Objectives: To examine presentations and prevalence of head injury among elder victims of blunt trauma and to estimate the prevalence of occult injuries associated with a normal level of consciousness, absence of neurologic deficit, and no evidence of significant skull fracture. Methods: The study population consisted of all patients aged 65 years or older enrolled in the National Emergency X-Radiography Utilization Study (NEXUS) II head injury cohort. The authors assessed the prevalence and patterns of intracranial injuries among this cohort and compared the prevalence of specific presenting signs and symptoms among injured and uninjured patients. An occult injury subcohort was also constructed, and injury prevalence was examined among this group. Results: A total of 1,934 elder patients were identified among the 13,326 subjects in NEXUS II (14.5%). Significant intracranial injury, defined as an injury that typically requires procedural intervention or is associated with persistent neurologic impairment or long-term disability, was found in 178 elder patients (9.2%; 95% confidence interval = 8.0% to 10.6%) as compared with 697 individuals among 11,392 younger patients (6.1%; 95% confidence interval = 5.7% to 6.6%). Focal neurologic deficits were present in 55.8% of elder patients with injury. Prevalence of specific injuries among elder and younger patients, respectively, included the following: subdural hematoma, 4.4% and 2.4%; contusion, 4.0% and 3.2%; epidural hematoma, 0.5% and 1.0%; and depressed skull fracture, 0.2% and 0.5%. Forty-two elder patients (2.2%) had an occult injury, compared with only 92 younger patients (0.8%). Conclusions: Elder patients with head trauma are at higher risk of developing a significant intracranial injury, including subdural and epidural hematoma. An occult presentation is also more common in elders.
All academic medical specialties have the obligation to continuously create new knowledge that will improve patient care and outcomes. Emergency medicine (EM) is no exception. Since its origins over 50 years ago, EM has struggled to fulfill its research mission. EM ranks last among clinical specialties in the percentage of medical school faculty who are National Institutes of Health (NIH)-funded principal investigators (PIs; 1.7%) and the percentage of medical school departments with NIH-funded PIs (33%). Although there has been a steady increase in the number of NIH-funded projects and total NIH dollars, the slowing growth in the number of NIH-funded PIs and lack of growth in the number of EM departments with NIH-funded PIs is cause for concern. In response, the Association of Academic Chairs of Emergency Medicine (AACEM) Research Task Force proposes a set of 2030 strategic goals for the EM research enterprise that are based on sustaining historic growth rates in NIH funding. These goals have been endorsed by the AACEM Executive Committee and the boards of Society for Academic Emergency Medicine (SAEM), American College of Emergency Physicians (ACEP), and American Academy of Emergency Medicine (AAEM). The 2030 strategic goals include 200 NIH-funded projects led by 150 EM PIs in at least 50 EM departments with over $100M in annual funding resulting in over 3% of EM faculty being NIH-funded PIs. Achieving these goals will require a targeted series of focused strategies to increase the number of EM faculty who are competitive for NIH funding. This requires a coordinated, intentional effort with investments at the national, departmental, and individual levels. These efforts are ideally led by medical school department chairs, who can create the culture and provide the resources needed to be successful. The specialty of EM has the obligation to improve the health of the public and to fulfill its research mission.
Major negative life events, such as trauma exposure, can play a key role in igniting or exacerbating psychopathology. However, few disorders are diagnosed with respect to precipitating events, and the role of these events in the unfolding of new psychopathology is not well understood. The authors conducted a multisite transdiagnostic longitudinal study of trauma exposure and related mental health outcomes to identify neurobiological predictors of risk, resilience, and different symptom presentations.
