Pediatric intraoperative cardiopulmonary arrests: A survey to evaluate if Medical Emergency Teams are utilized in pediatric operating rooms.

BACKGROUND: Studies have shown that standardized code teams may improve outcomes following cardiac arrests. Pediatric intra-operative cardiac arrests are rare events and are associated with a mortality rate of 18%. There is limited data available regarding use Medical Emergency Team (MET) response to pediatric intra-operative cardiac arrest. The purpose of this study was to identify the use of MET in response to pediatric intraoperative cardiac arrest as an exploratory step in establishing evidence-based standardized practice across the hospital for training and management of this rare event. METHODS: An anonymous electronic survey was created and sent to two populations: The Pediatric Anesthesia Leadership Council, a section of the Society for Pediatric Anesthesia, and the Pediatric Resuscitation Quality Collaborative, a multinational collaborative group, which works to improve resuscitation care in children. Standard summary and descriptive statistics were used for survey responses. RESULTS: The overall response rate was 41%. The majority of respondents worked in a university affiliated, free-standing children's hospital. Ninety-five percent of respondents had a dedicated pediatric MET at their hospital. In 60% of responses from Pediatric Resuscitation Quality Collaborative and 18% of Pediatric Anesthesia Leadership Council hospitals, the MET responds to pediatric intra-operative cardiac arrest; however, the majority of times MET involvement is requested rather than automatic. The MET was found to be activated intraoperatively for situations other than cardiac arrest such as, massive transfusion events, need for extra staff, and for specialty expertise. In 65% of institutions, simulation-based training for cardiac arrest is supported but lacking pediatric intra-operative focus. CONCLUSIONS: This survey revealed heterogeneity in the composition and response of the medical response teams responding to pediatric intra-operative cardiac arrests. Improved collaboration and cross training among MET, anesthesia, and operating room nursing may improve outcomes of pediatric intra-operative code events.

Examining Implicit Bias Differences in Pediatric Surgical Fellowship Letters of Recommendation Using Natural Language Processing.

OBJECTIVE: We analyzed the prevalence and type of bias in letters of recommendation (LOR) for pediatric surgical fellowship applications from 2016-2021 using natural language processing (NLP) at a quaternary care academic hospital. DESIGN: Demographics were extracted from submitted applications. The Valence Aware Dictionary for sEntiment Reasoning (VADER) model was used to calculate polarity scores. The National Research Council dataset was used for emotion and intensity analysis.  The Kruskal-Wallis H-test was used to determine statistical significance.  SETTING: This study took place at a single, academic, free standing quaternary care children's hospital with an ACGME accredited pediatric surgery fellowship. PARTICIPANTS: Applicants to a single pediatric surgery fellowship were selected for this study from 2016 to 2021. A total of 182 individual applicants were included and 701 letters of recommendation were analyzed. RESULTS: Black applicants had the highest mean polarity (most positive), while Hispanic applicants had the lowest.  Overall differences between polarity distributions were not statistically significant.   The intensity of emotions showed that differences in "anger" were statistically significant (p=0.03).  Mean polarity was higher for applicants that successfully matched in pediatric surgery. DISCUSSION: This study identified differences in LORs based on racial and gender demographics submitted as part of pediatric surgical fellowship applications to a single training program. The presence of bias in letters of recommendation can lead to inequities in demographics to a given program. While difficult to detect for humans, natural language processing is able to detect bias as well as differences in polarity and emotional intensity. While the types of emotions identified in this study are highly similar among race and gender groups, the intensity of these emotions revealed differences, with "anger" being most significant. CONCLUSION: From this work, it can be concluded that bias in LORs, as reflected as differences in polarity, which is likely a result of the intensity of the emotions being used and not the types of emotions being expressed.   Natural language processing shows promise in identification of subtle areas of bias that may influence an individual's likelihood of successful matching.

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.

Risk factors for prolonged hospitalization and readmission after total thyroidectomy in children: Associations with surgical subspecialty.

BACKGROUND: Total thyroidectomy (TT) in children is performed by pediatric general surgeons (P-GS), pediatric otolaryngologists (P-ENT), or adult GS/ENT. This study evaluated short-term pediatric TT outcomes, focusing on surgical subspecialties. METHODS: Pediatric (<18 years) TT with/without central limited lymph node dissection (CLND) between 2015 and 2020 were obtained from the National Surgical Quality Improvement Program-Pediatric database. Risk factors for prolonged hospitalization (PH,>2 days) and 30-day readmission were investigated with multivariate logistic regression. RESULTS: Of 1535 patients, 14% had PH and 2% were readmitted. PH rates for P-ENT vs. P-GS vs. adult were 21% vs. 11% vs. 10%, respectively. Adjusted risk of PH was higher for P-ENT (OR 1.70, p = 0.003) but similar for P-GS/adult. There was no difference for risk of readmission by subspecialty. CONCLUSION: PH is more likely after pediatric TT performed by P-ENT, as compared to P-GS or adult surgeons. While TT may be performed safely by individual subspecialties, collaboration across specialties may further optimize outcomes.

Financial and Safety Impact of Simulation-based Clinical Systems Testing on Pediatric Trauma Center Transitions.

Simulation offers multiple tools that apply to medical settings, but little is known about the application of simulation to pediatric trauma workflow changes. Our institution recently underwent significant clinical changes in becoming an independent pediatric trauma center. We used a simulation-based clinical systems testing (SbCST) approach to manage change-associated risks. The purpose of this study was to describe our SbCST process, evaluate its impact on patient safety, and estimate financial costs and benefits. Methods: SbCST consisted of the following steps: (1) change-based needs assessment, in which stakeholders developed relevant simulation scenarios; (2) scenario implementation; and (3) postsimulation failure mode and effects analysis (FMEA) to identify latent safety threats (LSTs). LSTs were prioritized for mitigation based on the expected probability and severity of adverse event occurrences. We calculated the costs associated with the simulation process. We conservatively estimated SbCST cost savings using 3 approaches: (1) FMEA-based avoidance of adverse events; (2) avoidance of trauma readmissions; and (3) avoidance of medical liability lawsuits. Results: We implemented 2 simulation scenarios prechange. FMEA revealed 49 LSTs, of which 9 were highest priority (catastrophic severity and high likelihood of occurrence). These were prioritized and mitigated using the hospital's quality/safety framework. Cost-benefit analysis based on FMEA event avoidance demonstrated net cost savings to the institution ranging from $52,000-227,000 over the 3-month postchange period. Readmission-based and liability-based estimates also produced favorable results. Conclusions: The SbCST approach identified multiple high-impact safety risks and financially benefited the institution in managing significant pediatric trauma clinical process changes.

Multicenter Comparison of Laparoscopic Versus Open Repair of Duodenal Atresia in Neonates.

Introduction: Traditional duodenal atresia (DA) repair involves a laparotomy. There have been reports of laparoscopic repair (LAP), in lieu of the open laparotomy approach (OPN), with varying degrees of success. The merit of this alternative warrants continued investigation. The purpose of this study was to determine whether there were outcome differences after neonatal DA repair based on surgical approach. Methods: IRB approved retrospective review of the National Surgical Quality Improvement Program Pediatric database (2012-2018) was conducted. International Classification of Diseases (ICD)-9 (751.1) and ICD-10 codes (Q41.0) identified DA repair. Patient demographics, perioperative, and postoperative variables were collected. Univariate and multivariate analysis was performed. Unadjusted and adjusted logistic regression models assessed associations between surgical approach and outcomes. Results: A total of 917 cases were identified, 803 (87.6%) OPN, 75 (8.2%) LAP, and 39 (4.2%) LAP to OPN. Median age at surgery was 2 days (interquartile range [IQR] = 1-3). Females represented 56% of the LAP (n = 42), and 51% of the OPN (n = 412, P = .470). The LAP group had higher weight at surgery (2.8 kg, IQR = 2.3-3.1), compared with the OPN (2.6 kg, IQR = 2.1-2.9, P = .009); and longer operative time (161 minutes, IQR = 107-206; OPN 106 minutes, IQR = 85-135, P < .001). In unadjusted models, median postoperative stay was 4 days shorter (95% confidence interval = -7.5 to -0.5) among LAP compared with OPN. Adjusted models for postoperative stay, complication risks, and unplanned reoperation were not statistically different. Conclusion: Most DA repairs are performed through OPN. LAP resulted in shorter length of stay in unadjusted models. Similar incidence of complications and reoperation suggest that LAP may be as safe as OPN, when employed by skilled experienced pediatric surgeons.
