Objective: Standardized training and education are priorities for improving system-level quality and outcomes for pediatric trauma patients. The objective of this study is to identify common educational needs of pediatric trauma clinicians in the United States and the gaps in currently available education courses, to inform future curriculum development. Methods: An anonymous, IRB-approved, 30-item cross-sectional survey was developed and distributed to pediatric trauma clinicians via e-mail. Demographic and quantitative data were analyzed with descriptive statistics. Open-ended responses were analyzed using reflexive thematic analysis. Results: Two hundred four surveys were analyzed. Respondents were faculty physicians (40.7%), nurses (23.5%), trauma program managers (18.6%), advanced practice providers (11.3%), EMS (4.4%), and trainee physicians (1.5%) representing thirty-seven states. 70% worked at a pediatric trauma center. 65% had taken the ATLS course, but only 50% felt that the course prepared them to care for pediatric trauma patients. 97% had taken PALS, but only 45% felt the course prepared them for pediatric trauma care. Respondents ranked comfort with specific pediatric trauma skills. Confidence was lowest for chest tube placement (mean=5.7/10) and dosing intubation medications (6.1/10). Confidence was highest for tourniquet placement (8.2/10) and assigning a GCS to a school-aged child or teen (8.1/10). Qualitative themes included: (1) Neither ATLS nor PALS provide comprehensive pediatric trauma education; (2) Comfort with pediatric trauma comes from experience rather than course completion; (3) There is a desire for additional pediatric-specific education, and (4) Multiple specific topics were identified as educational needs. Conclusion: ATLS and PALS alone do not meet the need for comprehensive pediatric trauma education in the United States. Experience is most helpful for proficiency, putting low-volume centers at a disadvantage. Pediatric-specific trauma education is desired, including simulation-based courses and app-based reference materials. Pediatric procedural skills, age-specific assessment and physiology, and evidence-based best practices should be targeted.

Purpose: The anatomic position of the appendix may influence both the clinical presentation and diagnostic imaging accuracy in pediatric appendicitis, but its impact remains uncertain. This study aimed to determine the prevalence of retrocecal appendicitis in children and to evaluate whether appendix positioning affects ultrasound diagnostic performance or clinical outcomes. Methods: This was a retrospective cohort study including all children 0 to 18 years of age who presented to the Mayo Clinic Rochester Emergency Department between 2018 and 2023 and were diagnosed with appendicitis during their evaluation or subsequent hospitalization. Appendix location was determined by imaging or surgical documentation. Demographics, symptoms, signs, and complication rates were collected for patients with retrocecal appendicitis (RCA) and non-retrocecal appendicitis (NRCA). Results: Four hundred seven patients were included with 12.5% having RCA. Ultrasound was obtained in 92% of patients with RCA versus 82% of NRCA (rate difference: 10%, 95% CI: 2%-19%, P =0.018). In patients who received ultrasound imaging, findings were equivocal or falsely negative in 53% of RCA patients versus 30% of NRCA patients (RD = 24%, 9%-39%; P =0.003). Computed tomography (CT) was obtained in 51% of RCA patients versus 29% of NRCA (RD = 22%, 8%-37%; P =0.003) and was equivocal or falsely negative at similar rates in RCA (12%) and NRCA (13%; P =0.88). Clinically, there were no differences in diarrhea, emesis, location of abdominal pain, or white blood cell counts between RCA and NRCA. Rates of perforation, abscess formation, hospitalization longer than 7 days, and repeat hospitalizations were also similar. Conclusions: Retrocecal appendicitis is a common anatomic variant in children that presents with similar clinical features and outcomes compared with non-retrocecal appendicitis. However, its retrocecal position reduces the diagnostic sensitivity of limited abdominal ultrasound, often necessitating additional imaging with computed tomography. Despite these diagnostic challenges, retrocecal positioning is not associated with a worsened clinical course.

Objectives: The aim of this study was to investigate differences in utilization of diagnostic imaging between the adult and pediatric trauma teams when caring for adolescent trauma patients. Methods: This was a retrospective observational study from 2015 to 2019 comparing pediatric trauma team activations for patients ages 12 to 14 and adult trauma team activations for patients ages 15 to 17 at a single institution verified as both a level I adult and a level I pediatric trauma center. Data were collected from a prospective trauma registry and manual chart review of the electronic medical records. The primary outcome was the frequency of whole body computed tomography (WBCT) and computed tomography (CT) imaging of individual body regions. Results: We identified 191 adult and 100 pediatric trauma team cases, with similar proportions transferred from outside hospitals (40% vs. 43%). Among patients presenting directly from the scene, WBCT use was significantly higher in the adult trauma team group (64% vs. 12%; RR: 5.21; 95% CI: 2.57-10.58), as was CT of all individual body regions. For transferred patients, the adult trauma team more often performed WBCT and individual CT scans, excluding head CT. CT imaging rates before transfer did not differ between groups. No significant differences were observed in injury severity scores, altered mental status, length of stay, or missed injuries. Conclusions: Among adolescents with similar injury severity, the adult trauma team more frequently utilizes WBCT and regional CT than the pediatric team. However, CT use before transfer from outside hospitals without dedicated pediatric trauma teams was similar across age groups.

Abstract Background The pediatric resuscitation and trauma outcome (PRESTO) model was developed to aid comparisons of risk‐adjusted mortality after injury in low‐ and middle‐income countries (LMICs). We sought to validate PRESTO using data from a middle‐income country (MIC) trauma registry and compare its performance to the Pediatric Trauma Score (PTS), Revised Trauma Score, and pediatric age‐adjusted shock index (SIPA). Methods We included children (age < 15 years) admitted to a single trauma center in South Africa from December 2012 to January 2019. We excluded patients missing variables necessary for the PRESTO model—age, systolic blood pressure, pulse, oxygen saturation, neurologic status, and airway support. Trauma scores were assigned retrospectively. PRESTO's previously high‐income country (HIC)‐validated optimal threshold was compared to MIC‐validated threshold using area under the receiver operating characteristic curves (AUROC). Prediction of in‐hospital death using trauma scoring systems was compared using ROC analysis. Results Of 1160 injured children, 988 (85%) had complete data for calculation of PRESTO. Median age was 7 (IQR: 4, 11), and 67% were male. Mortality was 2% ( n = 23). Mean predicted mortality was 0.5% (range 0–25.7%, AUROC 0.93). Using the HIC‐validated threshold, PRESTO had a sensitivity of 26.1% and a specificity of 99.7%. The MIC threshold showed a sensitivity of 82.6% and specificity of 89.4%. The MIC threshold yielded superior discrimination (AUROC 0.86 [CI 0.78, 0.94]) compared to the previously established HIC threshold (0.63 [CI 0.54, 0.72], p < 0.0001). PRESTO showed superior prediction of in‐hospital death compared to PTS and SIPA (all p < 0.01). Conclusion PRESTO can be applied in MIC settings and discriminates between children at risk for in‐hospital death following trauma. Further research should clarify optimal decision thresholds for quality improvement and benchmarking in LMIC settings.

Abstract Background: Operative maneuvers to increase mesenteric length during ileal pouch-anal anastomosis (IPAA) are frequently utilized in adults, but limited data exist on the need for their use in children. Materials and Methods: A retrospective chart review of children (age <18) considered for IPAA creation at two affiliated tertiary referral centers from 2007 to 2017 was conducted, and patient factors, operative details, and 30-day postoperative complications were abstracted. Body mass index (BMI) was normalized to BMI percentile-for-age-and-sex and classified as underweight (BMI <5th percentile), healthy weight (5th ≤ BMI percentile <85th), or overweight/obese (BMI ≥85th percentile). Maneuvers were identified from operative notes. Univariate analysis and multivariable logistic regression were performed to determine independent factors associated with the use of maneuvers. Results: A total of 94 patients underwent attempt at IPAA creation, which was successful in 91 (97%). Fourteen (15%) of 91 patients were classified as overweight or obese. The 3 failures occurred secondary to inability to reach in 3 patients, with specific mention of patients' obesity in 2 and pouch ischemia in 1. Sixty (66%) patients required maneuvers to lengthen the mesentery. Overweight/obese patients required maneuvers more often than nonoverweight/obese patients (93% versus 61%, P = .03). There were no differences in 30-day maximum Clavien-Dindo scores between patients with and without maneuvers performed ( P = .83). Being overweight/obese was an independent risk factor for requiring maneuvers (odds ratio: 9.3, 95% confidence interval: 1.1–82.8) after adjusting for age, sex, height, operative stage, and surgeon. Conclusion: Surgeons should be prepared to perform mesenteric lengthening maneuvers when operating on pediatric patients to ensure minimal tension on the IPAA, and more so when operating on obese children. Whether these maneuvers have an impact on long-term pouch function is undetermined.

Abstract Purpose: Restoration of intestinal continuity by ileal pouch-anal anastomosis (IPAA) following subtotal colectomy may not require a temporary, protective ileostomy. Diversion contributes to patient discomfort, cost, and additional operative risk at the time of subsequent reversal. We compared the outcomes of pediatric patients undergoing modified two-stage to three-stage IPAA after recovering from subtotal colectomy. Methods: We reviewed children (age <18) who underwent IPAA creation for ulcerative or indeterminate colitis from January 1, 2007 to December 31, 2017. Patient characteristics, operative details, 30-day complications, and postoperative length of stay (LOS) were abstracted. Total LOS for the three-stage group included both the IPAA and the ileostomy reversal operations. Univariate comparisons between patients undergoing modified two-stage and three-stage operations were performed. Results: A total of 43 patients underwent IPAA after subtotal colectomy; 32 (74%) underwent a three-stage approach, and 11 (26%) had a modified two-stage approach. Operative approach was laparoscopic in 33 (77%), planned open in 9 (21%), and converted to open in 1 (2%). Single-incision technique was used in 12 of 33 (36%) laparoscopic cases. Modified two-stage procedures had shorter total median LOS (7 days versus 9 days, P = .005). Incidence of postoperative leak, readmission, return to the operating room, and maximum 30-day Clavien–Dindo scores at the time of IPAA creation did not differ between modified two- and three-stage approaches (all P > .05). Conclusion: The modified two-stage approach to IPAA creation resulted in fewer hospital days compared to the three-stage approach. Considering the risks and patient burdens of diversion, further research is needed to assist in decisions regarding protective ileostomy after completion proctectomy with IPAA.

AbstractBackgroundSnake envenomation is associated with major morbidity especially in low‐ and middle‐income countries and may require fasciotomy. We determined patient factors associated with the need for fasciotomy after venomous snake bites in children located in KwaZulu‐Natal, South Africa.MethodsSingle institutional review of historical data (2012–2017) for children (<18 years) sustaining snake envenomation was performed. Clinical data, management, and outcomes were abstracted. Syndromes after snake bite were classified according to Blaylock nomenclature: progressive painful swelling (PPS), progressive weakness (PW), or bleeding (B), as it is difficult to reliably identify the species of snake after a bite. Comparative and multivariable analyses to determine factors associated with fasciotomy were performed.ResultsThere were 72 children; mean age was 7 (±3) years, 59% male. Feet were most commonly affected (n = 27, 38%) followed by legs (n = 18, 25%). Syndromes (according to Blaylock) included PPS (n = 63, 88%), PW (n = 5, 7%), and B (n = 4, 5%). Eighteen patients underwent fasciotomy, and one required above knee amputation. Nine patients received anti‐venom. Few patients (15%) received prophylactic beta‐lactam antibiotics. Hemoglobin < 11 mg/dL, leukocytosis, INR >1.2, and age‐adjusted shock index were associated with fasciotomy. On regression, age‐adjusted shock index and hemoglobin concentration < 11 mg/dL, presentation >24 h after snake bite, and INR >1.2 were independently associated with fasciotomy. Model sensitivity was 0.89 and demonstrated good fit.ConclusionsPatient factors were associated with the fasciotomy. These factors, coupled with clinical examination, may identify those who need early operative intervention. Improving time to treatment and the appropriate administration of anti‐venom will minimize the need for surgery.Level of evidenceIII
