Utility of a Benchmarking Report for Balancing Infection Prevention and Antimicrobial Stewardship in Children with Complicated Appendicitis.

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.

Improving Accuracy of Administrative Data for Perforated Appendicitis Classification.

INTRODUCTION: Reliance on International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) diagnosis codes may misclassify perforated appendicitis with resultant research, fiscal, and public health implications. We aimed to improve the accuracy of administrative data for perforated appendicitis classification relying on ICD-10-CM codes from 2015 to 2018. METHODS: We conducted a retrospective study of randomly sampled patients aged ≤18 years diagnosed with acute appendicitis from eight children's hospitals. Patients were identified using the Pediatric Health Information System, and true perforation status was determined by medical record review. We developed two algorithms by leveraging Pediatric Health Information System data elements and data mining (DM) approaches. The two developed algorithm performance was compared against algorithms that exclusively relied on ICD-10-CM codes using area under the curve and other measures. RESULTS: Of 1051 clinically validated encounters that were included, 383 (36.4%) patients were identified to have perforated appendicitis. The two algorithms developed using DM approaches primarily leveraged ICD-10-CM codes and length of stay. DM-developed algorithms had a significantly higher accuracy than algorithms relying exclusively on ICD-10-CM (P value < 0.01): sensitivity and specificity for DM-developed algorithms were 0.86-0.88 and 0.95-0.97, respectively, which were overall higher than algorithms that relied on only ICD-10-CM. CONCLUSIONS: This study provides an algorithm that can improve the accuracy of perforated appendicitis classification using commonly available elements in administrative data. We recommend that this algorithm is used in future appendicitis classification to ensure valid reporting, hospital-level benchmarking, and fiscal or public health assessments.

Effect of Early vs Late Inguinal Hernia Repair on Serious Adverse Event Rates in Preterm Infants: A Randomized Clinical Trial.

Importance: Inguinal hernia repair in preterm infants is common and is associated with considerable morbidity. Whether the inguinal hernia should be repaired prior to or after discharge from the neonatal intensive care unit is controversial. Objective: To evaluate the safety of early vs late surgical repair for preterm infants with an inguinal hernia. Design, Setting, and Participants: A multicenter randomized clinical trial including preterm infants with inguinal hernia diagnosed during initial hospitalization was conducted between September 2013 and April 2021 at 39 US hospitals. Follow-up was completed on January 3, 2023. Interventions: In the early repair strategy, infants underwent inguinal hernia repair before neonatal intensive care unit discharge. In the late repair strategy, hernia repair was planned after discharge from the neonatal intensive care unit and when the infants were older than 55 weeks' postmenstrual age. Main Outcomes and Measures: The primary outcome was occurrence of any prespecified serious adverse event during the 10-month observation period (determined by a blinded adjudication committee). The secondary outcomes included the total number of days in the hospital during the 10-month observation period. Results: Among the 338 randomized infants (172 in the early repair group and 166 in the late repair group), 320 underwent operative repair (86% were male; 2% were Asian, 30% were Black, 16% were Hispanic, 59% were White, and race and ethnicity were unknown in 9% and 4%, respectively; the mean gestational age at birth was 26.6 weeks [SD, 2.8 weeks]; the mean postnatal age at enrollment was 12 weeks [SD, 5 weeks]). Among 308 infants (91%) with complete data (159 in the early repair group and 149 in the late repair group), 44 (28%) in the early repair group vs 27 (18%) in the late repair group had at least 1 serious adverse event (risk difference, -7.9% [95% credible interval, -16.9% to 0%]; 97% bayesian posterior probability of benefit with late repair). The median number of days in the hospital during the 10-month observation period was 19.0 days (IQR, 9.8 to 35.0 days) in the early repair group vs 16.0 days (IQR, 7.0 to 38.0 days) in the late repair group (82% posterior probability of benefit with late repair). In the prespecified subgroup analyses, the probability that late repair reduced the number of infants with at least 1 serious adverse event was higher in infants with a gestational age younger than 28 weeks and in those with bronchopulmonary dysplasia (99% probability of benefit in each subgroup). Conclusions and Relevance: Among preterm infants with inguinal hernia, the late repair strategy resulted in fewer infants having at least 1 serious adverse event. These findings support delaying inguinal hernia repair until after initial discharge from the neonatal intensive care unit. Trial Registration: ClinicalTrials.gov Identifier: NCT01678638.

Association of Prophylactic Antibiotics With Early Infectious Complications in Children With Cancer Undergoing Central Venous Access Device Placement.

OBJECTIVE: To evaluate the impact of prophylactic antibiotics on early infectious complications after central venous access device (VAD) placement in children with cancer. SUMMARY OF BACKGROUND DATA: Despite the frequency of VAD procedures in children, the effectiveness of prophylactic antibiotics for reducing infectious complications is unknown. METHODS: This was a retrospective cohort study of children with cancer undergoing central VAD placement identified in the Pediatric Health Information System database between 2017-2021. The primary outcome was the rate of early infectious complications (composite surgical site infections, central line-associated bloodstream infections, and bacteremia). Multivariable logistic regression was used to evaluate factors associated with early infection, and heterogeneity of treatment effect of prophylactic antibiotics was compared across subgroups. RESULTS: 9,216 patients were included (6,058 ports and 3,158 tunneled lines). Prophylactic antibiotics were associated with lower early infectious complications overall (1.3% vs. 2.4%; OR 0.55 [95% C.I. 0.39-0.79], P<0.001), an effect demonstrated for tunneled lines (OR 0.59, 95% C.I.: 0.41-0.84) but not ports (OR 3.01, 95% C.I.: 0.66-13.78). On multivariate analysis, prophylactic antibiotics (OR 0.67, 95% C.I.: 0.45-0.97) and solid tumors (OR 0.38, 95% C.I.: 0.22-0.64) were associated with reduced odds of early infections, while tunneled lines (OR 20.78, 95% C.I.: 9.83-43.93) and acute myelogenous leukemia (OR 2.37, 95% C.I.: 1.58-3.57) had increased odds. CONCLUSIONS: Prophylactic antibiotics are associated with reduced early infectious complications after central VAD placement overall. Despite recommendations from multiple national organizations against prophylactic antibiotics, these findings suggest a benefit in children with malignancy undergoing tunneled line placement.

Association Between Antibiotic Redosing Before Incision and Risk of Incisional Site Infection in Children With Appendicitis.

OBJECTIVE: To evaluate whether redosing antibiotics within an hour of incision is associated with a reduction in incisional surgical site infection (iSSI) in children with appendicitis. BACKGROUND: Existing data remain conflicting as to whether children with appendicitis receiving antibiotics at diagnosis benefit from antibiotic redosing before incision. METHODS: This was a multicenter retrospective cohort study using data from the Pediatric National Surgical Quality Improvement Program augmented with antibiotic utilization and operative report data obtained though supplemental chart review. Children undergoing appendectomy at 14 hospitals participating in the Eastern Pediatric Surgery Network from July 2016 to June 2020 who received antibiotics upon diagnosis of appendicitis between 1 and 6 hours before incision were included. Multivariable logistic regression was used to compare odds of iSSI in those who were and were not redosed with antibiotics within 1 hour of incision, adjusting for patient demographics, disease severity, antibiotic agents, and hospital-level clustering of events. RESULTS: A total of 3533 children from 14 hospitals were included. Overall, 46.5% were redosed (hospital range: 1.8%-94.4%, P <0.001) and iSSI rates were similar between groups [redosed: 1.2% vs non-redosed: 1.3%; odds ratio (OR) 0.84, (95%,CI, 0.39-1.83)]. In subgroup analyses, redosing was associated with lower iSSI rates when cefoxitin was used as the initial antibiotic (redosed: 1.0% vs nonredosed: 2.5%; OR: 0.38, (95% CI, 0.17-0.84)], but no benefit was found with other antibiotic regimens, longer periods between initial antibiotic administration and incision, or with increased disease severity. CONCLUSIONS: Redosing of antibiotics within 1 hour of incision in children who received their initial dose within 6 hours of incision was not associated with reduction in risk of incisional site infection unless cefoxitin was used as the initial antibiotic.

Use of Antipseudomonal Antibiotics is not Associated with Lower Rates of Postoperative Drainage Procedures or More Favorable Culture Profiles in Children with Complicated Appendicitis: Results from a Multicenter Regional Research Consortium.

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.

Generalizability of the Necrotizing Enterocolitis Surgery Trial to the Target Population of Eligible Infants.

OBJECTIVE: The objective of this study was to evaluate whether infants randomized in the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network Necrotizing Enterocolitis Surgery Trial differed from eligible infants and whether differences affected the generalizability of trial results. STUDY DESIGN: Secondary analysis of infants enrolled in Necrotizing Enterocolitis Surgery Trial (born 2010-2017, with follow-up through 2019) at 20 US academic medical centers and an observational data set of eligible infants through 2013. Infants born ≤1000 g and diagnosed with necrotizing enterocolitis or spontaneous intestinal perforation requiring surgical intervention at ≤8 weeks were eligible. The target population included trial-eligible infants (randomized and nonrandomized) born during the first half of the study with available detailed preoperative data. Using model-based weighting methods, we estimated the effect of initial laparotomy vs peritoneal drain had the target population been randomized. RESULTS: The trial included 308 randomized infants. The target population included 382 (156 randomized and 226 eligible, non-randomized) infants. Compared with the target population, fewer randomized infants had necrotizing enterocolitis (31% vs 47%) or died before discharge (27% vs 41%). However, incidence of the primary composite outcome, death or neurodevelopmental impairment, was similar (69% vs 72%). Effect estimates for initial laparotomy vs drain weighted to the target population were largely unchanged from the original trial after accounting for preoperative diagnosis of necrotizing enterocolitis (adjusted relative risk [95% CI]: 0.85 [0.71-1.03] in target population vs 0.81 [0.64-1.04] in trial) or spontaneous intestinal perforation (1.02 [0.79-1.30] vs 1.11 [0.95-1.31]). CONCLUSION: Despite differences between randomized and eligible infants, estimated treatment effects in the trial and target population were similar, supporting the generalizability of trial results. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT01029353.

Characteristics and predictors of intensive care unit admission in pediatric blunt abdominal trauma.

BACKGROUND: Pediatric trauma patients sustaining blunt abdominal trauma (BAT) with intra-abdominal injury (IAI) are frequently admitted to the intensive care unit (ICU). This study was performed to identify predictors for ICU admission following BAT. METHODS: Prospective study of children (< 16 years) who presented to 14 Level-One Pediatric Trauma Centers following BAT over a 1-year period. Patients were categorized as ICU or non-ICU patients. Data collected included vitals, physical exam findings, laboratory results, imaging, and traumatic injuries. A multivariable hierarchical logistic regression model was used to identify predictors of ICU admission. Predictive ability of the model was assessed via tenfold cross-validated area under the receiver operating characteristic curves (cvAUC). RESULTS: Included were 2,182 children with 21% (n = 463) admitted to the ICU. On univariate analysis, ICU patients were associated with abnormal age-adjusted shock index, increased injury severity scores (ISS), lower Glasgow coma scores (GCS), traumatic brain injury (TBI), and severe solid organ injury (SOI). With multivariable logistic regression, factors associated with ICU admission were severe trauma (ISS > 15), anemia (hematocrit < 30), severe TBI (GCS < 8), cervical spine injury, skull fracture, and severe solid organ injury. The cvAUC for the multivariable model was 0.91 (95% CI 0.88-0.92). CONCLUSION: Severe solid organ injury and traumatic brain injury, in association with multisystem trauma, appear to drive ICU admission in pediatric patients with BAT. These results may inform the design of a trauma bay prediction rule to assist in optimizing ICU resource utilization after BAT. STUDY DESIGN: Prognosis study.

Initial Laparotomy Versus Peritoneal Drainage in Extremely Low Birthweight Infants With Surgical Necrotizing Enterocolitis or Isolated Intestinal Perforation: A Multicenter Randomized Clinical Trial.

OBJECTIVE: The aim of this study was to determine which initial surgical treatment results in the lowest rate of death or neurodevelopmental impairment (NDI) in premature infants with necrotizing enterocolitis (NEC) or isolated intestinal perforation (IP). SUMMARY BACKGROUND DATA: The impact of initial laparotomy versus peritoneal drainage for NEC or IP on the rate of death or NDI in extremely low birth weight infants is unknown. METHODS: We conducted the largest feasible randomized trial in 20 US centers, comparing initial laparotomy versus peritoneal drainage. The primary outcome was a composite of death or NDI at 18 to 22 months corrected age, analyzed using prespecified frequentist and Bayesian approaches. RESULTS: Of 992 eligible infants, 310 were randomized and 96% had primary outcome assessed. Death or NDI occurred in 69% of infants in the laparotomy group versus 70% with drainage [adjusted relative risk (aRR) 1.0; 95% confidence interval (CI): 0.87-1.14]. A preplanned analysis identified an interaction between preoperative diagnosis and treatment group (P = 0.03). With a preoperative diagnosis of NEC, death or NDI occurred in 69% after laparotomy versus 85% with drainage (aRR 0.81; 95% CI: 0.64-1.04). The Bayesian posterior probability that laparotomy was beneficial (risk difference <0) for a preoperative diagnosis of NEC was 97%. For preoperative diagnosis of IP, death or NDI occurred in 69% after laparotomy versus 63% with drainage (aRR, 1.11; 95% CI: 0.95-1.31); Bayesian probability of benefit with laparotomy = 18%. CONCLUSIONS: There was no overall difference in death or NDI rates at 18 to 22 months corrected age between initial laparotomy versus drainage. However, the preoperative diagnosis of NEC or IP modified the impact of initial treatment.

Variability in the evalution of pediatric blunt abdominal trauma.

PURPOSE: To describe the practice pattern for routine laboratory and imaging assessment of children following blunt abdominal trauma (BAT). METHODS: Children (age < 16 years) presenting to 14 pediatric trauma centers following BAT over a 1-year period were prospectively identified. Injury, demographic, routine laboratory and imaging utilization data were collected. Descriptive, comparative, and correlation analysis was performed. RESULTS: 2188 children with a median age of 8 (4,12) years were included and the median injury severity score was 5 (1,10). There were significant differences in activation status, injury severity, and mechanism across centers; however, there was no correlation of level of activation, injury severity, or severe mechanism with test utilization. Routine laboratory and imaging utilization for hematocrit, hepatic enzymes, pancreatic enzymes, base deficit urine microscopy, chest and pelvis X-ray, and abdominal computed tomography (CT) varied significantly among centers. Only obtaining a hematocrit had a moderate correlation with CT use. There was no correlation between centers that were high or low frequency laboratory utilizers with CT use. CONCLUSIONS: Wide variability exists in the routine initial laboratory and imaging assessment in children following BAT. This represents an opportunity for quality improvement in pediatric trauma. LEVEL OF EVIDENCE: Level II.

Measuring the Value of a Clinical Practice Guideline for Children With Perforated Appendicitis.

OBJECTIVE: To determine the incremental cost-effectiveness of a clinical practice guideline (CPG) compared with "usual care" for treatment of perforated appendicitis in children. Secondary objective was to compare cost analyses using hospital accounting system data versus data in the Pediatric Health Information System (PHIS). BACKGROUND: Value-based surgical care (outcomes relative to costs) is frequently touted, but outcomes and costs are rarely measured together. METHODS: During an 18-month period, 122 children with perforated appendicitis at a tertiary referral children's hospital were treated using an evidence-based CPG. Clinical outcomes and costs for the CPG cohort were compared with patients in the 30-month period before CPG implementation (n = 191 children). RESULTS: With CPG-directed care, intra-abdominal abscess rate decreased from 0.24 to 0.10 (adjusted risk ratio 0.44, 95% confidence interval [CI] 0.26-0.75). The rate of any adverse event decreased from 0.30 to 0.23 (adjusted risk ratio 0.82, 95% CI 0.58-1.17). Mean total hospital costs per patient (hospital accounting system) decreased from $16,466 to $10,528 (adjusted absolute difference-$5451, 95% CI -$7755 to -$3147), leading to estimated adjusted total savings of $665,022 during the study period. Costs obtained from the PHIS database also showed reduction with CPG-directed care (-$6669, 95% CI -$8949 to -$4389 per patient). In Bayesian cost-effectiveness analyses, likelihood that CPG was the dominant strategy was 91%. CONCLUSIONS: An evidence-based CPG increased the value of surgical care for children with perforated appendicitis by improving outcomes and lowering costs. Hospital cost accounting data and pre-existing cost data within the PHIS database provided similar results.

Case Volume and Revisits in Children Undergoing Gastrostomy Tube Placement.

OBJECTIVES: Emergency department (ED) visits and hospital readmissions are common after gastrostomy tube (GT) placement in children. We sought to characterize interhospital variation in revisit rates and explore the association between this outcome and hospital-specific GT case volume. PATIENTS AND METHODS: We conducted a retrospective cohort study from 38 hospitals using the Pediatric Health Information System database. Patients younger than 18 years who had a GT placed in 2010 to 2012 were assessed for a GT-related (mechanical or infectious) ED visit or inpatient readmission at 30 and 90 days after discharge from GT placement. Risk-adjusted rates were calculated using generalized linear mixed-effects models accounting for hospital clustering and relevant demographic and clinical attributes, then compared across hospitals. RESULTS: A total of 15,642 patients were included. A median of 468 GTs were placed in all the 38 hospitals during 3 years (range: 83-891), with a median of 11.4 GT placed per 1000 discharges (range: 2.4-16.7). Median ED visit for each hospital at 30 days after discharge was 8.2% (range: 3.7%-17.2%) and 14.8% at 90 days (range: 6.3%-26.1%). Median inpatient readmissions for each hospital at 30 days after discharge was 3.5% (range: 0.5%-10.5%) and 5.9% at 90 days (range: 1.0%-18.5%). Hospital-specific GT placement per 1000 discharges (rate of GT placement) was inversely correlated with ED visit rates at 30 (P = 0.007) and 90 days (P = 0.020). The adjusted 30- and 90-day readmission rate and the adjusted 30- and 90-day ED return rates decreased with increasing GT insertion rate (P < 0.001). CONCLUSION: Higher hospital GT insertion rates are associated with lower ED revisit rates but not inpatient readmissions.

Emergency Department Visits and Readmissions among Children after Gastrostomy Tube Placement.

OBJECTIVES: To define the incidence of 30-day postdischarge emergency department (ED) visits and hospital readmissions following pediatric gastrostomy tube (GT) placement across all procedural services (Surgery, Interventional-Radiology, Gastroenterology) in 38 freestanding Children's Hospitals. STUDY DESIGN: This retrospective cohort study evaluated patients <18 years of age discharged between 2010 and 2012 after GT placement. Factors significantly associated with ED revisits and hospital readmissions within 30 days of hospital discharge were identified using multivariable logistic regression. A subgroup analysis was performed comparing patients having the GT placed on the date of admission or later in the hospital course. RESULTS: Of 15 642 identified patients, 8.6% had an ED visit within 30 days of hospital discharge, and 3.9% were readmitted through the ED with a GT-related issue. GT-related events associated with these visits included infection (27%), mechanical complication (22%), and replacement (19%). In multivariable analysis, Hispanic ethnicity, non-Hispanic black race, and the presence of ≥3 chronic conditions were independently associated with ED revisits; gastroesophageal reflux and not having a concomitant fundoplication at time of GT placement were independently associated with hospital readmission. Timing of GT placement (scheduled vs late) was not associated with either ED revisits or hospital readmission. CONCLUSIONS: GT placement is associated with high rates of ED revisits and hospital readmissions in the first 30 days after hospital discharge. The association of nonmodifiable risk factors such as race/ethnicity and medical complexity is an initial step toward understanding this population so that interventions can be developed to decrease these potentially preventable occurrences given their importance among accountable care organizations.

Enhancing recovery in pediatric surgery: a review of the literature.

BACKGROUND: Enhanced recovery after surgery (ERAS), guidelines entail a strategy of perioperative management proven to hasten postoperative recovery and reduce complications in adult populations. Relatively few studies have investigated the applicability of this paradigm to pediatric populations. Our objective was to perform a systematic review of existing evidence regarding the use and efficacy of enhanced recovery protocols (ERPs) in the pediatric population. MATERIALS AND METHODS: Data were collected through a PubMed/MEDLINE literature search. Study eligibility criteria included a pediatric population and implementation of at least four components of published ERAS Society recommendations. RESULTS: One retrospective and four prospective cohort studies evaluating children undergoing gastrointestinal, urologic, and thoracic surgeries were identified. The overall quality of reporting was fair with few studies acknowledging limitations and bias and inconsistent outcome reporting. Studies included six or fewer interventions compared to 20 recommended interventions in most adult ERAS Society guidelines. None of the studies were well controlled. Nevertheless, these studies suggest that ERPs applied to the appropriate pediatric surgical populations may be associated with decreased length of stay, decreased narcotic use, and no detectable increase in complications. CONCLUSIONS: There is a paucity of high-quality literature evaluating implementation of ERPs in pediatric populations. The limited literature available indicates that ERPs would be safe and potentially effective. More studies are needed to assess the efficacy of ERPs in pediatric surgery.

A systematic review and individual patient data meta-analysis of published randomized clinical trials comparing early versus interval appendectomy for children with perforated appendicitis.

PURPOSE: Our objective was to perform a meta-analysis on RCTs that compared outcomes in children with perforated appendicitis (PA) who underwent either early appendectomy (EA) or interval appendectomy (IA). We also sought to determine if the presence of an intra-abdominal abscess (IAA) at admission impacted treatment strategy and outcomes. METHODS: We identified two RCTs comparing EA versus IA in children with PA. A meta-analysis was performed using regression models and the overall adverse event rate was analyzed. The treatment effect variation depending on the presence of IAA at admission was also evaluated. RESULTS: EA significantly reduced the odds of an adverse event (OR 0.28, 95 % CI 0.1-0.77) and an unplanned readmission (OR 0.08, 95 % CI 0.01-0.67), as well as the total charges (79 % of the IA, 95 % CI 63-100) for those who did not have an IAA at admission. In children with an IAA, there was no difference between EA and IA. However, heterogeneity of treatment effect was present regarding IAA at presentation. CONCLUSIONS: While EA appears to improve outcomes in patients without an abscess, the published data support no significant difference in outcomes between EA and IA in patients with an abscess.

Clinical outcomes of splenectomy in children: report of the splenectomy in congenital hemolytic anemia registry.

The outcomes of children with congenital hemolytic anemia (CHA) undergoing total splenectomy (TS) or partial splenectomy (PS) remain unclear. In this study, we collected data from 100 children with CHA who underwent TS or PS from 2005 to 2013 at 16 sites in the Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium using a patient registry. We analyzed demographics and baseline clinical status, operative details, and outcomes at 4, 24, and 52 weeks after surgery. Results were summarized as hematologic outcomes, short-term adverse events (AEs) (≤30 days after surgery), and long-term AEs (31-365 days after surgery). For children with hereditary spherocytosis, after surgery there was an increase in hemoglobin (baseline 10.1 ± 1.8 g/dl, 52 week 12.8 ± 1.6 g/dl; mean ± SD), decrease in reticulocyte and bilirubin as well as control of symptoms. Children with sickle cell disease had control of clinical symptoms after surgery, but had no change in hematologic parameters. There was an 11% rate of short-term AEs and 11% rate of long-term AEs. As we accumulate more subjects and longer follow-up, use of a patient registry should enhance our capacity for clinical trials and engage all stakeholders in the decision-making process.

Postoperative Antibiotics, Outcomes, and Resource Use in Children With Gangrenous Appendicitis.

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.

Changes in hospital utilization and management of Hirschsprung disease: analysis using the kids' inpatient database.

OBJECTIVE: This study investigates how the epidemiology, hospital utilization, and surgical management of Hirschsprung disease (HD) have changed over the last decade in the United States, using a statistically valid national sample. BACKGROUND: HD is a congenital gastrointestinal disorder that requires surgical resection for correction. Some patients experience long-term bowel dysfunction requiring hospital care. Historically, patients had multiple staged operations, whereas more recently, single-stage laparoscopic resection and pull-through operations are more common. Assessment of possible changes over time in HD-associated complications requiring hospitalization and length of hospital stay has not been quantified epidemiologically. METHODS: The Kids' Inpatient Database was queried for all discharges with an International Classification of Disease, Ninth Revision, Clinical Modification code for HD in the years 1997, 2000, 2003, and 2006. The HD cohorts from these 4 time points were compared, specifically analyzing differences in demographic data, associated diagnoses, in-hospital mortality and length of stay, procedures performed during hospitalization, and frequency of hospitalizations for HD-associated complications. Results reported included estimated frequencies and means with 95% confidence intervals. RESULTS: The estimated numbers of HD discharges, associated demographic data, and numbers of pull-through procedures have remained stable over the decade. The mean age (years) at the time of pull-through has decreased from 1.45 to 1.16 to 1.18 to 0.97 (P = 0.01). The mean length of stay (days) for these procedures has increased from 8.40 to 8.46 to 9.25 to 10.55 (P = 0.002). The estimated numbers of hospital admissions for HD-related constipation increased in recent years from 395 to 340 to 536 to 566 (P = 0.001). The estimated numbers of admissions for enterocolitis suggest an increasing trend from 466 to 402 to 584 to 556 (P = 0.11). CONCLUSIONS: HD pull-through procedures are being performed at younger ages over time, and post-pull-through lengths of stay have increased. Admissions for some HD-related complications have increased over the decade. Prospective cohort studies are needed to determine whether causal relationships exist among these trends.
