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
BACKGROUND Wound classification scores are used to categorize the risk of postoperative infections. It was noted at our academic institution that wound classifications were often inaccurately recorded in the electronic health record. We thus instituted a quality improvement program, hypothesizing that this would improve charting accuracy. METHODS On June 1, 2019, we posted the wound classifications in each pediatric operating room (OR), provided OR nurses with teaching, and began including the classification in the postoperative surgeon debriefing. We performed a retrospective chart review of all general pediatric operations from June 19 to December 19 to compare classifications recorded in the electronic health record to the "correct" classification determined by manual review of operating reports. These data were compared with a similar chart review from 2018. To compare the efficacy of nursing versus physician focused changes, we compared our appendectomy data with a nearby community institution where the same group of surgeons practice. Pearson's Chi-squared test was used to report the significance of the differences observed in the concordance proportion, with 95% confidence intervals calculated using the Clopper-Pearson procedure. RESULTS Overall, 444 pre- and 179 postpractice change charts were reviewed. There were no significant differences pre or postpractice change. At the community institution, we noted a significant improvement in charting accuracy for appendectomies from 3.33% to 44.83%. DISCUSSION Despite implementing nursing and physician focused quality improvement practices, there was not a significant improvement in charting accuracy at the academic institution. However, we did note an improvement at the community facility where our pediatric surgeons also practice. We thus suspect that our nursing focused changes may have been inadequate. Future efforts will focus on providing intensive and sustained OR nurse training to help improve the wound classification charting accuracy.

Who gets a PEG? An analysis of simultaneous PEG placement during elective laparoscopic paraesophageal hernia repair. Surg Endosc 2019; 34:686-695. [PMID: 31062155 DOI: 10.1007/s00464-019-06815-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2019] [Accepted: 04/29/2019] [Indexed: 10/26/2022]
Abstract
INTRODUCTION Percutaneous Endoscopic Gastrostomy (PEG) is an infrequent adjunct in elective paraesophageal hernia repair (PEHR). Guidelines denote that PEG "may facilitate postoperative care in selected patients." Though there is sparse literature defining which patients may benefit. The purpose of this study is to determine factors associated with simultaneous PEG placement during PEHR and their subsequent outcomes. METHODS The NSQIP database was queried from 2011 to 2016 for patients undergoing elective laparoscopic PEHR. Cases were excluded if PEHR or fundoplasty was not the primary procedure, a concomitant bariatric procedure was performed, or if the primary surgeon was not a general or cardiothoracic surgeon. Groups were Propensity Score Matched for age, BMI, and ASA Class. RESULTS 15700 patients were identified, 371 who underwent simultaneous PEG placement (2.4%). Non-PEG patients were matched at a 5:1 ratio, producing 1855 controls. PEG patients had higher rates of pre-operative dyspnea (OR 1.45, p = 0.0110), pre-operative weight loss (OR 2.87, p = 0.0001), and lower pre-operative albumin (3.92 vs. 4.01, p = 0.0129). PEG patients had more intra-operative contamination (mean Wound Classification 1.54 vs. 1.38, p < 0.0001) and longer case durations (170 vs. 148 min, p < 0.0001). PEG patients had longer lengths of stay (3.4 vs. 2.5 days, p = 0.0001), rates of superficial SSI (OR 5.82, p = 0.0012), peri-operative transfusions (OR 2.68, p = 0.0197), and pulmonary emboli (OR 3.61, p = 0.0359). CONCLUSION Patients undergoing simultaneous PEG during PEHR are more likely to have respiratory symptoms, markers of malnutrition, and intra-operative factors indicative of more technically challenging cases. These patients have longer hospitalizations, higher rates of superficial SSI, and more pulmonary emboli.

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 Machine-learning can elucidate complex relationships/provide insight to important variables for large datasets. This study aimed to develop an accurate model to predict neonatal surgical site infections (SSI) using different statistical methods. METHODS The 2012-2015 National Surgical Quality Improvement Program-Pediatric for neonates was utilized for development and validations models. The primary outcome was any SSI. Models included different algorithms: full multiple logistic regression (LR), a priori clinical LR, random forest classification (RFC), and a hybrid model (combination of clinical knowledge and significant variables from RF) to maximize predictive power. RESULTS 16,842 patients (median age 18 days, IQR 3-58) were included. 542 SSIs (4%) were identified. Agreement was observed for multiple covariates among significant variables between models. Area under the curve for each model was similar (full model 0.65, clinical model 0.67, RF 0.68, hybrid LR 0.67); however, the hybrid model utilized the fewest variables (18). CONCLUSIONS The hybrid model had similar predictability as other models with fewer and more clinically relevant variables. Machine-learning algorithms can identify important novel characteristics, which enhance clinical prediction models.

Abstract
For decades, safe surgery focused on intraoperative technique and decision-making. The traditional hierarchy placed the surgeon as the leader with ultimate authority and responsibility. Despite the advances in surgical technique and equipment, too many patients have suffered unnecessary complications and suboptimal care. Today, we understand that the conduct of safe and effective surgery requires evidence-based decision-making, multifaceted treatment approaches to prevent complications, and effective communication in and out of the operating room. In this manuscript, we describe three significant advances in quality and safety that have changed the approach to surgical care: the National Surgical Quality Improvement Program, evidence-based bundled prevention of surgical site infections, and the Surgical Safety Checklist.

Abstract
BACKGROUND There is no consensus on optimal timing of gastroschisis repair. The 2012-2014 ACS NSQIP Pediatric Participant Use Data File was used to compare outcomes of primary versus staged gastroschisis repair. METHODS Cases were divided into primary repair (0-1day) and staged repair (4-14days). Baseline characteristics and outcomes were compared for primary versus staged closure using Fisher's exact tests for categorical variables and Wilcoxon rank-sum tests for continuous variables. Length of stay was compared after controlling for prematurity. RESULTS There were 627 subjects included, with 364 neonates in the primary group and 263 in the staged group. The primary group demonstrated shorter hospital length of stay (LOS) (5.1days; p<0.001) and had less surgical site infections (OR=0.27; p=0.003), but had longer ventilator days (1.9days; p<0.001). Neonates in the primary repair group were less likely to be discharged home versus transferred to another hospital (OR=0.24; p=0.006) and more likely to require nutritional support at discharge (OR=1.74; p=0.034). No significant differences were identified for mortality, readmissions, postoperative LOS, sepsis or other outcomes. CONCLUSION Staged repair of gastroschisis has longer LOS attributed to preoperative timing, but less ventilator days. Outcomes for these closure techniques are equivocal and support surgeons performing the closure technique they are most experienced with.

Abstract
BACKGROUND Surgical site infections (SSIs) are a significant healthcare quality issue, resulting in increased morbidity, disability, length of stay, resource utilization, and costs. Identification of high-risk patients may improve pre-operative counseling, inform resource utilization, and allow modifications in peri-operative management to optimize outcomes. METHODS Review of the pertinent English-language literature. RESULTS High-risk surgical patients may be identified on the basis of individual risk factors or combinations of factors. In particular, statistical models and risk calculators may be useful in predicting infectious risks, both in general and for SSIs. These models differ in the number of variables; inclusion of pre-operative, intra-operative, or post-operative variables; ease of calculation; and specificity for particular procedures. Furthermore, the models differ in their accuracy in stratifying risk. Biomarkers may be a promising way to identify patients at high risk of infectious complications. CONCLUSIONS Although multiple strategies exist for identifying surgical patients at high risk for SSIs, no one strategy is superior for all patients. Further efforts are necessary to determine if risk stratification in combination with risk modification can reduce SSIs in these patient populations.

Abstract
BACKGROUND Surgical wound classification (SWC) is used for risk stratification of surgical site infection (SSI) and serves as the basis for measuring quality of care. The objective was to examine the accuracy and reliability of SWC. This study was purposed to evaluate the discrepancies in SWC as assessed by three groups: surgeons, an infection control nurse, and histopathologic evaluation. The secondary aim was to compare the risk-stratified SSI rates using the different SWC methods for 30 d postoperatively. METHODS An analysis was performed of the appendectomies from January 2013 to June 2014 in the Cantonal Hospital of Schaffhausen. SWC was assigned by the operating surgeon at the end of the procedure and retrospectively reviewed by a Swissnoso-trained infection control nurse after reading the operative and pathology report. The level of agreement among the three different SWC assessment groups was determined using kappa statistic. SSI rates were analyzed using a chi-square test. RESULTS In 246 evaluated cases, the kappa scores for interrater reliability among the SWC assessments across the three groups ranged from 0.05 to 0.2 signifying slight agreement between the groups. SSIs were more frequently associated with trained infection control nurse-assigned SWC than with surgeons based SWC. CONCLUSIONS Our study demonstrated a considerable discordance in the SWC assessments performed by the three groups. Unfortunately, the currently practiced SWC system suffers from ambiguity in definition and/or implementation of these definitions is not clearly stated. This lack of reliability is problematic and may lead to inappropriate comparisons within and between hospitals and surgeons.

A multicenter, pediatric quality improvement initiative improves surgical wound class assignment, but is it enough? J Pediatr Surg 2016; 51:639-44. [PMID: 26590473 DOI: 10.1016/j.jpedsurg.2015.10.046] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2015] [Revised: 08/21/2015] [Accepted: 10/10/2015] [Indexed: 11/19/2022]
Abstract
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.

Pediatric surgeon-directed wound classification improves accuracy. J Surg Res 2015; 201:432-9. [PMID: 27020829 DOI: 10.1016/j.jss.2015.11.051] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2015] [Revised: 11/20/2015] [Accepted: 11/25/2015] [Indexed: 11/23/2022]
Abstract
BACKGROUND Surgical wound classification (SWC) communicates the degree of contamination in the surgical field and is used to stratify risk of surgical site infection and compare outcomes among centers. We hypothesized that by changing from nurse-directed to surgeon-directed SWC during a structured operative debrief, we will improve accuracy of documentation. METHODS An institutional review board-approved retrospective chart review was performed. Two time periods were defined: initially, SWC was determined and recorded by the circulating nurse (before debrief, June 2012-May 2013) and allowing 6 mo for adoption and education, we implemented a structured operative debriefing including surgeon-directed SWC (after debrief, January 2014-August 2014). Accuracy of SWC was determined for four commonly performed pediatric general surgery operations: inguinal hernia repair (clean), gastrostomy ± Nissen fundoplication (clean contaminated), appendectomy without perforation (contaminated), and appendectomy with perforation (dirty). RESULTS One hundred eighty-three cases before debrief and 142 cases after debrief met inclusion criteria. No differences between time periods were noted in regard to patient demographics, ASA class, or case mix. Accuracy of wound classification improved before debrief (42% versus 58.5%, P = 0.003). Before debrief, 26.8% of cases were overestimated or underestimated by more than one wound class, versus 3.5% of cases after debrief (P < 0.001). Interestingly, most after debrief contaminated cases were incorrectly classified as clean contaminated. CONCLUSIONS Implementation of a structured operative debrief including surgeon-directed SWC improves the percentage of correctly classified wounds and decreases the degree of inaccuracy in incorrectly classified cases. However, after implementation of the debriefing, we still observed a 41.5% rate of incorrect documentation, most notably in contaminated cases, indicating further education and process improvement is needed.

Abstract
BACKGROUND Surgical wound classification (SWC) is a component of surgical site infection risk stratification. Studies have demonstrated that SWC is often incorrectly documented. This study examines the accuracy of SWC after implementation of a multifaceted plan targeted at accurate documentation. METHODS A reviewer examined operative notes of 8 pediatric operations and determined SWC for each case. This SWC was compared with nurse-documented SWC. Percent agreement pre- and postintervention was compared. Analysis was performed using chi-square and a P value less than .05 was significant. RESULTS Preintervention concordance was 58% (112/191) and postintervention was 83% (163/199, P = .001). Appendectomy accuracy was 28% and increased to 80% (P = .0005). Fundoplication accuracy increased from 44% to 84% (P = .016) and gastrostomy tube from 56% to 100% (P = .0002). The most accurate operation preintervention was pyloromyotomy and postintervention was gastrostomy tube and inguinal hernia. The least accurate pre- and postintervention was cholecystectomy. CONCLUSION Implementation of a multifaceted approach improved accuracy of documented SWC.

Surgical wound classification for pediatric appendicitis remains poorly documented despite targeted interventions. J Pediatr Surg 2015; 50:915-8.

Abstract
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.

Abstract
BACKGROUND Ventral incisional hernias (VIH) develop in up to 20% of patients after abdominal surgery. No widely applicable preoperative risk-assessment tool exists. We aimed to develop and validate a risk-assessment tool to predict VIH after abdominal surgery. STUDY DESIGN A prospective study of all patients undergoing abdominal surgery was conducted at a single institution from 2008 to 2010. Variables were defined in accordance with the National Surgical Quality Improvement Project, and VIH was determined through clinical and radiographic evaluation. A multivariate Cox proportional hazard model was built from a development cohort (2008 to 2009) to identify predictors of VIH. The HERNIAscore was created by converting the hazards ratios (HR) to points. The predictive accuracy was assessed on the validation cohort (2010) using a receiver operator characteristic curve and calculating the area under the curve (AUC). RESULTS Of 625 patients followed for a median of 41 months (range 0.3 to 64 months), 93 (13.9%) developed a VIH. The training cohort (n = 428, VIH = 70, 16.4%) identified 4 independent predictors: laparotomy (HR 4.77, 95% CI 2.61 to 8.70) or hand-assisted laparoscopy (HAL, HR 4.00, 95% CI 2.08 to 7.70), COPD (HR 2.35; 95% CI 1.44 to 3.83), and BMI ≥ 25 kg/m(2) (HR1.74; 95% CI 1.04 to 2.91). Factors that were not predictive included age, sex, American Society of Anesthesiologists (ASA) score, albumin, immunosuppression, previous surgery, and suture material or technique. The predictive score had an AUC = 0.77 (95% CI 0.68 to 0.86) using the validation cohort (n = 197, VIH = 23, 11.6%). Using the HERNIAscore: HERNIAscore = 4(∗)Laparotomy+3(∗)HAL+1(∗)COPD+1(∗) BMI ≥ 25, 3 classes stratified the risk of VIH: class I (0 to 3 points),5.2%; class II (4 to 5 points),19.6%; and class III (6 points), 55.0%. CONCLUSIONS The HERNIAscore accurately identifies patients at increased risk for VIH. Although external validation is needed, this provides a starting point to counsel patients and guide clinical decisions. Increasing the use of laparoscopy, weight-loss programs, community smoking prevention programs, and incisional reinforcement may help reduce rates of VIH.

Percutaneous versus femoral cutdown access for endovascular aneurysm repair. J Vasc Surg 2015; 62:16-21. [PMID: 25827969 DOI: 10.1016/j.jvs.2015.01.058] [Citation(s) in RCA: 91] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2014] [Accepted: 01/29/2015] [Indexed: 12/17/2022]
Abstract
OBJECTIVE Prior studies suggest that percutaneous access for endovascular abdominal aortic aneurysm repair (pEVAR) offers significant operative and postoperative benefits compared with femoral cutdown (cEVAR). National data on this topic, however, are limited. We compared patient selection and outcomes for elective pEVAR and cEVAR. METHODS We identified all patients undergoing either pEVAR (bilateral percutaneous access, whether successful or not) or cEVAR (at least one planned groin cutdown) for abdominal aortic aneurysms from January 2011 to December 2013 in the Targeted Vascular data set from the American College of Surgeons National Surgical Quality Improvement Program database. Emergent cases, ruptures, cases with an iliac conduit, and cases with a preoperative wound infection were excluded. Groups were compared by χ(2) test or t-test or the Mann-Whitney test where appropriate. RESULTS We identified 4112 patients undergoing elective EVAR, 3004 cEVAR patients (73%) and 1108 pEVAR patients (27%). Of all EVAR patients, 26% had bilateral percutaneous access; 1.0% had attempted percutaneous access converted to cutdown (4% of pEVARs); and the remainder had a planned cutdown, 63.9% bilateral and 9.1% unilateral. There were no significant differences in age, gender, aneurysm diameter, or prior open abdominal surgery. Patients undergoing cEVAR were less likely to have congestive heart failure (1.5% vs 2.4%; P = .04) but more likely to undergo any concomitant procedure during surgery (32% vs 26%; P < .01) than patients undergoing pEVAR. Postoperatively, pEVAR patients had shorter operative time (mean, 135 vs 152 minutes; P < .01), shorter length of stay (median, 1 day vs 2 days; P < .01), and fewer wound complications (2.1% vs 1.0%; P = .02). On multivariable analysis, the only predictor of percutaneous access failure was performance of any concomitant procedure (odds ratio, 2.0; 95% confidence interval, 1.0-4.0; P = .04). CONCLUSIONS Currently, one in four patients treated at Targeted Vascular National Surgical Quality Improvement Program centers are getting pEVAR, which is associated with a high success rate, shorter operation time, shorter length of stay, and fewer wound complications compared with cEVAR.
