It's Not All Black and White: The Effect of Increasing Severity of Frailty on Outcomes of Geriatric Trauma Patients. The journal of trauma and acute care surgery.More infoFrailty is associated with poor outcomes in trauma patients. However, the spectrum of physiologic deficits, once a patient is identified as frail, is unknown. The aim of this study was to assess the dynamic association between increasing frailty and outcomes among frail geriatric trauma patients.

Local Antibiotic Therapy for Open Long Bone Fractures: Appropriate Prophylaxis or Unnecessary Exposure for the Orthopedic Trauma Patient?. Military medicine, 188(Supplement_6), 407-411.More infoProphylactic local antibiotic therapy (LAbT) to prevent infection in open long bone fracture (OLBF) patients has been in use for many decades despite lack of definitive evidence confirming a beneficial effect.

Outcomes among trauma patients with duodenal leak following primary versus complex repair of duodenal injuries: An Eastern Association for the Surgery of Trauma multicenter trial. The journal of trauma and acute care surgery, 95(1), 151-159.More infoDuodenal leak is a feared complication of repair, and innovative complex repairs with adjunctive measures (CRAM) were developed to decrease both leak occurrence and severity when leaks occur. Data on the association of CRAM and duodenal leak are sparse, and its impact on duodenal leak outcomes is nonexistent. We hypothesized that primary repair alone (PRA) would be associated with decreased duodenal leak rates; however, CRAM would be associated with improved recovery and outcomes when leaks do occur.

S., Galindo, R. M., Silva, A., Coimbra, R., & Berndtson, A. E. (2023). Understanding the Burden of Traumatic Injuries at the United States-Mexico Border: A Scoping Review of the Literature. The journal of trauma and acute care surgery.More infoThe United States-Mexico border is the busiest land crossing in the world and faces continuously increasing numbers of undocumented border crossers. Significant barriers to crossing are present in many regions of the border, including walls, bridges, rivers, canals, and the desert, each with unique features that can cause traumatic injury. The number of patients injured attempting to cross the border is also increasing, but significant knowledge gaps regarding these injuries and their impacts remain. The purpose of this scoping literature review is to describe the current state of trauma related to the US-Mexico border to draw attention to the problem, identify knowledge gaps in the existing literature, and introduce the creation of a consortium made up of representatives from border trauma centers in the Southwestern United States, the Border Region Doing Research on Trauma (BRDR-T) Consortium. Consortium members will collaborate to produce multicenter, up-to-date data on the medical impact of the US-Mexico border, helping to elucidate the true magnitude of the problem and shed light on the impact cross-border trauma has on migrants, their families, and the United States healthcare system. Only once the problem is fully described can meaningful solutions be provided.

Outcomes of Geriatric Burn Patients Presenting to the Trauma Service: How Does Frailty Factor in?. The Journal of surgical research, 293, 327-334.More infoFrailty has been known to negatively affect the outcomes of geriatric trauma patients. However, there is a lack of data on the effect of frailty on the outcomes of geriatric trauma patients with concomitant burn injuries. The aim of our study was to compare the outcomes of frail versus nonfrail geriatric trauma patients with concomitant burn injuries.

Journal of pediatric surgery.More infoEmergent trauma laparotomy is associated with mortality rates of up to 40%. There is a paucity of data on the outcomes of emergent trauma laparotomies performed in the pediatric population.

Emergency readmissions following geriatric ground-level falls: How does frailty factor in?. Injury.More infoGround-level falls (GLFs) in older adults are increasing as life expectancy increases, and more patients are being discharged to skilled nursing facilities (SNFs) for continuity of care. However, GLF patients are not a homogenous cohort, and the role of frailty remains to be assessed. Thus, the aim of this study is to examine the impact of frailty on the in-hospital and 30-day outcomes of GLF patients.
