Abstract Background There is still a lack of relevant studies on surgical site infection (SSI) after emergency abdominal surgery (EAS) in China. This study aims to understand the status of SSI after EAS in China and discuss its risk factors. Materials and Methods All adult patients who underwent EAS in 47 hospitals in China from May 1 to 31, 2018, and from May 1 to June 7, 2019, were enrolled in this study. The basic information, perioperative data, and microbial culture results of infected incision were prospectively collected.The primary outcome measure was the incidence of SSI after EAS, and the secondary outcome variables were postoperative length of stay, ICU admission rate, ICU length of stay, 30-day postoperative mortality, and treatment costs. Univariate and multivariate logistic regression were used to analyze the risk factors.Results A total of 953 patients (age 48.8 ± 17.9 years, male 51.9%) with EAS were included in this study: 71 patients (7.5%) developed SSI after surgery.The main pathogen of SSI was Escherichia coli (culture positive rate 29.6%). Patients with SSI had significantly longer overall hospital (p < 0.001) and ICU stays (p < 0.001), significantly higher ICU admissions (p < 0.001), and medical costs (p < 0.001) than patients without SSI.Multivariate logistic regression analysis showed that male (P = 0.010), high blood glucose level (P < 0.001), colorectal surgery (P < 0.001), intestinal obstruction (P = 0.045) and surgical duration (P = 0.007) were risk factors for SSI, whereas laparoscopic surgery (P < 0.001 = 0.022) was a protective factor. Conclusion This study found a high incidence of SSI after EAS in China. The occurrence of SSI prolongs the patient's hospital stay and increases the medical burden. The study also revealed predictors of SSI after EAS and provides a basis for the development of norms for the prevention of surgical site infection after emergency abdominal surgery.

Univariate and multivariate logistic regression were used to analyze the risk factors. The results were expressed as the odds ratio and 95% confidence interval. A total of 953 patients [age 48.8 (SD: 17.9), male 51.9%] with EAS were included in this study: 71 patients (7.5%) developed SSI after surgery. The main pathogen of SSI was Escherichia coli (culture positive rate 29.6%). Patients with SSI had significantly longer overall hospital (p < 0.001) and ICU stays (p < 0.001), significantly higher ICU admissions (p < 0.001), and medical costs (p < 0.001) than patients without SSI. Multivariate logistic regression analysis showed that male (P = 0.010), high blood glucose level (P < 0.001), colorectal surgery (P < 0.001), intestinal obstruction (P = 0.045) and surgical duration (P = 0.007) were risk factors for SSI, whereas laparoscopic surgery (P < 0.001) was a protective factor. This study found a high incidence of SSI after EAS in China. The occurrence of SSI prolongs the patient's hospital stay and increases the medical burden.

Abstract Background Exploratory laparotomy surgery is abdominal operations not involving the gastrointestinal tract or biliary system. The objective of our study is to answer three questions: (a) What is the risk of surgical site infection (SSI) after exploratory abdominal surgery? (b) What is the impact of SSI in the hospital length of stay and hospital mortality? (c) What are risk factors for SSI after exploratory abdominal surgery? Methods A retrospective cohort study assessed meningitis and risk factors in patients undergoing exploratory laparotomy between January 2013 and December 2017 from 12 hospitals at Belo Horizonte, Brazil. Data were gathered by standardized methods defined by the National Healthcare Safety Network (NHSN)/CDC procedure-associated protocols for routine SSI surveillance. 26 preoperative and operative categorical and continuous variables were evaluated by univariate and multivariate analysis (logistic regression). Outcome variables: Surgical site infection (SSI), hospital death, hospital length of stay. Variables were analyzed using Epi Info and applying statistical two-tailed test hypothesis with significance level of 5%. Results A sample of 6,591 patients submitted to exploratory laparotomy was analyzed (SSI risk = 4.3%): Hospital length of stay in noninfected patients (days): mean = 16, median = 6, std. dev. = 30; hospital stay in infected patients: mean = 32, median = 22, std. dev. = 30 (P < 0.001). The mortality rate in patients without infection was 14% while hospital death of infected patients was 20% (P = 0.009). Main risk factors for SSI: ügeneral anesthesia (SSI = 4.9%, relative risk – RR = 2.8, P < 0.001); preoperative hospital length of stay more than 4 days (SSI=3.9%, RR=1.8, P = 0.003); wound class contaminated or dirty (SSI = 5.4%, RR = 1.5, P = 0.002); duration of procedure higher than 3 hours (SSI = 7.1%, RR = 2.1, P < 0.001); after trauma laparotomy (SSI = 7.8%, RR = 1.9, P = 0.001). Conclusion We identified patients at high risk of surgical site infection after exploratory laparotomy: trauma patients from contaminated or dirty wound surgery, submitted to a procedure with general anesthesia that last more than 3 hours have 13% SSI. Patients without any of these four risk factors have only 1.2% SSI. Disclosures All authors: No reported disclosures.

A prospective, multicenter, randomized controlled trial found that four days of antibiotics for source-controlled complicated intra-abdominal infection resulted in similar outcomes when compared with a longer duration. We hypothesized that patients with specific risk factors for complications also had similar outcomes. Short-course patients with obesity, diabetes, or Acute Physiology and Chronic Health Evaluation II ≥15 from the STOP-IT trial were compared with longer duration patients. Outcomes included incidence of and days to infectious complications, mortality, and length of stay. Obese and diabetic patients had similar incidences of and days to surgical site infection, recurrent intra-abdominal infection, extra-abdominal infection, and Clostridium difficile infection. Short- and long-course patients had similar incidences of complications among patients with Acute Physiology and Chronic Health Evaluation II ≥15. However, there were fewer days to the diagnosis of surgical site infection (9.5 ± 3.4 vs 21.6 ± 6.2, P = 0.010) and extra-abdominal infection (12.4 ± 6.9 vs 21.8 ± 6.1, P = 0.029) in the short-course group. Mortality and length of stay was similar for all groups. A short course of antibiotics in complicated intraabdominal infection with source control seems to have similar outcomes to a longer course in patients with diabetes, obesity, or increased severity of illness.

Introduction Surgical site infection (SSI) is a key performance indicator to assess the quality of surgical care. Incidence and risk factors for SSI in neonatal surgery are lacking in the literature. Aim To define the incidence of SSI and possible risk factors in a tertiary neonatal surgery centre. Materials and Methods This is a prospective cohort study of all the neonates who underwent abdominal and thoracic surgery between March 2012 and October 2016. The variables analyzed were gender, gestational age, birth weight, age at surgery, preoperative stay in neonatal intensive care unit, type of surgery, length of stay, and microorganisms isolated from the wounds. Statistical analysis was done with chi-square, Student's t- or Mann–Whitney U-tests. A logistic regression model was used to evaluate determinants of risk for SSI; variables were analyzed both with univariate and multivariate models. For the length of hospital stay, a logistic regression model was performed with independent variables. Results A total of 244 neonates underwent 319 surgical procedures. The overall incidence of SSIs was 43/319 (13.5%). The only statistical differences between neonates with and without SSI were preoperative stay (<4 days vs. ≥4 days, p < 0.01) and length of hospital stay (<30 days vs. ≥30 days, p < 0.01). A pre-operative stay longer than 4 days was associated with almost three times increased risk of SSI (odds ratio [OR] 2.96, 95% confidence interval [CI] 1.05–8.34, p = 0.0407). Gastrointestinal procedures were associated with more than ten times the risk of SSI compared with other procedures (OR 10.17, 95% CI 3.82–27.10, p < 0.0001). Gastroschisis closure and necrotizing enterocolitis (NEC) laparotomies had the highest incidence SSI (54% and 62%, respectively). The risk of longer length of hospital stay after SSI was more than three times higher (OR = 3.36, 95%CI 1.63–6.94, p = 0.001). Conclusion This is the first article benchmarking the incidence of SSI in neonatal surgery in the United Kingdom. A preoperative stay ≥4 days and gastrointestinal procedures were independent risk factors for SSI. More research is needed to develop strategies to reduce SSI in selected neonatal procedures.

Background Emergency open large bowel procedures have higher rates of intraoperative contamination and increased risk of surgical site infection (SSI) than elective colon surgeries. Several wound management strategies have been proposed, such as vacuum-assisted closure (VAC) therapy and delayed primary closure to improve results. The purpose of this study is to evaluate the relationship between wound management technique and SSI and other quality measures. Methods We performed a retrospective review of patients undergoing open emergency colon surgery from January 2017 to December 2018 by our acute care surgery service. The primary outcome measure was incidence of SSI. Secondary outcome measures included length of stay, reoperation, and 30-day readmission. Results A total of 118 patients were included in the study, with a mean age of 62.8 years and mean BMI of 28.8. Overall incidence of SSI was 19.5%. There was no significant difference in incidence of SSI, reoperation, or 30-day readmission when stratifying by wound management technique or procedure type after controlling for confounding variables. Notably, patients managed with VAC therapy had a statistically significant longer average length of stay and higher total postoperative antibiotic days (both P = .001) than other techniques. Discussion We conclude from our data that wound management technique does not seem to influence rate of SSI, but wound management may influence length of stay or antibiotic duration. These findings suggest that there may not be an advantage to alternative methods of wound management in this high-risk population. Further prospective evaluation should be performed to confirm these findings.

BackgroundOrgan/space surgical site infection (organ/space SSI) is a serious postoperative complication, closely related to a poor prognosis. Few studies have attempted to stratify the risk of organ/space SSI for patients with advanced digestive system cancer. This study aimed to identify a simple risk stratification for these patients based on perioperative factors.MethodsThe study was based on two randomized controlled trials (RCT) (NCT02715076, ChiCTR-IPR-17011099), including 839 patients undergoing elective radical resection of advanced digestive system cancer. The primary outcome was organ/space SSI within 30 days after surgery. Multivariable logistic regression model was used to identify risk factors. The risk of organ/space SSI stratified over those risk factors was compared using chi-square tests and the relative risk (RR) was estimated.ResultsAmong the 839 patients, 51 developed organ/space SSI (6.1%) within 30 days after surgery. According to the multivariable logistic regression model, 3 procedure types, including gastrectomy (OR=8.22, 95% CI: 2.71-24.87, P&lt;0.001), colorectal resection (OR=8.65, 95% CI: 3.13-23.85, P&lt;0.001) and pancreatoduodenectomy (OR=7.72, 95% CI: 2.95-20.21, P&lt;0.001), as well as anaesthesia time &gt; 4 h (OR=2.38, 95% CI: 1.08-5.27, P=0.032) and prolonged ICU stay (OR=4.10, 95% CI: 1.67-10.10, P=0.002), were risk factors for postoperative organ/space SSI. The number of risk factors was significantly associated with an increased risk of organ/space SSI (P&lt;0.001), which was 2.8% in patients with 0-1 risk factor (RR=0.20, 95% CI: 0.11-0.35), 13.0% in patients with 2 risk factors (RR=3.64, 95% CI: 2.14-6.20) and 35.7% in patients with 3 risk factors (RR=6.41, 95% CI: 3.01-13.65).ConclusionThis study is a preliminary exploratory and provides a simple risk stratification to identify the risk of postoperative organ/space SSI for patients with advanced digestive system cancer. Further research is needed to validate and generalize the results in a wider population.Clinical Trial RegistrationClinicalTrials.gov, identifier NCT02715076; Chinese Clinical Trial Registry [https://www.chictr.org.cn/enindex.aspx], identifier ChiCTR-IPR-17011099.

AbstractObjective:To investigate whether stratification of the risk of developing a surgical-site infection (SSI) is improved when a logistic regression model is used to weight the risk factors for each procedure category individually instead of the modified NNIS System risk index.Design and Setting:The German Nosocomial Infection Surveillance System, based on NNIS System methodology, has 273 acute care surgical departments participating voluntarily. Data on 9 procedure categories were included (214,271 operations).Methods:For each of the procedure categories, the significant risk factors from the available data (NNIS System risk index variables of ASA score, wound class, duration of operation, and endoscope use, as well as gender and age) were identified by multiple logistic regression analyses with stepwise variable selection. The area under the receiver operating characteristic (ROC) curve resulting from these analyses was used to evaluate the predictive power of logistic regression models.Results:For most procedures, at least two of the three variables contributing to the NNIS System risk index were shown to be independent risk factors (appendectomy, knee arthroscopy, cholecystectomy, colon surgery, herniorrhaphy, hip prosthesis, knee prosthesis, and vascular surgery). The predictive power of logistic regression models (including age and gender, when appropriate) was low (between 0.55 and 0.71) and for most procedures only slightly better than that of the NNIS System risk index.Conclusion:Without the inclusion of additional procedure-specific variables, logistic regression models do not improve the comparison of SSI rates from various hospitals.

AbstractSurgical site infection (SSI) following colorectal surgery is associated with worse postoperative outcomes, longer length of stay, and higher rates of readmission. SSI rates have been established as a surrogate metric for the overall quality of surgical care and are intricately tied to financial incentives and the public reputation of an institution. While risk factors and prevention mechanisms for SSI are well established, the rates of SSI remain high. This article discusses the clinical and economic impact of SSI and strategies for mitigating the risk of SSI through bundled prevention practices.
