Pediatric traumatic brain injury (TBI) protocols vary widely among institutions, despite the existence of published guidelines. This study seeks to identify significant differences in management of pediatric TBI across several institutions. Severe pediatric TBI protocols were collected from major US pediatric hospitals through direct communication with trauma staff. Of 24 institutions identified and contacted, 10 did not respond and 5 did not have a pediatric TBI protocol. Pediatric TBI protocols were successfully collected from 9 institutions. These 9 protocols were separated into treatment tiers analogous to those in the 2019 Society of Critical Care Medicine and World Federation of Pediatric Intensive and Critical Care Societies guidelines, and the intervention variables were identified and compared across the 9 institutions. First-line therapies were similar between institutions, including seizure prophylaxis, maintenance of normoglycemia and normothermia, and avoidance of hypoxia, hyponatremia, and hypotension. However, significant variation across institutions was found regarding timing of cerebrospinal fluid drainage, hyperventilation, and neuromuscular blockade. When included in institutional protocols, most therapies are in line with the 2019 guidelines, except for diversion of cerebrospinal fluid, hyperventilation, maintenance of cerebral perfusion pressure, and use of neuromuscular blocking agents. Although these variations may represent differences in style or preference, the optimal timing of these specific treatment variations should be studied to determine the impact of each protocol on clinical outcomes.

Objective: Prior studies have focused on the role of the learning environment on students' decisions to pursue surgery, but few have analyzed the impact of the clerkship curriculum. This study assessed surgical clerkship curricula across United States (US) medical schools and their impact on students' likelihood of pursuing a surgical residency., Design: A cross-sectional survey was developed to assess surgery clerkship characteristics. Questions included clerkship duration, number of offered and required surgical services, method of service assignment, and number of advanced clinical electives (e.g., fourth-year sub-internships) and additional surgical clinical opportunities (e.g., surgical elective rotations). Survey results were merged by the Association of American Medical Colleges with the percentages of students who matched into a surgical specialty. Linear regression models estimated the association of covariates with the percentage of students who (1) matched in surgical specialties, (2) were interested in surgery at medical school matriculation and ultimately matched into surgical residency (retention rate), and (3) were not interested in surgery at medical school matriculation but ultimately matched into surgical residency (recruitment rate)., Setting: The survey was distributed to clerkship directors and coordinators at 66 medical schools through the Association for Surgical Education (ASE) from 5/1/2021 to 8/1/2021., Participants: All US medical schools in the ASE., Results: A total of 21 medical schools responded (34.8% response rate). The overall retention rate was 36.4%, and the overall recruitment rate was 25.0%. Clerkships were 4 to 12 weeks. In 81% of programs, students submitted preferences and were assigned services. The percentage of students applying to surgical specialties was not associated with clerkship duration (p=0.79) or the number of required services (p=0.15), subspecialty services offered (p=0.33), or advanced clinical electives (p=0.24) but was associated with a program's having additional surgical clinical opportunities (p=0.02). Most of these factors were not associated with retention or recruitment rates., Conclusions: Offering more extracurricular surgical clinical opportunities was associated with having more students pursue surgical careers. Though limited by a relatively small sample size, our findings suggest that having shorter clerkships or limited subspecialty offerings may not have a significant influence on students' career choices., (Copyright © 2023 Association of Program Directors in Surgery.
