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.

The Surgical Clerkship in the COVID Era: A Natural Language Processing and Thematic Analysis.

INTRODUCTION: Responses to COVID-19 within medical education prompted significant changes to the surgical clerkship. We analyzed the changes in medical student end of course feedback before and after the COVID-19 outbreak. METHODS: Postclerkship surveys from 2017 to 2022 were analyzed including both Likert scale data and free text, excluding the COVID outbreak year 2019-2020. Likert scale questions were compared between pre-COVID (2017-2019) and COVID-era cohorts (2020-2022) with the Mann-Whitney U-test. Free-text comments were analyzed using both thematic analysis and natural language processing including sentiment, word and phrase frequency, and topic modeling. RESULTS: Of the 483 medical students surveyed from 2017 to 2022, 297 responded (61% response rate) to the included end of clerkship surveys. Most medical students rated the clerkship above average or excellent with no significant difference between the pre-COVID and COVID-era cohorts (70.4% Versus 64.8%, P = 0.35). Perception of grading expectations did significantly differ, 51% of pre-COVID students reported clerkship grading standards were almost always clear compared to 27.5% of COVID-era students (P = 0.01). Pre-COVID cohorts more frequently mentioned learning and feedback while COVID-era cohorts more frequently mentioned case, attending, and expectation. Natural language processing topic modeling and formal thematic analysis identified similar themes: team, time, autonomy, and expectations. CONCLUSIONS: COVID-19 presented many challenges to undergraduate medical education. Despite many changes, there was no significant difference in clerkship satisfaction ratings. Unexpectedly, the greater freedom and autonomy of asynchronous lectures and choice of cases became a highlight of the new curriculum. Future research should investigate if there are similar associations nationally with a multi-institutional study.

Prior Teaching Experience and Barriers to Effective Resident Teaching: A Cross-Sectional Study.

INTRODUCTION: Resident physicians play an important role in teaching the next generation of health-care providers, yet limited research has explored factors influencing effective teaching, such as preresidency experiences or barriers within residency. This study examines residents' prior teaching experience, its correlation with teaching attitudes, and identifies potential barriers to sustained teaching engagement. METHODS: This cross-sectional study surveyed residents across multiple specialties at a single academic center. The survey assessed preresidency teaching experience, perceived barriers, and attitudes toward teaching. Univariate and multivariate analyses identified differences in teaching attitudes based on prior teaching experience and gender. RESULTS: Ninety-two residents across 11 specialties participated (52.2% female). Internal Medicine (28.3%) and General Surgery (26.1%) had the highest representation. Two-thirds of respondents (69.6%) had formal teaching experience before residency. After adjustment, prior teaching experience and male gender were associated with feeling prepared to teach medical students (P = 0.014 and P = 0.001). Male gender was also linked to confidence in teaching material on the wards (P = 0.015). Barriers identified included time constraints (73.9%), lack of content clarity (28.3%), and uncertainty about teaching methods (33.7%). CONCLUSIONS: Residents with prior teaching experience exhibit higher levels of preparedness, content clarity, and confidence in their teaching abilities, underscoring the importance of teaching experience before residency. This study also identified significant barriers to effective teaching, including time constraints, lack of content clarity, uncertainty about teaching methods, and perceived disinterest from medical students. Addressing these barriers is essential for optimizing medical student education.

Wilms tumor characteristics, surgical management, outcomes, and chronic kidney disease in children with WAGR syndrome: A report from the International WAGR Syndrome Association survey.

INTRODUCTION: Children with WAGR (Wilms tumor, aniridia, genitourinary anomalies, and range of development delays) syndrome are predisposed to Wilms tumor (WT) and intrinsic kidney disease. Using the comprehensive International WAGR Syndrome Association (IWSA) survey of children with WAGR syndrome, we analyzed tumor characteristics, treatment and congenital risk factors, and kidney function in children with WAGR and WT. METHODS: Descriptive statistics were utilized including demographics, treatment strategies, and patient outcomes. Comparisons were made between patients with WAGR and WT to those with WAGR alone. A multivariable logistic regression was completed for risk of developing WT and to identify predictors of chronic kidney disease (CKD). RESULTS: Sixty-four of 145 children with WAGR developed WT (44.1%). Three relapsed and one died. CKD developed in five children with WAGR without WT (5/81, 6.2%), and in 34 with WAGR and WT (34/64, 28.3%). Children with WAGR and WT were younger (p = .017), and had a greater association with CKD than WAGR children without WT (p < .0001). Two children with WT required hemodialysis, and one underwent kidney transplantation. By univariate analysis, CKD at any stage was associated with complete nephrectomy for the WT surgery (p < .0001), chemotherapy duration greater than 12 months, and three-drug therapy. Upon multivariate analysis, prior nephrectomy was the only significant variable (p = .0002). CONCLUSIONS: Epidemiological analysis of children with WAGR demonstrated favorable oncologic outcomes, but high rate of early CKD in those who developed WT. Further study of the use of nephron-sparing surgery in children with WAGR and strategies to delay or treat early CKD are needed.

Current surgical approaches to pediatric renal tumors.

Pediatric renal tumors are among the most common pediatric solid malignancies. Surgical resection is a key component in the multidisciplinary therapy for children with kidney tumors. Therefore, it is imperative that surgeons caring for children with renal tumors fully understand the current standards of care in order to provide appropriate surgical expertise within this multimodal framework. Fortunately, the last 60 years of international, multidisciplinary pediatric cancer cooperative group studies have enabled high rates of cure for these patients. This review will highlight the international surgical approaches to pediatric patients with kidney cancer to help surgeons understand the key differences and similarities between the European (International Society of Pediatric Oncology) and North American (Children's Oncology Group) recommendations.

Survival outcomes in pediatric patients with metastatic Ewing sarcoma who achieve a rapid complete response of pulmonary metastases.

PURPOSE: Our objectives were to compare overall survival (OS) and pulmonary relapse between patients with metastatic Ewing sarcoma (EWS) at diagnosis who achieve rapid complete response (RCR) and those with residual pulmonary nodules after induction chemotherapy (non-RCR). PATIENTS AND METHODS: This retrospective cohort study included children under 20 years with metastatic EWS treated from 2007 to 2020 at 19 institutions in the Pediatric Surgical Oncology Research Collaborative. Chi-square tests were conducted for differences among groups. Kaplan-Meier curves were generated for OS and pulmonary relapse. RESULTS: Among 148 patients with metastatic EWS at diagnosis, 61 (41.2%) achieved RCR. Five-year OS was 71.2% for patients who achieved RCR, and 50.2% for those without RCR (p = .04), and in multivariable regression among patients with isolated pulmonary metastases, RCR (hazards ratio [HR] 0.42; 95% confidence interval [CI]: 0.17-0.99) and whole lung irradiation (WLI) (HR 0.35; 95% CI: 0.16-0.77) were associated with improved survival. Pulmonary relapse occurred in 57 (37%) patients, including 18 (29%) in the RCR and 36 (41%) in the non-RCR groups (p = .14). Five-year pulmonary relapse rates did not significantly differ based on RCR (33.0%) versus non-RCR (47.0%, p = .13), or WLI (38.8%) versus no WLI (46.0%, p = .32). DISCUSSION: Patients with EWS who had isolated pulmonary metastases at diagnosis had improved OS if they achieved RCR and received WLI, despite having no significant differences in rates of pulmonary relapse.

Management of undifferentiated embryonal sarcoma of the liver: A Pediatric Surgical Oncology Research Collaborative study.

BACKGROUND: Undifferentiated embryonal sarcoma of the liver (UESL) is a rare tumor for which there are few evidence-based guidelines. The aim of this study was to define current management strategies and outcomes for these patients using a multi-institutional dataset curated by the Pediatric Surgical Oncology Research Collaborative. METHODS: Data were collected retrospectively for patients with UESL treated across 17 children's hospitals in North America from 1989 to 2019. Factors analyzed included patient and tumor characteristics, PRETEXT group, operative details, and neoadjuvant/adjuvant regimens. Event-free and overall survival (EFS, OS) were the primary and secondary outcomes, respectively. RESULTS: Seventy-eight patients were identified with a median age of 9.9 years [interquartile range [IQR): 7-12]. Twenty-seven patients underwent resection at diagnosis, and 47 patients underwent delayed resection, including eight liver transplants. Neoadjuvant chemotherapy led to a median change in maximum tumor diameter of 1.6 cm [IQR: 0.0-4.4] and greater than 90% tumor necrosis in 79% of the patients undergoing delayed resection. R0 resections were accomplished in 63 patients (81%). Univariate analysis found that metastatic disease impacted OS, and completeness of resection impacted both EFS and OS, while multivariate analysis revealed that R0 resection was associated with decreased expected hazards of experiencing an event [hazard ratio (HR): 0.14, 95% confidence interval (CI): 0.04-0.6]. At a median follow-up of 4 years [IQR: 2-8], the EFS was 70.0% [95% CI: 60%-82%] and OS was 83% [95% CI: 75%-93%]. CONCLUSION: Complete resection is associated with improved survival for patients with UESL. Neoadjuvant chemotherapy causes minimal radiographic response, but significant tumor necrosis.

Contemporary trends in choledochal cyst excision: An analysis of the pediatric national surgical quality improvement program.

BACKGROUND: Choledochal cysts are rare congenital anomalies of the biliary tree that may lead to obstruction, chronic inflammation, infection, and malignancy. There is wide variation in the timing of resection, operative approach, and reconstructive techniques. Outcomes have rarely been compared on a national level. METHODS: We queried the Pediatric National Surgical Quality Improvement Program (NSQIP) to identify patients who underwent choledochal cyst excision from 2015 to 2020. Patients were stratified by hepaticoduodenostomy (HD) versus Roux-en-Y hepaticojejunostomy (RNYHJ), use of minimally invasive surgery (MIS), and age at surgery. We collected several outcomes, including length of stay (LOS), reoperation, complications, blood transfusions, and readmission rate. We compared outcomes between cohorts using nonparametric tests and multivariate regression. RESULTS: Altogether, 407 patients met the study criteria, 150 (36.8%) underwent RNYHJ reconstruction, 100 (24.6%) underwent MIS only, and 111 (27.3%) were less than one year old. Patients who underwent open surgery were younger (median age 2.31 vs. 4.25 years, p = 0.002) and more likely underwent RNYHJ reconstruction (42.7% vs. 19%, p = 0.001). On adjusted analysis, the outcomes of LOS, reoperation, transfusion, and complications were similar between the type of reconstruction, operative approach, and age. Patients undergoing RNYHJ had lower rates of readmission than patients undergoing HD (4.0% vs. 10.5%, OR 0.34, CI [0.12, 0.79], p = 0.02). CONCLUSIONS: In children with choledochal cysts, most short-term outcomes were similar between reconstructive techniques, operative approach, and age at resection, although HD reconstruction was associated with a higher readmission rate in this study. Clinical decision-making should be driven by long-term and biliary-specific outcomes.

Pediatric urothelial cancer: a cross-sectional descriptive analysis of the National Cancer Database.

Background: Urothelial cancer is a rare pediatric malignancy; previous analyses suggest lower rates of recurrence and death as compared to adults. We analyzed pediatric bladder cancer information in a national database, hypothesizing that survival would be better in children than adults. Methods: We analyzed the 2004-2016 National Cancer Database (NCDB) for children and adolescents (0-18 years) with urothelial bladder cancer. Rhabdomyosarcoma patients were excluded. Assessed variables included TNM staging, pathology, tumor size, surgical procedures, and post-operative re-admissions. Overall survival was defined as months since diagnosis as of last follow-up. Results: Of 140 urothelial tumors reported to NCDB between 2004-2016, 75.7% (N=106) were stage 0 at diagnosis, 6.4% (N=9) were stage I, 2.9% (N=4) were stage II and 3.6% (N=5) were stage IV, while 11.4% cases (N=16) were unknown. From available mortality data (121 patients), no patients died after definitive surgical resection. Only 1 mortality was reported at 90 days, although cause of death was reportedly unknown. Three (2.5%) patients were lost to follow-up, and most (96.7%) were alive at 90 days. Conclusions: Short-term survival outcomes among children and adolescents with urothelial bladder tumors captured in NCDB are reassuring. Future investigations focused on long-term outcomes and appropriate surveillance in this rare patient cohort are imperative to better guide management options.

Who Benefits? An Assessment of Resident Benefits at Top 50 Academic Institutions.

OBJECTIVE: Residency serves as a crucial time in the professional and personal development of young physicians. Extensive effort is devoted to the clinical training of residents across the country. However, many residents report concerns with compensation, quality of life, and benefits during their clinical training. We sought to evaluate the benefits packages of resident physicians in comparison with other full-time employees at their institutions. SETTING: "Top 50" Residency programs in Medicine, Surgery, and Pediatrics in the United States. DESIGN: To accomplish this task we selected the, "Top-50," institutions for medicine, pediatrics, and surgery using Doximity's Residency Navigator and compared the benefits of residents at these institutions with full-time employees by accessing benefits offerings listed on institutional websites. RESULTS: We found that residents were more likely to receive parking benefits and gym memberships, while full-time employees were more likely to be offered flexible spending accounts, retirement benefits, and tuition support. CONCLUSIONS: Residents receive different benefits packages than their colleagues employed in full time positions at the same institutions. Further discussion regarding the benefits offered to physicians, and the role that benefits play in resident wellbeing is warranted in light of these findings.

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.
