ABSTRACT

OBJECTIVE: To develop a severity-adjusted, hospital-level benchmarking comparative performance report for postoperative organ space infection and antibiotic utilization in children with complicated appendicitis. BACKGROUND: No benchmarking data exist to aid hospitals in identifying and prioritizing opportunities for infection prevention or antimicrobial stewardship in children with complicated appendicitis. METHODS: This was a multicenter cohort study using NSQIP-Pediatric data from 16 hospitals participating in a regional research consortium, augmented with antibiotic utilization data obtained through supplemental chart review. Children with complicated appendicitis who underwent appendectomy from 07/01/2015 to 06/30/2020 were included. Thirty-day postoperative OSI rates and cumulative antibiotic utilization were compared between hospitals using observed-to-expected (O/E) ratios after adjusting for disease severity using mixed effects models. Hospitals were considered outliers if the 95% confidence interval for O/E ratios did not include 1.0. RESULTS: 1790 patients were included. Overall, the OSI rate was 15.6% (hospital range: 2.6-39.4%) and median cumulative antibiotic utilization was 9.0 days (range: 3.0-13.0). Across hospitals, adjusted O/E ratios ranged 5.7-fold for OSI (0.49-2.80, P=0.03) and 2.4-fold for antibiotic utilization (0.59-1.45, P<0.01). Three (19%) hospitals were outliers for OSI (1 high and 2 low performers), and eight (50%) were outliers for antibiotic utilization (5 high and 3 low utilizers). Ten (63%) hospitals were identified as outliers in one or both measures. CONCLUSIONS: A comparative performance benchmarking report may help hospitals identify and prioritize quality improvement opportunities for infection prevention and antimicrobial stewardship, as well as identify exemplar performers for dissemination of best practices.

ABSTRACT

BACKGROUND: The objective was to explore the hospital-level relationship between routine pre-discharge WBC utilization (RPD-WBC) and outcomes in children with complicated appendicitis. METHODS: Multicenter analysis of NSQIP-Pediatric data from 14 consortium hospitals augmented with RPD-WBC data. WBC were considered routine if obtained within one day of discharge in children who did not develop an organ space infection (OSI) or fever during the index admission. Hospital-level observed-to-expected ratios (O/E) for 30-day outcomes (antibiotic days, imaging utilization, healthcare days, and OSI) were calculated after adjusting for appendicitis severity and patient characteristics. Spearman correlation was used to explore the relationship between hospital-level RPD-WBC utilization and O/E's for each outcome. RESULTS: 1528 children were included. Significant variation was found across hospitals in RPD-WBC use (range: 0.7-100%; p < 0.01) and all outcomes (mean antibiotic days: 9.9 [O/E range: 0.56-1.44, p < 0.01]; imaging: 21.9% [O/E range: 0.40-2.75, p < 0.01]; mean healthcare visit days: 5.7 [O/E 0.74-1.27, p < 0.01]); OSI: 14.1% [O/E range: 0.43-3.64, p < 0.01]). No correlation was found between RPD-WBC use and antibiotic days (r = +0.14, p = 0.64), imaging (r = -0.07, p = 0.82), healthcare days (r = +0.35, p = 0.23) or OSI (r = -0.13, p = 0.65). CONCLUSIONS: Increased RPD-WBC utilization in pediatric complicated appendicitis did not correlate with improved outcomes or resource utilization at the hospital level. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Clinical Research.

ABSTRACT

OBJECTIVE: To evaluate whether redosing antibiotics within an hour of incision is associated with a reduction in incisional surgical site infection (iSSI) in children with appendicitis. BACKGROUND: Existing data remain conflicting as to whether children with appendicitis receiving antibiotics at diagnosis benefit from antibiotic redosing before incision. METHODS: This was a multicenter retrospective cohort study using data from the Pediatric National Surgical Quality Improvement Program augmented with antibiotic utilization and operative report data obtained though supplemental chart review. Children undergoing appendectomy at 14 hospitals participating in the Eastern Pediatric Surgery Network from July 2016 to June 2020 who received antibiotics upon diagnosis of appendicitis between 1 and 6 hours before incision were included. Multivariable logistic regression was used to compare odds of iSSI in those who were and were not redosed with antibiotics within 1 hour of incision, adjusting for patient demographics, disease severity, antibiotic agents, and hospital-level clustering of events. RESULTS: A total of 3533 children from 14 hospitals were included. Overall, 46.5% were redosed (hospital range: 1.8%-94.4%, P <0.001) and iSSI rates were similar between groups [redosed: 1.2% vs non-redosed: 1.3%; odds ratio (OR) 0.84, (95%,CI, 0.39-1.83)]. In subgroup analyses, redosing was associated with lower iSSI rates when cefoxitin was used as the initial antibiotic (redosed: 1.0% vs nonredosed: 2.5%; OR: 0.38, (95% CI, 0.17-0.84)], but no benefit was found with other antibiotic regimens, longer periods between initial antibiotic administration and incision, or with increased disease severity. CONCLUSIONS: Redosing of antibiotics within 1 hour of incision in children who received their initial dose within 6 hours of incision was not associated with reduction in risk of incisional site infection unless cefoxitin was used as the initial antibiotic.

ABSTRACT

Importance: The clinical significance of gangrenous, suppurative, or exudative (GSE) findings is poorly characterized in children with nonperforated appendicitis. Objective: To evaluate whether GSE findings in children with nonperforated appendicitis are associated with increased risk of surgical site infections and resource utilization. Design, Setting, and Participants: This multicenter cohort study used data from the Appendectomy Targeted Database of the American College of Surgeons Pediatric National Surgical Quality Improvement Program, which were augmented with operative report data obtained by supplemental medical record review. Data were obtained from 15 hospitals participating in the Eastern Pediatric Surgery Network (EPSN) research consortium. The study cohort comprised children (aged ≤18 years) with nonperforated appendicitis who underwent appendectomy from July 1, 2015, to June 30, 2020. Exposures: The presence of GSE findings was established through standardized, keyword-based audits of operative reports by EPSN surgeons. Interrater agreement for the presence or absence of GSE findings was evaluated in a random sample of 900 operative reports. Main Outcomes and Measures: The primary outcome was 30-day postoperative surgical site infections (incisional and organ space infections). Secondary outcomes included rates of hospital revisits, postoperative abdominal imaging, and postoperative length of stay. Multivariable mixed-effects regression was used to adjust measures of association for patient characteristics and clustering within hospitals. Results: Among 6133 children with nonperforated appendicitis, 867 (14.1%) had GSE findings identified from operative report review (hospital range, 4.2%-30.2%; P < .001). Reviewers agreed on presence or absence of GSE findings in 93.3% of cases (weighted κ, 0.89; 95% CI, 0.86-0.92). In multivariable analysis, GSE findings were associated with increased odds of any surgical site infection (4.3% vs 2.2%; odds ratio [OR], 1.91; 95% CI, 1.35-2.71; P < .001), organ space infection (2.8% vs 1.1%; OR, 2.18; 95% CI, 1.30-3.67; P = .003), postoperative imaging (5.8% vs 3.7%; OR, 1.70; 95% CI, 1.23-2.36; P = .002), and prolonged mean postoperative length of stay (1.6 vs 0.9 days; rate ratio, 1.43; 95% CI, 1.32-1.54; P < .001). Conclusions and Relevance: In children with nonperforated appendicitis, findings of gangrene, suppuration, or exudate are associated with increased surgical site infections and resource utilization. Further investigation is needed to establish the role and duration of postoperative antibiotics and inpatient management to optimize outcomes in this cohort of children.

ABSTRACT

BACKGROUND: Popliteal artery injury is associated with a high risk of limb loss; identifying factors associated with increased morbidity and mortality is hampered by its rare occurrence and confounding factors. Anecdotal observations suggest delay in diagnosis of obese patients may be associated with amputation. We aimed to determine whether there is an increased risk of early amputation and if diagnosis is delayed in obese patients with popliteal artery injuries. METHODS: We conducted a retrospective cohort study using National Trauma Data Bank (NTDB) data from 2013 to 2017. We extracted those sustaining popliteal artery injury, assigning obesity class based on body mass index. We included select demographic and clinical variables, using time to imaging as a surrogate for time to diagnosis. Statistical models were used to calculate the impact of obesity on amputation rates and time to diagnosis. RESULTS: We identified 4803 popliteal artery injuries in the data set; 3289 met inclusion criteria. We calculated an 8.5% overall amputation rate, which was not significantly different between obese (N = 1305; 39.7%) and nonobese (N = 1984; 60.3%) patients. Statistical analysis identified peripheral vascular disease, diabetes, and smoking as risk factors for amputation. Time to imaging was similar for obese and nonobese patients. CONCLUSIONS AND RELEVANCE: Analysis of NTDB data suggests that obesity is associated with neither increased early amputation rate nor longer time to imaging in patients with popliteal artery injury. However, our study suggests that underlying comorbidities of peripheral vascular disease and diabetes are associated with an increased risk for amputation in these patients.

ABSTRACT

INTRODUCTION: When it is not possible to capture direct measures of occupational exposure or conduct biomonitoring, retrospective exposure assessment methods are often used. Among the common retrospective assessment methods, assigning exposure estimates by multiple expert rater review of detailed job descriptions is typically the most valid, but also the most time-consuming and expensive. Development of screening protocols to prioritize a subset of jobs for expert rater review can reduce the exposure assessment cost and time requirement, but there is often little data with which to evaluate different screening approaches. We used existing job-by-job exposure assessment data (assigned by consensus between multiple expert raters) from a large, population-based study of women to create and test screening algorithms for polycyclic aromatic hydrocarbons (PAHs) that would be suitable for use in other population-based studies. METHODS: We evaluated three approaches to creating a screening algorithm: a machine-learning algorithm, a set of a priori decision rules created by experts based on features (such as keywords) found in the job description, and a hybrid algorithm incorporating both sets of criteria. All coded jobs held by mothers of infants participating in National Birth Defects Prevention Study (NBDPS) (n = 35,424) were used in developing or testing the screening algorithms. The job narrative fields considered for all approaches included job title, type of product made by the company, main activities or duties, and chemicals or substances handled. Each screening approach was evaluated against the consensus rating of two or more expert raters. RESULTS: The machine-learning algorithm considered over 30,000 keywords and industry/occupation codes (separate and in combination). Overall, the hybrid method had a similar sensitivity (87.1%) as the expert decision rules (85.5%) but was higher than the machine-learning algorithm (67.7%). Specificity was best in the machine-learning algorithm (98.1%), compared to the expert decision rules (89.2%) and hybrid approach (89.1%). Using different probability cutoffs in the hybrid approach resulted in improvements in sensitivity (24-30%), without the loss of much specificity (7-18%). CONCLUSION: Both expert decision rules and the machine-learning algorithm performed reasonably well in identifying the majority of jobs with potential exposure to PAHs. The hybrid screening approach demonstrated that by reviewing approximately 20% of the total jobs, it could identify 87% of all jobs exposed to PAHs; sensitivity could be further increased, albeit with a decrease in specificity, by adjusting the algorithm. The resulting screening algorithm could be applied to other population-based studies of women. The process of developing the algorithm also provides a useful illustration of the strengths and potential pitfalls of these approaches to developing exposure assessment algorithms.

ABSTRACT

OBJECTIVE: The use of the da Vinci Robot has been fast growing in general surgery in the United States over the past decade. While the financial cost of robot-assisted procedures has been studied, there has been limited research on the educational cost of the robotic approach on general surgery trainees, and their surgical skills. DESIGN: Analysis of anonymous educational survey responses collected from residents, in addition to case logs which were used as a retrospective review for the 5 years preceding the survey. SETTING: One thousand bed, tertiary care hospital general surgery residency program. PARTICIPANTS: Twenty-four enrolled general surgery residents in 2018. RESULTS: There has been a rapid expansion in the use of robotics in general surgery. In 2017 the total number of general surgery cases using the da Vinci robot increased 6 fold over that in 2013 (23 cases in 2013, 136 in 2017), while both open and laparoscopic procedures have witnessed about a 33% drop in the case volume during those years. Almost all residents would prefer a residency program which offers the da Vinci robot for care and training (95%), however, 38% of general surgery residents reported that the presence of robotic-assisted surgery had a "detrimental" effect on their surgical training. Senior residents were more likely to report a "detrimental" effect (56% vs 27%). A third of the residents believe that robotic surgery is impeding their ability to learn open and laparoscopic surgical techniques, and only 25% denied a negative impact. Senior residents are more likely to report this negative impact (67% vs 13%). CONCLUSIONS: Reforms in residency curricula need to be in place to accommodate the expansion of the use of the robotic platform in general surgery. A subjective survey of the residents suggests that robotic surgery can potentially impede the development of residents' open and laparoscopic surgical skills.

ABSTRACT

Minimally invasive surgery (MIS) is favored for T1-T3 colon cancer resection due to improved short and long-term outcomes. Recommendations regarding T4 cancers remain controversial due to a paucity of clinical trials or large datasets assessing outcomes. We aim to compare outcomes for pT4 colon cancer patients treated with MIS or open surgery (OS) in the National Cancer Database (NCDB). We analyzed adults having MIS or OS for stage II or III pT4 colon cancers between 2010 and 2014 using propensity-score matching, Cox and logistic regression modeling. Of 21 998 T4 patients, 7532 (34.2%) underwent MIS, 14 466 (65.8%) OS and 22.3% were MIS converted to OS. After propensity score matching, 5624 patients in each cohort were included. MIS was associated with improved postoperative mortality (3.4 vs. 7.2%, p > .001), surgical margins, optimal lymph node harvest, adjuvant chemotherapy use and 5-year survival (46% vs. 41%, P < .001). MIS was associated with improved short and long term outcomes for T4 colon cancers compared to OS on multivariate analysis. Based on these findings, well selected pT4 colon cancers can be considered appropriate for MIS however, prospective clinical trials are needed to better define the role of MIS in T4b colon cancer.

ABSTRACT

OBJECTIVE: The primary purpose of this study was to examine any potential difference in clinical outcomes between transcarotid artery revascularization performed under local anesthesia compared with general anesthesia by utilizing a large national database. METHODS: The primary outcome of the study was a composite endpoint of postoperative in-hospital stroke, myocardial infarction and mortality following transcarotid artery revascularization for the index procedure. Secondary outcomes included a composite outcome of postoperative in-hospital stroke, transient ischemic attack, myocardial infarction and mortality along with several subsets of its components and each individual component, flow reversal time (min), radiation dose (GY/cm2), contrast volume utilized (mL), total procedure time (min), extended total length of stay (>1 day) and extended postoperative length of stay (>1 day). Statistical analyses employed both descriptive measures to characterize the study population and analytic measures such as multivariable mixed-effect linear and logistic regressions using both unmatched and propensity-score matched cohorts. RESULTS: A total of 2609 patients undergoing transcarotid artery revascularization between the years 2016 and 2018 in the US were identified, with 82.3% performed under general anesthesia and 17.7% under local anesthesia. The primary composite outcome was observed in 2.3% of general anesthesia patients versus 2.6% of local anesthesia patients (p = 0.808). The rate of postoperative transient ischemic attack and/or myocardial infarction was 1.6% with general anesthesia versus 1.1% with local anesthesia (p = 0.511). For adjusted regression analysis, general anesthesia and local anesthesia were comparable in terms of primary outcome (OR: 0.72; 95% CI: 0.27-1.93, p = 0.515). As for the secondary outcomes, no significant differences were found except for contrast, where the results demonstrated significantly less need for contrast with procedures performed under general anesthesia (coefficient: 4.94; 95% CI: 1.34-8.54, p = 0.007). A trend towards significance was observed for lower rate of postoperative transient ischemic attack and/or myocardial infarction (OR: 0.33; 95% CI: 0.09-1.18, p = 0.088) and lower flow reversal time under local anesthesia (coefficient: -0.94: 95% CI: -2.1-0.22, p = 0.111). CONCLUSIONS: Excellent outcomes from transcarotid artery revascularization for carotid stenosis were observed in the VQI database between the years 2016 and 2018, under both local anesthesia and general anesthesia. The data demonstrate the choice of anesthesia for transcarotid artery revascularization does not appear to have any effect on clinical outcomes. Surgical teams should perform transcarotid artery revascularization under the anesthesia type they are most comfortable with.

ABSTRACT

Extracranial internal carotid artery (ICA) aneurysms account for <1.0% all aneurysms and a rare indication for carotid intervention. Causes include atherosclerotic degeneration, trauma, dissection, previous carotid surgery, connective tissue disorders, and infection. Authors report a case of a middle-aged male found to have a large aneurysm of the left ICA who underwent repair by resection and reconstruction with end-to-end anastomosis under neuroprotection with flow reversal. Our discussion includes a recommendation for this particular surgical repair. The patient in this case report has granted the authors consent for review of records and subsequent publication submission.

ABSTRACT

BACKGROUND: Minimally invasive techniques have become standard approaches for many common surgical problems. However, the routine use of laparoscopy in the management of small bowel obstruction (SBO) has yet to be fully standardized. The objective of this study was to determine clinical factors associated with success of laparoscopy in managing SBO. METHODS: A retrospective cohort study was conducted by identifying all patients admitted to a large tertiary center with a diagnosis of SBO from 2014 to 2016. The operative cases were stratified by surgical approach: laparoscopy, laparoscopy converted to open, or laparotomy. Univariable analysis compared patient demographics and comorbidities between the laparoscopic and laparoscopic converted to open group. The primary outcome was successful laparoscopic procedure in the management of SBO, defined as resolution of SBO, and no conversion from laparoscopic to open procedures. Student's t test or Pearson's χ2 test were used to assess associations between factors and primary outcome. RESULTS: A total of 227 adult patients admitted with a diagnosis of SBO received operative intervention. There were 40 successful laparoscopic cases (52.6%) and 36 failed laparoscopic cases (47.4%). With the exception of an association between success of laparoscopy and BMI, the results demonstrated no other demographic or clinical differences among the successful versus failed laparoscopic groups. CONCLUSIONS: Laparoscopy is effective in treating SBOs due to various etiologies including single band or multiple adhesions, hernias, or masses. Other than BMI, there was no single predictor of success or failure with laparoscopy. Therefore, we conclude that perhaps all patients requiring operative treatment for SBO deserve consideration for a diagnostic laparoscopy.

ABSTRACT

Acute mesenteric ischemia secondary to aortic dissection in type A and type B is a true vascular surgical emergency. Presentation can be subtle or dramatic, and time to revascularization is limited before irreversible changes occur. The literature recognizes the catastrophic consequences of acute superior mesenteric artery occlusion and the need for urgent revascularization, often before central aortic repair in type A. There is no optimal revascularization technique described in this scenario. We present a case of type A aortic dissection with acute dynamic and static superior mesenteric artery occlusion and describe treatment that resulted in successful salvage of the bowel and the patient's life.

ABSTRACT

OBJECTIVES: Mammalian targets of rapamycin inhibitors (mTORi) are considered second-line immunosuppression agents because of associated increases in rejection and impaired wound healing. Recent reports indicate mTORi have been linked to improved survival, decreased inflammatory response in pancreatitis, and antiproliferative and antiangiogenic activity. Mammalian targets of rapamycin inhibitors have not been extensively analyzed in pancreas transplant recipients. METHODS: Adults with pancreas and kidney-pancreas transplants from 1987 to 2016 in the United Network for Organ Sharing database were analyzed (N = 25,837). Subjects were stratified into 2 groups: use of mTORi (n = 4174) and use of non-mTORi-based immunosuppression (n = 21,663). The log-rank test compared survival rates. Univariate and multivariate Cox regression analyses assessed patient and graft survival. RESULTS: Mammalian targets of rapamycin inhibitors were associated with a 7% risk reduction in allograft failure (hazard ratio, 0.931; P = 0.006). Allograft survival rates were significantly different between mTORi versus non-mTORi (P < 0.0001).The mTORi group showed a significantly higher patient survival rate 1, 3, 5, and 10 years posttransplant compared. Patient survival at 15 years was not significantly different. CONCLUSIONS: The use of mTORi for immunosuppression in pancreas transplant is associated with improved allograft survival and early patient survival posttransplant (up to 10 years).

ABSTRACT

Outpatient use of atherectomy for peripheral arterial disease has grown rapidly and outcomes are poorly understood. We analyzed outcomes of atherectomy done for claudication, comparing office and hospital outpatient settings. Analysis of Medicare Part B claims data was performed for incident femoral-popliteal or tibial-peroneal atherectomy from 2012 to 2014. Longitudinal analysis assessed services 18 months before, during, and up to 18 months after the incident peripheral vascular intervention (PVI). Differences between office-based and hospital outpatient-based settings were assessed using χ2 and Fisher exact tests. Comparing procedure settings, significant differences in race (femoral-popliteal: P = .04, tibial-peroneal: P = .001), chronic renal failure (femoral-popliteal: P = .002), and hypertension (femoral-popliteal: P = .01, tibial-peroneal: P = .006) were found. Nine hundred twenty-four patients undergoing femoral-popliteal atherectomy were analyzed (262 office based, 662 hospital outpatient based); 42.7% of office-based and 36.9% of hospital outpatient-based femoral-popliteal atherectomy patients had repeat PVI within 18 months ( P = .10). Major amputation was performed in 2.3% and 3.2% of patients in office and hospital outpatient settings, respectively ( P = .47). Four hundred twenty-three patients undergoing tibial-peroneal atherectomy were analyzed (202 office based, 221 hospital outpatient based); 46.5% of office-based and 38.9% of hospital outpatient-based tibial-peroneal atherectomy patients had repeat PVI within 1 year ( P = .11). Major amputation was performed in 5.0% and 8.1% of patients in office and hospital outpatient settings, respectively ( P = .19). Our study demonstrates higher than expected rates of major amputation for patients undergoing peripheral arterial atherectomy with regard to previously reported rates. Further studies may be required to prove the efficacy and safety of atherectomy for occlusive disease in the femoral-popliteal and tibial-peroneal segments to ensure outcomes are not worse than the natural history of medically managed claudicants.

ABSTRACT

OBJECTIVES: Our institution implemented a protocol known as thoracic enhanced recovery with ambulation after surgery (T-ERAS) in thoracic operations. The objective was early ambulation starting in the postoperative ambulatory care unit. METHODS: Video-assisted thoracoscopic surgery lobectomy patients are placed on a chair in the preoperative area and then walked to the operating room. Postoperatively, patients are placed on a chair as soon as possible. Our target ambulation goal was 250 feet within 1 h of extubation. Patients then walk to their hospital room. T-ERAS adoption and outcomes were compared to a pre-T-ERAS period, in addition to the comparing early and late T-ERAS cohorts. RESULTS: Over 6 years, 304 patients on T-ERAS underwent a planned video-assisted thoracoscopic surgery lobectomy. Median age was 67 years (range 41-87 years). The target goal was achieved in 187 of 304 (61.5%) patients and 277 of 304 (91.1%) patients ambulated 250 feet at any time in the postoperative ambulatory care unit. The T-ERAS period had a median length of stay of 1 day vs 2 days in the pre-T-ERAS period (P < 0.001). There were low rates of pneumonia (2/304, 0.7%), atrial fibrillation (12/304, 4.0%) and no postoperative mortalities for T-ERAS. The target goal was achieved at a greater rate in the late (92/132, 72.0%) versus early (28/75, 37%) T-ERAS cohort. The mean time to ambulation was reduced in the late cohort (46-81 min). CONCLUSIONS: Early postoperative ambulation was feasible and considered key in achieving low morbidity after video-assisted thoracoscopic surgery lobectomy. Adoption of T-ERAS improved over time. Further studies will help define adoptability at other sites and validate impact on improving outcomes.
