(F)utility of preoperative pulmonary function testing in pectus excavatum to assess severity.

PURPOSE: The utility of pulmonary function testing (PFT) in pectus excavatum (PE) has been subject to debate. Although some evidence shows improvement from preoperative to postoperative values, the clinical significance is uncertain. A high failure-to-completion rate for operative PFT (48%) was identified in our large institutional cohort. With such a high non-completion rate, we questioned the overall utility of PFT in the preoperative assessment of PE and sought to evaluate if other measures of PE severity or cardiopulmonary function could explain this finding. METHODS: Demographics, clinical findings, and results from cardiac MRI, PFT (spirometry and plethysmography), and cardiopulmonary exercise tests (CPET) were reviewed in 270 patients with PE evaluated preoperatively between 2015 and 2018. Regression modeling was used to measure associations between PFT completion and cardiopulmonary function. RESULTS: There were no differences in demographics, symptoms, connective tissue disorders, or multiple indices of pectus severity and cardiac deformation in PFT completers versus non-completers. While regression analysis revealed higher RVEF, LVEF, and LVEF-Z scores, lower RV-ESV/BSA, LV-ESV/BSA, and LV-ESV/BSA-Z scores, and abnormal breathing reserve in PFT completers vs. non-completers, these findings were not consistent across continuous and binary analyses. CONCLUSIONS: We found that PFT completers were not significantly different from non-completers in most structural and functional measures of pectus deformity and cardiopulmonary function. Inability to complete PFT is not an indicator of pectus severity.

Outcomes From a Nurse Practitioner Led Dynamic Compression System Bracing Program for Pectus Carinatum.

BACKGROUND: Dynamic compression system (DCS) is often effective at treating pectus carinatum (PC). However, some patients will fail therapy. This study reports outcomes from a nurse-practitioner led bracing program, and evaluates what factors are predictive of successful therapy. METHODS: We performed a retrospective cohort study involving all patients treated with DCS bracing at our institution between February 2018 and February 2022. Patients with at least three visits were included. The primary outcome was achieving neutral chest. Factors considered potentially predictive included patient age, sex, initial pressure of correction (PIC), and the change in pressure of correction between the first two visits (deltaPC1). A Cox proportional hazards model was used for analysis, and Kaplan-Meier analyses estimated the median time to correction. RESULTS: 283 patients were evaluated. The median age was 14 (IQR 12-15), the majority were male (90.1 %) and white (92.6 %). The median PIC and deltaPC1was 4.13 PSI (IQR 3.17-5.3), and 1.34 PSI (IQR 0.54-2.25), respectively. 117 patients achieved correction. The median estimated time to correction was 7.5 months (95 % CI 5.9-10.1). In the final Cox model, greater deltaPC1 was associated with increased risk of correction (HR: 2.46; 95 % CI 2.03-2.98), and increased PIC was associated with decreased risk of correction up to one year of therapy (0-3 months HR 0.62, 95 % CI 0.50-0.78; 3-12 months HR 0.62; 95 % CI 0.45-0.85). CONCLUSIONS: DCS bracing administered by advanced care providers in collaboration with surgeons can effectively treat PC. The deltaPC1 and PIC are the factors most predictive of successful therapy.

Retrospective study comparing outcomes of multimodal epidural and erector spinae catheter pain protocols after pectus surgery.

INTRODUCTION: There are no optimal postoperative analgesia regimens for Nuss procedures. We compared the effectiveness of thoracic epidurals (EPI) and novel ambulatory erector spinae plane (ESP) catheters as part of multimodal pain protocols after Nuss surgery. METHODS: Data on demographics, comorbidities, perioperative details, length of stay (LOS), in hospital and post discharge pain/opioid use, side effects, and emergency department (ED) visits were collected retrospectively in children who underwent Nuss repair with EPI (N = 114) and ESP protocols (N = 97). Association of the group with length of stay (LOS), in hospital opioid use (intravenous morphine equivalents (MEq)/kg over postoperative day (POD) 0-2), and oral opioid use beyond POD7 was analyzed using inverse probability of treatment weighting (IPTW) with propensity scores, followed by multivariable regression. RESULTS: Groups had similar demographics. Compared to EPI, ESP had longer block time and higher rate of ketamine and dexmedetomidine use. LOS for ESP was 2 days IQR (2, 2) compared to 3 days IQR (3, 4) for EPI (p < 0.01). Compared to EPI, ESP group had higher opioid use (in MEq/kg) intraoperatively (0.32 (IQR 0.27, 0.36) vs. 0.28 (0.24, 0.32); p < 0.01) but lower opioid use on POD 0 (0.09 (IQR 0.04, 0.17) vs. 0.11 (0.08, 0.17); p = 0.03) and POD2 (0.00 (IQR 0.00, 0.00) vs. 0.04 (0.00, 0.06) ; p < 0.01). ESP group also had lower total in hospital opioid use (0.57 (IQR 0.42, 0.73) vs.0.82 (0.71, 0.91); p < 0.01), and shorter duration of post discharge opioid use (6 days (IQR 5,8) vs. 9 days (IQR 7,12) (p < 0.01). After IPTW adjustment, ESP continued to be associated with shorter LOS (difference -1.20, 95% CI: -1.38, -1.01, p < 0.01) and decreased odds for opioid use beyond POD7 (OR 0.11, 95% CI: 0.05, 0.24); p < 0.01). However, total in hospital opioid use in MEq/kg (POD0-2) was now similar between groups (difference -0.02 (95% CI: -0.09, -0.04); p = 0.50). The EPI group had higher incidence of emesis (29% v 4%, p < 0.01), while ESP had higher catheter malfunction rates (23% v 0%; p < 0.01) but both groups had comparable ED visits/readmissions. DISCUSSION/CONCLUSION: Compared to EPI, multimodal ambulatory ESP protocol decreased LOS and postoperative opioid use, with comparable ED visits/readmissions. Disadvantages included higher postoperative pain scores, longer block times and higher catheter leakage/malfunction. LEVELS OF EVIDENCE: Level III.

Does age matter? Cardiopulmonary profiles of adolescents versus adults with pectus excavatum presenting for surgical evaluation.

PURPOSE: We sought to analyze differences in presentation and cardiopulmonary function between those referred for surgical consultation as adolescents (11-17 years) versus adults (18 + years). METHODS: Presenting symptoms, past medical history, and results from cardiac MRI (CMR), pulmonary function testing (PFT), and cardiopulmonary exercise testing (CPET) were reviewed in 329 patients evaluated preoperatively between 2015 and 2018. Adjusted regression modeling was used to measure associations between pectus indices and clinical endpoints of cardiopulmonary function. RESULTS: Our sample included 276 adolescents and 53 adults. Adults presented more frequently with chest pain (57% vs. 38%, p = 0.01), shortness of breath (76% vs. 59%, p = 0.02), palpitations (21% vs. 11%, p = 0.04), and exercise intolerance (76% vs. 59%, p = 0.02). Their Haller indices (5.2 [4.2, 7.0] vs. 4.7 [4.0, 5.7], p = 0.05) and cardiac asymmetry (1.8 [0.5] vs. 1.6 [0.5], p = 0.02) were also higher. In continuous outcome analysis, adolescents had higher FEV1/FVC on PFT and higher work on CPET (p < 0.01). CONCLUSIONS: Adults with pectus excavatum were more symptomatic than adolescents with deeper, more asymmetric deformities, decreased FEV1/FVC and exercise capacity. These findings may support earlier versus later repair to prevent age-related decline. Further studies are warranted.

The Severity of Pectus Excavatum Defect Is Associated With Impaired Cardiopulmonary Function.

BACKGROUND: Repair of pectus excavatum has cosmetic benefits, but the physiologic impact remains controversial. The aim of this study was to characterize the relationship between the degree of pectus excavatum and cardiopulmonary dysfunction seen on cardiac magnetic resonance (CMR) imaging, cardiopulmonary exercise testing (CPET), and pulmonary function testing (PFT). METHODS: A single-center analysis of CMR, CPET, and PFT was conducted. Regression models evaluated relationships between pectus indices and the clinical end points of cardiopulmonary function. RESULTS: Data from 345 CMRs, 261 CPETs, and 281 PFTs were analyzed. Patients were a mean age of 15.2 ± 4 years, and 81% were aged <18 years. The right ventricular ejection fraction (RVEF) was <0.50 in 16% of patients, left ventricular ejection fraction (LVEF) was <0.55 in 22%, RVEF Z-score was < -2 in 32%, and the LVEF Z-score was < -2 in 18%. CPET revealed 33% of patients had reduced aerobic fitness. PFT results were abnormal in 23.1% of patients. Adjusted analyses revealed the Haller index had significant (P < .05) inverse associations with RVEF and LVEF. CONCLUSIONS: The severity of pectus excavatum is associated with ventricular systolic dysfunction. Pectus excavatum impacts right and left ventricular systolic function and can also impact exercise tolerance. The Haller index and correction index may be the most useful predictors of impairment.

Standardization of clinical care pathway leads to sustained decreased length of stay following Nuss pectus repair: A multidisciplinary quality improvement initiative.

BACKGROUND AND PURPOSE: Postoperatively, standardized clinical care pathways (SCCPs) help patients reach necessary milestones for discharge. The objective of this study was to achieve 90% compliance with a pectus specific SCCP within 9 months of implementation. We hypothesized that adherence to a pectus SCCP following the Nuss procedure would decrease postsurgical length of stay (LOS). METHODS: A multidisciplinary team implemented the pectus SCCP, including goals for mobility, lung recruitment, pain control, intake, and output. The full protocol included 42 components, tracked using chart reviews and a patient-directed checklist. The primary process measure was compliance with the pectus SCCP. The primary outcome measure was LOS; secondary outcomes were patient charges, patient satisfaction, and hospital readmission. RESULTS: Total study patients were n = 509: 159 patients pre-intervention, 350 patients post-intervention (80 implementation group; 270 sustain group). SCCP compliance data were collected on 164 patients post-intervention - 80 implementation, 84 sustain. LOS, ED visits, and hospital readmissions were recorded for all 509 patients. Mean LOS decreased from 4.5 days to 3.4 days, with >90% adherence to the pectus SCCP postintervention. There were no readmissions owing to pain despite earlier termination of epidural analgesia. Total patient charges decreased by 30% and patient satisfaction was high. CONCLUSION: Using quality improvement methodology with strict adherence to a pectus SCCP, we had significant reduction in LOS and patient charge without compromising effective postoperative pain management or patient satisfaction. TYPE OF STUDY: Clinical research; quality improvement. LEVEL OF EVIDENCE: V.

The chest wall gender divide: females have better cardiopulmonary function and exercise tolerance despite worse deformity in pectus excavatum.

PURPOSE: Pectus excavatum (PE) is a chest wall deformity of variable severity and symptomatology. Existing female-specific literature highlights breast asymmetry and cosmetic reconstruction. We sought to evaluate gender differences in cardiopulmonary function. METHODS: Cardiac MRIs, pulmonary function tests (PFTs), and cardiopulmonary exercise tests (CPETs) were reviewed in 345 patients undergoing preoperative evaluation for PE. Regression modeling was used to evaluate associations between gender and clinical endpoints of cardiopulmonary function. RESULTS: Mean age was 15.2 years, 19% were female, 98% were white. Pectus indices included median Haller Index (HI) of 4.8, mean depression index (DI) of 0.63, correction index (CI) of 33.6%, and Cardiac Compression Index (CCI) of 2.79. Cardiac assessment revealed decreased right and left ventricular ejection fraction (RVEF, LVEF) in 16% and 22% of patients, respectively. PFTs and CPETs were abnormal in ~ 30% of patients. While females had deeper PE deformities-represented by higher pectus indices-they had superior function with higher RVEF, LVEF Z-scores, FEV1, VO2 max, O2 pulse, work, and breathing reserve (p < 0.05). CONCLUSION: Despite worse PE deformity and symptomatology, females had a better cardiopulmonary function and exercise tolerance than males. Further research is needed to assess the precise mechanisms of this phenomenon and postoperative outcomes in this population.

A paradigm for achieving successful pediatric trauma verification in the absence of pediatric surgical specialists while ensuring quality of care.

BACKGROUND: Pediatric trauma centers (PTCs) are concentrated in urban areas, leaving large areas where children do not have access. Although adult trauma centers (ATCs) often serve to fill the gap, disparities exist. Given the limited workforce in pediatric subspecialties, many adult centers that are called upon to care for children cannot sufficiently staff their program to meet the requirements of verification as a PTC. We hypothesized that ATCs in collaboration with a PTC could achieve successful American College of Surgeons (ACS) verification as a PTC with measurable improvements in care. This article serves to provide an initial description of this collaborative approach. METHODS: Beginning in 2008, a Level I PTC partnered with three ATC seeking ACS-PTC verification. The centers adopted a plan for education, simulation training, guidelines, and performance improvement support. Results of ACS verification, patient volumes, need to transfer patients, and impact on solid organ injury management were evaluated. RESULTS: Following partnership, each of the ATCs has achieved Level II PTC verification. As part of each review, the collaborative was noted to be a significant strength. Total pediatric patient volume increased from 128.1 to 162.1 a year (p = 0.031), and transfers out decreased from 3.8% to 2.4% (p = 0.032) from prepartnership to postpartnership periods. At the initial ATC partner site, 10.7 children per year with solid organ injury were treated before the partnership and 11.8 children per year after the partnership. Following partnership, we found significant reductions in length of stay, number of images, and laboratory draws among this limited population. CONCLUSION: The collaborative has resulted in ACS Level II PTC verification in the absence of on-site pediatric surgical specialists. In addition, more patients were safely cared for in their community without the need for transfer with improved quality of care. This paradigm may serve to advance the care of injured children at sites without access to pediatric surgical specialists through a collaborative partnership with an experienced Level I PTC. Further risk-adjusted analysis of outcomes will need to be performed in the future. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

Perioperative outcome of laparoscopic Roux-en-Y gastric bypass: a children's hospital experience.

BACKGROUND/PURPOSE: To evaluate the perioperative safety of laparoscopic Roux-en-Y gastric bypass (LRYGB) in a freestanding children's hospital setting. PATIENTS AND METHODS: Perioperative (<90 days) clinical complications of 77 consecutive patients (mean age 16.8 ± 2.1 years: mean BMI 59.4 kg/m(2), 68% female), who underwent LRYGB at Cincinnati Children's Hospital from 2002 to 2007 were examined, using standardized data collection forms that were created specifically for use in this study. RESULTS: No mortality or conversion to open surgery was observed. Intraoperative complications were uncommon (3%). No anesthetic complications or transfusion requirements were observed. Median hospital stay was 3 days. Twenty-two percent of subjects had a complication from discharge to 30 days, while 13% experienced a complication between 31 and 90 days. The common types of postoperative complications included gastrojejunal anastomotic stricture (17%), leak (7%), dehydration (7%), and small bowel obstruction (SBO; 5%). Reoperation was required in 9 subjects. Operating time significantly decreased as the number of cases performed increased. CONCLUSIONS: LRYGB in this case series of adolescents was associated with a low rate of intraoperative complications, with an increased rate over the ensuing 90 days. These events can be successfully managed, even in super obese adolescents.

Role of computed tomography and clinical findings in pediatric blunt intestinal injury: a multicenter study.

PURPOSE: Although computed tomographic (CT) scans are accurate in diagnosing solid-organ injuries, their ability to diagnose a blunt intestinal injury (BII) is limited, occasionally requiring repeated imaging. The purpose of this study was to evaluate the role of clinical findings as well as original and repeated CT imaging in the ultimate decision to operate for BII. METHODS: An 18-institution record review of children (≤ 15 years) diagnosed with a BII confirmed during surgery between 2002 and 2007 was conducted by the American Pediatric Surgery Association Trauma Committee. The incidence of imaging, repeated imaging, and final reported indications for operative exploration were evaluated. RESULTS: Among 331 patients identified with a BII, 292 (88%) underwent at least 1 abdominal CT scan. Sixty-two (19%) underwent at least 1 repeated scan before operation. Forty-seven percent of children who underwent a CT scan were taken to the operating room based primarily on clinical indications (fever, abdominal pain, shock or elevated white blood cell count), whereas 31% were operated on based on both a clinical and CT indication and 22% were operated on based on a CT indication alone (P < 0.001). Although free air was the most common radiographic indication for surgery, 13% of patients with a repeated scan had free air diagnosed on their first CT. Most children undergoing a repeated CT (84%) had findings on the original scan suggesting a BII. Among the 10 patients whose first CT scan result was normal, only 1 went to the operating room based only on radiographic findings. Children who had their first CT scan at a referring hospital were more likely to have a repeated study compared with those imaged at a trauma center (33% vs 13%, P < 0.0001). CONCLUSIONS: Although abdominal CT imaging may contribute to diagnosing intestinal injury after blunt trauma, most children undergo operation based on clinical findings. Repeated imaging should be limited to select patients with diagnostic uncertainty to avoid unneeded delay and radiation exposure.

Use of a mild traumatic brain injury guideline to reduce inpatient hospital imaging and charges.

PURPOSE: In children, mild traumatic brain injuries (TBI) account for 70% to 90% of head injuries. Without clear guidelines, many of these children may be exposed to excess radiation owing to unnecessary imaging. The purpose of this study was to evaluate the impact of a mild TBI guideline in reducing hospital charges and repeated imaging of pediatric patients. METHODS: Charts of all children who had at least one head computed tomography and were admitted to our level 1 trauma center with a blunt TBI and Glasgow Coma Scale of 13 to 15 were retrospectively reviewed. Patients were divided into 2 groups relative to the implementation of a TBI management guideline. RESULTS: A total of 742 patients were included, 389 preguideline and 353 postguideline. Implementation of the guideline was associated with reductions in the average number of head computed tomographies performed (1.6 vs 1.3, P = .006), length of stay (2.3 vs 1.7 days, P < .0001), and overall hospital charges ($21,760 vs $13,980, P = .006). No children were readmitted for missed injuries. CONCLUSIONS: Implementation of a simple guideline for the care of children with mild TBI can have significant impact on charges and length of stay while simultaneously reducing radiation exposure. Widespread implementation of such guidelines will improve efficiency without sacrificing quality of care in the management of mild TBI in the pediatric population.

Baseline BMI is a strong predictor of nadir BMI after adolescent gastric bypass.

OBJECTIVE: Surgical treatment of extreme obesity may be appropriate for some adolescents. We hypothesized that surgical weight loss outcomes may differ by preoperative level of extreme obesity (body mass index [BMI] > or=99th percentile). STUDY DESIGN: A longitudinal assessment of clinical characteristics from 61 adolescents who underwent laparoscopic Roux-en-Y gastric bypass at a single pediatric center from 2002 until 2007 was performed. Patients were categorized into 1 of 3 preoperative BMI groups: group 1, BMI = 40.0 to 54.9 (n = 23); group 2, BMI = 55.0 to 64.9 (n = 21); group 3, BMI = 65.0 to 95.0 (n = 17). Changes in BMI and cardiovascular risk factors between baseline and year 1 were evaluated using repeated-measures mixed linear modeling. RESULTS: BMI in the overall cohort at baseline (60.2 +/- 11 kg/m(2)) decreased by 37.4% at 1 year after surgery (P < .001). Percent BMI change varied little by preoperative BMI groups (-37.2%, -36.8%, and -37.7% for groups 1, 2, and 3 respectively; P = .8762). The rate of change in absolute BMI units significantly varied by preoperative BMI class (group x time interaction, P < .0001), with 1-year nadir BMI values for groups 1, 2, and 3 falling to 31 +/- 4 kg/m(2), 38 +/- 5 kg/m(2), and 47 +/- 9 kg/m(2), respectively. One year after surgery, only 17% of patients achieved a nonobese BMI (<30 kg/m(2)). Significant improvements in systolic and diastolic blood pressure (P < .0001), fasting insulin (P < .0001), total cholesterol (P = .0007), and triglyceride levels (P < .0001) were seen after surgery irrespective of baseline BMI class. Mean albumin levels remained normal despite significant caloric restriction and weight loss. CONCLUSIONS: Laparoscopic gastric bypass resulted in improvement or reversal of cardiovascular risk factors and resulted in a decrease in BMI of approximately 37% in all patients, regardless of starting BMI, 1 year after surgery. The timing of surgery for adolescent extreme obesity is an important consideration, because "late" referral for bariatric surgery at the highest of BMI values may preclude reversal of obesity.

Severity of head computed tomography scan findings fail to explain racial differences in mortality following child abuse.

INTRODUCTION: Differences in head injury severity may not be fully appreciated in child abuse victims. The purpose of this study was to determine if differential findings on initial head computed tomography (CT) scan could explain observed differential outcome by race. METHODS: We identified 164 abuse patients from our trauma registry with an Injury Severity Score (ISS) > or = 15. Their initial head CT scan was graded from 1 to 4 (normal to severe). Statistical analysis was performed to asses the correlation between race, head CT grade, Glasgow Coma Scale (GCS) score, and mortality. RESULTS: Overall mortality was 17%: 11% for white children, 32% for African-American children (P < .05). In review of the head CT scans there was no difference by race in types of injuries or head CT grade. Using a multivariate regression model, African-American race remained an independent risk factor for mortality with an odd ratio of 4.3 (95% confidence interval [CI] 1.6-11.5). CONCLUSION: African-American children had a significantly higher mortality rate despite similar findings on initial head CT scans. Factors other than injury severity may explain these disparate outcomes.

Reversal of type 2 diabetes mellitus and improvements in cardiovascular risk factors after surgical weight loss in adolescents.

OBJECTIVES: Type 2 diabetes mellitus is associated with obesity, dyslipidemia, and hypertension, all well-known risk factors for cardiovascular disease. Surgical weight loss has resulted in a marked reduction of these risk factors in adults. We hypothesized that gastric bypass would improve parameters of metabolic dysfunction and cardiovascular risk in adolescents with type 2 diabetes mellitus. PATIENTS AND METHODS: Eleven adolescents who underwent Roux-en-Y gastric bypass at 5 centers were included. Anthropometric, hemodynamic, and biochemical measures and surgical complications were analyzed. Similar measures from 67 adolescents with type 2 diabetes mellitus who were treated medically for 1 year were also analyzed. RESULTS: Adolescents who underwent Roux-en-Y gastric bypass were extremely obese (mean BMI of 50 +/- 5.9 kg/m(2)) with numerous cardiovascular risk factors. After surgery there was evidence of remission of type 2 diabetes mellitus in all but 1 patient. Significant improvements in BMI (-34%), fasting blood glucose (-41%), fasting insulin concentrations (-81%), hemoglobin A1c levels (7.3%-5.6%), and insulin sensitivity were also seen. There were significant improvements in serum lipid levels and blood pressure. In comparison, adolescents with type 2 diabetes mellitus who were followed during 1 year of medical treatment demonstrated stable body weight (baseline BMI: 35 +/- 7.3 kg/m(2); 1-year BMI: 34.9 +/- 7.2 kg/m(2)) and no significant change in blood pressure or in diabetic medication use. Medically managed patients had significantly improved hemoglobin A1c levels over 1 year (baseline: 7.85% +/- 2.3%; 1 year: 7.1% +/- 2%). CONCLUSIONS: Extremely obese diabetic adolescents experience significant weight loss and remission of type 2 diabetes mellitus after Roux-en-Y gastric bypass. Improvements in insulin resistance, beta-cell function, and cardiovascular risk factors support Roux-en-Y gastric bypass as an intervention that improves the health of these adolescents. Although the long-term efficacy of Roux-en-Y gastric bypass is not known, these findings suggest that Roux-en-Y gastric bypass is an effective option for the treatment of extremely obese adolescents with type 2 diabetes mellitus.

Despite overall low pediatric head injury mortality, disparities exist between races.

BACKGROUND: To continually improve quality of care, it is important for centers caring for children with head injury to evaluate their overall outcome and that among diverse patient groups. METHODS: Data on children with head injuries were extracted from the National Trauma Data Bank of the American College of Surgeons and our local trauma registry. Unadjusted mortality, as well as stratified analysis and logistic regression modeling, was used to evaluate overall and race-specific mortality. RESULTS: There were 13,363 children in the National Trauma Data Base and 3111 in our database included. Our overall mortality rate compared favorably with the national data (3.2% vs 6.8%, P < .05). Our local data, however, showed a significant difference in mortality between white and African American (AA) children (2.2% vs 5.3%, P < .05), which was not identified in the national data. After stratification, the disparities by race persisted. Finally, multivariate regression modeling revealed that AA race was an independent predictor of mortality among our patient population, with an odds ratio of 3.1 (95% confidence interval, 1.2-7.8). CONCLUSION: Despite excellent outcomes for children with head injuries, we have uncovered unsettling inequities between AA and white children. These findings support the need to evaluate outcomes among specific groups to identify disparities that require further careful investigation.

Multidisciplinary pediatric trauma team training using high-fidelity trauma simulation.

BACKGROUND: Trauma resuscitations require a high level of team performance. This study evaluated the impact of a comprehensive effort to improve trauma care through multidisciplinary education and the use of simulation training to reinforce training and evaluate performance. METHODS: For a 1-year period, expanded trauma education including monthly trauma simulation sessions using high-fidelity simulators was implemented. All members of the multidisciplinary trauma resuscitation team participated in education, including simulations. Each simulation session included 2 trauma scenarios that were videotaped for debriefing as well as subsequent analysis of team performance. Scored simulations were divided into early (initial 4 months) and late (final 4 months) for comparison. RESULTS: For the first year of the program, 160 members of our multidisciplinary team participated in the simulation. In the early group, the mean percentage of appropriately completed tasks was 65%, whereas in the late group, this increased to 75% (P < .05). Improvements were also observed in initial assessment, airway management, management of pelvic fractures, and cervical spine care. CONCLUSIONS: Training of a multidisciplinary team in the care of pediatric trauma patients can be enhanced and evaluated through the use of high-fidelity simulation. Improvements in team performance using innovative technology can translate into more efficient care with fewer errors.

Reversibility of cardiac abnormalities in morbidly obese adolescents.

OBJECTIVES: The purpose of this study was to evaluate changes in cardiac geometry, systolic and diastolic function before and after weight loss in morbidly obese adolescents. BACKGROUND: Cardiac abnormalities are present in morbidly obese adolescents; however, it is unclear if they are reversible with weight loss. METHODS: Data from 38 adolescents (13 to 19 years; 29 females, 9 males, 33 Caucasians, 5 African Americans) were evaluated before and after bariatric surgery. Left ventricular mass (LVM), left ventricular (LV) geometry, systolic and diastolic function were assessed by echocardiography. Mean follow up was 10 +/- 3 months. RESULTS: Weight and body mass index decreased post-operatively (mean weight loss 59 +/- 15 kg, pre-operative body mass index 60 +/- 9 kg/m(2) vs. follow-up 40 +/- 8 kg/m(2), p < 0.0001). Change in LVM index (54 +/- 13 g/m(2.7) to 42 +/- 10 g/m(2.7), p < 0.0001) correlated with weight loss (r = 0.41, p = 0.01). Prevalence of concentric left ventricular hypertrophy (LVH) improved from 28% at pre-operative to only 3% at follow up (p = 0.007), and normal LV geometry improved from 36% to 79% at follow up (p = 0.009). Diastolic function also improved (mitral E/Ea lateral 7.7 +/- 2.3 at pre-operative vs. 6.3 +/- 1.6 at post-operative, p = 0.003). In addition, rate-pressure product improved suggesting decreased cardiac workload (p < 0.001). CONCLUSIONS: Elevated LVM index, concentric LVH, altered diastolic function, and cardiac workload significantly improve following surgically induced weight loss in morbidly obese adolescents. Large weight loss due to bariatric surgery improves predictors of future cardiovascular morbidity in these young people.

Alarming trends in the improper use of motor vehicle restraints in children: implications for public policy and the development of race-based strategies for improving compliance.

PURPOSE: Little is known regarding the patterns of appropriate restraint use among minority children involved in motor vehicle collisions. The purpose of this study was to characterize patterns of restraint use among children hospitalized after motor vehicle collision and to examine the effects of race and socioeconomic status on compliance. METHODS: All children admitted to our level I trauma center over a 10-year period were identified. Patterns of appropriate restraint use were compared between African American (AA) and white children. Compliance was also compared between children insured with Medicaid (as a surrogate for socioeconomic status) and those with private insurance coverage. RESULTS: One thousand two hundred sixty-eight patients were included with an overall restraint use of 44.8% with only 20.3% restrained properly. Compared with white children, AAs were significantly less likely to be properly restrained (12.7% vs 22.2%, P < .001) or to be restrained by any means (28.8% vs 48.7%, P < .001). The greatest disparity between groups was observed in the use of car seats (16.0% vs 47.4%, P < .001). Medicaid patients were less likely to be restrained compared with those with commercial insurance (40.6% vs 48.3%, P = .022); however, race remained a significant predictor of noncompliance after controlling for the effect of insurance status. CONCLUSIONS: These data demonstrate an alarming trend because nearly 80% of all children in our study were improperly restrained. Marked disparities in compliance were observed in the AA population even after controlling for insurance coverage. Future studies will need to further characterize the complex interplay between race and socioeconomic status with proper restraint use.

Disparities in child abuse mortality are not explained by injury severity.

BACKGROUND: Unadjusted abuse-related mortality has been demonstrated to be nearly 4-fold higher for African American (AA) children. Little is known about the etiology of this disparity. This study examines the importance of injury severity and initial presentation in explaining the observed disparity. METHOD: Our trauma database was reviewed to identify all abused patients admitted over a 10-year period. Outcomes among white and AA children were compared with specific attention to injury severity scores and initial presentation. Logistic regression and Cox proportional hazard analyses were performed to evaluate the impact of race on outcome. RESULTS: There were 443 abused children identified. Thirty-eight percent of the group was AA. The overall mortality was 7.7%; however, the AA mortality was significantly higher than white children (14.8% vs 3.3%; P < .05). After controlling for injury severity and physiology at presentation, the odds ratio of mortality for an AA child was 9.14 (95% confidence interval, 1.97-42.43). Survival analysis confirmed the disparity after revealing a hazard ratio of dying for AA children of 6.51 (95% confidence interval, 2.74-15.47) compared with white children. CONCLUSION: Despite attempts to control for the clinical presentation and injury severity of abused children, significant differences in mortality persist between AA and white children.
