Collaborative Approach Toward Transplant Candidacy for Obese Patients with End-Stage Renal Disease.

BACKGROUND: An elevated BMI is a major cause of transplant preclusion for patients with end-stage renal disease (ESRD). This phenomenon exacerbates existing socioeconomic and racial disparities and increases the economic burden of maintaining patients on dialysis. Metabolic bariatric surgery (MBS) in such patients is not widely available. Our center created a collaborative program to undergo weight loss surgery before obtaining a kidney transplant. STUDY DESIGN: We studied the outcomes of these patients after MBS and transplant surgery. One hundred eighty-three patients with ESRD were referred to the bariatric team by the transplant team between January 2019 and June 2023. Of these, 36 patients underwent MBS (20 underwent Roux-en-Y gastric bypass and 16 underwent sleeve gastrectomy), and 10 underwent subsequent transplantation, with another 15 currently waitlisted. Both surgical teams shared resources, including dieticians, social workers, and a common database, for easy transition between teams. RESULTS: The mean starting BMI for all referrals was 46.4 kg/m 2 and was 33.9 kg/m 2 at the time of transplant. The average number of hypertension medications decreased from 2 (range 2 to 4) presurgery to 1 (range 1 to 3) postsurgery. Similarly, hemoglobin A1C levels improved, with preoperative averages at 6.2 (range 5.4 to 7.6) and postoperative levels at 5.2 (range 4.6 to 5.8) All transplants are currently functioning, with a median creatinine of 1.5 (1.2 to 1.6) mg/dL (glomerular filtration rate 46 [36.3 to 71]). CONCLUSIONS: A collaborative approach between bariatric and transplant surgery teams offers a pathway toward transplant for obese ESRD patients and potentially alleviates existing healthcare disparities. ESRD patients who undergo MBS have unique complications to be aware of. The improvement in comorbidities may lead to superior posttransplant outcomes.

Nutritional Considerations for Patients With Renal Failure Undergoing Sleeve Gastrectomy.

Obesity is highly prevalent in patients with renal disease, as it contributes to or accelerates the progression of kidney disease and is frequently a barrier to kidney transplantation. Patients with renal disease have unique dietary needs due to various metabolic disturbances resulting from altered processing and clearance of nutrients. They also frequently present with physical disability, resulting in difficulty achieving adequate weight loss through lifestyle modifications. Therefore, kidney transplant candidates may benefit from bariatric surgery, particularly sleeve gastrectomy (SG), as the safest, most effective, and long-lasting weight loss option to improve comorbidities and access to transplantation. However, concerns regarding nutritional risks prevent broader dissemination of SG in this population. No specific guidelines tailored to the nutritional needs of patients with renal disease undergoing SG have been developed. Moreover, appropriate monitoring strategies and interventions for muscle loss and functional status preservation, a major concern in this at-risk population, are unknown. We aimed to summarize the available literature on the nutritional requirements of patients with renal disease seeking SG as a bridge to transplantation. We also provide insight and guidance into the nutritional management pre and post-SG.

GERD-screening before bariatric surgery: the predictive value of the GERD-HRQL questionnaire score compared with preoperative EGD findings.

BACKGROUND: There is an ongoing debate on how to best identify patients with gastroesophageal reflux disease (GERD) before bariatric surgery. The value of routine preoperative esophagogastroduodenoscopy (EGD) is questioned, and patient reported symptoms are commonly used for screening. The goal of this study is to determine if patient reported symptoms using a validated questionnaire correlate with preoperative EGD findings. METHODOLOGY: A prospective cohort study at a single institution was performed. Patients undergoing bariatric surgery between December 2020 and March 2023 were required to report symptoms of reflux by completing a preoperative GERD. Health-Related Quality of Life (GERD-HRQL) questionnaire and undergo a mandatory preoperative screening EGD. Patients were stratified into two cohorts: (group A) asymptomatic (score = 0) and (group B) symptomatic (score > 0). Statistical analysis was conducted using Pearson's chi-squared test and Wilcoxon rank-sum test in RStudio version 4.2.2. The predictive value of the GERD-HRQL score was analyzed using Areas Under the Curve (AUC; AUC = 0.5 not predictive, 0.5 < AUC ≥ 6 poor prediction & AUC > 0.9 excellent prediction) calculated from Receiver Operating Characteristic (ROC) curves. RESULTS: 200 patients were included; median age was 42.0 years (IQR 36.0 to 49.2). There were 79 patients (39.5%) in Group A and 121 patients (60.5%) in Group B. There was no difference in the frequency esophagitis (27.8% vs 32.2%, p = 0.61) or hiatal hernias (49.4% vs 47.1%, p = 0. 867) between group A and group B, respectively. ROC analysis revealed that the total GERD HRQL scores, heartburn only scores and regurgitation only scores, were poor predictors of esophagitis found on EGD (AUC 0.52, 0.53, 0.52), respectively. In asymptomatic patients, higher BMI was significantly associated with esophagitis (OR 1.15, 95% CI 1.06-1.27, p = 0.002). CONCLUSION: Symptoms, identified through the GERD-HRQL questionnaire, are a poor indicator of esophagitis or its severity in patients undergoing workup for bariatric surgery. Therefore, liberal screening upper endoscopy is recommended for pre-bariatric surgery patients to guide appropriate procedure selection.

Battle of the buttress: 5-year propensity-matched analysis of staple-line reinforcement techniques from the MBSAQIP database.

BACKGROUND: Vertical sleeve gastrectomy (VSG) has demonstrated to be safe; however, controversy remains on how to decrease major complications, particularly bleeding and leaks. There are variations in staple-line reinforcement techniques, including no reinforcement, oversewing, and buttressing. We sought to evaluate the effect of those methods on post-operative complications using the Metabolic and Bariatric Surgery Accreditation Quality Initiative Program (MBSAQIP) database. METHODS: The MBSAQIP was queried for patients who underwent VSG during 2015-2019. A propensity-matched analysis was performed between different staple-line reinforcement (SLR) methods, specifically No reinforcement (NR), Oversewing (OS), and Buttressing (BR). The primary outcome of interest was complications within 30 days. RESULTS: A total of 513,354 VSG cases were analyzed. The cohort was majority female (79.0%), with mean (SD) age of 44.2 ± 11.9 years and mean BMI of 45 ± 7.8 kg/m2. Frequency of SLR methods used was 54%BR, 25.6%NR, 10.8% BR + OS, and 9.8%OS. There were no differences in rate of leaks among SLR methods. Compared to NR, BR was associated with decreased rate of reoperations, overall bleeding, and major bleeding (p < 0.05) but prolonged operative time and length of stay (LOS) (p < 0.05). OS was associated with decreased overall bleeding (p < 0.05) but prolonged operative times and length of stay (p < 0.05) compared to NR. Compared to BR, OS was associated with increased operative times, LOS, and rates of post-operative ventilator use, pneumonia, and venous thrombosis (p < 0.05). Patients with bleeding were associated with lower rate of BR (56% vs 61%) and higher rate of NR (34% vs 28%) compared to patients with no bleeding. Bleeding was associated with a greater frequency of leaks (4.4% vs 0.3%), along with higher morbidity and mortality (p < 0.05). CONCLUSIONS: Of the reinforcement methods evaluated, BR and OS were both associated with decreased bleeding despite longer operative times. No method was found to significantly reduce incidence of leaks; however, bleeding was associated with increased incidence of leaks, morbidity, and mortality. The liberal use of SLR techniques is recommended for further optimization of patient outcomes after VSG.

A 5-year propensity-matched analysis of perioperative outcomes in patients with chronic kidney disease undergoing bariatric surgery.

BACKGROUND: Bariatric surgery can improve renal function in patients with comorbid chronic kidney disease (CKD) and obesity. Additionally, bariatric surgery can enhance outcomes following renal transplantation. The safety of bariatric surgery in patients with CKD has been debated in the literature. This study evaluates the frequency of perioperative complications associated with CKD. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried from 2015-2019. Patients were included if they had a vertical sleeve gastrectomy (VSG) or Roux-en-Y gastric bypass (RYGB) and were stratified based on CKD status. An unmatched and propensity-matched analysis was performed comparing 30-day perioperative outcomes between the groups. RESULTS: A total of 717,809 patients included in this study, 5817(0.8%) had CKD, of whom 2266(0.3%) were on dialysis. 74.3% of patients with CKD underwent VSG with 25.7% underwent RYGB. Comparing RYGB to VSG, patients who underwent RYGB had a higher rate of deep organ space infection (0.7%vs.0.1%,p = 0.021) and re-intervention (5.0% vs. 2.2%,p < 0.001). Within the VSG cohort, a matched analysis was performed for those with CKD and without CKD. The CKD cohort had higher risk of complications such as bleeding (2.1%vs. 0.9%,p < 0.001), readmission (9.3%vs.4.9%,p < 0.001), reoperation (2.7%vs.1.3%,p < 0.001), and need for reintervention (2.2%vs.1.3%,p < 0.001). Notably, patients with CKD also had a higher mortality (0.6%vs.0.2%,p = 0.003). No difference was seen between patients with renal insufficiency and patients on dialysis. CONCLUSION: VSG has been the operation of choice in patients with CKD. Our results showed it is the safer option for patients with CKD compared to RYGB. Although this patient population does have an increased risk of adverse perioperative events, dialysis didn't affect the outcome. Bariatric surgeons who operate on patients with CKD should be well informed and remain vigilant given the increased perioperative risk. The risk is still considerably low, and the potential benefit on renal function and improvement in candidacy for renal transplant outweigh the risk. They should be considered as surgical candidates.

Tulane STAR (Sending Texts, Advancing Results): impact of text messaging on bariatric post-operative protocol compliance.

BACKGROUND: Text messaging is frequently employed in the outpatient setting to communicate with or send reminders to patients. However, there is a paucity of literature on the impact of text messaging on inpatient care. In this study, the use of text messaging in hospitalized patients is evaluated by assessing patient compliance to a post-operative bariatric protocol. METHODS: This was a randomized controlled trial that studied compliance to a post-operative bariatric protocol in patients who underwent bariatric surgery at a tertiary, academic medical center between February and May 2021. Patients were randomized to either the control group, in which they received standard post-operative education alone or the Tulane Sending Texts, Advancing Results (STAR) intervention arm, in which participants received the same post-operative education along with two text message reminders to drink water, use their incentive spirometers, and ambulate (per post-operative instructions) on post-operative day (POD) # 0 and POD # 1. The primary outcome was compliance with the protocol, defined as the number of 1-oz cups of water consumed, incentive spirometry usage, and ambulation frequency and distance. Secondary outcomes include length of stay and complications. RESULTS: A total of 35 patients were enrolled in the study (17 control, 18 STAR intervention). There was no significant difference in age, BMI, or type of surgery performed between the two groups. Clear liquid consumption was significantly higher in the STAR intervention group with an average of 27.7 ± 3.5 cups as compared to 18.2 ± 8.9 in the control group (p < 0.001). Similarly, statistically significant increases in incentive spirometry usage (p < 0.01) and ambulation distance and frequency (p < 0.02) were observed in the STAR intervention group. CONCLUSIONS: While patients are in the hospital, text messaging can improve compliance to post-operative protocols. Peri-operative text messaging can enhance patient education and communication.

Should Surgery Residents Receive Pre-operative Skin Preparation Training: An Association of Program Directors in Surgery Survey.

PURPOSE: Surgical site infections (SSI) are a significant source of peri-operative morbidity and a financial burden on the healthcare system. Effective pre-operative skin preparation has been shown to reduce SSI incidence, however studies demonstrated that most healthcare providers do not adhere to proper techniques. Skin prep technique is not taught to U.S. surgical residents in a standardized format. The objective of this study was to perform a survey of U.S. surgical training programs to determine the practice patterns of surgical resident education on the proper techniques of pre-operative antiseptic surgical prep. METHODS: An 18-question anonymous survey was created using the Qualtrics platform. The survey was distributed to members of the Association of Program Directors in Surgery listserv over a 2-month period. Responses were compiled and data analysis was performed. RESULTS: The survey response rate was 30% (n = 85/280). 81% of respondents reported that surgery residents are responsible for performing pre-operative skin prep at their institutions. The same proportion (81%) reported that they feel surgical skin prep techniques are an important component of surgical resident education. However, only 42% reported that their residents are provided formal education regarding proper skin prep techniques and only 6% reported that their residents are required to take a written or practical proficiency exam. 42% of respondents felt that formal skin prep education for residents is likely to affect the rate of surgical site infections. CONCLUSIONS: Surgical residents commonly perform pre-operative skin preparation. However, few residents receive formal education or evaluation of these skills. Given the importance of pre-operative skin preparation in reducing SSIs and the potential for patient harm if performed incorrectly, the results from this study raise the question of whether formal surgical resident education regarding pre-op skin prep should be more widely adopted and standardized.

A Structured Quality Improvement Educational Curriculum Increases Surgical Resident Involvement in QI Processes.

OBJECTIVE: Patient safety and quality improvement (QI) processes are vitally important to healthcare systems. Training and experience in QI processes are mandated by the Accreditation Council for Graduate Medical Education (ACGME) for general surgery residents. The execution and efficacy of these training programs in residencies have thus far been inconsistent. The purpose of this study was to assess the effectiveness of our surgical residency's QI educational program. METHODS: We instituted a formalized QI educational program for all residents in our academic general surgery residency program from 2018 to 2019. The curriculum included didactics, online educational resources, peer-group collaboration, and faculty mentorship. Residents performed a self-assessment survey of their knowledge, skill, and comfort levels with QI processes before and after the program using a 10-point Likert scale. The number of QI projects conducted, presented, and subsequently prepared for publication was enumerated. The ACGME resident survey program results regarding resident involvement in QI processes before and after program implementation were compared. RESULTS: After 1 year of the program, residents demonstrated significant increases in average self-assessed knowledge of QI processes (6.4 vs. 4.0, p < 0.05), knowledge of local QI resources (5.4 vs. 3.3, p < 0.05), and confidence in their ability to develop and implement a QI project (6.3 vs. 3.9, p < 0.05). The average number of QI projects each resident participated in the year preceding the program vs. during the program increased from 0.4 to 1.8 (p < 0.05). Ten of 26 residents (38%) reported no direct involvement in a QI project the preceding year before the QI program implementation, while 26/26 (100%) of residents reported direct involvement in at least 1 QI project during the implementation year. Residency program ACGME survey results regarding resident participation in QI increased from 86% (just below the national average of 87%) before the development of the QI program to 97% after program implementation. CONCLUSION: Implementation of a formalized, structured quality improvement education program for surgery residents significantly increased residents' participation in QI projects, as well as increasing their confidence in their knowledge and skillset to perform QI processes. The residency program's ACGME resident survey results regarding resident involvement in QI also improved during program implementation.

SAGES primer for taking care of yourself during and after the COVID-19 crisis.

COVID-19 is a pandemic which has affected almost every aspect of our life since starting globally in November 2019. Given the rapidity of spread and inadequate time to prepare for record numbers of sick patients, our surgical community faces an unforeseen challenge. SAGES is committed to the protection and care of patients, their surgeons and staff, and all who are served by the medical community at large. This includes physical health, mental health, and well-being of all involved. The fear of the unknown ahead can be paralyzing. International news media have chronicled the unthinkable situations that physicians and other health care providers have been thrust into as a result of the COVID-19 pandemic. These situations include making life or death decisions for patients and their families regarding use of limited health care resources. It includes caring for patients with quickly deteriorating conditions and limited treatments available. Until recently, these situations seemed far from home, and now they are in our own hospitals. As the pandemic broadened its reach, the reality that we as surgeons may be joining the front line is real. It may be happening to you now; it may be on the horizon in the coming weeks. In this context, SAGES put together this document addressing concerns on clinician stressors in these times of uncertainty. We chose to focus on the emotional toll of the situation on the clinician, protecting vulnerable persons, reckoning with social isolation, and promoting wellness during this crisis. At the same time, the last part of this document deals with the "light at the end of the tunnel," discussing potential opportunities, lessons learned, and the positives that can come out of this crisis.

A multicenter, pediatric quality improvement initiative improves surgical wound class assignment, but is it enough?

BACKGROUND/PURPOSE: Surgical wound classification (SWC) is widely utilized for surgical site infection (SSI) risk stratification and hospital comparisons. We previously demonstrated that nearly half of common pediatric operations are incorrectly classified in eleven hospitals. We aimed to improve multicenter, intraoperative SWC assignment through targeted quality improvement (QI) interventions. METHODS: A before-and-after study from 2011-2014 at eleven children's hospitals was conducted. The SWC recorded in the hospital's intraoperative record (hospital-based SWC) was compared to the SWC assigned by a surgeon reviewer utilizing a standardized algorithm. Study centers independently performed QI interventions. Agreement between the hospital-based and surgeon SWC was analyzed with Cohen's weighted kappa and chi square. RESULTS: Surgeons reviewed 2034 cases from 2011 (Period 1) and 1998 cases from 2013 (Period 2). Overall SWC agreement improved from 56% to 76% (p<0.01) and weighted kappa from 0.45 (95% CI 0.42-0.48) to 0.73 (95% CI 0.70-0.75). Median (range) improvement per institution was 23% (7-35%). A dose-response-like pattern was found between the number of interventions implemented and the amount of improvement in SWC agreement at each institution. CONCLUSIONS: Intraoperative SWC assignment significantly improved after resource-intensive, multifaceted interventions. However, inaccurate wound classification still commonly occurred. SWC used in SSI risk-stratification models for hospital comparisons should be carefully evaluated.

Surgical resident education in patient safety: where can we improve?

BACKGROUND: Effective communication and patient safety practices are paramount in health care. Surgical residents play an integral role in the perioperative team, yet their perceptions of patient safety remain unclear. We hypothesized that surgical residents perceive the perioperative environment as more unsafe than their faculty and operating room staff despite completing a required safety curriculum. MATERIALS AND METHODS: Surgeons, anesthesiologists, and perioperative nurses in a large academic children's hospital participated in multifaceted, physician-led workshops aimed at enhancing communication and safety culture over a 3-y period. All general surgery residents from the same academic center completed a hospital-based online safety curriculum only. All groups subsequently completed the psychometrically validated safety attitudes questionnaire to evaluate three domains: safety culture, teamwork, and speaking up. Results reflect the percent of respondents who slightly or strongly agreed. Chi-square analysis was performed. RESULTS: Sixty-three of 84 perioperative personnel (75%) and 48 of 52 surgical residents (92%) completed the safety attitudes questionnaire. A higher percentage of perioperative personnel perceived a safer environment than the surgical residents in all three domains, which was significantly higher for safety culture (68% versus 46%, P = 0.03). When stratified into two groups, junior residents (postgraduate years 1-2) and senior residents (postgraduate years 3-5) had lower scores for all three domains, but the differences were not statistically significant. CONCLUSIONS: Surgical residents' perceptions of perioperative safety remain suboptimal. With an enhanced safety curriculum, perioperative staff demonstrated higher perceptions of safety compared with residents who participated in an online-only curriculum. Optimal surgical education on patient safety remains unknown but should require a dedicated, systematic approach.

Surgical wound classification for pediatric appendicitis remains poorly documented despite targeted interventions.

BACKGROUND/PURPOSE: Surgical wound class (SWC) is used to risk-stratify surgical site infections (SSI) for quality reporting. We previously demonstrated only 8% agreement between hospital-based SWC and diagnosis-based SWC for acute appendicitis. We hypothesized that education and process-based interventions would improve hospital-based SWC reporting and the validity of SSI risk stratification. METHODS: Patients (<18 years old) who underwent appendectomies for acute appendicitis between January 2011 and December 2013 were included. Interventions entailed educational workshops regarding SWC for perioperative personnel and inclusion of SWC as a checkpoint in the surgical safety checklist. Thirty-day postoperative SSIs were recorded. Chi-square, Fisher's exact test, and kappa statistic were utilized. RESULTS: 995 cases were reviewed (pre-intervention=478, post-intervention=517). Weighted interrater agreement between hospital-based and diagnosis-based SWC improved from 50% to 81% (p<0.01), and weighted kappa increased from 0.16 (95% CI 0.004-0.03) to 0.29 (95% CI 0.25-0.34). Hospital-based dirty wounds were significantly associated with SSI in the post-intervention period only (p<0.01). CONCLUSIONS: Agreement between hospital-based SWC and diagnosis-based SWC significantly improved after simple interventions, and SSI risk stratification became consistent with the expected increase in disease severity. Despite these improvements, there were still substantial gaps in SWC knowledge and process.

Surgical wound misclassification: a multicenter evaluation.

BACKGROUND: Surgical wound classification (SWC) is used by hospitals, quality collaboratives, and Centers for Medicare and Medicaid to stratify patients for their risk for surgical site infection. Although these data can be used to compare centers, the validity and reliability of SWC as currently practiced has not been well studied. Our objective was to assess the reliability of SWC in a multicenter fashion. We hypothesized that the concordance rates between SWC in the electronic medical record and SWC determined from the operative note review is low and varies by institution and operation. STUDY DESIGN: Surgical wound classification concordance was assessed at 11 participating institutions between SWC from the electronic medical record and SWC from operative note review for 8 common pediatric surgical operations. Cases with concurrent procedures were excluded. A maximum of 25 consecutive cases were selected per operation from each institution. A designated surgeon reviewed the included operative notes from his/her own institution to determine SWC based on a predetermined algorithm. RESULTS: In all, 2,034 cases were reviewed. Overall SWC concordance was 56%, ranging from 47% to 66% across institutions. Inguinal hernia repair had the highest overall median concordance (92%) and appendectomy had the lowest (12%). Electronic medical records and reviewer SWC differed by up to 3 classes for certain cases. CONCLUSIONS: Surgical site infection risk stratification by SWC, as currently practiced, is an unreliable methodology to compare patients and institutions. Surgical wound classification should not be used for quality benchmarking. If SWC continues to be used, individual institutions should evaluate their process of assigning SWC to ensure its accuracy and reliability.

Impact of a 24-hour discharge pathway on outcomes of pediatric appendectomy.

BACKGROUND: Clinical pathways for simple (nonperforated, nongangrenous) appendicitis potentially could decrease hospital length of stay (LOS) through standardization of patient care. Our institution initiated a simple appendicitis pathway for children with the goal of less than 24-hour discharge (same-day discharge, SDD) and evaluated its effectiveness. METHODS: A prospective cohort of pediatric patients (<18 years of age) who underwent appendectomy for simple appendicitis after implementation of a SDD pathway were compared with a historic cohort of similar patients in this same large children's hospital. Primary outcomes included LOS, surgical-site infections, and readmissions. Mann Whitney U test, Fischer exact test, χ(2) test, and logistic regression were used. RESULTS: Between June 2009 and May 2013, 1,382 appendectomies were performed; 794 (57%) were for simple appendicitis (316 prepathway and 478 pathway). Hospital LOS decreased 37% after pathway implementation from a median (interquartile range) of 35 (20-50) hours to 22 (9-55) hours (P < .001). SDD increased from 13% to 58% (P < .001). Infectious complications were unchanged (1.6% vs 1.8%, P = .82), but readmissions increased (1.2% vs 4.2%, P = .02). CONCLUSION: A standardized pathway for simple appendicitis that targets SDD can be achieved in children; however, a slight increase in readmissions was noted. High risk for readmission, cost effectiveness, and generalizability need to be further determined.

Multifaceted interventions improve adherence to the surgical checklist.

INTRODUCTION: Adherence to surgical safety checklists remains challenging. Our institution demonstrated acceptable rates of checklist utilization but poor adherence to all checkpoints. We hypothesized that stepwise, multifaceted interventions would improve checklist adherence. METHODS: From 2011 to 2013, adherence to the 14-point, pre-incision checklist was assessed directly by trained observers during three, 1-year periods (baseline, observation #1, and observation #2) during which interventions were implemented. Interventions included safety workshops, customization of a stakeholder-derived checklist, and implementation of a report card system. Chi-square and Kruskal-Wallis tests were utilized. RESULTS: Checklist performance was assessed for 873 cases (baseline, n = 144; observation #1, n = 373; observation #2, n = 356). Total checkpoint adherence increased (from 30% to 78% to 96%; P < .001), as did cases with correct completion of all checkpoints (from 0% to 19% to 61%; P < .001). The median (interquartile range) number of checkpoints completed per case improved from 4 (3-5) to 11 (10-12) to 14 (13-14; P < .001). CONCLUSION: A strategic, multifaceted approach to perioperative safety significantly improved checklist adherence over 2 years. Checklist content and process need to reflect local interests and operative flow to achieve high adherence rates. Successful checklist implementation requires efforts to change the safety culture, stakeholder buy-in, and sustained efforts over time.

Component separation for complex congenital abdominal wall defects: not just for adults anymore.

PURPOSE: Operative repair of large abdominal wall defects in infants and children can be challenging. Component separation technique (CST) is utilized in adults to repair large abdominal wall defects but rarely used in children. The purpose of this report is to describe our experience with the CST in pediatric patients including the first description of CST use in newborns. METHODS: After IRB approval, we reviewed all patients who underwent CST between June 1, 2010 and December 31, 2012 at a large children's hospital. CST included dissection of abdominal wall subcutaneous tissue from the muscle and fascia and an incision of the external oblique aponeurosis one centimeter lateral to the rectus sheath. Biologic mesh onlay or underlay was used to reinforce this closure. Patients were followed for complications. RESULTS: Nine children, two patients with gastroschisis and seven with omphalocele, were repaired with CST at median (range) 1.1 years (5 days-10.1 years) of age. CST was the first surgical intervention for five children. There were minor wound complications and no recurrences after a median (range) follow up of 16 months (3-34 months). CONCLUSION: CST can be a very useful technique to repair large abdominal wall defects in children with a loss of abdominal domain.

Quality check of a quality measure: surgical wound classification discrepancies impact risk-stratified surgical site infection rates in pediatric appendicitis.

BACKGROUND: The impact of quality measures in health care and reimbursement is growing. Ensuring the accuracy of quality measures, including any risk-stratification variables, is necessary. Surgical site infection rates, risk stratified by surgical wound classification (SWC) among other variables, are increasingly considered as quality measures. We hypothesized that hospital-documented and diagnosis-based SWCs are frequently discordant and that diagnosis-based SWCs better predict surgical site infection rates. STUDY DESIGN: All pediatric patients (ie, younger than 18 years old) at a single institution who underwent an appendectomy for appendicitis between October 1, 2010 and August 31, 2011 were included. Each chart was reviewed to determine the hospital-documented SWC, which is recorded by the circulating nurse (options included clean, clean-contaminated, contaminated, and dirty); SWC based on the surgeons' postoperative diagnosis, including contaminated (ie, acute nonperforated, nongangrenous appendicitis), dirty (ie, gangrenous and perforated appendicitis), and 30-day postoperative surgical site infections. RESULTS: Of the 312 evaluated appendicitis cases, the diagnosis-based and circulating nurse-based SWCs differed in 288 (92%) cases. The circulating nurse-based and diagnosis-based SWCs differed by more than one SWC in 176 (56%) cases. Surgical site infections were associated with worsening diagnosis-based SWC, but not with circulating nurse-based SWC. CONCLUSIONS: Significant discordance exists between hospital documentation by the circulating nurse- and surgeon diagnosis-based SWCs. Inconsistency in risk-stratified quality measures can have a significant effect on outcomes measures, which can lead to misdirection of quality-improvement efforts, incorrect inter-hospital rating, reduced reimbursements, and public misperceptions about quality of care.

What is the quality of reporting of studies of interventions to increase compliance with antibiotic prophylaxis?

BACKGROUND: Despite studies reporting successful interventions to increase antibiotic prophylaxis compliance, surgical site infections remain a significant problem. The reasons for this lack of improvement are unknown. This review evaluates the internal and external validity of quality improvement studies of interventions to increase surgical antibiotic prophylaxis compliance. STUDY DESIGN: Three investigators independently performed systematic literature searches and selected eligible studies that evaluated interventions to improve perioperative antibiotic prophylaxis timing, type, and/or discontinuation. Studies published before the Surgical Infection Prevention project inception in 2002 were excluded. Each study was assessed based on modified criteria for evaluating quality improvement studies (Standards for Quality Improvement Reporting Excellence) and for facilitating implementation of evidence into practice (Reach-Efficacy-Adoption-Implementation-Maintenance). RESULTS: Forty-six articles met inclusion criteria; 93% reported improvement in antibiotic prophylaxis compliance. Surgical site infections were evaluated in 50% of studies and 65% reported an improvement. Less than 5% of studies used randomization, allocation concealment, or blinding. Nine percent of studies described efforts to minimize bias in the design results and analysis and 13% described a sample size calculation. Approximately one-third of studies described participant adoption of the intervention (26%), factors affecting generalizability (33%), or implementation barriers (37%). Most studies (80%) used multiple interventions; no single intervention was associated with change in compliance. Studies with the lowest baseline compliance showed the greatest improvement, regardless of the intervention(s). CONCLUSIONS: The methodology and reporting of quality improvement studies on perioperative antibiotic prophylaxis is suboptimal, and factors that would improve generalizability of successful intervention implementation are infrequently reported. Clinicians should use caution in applying the results of these studies to their general practice.

Beyond surgical care improvement program compliance: antibiotic prophylaxis implementation gaps.

BACKGROUND: Despite increased compliance with Surgical Care Improvement Project infection measures, surgical-site infections are not decreasing. The aim of this study was to test the hypothesis that documented compliance with antibiotic prophylaxis guidelines on a pediatric surgery service does not reflect implementation fidelity or adherence to guidelines as intended. METHODS: A 7-week observational study of elective pediatric surgical cases was conducted. Adherence was evaluated for appropriate administration, type, timing, weight-based dosing, and redosing of antibiotics. RESULTS: Prophylactic antibiotics were administered appropriately in 141 of 143 cases (99%). Of 100 cases (70%) in which antibiotic prophylaxis was indicated, compliance was documented in 100% cases in the electronic medical record, but only 48% of cases adhered to all 5 guidelines. Lack of adherence was due primarily to dosing or timing errors. CONCLUSIONS: Lack of implementation fidelity in antibiotic prophylaxis guidelines may partly explain the lack of expected reduction in surgical-site infections. Future studies of Surgical Care Improvement Project effectiveness should measure adherence and implementation fidelity rather than just documented compliance.

The impact of chylothorax on neonates with repaired congenital diaphragmatic hernia.

PURPOSE: Chylothorax is a known complication in neonates after congenital diaphragmatic hernia (CDH) repair. This report uses a large international registry to evaluate risk factors, treatment, morbidity, and survival associated with chylothorax in a prospective cohort of neonates after CDH repair. METHODS: From January 2007 to January 2010, live-born neonates with repaired, unilateral CDHs were evaluated from a prospective database for chylothorax development. Chylothorax was diagnosed based on pleural fluid examination. Study variables included patient characteristics, CDH defect and disease severity characteristics, chylothorax treatment, and survival. In addition, the temporal relationship between timing of CDH repair and extracorporeal membrane oxygenation (ECMO) therapy was evaluated as a risk factor for chylothorax. Univariate and multivariate regression analyses were utilized. RESULTS: Among the 1383 patients evaluated, chylothorax was diagnosed in 4.6% of the cohort. Patch repair and ECMO were statistically significant risk factors for chylothorax. The odds of developing a chylothorax were significantly increased in patients with CDH repair on ECMO (aOR 2.6; 95% CI: 1.3-4.9) or after ECMO (aOR 3.1; 95% CI: 1.7-5.8). Most chylothoraces (83.1%) were successfully treated without surgery. Chylothorax patients had significant morbidity including increased oxygen use at 30days and longer length of stay. Survival was not significantly affected by chylothorax. CONCLUSIONS: Chylothorax is a known but uncommon complication of neonatal CDH repair. In this very large series of chylothorax in association with CDH, major risk factors appear to be related to increased disease severity with the highest risk in patients repaired on or after ECMO. Chylothoraces usually improve with conservative therapy and lead to significant morbidity but not increased mortality.
