Screening and Prophylaxis for Venous Thromboembolism in Pediatric Surgery: A Systematic Review.

OBJECTIVE: The American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee conducted a systematic review to describe the epidemiology of venous thromboembolism (VTE) in pediatric surgical and trauma patients and develop recommendations for screening and prophylaxis. METHODS: The Medline (Ovid), Embase, Cochrane, and Web of Science databases were queried from January 2000 through December 2021. Search terms addressed the following topics: incidence, ultrasound screening, and mechanical and pharmacologic prophylaxis. The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were followed. Consensus recommendations were derived based on the best available literature. RESULTS: One hundred twenty-four studies were included. The incidence of VTE in pediatric surgical populations is 0.29% (Range = 0.1%-0.48%) and directly correlates with surgery type, transfusion, prolonged anesthesia, malignancy, congenital heart disease, inflammatory bowel disease, infection, and female sex. The incidence of VTE in pediatric trauma populations is 0.25% (Range = 0.1%-0.8%) and directly correlates with injury severity, major surgery, central line placement, body mass index, spinal cord injury, and length-of-stay. Routine ultrasound screening for VTE is not recommended. Consider sequential compression devices in at-risk nonmobile, pediatric surgical patients when an appropriate sized device is available. Consider mechanical prophylaxis alone or with pharmacologic prophylaxis in adolescents >15 y and post-pubertal children <15 y with injury severity scores >25. When utilizing pharmacologic prophylaxis, low molecular weight heparin is superior to unfractionated heparin. CONCLUSIONS: While VTE remains an infrequent complication in children, consideration of mechanical and pharmacologic prophylaxis is appropriate in certain populations. TYPE OF STUDY: Systematic Review of level 2-4 studies. LEVEL OF EVIDENCE: Level 3-4.

Classification and Surgical Management of Anorectal Malformations: A Systematic Review and Evidence-based Guideline From the APSA Outcomes and Evidence-based Practice Committee.

OBJECTIVE: Treatment of neonates with anorectal malformations (ARMs) can be challenging due to variability in anatomic definitions, multiple approaches to surgical management, and heterogeneity of reported outcomes. The purpose of this systematic review is to summarize existing evidence, identify treatment controversies, and provide guidelines for perioperative care. METHODS: The American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee (OEBP) drafted five consensus-based questions regarding management of children with ARMs. These questions were related to categorization of ARMs and optimal methods and timing of surgical management. A comprehensive search strategy was performed, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to perform the systematic review to attempt to answer five questions related to surgical care of ARM. RESULTS: A total of 10,843 publications were reviewed, of which 90 were included in final recommendations, and some publications addressed more than one question (question: 1 n = 6, 2 n = 63, n = 15, 4 n = 44). Studies contained largely heterogenous groups of ARMs, making direct comparison for each subtype challenging and therefore, no specific recommendation for optimal surgical approach based on outcomes can be made. Both loop and divided colostomy may be acceptable methods of fecal diversion for patients with a diagnosis of anorectal malformation, however, loop colostomies have higher rates of prolapse in the literature reviewed. In terms of timing of repair, there did not appear to be significant differences in outcomes between early and late repair groups. Clear and uniform definitions are needed in order to ensure similar populations of patients are compared moving forward. Recommendations are provided based primarily on A-D levels of evidence. CONCLUSIONS: Evidence-based best practices for ARMs are lacking for many aspects of care. Multi-institutional registries have made progress to address some of these gaps. Further prospective and comparative studies are needed to improve care and provide consensus guidelines for this complex patient population.

Management and Outcomes of Pediatric Lymphatic Malformations: A Systematic Review From the APSA Outcomes and Evidence-Based Practice Committee.

BACKGROUND: Significant variation in management strategies for lymphatic malformations (LMs) in children persists. The goal of this systematic review is to summarize outcomes for medical therapy, sclerotherapy, and surgery, and to provide evidence-based recommendations regarding the treatment. METHODS: Three questions regarding LM management were generated according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Publicly available databases were queried to identify articles published from January 1, 1990, to December 31, 2021. A consensus statement of recommendations was generated in response to each question. RESULTS: The initial search identified 9326 abstracts, each reviewed by two authors. A total of 600 abstracts met selection criteria for full manuscript review with 202 subsequently utilized for extraction of data. Medical therapy, such as sirolimus, can be used as an adjunct with percutaneous treatments or surgery, or for extensive LM. Sclerotherapy can achieve partial or complete response in over 90% of patients and is most effective for macrocystic lesions. Depending on the size, extent, and location of the malformation, surgery can be considered. CONCLUSION: Evidence supporting best practices for the safety and effectiveness of management for LMs is currently of moderate quality. Many patients benefit from multi-modal treatment determined by the extent and type of LM. A multidisciplinary approach is recommended to determine the optimal individualized treatment for each patient.

Delphi Consensus on Diagnostic Criteria for LUMBAR Syndrome.

OBJECTIVE: To develop consensus on diagnostic criteria for LUMBAR syndrome, the association of segmental infantile hemangiomas that affect the Lower body with Urogenital anomalies, Ulceration, spinal cord Malformations, Bony defects, Anorectal malformations, Arterial anomalies and/or Renal anomalies. STUDY DESIGN: These diagnostic criteria were developed by an expert multidisciplinary and multi-institutional team based on analysis of peer-reviewed data, followed by electronic-Delphi consensus of a panel of 61 international pediatric specialists. RESULTS: After 2 Delphi rounds, a 92% or higher level of agreement was reached for each Delphi statement. 98% of panelists agreed with the diagnostic criteria, and 100% agreed the criteria would be useful in clinical practice. The diagnosis of LUMBAR requires the presence of a segmental, or patterned, infantile hemangioma of the lumbosacral, sacrococcygeal, or pelvic cutaneous regions plus one additional criterion of the urogenital, spinal, bony, anorectal, arterial, or renal organ systems. CONCLUSIONS: These diagnostic criteria will enhance clinical care by improving screening, detection, and overall awareness of this poorly understood neurocutaneous disorder. The criteria can be utilized by a wide variety of pediatric subspecialists. In addition, formal criteria will improve phenotypic uniformity among LUMBAR syndrome cohorts and a patient registry, allowing investigators to assess clinical features, long-term outcomes, and results of genetic sequencing in a standardized manner. Finally, these criteria will serve as a starting point for prospective studies to establish formal screening and management guidelines.

Hospital Variation in Mortality and Failure to Rescue after Surgery for High-Risk Neonatal Diagnoses.

INTRODUCTION: A large proportion of postoperative mortality after pediatric surgery occurs among neonates with specific high-risk diagnoses. The extent to which there is hospital-level mortality variation among patients with these diagnoses and whether this variation is associated with differences in failure to rescue (FTR) is unclear. METHODS: The Pediatric Health Information System® database (2012-2020) was used to identify patients who underwent surgery for eight high-risk neonatal diagnoses: gastroschisis; volvulus; necrotizing enterocolitis; intestinal atresia; meconium peritonitis; tracheoesophageal fistula; congenital diaphragmatic hernia; and perinatal intestinal perforation. Hospitals were stratified into tertiles of reliability-adjusted inpatient mortality rates (lower than average mortality - tertile 1 [T1]; higher than average mortality - tertile 3 [T3]). Multivariable hierarchical regression was used to evaluate the association between hospital-level, reliability-adjusted mortality and FTR. RESULTS: Overall, 20,838 infants were identified across 48 academic, pediatric hospitals. Adjusted hospital mortality rates ranged from 4.0% (95% CI, 0.0-8.2) to 16.3% (12.2-20.4). Median case volume (range, 80-1,238) and number of NICU beds (range, 24-126) were not significantly different across hospital tertiles. Compared to the hospitals with the lowest postoperative mortality (T1), the odds of FTR were significantly higher in hospitals with the highest (T3) postoperative mortality (odds ratio 1.97 [1.50-2.59]). CONCLUSIONS: Significant variation in neonatal hospital mortality for high-risk diagnoses does not appear to be explained by hospital structural characteristics. Rather, difference in FTR suggests quality improvement interventions targeting early recognition and management of postoperative complications could improve surgical quality and safety for high-risk neonatal care.

Evaluation and Management of Primary Spontaneous Pneumothorax in Adolescents and Young Adults: A Systematic Review From the APSA Outcomes & Evidence-Based Practice Committee.

INTRODUCTION: Controversy exists in the optimal management of adolescent and young adult primary spontaneous pneumothorax. The American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee performed a systematic review of the literature to develop evidence-based recommendations. METHODS: Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL, Elsevier Scopus, and Wiley Cochrane Central Register of Controlled Trials databases were queried for literature related to spontaneous pneumothorax between January 1, 1990, and December 31, 2020, addressing (1) initial management, (2) advanced imaging, (3) timing of surgery, (4) operative technique, (5) management of contralateral side, and (6) management of recurrence. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: Seventy-nine manuscripts were included. Initial management of adolescent and young adult primary spontaneous pneumothorax should be guided by symptoms and can include observation, aspiration, or tube thoracostomy. There is no evidence of benefit for cross-sectional imaging. Patients with ongoing air leak may benefit from early operative intervention within 24-48 h. A video-assisted thoracoscopic surgery (VATS) approach with stapled blebectomy and pleural procedure should be considered. There is no evidence to support prophylactic management of the contralateral side. Recurrence after VATS can be treated with repeat VATS with intensification of pleural treatment. CONCLUSIONS: The management of adolescent and young adult primary spontaneous pneumothorax is varied. Best practices exist to optimize some aspects of care. Further prospective studies are needed to better determine optimal timing of operative intervention, the most effective operation, and management of recurrence after observation, tube thoracostomy, or operative intervention. LEVEL OF EVIDENCE: Level 4. TYPE OF STUDY: Systematic Review of Level 1-4 studies.

No Association of Sirolimus with Wound Complications in Children With Vascular Anomalies.

INTRODUCTION: Sirolimus has demonstrated effectiveness as a treatment option for several types of vascular anomalies; however, it has a potential side effect of delayed surgical wound healing. The purpose of this study was to evaluate the association of sirolimus with postoperative complications in the pediatric vascular anomaly population. METHODS: A retrospective cohort study was performed for children with a vascular anomaly who underwent excision or debulking of the anomaly from 2015 to 2020. Patient demographics, vascular anomaly characteristics, operative variables, sirolimus dosing information, and perioperative outcomes were collected. Univariate analysis was performed to compare outcomes based on the administration of sirolimus. RESULTS: Forty-seven patients with vascular anomalies underwent 57 surgical procedures (36 without perioperative sirolimus, 21 with perioperative sirolimus). The median age at the time of surgery was seven years (IQR 1.7-14.0). The most common anomalies were lymphatic and venolymphatic malformations. Of the patients administered perioperative sirolimus, the median preoperative and postoperative sirolimus levels were comparable (preoperative 6.9 ng/mL (IQR 4.9-10.1), postoperative 6.5 ng/mL (IQR 4.7-9.4)). The rate of postoperative complications (sirolimus 19%, without sirolimus 11%; p = 0.45) and wound complications (sirolimus 14%, without sirolimus 6%; p = 0.26) were comparable between the cohorts. CONCLUSION: Our results suggest sirolimus may not significantly increase perioperative complication rates in pediatric patients undergoing resection of their vascular anomaly. LEVEL OF EVIDENCE: Level III.

An infant with LUMBAR syndrome complicated by severe perineal ulceration managed with diverting colostomy.

Infantile hemangiomas are the most common childhood vascular lesions. LUMBAR syndrome (lower body hemangioma, urogenital abnormalities/ulceration, myelopathy, bony deformities, anorectal malformations/arterial anomalies, and rectal anomalies) warrants special treatment considerations. Here we describe a case of an infant with LUMBAR syndrome who presented with severe perineal ulceration refractory to standard medical therapy and was managed with a temporary diverting sigmoid colostomy. This case demonstrates that adjunctive surgical management can be considered in infants with aggressive perineal wounds refractory to standard medical therapy.

Institutional Management of Abdominal Lymphatic Malformations: Evolution of Treatment Over a Decade.

INTRODUCTION: Abdominal lymphatic malformations (LM) have been historically managed with surgical resection; however, sclerotherapy and sirolimus have emerged as effective therapies. The purpose of our study is to evaluate our institutional change in management and outcomes for abdominal LM over the past decade. METHODS: A retrospective cohort study was performed for all children with an abdominal LM managed at our multidisciplinary Vascular Anomalies Center from 2011 to 2020. Patient demographics, symptoms, treatment, treatment response, and complications were analyzed with descriptive statistics. RESULTS: Twenty-nine patients with abdominal LM were identified with a median age at treatment of 6 y (interquartile range 3-14). A majority of lesions were identified as macrocystic (n = 18, 62%). The most common intervention was surgery alone (n = 14, 48%) followed by sirolimus alone (n = 4, 14%), and sclerotherapy + sirolimus (n = 4, 14%). Five patients were observed due to lack of symptoms at presentation. Prior to 2017, 91% (10/11) of LM were treated with surgery alone. Following 2017, only 31% (4/13) were treated with surgery alone. Sixty-seven percent (16/24) of treated patients had >95% reduction in LM maximum diameter. A majority of patients (23/24) who received treatment had improvement or resolution of symptoms at median 9-mo follow-up. Only three patients had post-treatment complications, including a drain site infection, small bowel obstruction, and an aspiration event. Complications only occurred after sclerotherapy sessions. CONCLUSIONS: Over the study period, our institution has transitioned to initial management of symptomatic abdominal LM with sclerotherapy and/or sirolimus with almost all treated patients having excellent or satisfactory treatment response. Post-treatment complications were rare.

A cross-sectional analysis of compassion fatigue, burnout, and compassion satisfaction in pediatric surgeons in the U.S.

BACKGROUND/PURPOSE: To determine the prevalence of compassion fatigue (CF), burnout (BO), and compassion satisfaction (CS) and identify potential predictors of these phenomena in pediatric surgeons. METHODS: The Compassion Fatigue and Satisfaction Self-Test and a survey of personal/professional characteristics were distributed electronically to American Pediatric Surgical Association members. Linear regression models for CF, BO, and CS as a function of potential risk factors were constructed. RESULTS: The analyzeable study response rate was 25.7%. The prevalence of CF, BO, and CS was 22%, 24% and 22, respectively, which were similar to prevalences previously identified in pediatric subspecialists. Higher CF scores were significantly associated with: higher BO scores; solo practice; compensation; ≥5 operating days/week; current distress about a 'clinical situation'; mental health-care for work-related distress; and history of childhood surgery. Lower CF scores were significantly associated with 'talking with a life partner' about work-related distress. Higher BO scores were significantly associated with: higher CF scores; current distress about 'coworkers'; and 'keeping lawsuits confidential'. Lower BO scores were significantly associated with higher CS scores. CONCLUSIONS: CF, BO, and CS are distinct but highly related entities. Pediatric surgeons experience these phenomena at similar rates to other pediatric subspecialists. Establishing local channels for physician peer support may be particularly impactful.

Supporting recovery after adverse events: An essential component of surgeon well-being.

BACKGROUND: Failure to recover after a medical error is a major contributor to burnout. The degree to which pediatric surgeons experience errors and the barriers and facilitators to successful recovery are largely unknown. METHODS: We conducted a survey of American Pediatric Surgical Association (APSA) members to measure frequency of personal experience with medical errors resulting in significant patient harm, describe coping mechanisms, and explore surgeon satisfaction with institutional support in the wake of an error. RESULTS: We found that 80% of respondents have personally experienced a medical error resulting in significant patient harm or death, and that only about one-quarter were satisfied with the support provided by their institution. Only 11% of surgeons would prefer not to be contacted after an adverse event, and most would want to be contacted by their partners. Barriers to providing and receiving support included lack of knowledge, "shame and blame" culture, and lack of trust in the institution as an ally. CONCLUSIONS: Pediatric surgeons routinely experience intense and stressful clinical scenarios and face challenging paths to recovery after adverse events. Institutions and national societies can play a critical role in creating infrastructure to help surgeons recover, in order to prevent burnout and promote well-being.

Drivers of distress and well-being amongst pediatric surgeons.

INTRODUCTION: Although pediatric surgeons have lower rates of burnout compared to other surgical subspecialists, they still struggle with work-home conflict, depersonalization, and emotional exhaustion. Prior surveys have measured career satisfaction and burnout, but none have identified factors that contribute to physician well-being or provided potential solutions. METHODS: Members of the American Pediatric Surgical Association were surveyed regarding sources of distress and institutional practices intended to promote well-being. Responses were analyzed using content analysis. RESULTS: There was a 31.5% response rate to the survey. The most frequently cited sources of distress were administrative issues (45.2%), work/life balance (42.3%), personal issues (18.8%), and relationships with coworkers (17.9%). In open-ended questions, other sources of distress included poor leadership, loss of autonomy, lack of support and mentorship, and patient complications. Successful wellness strategies included relief from clinical burden, substantive wellness programming, surgeon inclusion in administrative decision making, support after adverse events, appropriate compensation and benefits, and opportunities for career development in research, teaching, and clinical care. CONCLUSION: Pediatric surgeons are affected by multiple sources of distress. Interventions that ameliorate stress in pediatric surgeons were identified and should be considered by local institutions and national organizations to promote well-being. LEVEL OF EVIDENCE: n/a.

Renal Lymphangiectasia in a Pediatric Patient.

Renal lymphatic abnormalities are rare, and the understanding of pathophysiology involving renal lymphatics is limited. Symptoms can include hypertension, hematuria, proteinuria, chyluria, and abdominal and lumbar pain. Imaging techniques specific to the renal lymphatics have not been clarified. We review the intrahospital imaging evaluation/workup and clinical course of a 6-year-old male who presented to our institution with a large perirenal cyst. His presentation presented a diagnostic and management challenge. The cyst was determined to be lymphatic in origin and required multiple interventional radiology and surgical procedures for management.

Development of a multidisciplinary colorectal and pelvic health program: Program implementation and clinical impact.

INTRODUCTION: Pediatric patients with complex colorectal and genitourinary conditions often require coordinated multidisciplinary care; however, this coordinated care can be hard to structure and deliver. The purpose of this paper is to review the development and implementation of a multidisciplinary colorectal and pelvic health program, one year after the program's initiation. METHODS: This is an observational retrospective 1-year study (10/1/2017 to 9/30/2018). In fiscal year (FY) 2018, a multidisciplinary colorectal and pelvic health program was initiated. The program development incorporated bimonthly team meetings, educational conferences, and initiation of three clinics: a complex colorectal and genitourinary reconstruction clinic, a bowel management clinic, and a colonic motility clinic. Conditions treated included complex anorectal and cloacal malformations, Hirschsprung disease, and idiopathic constipation. The fiscal year was selected to provide comparative administrative data after program implementation. RESULTS: During the study period, 121 patients underwent comprehensive collaborative evaluation of which 58 (47%) were new to the institution compared to 12 (19%) new patients in the previous year (p < 0.001). In FY 2018, there were 130 procedures performed and 512 collaborative visits with an average of 47 visits per month. This was a 3.4-fold increase in visits compared to FY2017 (171 visits). Of the new patients, 60% (35/58), traveled a median of 181 miles, representing 33 statewide counties, and 4 states compared to a median of 93 miles in the previous fiscal year (p = 0.004). CONCLUSION: The development of a colorectal and pelvic health program is feasible and requires a collaborative approach, necessitating multiple service lines within an institution. Program creation and implementation can result in rapid institutional clinical growth by filling a local and regional need through coordinated multidisciplinary care. LEVEL OF EVIDENCE: IV.

Management of ovarian lesions diagnosed during infancy.

PURPOSE: Prior studies of infant ovarian cysts have recommended intervention for those larger than 4 cm. We reviewed the natural history and features of those managed operatively versus nonoperatively. METHODS: A retrospective study was performed of ovarian lesions in children <1 year-old from 2000 to 2014. RESULTS: Forty patients were identified. Twenty-eight (70%) underwent operative management, while 12 (30%) were managed conservatively, including one undergoing aspiration. The mean age at surgery was 125 days. All but one patient (96%) had evidence of antenatal torsion intraoperatively or on final pathology. All resected lesions were benign. Ultrasound findings more common in those undergoing surgery included intracystic debris (p < 0.001), fluid-fluid or fluid-debris levels (p = 0.002), absence of Doppler flow (p = 0.014), solid components (p = 0.04), and calcifications (p = 0.001). Cysts managed nonoperatively had an average diameter of 2.5 cm, compared to 5.1 cm in the operative group (p < 0.001). Three of the lesions managed nonoperatively had a diameter greater than 3.5 cm (mean 5.1 cm) and were followed for an average of 153 days until resolution. CONCLUSIONS: The majority of infant ovarian lesions were excised, although none were malignant. Aspiration or observation of larger cysts was feasible and safe. Ovarian cysts in this age group should be considered for nonoperative management and closely followed. LEVEL OF EVIDENCE: IIC.

Long-term outcomes for children with very early-onset colitis: Implications for surgical management.

PURPOSE: The timing of J-pouch surgery following colectomy for children with very early-onset colitis is controversial, with some advocating early reconstruction and others delaying reconstruction because of fear that the colitis may be owing to Crohn's disease (CD). We sought to determine the long-term incidence of CD in this population and whether there may be clinical features that predict the risk of CD. METHODS: Children with noninfectious colitis diagnosed prior to age 10, who underwent subtotal colectomy and ileostomy from 2000 to 2015, were reviewed. RESULTS: Twenty-five children were identified. Median age at presentation was 5.4years. Four were initially diagnosed with CD (16%), 14 with ulcerative colitis (UC) (56%), and 7 with inflammatory bowel disease unclassified (IBD-U) (28%). Eight eventually had pouch surgery. Five of the children with an initial diagnosis of UC or IBD-U developed findings that changed the diagnosis to CD at a median age of 13.4 (range 10.3 to 16.7) years. None had any indicators of CD at the initial presentation. CONCLUSIONS: Approximately one quarter of patients with very early-onset colitis originally diagnosed as UC or IBD-U had a reclassification in diagnosis to CD over time. J-pouch reconstruction should be delayed until adolescence in children with very early-onset colitis. LEVEL OF EVIDENCE: 2C.

Comparing oncologic outcomes after minimally invasive and open surgery for pediatric neuroblastoma and Wilms tumor.

BACKGROUND: Minimally invasive surgery (MIS) has been widely adopted for common operations in pediatric surgery; however, its role in childhood tumors is limited by concerns about oncologic outcomes. We compared open and MIS approaches for pediatric neuroblastoma and Wilms tumor (WT) using a national database. METHODS: The National Cancer Data Base from 2010 to 2012 was queried for cases of neuroblastoma and WT in children ≤21 years old. Children were classified as receiving open or MIS surgery for definitive resection, with clinical outcomes compared using a propensity matching methodology (two open:one MIS). RESULTS: For children with neuroblastoma, 17% (98 of 579) underwent MIS, while only 5% of children with WT (35 of 695) had an MIS approach for tumor resection. After propensity matching, there was no difference between open and MIS surgery for either tumor for 30-day mortality, readmissions, surgical margin status, and 1- and 3-year survival. However, in both tumors, open surgery more often evaluated lymph nodes and had larger lymph node harvest. CONCLUSION: Our retrospective review suggests that the use of MIS appears to be a safe method of oncologic resection for select children with neuroblastoma and WT. Further research should clarify which children are the optimal candidates for this approach.

Clinical Acuity Shorthand System: a standardized classification tool to facilitate handoffs.

BACKGROUND: The handoff of medical information from one provider to another can be inefficient and error prone, potentially undermining patient safety. Although several tools for structuring handoffs exist, none provide a brief, standardized framework for ensuring that patient acuity is efficiently and reliably communicated. We aim to introduce and perform initial testing of the Clinical Acuity Shorthand System (CLASS) (Copyright 2015, Duke University. All rights reserved.) for surgery, a patient classification tool intended to facilitate efficient communication of key patient information during handoffs. MATERIALS AND METHODS: Surgical trainees at a single center were asked to perform an exercise involving application of CLASS to 10 theoretical patient scenarios and to then complete a brief survey. Responses were scored based on similarity to target answers. Performance was evaluated overall and between groups of trainees. Time required to complete the exercise was also determined and perceived utility of the system was assessed based on survey responses. RESULTS: The study task was completed by 17 participants. Mean time to task completion was 10.3 ± 8.4 min. Accuracy was not decreased, and was in fact superior, in junior trainees. Most respondents indicated that such a system would be feasible and could prevent medical errors. CONCLUSIONS: CLASS is a novel system that can be learned quickly and implemented readily by trainees and can be used to convey patient information concisely and with acceptable fidelity regardless of level of training. Further study examining application of this system on clinical surgical services is warranted.

Current use and outcomes of helicopter transport in pediatric trauma: a review of 18,291 transports.

PURPOSE: The role of helicopter emergency medical services (HEMS) in pediatric trauma remains controversial. We examined its use in pediatric trauma and its effectiveness in children with moderate/severe injuries. METHODS: All blunt/penetrating trauma patients ≤18years old in the National Trauma Data Bank were evaluated for use of HEMS and in-hospital mortality. In a comparative effectiveness study, only patients treated at level I/II pediatric centers with injury severity score (ISS)≥9 were included. RESULTS: Of 127,489 included patients, 18,291 (14%) arrived via HEMS, compared to 56% by ground ambulance and 29% by private vehicle/walk-in. HEMS patients had more severe injuries (ISS≥25; 28% vs. 14%) and altered mental status (GCS≤8; 29% vs. 11%), but also contained many patients with only minor injuries or no major physiologic derangements. In unadjusted analysis, HEMS was associated with increased mortality (OR: 1.6; 95% CI: 1.4-1.7). However, it had decreased mortality by regression (0.5; 0.4-0.6) and propensity analysis (0.7; 0.6-0.8) to adjust for confounders. CONCLUSION: We found multiple indicators for overuse of HEMS, with nearly 40% of children having only minor injuries. In moderate/severe injuries, HEMS is associated with decreased mortality, potentially saving one life for every 47 flights. Research is needed to determine appropriate criteria for helicopter triage.

Influence of weight at enterostomy reversal on surgical outcomes in infants after emergent neonatal stoma creation.

PURPOSE: Neonates after emergent enterostomy creation frequently require reversal at low weight because of complications including cholestasis, dehydration, dumping, failure to thrive, and failure to achieve enteral independence. We investigated whether stoma reversal at low weight (< 2.5kg) is associated with poor surgical outcomes. METHODS: Patients who underwent enterostomy reversal from 2005 to 2013 at less than 6months old were identified in our institutional database. Only patients who underwent emergent enterostomy creation (i.e. for necrotizing enterocolitis or spontaneous perforation) were included. Demographics, disease process, comorbidities, stoma type, reversal indication, operative details, and complications were examined. Patients were categorized by weight at reversal of less than 2kg, 2.01-2.5kg, 2.51-3.5kg, and greater than 3.5kg. Data were analyzed using univariable and multivariable regression with significance level of p<0.05. The primary outcome examined was major morbidity, defined as the presence of anastomotic leak, obstruction, hernia, EC fistula, perforation, wound infection, sepsis, or death. RESULTS: Eighty-nine patients met inclusion criteria. Demographics (sex, ethnicity, surgical disease process, reversal indication, and ASA score) were similar. The lowest weight group had lower gestational age (p<0.001) and birth weight (p=0.005), and contained a higher proportion of jejunostomies to ileostomies (p=0.013). On univariable analysis, only incisional hernia was significantly different as a complication between weight groups. On multivariable analysis controlling for gestational age and ASA, there was no significant difference in odds of major operative morbidity between groups. CONCLUSIONS: Enterostomy reversal at lower weight may not be associated with increased risk of perioperative complications. Early stoma reversal may be acceptable when required for progression of neonatal care. LEVEL OF EVIDENCE: Level III, Treatment Study (Retrospective comparative study).
