Article Abstract
Purpose: vAdult trauma literature indicates hemothorax volume >300 mL requires thoracic drainage. Due to a paucity of pediatric literature, we aim to analyze pediatric traumatic hemothorax management and calculate a volume threshold requiring chest tube placement.
Methods: Pediatric traumatic hemothorax cases from two level 1 trauma centers were analyzed. Management was categorized into successful observation (SO), chest tube placement (CTP), and failure of initial observation (FO). Hemothorax volume was calculated using Mergo's formula: dxl. d = greatest depth on transverse cuts. l = length on sagittal cuts. Hospital course, postoperative and long-term outcomes were measured up to 1 year.
Results: 406 traumatic thoracic cases were identified, with 74 hemothoraces analyzed: 32(43%) SO, 38(51%) CTP, 4(6%) initial operation, 10(12%) FO. We observed increases in injury severity score (p=0.020) and thoracic abbreviate injury scale (p<0.001) in CTP versus SO. Presenting tachypnea was not associated with chest tube placement (p=0.632). Statistically higher hemothorax volume was found in CTP vs SO (142.7 ml vs 19.5 ml, p<0.001). Utilizing ROC Curve analysis, >55mL measured with Mergo's formula predicted chest tube placement (p=0.001). Chest tube placement was associated with increased mechanical ventilation requirement (p<0.001), hospital length of stay (LOS) (p<0.001), and ICU LOS (p<0.001). No patients developed delayed empyema from retained hemothorax.
Conclusions: This is the largest cohort of pediatric traumatic hemothoraces and first in the literature to calculate volume threshold requiring chest tube placement. Judicious application of hemothorax volume calculation and overall injury score may assist in the decision making of pediatric traumatic hemothorax management.
Type Of Study: Retrospective Observational Cohort Study LEVEL OF EVIDENCE: Level 3 evidence.

Findable, Accessible, Interoperable, and Reusable (FAIR) data advances are becoming more common and more important across research fields given the large amount of research data in need of synthesis and application. Many novel methods improve the efficiency and accuracy of data reuse, combination, and synthesis, which is necessary given that there are over 500 published randomized controlled trials of posttraumatic stress disorder treatments in adults; however, these methods are still relatively new to the field of traumatic stress research. We provide a brief overview of relevant FAIR data efforts from other fields and within trauma health care and research; share examples of trauma-related FAIR data efforts to demonstrate recent advances and challenges; and suggest potential next steps to continue making trauma data more FAIR.

Background: Repair strategies for pediatric vascular injuries must consider vascular growth and intervention durability. Endovascular interventions are increasingly utilized in pediatrics, particularly in unstable patients or for injuries in surgically morbid regions. This study describes a single-center experience with endovascular stenting in adolescent pediatric trauma.

Resident macrophages play integral roles in maintaining tissue homeostasis and function. In the skin, prenatally seeded, specialized macrophages patrol sensory nerves and contribute to their regeneration after injury. However, mechanisms underlying the long-lasting postnatal commitment of these nerve-associated macrophages remain largely elusive.

Background: Many children and adolescents who undergo solid organ transplants (SOT) develop post-traumatic stress (PTS) symptoms. Despite its prevalence and strong association with long-term impairments in quality of life, PTS is often overlooked as a major co-morbidity in many transplant programs. To address this unmet need, the purpose of this study was to explore the factors that impede or facilitate awareness of PTS, access to resources, and readiness to engage with mental health services.

Prior authorization requirements by health insurance plans have become a barrier to healthcare delivery in the United States in terms of clinical efficiency, patient and provider experience. Surveyed physicians report associations with care delays, reduced clinical effectiveness and compromised patient outcomes. In this systematic review, we synthesized the published evidence regarding harmful effects of prior authorization on disease management and patient outcomes.
