBI (traumatic brain injury) with individuals hospitalized with hip fracture and their all-cause mortality. The population studied were Medicare beneficiaries aged 65 and older from 2006 to 2010. They concluded that there was a higher risk of death with individuals who had TBI than those who had only a hip fracture.

Sleep, sleep disorders, and circadian health following mild traumatic brain injury in adults: review and research agenda.
A rapidly expanding scientific literature supports the frequent co-occurrence of sleep and circadian disturbances following mild traumatic brain injury (mTBI). In this paper, the authors review relevant literature and present a research agenda to 1) advance understanding of the reciprocal relationships between sleep and circadian factors and mTBI sequelae and 2) advance rapidly the development of sleep-related treatments in this population.

Safety of antidepressant classes used following traumatic brain injury among Medicare beneficiaries: a retrospective cohort study.
The objective of this study was to compare the risk of several adverse events associated with use of the three most commonly used classes of antidepressants following Traumatic Brain Injury (TBI) in older adults. One of the study’s conclusions was that compared to tricyclic antidepressants, selective serotonin reuptake inhibitor use was associated with increased risk of hemorrhagic stroke.

Race/ethnicity and retention in traumatic brain injury outcomes research: a traumatic brain injury model systems national database study.
The purpose of this study was to investigate the contribution of race/ethnicity to retention in traumatic brain injury (TBI) research at 1 to 2 years postinjury. The findings emphasized the importance of investigating retention rates separately for blacks and Hispanics rather than combining them or grouping either with other races or ethnicities. The results also suggested the need for implementing procedures to increase retention of Hispanics in longitudinal TBI research.

Trend of age-adjusted rates of pediatric traumatic brain injury in U.S. emergency departments from 2006 to 2013.
The objective of this study was to use the 2006(-)2013 Nationwide Emergency Department Sample (NEDS) database to describe trends of age-adjusted rates of pediatric traumatic brain injuries (TBI) treated in U.S. emergency departments. The investigators found that the overall age-adjusted rates of pediatric TBI-related emergency department (ED) visits increased from 2006 to 2013, which was largely caused by pediatric mild TBIs, especially unspecified injury to the head (ICD-9-CM code 959.01) and concussion.

Outcomes of protocolised analgesia and sedation in a neurocritical care unit.
Researchers conducted a retrospective cohort study of 1197 mechanically ventilated patients admitted to a 12-bed neurocritical care unit (NCCU) over four years in order to evaluate the effect of an analgesia-based sedation protocol on medication use and costs in the NCCU. The protocol resulted in increased in fentanyl use and decreased in propofol use, but their findings indicate no effect on healthcare utilization, healthcare costs, or in-hospital mortality. Based on these results, the researchers suggest that similar NCCUs should consider using population-specific protocols to manage analgesia and sedation.

Fever burden and health-related quality of life after intracerebral hemorrhage.
In this prospective observational cohort study, the investigators tested the hypothesis that increased burden of fever is independently associated with decreased health-related quality of life (HRQoL) at follow-up. The authors found that each additional day with a fever was predictive of worse HRQoL domains of Cognitive Function and Mobility after intracerebral hemorrhage up to 1 year. They suggest that HRQoL outcomes may be a sensitive and powerful way to measure the efficacy of fever control in future research.

Implementation of the Canadian CT Head Rule and Its association with use of computed tomography among patients with head injury.
The researchers evaluated the association of implementation of the Canadian CT Head Rule on head computed tomography (CT) imaging in community emergency departments (EDs). They found that a multicomponent implementation of the Canadian CT Head Rule was associated with a modest reduction in CT use and an increased diagnostic yield of head CTs for adult trauma encounters in community EDs.
