RESUMO
OBJECTIVE: To develop a severity-adjusted, hospital-level benchmarking comparative performance report for postoperative organ space infection and antibiotic utilization in children with complicated appendicitis. BACKGROUND: No benchmarking data exist to aid hospitals in identifying and prioritizing opportunities for infection prevention or antimicrobial stewardship in children with complicated appendicitis. METHODS: This was a multicenter cohort study using NSQIP-Pediatric data from 16 hospitals participating in a regional research consortium, augmented with antibiotic utilization data obtained through supplemental chart review. Children with complicated appendicitis who underwent appendectomy from 07/01/2015 to 06/30/2020 were included. Thirty-day postoperative OSI rates and cumulative antibiotic utilization were compared between hospitals using observed-to-expected (O/E) ratios after adjusting for disease severity using mixed effects models. Hospitals were considered outliers if the 95% confidence interval for O/E ratios did not include 1.0. RESULTS: 1790 patients were included. Overall, the OSI rate was 15.6% (hospital range: 2.6-39.4%) and median cumulative antibiotic utilization was 9.0 days (range: 3.0-13.0). Across hospitals, adjusted O/E ratios ranged 5.7-fold for OSI (0.49-2.80, P=0.03) and 2.4-fold for antibiotic utilization (0.59-1.45, P<0.01). Three (19%) hospitals were outliers for OSI (1 high and 2 low performers), and eight (50%) were outliers for antibiotic utilization (5 high and 3 low utilizers). Ten (63%) hospitals were identified as outliers in one or both measures. CONCLUSIONS: A comparative performance benchmarking report may help hospitals identify and prioritize quality improvement opportunities for infection prevention and antimicrobial stewardship, as well as identify exemplar performers for dissemination of best practices.
RESUMO
INTRODUCTION: Parental health literacy and neighborhood socioeconomic disadvantage are associated with adverse health outcomes and increased health-care resource utilization in children. We sought to evaluate the association between community-level health literacy and neighborhood socioeconomic disadvantage and their relationships with outcomes of pediatric patients undergoing gastrostomy tube (GT) placement. METHODS: Pediatric patients who underwent GT placement from 2000 to 2019 were identified using the IBM MarketScan Research database. Claims data were merged with the health literacy index (HLI) and area deprivation index (ADI), measures of community-level health literacy and neighborhood socioeconomic disadvantage, respectively. We used multivariate logistic regression to estimate factors associated with postoperative 30- and 90-day ED visits (EVs) and 30-day readmissions. RESULTS: A total of 4374 pediatric patients underwent GT placement. In this cohort, 6.1% and 11.4% had 30-day and 90-day EV; and 30-day readmissions in 19.75%. HLI was lower in those with 30-(244.6 ± 6.1 versus 245.4 ± 6.1; P = 0.0482) and 90-(244.5 ± 5.8 versus 245.5 ± 6.1; P = 0.001) day EV, and 30-day readmission (244.5 ± 5.56 versus 245.4 ± 6.1; P = 0.001) related to GT. ADI was lower in those with 90-day EV (55.1 ± 13.1 versus 55.9 ± 14.6; P = 0.0244). HLI was associated with decreased odds of 30- (adjusted odds ratio: 0.968; 95% confidence interval: 0.941-0.997) and 90-day (adjusted odds ratio: 0.975; 95% confidence interval: 0.954-0.998) EV following GT placement. ADI was also significantly associated with 30 and 90-day EV following GT placement. CONCLUSIONS: In pediatric patients undergoing GT placement, higher ecologically-measured health literacy and neighborhood socioeconomic disadvantage are associated with decreased health-care resource utilization, as evidenced by decreased ED visits. Future studies should focus on the role of individual parental health literacy in outcomes of pediatric surgical patients.

INTRODUCTION: Patients with pectus excavatum (PE) often undergo cross-sectional imaging (CSI) to quantify severity for insurance authorization before surgical repair. The modified percent depth (MPD), an external caliper-based metric, was previously validated to be similar to the pectus index and correction index. This study explored family perceptions of CSI and MPD with respect to value and costs. METHODS: This is a cross-sectional survey study including families of patients enrolled in an ongoing prospective multicenter study evaluating the use of MPD as an alternative to CSI for quantifying PE severity. Families of PE patients who underwent both MPD and CSI completed a survey to determine their perceptions of MPD and costs of CSI. Responses were described and associations were evaluated using chi squared, Wilcoxon rank-sum test and logistic regression as appropriate. Statistical significance was set to 0.05. RESULTS: There were 136 surveys completed for a response rate of 88%. Respondents were confident in MPD (86%) and confident in its similarity to CSI (76%). Families of females were less confident in the measurements than males (55% versus 80%, P = 0.02; odds ratio 0.30 (0.11, 0.83). Obtaining CSI required time off work/school in 90% and a copay in 60%. Nearly half (49%) of respondents reported CSI was a time/financial hardship. Increasing copay led to decreased reassurance in CSI (55%: copay > $100 versus 77%: lower copay/75%: no copay; P = 0.04). CONCLUSIONS: From the family perspective, MPD is valuable in assessing the severity of PE. Obtaining CSI was financially burdensome, particularly for those with higher copays. MPD measurements provide high value at low cost in assessing the severity of PE.
RESUMO
OBJECTIVE: To compare rates of postoperative drainage and culture profiles in children with complicated appendicitis treated with the two most common antibiotic regimens with and without antipseudomonal activity (piperacillin-tazobactam [PT] and ceftriaxone with metronidazole [CM]). SUMMARY OF BACKGROUND DATA: Variation in use of antipseudomonal antibiotics has been driven by a paucity of multicenter data reporting clinically relevant, culture-based outcomes. METHODS: Retrospective cohort study of patients with complicated appendicitis (7/2015-6/2020) using NSQIP-Pediatric data from 15 hospitals participating in a regional research consortium. Operative report details, antibiotic utilization, and culture data were obtained through supplemental chart review. Rates of 30-day postoperative drainage and organism-specific culture positivity were compared between groups using mixed effects regression to adjust for clustering after propensity matching on measures of disease severity. RESULTS: 1002 children met criteria for matching (58.9% received CM and 41.1% received PT). In the matched sample of 778 patients, children treated with PT had similar rates of drainage overall (PT: 11.8%, CM: 12.1%; OR 1.44 [OR:0.71-2.94]) and higher rates of drainage associated with growth of any organism (PT: 7.7%, CM: 4.6%; OR 2.41 [95%CI:1.08-5.39]) and Escherichia coli (PT: 4.6%, CM: 1.8%; OR 3.42 [95%CI:1.07-10.92]) compared to treatment with CM. Rates were similar between groups for drainage associated with multiple organisms (PT: 2.6%, CM: 1.5%; OR 3.81 [95%CI:0.96-15.08]) and Pseudomonas (PT: 1.0%, CM: 1.3%; OR 3.42 [95%CI:0.55-21.28]). CONCLUSIONS AND RELEVANCE: Use of antipseudomonal antibiotics is not associated with lower rates of postoperative drainage procedures or more favorable culture profiles in children with complicated appendicitis.
RESUMO
BACKGROUND: Nonaccidental trauma (NAT) affects >100,000 children in the United States every year and is associated with significant mortality and morbidity. Little is known about the financial burden of NAT, particularly in comparison to accidental trauma (AT). We sought to compare hospital charges and outcomes between children presenting with NAT and AT. METHODS: Pediatric (<16 y) trauma hospitalizations from 2006 to 2018 were identified using the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS) and Kid's Inpatient Sample (KID) databases. Hospitalizations were identified as NAT or AT based on ICD codes. Discharge weights were used to obtain national estimates and standardize them across the different sampling structures. Outcomes (hospital charges, length of stay (LOS), and mortality) were compared, and multivariate regression analyses were used to assess independent predictors of hospital charges and mortality. RESULTS: Fifty-eight Thousand Two Hundred Seventy-five pediatric hospitalizations were included with 17,954 (0.3%) categorized as NAT. Children with NAT were younger, more female, less likely to identify as White, and more under public insurance than those with AT. Hospital charges were significantly higher in patients with NAT ($27,100 versus $19,900, P < 0.0001). Mortality (4.9% versus 0.0%, P < 0.0001) and LOS (3.2 d versus 1.5 d, P < 0.0001) were significantly higher among patients with NAT. Multivariable regression analyses identified NAT as a predictor of higher hospital charges, mortality, and LOS. CONCLUSIONS: Nonaccidental trauma in pediatric patients is associated with significantly higher hospital charges, mortality, and LOS than accidental trauma. Ongoing research focused on the relative impact of known risk factors and resource utilization is needed.

INTRODUCTION: The delivery of pediatric surgical care for acute appendicitis involves general surgeons (GS) and pediatric surgeons (PS), but the differences in clinical practice are primarily undescribed. We examined charge differences between GS and PS for the treatment of pediatric acute appendicitis. METHODS: We performed a retrospective review of the North Carolina hospital discharge database (2013-2017) in pediatric patients (≤18 y) who had surgery for appendiceal pathology (acute or chronic appendicitis and other appendiceal pathology). We performed a bivariate analysis of surgical charges over the type of surgical providers (GS, PS, other specialty, and unassigned surgeons). RESULTS: Over the study period, 21,049 patients had appendicitis or other diseases of the appendix, and 15,230 (72.4%) underwent appendectomy. Patients who were operated on by PS were younger (10 y, interquartile range (IQR): 6-13 versus 13 y, IQR: 9-16, P < 0.001). Acute appendicitis was diagnosed in 2860 (44.3%) and 3173 (49.2%) of the PS and GS cohorts, respectively, P = 0.008. PS compared to GS performed a higher percentage of laparoscopic (n = 2,697, 89.4% versus n = 2,178, 65.5%) than open appendectomies (n = 280, 9.3% versus n = 1,118, 33.6%), P < 0.001. The overall hospital charges were $28,081 (IQR: $21,706-$37,431) and $24,322 (IQR: $17,906-$32,226) for PS and GS, respectively, P < 0.001. Surgical charges where higher for PS than GS, $12,566 (IQR: $9802-$17,462) and $8051 (IQR: $5872-$2331), respectively. When controlling for diagnosis, surgical approach, emergent status, age, and surgical cost of appendiceal surgery, and hospital charges following appendiceal surgery were $4280 higher for PS than GS (95% CI: 3874-4687). CONCLUSIONS: The total charge for operations for appendiceal disease is significantly higher for PS compared to GS. Pediatric surgeons had increased surgical charges compared to GS but decreased radiology charges. The specific reasons for these differences are not clearly delineated in this data set and persist after controlling for relevant covariates. However, these data demonstrate that increasing value in pediatric appendicitis may require specialty-based targets.

OBJECTIVE: The aim of this study was to define the training background of the actual surgical workforce providing care to pediatric patients in North Carolina (NC). BACKGROUND: Due to database limitations, pediatric surgical workforce studies have not included general surgeons (GS) who operate on children. Defining the role of GS in care delivery affects policy for clinical care and general and pediatric surgical training. METHODS: We performed a retrospective review of the NC Hospital Discharge Database (2011-2017), including pediatric patients (<18 years) undergoing the most frequent general surgery procedures. Descriptive and correlational analysis over surgical provider [Pediatric Surgeon (PS), GS], and other specialties (OSS), was performed using logistic regression modeling to identify factors associated with surgery by a PS. RESULTS: Of the 57,265 discharges analyzed, pediatric, general, and other specialty surgeons operated on 25,514 (44.6%), 18,581 (32.5%), and 9049 (15.8%), respectively. In a logistic regression model, PS had lower odds of operating on older patients [odds ratio (OR) 0.9, 95% confidence interval (CI) 0.90-0.91]. However, PS were more likely to operate on female patients (OR 1.58, 95% CI 1.53-1.65), Black (OR 1.49, 95% CI 1.43-1.56), and other minority patients (OR 1.23, 95% CI 1.17-1.29) when compared to white patients. PS were also more likely to operate on patients with private insurance (OR 1.38, 95% CI 1.33-1.43) compared to government insurance, and patients undergoing emergency surgery (OR 1.44, 95% CI 1.38-1.50). CONCLUSION: In NC, general surgeons performed a third of the operations on children. After controlling for covariates, pediatric surgeons in NC are more likely to operate on minority and emergency surgery patients, and this is the first study to describe this important practice pattern.

Congenital diaphragmatic hernia (CDH)-related deaths are the largest contributor to in-hospital neonatal deaths in children with congenital malformations. Morbidity and mortality in CDH are directly related to the development of pulmonary hypertension (PH). Current treatment consists of supportive measures. To date, no pharmacotherapy has been shown to effectively reverse the hallmark finding of pulmonary vascular remodeling that is associated with pulmonary hypertension in CDH (CDH-PH). As such, there is a great need for novel therapies to effectively manage CDH-PH. Our review aims to evaluate emerging therapies, and specifically focuses on those that are still under investigation and not approved for clinical use by the Food and Drug Administration. Therapies were categorized into antenatal pharmacotherapies or antenatal regenerative therapies and assessed on their method of administration, safety profile, the effect on pulmonary vascular pathophysiology, and overall efficacy. In general, emerging antenatal pharmaceutical and regenerative treatments primarily aim to alleviate pulmonary vascular remodeling by restoring normal function and levels of key regulatory factors involved in pulmonary vascular development and/or in promoting angiogenesis. Overall, while these emerging therapies show great promise for the management of CDH-PH, most require further assessment of safety and efficacy in preclinical models before translation into the clinical setting. IMPACT: Emerging antenatal therapies for congenital diaphragmatic hernia-induced pulmonary hypertension (CDH-PH) show promise to effectively mitigate vascular remodeling in preclinical models. Further investigation is needed in preclinical and human studies to evaluate safety and efficacy prior to translation into the clinical arena. This review offers a comprehensive and up-to-date summary of emerging therapies currently under investigation in experimental animal models. There is no cure for CDH-PH. This review explores emerging therapeutic options for the treatment of CDH-PH and evaluates their impact on key molecular pathways and clinical markers of disease to determine efficacy in the preclinical stage.

BACKGROUND: The Slit-Robo pathway is a key regulator of angiogenesis and cellular function in experimental models. Slit3 proteins exhibit both proangiogenic and antiangiogenic properties, but the exact mechanism remains unclear. It is theorized that Slit3 may be a potential treatment for vascular diseases and cancer. METHODS: Slit3 labeled with I-125 was encapsulated in microbeads composed of low-viscosity alginate of high-glucuronic acid content, first coated with poly-L-ornithine for various durations and finally with low-viscosity high mannuronic acid. Gamma counter was used to measure microbead encapsulation efficiency and Slit3 release. Markers of angiogenesis were assessed with Boyden chamber, scratch wound, and Matrigel tube formation assays using human umbilical vein and mouse endothelial cells. RESULTS: On incubation of Slit3-loaded microbeads, there was an initial burst phase release of Slit3 for the first 24 h followed by sustained release for 6 to 12 d. Microbead composition determined encapsulation efficiency and rate of release; Slit3 encapsulation was most efficient in microbeads with lower low-viscosity alginate of high-glucuronic acid content concentrations (1.5%) and no poly-L-ornithine coating. Compared with controls (media alone), Slit3 microbeads significantly inhibited in vitro cellular migration, endothelial cell migration for wound closure at 24 and 48 h and endothelial tube formation (P < 0.001, respectively). CONCLUSIONS: Slit3 can be effectively encapsulated and delivered via a controlled release pattern using alginate microbeads. Microbead encapsulation reduces in vitro endothelial tube formation and inhibits cellular migration to impair angiogenesis. Thus, Slit3 microparticles may be explored as a therapeutic option to mitigate tumor proliferation.

PURPOSE: Pediatric repair of chest wall deformities is associated with significant pain, morbidity, and resource utilization. We sought to determine outcomes of a perioperative enhanced recovery after surgery (ERAS) pathway for patients undergoing minimally invasive (Nuss) and traditional (Ravitch) corrective procedures. METHODS: Our ERAS protocol was implemented in 2015. We performed a retrospective review of patients for Nuss or Ravitch procedures before and after ERAS implementation. Combined and procedure segregated bivariate analyses were conducted on postoperative outcomes and resource utilization. RESULTS: There are 17 patients in the pre-intervention group (Nuss = 13 and Ravitch = 4) compared to 38 patients in the post-intervention group (Nuss = 28 and Ravitch = 10). Protocol implementation increased utilization of pre-operative non-narcotic medication. The combined and Nuss post-intervention groups had a significant decrease in epidural duration and time to enteral medications, but had increased total postoperative opioid usage. The Ravitch post-intervention group had a significant decrease in intra-operative narcotics and discharge pain scores. There were no differences in length of stay or complications. CONCLUSION: Implementation of our ERAS protocol standardized pectus perioperative care, but did not improve postoperative opioid usage, complications, or resource utilization. Alterations in the protocol may lead to achieving desired goals of better pain management and decreased resource utilization.

BACKGROUND: Congenital diaphragmatic hernia (CDH) is a structural birth defect associated with pulmonary hypoplasia and pulmonary arterial hypertension (PAH). We hypothesize that echocardiography provides a method to assess real-time right ventricle (RV) function, remodeling, and pulmonary artery (PA) flow. MATERIALS AND METHODS: Slit3 wild-type (WT) (n = 6) and knockout (KO) (n = 5) mice were analyzed at 2-3 months of age. Mice were anesthetized using isoflurane. Echocardiography was performed to analyze left and right ventricular wall thickness, internal diameter (ID), and function. Color Doppler was used to analyze flow in the PA and across the tricuspid valve. RESULTS: There was significant RV dilation in the KO mice versus WT, with an average RVID of 1.99 mm versus 1.26 mm, respectively (P = 0.007). Flow in the PA of KO mice was altered compared to WT, with elevated PA velocity time indices, 30.68 mm versus 22.13 mm (P = 0.012), elevated PA peak velocities, 952.61 mm/s versus 628.73 mm/s (P = 0.003), and decreased pulmonary acceleration times, 8.94 ms versus 16.18 ms (P = 0.002), respectively. Pulmonary vascular resistance, calculated by measuring tricuspid regurgitation peak velocity and right ventricular outflow tract velocity time index, was increased in KO versus WT mice, 17.61 mm2/s versus 8.91 mm2/s (P = 0.003), respectively. CONCLUSIONS: Slit3 KO mice with CDH show evidence of PAH and resultant RV dilation. Using direct cardiac puncture, elevated RV systolic pressures have been demonstrated in KO mice as evidence of PAH. Echocardiography allows direct analysis of the PA and real-time RV function without sacrifice of the mouse. This mode of evaluation allows longitudinal study in mice with PAH and CDH.

BACKGROUND: Significant mortality and morbidity are associated with alterations in the pulmonary vasculature. While techniques have been described for quantitative morphometry of whole-lung arterial trees in larger animals, no methods have been described in mice. We report a method for the quantitative assessment of murine pulmonary arterial vasculature using high-resolution computed tomography scanning. METHODS: Mice were harvested at 2 weeks, 4 weeks, and 3 months of age. The pulmonary artery vascular tree was pressure perfused to maximal dilation with a radio-opaque casting material with viscosity and pressure set to prevent capillary transit and venous filling. The lungs were fixed and scanned on a specimen computed tomography scanner at 8-µm resolution, and the vessels were segmented. Vessels were grouped into categories based on lumen diameter and branch generation. RESULTS: Robust high-resolution segmentation was achieved, permitting detailed quantitation of pulmonary vascular morphometrics. As expected, postnatal lung development was associated with progressive increase in small-vessel number and arterial branching complexity. CONCLUSIONS: These methods for quantitative analysis of the pulmonary vasculature in postnatal and adult mice provide a useful tool for the evaluation of mouse models of disease that affect the pulmonary vasculature.

PURPOSE: Congenital diaphragmatic hernia (CDH) involves lung hypoplasia and pulmonary hypertension (PH). Post-natal Perflubron ventilation induces lung growth. This phenomenon is called Perflubon-induced lung growth (PILG). However, it does not appear to ameliorate PH in CDH. We aim to determine the effect of PILG on pulmonary vascular remodeling in neonates with CDH and PH requiring extracorporeal membrane oxygenation (ECMO). METHODS: Lung tissue from four patients was obtained, three treated with PILG + ECMO, and one maintained on conventional ventilation + ECMO (control). The distribution of collagen was assessed with Masson's trichrome stain. Immunohistochemistry was done to assess cell proliferation and immunofluorescence to assess vascular morphology. RESULTS: Comparing PILG vs. control, there was an increase in vessel wall diameter (6.85 µm, 10.28 µm, and 10.35 µm vs. 4.34 µm), increase in collagen thickness in two PILG patients (35.66 µm, 14.23 µm, and 38.46 µm vs. 22.16 µm), and decrease in lumen diameter despite similar total area (48.99 µm, 41.74 µm, and 36.32 µm vs. 51.56 µm) for each PILG patient vs. the control patient, respectively. CONCLUSION: PILG does not appear to improve pulmonary vascular remodeling that occurs with PH. The findings are descriptive and will require larger samples to validate the significance of the findings. Overall, further studies will be required to identify the mechanistic causes of PH in CDH to create effective treatments.

BACKGROUND: Critically ill pediatric patients frequently require hemoglobin monitoring. Accurate noninvasive Hb (SpHb) would allow practitioners to decrease anemia from repeated blood draws, traumatic blood draws, and a decreased number of laboratory Hb (LabHb) medical tests. The Food and Drug Administration has approved the Masimo Pronto SpHb and associated Rainbow probes; however, its use in the pediatric intensive care unit (PICU) is controversial. In this study, we define the degree of agreement between LabHb and SpHb using the Masimo Pronto SpHb Monitor and identify clinical and demographic conditions associated with decreased accuracy. MATERIALS AND METHODS: We performed a prospective, observational study in a large PICU at an academic medical center. Fifty-three pediatric patients (30-d and 18-y-old), weighing >3 kg, admitted to the PICU from January-April 2013 were examined. SpHb levels measured at the time of LabHb blood draw were compared and analyzed. RESULTS: Only 83 SpHb readings were obtained in 118 attempts (70.3%) and 35 readings provided a result of "unable to obtain." The mean LabHb and SpHb were 11.1 g/dL and 11.2 g/dL, respectively. Bland-Altman analysis showed a mean difference of 0.07 g/dL with a standard deviation of ±2.59 g/dL. Pearson correlation is 0.55, with a 95% confidence interval between 0.38 and 0.68. Logistic regression showed that extreme LabHb values, increasing skin pigmentation, and increasing body mass index were predictors of poor agreement between SpHb and LabHb (P < 0.05). Separately, increasing body mass index, hypoxia, and hypothermia were predictors for undetectable readings (P < 0.05). CONCLUSIONS: The Masimo Pronto SpHb Monitor provides adequate agreement for the trending of hemoglobin levels in critically ill pediatric patients. However, the degree of agreement is insufficient to be used as the sole indicator for transfusion decisions and should be used in context of other clinical parameters to determine the need for LabHb in critically ill pediatric patients.

BACKGROUND: One of the objectives of the Millennium Development Goals is to improve child health. We describe the burden of pediatric surgical disease at a tertiary hospital in Malawi. METHODS: We conducted a retrospective analysis of a pediatric surgery database at Kamuzu Central Hospital in Malawi for the calendar year 2012. Variables included patient demographics, admission diagnosis, primary surgery and outcome. RESULTS: A total of 1170 pediatric patients aged 0-17 years were admitted to the surgical service during the study period. The mean age was 6.9 years, and 62% were male. Trauma was the most common indication for admission (51%, n = 596), and 67% (n = 779) of all patients were managed non-operatively. Neonates and patients managed non-operatively had a significantly increased risk of mortality. CONCLUSION: Only a third of patients admitted to the pediatric surgery service underwent surgery. More than half of patients with congenital anomalies did not undergo surgical intervention. Importantly, patients who underwent surgery had a survival advantage.

BACKGROUND: Pulmonary hypertension (PHTN) causes significant morbidity and mortality in patients with congenital diaphragmatic hernia (CDH). Currently, there is no routinely obtained prenatal prognostic marker to reliably predict postnatal CDH-associated PHTN severity. METHODS: The CDH Study Group (CDHSG) registry was queried for infants born from 2015 to 2021 with a graded (1-4) PHTN diagnosis. Fetal observed-to-expected lung volume to head circumference ratio (o/e LHR), percent predicted lung volume (PPLV), and total lung volume (TLV) were classified by severity. RESULTS: Of 4056 patients, 1047 and 785 infants had prenatal ultrasound or magnetic resonance imaging, respectively. Both moderate and severe o/e LHR were associated with increased odds of postnatal development of moderate (OR 2.913) and severe PHTN (OR 4.924). CONCLUSIONS: In infants with CDH, prenatal predictor severity was associated with higher severity of PHTN and increased ECLS usage. Overall, patients with worse prenatal prognostic indicators were less likely to receive pulmonary vasodilator treatment.
RESUMO
BACKGROUND: Central venous line (CVL) placement in children is often necessary for treatment and may be complicated by central line-associated bloodstream infection (CLABSI). We hypothesize that line type and clinical and demographic factors at line placement impact CLABSI rates. METHODS: This is a single-institution case-control study of pediatric patients (≤18 years old) admitted between January 1, 2015, and December 31, 2019. Case patients had a documented CLABSI. Control patients had a CVL placed during the study period and were matched by sex and age in a 2:1 ratio. Bivariate and multivariate logistic regression analysis was performed. RESULTS: We identified 78 patients with a CLABSI and 140 patients without a CLABSI. After controlling for pertinent covariates, patients undergoing tunneled or non-tunneled CVL had higher odds of CLABSI than those undergoing PICC (OR 2.51, CI 1.12-5.64 and OR 3.88, CI 1.06-14.20 respectively), and patients undergoing port placement had decreased odds of CLABSI compared to PICC (OR .05, CI 0.01-.51). There were lower odds of CLABSI when lines were placed for intravenous medications compared to those placed for solid tumor malignancy (OR .15, CI .03-.79). Race and age were not statistically significant risk factors. DISCUSSION: Central lines placed for medication administration compared to solid tumors, PICC compared to tunneled and non-tunneled central lines, and ports compared to PICC were associated with lower odds of CLABSI. Future improvement efforts should focus on PICC and port placement in appropriate patients to decrease CLABSI rates.

INTRODUCTION: Pediatric burns are associated with socioeconomic disadvantage and lead to significant morbidity. The Child Opportunity Index (COI) is a well-validated measure of neighborhood characteristics associated with healthy child development. We sought to evaluate the relationship between COI and outcomes of burn injuries in children. METHODS: We performed a single-institution retrospective review of pediatric (<16 years) burn admissions between 2015 and 2019. Based on United States residential zip codes, patients were stratified into national COI quintiles. We performed a multivariate Poisson regression analysis to determine the association between COI and increased length of stay. RESULTS: 2095 pediatric burn admissions occurred over the study period. Most children admitted were from very low (n = 644, 33.2 %) and low (n = 566, 29.2 %) COI neighborhoods. The proportion of non-Hispanic Black patients was significantly higher in neighborhoods with very low (44.5 %) compared to others (low:28.8 % vs. moderate:11.9 % vs. high:10.5 % vs. very high:4.3 %) (p < 0.01). Hospital length of stay was significantly longer in patients from very low COI neighborhoods (3.6 ± 4.1 vs. 3.2 ± 4.9 vs. 3.3 ± 4.8 vs. 2.8 ± 3.5 vs. 3.2 ± 8.1) (p = 0.02). On multivariate regression analysis, living in very high COI neighborhoods was associated with significantly decreased hospital length of stay (IRR: 0.51; 95 % CI: 0.45-0.56). CONCLUSION: Children from neighborhoods with significant socioeconomic disadvantage, as measured by the Child Opportunity Index, had a significantly higher incidence of burn injuries resulting in hospital admissions and longer hospital length of stay. Public health interventions focused on neighborhood-level drivers of childhood development are needed to decrease the incidence and reduce hospital costs in pediatric burns. TYPE OF STUDY: Retrospective study LEVEL OF EVIDENCE: Level III.

Importance: Gangrenous, suppurative, and exudative (GSE) findings have been associated with increased surgical site infection (SSI) risk and resource use in children with nonperforated appendicitis. Establishing the role for postoperative antibiotics may have important implications for infection prevention and antimicrobial stewardship. Objective: To compare SSI rates in children with nonperforated appendicitis with GSE findings who did and did not receive postoperative antibiotics. Design, Setting, and Participants: This was a retrospective cohort study using American College of Surgeons' National Surgical Quality Improvement Program (NSQIP)-Pediatric Appendectomy Targeted data from 16 hospitals participating in a regional research consortium. NSQIP data were augmented with operative report and antibiotic use data obtained through supplemental medical record review. Children with nonperforated appendicitis with GSE findings who underwent appendectomy between July 1, 2015, and June 30, 2020, were identified using previously validated intraoperative criteria. Data were analyzed from October 2022 to July 2023. Exposure: Continuation of antibiotics after appendectomy. Main Outcomes and Measures: Rate of 30-day postoperative SSI including both incisional and organ space infections. Complementary hospital and patient-level analyses were conducted to explore the association between postoperative antibiotic use and severity-adjusted outcomes. The hospital-level analysis explored the correlation between postoperative antibiotic use and observed to expected (O/E) SSI rate ratios after adjusting for differences in disease severity (presence of gangrene and postoperative length of stay) among hospital populations. In the patient-level analysis, propensity score matching was used to balance groups on disease severity, and outcomes were compared using mixed-effects logistic regression to adjust for hospital-level clustering. Results: A total of 958 children (mean [SD] age, 10.7 [3.7] years; 567 male [59.2%]) were included in the hospital-level analysis, of which 573 (59.8%) received postoperative antibiotics. No correlation was found between hospital-level SSI O/E ratios and postoperative antibiotic use when analyzed by either overall rate of use (hospital median, 53.6%; range, 31.6%-100%; Spearman ρ = -0.10; P = .71) or by postoperative antibiotic duration (hospital median, 1 day; range, 0-7 days; Spearman ρ = -0.07; P = .79). In the propensity-matched patient-level analysis including 404 patients, children who received postoperative antibiotics had similar rates of SSI compared with children who did not receive postoperative antibiotics (3 of 202 [1.5%] vs 4 of 202 [2.0%]; odds ratio, 0.75; 95% CI, 0.16-3.39; P = .70). Conclusions and Relevance: Use of postoperative antibiotics did not improve outcomes in children with nonperforated appendicitis with gangrenous, suppurative, or exudative findings.

BACKGROUND: Motor vehicle collision (MVC) is a leading cause of accidental death in children. Despite effective forms of child safety restraint (eg, car seat and booster seat), studies demonstrate poor compliance with guidelines. The goal of this study was to delineate injury patterns, imaging usage, and potential demographic disparities associated with child restraint use following MVC. METHODS: A retrospective review of the North Carolina Trauma Registry was performed to determine demographic factors and outcomes associated with improper restraint of children (0-8 years) involved in MVC from 2013 to 2018. Bivariate analysis was performed by the appropriateness of restraint. Multivariable Poisson regression identified demographic factors for the relative risk of inappropriate restraint. RESULTS: Inappropriately restrained patients were older (5.1 years v. 3.6 yrs, P < .001) and weighed more (44.1 lbs v. 35.3 lbs, P < .001). A higher proportion of African American (56.9% v. 39.3%, P < .001) and Medicaid (52.2% v. 39.0%, P < .001) patients were inappropriately restrained. Multivariable Poisson regression showed that African American patients (RR 1.43), Asian patients (RR 1.51), and Medicaid payor status (RR 1.25) were associated with a higher risk of inappropriate restraint. Inappropriately restrained patients had a longer length of stay, but injury severity score and mortality were no different. DISCUSSION: African American children, Asian children, and Medicaid insurance payor status patients had an increased risk of inappropriate restraint use in MVC. This study describes unequal restraint patterns in children, which suggests opportunity for targeted patient education and necessitates research to further delineate the underlying etiology of these differences.
