An Electronic Health Record-integrated Web Application Augments a QI-directed Morbidity & Mortality Conference and Improves Quality of Care.

BACKGROUND: In 2014, we developed a QI-directed Morbidity and Mortality (M&M) Conference, prioritizing discussion of individual and system failures, as well as development of action items to prevent failure recurrence. However, due to a reliance on individual electronic documents to store M&M data, our ability to assess trends in failures and action item implementation was hindered. To address this issue, in 2019, we created a secure electronic health record (EHR)-integrated web application (web app) to store M&M data. STUDY DESIGN: In this study, we assessed the impact of our web app on efficient review and tracking of M&M data, including system failure occurrence and closure of action items. Additionally, in 2021, it was discovered that a backlog of action items existed. To address this issue, we implemented a QI initiative to reduce the backlog, and used the web app to compare action item closure over time. RESULTS: Use of the web app dramatically improved review of M&M data. During the study period, there was a 67.0% reduction in the occurrence of the most common system failures. Additionally, our QI initiative resulted in a 97.7% reduction in the duration of time to complete a single action item and a 61.1% increase in the on-time closure rate for action items. CONCLUSIONS: Integration of a web app into a QI-directed M&M Conference enhanced our ability to track system level failures and action item closure over time. Using this web app, we demonstrated that our M&M Conference achieved its intended goal of improving the quality of patient care. LEVEL OF EVIDENCE: IV.

Giant Omphaloceles-Morbidity, Mortality, and Financial Impact of Early Versus Delayed Repair.

INTRODUCTION: We compared strategy outcomes and financial impact over the first two years of life (F2YOL) for patients with giant omphaloceles undergoing early repair (ER) (primary or staged) versus delayed repair (DR). METHODS: A retrospective review of giant omphaloceles (fascial defect > 5 cm/> 50% liver herniation) at a tertiary children's hospital between 1/1/2010 and 12/31/2019 was performed. Survival, length of stay, age at repair, ventilation days (VD), time to full enteral feeds, readmissions during the F2YOL, incidence of major associated anomalies, and total hospitalization charges during the F2YOL were compared. A subanalysis removing potential confounders and only including patients who underwent fascial closure within the F2YOL was also conducted. RESULTS: Thirty four giant omphaloceles (23DR and 11ER) were identified. The median age (days) at repair was 289 [148, 399] DR versus 10 [5, 21] ER, P < 0.001. Total cohort two-year survival was significantly higher in the DR group (95.7% versus 63.6%, P = 0.03). Including patients with a tracheostomy there was no significant difference in VD during the index hospitalization. Excluding tracheostomy patients, the DR group had significantly fewer VD during the index hospitalization, 15 [0, 15] versus 18 [10, 54], P = 0.02 and over the F2YOL 6.5 [ 0, 21] versus 18 [14, 43], P = 0.03. There were no significant differences in the incidence/type of major associated anomalies, time to full enteral feeds, index length of stay, total hospital days, total admissions, or associated hospital charges. On subanalysis, there was no significant difference in VD or survival at any time. CONCLUSIONS: Delayed and early repair strategies for giant omphaloceles have equivalent outcomes in the index hospitalization and over the course of the first two years of life. These findings are useful for family counseling and expectation setting.

A Review of Covered Abdominal Wall Defects: Cord Hernias Are Associated With Major Anomalies.

INTRODUCTION: Covered abdominal wall defects (CAWD) can be categorized into giant omphaloceles (GOs), nongiant omphaloceles (NGOs), and umbilical cord hernias (UCHs). We sought to evaluate differences in management and outcomes of the different CAWD, treated at a large tertiary children's hospital, with regards to survival and association with other major congenital anomalies. METHODS: A retrospective review of CAWD patients between January 2010 and January 2021 was conducted. GO was defined as a fascial defect >5 cm or >50% liver herniation. UCH were defined as fascial defects ≤ 2 cm. All others were classified as NGO. Type of repair, time to fascial closure, index hospitalization length of stay (LOS), and survival rates were compared. Four major anomaly categories were identified: cardiac, midline, Beckwith-Weidemann Syndrome, and other genetic anomalies. RESULTS: We identified 105 CAWD patients (UCH n = 40; GO n = 34; and NGO n = 31). Ninety percent of UCH underwent primary repair, 10% were never repaired. NGOs were repaired by primary or staged methods in 92.9% of cases and 7.1% by delayed repair. Primary or staged repair occurred in 32.4% of GOs and delayed repair occurred in 67.6%. The median days to repair was 181 [24,427] GO, 1 [1,3] NGO, and 1 [0,1] UCHs (P < 0.01). Index hospitalization median LOS (days) was 90 [55,157] GO, 23 [10,48] NGO, 9 [5,22] UCH, (P < 0.01). There were no statistical differences in survival rates, number of patients with major anomalies (GO 35.4%, NGO 51.5%, UCH 50%), or types of anomalies. CONCLUSIONS: UCHs and omphaloceles have similar incidences of major associated anomalies. Thus, all patients with a covered abdominal wall defect should undergo workup for associated anomalies.

Pediatric blunt cerebrovascular injuries: A national trauma database study.

BACKGROUND: The incidence of blunt cerebrovascular injuries (BCVIs) in children is unknown. We aimed to determine the rate and consequences of BCVIs in pediatric blunt trauma patients. METHODS: We queried the National Trauma Data Bank (NTDB) for all blunt trauma patients between 2007 and 2014. BCVI patients were identified by ICD-9 codes. Demographic, emergency room, and concomitant injury data were analyzed. RESULTS: There were 732,702 blunt trauma patients, and 1682 BCVIs were identified (0.23%). 791 (47%) sustained carotid artery injuries (CAIs), 957 (57%) had vertebral artery injuries (VAIs), and 4% of patients sustained both. A majority of the injuries occurred in white patients (61%) and in motor vehicle accidents (53%). The average age was 12.1 ±â€¯5.4 years. CAIs had more skull base fractures (55% vs 35%, p < 0.0001), and cervical spine fractures were more common in VAIs (26 vs 11%, p < 0.0001). Intensive care length of stay was longer in the CAI patients (9.2 vs 7.9 days, p = 0.03), as was length of stay (12.5 vs 9.7 days, p = 0.0002). 5% of CAI patients were coded for stroke, versus 2% of VAIs (p = 0.002). CONCLUSIONS: BCVIs are rare in children. Vertebral injuries are more common. Carotid injuries are associated with a longer length of stay and higher stroke rates. TYPE OF STUDY: Retrospective cohort study. LEVEL OF EVIDENCE: III.

Orientation in Perpetuity: An Online Clinical Decision Support System for Surgical Residents.

BACKGROUND: Limiting variability is an essential element to improving quality of care. Frequent resident turnover represents a significant barrier to clinical standardization. Trainees joining new surgical services must familiarize themselves with the guidelines and protocols that direct patient care as well as their learning objectives and expectations. A clinical decision support system (CDSS) is a dynamic, searchable electronic resource intended for use at the point of care. The CDSS can provide convenient and timely access to relevant information for residents, allowing them to incorporate the most up-to-date protocols and guidelines in their daily care of patients. The objective of this quality improvement intervention was to determine the objective rate of CDSS utilization and its subjective value to residents. MATERIALS AND METHODS: An internally developed, web-based CDSS including essential, clinically useful documents was created for use by trainees on a busy pediatric surgery service. A standardized orientation was provided to each resident and fellow on joining the service, complemented by a summary card to be attached to the trainee's ID badge. CDSS usage was monitored using web analytics. Trainees who rotated before and after the CDSS launch were surveyed regarding attitudes toward clinical resources and confidence in patient management. RESULTS: Documents published to the CDSS included 33 clinical guideline documents and 207 additional educational and support files including reference materials from service orientation were made available to trainees and staff. Goals for resident usage were established by evaluation and adaptation of early traffic patterns. Analysis of web traffic collected over 14 consecutive months revealed utilization above target levels, with 4.0 average weekly page views per trainee (IQR: 1.6-5.6). A total of 60 survey responses were received (54% of trainees invited); majorities of rotating trainees and survey respondents were trainees in general surgery and most were interns. Mean composite scores reflected a trend toward improved satisfaction when seeking CDSM (before intervention 3.18 [SD 0.73], after intervention 3.92 [SD 0.70], range 1-5) which was statistically significant (P = 0.005). Mean scores also improved across five of six components of the composite score (mean improvement 0.75, range: 0.53-0.92), four of which were statistically significant (P = 0.001-0.038). Most (59%) respondents reported that they used the CDSS frequently. CONCLUSIONS: Convenient access to a CDSS resulted in greater than expected utilization as well as higher resident satisfaction with and confidence in materials provided. A CDSS is a promising tool offering quick access to high-quality information in challenging trainee environments.

Development and Implications of an Evidence-based and Public Health-relevant Definition of Complicated Appendicitis in Children.

OBJECTIVE: To characterize the influence of intraoperative findings on complications and resource utilization as a means to establish an evidence-based and public health-relevant definition for complicated appendicitis. SUMMARY OF BACKGROUND DATA: Consensus is lacking surrounding the definition of complicated appendicitis in children. Establishment of a consensus definition may have implications for standardizing the reporting of clinical research data and for refining reimbursement guidelines. METHODS: This was a retrospective cohort study of patients ages 3 to 18 years who underwent appendectomy from January 1, 2013 to December 31, 2014 across 22 children's hospitals (n = 5002). Intraoperative findings and clinical data from the National Surgical Quality Improvement Program-Pediatric Appendectomy Pilot Database were merged with cost data from the Pediatric Health Information System Database. Multivariable regression was used to examine the influence of 4 intraoperative findings [visible hole (VH), diffuse fibrinopurulent exudate (DFE) extending outside the right lower quadrant (RLQ)/pelvis, abscess, and extra-luminal fecalith] on complication rates and resource utilization after controlling for patient and hospital-level characteristics. RESULTS: At least 1 of the 4 intraoperative findings was reported in 26.6% (1333/5002) of all cases. Following adjustment, each of the 4 findings was independently associated with higher rates of adverse events compared with cases where the findings were absent (VH: OR 5.57 [95% CI 3.48-8.93], DFE: OR 4.65[95% CI 2.91-7.42], abscess: OR 8.96[95% CI 5.33-15.08], P < 0.0001, fecalith: OR 5.01[95% CI 2.02-12.43], P = 0.001), and higher rates of revisits (VH: OR 2.02 [95% CI 1.34-3.04], P = 0.001, DFE: OR 1.59[95% CI 1.07-2.37], P = 0.02, abscess: OR 2.04[95% CI 1.2-3.49], P = 0.01, fecalith: OR 2.31[95% CI 1.06-5.02], P = 0.04). Each of the 4 findings was also independently associated with increased resource utilization, including longer cumulative length of stay (VH: Rate ratio [RR] 3.15[95% CI 2.86-3.46], DFE: RR 3.06 [95% CI 2.83-3.13], abscess: RR 3.94 [95% CI 3.55-4.37], fecalith: RR 2.35 [95% CI 1.87-2.96], P =  < 0.0001) and higher cumulative hospital cost (VH: RR 1.97[95% CI 1.64-2.37], P < 0.0001, DFE: RR 1.8[95% CI 1.55-2.08], P =  < 0.0001, abscess: RR 2.02[95% CI 1.61-2.53], P < 0.0001, fecalith: RR 1.49[95% CI 0.98-2.28], P = 0.06) compared with cases where the findings were absent. CONCLUSION AND RELEVANCE: The presence of a visible hole, diffuse fibrinopurulent exudate, intra-abdominal abscess, and extraluminal fecalith were independently associated with markedly worse outcomes and higher cost in children with appendicitis. The results of this study provide an evidence-based and public health-relevant framework for defining complicated appendicitis in children.

Improving Quality of Chest Computed Tomography for Evaluation of Pediatric Malignancies.

INTRODUCTION: Atelectasis is a problem in sedated pediatric patients undergoing cross-sectional imaging, impairing the ability to accurately interpret chest computed tomography (CT) imaging for the presence of malignancy, often leading to additional maneuvers and/or repeat imaging with additional radiation exposure. METHODS: A quality improvement team established a best-practice protocol to improve the quality of thoracic CT imaging in young patients with suspected primary or metastatic pulmonary malignancy. The specific aim was to increase the percentage of chest CT scans obtained for the evaluation of pulmonary nodules with acceptable atelectasis scores (0-1) in patients aged 0-5 years with malignancy, from a baseline of 45% to a goal of 75%. RESULTS: A retrospective cohort consisted of 94 patients undergoing chest CT between February 2014 and January 2015 before protocol implementation. The prospective cohort included 195 patients imaged between February 2015 and April 2018. The baseline percentage of CT scans that were scored 0 or 1 on the atelectasis scale was 44.7%, which improved to 75% with protocol implementation. The mean atelectasis score improved from 1.79 (±0.14) to 0.7 (±0.09). Sedation incidence decreased substantially from 73.2% to 26.5% during the study period. CONCLUSIONS: Using quality improvement methodology including standardization of care, the percentage of children with atelectasis scores of 0-1 undergoing cross-sectional thoracic imaging improved from 45% to 75%. Also, eliminating the need for sedation in these patients has further improved image quality, potentially allowing for optimal detection of smaller nodules, and minimizing morbidity.

Volume of Irrigation Does Not Affect Rate of Abscess in Perforated Appendicitis.

Background: Although previous studies have evaluated whether use of irrigation decreases postoperative intraabdominal abscess (PO-IAA) formation, these studies treated irrigation as a dichotomous variable and concluded that no irrigation resulted in a decreased incidence of PO-IAA formation. However, a recent study found decreased incidence with small aliquots to a total volume of 6 L. We hypothesized that higher volumes of irrigation would result in a lower incidence of PO-IAA. Materials and Methods: A postoperative template was developed as a quality improvement initiative and included descriptors for complex appendicitis and volume of irrigation. Data were prospectively collected from February 2016 to December 2018. Patients with complex appendicitis (fibropurulent exudate, extraluminal fecalith, well-formed abscess, visible hole in the appendix) were identified and analyzed by using standard statistical analysis. Volume of irrigation was categorized for analysis. Results: Two thousand three hundred six appendicitis patients were identified; 408 had complex appendicitis (17.7%). Three hundred eighty-four patients with complex appendicitis had documented irrigation volumes. The overall incidence of PO-IAA was 13.8%. Irrigation was commonly used (92.7%). The median amount of irrigation was 1000 mL (500 mL, 2500 mL), but it ranged from none to 9000 mL. There was no overall difference in the volume of irrigation used between those who developed a PO-IAA and those who did not (P = .34). No specific intraoperative finding was associated with the development of PO-IAA. Increasing volume of irrigation did not lower PO-IAA incidence (P = .24). Conclusions: The volume of irrigation did not appear to affect the rate of PO-IAA formation. The use of irrigation should be left to the discretion of the operating surgeon.

Safety and feasibility of skin-to-skin care for surgical infants: A quality improvement project.

BACKGROUND: Skin-to-skin care (SSC) for infants improves physiologic stability, pain perception, brain development, parental bonding, and overall survival. Using quality improvement (QI) methodology, this project aimed to increase SSC for surgical infants in the neonatal intensive care unit (NICU). METHODS: A multidisciplinary working group composed of key NICU stakeholders instituted a needs assessment querying perceptions and concerns about SSC. Based on survey results, multiple system level interventions were implemented. Data for surgical infants receiving SSC during hospitalization were tracked over time using the electronic health record. RESULTS: Overall, 315 infants requiring a surgical consult were admitted to the NICU in the first 12 months of the project. After six months, SSC rates in this group increased from 51% to 60.5% (p < 0.01) and were sustained for 12 months. After one year, nursing staff reporting that they were somewhat to very comfortable providing SSC for surgical infants increased from 44% to 75% (p = 0.001) and the percent of nurses providing SSC for a surgical infant increased from 12% to 37% (p = 0.001). Inadvertent extubation did not significantly increase after implementation of the QI project. CONCLUSIONS: Using QI methodology and multidisciplinary engagement, SSC was integrated safely into the routine care of surgical infants in the NICU. LEVEL OF EVIDENCE: Level V.

Gangrenous appendicitis: No longer complicated.

BACKGROUND: Appendicitis presents on a spectrum ranging from inflammation to gangrene to perforation. Studies suggest that gangrenous appendicitis has lower postoperative infection rates relative to perforated cases. We hypothesized that gangrenous appendicitis could be successfully treated as simple appendicitis, reducing length of stay (LOS) and antibiotic usage without increasing postoperative infections. METHODS: In February 2016, we strictly defined complex appendicitis as a hole in the appendix, extraluminal fecalith, diffuse pus or a well-formed abscess. We switched gangrenous appendicitis to a simple pathway and reviewed all patients undergoing laparoscopic appendectomy for 12 months before (Group 1) and 12 months after (Group 2) the protocol change. Data collected included demographics, appendicitis classification, LOS, presence of a postoperative infection, and 30-day readmissions. RESULTS: Patients in Group 1 and Group 2 were similar, but more cases of simple appendicitis occurred in Group 2. Average LOS for gangrenous appendicitis patients decreased from 2.5 to 1.4 days (p < 0.001) and antibiotic doses decreased from 5.2 to 1.3 (p < 0.001). Only one gangrenous appendicitis patient required readmission, and one patient in each group developed a superficial infection; there were no postoperative abscesses. CONCLUSIONS: Gangrenous appendicitis can be safely treated as simple appendicitis without increasing postoperative infections or readmissions. TYPE OF STUDY: Prognosis study. LEVEL OF EVIDENCE: Level II.

Computed tomography rates and estimated radiation-associated cancer risk among injured children treated at different trauma center types.

BACKGROUND: Trauma is a common indication for computed tomography (CT) in children. However, children are particularly vulnerable to CT radiation and its associated cancer risk. Identifying differences in CT usage across trauma centers and among specific populations of injured children is needed to identify where quality improvement initiatives could be implemented in order to reduce excess radiation exposure to children. We evaluated computed tomography (CT) rates among injured children treated at pediatric (PTC), mixed (MTC), or adult trauma centers (ATC) and estimated the resulting differential in potential cancer risk. METHODS: We identified children age ≤18 years with blunt injury AIS ≥2 treated from 2010 to 2013 at 130 U.S trauma centers participating in the Trauma Quality Improvement Program. CT rates were compared across center types using Chi-square analysis. Stratified analyses in children with varying injury severity, mechanism, and age were performed. We estimated the impact of differential rates of CT scans on cancer risk using published attributable risks. RESULTS: Among 59,010 children identified, CT rates were higher among injured children treated at ATC and MTC versus PTC. Findings were consistent after stratified analyses and were most striking in children with chest and abdomen/pelvis CT, adolescent age, low injury severity and fall injury mechanism. We estimated that for every 100,000 injured children, imaging practices in ATC and MTC would lead to an additional 17 and 16 lifetime cancers, respectively, when compared to PTC. CONCLUSION: CT use among injured children is higher at ATC and MTC compared to PTC. Children with low injury severity, fall injury mechanism, and adolescent age are most vulnerable to differential imaging practices across centers. Quality improvement initiatives aimed at reducing heterogeneity in CT usage across trauma centers are required to mitigate pediatric radiation exposure and cancer risk.

Association of Intraoperative Findings With Outcomes and Resource Use in Children With Complicated Appendicitis.

Importance: The influence of disease severity on outcomes and use of health care resources in children with complicated appendicitis is poorly characterized. Adjustment for variation in disease severity may have implications for ensuring fair reimbursement and comparative performance reporting among hospitals. Objective: To examine the association of intraoperative findings as a measure of disease severity with complication rates and resource use in children with complicated appendicitis. Design: This retrospective cohort study used clinical data from the American College of Surgeons National Surgical Quality Improvement Program pediatric appendectomy pilot database (NSQIP-P database) and cost data from the Pediatric Health Information System database. Twenty-two children's hospitals participated in the NSQIP Pediatric Appendectomy Collaborative Pilot Project. Patients aged 3 to 18 years with complicated appendicitis who underwent an appendectomy from January 1, 2013, through December 31, 2014, were included in the study. Appendicitis was categorized in the NSQIP-P database as complicated if any of the following 4 intraoperative findings occurred in the operative report: visible hole, fibropurulent exudate in more than 2 quadrants, abscess, or extraluminal fecalith. Data were analyzed from January 1, 2013, through December 31, 2014. Main Outcomes and Measures: Thirty-day postoperative adverse event rate, revisit rate, hospital cost, and length of stay. Multivariable regression was used to estimate event rates and outcomes for all observed combinations of intraoperative findings, with adjusting for patient characteristics and clustering within hospitals. Results: A total of 1333 patients (58.7% boys; median age, 10 years; interquartile range, 7-12 years) were included; multiple intraoperative findings of complicated appendicitis were reported in 589 (44.2%). Compared with single findings, the presence of multiple findings was associated with higher rates of surgical site infection (odds ratio, 1.40; 95% CI, 0.95-2.06; P = .09), higher revisit rates (odds ratio, 1.60; 95% CI, 1.15-2.21; P = .005), longer length of stay (rate ratio, 1.45; 95% CI, 1.36-1.55; P < .001), and higher hospital cost (rate ratio, 1.35; 95% CI, 1.19-1.53; P < .001). Significant differences were found among different combinations of intraoperative findings for all outcomes, including a 3.6-fold difference in rates of surgical site infection (range, 7.5% for fecalith alone to 27.2% for all 4 findings; P = .002), a 2.6-fold difference in revisit rates (range, 8.9% for exudate alone to 22.9% for all 4 findings; P = .001), a 2.2-fold difference in length of stay (range, 4.0 days for exudate alone to 8.9 days for all 4 findings; P < .001), and a 2.4-fold difference in mean cumulative cost (range, $13 296 for exudate alone to $32 282 for all 4 findings; P < .001). Conclusions and Relevance: More severe presentations of complicated appendicitis are associated with worse outcomes and greater resource use. Severity adjustment may be needed to ensure fair reimbursement and comparative performance reporting, particularly at hospitals treating underserved populations where more severe presentations are common.

Ambulatory pediatric surgery.

Ambulatory pediatric surgery has become increasingly common in recent years, with greater numbers of procedures being performed on an outpatient basis. This practice has clear benefits for hospitals and healthcare providers, but patients and families also often prefer outpatient surgery for a variety of reasons. However, maximizing the potential opportunities requires critical attention to patient and procedure selection, as well as anesthetic choice. A subset of outpatient procedures can be performed as single visit procedures, further simplifying the process for families and providers.

Hospital variation in rates of concurrent fundoplication during gastrostomy enteral access procedures.

BACKGROUND: This study aimed to determine whether (1) the propensity for concurrent fundoplication during gastrostomy varies among hospitals, and (2) postoperative morbidity differs among institutions performing fundoplication more or less frequently. METHODS: Children who underwent gastrostomy with or without concurrent fundoplication were identified in the American College of Surgeons National Surgical Quality Improvement Program Pediatric (ACS-NSQIP-P). A hierarchical multivariate regression modeled the excess effects that hospitals exerted over propensity for concurrent fundoplication adjusting for preoperative clinical variables. Hospitals were designated as low outliers (significantly lower-adjusted odds of concurrent fundoplication than the average hospital with similar patient mix), average hospitals, and high outliers based on their risk-adjusted concurrent fundoplication practice. The postoperative morbidity rates were compared among low-outlier, average, and high-outlier hospitals. RESULTS: Between 2011 and 2013, 3775 children underwent gastrostomy at one of 54 ACS-NSQIP-P participating hospitals. The mean hospital concurrent fundoplication rate was 11.7% (range 0-64%). There was no significant difference in unadjusted morbidity rate in children with concurrent fundoplication, 11.0% compared to 9.7% in children without concurrent fundoplication. After controlling for clinical variables, 8 hospitals were identified as low outliers (fundoplication rate of 0.4%) and 16 hospitals were identified as high outliers (fundoplication rate of 34.6%). The average unadjusted morbidity rate among hospitals with low, average, and high odds of concurrent fundoplication were 9.6, 10.6, and 8.4%, respectively. CONCLUSION: Hospitals vary significantly in propensity for concurrent fundoplication during gastrostomy yet postoperative morbidity does not differ significantly among institutions performing fundoplication more or less frequently.

Effective methods to decrease surgical site infections in pediatric gastrointestinal surgery.

BACKGROUND: Gastrointestinal (GI) surgeries represent a significant proportion of the surgical site infection (SSI) burden in pediatric patients, resulting in significant morbidity. Previous studies have shown that perioperative bundles reduce SSIs, but few have focused on pediatric GI operations. We hypothesized that a GI bundle would decrease SSI rates, length of stay (LOS), and hospital charges. METHODS: After establishing baseline SSI rates, a GI bundle was created and implemented in November 2014. We prospectively collected data including demographics, procedure type, LOS, inpatient charges, bundle compliance, and SSI development. We analyzed SSI rates, LOS, and charges using process control charts. RESULTS: The baseline SSI rate for all GI operations was 3.4%, which increased to 7.1%, then decreased to 4.7%. Midgut/hindgut and stoma closure SSI rates decreased from 11.3% to 8.0% (p<0.05) and 21.4% to 7.9%, respectively (p<0.05). Although overall LOS and charges were unchanged, average LOS for midgut/hindgut surgeries and stoma closures decreased from 20.3 to 13.6days (p=0.015) and 12.6 to 7.9days (p=0.04), respectively. Stoma closure charges decreased from $94,262 to $50,088 (p=0.01). CONCLUSIONS: Our perioperative GI bundle decreased SSI rates, primarily among midgut/hindgut operations. Bundle usage decreased LOS and charges most effectively in stoma closures. TYPE OF STUDY: Prognosis Study. LEVEL OF EVIDENCE: Level 2.

Identifying Adverse Events in Pediatric Surgery: Comparing Morbidity and Mortality Conference with the NSQIP-Pediatric System.

BACKGROUND: Recent improvements to morbidity and mortality (M&M) conference have focused on the case review system. However, case selection occurs by physician reporting, which is limited by selection bias. We compared the effectiveness of our M&M conference with the NSQIP-Pediatric (NSQIP-P) system for identifying adverse events. STUDY DESIGN: Complications from January 2010 to September 2015 were compared between M&M and NSQIP-P. Only M&M patients meeting NSQIP-P criteria were compared with patients from the NSQIP-P system; exclusions were studied separately. Complication rates in M&M conference before and after a 2012 format change designed to increase case reporting were also compared. RESULTS: Detection of mortality in M&M conference and NSQIP-P was not different. Morbidity events identified by NSQIP-P were significantly higher than M&M conference during the entire study period (194 vs 100 occurrences/1,000 cases) (p < 0.0001). Morbidity occurrences in M&M conference increased with the 2012 improvements, however, they still remained less than that identified by NSQIP-P (226 vs 141 occurrences/1,000 cases) (p < 0.0001). Of 863 patients presented in M&M conference, 210 were excluded from direct comparison because they did not meet NSQIP-P criteria. These included 62 deaths and 287 occurrences of morbidity. Their analysis in M&M conference resulted in 32 action initiatives directed at system failures. CONCLUSIONS: The NSQIP-P identified more complications than M&M. The M&M conference improvements increased reported cases, but they still remained lower than NSQIP-P. However, M&M conference identified events resulting in systems changes that would not have been identified by NSQIP-P. Although NSQIP-P captures occurrences to compare large patient cohorts, M&M analyzes singular failures and initiates direct interventions. Integration of these systems can optimize their usefulness in quality improvement.

Resource use in pediatric blunt and penetrating trauma.

BACKGROUND: Trauma is one of the leading causes of pediatric morbidity and mortality with significant patient and economic impacts that necessitate constant study. Significant differences in outcomes and resource use exist between blunt and penetrating mechanisms. METHODS: The National Trauma Data Bank was analyzed for patients aged 0-18 y with International Classification of Diseases, 9th Revision injury codes for blunt and penetrating trauma from 2007-2012. Demographic information, causes, treatments, complications, and outcomes were assessed. RESULTS: A total of 748,347 pediatric trauma patients were assessed. Blunt trauma was identified as the cause in 601,898 (80.43%) patients compared with 55,597 (7.4%) patients with penetrating trauma. Blunt trauma patients were younger on average and more likely to be female. Despite having a slightly higher mean injury severity scores, blunt trauma patients had shorter length of stay in the hospital (2.9 versus 4.3 d, P < 0.001), fewer complications (34.8% versus 38.6%, P < 0.001), and a much lower mortality rate (1.3% versus 7.1%, P < 0.001). Blunt trauma patients were more likely to undergo computed tomography scanning but less likely to receive transfusions (1.79% versus 5.5%, P < 0.001) and to undergo exploratory laparotomy (0.9% versus 9.4%, P < 0.001) and thoracotomy (0.07% versus 1.7%, P < 0.001). Variations in outcome and resource use were also noted by age. CONCLUSIONS: Compared with penetrating trauma, blunt trauma is more common and patients have shorter length of stay, less complications, lower mortality, and are less likely to need operative intervention or blood transfusion. Resource use also varied by age.

Variation in intraoperative and postoperative red blood cell transfusion in pediatric surgery.

BACKGROUND: Intraoperative and postoperative red blood cell (RBC) transfusions are relatively frequent events tracked in the American College of Surgeons' National Surgical Quality Improvement Program-Pediatric (ACS-NSQIP-P). This study sought to quantify variation in RBC transfusion practices among hospitals. STUDY DESIGN AND METHODS: This is an observational study of children older than 28 days who underwent a general, neurologic, urologic, otolaryngologic, plastic, or orthopedic operation at 50 hospitals in participating in the ACS-NSQIP-P during 2011 to 2012. The primary outcome was whether or not a RBC transfusion was administered from incision time to 72 hours postoperatively. Transfusions of fresh-frozen plasma, cryoprecipitate, and platelets were excluded from data abstraction due the rarity of their administration. A multivariate hierarchical risk-adjustment model estimated the risk-adjusted hospital RBC transfusion odds ratio (OR) and designated hospitals by transfusion practice. RESULTS: The mean RBC transfusion rate was 1.5%. Five preoperative variables were associated with greater than threefold increased odds of having an intraoperative or postoperative RBC transfusion; young age; 29 days to 1 year (OR, 5.9; p < 0.001) and 1 to 2 years (OR, 3.4; p < 0.001); American Society of Anesthesiologists Class IV (OR, 3.2; p < 0.001); procedure linear risk (OR, 3.1; p < 0.001); preoperative septic shock (OR, 14.5; p < 0.001); and preoperative cardiopulmonary resuscitation (OR, 8.1; p < 0.001). Twenty-five hospitals had RBC transfusion practices significantly different than risk-adjusted mean (17 higher and eight lower). CONCLUSION: Intraoperative and postoperative RBC transfusion practices vary widely among hospitals after controlling for patient and procedural characteristics.

Postoperative timing of computed tomography scans for abscess in pediatric appendicitis.

BACKGROUND: One-quarter to one half of pediatric appendicitis patients present with ruptured appendicitis and about 3%-25% go on to form postoperative intra-abdominal abscesses. The optimal timing of postoperative imaging for suspected abscess formation has been a subject of debate. METHODS: All patients who underwent appendectomy for complex appendicitis and were not discharged before postoperative day (POD) #5 from April 2012-October 2014 were identified. Patients were stratified into groups for comparison as follows: group 1 had postoperative computed tomography (CT) scans before POD#7 (n = 26) and group 2 did not (n = 169). Group 2 was further divided into those who were afebrile (group 2a, n = 106) or febrile (group 2b, n = 63) at POD#5. RESULTS: A total of 195 patients met criteria. Early use of CT scans resulted in more drainage procedures (group 1, 73.1% versus group 2b, 28.6%, P < 0.001) and a higher recurrent CT scan rate (38.5% versus 9.5%). The groups had equivalent lengths of stay (11.9 versus 9.8 d, P = 0.10) and readmission rates due to abscesses (19.2% group 1 versus 6.3%, group 2b, P = 0.12) with no septic events. In total, 130 of the 169 patients (76.9%) in group 2 had resolution of symptoms before discharge without intervention with readmission for abscess in only 5.9%. CONCLUSIONS: Waiting until POD#7 before scanning led to fewer drainage procedures and recurrent CT scans without increasing length of stay or readmission rates. Most complex appendicitis patients still admitted at POD#5 had resolution of symptoms without need for intervention.

Estimating Adverse Events After Gastrostomy Tube Placement.

OBJECTIVE: Gastrostomy feeding tube placement in children is associated with a high frequency of adverse events. This study sought to preoperatively estimate postoperative adverse events in children undergoing gastrostomy feeding tube placement. METHODS: This was an observational study of children who underwent gastrostomy with or without fundoplication at 1 of 50 participating hospitals, using 2011-2013 data from the American College of Surgeons' National Surgical Quality Improvement Program Pediatric. The outcome was the occurrence of any postoperative complications or mortality at 30 days after gastrostomy tube placement. The preoperative clinical characteristics significantly associated with occurrence of adverse events were included in a multivariate logistic model. The area under the receiver operating characteristic curve was computed to assess model performance and split-set validated. RESULTS: A total of 2817 children were identified as having undergone gastrostomy tube placement. The unadjusted rate of adverse events within 30 days after gastrostomy tube placement was 11%. Thirteen predictor variables were identified. Notable preoperative variables associated with a greater than 75% increase in adverse event rate were preoperative sepsis/septic shock (odds ratio [OR], 10.76, 95% confidence interval [CI], 3.84-30.17), central nervous system tumor (OR, 3.36; 95% CI, 1.42-7.95), the primary procedure as indicated by the current procedural terminology (CPT) linear risk variable (OR, 1.93; 95% CI, 1.50-2.49), severe cardiac risk factors (OR, 1.88; 95% CI, 1.17-3.03), and preoperative seizure history (OR, 1.90; 95% CI, 1.38-2.62). The area under the receiver operating characteristic curve was 0.71 with the derivation data set and 0.71 upon split-set validation. CONCLUSIONS: Preoperatively estimating postoperative adverse events in children undergoing gastrostomy tube placement is feasible.
