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.

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.

Utilizing ultrasound in suspected necrotizing enterocolitis with equivocal radiographic findings.

BACKGROUND: To examine the use of abdominal ultrasound (AUS) as a diagnostic adjunct in the diagnosis of necrotizing enterocolitis (NEC) in cases where abdominal radiography (AXR) is equivocal in order to reduce unnecessary antibiotic use in neonates. METHODS: Retrospective study (2017-2019) of infants undergoing NEC evaluation with equivocal AXR findings (n = 54). Paired AXR and AUS were reviewed with respect to presence or absence of pneumatosis. Concordance of AUS findings with decision to treat for NEC was evaluated. RESULTS: Among 54 infants where AXR was equivocal, AUS demonstrated presence of pneumatosis in 22 patients (41%), absence of pneumatosis in 31 patients (57%), and was equivocal in 1 patient. All patients with pneumatosis on AUS were treated for NEC. Of 31 patients without pneumatosis on AUS, 25 patients (78%) were not treated for NEC. Patients without pneumatosis on AUS received a significantly shorter mean duration of antibiotics compared to those with pneumatosis (3.3 days (+/- 4.8 days) vs 12.4 days (+/- 4.7 days)); p < 0.001). Of those patients not treated, none required treatment within 1 week following negative AUS. CONCLUSION: AUS is a valuable tool for evaluating the presence or absence of pneumatosis in the setting of equivocal AXR. Absence of pneumatosis on AUS informs clinical decision making and reduces unnecessary treatment and antibiotic usage.

Operative Findings in Pediatric and Adolescent Patients With Presumed Adnexal Torsion.

INTRODUCTION: Clinical and radiographic findings often lead to diagnostic laparoscopy for presumed adnexal torsion (AT). To better understand the preoperative factors leading to AT, we evaluated the clinical course of patients with ultrasound findings concerning for AT to assess intraoperative AT rates and predictive factors for AT. METHODS: An institutional review board-approved retrospective review in two hospital centers over a period of 5 y was performed for females (4-18 y) with ultrasound (US) findings concerning for AT (n = 225). Preoperative clinical, radiographic, and intraoperative findings were assessed for patients with intraoperative AT versus for those without. RESULTS: The median age of patients was 14 y. Of those who went to the operating room (OR) (n = 113), AT was found in 57%. There was no difference between patients taken to the OR with or without AT regarding demographics or presentation. The presence of nausea/vomiting, tenderness, leukocytosis, lack of blood flow, or a mass/cyst >5 cm were found to be more likely in patients with AT than in those without. An ovarian volume ratio >15 was noted to be predictive of AT. Six patients initially discharged from the emergency department returned and went to the OR, two of which had AT, both with ovarian salvage. CONCLUSIONS: Limited data are available when counseling patients with presumed AT. We found the larger mean ovarian volume and an ovarian volume ratio >15 were predictive of AT. Despite this, 43% of patients taken to the OR did not have AT. This relatively high rate of not finding AT intraoperatively may be justified given the sequelae of missing AT.

Outcomes of Initial Subtotal Colectomy for Pediatric Inflammatory Bowel Disease.

BACKGROUND: Subtotal colectomy with end ileostomy (STC-I) has been well established in the adult literature as an initial surgical treatment for refractory inflammatory bowel disease (IBD)-related colitis. However, in the pediatric population, the efficacy of this approach has been less well characterized, likely because of concerns regarding the advisability of leaving a diseased rectum in situ. Our aim was to examine the outcomes after STC-I for refractory IBD at our pediatric tertiary care center. METHODS: An institutional review board-approved retrospective review of patients aged 5-21 y who underwent operative treatment with initial STC-I for medically refractory IBD from January 2010 to August 2018. Only complications related to the STC-I were considered; complications subsequent to reconstruction are excluded from analysis. Early complications were defined as occurring within 60 d of STC-I. We performed descriptive statistics using the Fisher exact test and the Student t-test, as appropriate. RESULTS: Over the study period, 37 patients (aged 12.3 ± 4.2 y) underwent STC-I, with 73.0% performed laparoscopically. Patients were predominately male (51.4%) and Caucasian (48.6%). Thirty-one (83.8%) colectomies were performed for ulcerative colitis, two (5.4%) for Crohn disease, and four (10.8%) for indeterminate colitis. Nutritional status improved postcolectomy. Albumin levels of 3.3 ± 0.8 preoperatively increased to 4.3 ± 0.47 postoperatively (P < 0.001). Colonic bleeding was stopped by STC-I with increases in the hematocrit from 30.5 ± 6.8 preoperative to 38.9 ± 4.1 postoperatively (P < 0.001). Average time to discontinuation of IBD-related medications was 4 wk (n = 27). Forty-eight percent required outpatient rectal treatment for proctitis. Patients did well long term, with 67.5% reestablishing intestinal continuity at our institution. Average postoperative length of stay was shorter in the laparoscopic group compared with those undergoing open operations (5.1 ± 2.2 versus 6.9 ± 1.6 d, P = 0.03). Readmission rate at 30 d was 21.1%. Patients experiencing unplanned readmission or unplanned operations were similar between groups (30% versus 33.3%, P = 0.85 and 30% versus 18.5%, P = 0.45, respectively). Overall, 14 (37.8%) patients experienced a complication with many patients experiencing multiple complications. Early complications occurred in nine (24.3%) patients. Late complications also occurred in 24.3% of patients. There were four (10.8%) patients with five admissions for bowel obstruction, two of whom required operative intervention (5.4%). CONCLUSIONS: Use of STC-I as an initial procedure in the treatment of refractory IBD-related colitis in children is a safe and reasonable surgical approach that allows weaning from immunosuppressing mediations and stops colonic bleeding. Implementing a laparoscopic approach to subtotal colectomy provides further benefit by reducing postoperative length of stay.

Inconsistency in Opioid Prescribing Practices After Pediatric Ambulatory Hernia Surgery.

INTRODUCTION: Nonmedical opioid use is a major public health problem. There is little standardization in opioid-prescribing practices for pediatric ambulatory surgery, which can result in patients being prescribed large quantities of opioids. We have evaluated the variability in postoperative pain medication given to pediatric patients following routine ambulatory pediatric surgical procedures. METHODS: Following IRB approval, pediatric patients undergoing umbilical hernia repair, inguinal hernia repair, hydrocelectomy, and orchiopexy from 2/1/2017 to 2/1/2018 at our tertiary care children's hospital were retrospectively reviewed. Data collected include operation, surgeon, resident or fellow involvement, utilization of preoperative analgesia, opioid prescription on discharge, and patient follow-up. RESULTS: Of 329 patients identified, opioids were prescribed on discharge to 37.4% of patients (66.3% of umbilical hernia repairs, 20.6% of laparoscopic inguinal hernia repairs, and 33.3% of open inguinal hernia repairs [including hydrocelectomies and orchiopexies]). For each procedure, there was large intrasurgeon and intersurgeon variability in the number of opioid doses prescribed. Opioid prescription ranged from 0 to 33 doses for umbilical hernia repairs, 0 to 24 doses for laparoscopic inguinal repairs, and 0 to 20 doses prescribed for open inguinal repairs, hydrocelectomies, and orchiopexies. Pediatric surgical fellows were less likely to discharge a patient with an opioid prescription than surgical resident prescribers (P < 0.01). In addition, surgical residents were more likely to prescribe more than twelve doses of opioids than pediatric surgical fellows (P < 0.01). Increasing patient age was associated with an increased likelihood of opioid prescription (P < 0.01). There were two phone calls and two clinic visits for pain control issues with equal numbers for those with and without opioid prescriptions. CONCLUSIONS: There is significant variation in opioid-prescribing practices after pediatric surgical procedures; increased awareness may help minimize this variability and reduce overprescribing. Training level has an impact on the frequency and quantity of opioids prescribed.

Outpatient curettage and electrocautery as an alternative to primary surgical closure for pediatric gastrocutaneous fistulae.

BACKGROUND: The development of a gastrocutaneous fistula (GCF) after gastrostomy tube removal is a frequent complication that occurs 5%-45% of the time. Conservative therapy with chemical cauterization is frequently unsuccessful, and surgical GCF repair with open primary layered closure of the gastrotomy is often required. We describe an alternative approach of GCF closure that is an outpatient, less invasive procedure that allows patients to avoid the comorbidities of general endotracheal anesthesia and intraabdominal surgery. METHODS: This is an Institutional Review Board approved retrospective review of all patients who underwent GCF closure from January 2010 to July 2016 at a tertiary care children's hospital. Demographics including age, weight, body mass index, comorbidities, and initial indication for gastrostomy tube were recorded. Operative details such as ASA score, operative duration, type of anesthesia, and airway were noted. Based on surgeon preference, two types of operative closure were used during that time frame: primary layered closure or curettage and cautery (C&C). The latter is a procedure in which the fistula tract is first scraped with a fine curette, and then the fistula opening and tract are cauterized circumferentially. Finally, the presence of a persistent fistula and the need for formal reoperation were determined. RESULTS: Sixty-five unique patients requiring GCF closure were identified. Of those, 44 patients (67.6%) underwent primary closure and 21 patients (32.3%) underwent C&C. The success rate of primary closure was 97% with one patient experiencing wound breakdown with persistent fistula. The overall success rate of C&C was 66.7% (14/21). Among those 14 patients, 11 (52.4%) GCF patients were closed by 1 mo. An additional two patients' gastrocutaneous fistulae were closed by 4 mo (61.9%). One GCF was successfully closed with a second C&C procedure. Seven of the 21 patients (33.3%) required subsequent formal layered surgical closure. C&C had significantly shorter operative times (13.5 ± 14.7 min versus 93.4 ± 61.8, P <0.0001) and significantly shorter times in the postanesthesia care unit (101.8 ± 42.4 min versus 147 ± 86, P <0.0001). Patients were intubated with an endotracheal tube 88.6% of the time for primary closure and 23.8% of the time for C&C.Among patients admitted for an elective procedure, the average length of stay for primary closure was 1.9 d as compared to 0 d for the C&C group. Among patients who underwent C&C with a persistent fistula, there were no significant differences in time since initial creation of gastrostomy, age, body mass index, or ASA score. CONCLUSIONS: Our study verifies that primary closure remains the gold standard for persistent GCF. However, C&C is a safe, outpatient procedure that effectively treats a GCF the majority of the time in children. We suggest that in select patients, it may be an appropriate initial and definitive procedure for GCF closure.

Management of pilonidal disease.

PURPOSE OF REVIEW: Pilonidal disease, and the treatment associated with it, can cause significant morbidity and substantial burden to patients' quality of life. Despite the plethora of surgical techniques that have been developed to treat pilonidal disease, discrepancies in technique, recurrence rates, complications, time to return to work/school and patients' aesthetic satisfaction between treatment options have led to controversy over the best approach to this common acquired disease of young adults. RECENT FINDINGS: The management of pilonidal disease must strike a balance between recurrence and surgical morbidity. The commonly performed wide excision without closure has prolonged recovery, while flap closures speed recovery time and improve aesthetics at the expense of increased wound complications. Less invasive surgical techniques have recently evolved and are straightforward, with minimal morbidity and satisfactory results. SUMMARY: As with any surgical intervention, the ideal treatment for pilonidal disease would be simple and cost-effective, cause minimal pain, have a limited hospital stay, low recurrence rate and require minimal time off from school or work. Less invasive procedures for pilonidal disease may be favourable as an initial approach for these patients reserving complex surgical treatment for refractory disease.

Simple diverticulectomy is adequate for management of bleeding Meckel diverticulum.

PURPOSE: It is unclear whether simple diverticulectomy, rather than segmental bowel resection (SBR), is adequate treatment for gastrointestinal bleeding (GIB) secondary to Meckel diverticulum (MD). There is concern that ulcers in the adjacent bowel may continue to bleed if only the diverticulum is removed. This study seeks to determine if diverticulectomy is satisfactory treatment for bleeding MD. METHODS: A multi-institution, retrospective review was performed for patients with a diagnosis of MD and GIB who underwent simple diverticulectomy or small bowel resection. Exclusion criteria were comorbid surgical conditions and other causes of GIB. The primary outcome was post-operative bleeding during the initial hospitalization. Secondary outcomes were bleeding after discharge, transfusion or additional procedure requirement, re-admission, and overall complications. RESULTS: There were 59 patients who met study criteria (42 diverticulectomy, 17 SBR). One patient in the SBR group had early post-operative bleeding (p = 0.288). There was one re-admission (p = 0.288) and three total complications in the SBR group (p = 0.021). There were no cases of bleeding or other complications in the diverticulectomy group. CONCLUSION: This study suggests that simple diverticulectomy is adequate for treatment of GIB caused by MD. Furthermore, diverticulectomy appears to have a lower overall complication rate.

NCCN Guideline Concordance Improves Survival in Pediatric and Young Adult Rectal Cancer.

BACKGROUND: Although management guidelines in adult rectal cancer are widely studied, no consensus guidelines exist for the management of pediatric and young adult rectal cancer. METHODS: The National Cancer Database (2004-2018) was queried for pediatric (age 0-21) and young adult (age 22-40) patients with rectal cancer. Patients were analyzed for receipt of National Comprehensive Cancer Network (NCCN) guideline-concordant therapy. Impact on survival was evaluated using Cox regression and Kaplan-Meier analysis. RESULTS: 6655 patients (108 pediatric and 6547 young adult patients) with rectal cancer were included. Similar to previously published NCCN quality measures with overall guideline concordance approaching 90 % in adults, 89.6 % of pediatric and 84.6 % of young adult patients were classified as receiving pre-operative guideline-concordant therapy. However, pediatric patients were significantly less likely to receive post-operative guideline-concordant therapy than young adult patients (65.3 % verse 76.7 %, respectively, p = 0.008). Risk of death was significantly lower for pediatric patients who received post-operative guideline-concordant therapy (HR, 0.313; CI, 0.168-0.581; p < 0.001). In young adult patients, risk of death was significantly lower for those who received pre-operative guideline-concordant therapy (HR, 0.376, CI 0.338-0.417, p < 0.001), and post-operative guideline-concordant therapy (HR, 0.456; CI 0.413-0.505; p < 0.001). DISCUSSION: NCCN-based guidelines may reasonably guide peri-operative management decisions and improve survival in pediatric and young adult rectal cancer. Given the rarity of this cancer in young patients, employment of an experienced surgical and oncologic multidisciplinary team, along with discussion and involvement of the patient and family, are keys for balancing risks and benefits to offering the best therapeutic strategy.

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.

When and Where Should Surgery Be Positioned in Pediatric Inflammatory Bowel Disease?

Surgery for children and adolescents with IBD is often thought of as a combination of a failure of medical management and the only option for the severe complications of the disease such as uncontrolled GI bleeding, perforation, fistulae, sepsis, and bowel obstruction. However, in CD, surgery can sometimes be an appropriate option to control disease progression, improve symptoms, allow children to get back on the growth curve, and avoid the toxicities of prolonged use of steroids. In UC, the decision to operate is theoretically curative but the long-term options mandate either intestinal continuity with an ileal pouch or a lifelong ileostomy, both of which can have significant impacts in patients' quality of life.

Management of pediatric appendicitis during the COVID-19 pandemic: A nationwide multicenter cohort study.

BACKGROUND: The COVID-19 pandemic has impacted timely access to care for children, including patients with appendicitis. This study aimed to evaluate the effect of the COVID-19 pandemic on management of appendicitis and patient outcomes. METHODS: A multicenter retrospective study was performed including 19 children's hospitals from April 2019-October 2020 of children (age≤18 years) diagnosed with appendicitis. Groups were defined by each hospital's city/state stay-at-home orders (SAHO), designating patients as Pre-COVID (Pre-SAHO) or COVID (Post-SAHO). Demographic, treatment, and outcome data were obtained, and univariate and multivariable analysis was performed. RESULTS: Of 6,014 patients, 2,413 (40.1%) presented during the COVID-19 pandemic. More patients were managed non-operatively during the COVID-19 pandemic compared to before the pandemic (147 (6.1%) vs 144 (4.0%), p < 0.001). Despite this change, there was no difference in the proportion of complicated appendicitis between groups (1,247 (34.6%) vs 849 (35.2%), p = 0.12). COVID era non-operative patients received fewer additional procedures, including interventional radiology (IR) drain placements, compared to pre-COVID non-operative patients (29 (19.7%) vs 69 (47.9%), p < 0.001). On adjusted analysis, factors associated with increased odds of receiving non-operative management included: increasing duration of symptoms (OR=1.01, 95% CI: 1.01-1.012), African American race (OR=2.4, 95% CI: 1.3-4.6), and testing positive for COVID-19 (OR=10.8, 95% CI: 5.4-21.6). CONCLUSION: Non-operative management of appendicitis increased during the COVID-19 pandemic. Additionally, fewer COVID era cases required IR procedures. These changes in the management of pediatric appendicitis during the COVID pandemic demonstrates the potential for future utilization of non-operative management.

Outcomes and Resource Utilization Associated with Use of Routine Pre-Discharge White Blood Cell Count for Clinical Decision-Making in Children with Complicated Appendicitis: A Multicenter Hospital-Level Analysis.

BACKGROUND: The objective was to explore the hospital-level relationship between routine pre-discharge WBC utilization (RPD-WBC) and outcomes in children with complicated appendicitis. METHODS: Multicenter analysis of NSQIP-Pediatric data from 14 consortium hospitals augmented with RPD-WBC data. WBC were considered routine if obtained within one day of discharge in children who did not develop an organ space infection (OSI) or fever during the index admission. Hospital-level observed-to-expected ratios (O/E) for 30-day outcomes (antibiotic days, imaging utilization, healthcare days, and OSI) were calculated after adjusting for appendicitis severity and patient characteristics. Spearman correlation was used to explore the relationship between hospital-level RPD-WBC utilization and O/E's for each outcome. RESULTS: 1528 children were included. Significant variation was found across hospitals in RPD-WBC use (range: 0.7-100%; p < 0.01) and all outcomes (mean antibiotic days: 9.9 [O/E range: 0.56-1.44, p < 0.01]; imaging: 21.9% [O/E range: 0.40-2.75, p < 0.01]; mean healthcare visit days: 5.7 [O/E 0.74-1.27, p < 0.01]); OSI: 14.1% [O/E range: 0.43-3.64, p < 0.01]). No correlation was found between RPD-WBC use and antibiotic days (r = +0.14, p = 0.64), imaging (r = -0.07, p = 0.82), healthcare days (r = +0.35, p = 0.23) or OSI (r = -0.13, p = 0.65). CONCLUSIONS: Increased RPD-WBC utilization in pediatric complicated appendicitis did not correlate with improved outcomes or resource utilization at the hospital level. LEVEL OF EVIDENCE: III.

Postoperative Respiratory Complications in SARS-CoV-2 Positive Pediatric Patients Across 20 United States Hospitals: A Cohort Study.

INTRODUCTION: Data examining rates of postoperative complications among SARS-CoV-2 positive children are limited. The purpose of this study was to evaluate the impact of symptomatic and asymptomatic SARS-CoV-2 positive status on postoperative respiratory outcomes for children. METHODS: This retrospective cohort study included SARS-CoV-2 positive pediatric patients across 20 hospitals who underwent general anesthesia from March to October 2020. The primary outcome was frequency of postoperative respiratory complications, including: high-flow nasal cannula/non invasive ventilation, reintubation, pneumonia, Extracorporeal Membrane Oxygenation (ECMO), and 30-day respiratory-related readmissions or emergency department (ED) visits. Univariate analyses were used to evaluate associations between patient and procedure characteristics and stratified analyses by symptoms were performed examining incidence of complications. RESULTS: Of 266 SARS-CoV-2 positive patients, 163 (61.7%) were male, and the median age was 10 years (interquartile range 4-14). The majority of procedures were emergent or urgent (n = 214, 80.5%). The most common procedures were appendectomies (n = 78, 29.3%) and fracture repairs (n = 40,15.0%). 13 patients (4.9%) had preoperative symptoms including cough or dyspnea. 26 patients (9.8%) had postoperative respiratory complications, including 15 requiring high-flow oxygen, 8 with pneumonia, 4 requiring non invasive ventilation, 3 respiratory ED visits, and 2 respiratory readmissions. Respiratory complications were more common among symptomatic patients than asymptomatic patients (30.8% vs. 8.7%, p = 0.01). Higher ASA class and comorbidities were also associated with postoperative respiratory complications. CONCLUSIONS: Postoperative respiratory complications are less common in asymptomatic versus symptomatic SARS-COV-2 positive children. Relaxation of COVID-19-related restrictions for time-sensitive, non urgent procedures in selected asymptomatic patients may be reasonably considered. Additionally, further research is needed to evaluate the costs and benefits of routine testing for asymptomatic patients. LEVEL OF EVIDENCE: Iii, Respiratory complications.

Provider education leads to sustained reduction in pediatric opioid prescribing after surgery.

BACKGROUND: The majority of opioid overdose admissions in pediatric patients are associated with prescription opioids. Post-operative prescriptions are an addressable source of opioids in the household. This study aims to assess for sustained reduction in opioid prescribing after implementation of provider-based education at nine centers. METHODS: Opioid prescribing information was collected for pediatric patients undergoing umbilical hernia repair at nine centers between December 2018 and January 2019, one year after the start of an education intervention. This was compared to prescribing patterns in the immediate pre- and post-intervention periods at each of the nine centers. RESULTS: In the current study period, 29/127 (22.8%) patients received opioid prescriptions (median 8 doses) following surgery. There were no medication refills, emergency department returns or readmissions related to the procedure. There was sustained reduction in opioid prescribing compared to pre-intervention (22.8% vs 75.8% of patients, p<0.001, Fig. (1). Five centers showed statistically significant improvement and the other four demonstrated decreased prescribing, though not statistically significant. CONCLUSIONS: Our multicenter study demonstrates sustained reduction in opioid prescribing after pediatric umbilical hernia repair after a provider-based educational intervention. Similar low-fidelity provider education interventions may be beneficial to improve opioid stewardship for a wider variety of pediatric surgical procedures.

Association of Gangrenous, Suppurative, and Exudative Findings With Outcomes and Resource Utilization in Children With Nonperforated Appendicitis.

Importance: The clinical significance of gangrenous, suppurative, or exudative (GSE) findings is poorly characterized in children with nonperforated appendicitis. Objective: To evaluate whether GSE findings in children with nonperforated appendicitis are associated with increased risk of surgical site infections and resource utilization. Design, Setting, and Participants: This multicenter cohort study used data from the Appendectomy Targeted Database of the American College of Surgeons Pediatric National Surgical Quality Improvement Program, which were augmented with operative report data obtained by supplemental medical record review. Data were obtained from 15 hospitals participating in the Eastern Pediatric Surgery Network (EPSN) research consortium. The study cohort comprised children (aged ≤18 years) with nonperforated appendicitis who underwent appendectomy from July 1, 2015, to June 30, 2020. Exposures: The presence of GSE findings was established through standardized, keyword-based audits of operative reports by EPSN surgeons. Interrater agreement for the presence or absence of GSE findings was evaluated in a random sample of 900 operative reports. Main Outcomes and Measures: The primary outcome was 30-day postoperative surgical site infections (incisional and organ space infections). Secondary outcomes included rates of hospital revisits, postoperative abdominal imaging, and postoperative length of stay. Multivariable mixed-effects regression was used to adjust measures of association for patient characteristics and clustering within hospitals. Results: Among 6133 children with nonperforated appendicitis, 867 (14.1%) had GSE findings identified from operative report review (hospital range, 4.2%-30.2%; P < .001). Reviewers agreed on presence or absence of GSE findings in 93.3% of cases (weighted κ, 0.89; 95% CI, 0.86-0.92). In multivariable analysis, GSE findings were associated with increased odds of any surgical site infection (4.3% vs 2.2%; odds ratio [OR], 1.91; 95% CI, 1.35-2.71; P < .001), organ space infection (2.8% vs 1.1%; OR, 2.18; 95% CI, 1.30-3.67; P = .003), postoperative imaging (5.8% vs 3.7%; OR, 1.70; 95% CI, 1.23-2.36; P = .002), and prolonged mean postoperative length of stay (1.6 vs 0.9 days; rate ratio, 1.43; 95% CI, 1.32-1.54; P < .001). Conclusions and Relevance: In children with nonperforated appendicitis, findings of gangrene, suppuration, or exudate are associated with increased surgical site infections and resource utilization. Further investigation is needed to establish the role and duration of postoperative antibiotics and inpatient management to optimize outcomes in this cohort of children.

Limiting hospital resources for acute appendicitis in children: Lessons learned from the U.S. epicenter of the COVID-19 pandemic.

INTRODUCTION: The COVID-19 pandemic resulted in the suspension of nonemergent surgeries throughout New York. Our tertiary care children's hospital pivoted towards a brief trial of intravenous (IV) antibiotic therapy in all patients in order to limit operating room (OR) utilization and avoid prolonged hospital stays. We describe our pandemic-based strategy for non-operative management (NOM) of appendicitis but with a limited duration of IV antibiotics. METHODS: We performed a retrospective study of children treated for acute appendicitis at our center from 3/31/2020 to 5/3/2020 during the peak of the New York pandemic. We compared appendicitis volume to similar months in prior years. We evaluated failure of NOM, length of stay, and compared characteristics of children we successfully treated with our expanded NOM protocol to previously published inclusion criteria for NOM. RESULTS: 45.5% of children (25/55) with acute appendicitis underwent NOM. Of the 30 who underwent surgery, 13 had complicated appendicitis while 17 had simple appendicitis. Three patients were COVID-positive, although none had respiratory symptoms. The majority of patients presenting with acute appendicitis (78.2%) did not meet previously published criteria for NOM. CONCLUSIONS: We treated a similar volume of children with acute appendicitis during the pandemic compared to prior years. We applied non-operative management to nearly half our patients, even as we expanded inclusion criteria for NOM to reduce OR utilization, but limited the duration of the antibiotic trial to avoid prolonged hospital stays. TYPE OF STUDY: Retrospective study. LEVEL OF EVIDENCE: IV.

Early Experience with Variant Two-Stage Approach in Surgical Management of Inflammatory Bowel Disease Colitis in the Pediatric Population.

Introduction: Multistaged surgical management of inflammatory bowel disease (IBD), culminating in ileal pouch-anal anastomosis (IPAA), can provide cure for refractory IBD symptoms while maintaining fecal continence. Surgical approaches to IPAA historically included a three-stage approach done by subtotal colectomy (STC) followed by IPAA with diversion. Recently, a variant two-stage approach without diversion at IPAA has become increasingly utilized, yet evidence of the efficacy of this approach is limited. Methods: Retrospective review of patients aged 5-21 years who underwent initial STC, followed by a total proctocolectomy with IPAA +/- diversion for medically refractory IBD from January 2010 to August 2018 (n = 25). Results: Majority of IPAA procedures were done laparoscopically (88.5%). Thirteen patients (52%) underwent two-stage variant IPAA. There were no differences in readmission rates (66.7% versus 53.8%, P = .5) or reoperation rates (50% versus 30.8%, P = .3) between groups. Forty percent of patients experienced a complication after IPAA. Complication rates were similar between two-stage and three-stage IPAA groups (38.5% versus 50%, P = .33). Complications within the two-stage group included anastomotic leak, pouchitis, wound infection, anastomotic stricture, and incarcerated hernia. Complications within the three-stage group included bloody ostomy output, dehydration, anastomotic stricture, small bowel obstruction, and pouch volvulus. Conclusions: Treatment of refractory IBD in children remains challenging, but STC followed by IPAA is an approach that provides symptom relief and preserves continence. Complication rates remained unchanged regardless of whether IPAA was conducted with or without diversion, demonstrating that the two-stage variant approach is a safe and feasible treatment that may reduce subsequent anesthesia exposure and trips to the operating room.
