RESUMEN

BACKGROUND: Pectus excavatum (PE) is a common congenital chest wall deformity with various associated health concerns, including psychosocial impacts, academic challenges, and potential cardiopulmonary effects. OBJECTIVE: This study aimed to investigate the cardiac consequences of right atrioventricular groove compression in PE using cardiac magnetic resonance imaging. MATERIALS AND METHODS: A retrospective analysis was conducted on 661 patients with PE referred for evaluation. Patients were categorized into three groups based on the degree of right atrioventricular groove compression (no compression (NC), partial compression (PC), and complete compression(CC)). Chest wall indices were measured: pectus index (PI), depression index (DI), correction index (CI), and sternal torsion. RESULTS: The study revealed significant differences in chest wall indices between the groups: PE, NC=4.15 ± 0.94, PC=4.93 ± 1.24, and CC=7.2 ± 4.01 (P<0.0001). Left ventricle ejection fraction (LVEF) showed no significant differences: LVEF, NC=58.72% ± 3.94, PC=58.49% ± 4.02, and CC=57.95% ± 3.92 (P=0.0984). Right ventricular ejection fraction (RVEF) demonstrated significant differences: RVEF, NC=55.2% ± 5.3, PC=53.8% ± 4.4, and CC=53.1% ± 4.8 (P≥0.0001). Notably, the tricuspid valve (TV) measurement on the four-chamber view decreased in patients with greater compression: NC=29.52 ± 4.6; PC=28.26 ± 4.8; and CC=24.74 ± 5.73 (P<0.0001). CONCLUSION: This study provides valuable insights into the cardiac consequences of right atrioventricular groove compression in PE and lends further evidence of mild cardiac changes due to PE.

RESUMEN

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.

RESUMEN

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. LEVEL OF EVIDENCE: Level III.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Exercise intolerance and chest pain are common symptoms in patients with pectus excavatum. To assess if the anatomic extent of pectus deformities determined by the correction index (CI) is associated with a pulmonary impairment at rest and during exercise we performed a retrospective review on pectus patients in our center who completed a symptom questionnaire, cardiopulmonary exercise test (CPET), pulmonary function tests (PFT), and chest magnetic resonance imaging. Of 259 patients studied, dyspnea on exertion and chest pain was reported in 64% and 41%, respectively. Peak oxygen uptake (VO2 ) was reduced in 30% and classified as mild in two-thirds. A pulmonary limitation during exercise was identified in less than 3%. Ventilatory limitations on PFT was found in 26% and classified as mild in 85%. Obstruction was the most common abnormal pattern (11%). There were no differences between patients with normal or abnormal PFT patterns for the CI, VO2, or percentage reporting dyspnea or chest pain. Scatter plots demonstrated significant but weak inverse relationships between the CI and lung volumes at rest and during exercise. Multivariable linear regression modeling evaluating predictors of VO2 demonstrated positive associations with the forced expiratory volume at one second and a negative association with the CI. We conclude that resting PFT patterns have poor correlation with the anatomic extent of the pectus defect, symptomatology or aerobic fitness. Pulmonary limitations on CPET are uncommon and lung volumes during exercise are only minimally associated with the CI.

RESUMEN

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.

RESUMEN

This study aimed to assess the effects of sodium caseinate and cholesterol to extenders used for stallion semen cooling. Two ejaculates from 19 stallions were extended to 50 million/mL in four different extenders and cooled-stored for 24 hours at 5°C. The extender 1 (E1) consisted of a commercially available skim milk-based extender. The extender 2 (E2) consisted of E1 basic formula with the milk component being replaced by sodium caseinate (20 g/L). The extender 3 (E3) consisted of E1 basic formula added to cholesterol (1.5 mg/120 million sperm). The extender 4 (E4) consisted of a combination of the E2 added to cholesterol. At 24 hours after cooling, sperm motility parameters, plasma membrane stability (PMS), and mitochondrial membrane potential were assessed. In addition, cooled semen (1 billion sperm at 5°C/24 hours) from one "bad cooler" and one "good cooler" stallions, split into four extenders was used to inseminate 30 light breed mares (30 estrous cycles/extender). Milk-based extenders (E1 and E2) had superior sperm kinetics than E3 and E4 (P < .05). Plasma membrane stabilization was significantly higher (P < .05) in E4 than E1, whereas E2 and E3 presented intermediate values (P > .05). The mitochondrial potential intensity was lower (P < .05) in E2 and E4 groups compared with E1 and E3. The good cooler stallion had high fertility (∼80%) in all extenders. However, for bad cooler stallion, E1 40% (8/20) and E2 45% (9/20) had poor fertility (P < .05) compared with E4 85% (17/20), whereas E3 55% (11/20) had intermediate value (P > .05). In conclusion, the association of sodium caseinate and cholesterol improved fertility of bad cooler stallion semen cooled for 24 hours.

RESUMEN

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.

RESUMEN

AIMS: To investigate the right ventricular (RV) strain in pectus excavatum (PE) patients using cardiac magnetic resonance tissue tracking (CMR TT). MATERIALS AND METHODS: Fifty consecutive pectus excavatum patients, 10 to 32 years of age (mean age 15 ± 4 years), underwent routine cardiac magnetic resonance imaging (CMR) including standard measures of chest geometry and cardiac size and function. The control group consisted of 20 healthy patients with a mean age of 17 ± 5 years. RV longitudinal and circumferential strain magnitude was assessed by a dedicated RV tissue tracking software. RESULTS: Fifty patients with images of sufficient quality were included in the analysis. The mean right and left ventricular ejection fractions were 55 ± 5% and 59 ± 4%. The RV global longitudinal strain was -21.88 ± 4.63%. The RV circumferential strain at base, mid-cavity and apex were -13.66 ± 3.09%, -11.31 ± 2.79%, -20.73 ± 3.45%, respectively. There was no statistically significant decrease in right ventricular or left ventricular ejection fraction between patients and controls (p > 0.05 for each). There was no significant difference in RV global longitudinal strain between two groups (-21.88 ± 4.63 versus -21.99 ± 3.58; p = 0.93). However, there was significant decrease in mid-cavity circumferential strain magnitude in pectus patients compared with controls (-11.31 ± 2.79 versus -16.19 ± 2.86; p < 0.001). PE patients had a significantly higher basal circumferential strain (-13.66 ± 3.09% versus -9.76 ± 1.79; p < 0.001) as well as apical circumferential strain (-20.73 ± 3.45% versus -12.07 ± 3.38) than control group. CONCLUSION: Mid-cavity circumferential strain but not longitudinal strain is reduced in pectus excavatum patients. Basal circumferential strain as well as apical circumferential strain were increased as compensatory mechanism for reduced mid-cavity circumferential strain. Further studies are needed to establish clinical significance of this finding.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVES: The purpose of this study was to identify, among emergency department (ED) physicians, the potential barriers impacting the appropriate and timely transfer of injured children to pediatric trauma centers. METHODS: Surveys assessed pediatric trauma knowledge and experience, transfer and imaging decisions, and perceived barriers to patient transfer. Two scenarios were created; one with a child meeting the state trauma triage criteria and one who did not. In April 2010, 936 surveys were mailed to randomly selected ED physicians. Respondents could answer by mail or online until June 30, 2010. RESULTS: A total of 486 surveys were returned, and 109 were excluded, leaving 377 included in the study. A majority reported limited experience in the care of the critically ill child, with 93%, 99%, 99%, and 100% respectively, having performed less than 5 intubations, intraosseous line, central line, or chest tube placements in the last year. In the scenario in which the child met criteria to be transferred, 74% appropriately transferred the patient, whereas in the other scenario, 34% transferred the patient. As much as 56% of the respondents reported they would perform a head computed tomography before transfer, mainly to avoid missed injuries and medicolegal concerns. Among those who would not transfer either patient, 27% reported not having an on-call surgeon at all times. CONCLUSIONS: Innovative measures should be developed so that ED physicians gain a greater understanding of the proper identification of pediatric patients requiring a timely transfer to a pediatric trauma center.

RESUMEN

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.

RESUMEN

OBJECTIVES: Timely transfer of injured children to pediatric trauma centers (PTCs) that can address their unique needs is important. This study was designed to understand the characteristics of transferred injured children. METHODS: Data from our level I PTC over 5 years (2002-2006) were reviewed. Transferred patients were divided based on time from injury to arrival at our PTC: early (<2 hours) and late (>2 hours). Data collected included demographics, Injury Severity Scale score, Glasgow Coma Scale score, mode of transportation, referring hospital information including pretransfer imaging, and disposition from our emergency room. RESULTS: Seven hundred forty-eight patients were included. Eighty-two percent (n = 612) were in the late group and arrived, on average, 6 hours after those transferred early (420 vs 69.9 minutes, P < 0.05). Seventy-nine percent (n = 147) of transfers with severe injuries (Injury Severity Scale score >15) and 47% (n = 15) of those with severe head injuries (Glasgow Coma Scale score <8) arrived late. The disproportionate number of late transfers was consistent among all transferring hospitals regardless of distance and only slightly improved in the group transferred by air ambulance. In addition, those transferred late had significantly more pretransfer imaging (49% vs 23%, P = 0.0025). CONCLUSIONS: Despite the advantages of care in trauma centers, a significant number of severely injured children are transferred well beyond 2 hours after injury. This study has demonstrated that this pattern of delayed transfer is a systemic problem occurring among all transferring hospitals regardless of distance or mode of patient transfer and is associated with increased use of imaging before transfer.
