Abstract
BACKGROUND The goal of this study was to investigate factors associated with 30-day readmission in a multivariate model, including the CDC wound classes "clean," "clean/contaminated," "contaminated," and "dirty/infected." METHODS The 2017-2020 American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for all patients undergoing total hip replacement, coronary artery bypass grafting, Ivor Lewis esophagectomy, pancreaticoduodenectomy, distal pancreatectomy, pneumonectomy, and colectomies. ACS-defined wound classes were concordant with CDC definitions. Multivariate linear mixed regression was used to determine risk factors for readmission while adjusting for type of surgery as a random intercept. RESULTS 477,964 cases were identified, with 38,734 (8.1%) patients having experienced readmission within 30 days of surgery. There were 181,243 (37.9%) cases classified as wound class "clean", 215,729 (45.1%) cases classified as "clean/contaminated", 40,684 cases (8.5%) classified as "contaminated", and 40,308 (8.4%) cases classified as "dirty/infected". In the multivariate generalized mixed linear model adjusting for type of surgery, sex, body mass index, race, American Society of Anesthesiologists class, presence of comorbidity, length of stay, urgency of surgery, and discharge destination, "clean/contaminated" (p < .001), "contaminated" (p < .001), and "dirty/infected" (p < .001) wound classes (when compared to "clean") were significantly associated with 30-day readmission. Organ/space surgical site infection and sepsis were among the most common reasons for readmission in all wound classes. CONCLUSIONS Wound classification was strongly prognostic for readmission in multivariable models, suggesting that it may serve as a marker of readmissions. Surgical procedures that are "non-clean" are at significantly greater risk for 30-day readmission. Readmissions may be due to infectious complications; optimizing antibiotic use or source control to prevent readmission are areas of future study.

Abstract
BACKGROUND Wound assessment is a critical part of the care of hospitalized infants in neonatal intensive care. Early recognition and initiation of appropriate treatment of wounds are imperative to facilitate wound healing and avoid complications such as secondary infection and wound dehiscence. There are, however, no validated tools for assessing surgical wounds in infants. PURPOSE The aim of this study was to develop and interrogate a tool for the assessment of surgical wounds. Specific aims for the tool included interrater reliability (give a consistent and dependable result independent of user) and test criterion validity (give an accurate assessment of the wound compared with an expert). METHODS This was an exploratory cohort study involving a structured wound tool applied by nursing staff to 40 surgical wounds. The wounds were also assessed by wound experts (a pediatric wound care nurse and a pediatric surgeon). Comparisons were made to elucidate estimates of reliability and validity. RESULTS The wound tool demonstrated interrater reliability with intraclass correlation coefficient of 0.775 (95% CI, 0.665-0.862) as well as criterion validity with rank correlation coefficient of 0.55 (95% CI, 0.34-0.76) to 0.71 (95% CI, 0.53-0.88). To obtain 100% sensitivity to distinguish mild from moderate-severe wounds, a low cutoff score was needed. IMPLICATIONS FOR PRACTICE AND RESEARCH Wound assessment continues to be a subjective exercise, even with the utilization of a tool. Additional research is needed for strategies to support the assessment of surgical wounds in infants. Such tools are needed for future research, particularly when multiple institutions are involved.

Abstract
Background: To establish the role of surgical antibiotic prophylaxis (SAP) in the prevention of surgical site infection (SSI) in children undergoing surgery. Design: A systematic review and meta-analysis of six databases: MEDLINE (PubMed), EMBASE, CINAHL Plus, Cochrane Library, Web of Science, and Scopus. Study Selection: Included studies (irrespective of design) compared outcomes in children undergoing surgery, aged 0 to 21 years who received SAP with those who did not, with SSI as an outcome, using the U.S. Centers for Disease Control and Prevention (CDC) definitions for SSI. Data Extraction: Two independent reviewers applied eligibility criteria, assessed the risk of bias, and extracted data. Results: A total of six randomized control trials and 26 observational studies including 202,593 surgical procedures among 202,405 participants were included in the review. The pooled odds ratio of SSI was 1.20; (95% confidence interval [CI], 0.91-1.58) comparing those receiving SAP with those not receiving SAP, with moderate heterogeneity in effect size between studies (τ2 = 0.246; χ2 = 69.75; p < 0.001; I2 = 57.0%). There was insufficient data on many factors known to be associated with SSI, such as cost, length of stay, re-admission, and re-operation; it was therefore not possible to perform subanalyses on these. Conclusions: This review and metanalysis did not find a preventive action of SAP against SSI, and our results suggest that SAP should not be used in surgical wound class (SWC) I procedures in children. However, considering the poor quality of included studies, the principal message of this study is in highlighting the absence of quality data to drive evidence-based decision-making in SSI prevention in children, and in advocating for more research in this field.

Abstract
Surgical site infection (SSI) rates in low- and middle-income countries (LMICs) range from 8 to 30% of procedures, making them the most frequent healthcare-acquired infection (HAI) with substantial morbidity, mortality, and economic impacts. Presented here is an approach to surgical site infection prevention based on surveillance and focused on five critical areas identified by international experts. These five areas include 1. Collecting valid, high-quality data; 2. Linking HAIs to economic incapacity, underscoring the need to prioritize infection prevention activities; 3. Implementing SSI surveillance within infection prevention and control (IPC) programs to enact structural changes, develop procedural skills, and alter healthcare worker behaviors; 4. Prioritizing IPC training for healthcare workers in LMICs to conduct broad-based surveillance and to develop and implement locally applicable IPC programs; and 5. Developing a highly accurate and objective international system for defining SSIs, which can be translated globally in a straightforward manner. Finally, we present a clear, unambiguous framework for successful SSI guideline implementation that supports developing sustainable IPC programs in LMICs. This entails 1. Identifying index operations for targeted surveillance; 2. Identifying IPC “champions” and empowering healthcare workers; 3. Using multimodal improvement measures; 4. Positioning hand hygiene programs as the basis for IPC initiatives; 5. Use of telecommunication devices for surveillance and healthcare outcome follow-ups. Additionally, special considerations for pediatric SSIs, antimicrobial resistance development, and antibiotic stewardship programs are addressed.

Abstract
BACKGROUND Inaccurate assignment of surgical wound class (SWC) remains a challenge in perioperative documentation. The purpose of our intervention was to increase the accuracy of SWC through a targeted training program directed toward pediatric surgeons and nurses. METHODS A retrospective electronic medical record (EMR) chart review of 400 operations was performed according to NSQIP criteria during specified periods in 2014 and 2017, assessing SWC errors before and after a training program and posting of reference materials in operating rooms at a 165-bed children's hospital. After each operation, nurses confirmed SWC with the surgeon before recording the value in the EMR. Differences in proportions of misclassified SWC were evaluated with a chi-square test. RESULTS Following the educational program, misclassified SWC improved from 70/200 (35.0%) to 18/200 (9.0%), p < 0.001. Misclassified SWC for appendectomies improved from 46/95 (48.4%) to 12/108 (11.1%), p < 0.001. CONCLUSIONS Accurate SWC assignment in the EMR was improved by an educational program and posting of materials to aid assignment, as well as enhanced communication between surgeons and nurses at the conclusion of each operation. We present the first known attempt to list all pediatric surgery procedures according to SWC. Accurate SWC allows stratification of risks and more effective targeted interventions.

Abstract
BACKGROUND Misclassification of wounds in the operating room (OR) can adversely affect surgical site infection (SSI) reporting and reimbursement. This study aimed to measure the effects of a curriculum on documentation of surgical wound classification (SWC) for operating room staff and surgeons. METHODS Accuracy of SWC was determined by comparing SWC documented by OR staff during the original operation to SWC determined by in-depth chart review. Patients 18 years or older undergoing inpatient surgical procedures were included. Two plan-do-act-study (PDSA) cycles were implemented over the course of 9 months. A total of 747 charts were reviewed. Accuracy of SWC documentation was retrospectively assessed across 248 randomly selected surgeries during a 5-week period prior to interventions and compared to 244 cases and 255 cases of post-intervention data from PDSA1 and PDSA2, respectively. Changes in SWC accuracy were assessed pre- and post-intervention using the kappa coefficient. A p-value for change in agreement was computed by comparing pre- and post-intervention kappa. RESULTS Inaccurate documentation of surgical wound class decreased significantly following curriculum implementation (kappa improved from 0.553 to 0.739 and 0.757; p = 0.001). Classification accuracy improved across all wound classes; however, class III and IV wounds were more frequently misclassified than class I and II wounds, both before and after the intervention. CONCLUSION Implementation of a multidisciplinary documentation curriculum resulted in a significant decrease in SWC documentation error. Improved accuracy of SWC reporting may facilitate a better assessment of SSI risk in a complex patient population.

Abstract
BACKGROUND Surgical wound classification, introduced in 1964, stratifies the risk of surgical site infection (SSI) based on a clinical estimate of the inoculum of bacteria encountered during the procedure. Recent literature has questioned the accuracy of predicting SSI risk based on wound classification. We hypothesized that a more specific model founded on specific patient and perioperative factors would more accurately predict the risk of SSI. STUDY DESIGN Using all observations from the 2012 to 2014 pediatric National Surgical Quality Improvement Program-Pediatric (NSQIP-P) Participant Use File, patients were randomized into model creation and model validation datasets. Potential perioperative predictive factors were assessed with univariate analysis for each of 4 outcomes: wound dehiscence, superficial wound infection, deep wound infection, and organ space infection. A multiple logistic regression model with a step-wise backwards elimination was performed. A receiver operating characteristic curve with c-statistic was generated to assess the model discrimination for each outcome. RESULTS A total of 183,233 patients were included. All perioperative NSQIP factors were evaluated for clinical pertinence. Of the original 43 perioperative predictive factors selected, 6 to 9 predictors for each outcome were significantly associated with postoperative SSI. The predictive accuracy level of our model compared favorably with the traditional wound classification in each outcome of interest. CONCLUSIONS The proposed model from NSQIP-P demonstrated a significantly improved predictive ability for postoperative SSIs than the current wound classification system. This model will allow providers to more effectively counsel families and patients of these risks, and more accurately reflect true risks for individual surgical patients to hospitals and payers.

Abstract
BACKGROUND Wound classification has catapulted to the forefront of surgical literature and quality care discussions. However, it has not been validated in laparoscopy or children. We analyzed pediatric infection rates based on wound classification and reviewed the most common noninfectious complications which could be a more appropriate measure for quality assessment. METHODS We performed a retrospective review of 800 patients from 2011 to 2014 undergoing common procedures at a tertiary pediatric hospital. Demographics, procedure, wound classification and complications were analyzed using descriptive statistics. RESULTS Infection rates were in the expected low range for clean procedures. However, 5% of pyloromyotomy patients required readmission and 10% of circumcision patients developed penile adhesions; 2% required reoperation. Ostomy reversal, a clean contaminated case, had 17% wound infections, whereas acute appendicitis, a contaminated case had only a 4% infection rate. Laparoscopic cholecystectomy (clean-contaminated or contaminated depending on inflammation) had 2% postoperative infections. Perforated appendicitis, a dirty procedure had an 18% infection rate, below the expected >27% for dirty cases in adults. CONCLUSIONS Current wound classifications do not accurately approximate the risk of surgical site infections in children, particularly for laparoscopic procedures. It would be more appropriate to grade hospitals based on disease and procedure specific complications.
