Radiographic assessment of traction-induced esophageal growth and traction-related complications of the Foker process for treatment of long-gap esophageal atresia.

BACKGROUND: Radiographic assessment of esophageal growth in long-gap esophageal atresia while on traction and associated traction-related complications have not been described. OBJECTIVE: To demonstrate how chest radiography can estimate esophageal position while on traction and to evaluate radiography's utility in diagnosing certain traction system complications. MATERIALS AND METHODS: In this retrospective evaluation of portable chest radiographs obtained in infants with long-gap esophageal atresia who underwent the Foker process between 2014 and 2020, we assessed distances between the opposing trailing clips (esophageal gap) and the leading and trailing clips for each esophageal segment on serial radiographs. Growth during traction was estimated using longitudinal random-effects regression analysis to account for multiple chest radiograph measurements from the same child. RESULTS: Forty-three infants (25 male) had a median esophageal gap of 4.5 cm. Median traction time was 14 days. Median daily radiographic esophageal growth rate for both segments was 2.2 mm and median cumulative growth was 23.6 mm. Traction-related complications occurred in 13 (30%) children with median time of 8 days from traction initiation. Daily change >12% in leading-to trailing clip distance demonstrated 86% sensitivity and 92% specificity for indicating traction-related complications (area under the curve [AUC] 0.853). Cumulative change >30% in leading- to trailing-clip distance during traction was 85% sensitive and 85% specific for indicating traction complications (AUC 0.874). CONCLUSION: Portable chest radiograph measurements can serve as a quantitative surrogate for esophageal segment position in long-gap esophageal atresia. An increase of >12% between two sequential chest radiographs or >30% increase over the traction period in leading- to trailing-clip distance is highly associated with traction system complications.

A survey of the global impact of COVID-19 on the practice of pediatric anesthesia: A study from the pediatric anesthesia COVID-19 Collaborative Group.

BACKGROUND: Pediatric anesthesiology has been greatly impacted by COVID-19 in the delivery of care to patients and to the individual providers. With this study, we sought to survey pediatric centers and highlight the variations in care related to perioperative medicine during the COVID-19 pandemic, including the availability of protective equipment, the practice of pediatric anesthesia, and economic impact. AIM: The aim of the survey was to determine how COVID-19 directly impacted pediatric anesthesia practices during the study period. METHODS: A survey concerning four major domains (testing, safety, clinical management/policy, economics) was developed. It was pilot tested for clarity and content by members of the Pediatric Anesthesia COVID-19 Collaborative. The survey was administered by email to all Pediatric Anesthesia COVID-19 Collaborative members on September 1, 2020. Respondents had six weeks to complete the survey and were instructed to answer the questions based on their institution's practice during September 1 - October 13, 2020. RESULTS: Sixty-three institutions (100% response rate) participated in the COVID-19 Pediatric Anesthesia Survey. Forty-one hospitals (65%) were from the United States, and 35% included other countries. N95 masks were available to anesthesia teams at 91% of institutions (n = 57) (95% CI: 80%-96%). COVID-19 testing criteria of anesthesia staff and guidelines to return to work varied by institution. Structured simulation training aimed at improving COVID-19 safety and patient care occurred at 62% of institutions (n = 39). Pediatric anesthesiologists were economically affected by a reduction in their employer benefits and restriction of travel due to employer imposed quarantine regulations. CONCLUSION: Our data indicate that the COVID-19 pandemic has impacted the testing, safety, clinical management, and economics of pediatric anesthesia practice. Further investigation into the long-term consequences for the specialty is indicated.

Response assessment in paediatric low-grade glioma: recommendations from the Response Assessment in Pediatric Neuro-Oncology (RAPNO) working group.

Paediatric low-grade gliomas (also known as pLGG) are the most common type of CNS tumours in children. In general, paediatric low-grade gliomas show clinical and biological features that are distinct from adult low-grade gliomas, and the developing paediatric brain is more susceptible to toxic late effects of the tumour and its treatment. Therefore, response assessment in children requires additional considerations compared with the adult Response Assessment in Neuro-Oncology criteria. There are no standardised response criteria in paediatric clinical trials, which makes it more difficult to compare responses across studies. The Response Assessment in Pediatric Neuro-Oncology working group, consisting of an international panel of paediatric and adult neuro-oncologists, clinicians, radiologists, radiation oncologists, and neurosurgeons, was established to address issues and unique challenges in assessing response in children with CNS tumours. We established a subcommittee to develop consensus recommendations for response assessment in paediatric low-grade gliomas. Final recommendations were based on literature review, current practice, and expert opinion of working group members. Consensus recommendations include imaging response assessments, with additional guidelines for visual functional outcomes in patients with optic pathway tumours. As with previous consensus recommendations, these recommendations will need to be validated in prospective clinical trials.

Patient and physician discordance of global disease assessment in juvenile dermatomyositis: findings from the Childhood Arthritis & Rheumatology Research Alliance Legacy Registry.

BACKGROUND: Global disease activity scores (gVAS) capture patient or family (PF) and physician (MD) assessments of disease. This study sought to measure discordance between PF and MD global activity scores in juvenile dermatomyositis (JDM), and determine factors associated with discordance. METHODS: Patients with JDM were included from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry (N = 563). PF and MD gVAS were assessed for discordance, defined as a ≥ 2-point difference. Factors associated with discordant gVAS were compared in univariate analysis. Multivariable regression analysis was used to identify predictors of discordance. RESULTS: Almost 40% (N = 219) of PF and MD gVAS were discordant. Among discordant scores, 68% of PF rated gVAS ≥2-points above MD, which was associated with calcinosis and lower quality of life and functional scores (p < 0.01). MD gVAS rated ≥2-points above PF in 32%, which was associated with abnormal laboratory results, weakness, arthritis, rash and other skin changes, and current intravenous steroid treatment (p < 0.01). In multivariate analysis, predictors for higher PF rating included calcinosis, lower quality of life and functional scores, while predictors for higher MD rating included rash, calcinosis, nailfold capillaroscopy changes, and current intravenous steroid treatment. CONCLUSIONS: Discordance between PF and MD gVAS was common in this JDM cohort. Overall, higher PF rating was associated with poorer patient reported outcome (PRO) scores, while higher MD rating was associated with poorer objective measures. This suggests PF and MD assessments of gVAS may be measuring different aspects of disease, highlighting the importance of integrating PROs into clinical practice and research.

Symptomatic Tetralogy of Fallot in Young Infants: Primary Repair or Shunt-Pediatric Health Information System Database Analysis.

BACKGROUND: Compare the early outcomes and hospital charges of early primary repair and systemic-to-pulmonary artery shunt for neonates and young infants (≤90 days of age) with tetralogy of Fallot using data from the Pediatric Health Information System database. METHODS: The Pediatric Health Information System database was queried for patients <90 days of age with primary diagnosis of tetralogy of Fallot who underwent nonelective surgical repair or palliation between January 2008 and December 2014. The initial cohort of 821 patients (group 1 early primary repair, N = 554; group 2 systemic-to-pulmonary artery shunt, N = 267) was propensity score matched (248 patients in each group) to account for baseline imbalances in age and prostaglandin use. RESULTS: Comparison of unmatched groups revealed younger age and higher incidence of extracardiac anomalies ( P = .02) and prematurity ( P = .04) in group 2. Mortality was comparable between the groups (group 1: 20 [4%] of 554 vs group 2: 11 [4%] of 267, P = .74). Irrespective of the type of procedure, prematurity (odds ratio [OR] = 3.3, 95% confidence interval [CI]: 1.5-7.4) and extracardiac anomalies (OR = 2.5, 95% CI: 1.2-5.3) were independent risk factors for mortality. Propensity score-matched analysis revealed no significant differences in patient mortality ( P = 1), duration of ventilation ( P = .64), hospital length of stay ( P = .69), or hospital charges ( P = .08) between the two groups. CONCLUSION: Outcomes and hospital charges associated with nonelective early primary repair are comparable to systemic-to-pulmonary artery shunt in symptomatic patients <90 days old with tetralogy of Fallot.

Medication errors in a pediatric anesthesia setting: Incidence, etiologies, and error reduction strategies.

STUDY OBJECTIVE: The objective of the study was to: a) characterize the frequency, type, and outcome of anesthetic medication errors spanning an 8.5-year period, b) describe the targeted error reduction strategies and c) measure the effects, if any, of a focused, continuous, multifaceted Medication Safety Program. DESIGN: Retrospective analysis. SETTING: All anesthetizing locations (57). PATIENTS: All anesthesia patients at all Boston Children's Hospital anesthetizing locations from January 2008 to June 2016 were included. INTERVENTIONS: Medication libraries, zero-tolerance philosophy, independent verification, trainee education, standardized dosing; retrospective study. MEASUREMENTS: Number and type of medication errors. MAIN RESULTS: 105 medication errors were identified among the 287,908 cases evaluated during the study period. Incorrect dose (55%) and incorrect medication (28%) were the most frequently observed errors. Beginning within 3 years of the implementation of the 2009 Medication Safety Program, the incidence declined to an average of 3.0 per 10,000 cases in the years from 2010 to 2016 (57% reduction) and declined to an average of only 2.2 per 10,000 cases since 2012 (69% reduction). Logistic regression indicated a 13% reduction per year in the odds of a medication error over the time period (odds ratio = 0.87, 95% CI: 0.79-0.95, P = 0.004). CONCLUSIONS: Although medication errors persisted, there was a statistically significant reduction in errors during the study period. Formalized Medication Safety Programs should be adopted by other departments and institutions; these Programs could help prevent medication errors and decrease their overall incidence.

Response assessment in medulloblastoma and leptomeningeal seeding tumors: recommendations from the Response Assessment in Pediatric Neuro-Oncology committee.

Lack of standard response criteria in clinical trials for medulloblastoma and other seeding tumors complicates assessment of therapeutic efficacy and comparisons across studies. An international working group was established to develop consensus recommendations for response assessment. The aim is that these recommendations be prospectively evaluated in clinical trials, with the goal of achieving more reliable risk stratification and uniformity across clinical trials. Current practices and literature review were performed to identify major confounding issues and justify subsequently developed recommendations; in areas lacking scientific investigations, recommendations were based on experience of committee members and consensus was reached after discussion. Recommendations apply to both adult and pediatric patients with medulloblastoma and other seeding tumors. Response should be assessed using MR imaging (brain and spine), CSF cytology, and neurologic examination. Clinical imaging standards with minimum mandatory sequence acquisition that optimizes detection of leptomeningeal metastases are defined. We recommend central review prior to inclusion in treatment cohorts to ensure appropriate risk stratification and cohort inclusion. Consensus recommendations and response definitions for patients with medulloblastomas and other seeding tumors have been established; as with other Response Assessment in Neuro-Oncology recommendations, these need to now be prospectively validated in clinical trials.

Quality Assessment of Meta-analyses Published in Leading Anesthesiology Journals From 2005 to 2014.

Meta-analysis, when preceded by a systematic review, is considered the "gold standard" in data aggregation; however, the quality of meta-analyses is often questionable, leading to uncertainty about the accuracy of results. In this study, we evaluate the quality of meta-analyses published in 5 leading anesthesiology journals from 2005 to 2014. A total of 220 meta-analyses published in Anesthesiology, Pain, British Journal of Anaesthesia, Anaesthesia, or Anesthesia & Analgesia were identified for inclusion. The quality of each meta-analysis was determined using the Revised Assessment of Multiple Systematic Reviews (R-AMSTAR). R-AMSTAR rated 11 questions related to systematic reviews and meta-analyses on a scale of 1-4, with 4 representing the highest quality. Overall meta-analyses quality was evaluated using a Spearmen regression analysis and found to positively correlate with time (rs = 0.24, P < .001). Similarly, a temporal association was found for conflict of interest (rs = 0.51, P < .001) and comprised a list of included and excluded studies (rs = 0.32, P < .001). In conclusion, the quality of meta-analyses published in leading anesthesiology journals has increased over the last decade. Furthermore, assessing the scientific quality of included studies in meta-analyses (P = .60) and using this assessment to formulate conclusions and/or recommendations (P = .67) remains relatively low (median R-AMSTAR: 2, interquartile range [IQR]: 2-3]; median R-AMSTAR: 2, IQR: 1-2, respectively).

National Survey of US academic anesthesiology chairs on clinician wellness.

STUDY OBJECTIVE: The prevalence of anesthesiology department wellness programs is unknown. A database of wellness programs is needed as a resource for departments attempting to respond to the Accreditation Council for Graduate Medical Education Anesthesiology Milestones Project. The purpose of this study was to survey academic anesthesiology chairs on wellness issues, characterize initiatives, and establish wellness contacts for a Wellness Initiative Database (WID). DESIGN: An Internet-based survey instrument was distributed to academic anesthesiology department chairs in the United States. SETTING: On-line. PATIENTS: None. INTERVENTIONS: None. MEASUREMENTS: Analysis for continuous variables used standard means, modes, and averages for individual responses; 95% confidence intervals for proportions were calculated by Wilson's method. MAIN RESULTS: Seventy-five (56.4%) responses (of a potential 133 programs) were obtained. Forty-one (of 71 responders; 57.8%) expressed interest in participating in a WID, and 33 (44%) provided contact information. Most (74.7%) had recently referred staff for counseling or wellness resources, yet many (79.5% and 67.1%, respectively) had never surveyed their department's interest in wellness resources. Thirty-four percent had a wellness resources repository. Of 22 wellness topics, 8 garnered >60% strong interest from respondents: Addiction Counseling, Sleep Hygiene, Peer Support Program, Stress Management, Conflict Management, Burnout Counseling, Time Management, and Dealing with Adverse Events Training. There was a statistically significant difference in interest between those willing to participate or not in the WID across most topics but no significant difference based on need for recent staff referral. CONCLUSIONS: The majority of chairs needed to recently refer a department member to wellness resources or counseling. Most were interested in participating in a WID, whereas a minority had gauged staff interest in wellness topics or had a wellness resource repository. Highest interest was in topics most related to function as an anesthesiologist. Those willing to participate in the database had statistically significant differences in interest across most wellness topics.

Beyond perforation: Influence of peritoneal contamination on clinical severity and resource utilization in children with perforated appendicitis.

PURPOSE: The purpose of the study was to explore the relationship between the degree of peritoneal contamination and postoperative resource utilization in children with complicated appendicitis. METHODS: Intraoperative findings were collected prospectively at a single children's hospital from 2012 to 2014. The degree of peritoneal contamination was categorized as either "localized" (confined to the right lower quadrant and pelvis) or "extensive" (extending to the liver). Imaging utilization, postoperative length of stay (pLOS), hospital cost, and readmission rates were compared between groups. RESULTS: Of 88 patients with complicated appendicitis, 38% had extensive contamination. Preoperative characteristics were similar between groups. Patients with extensive contamination had higher rates of postoperative imaging (58.8% vs 27.7%, P<0.01), a 50% longer median pLOS (6days [IQR 4-9] vs 4days [IQR 2-5], P=0.003), a 30% higher median hospital cost ($17,663 [IQR $12,564-$23,697] vs $13,516 [IQR $10,546-$16,686], P=0.004), and a nearly four-fold higher readmission rate (20.6% vs 5.6%, P=0.04) compared to children with localized contamination. CONCLUSION: Extensive peritoneal contamination is associated with significantly higher resource utilization compared to localized contamination in children with complicated appendicitis. These findings may have important severity-adjustment implications for reimbursement and readmission rate reporting for hospitals that serve populations where late presentation is common.

Differences in health-related quality of life and caregiver burden after hip and spine surgery in non-ambulatory children with severe cerebral palsy.

AIM: The aim of this study was to evaluate changes in caregivers' perceptions of health-related quality of life (HRQOL) and caregiver impact in children with severe, non-ambulatory cerebral palsy after orthopedic surgery to correct hip or spine deformities. METHOD: A prospective longitudinal cohort study (n=44) design was used to measure changes before and after surgery. Caregivers completed the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD) and the Assessment of Caregiver Experience with Neuromuscular Disease (ACEND). Data collection was between February 2011 and February 2014. Caregivers were included if their child was 3 to 25 years old, had cerebral palsy in Gross Motor Function Classification System levels IV and V, and was scheduled for orthopedic surgery. Analysis of variance with repeated measures was used to assess changes before and at four time points after surgery. RESULTS: Forty-four caregivers participated. Caregivers' perceptions of their child's HRQOL demonstrated an improvement from baseline to 12 months (p<0.001). Patients who had spine surgery demonstrated a steady improvement over time, whereas patients who had hip surgery had a decrease at 6 weeks followed by steady improvement. Improvements were noted in five of six of the CPCHILD domains, with no changes in the quality of life domain. No changes were noted in any of the ACEND domains. INTERPRETATION: Caregivers report an improvement in a variety of domains of HRQOL 1 year after orthopedic surgery.

Defining Avoidable and Unavoidable Complications in Spine Surgery: A Survey-based Study of Spine Fellowship Directors.

STUDY DESIGN: A cross-sectional survey of orthopedic spine surgery fellowship directors in the United States. OBJECTIVE: The aim of this study was to investigate whether consensus exists with respect to spine-related adverse events and certain hospital-acquired conditions (HACs) or "never events." SUMMARY OF BACKGROUND DATA: As part of a broad effort to improve health care outcomes, providers are no longer reimbursed for HACs, which are deemed avoidable. Although some HACs are unquestionably preventable with proper quality control measures, research suggests that even scrupulous adherence to evidence-based guidelines cannot eliminate others. METHODS: Surveys were distributed via email and post. Participants rated 27 HACs and selected spine-specific events on an ordinal scale. Interobserver reliability was assessed among all 46 spine directors (respondents) using the intraclass correlation coefficient (ICC), based on a two-way random effects model, assuming that the participants were a representative population sample of spine surgeons. Multivariable linear regression analyses were performed on each of the 27 complications to identify potential demographic factors that could be associated with variation among respondents in their ratings of "avoidable" to "unavoidable." RESULTS: Forty-six fellowship directors responded, of whom 98% were orthopedic spine surgeons. The majority (80.4%) of respondents had greater than 10 years' experience as a spine surgeon, and 66.7% had an annual surgical volume >201 cases. The multivariable linear regression analyses found that demographic factors were not predictive of the directors' ratings. The complications thought to be completely avoidable (median scores 1) included "Incompatible blood," "Retained foreign object," and "Wrong level surgery." The HAC considered least avoidable was "Site infection with risk factors" (median score 8). Among 17 spine-specific complications, "L4-L5 disc re-herniation within 3 months" (median score 9) was considered least avoidable. CONCLUSION: This survey suggests that orthopedic spine surgeons consider most "never events" neither avoidable nor unavoidable. There is strong consensus only about the HACs resulting from obvious medical error. LEVEL OF EVIDENCE: 4.

Ethnic and gender diversity in hand surgery trainees.

PURPOSE: To evaluate whether the lack of diversity in plastic and orthopedic surgery persists into hand surgery through assessment of trainee demographics. METHODS: Demographic data were obtained from compilations on graduate medical education by the Journal of the American Medical Association. Ethnic diversity was assessed using the proportions of minority trainees. We analyzed the trends in ethnic diversity in hand, orthopedic, and plastic surgery from 1995 to 2012 by evaluating changes in proportions of African American, Hispanic, and Asian trainees. In addition, we compared the proportions of minority trainees in various surgical specialties during 2009 to 2012. Trends in gender diversity were similarly analyzed using the proportions of female trainees. RESULTS: During 1995 to 2012, the proportions of minority and female trainees increased significantly in the fields of orthopedic, plastic, and hand surgery. To assess the current state of diversity in various specialties, we compared minority and female population proportions using pooled 2009 to 2012 data. The percentage of non-Caucasian trainees in hand surgery was significantly higher than that in orthopedic sports medicine and orthopedic surgery and significantly lower than in general surgery. The percentage of female trainees in hand surgery was significantly higher than that in orthopedic sports medicine and orthopedic surgery and significantly lower than in plastic and general surgery. CONCLUSIONS: Ethnic and gender diversity in hand surgery increased significantly between 1995 and 2012. Women constitute a fifth of hand surgery trainees. Efforts to increase diversity should be further pursued using proven strategies and innovating new ones. CLINICAL RELEVANCE: Diversity in the medical field has shown to be a beneficial factor in many aspects including research productivity and patient care. Understanding how the field of hand surgery has changed with regard to the diversity of its trainees may aid in providing more equitable and effective health care.

Impact of visors on eye and orbital injuries in the National Hockey League.

OBJECTIVE: Eye and orbital injuries are a significant risk to professional hockey league players and have resulted in career-ending injuries. The goal of this study was to determine the incidence, value lost, mechanism, and effect of visors on eye and orbital injuries over the last 10 National Hockey League (NHL) seasons: 2002-2003 to 2012-2013. DESIGN: Retrospective case-control study. PARTICIPANTS: Participants were 8741 NHL players who had played at least 1 game during the last 10 seasons. METHODS: Using The Sports Network (TSN), ProSportsTransactions, and the Sporting News Hockey Register, NHL players were searched to identify eye and orbital injuries. The mechanism of injury was obtained from media reports and direct observation from online videos. The number of players wearing visors each year was obtained from The Hockey News annual visor survey. RESULTS: A total of 149 eye or orbital injuries over the last 10 seasons resulted in an overall incidence of 2.48 per 10 000 athlete exposures. A total of 1120 missed games led to a lost financial value of more than $33 million. Visor use among players grew from 32% in 2002-2003 to 73% in 2012-2013, and there was a significantly increased risk for having an eye or orbital injury when a visor was not worn (OR 4.23, 95% CI 2.84-6.30). Most injuries were a result of being hit by a deflected or direct puck (37%) followed by being struck by a high stick (28%). Players who did not wear a visor were found to be involved in more fights, hits, and penalty minutes (p < 0.001). CONCLUSIONS: Eye and orbital injuries are mostly accidental in nature and represent a significant risk and cost to the NHL and its players. Eye and orbital injuries are significantly more likely in players who do not wear visors.

Comparison of acquisition costs of surgical supplies in different health care systems for cataract and glaucoma procedures.

PURPOSE: To determine cost identification and acquisition cost comparison of surgical supplies for performing cataract and glaucoma procedures. METHODS: This is a nonrandomized comparative and cross-sectional study. Six health care systems [state-run charity hospital, a private university hospital, 2 ambulatory surgical centers (ASCs), and 2 Veterans Affairs Medical Centers] participated in the study. A list of input prices for disposable surgical items necessary for phacoemulsification with intraocular lens and for trabeculectomy with mitomycin-C (MMC), Ex-PRESS shunt placement, and Ahmed glaucoma valve (AGV) with scleral patch graft was administered to 6 facilities. The total acquisition costs for each surgery at each facility was calculated as the sum of necessary items' costs. All costs are expressed in 2011 US dollars. Total acquisition costs for phacoemulsification/intraocular lens, trabeculectomy with MMC, Ex-PRESS shunt and AGV with scleral patch graft implantation in different health care settings were the main outcome measures. RESULTS: The state-run hospital had the highest overall cost of disposable items for both cataract surgery ($648) and trabeculectomy with MMC ($339), whereas the Veterans Affairs Medical Centers had the lowest acquisition costs for cataract ($386) and the ASC ($96) for trabeculectomy. The ASC system had the lowest cost for both Ex-PRESS shunt ($707) and AGV ($865), whereas the University ($1352 for the Ex-PRESS) and the state ($1338 for AGV) had the highest cost. Average difference between total disposable item acquisition costs and Medicare payment after different surgeries per case is as follows: $544.29 for cataract surgery, $1834.50 for trabeculectomy, $763.30 for Ex-PRESS shunt, and $1315.00 for the AGV surgery. CONCLUSIONS: The ASC system had the lowest acquisition cost for disposable items for both cataract and glaucoma surgeries, whereas the university hospital and the state hospital carried the highest costs on an average. Among the 3 glaucoma procedures compared, trabeculectomy has the lowest acquisition costs for disposable items.

Brasfield and Wisconsin scoring systems have equal value as outcome assessment tools of cystic fibrosis lung disease.

BACKGROUND: Several imaging-based scoring systems have been used as outcome measures in assessing the severity of cystic fibrosis (CF) lung disease. It has been shown that chest radiography performs equally to computed tomography (CT). There is the opinion that of the two most commonly used chest radiograph (CXR) systems, the Brasfield system is less sensitive and reliable than the Wisconsin system. OBJECTIVE: This report assesses the reproducibility and reliability of the two systems. MATERIALS AND METHODS: Thirty patients with CXRs during a 5-year period were randomly selected. One hundred eighty-two studies had data for all CXRs and pulmonary function tests (PFTs), Forced Expiratory Volume in One Second (FEV-1) and Forced Vital Capacity (FVC). PFT values closest to the date of each CXR were recorded. Four radiologists scored each image twice by both the Brasfield and Wisconsin systems. Intra- and inter-rater reliability, correlation with PFTs and direct correlation of the two systems were calculated. RESULTS: Intra-rater agreement: r = 0.86-0.99 Brasfield, r = 0.78-0.96 Wisconsin. Inter-rater agreement: 0.76-0.90 Brasfield, r = 0.74-0.97 Wisconsin. Brasfield vs. FEV-1: r = 0.55, vs. FVC r = 0.61. Wisconsin vs. FEV-1: r = 0.57, vs. FVC r = 0.66. Correlation of the two systems: r = 0.86 (all P < 0.001). CONCLUSION: The Brasfield and Wisconsin systems performed very similarly providing equally reproducible, robust and reliable measures.

Challenges with defining response to antitumor agents in pediatric neuro-oncology: a report from the response assessment in pediatric neuro-oncology (RAPNO) working group.

Criteria for new drug approval include demonstration of efficacy. In neuro-oncology, this is determined radiographically utilizing tumor measurements on MRI scans. Limitations of this method have been identified where drug activity is not reflected in decreased tumor size. The RANO (Response Assessment in Neuro-Oncology) working group was established to address limitations in defining endpoints for clinical trials in adult neuro-oncology and to develop standardized response criteria. RAPNO was subsequently established to address unique issues in pediatric neuro-oncology. The aim of this paper is to delineate response criteria issues in pediatric clinical trials as a basis for subsequent recommendations.

School-age effects of the newborn individualized developmental care and assessment program for preterm infants with intrauterine growth restriction: preliminary findings.

BACKGROUND: The experience in the newborn intensive care nursery results in premature infants' neurobehavioral and neurophysiological dysfunction and poorer brain structure. Preterms with severe intrauterine growth restriction are doubly jeopardized given their compromised brains. The Newborn Individualized Developmental Care and Assessment Program improved outcome at early school-age for preterms with appropriate intrauterine growth. It also showed effectiveness to nine months for preterms with intrauterine growth restriction. The current study tested effectiveness into school-age for preterms with intrauterine growth restriction regarding executive function (EF), electrophysiology (EEG) and neurostructure (MRI). METHODS: Twenty-three 9-year-old former growth-restricted preterms, randomized at birth to standard care (14 controls) or to the Newborn Individualized Developmental Care and Assessment Program (9 experimentals) were assessed with standardized measures of cognition, achievement, executive function, electroencephalography, and magnetic resonance imaging. The participating children were comparable to those lost to follow-up, and the controls to the experimentals, in terms of newborn background health and demographics. All outcome measures were corrected for mother's intelligence. Analysis techniques included two-group analysis of variance and stepwise discriminate analysis for the outcome measures, Wilks' lambda and jackknifed classification to ascertain two-group classification success per and across domains; canonical correlation analysis to explore relationships among neuropsychological, electrophysiological and neurostructural domains at school-age, and from the newborn period to school-age. RESULTS: Controls and experimentals were comparable in age at testing, anthropometric and health parameters, and in cognitive and achievement scores. Experimentals scored better in executive function, spectral coherence, and cerebellar volumes. Furthermore, executive function, spectral coherence and brain structural measures discriminated controls from experimentals. Executive function correlated with coherence and brain structure measures, and with newborn-period neurobehavioral assessment. CONCLUSION: The intervention in the intensive care nursery improved executive function as well as spectral coherence between occipital and frontal as well as parietal regions. The experimentals' cerebella were significantly larger than the controls'. These results, while preliminary, point to the possibility of long-term brain improvement even of intrauterine growth compromised preterms if individualized intervention begins with admission to the NICU and extends throughout transition home. Larger sample replications are required in order to confirm these results. CLINICAL TRIAL REGISTRATION: The study is registered as a clinical trial. The trial registration number is NCT00914108.

Clinical practice guidelines (CPGs) reduce costs in the management of isolated splenic injuries at pediatric trauma centers.

PURPOSE: The American Pediatric Surgical Association Trauma Committee proposed the use of a clinical practice guideline (CPG) for the non-operative management of isolated splenic injuries in 1998. An analysis was conducted to determine the financial impact of CPGs on the management of these injuries. METHODS: The Pediatric Health Information System database, which contains data from 44 children's hospitals, was used to identify children who sustained a graded isolated splenic injury between June 2005 and June 2010. Demographics, length of stay (LOS), readmission rates, and laboratory, imaging, procedural, and total cost data were determined for all hospitals verified as a pediatric trauma center by the American College of Surgeons and/or designated by their local authority. Comparisons were made between facilities self-identifying as having a splenic injury management CPG and those without a CPG. RESULTS: Children (1,154) with isolated splenic injuries (grades 1-4) were cared for in 26 pediatric trauma centers: 20 with a CPG and 6 without (non-CPG). Median costs were significantly lower at CPG than non-CPG centers for imaging (US $163 vs. US $641, P < .001), laboratory (US $629 vs. US $1,044, P < .001), and total hospital stay (US $9,868 vs. US $10,830, P < .001). The median LOS for CPG and non-CPG centers were similar (3 vs. 2 days, P = .38), as were readmission rates within 90 days (3.1 vs. 5.1 %, P = .21). Multiple linear regression indicated that LOS (P < .001) and utilization of a CPG (P = .007) are significant independent predictors of total cost. CONCLUSIONS: Utilization of a CPG to manage children with isolated splenic injuries at a pediatric trauma center results in significantly reduced imaging, laboratory, and total hospital costs independent of patient age, gender, grade, and LOS.

Treatment of perforated appendicitis in children: what is the cost?

BACKGROUND/PURPOSE: We compared direct hospital costs and indirect costs to the family associated with immediate appendectomy or initial nonoperative management for perforated appendicitis in children. METHODS: From June 2009 through May 2010, 61 prospectively identified families completed a cost diary, documenting the numbers of missed school days for the child and missed employment days for the adult caregiver(s) over the treatment course. Hospital costs were obtained from hospital financial databases. Mann-Whitney U tests and Fisher exact tests were used to compare outcome measures for each treatment strategy. RESULTS: Patients treated by initial nonoperative management had a significantly longer median length of stay (9 days vs 7 days, P = .02) and a significantly greater median total hospital cost per patient ($31,349 vs $21,323, P = .01) when compared with those treated by immediate appendectomy. There was no significant difference in median number of missed school days (9 days vs 10 days, P = .23) or missed employment days for adult caregiver(s) (5 days vs 7 days, P = .18) between treatment strategies. CONCLUSIONS: Patients with perforated appendicitis treated by initial nonoperative management had a greater length of stay and a significantly greater total hospital cost but were not burdened by significantly greater indirect costs compared with those treated by immediate appendectomy.
