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.

Tracheostomy risk factors and outcomes after severe traumatic brain injury.
The researchers sought to determine risk factors associated with tracheostomy placement after severe traumatic brain injury (TBI) and subsequent outcomes among those who did and did not receive a tracheostomy. They concluded that age and insurance status are independently associated with tracheostomy placement, but not with mortality after severe TBI. Tracheostomy placement is associated with increased survival after severe TBI.

Hospital variation in cervical spine imaging of young children with traumatic brain injury.
The authors sought to identify child-level and hospital-level factors associated with performance of cervical imaging of children with traumatic brain injury from falls and abusive head trauma. They found no association between annual hospital volume of injured children and cervical imaging performance.

Sex differences in mortality following isolated traumatic brain injury among older adults.
This retrospective cohort study's objective was to determine the possibility of sex differences in mortality among older adutls following isolated traumatic brain injury (TBI) and to comapre with findings using all TBI. The researchers did not find that women were significantly associated with decreased odds of mortality following isolated TBI.

Surgical clipping versus endovascular coiling for elderly patients presenting with subarachnoid hemorrhage.
The authors studied elderly Medicare patients who underwent treatment for ruptured cerebral aneurysms. They did not demonstrate a difference in mortality, rate of discharge to rehabilitation, and readmissions between surgical clipping and endovascular coiling of ruptured cerebral aneurysms, although clipping was associated with a slightly longer length of stay.

ICU sedation with dexmedetomidine after severe traumatic brain injury.
This study describes the dexmedetomidine dosage and infusion times, as well as the physiological parameters, neurological status and daily narcotic requirements before, during and after dexmedetomidine infusion. Its findings demonstrate that initiation of dexmedetomidine infusion is not associated with a decline in neurological functioning in adults with severe TBI.

Age-related disparities in trauma center access for severe head injuries following the release of the updated field triage guidelines.
Reflecting perceived undertriage to trauma centers (TCs) for older adults, the American College of Surgeons' Committee on Trauma and the Center for Disease Control revised field triage guidelines in 2011 with additional emphasis on direct transport to a Level I or II trauma center. Researchers examined whether age-based disparities in TC care for severe head injury decreased. Although patterns of increased TC treatment for all groups with severe head trauma indicate improvements, age-based disparities persisted.

Computerized "Learn-As-You-Go" classification of traumatic brain injuries using NEISS narrative data.
This study evaluated a "Learn-As-You-Go" machine-learning program. When using this program, the user trains classification models and interactively checks on accuracy until a desired threshold is reached. It found that the time frame to classify tens of thousands of narratives was reduced from a few days to minutes after approximately sixty minutes of training.
