OBJECTIVESurgical site infection (SSI) following spine surgery causes major morbidity and greatly impedes functional recovery. In the modern era of advanced operative techniques and improved perioperative care, SSI remains a problematic complication that may be reduced with institutional practices. The objectives of this study were to 1) characterize the SSI rate and microbial etiology following spine surgery for various thoracolumbar diseases, and 2) identify risk factors that were associated with SSI despite current perioperative management.METHODSAll patients treated with thoracic or lumbar spine operations on the neurosurgery service at the University of California, San Francisco from April 2012 to April 2016 were formally reviewed for SSI using the National Healthcare Safety Network (NHSN) guidelines. Preoperative risk variables included age, sex, BMI, smoking, diabetes mellitus (DM), coronary artery disease (CAD), ambulatory status, history of malignancy, use of preoperative chlorhexidine gluconate (CHG) showers, and the American Society of Anesthesiologists (ASA) classification. Operative variables included surgical pathology, resident involvement, spine level and surgical technique, instrumentation, antibiotic and steroid use, estimated blood loss (EBL), and operative time. Multivariable logistic regression was used to evaluate predictors for SSI. Odds ratios and 95% confidence intervals were reported.RESULTSIn total, 2252 consecutive patients underwent thoracolumbar spine surgery. The mean patient age was 58.6 ± 13.8 years and 49.6% were male. The mean hospital length of stay was 6.6 ± 7.4 days. Sixty percent of patients had degenerative conditions, and 51.9% underwent fusions. Sixty percent of patients utilized presurgery CHG showers. The mean operative duration was 3.7 ± 2 hours, and the mean EBL was 467 ± 829 ml. Compared to nonfusion patients, fusion patients were older (mean 60.1 ± 12.7 vs 57.1 ± 14.7 years, p < 0.001), were more likely to have an ASA classification > II (48.0% vs 36.0%, p < 0.001), and experienced longer operative times (252.3 ± 120.9 minutes vs 191.1 ± 110.2 minutes, p < 0.001). Eleven patients had deep SSI (0.49%), and the most common causative organisms were methicillin-sensitive Staphylococcus aureus and methicillin-resistant S. aureus. Patients with CAD (p = 0.003) or DM (p = 0.050), and those who were male (p = 0.006), were predictors of increased odds of SSI, and presurgery CHG showers (p = 0.001) were associated with decreased odds of SSI.CONCLUSIONSThis institutional experience over a 4-year period revealed that the overall rate of SSI by the NHSN criteria was low at 0.49% following thoracolumbar surgery. This was attributable to the implementation of presurgery optimization, and intraoperative and postoperative measures to prevent SSI across the authors’ institution. Despite prevention measures, having a history of CAD or DM, and being male, were risk factors associated with increased SSI, and presurgery CHG shower utilization decreased SSI risk in patients.

Object The purpose of this study was to identify risk factors for surgical site infection after spine surgery, noting the amount of saline used for intraoperative irrigation to minimize wound contamination. Methods The authors studied 223 consecutive spine operations from January 2006 through December 2006 at our institute. For a case to meet inclusion criteria as a site infection, it needed to require surgical incision and drainage and show positive intraoperative cultures. Preoperative and intraoperative data regarding each patient were collected. Patient characteristics recorded included age, sex, and body mass index (BMI). Preoperative risk factors included preoperative hospital stay, history of smoking, presence of diabetes, and an operation for a traumatized spine. Intraoperative factors that might have been risk factors for infection were collected and analyzed; these included type of procedure, estimated blood loss, duration of operation, and mean amount of saline used for irrigation per hour. Data were subjected to univariate and multivariate logistic regression analyses. Results The incidence of surgical site infection in this population was 6.3%. According to the univariate analysis, there was a significant difference in the mean duration of operation and intraoperative blood loss, but not in patient age, BMI, or preoperative hospital stay. The mean amount of saline used for irrigation in the infected group was less than in the noninfected group, but was not significantly different. In the multivariate analysis, sex, advanced age (> 60 years), smoking history, and obesity (BMI > 25 kg/m2) did not show significant differences. In the analysis of patient characteristics, only diabetes (patients receiving any medications or insulin therapy at the time of surgery) was independently associated with an increased risk of surgical site infection (OR 4.88). In the comparison of trauma and elective surgery, trauma showed a significant association with surgical site infection (OR 9.42). In the analysis of surgical factors, a sufficient amount of saline for irrigation (mean > 2000 ml/hour) showed a strong association with the prevention of surgical site infection (OR 0.08), but prolonged operation time (> 3 hours), high blood loss (> 300 g), and instrumentation were not associated with surgical site infection. Conclusions Diabetes, trauma, and insufficient intraoperative irrigation of the surgical wound were independent and direct risk factors for surgical site infection following spine surgery. To prevent surgical site infection in spine surgery, it is important to control the perioperative serum glucose levels in patients with diabetes, avoid any delay of surgery in patients with trauma, and decrease intraoperative contamination by irrigating > 2000 ml/hour of saline in all patients.

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.

Abstract Background Surgical site infection (SSI) is a common postoperative complication. We aimed to analyze the potential risk factors of SSI in patients with endometrial carcinoma. Methods Patients with endometrial carcinoma who underwent surgery treatment in our hospital from Sept 1, 2018 to August 31, 2020 were included. We retrospectively compared the characteristics of SSI and no SSI patients, and logistic regression analyses were performed to identify the risk factors of SSI in patients with endometrial carcinoma. Results A total of 318 postoperative patients with endometrial carcinoma were included. The incidence of SSI in patients with endometrial carcinoma was 14.47 %. There were significant differences on the FIGO stage, type of surgery, durations of drainage, postoperative serum albumin and postoperative blood sugar (all p < 0.05), and no significant differences on the age, BMI, hypertension, diabetes, hyperlipidemia, estimated blood loss, length of hospital stay were found (all p > 0.05). FIGO stage IV (HR3.405, 95 %CI 2.132–5.625), open surgery (HR2.692, 95 %CI 1.178–3.454), durations of drainage ≥ 7 d (HR2.414,95 %CI 1.125–2.392), postoperative serum albumin < 30 g/L (HR1.912,95 %CI 1.263–2.903), postoperative blood sugar ≥ 10 mmol/L (HR1.774,95 %CI 1.102–2.534) were the independent risk factors of SSI in patients with endometrial carcinoma (all p <  0.05). Conclusions Measures including reasonable control of serum albumin and blood glucose levels, minimally invasive surgery as much as possible, timely assessment of drainage and early removal of the tube may be beneficial to reduce the postoperative SSI in in patients with endometrial carcinoma.

Background: Surgical site infection (SSI) is a common complication following caesarean section (C-section) and mainly responsible for increased maternal morbidity and higher treatment costs. This study will determine the incidence and risk factors of surgical site infections following caesarean section in Dhaka Medical College Hospital (DMCH). Materials and Methods: This is a retrospective observational study which was conducted among patients having post caesarean surgical site infections attending post-natal outdoor clinic of DMCH from January, 2019 to December, 2019. Data were collected in structured questionnaire. Culturebased microbiological methods were used to identify causal agents in postoperative wounds. Results: Overall SSI rate following caesarian section was 4.44%.Patient related risk factors were inadequate antenatal check-up, emergency procedures, malnutrition (22.44%), anaemia (21.46%) associated comorbidity (59.46%), history of rupture membrane >12 hours (40.98%) and had history of prolonged labour pain >12 hours (16.10%).Surgery related risk factors were repeated per vaginal examinations by untrained birth attendant (21.95%) & duration of surgery>1 hour (62.93%). The most common organisms responsible for SSI were Staphylococcus aureus 44(21.46%) and Escherichia coli 31(15.12%). The most sensitive antibiotics were aminoglycosides, cephalosporin & cloxacillin. Conclusion: Most of the risk factors for surgical site infection following caesarean section identified in this study can be modified through intervention. However the microorganisms detected from our patient showed a high degree of resistance for commonly prescribed antimicrobials in our set-up.

OBJECTIVENutritional deficiency negatively affects outcomes in many health conditions. In spine surgery, evidence linking preoperative nutritional deficiency to postoperative surgical site infection (SSI) has been limited to small retrospective studies. Authors of the current study analyzed a large consecutive cohort of patients who had undergone elective spine surgery to determine the relationship between a serum biomarker of nutritional status (preoperative prealbumin levels) and SSI.METHODSThe authors conducted a retrospective review of the electronic medical charts of patients who had undergone posterior spinal surgeries and whose preoperative prealbumin level was available. Additional data pertinent to the risk of SSI were also collected. Patients who developed a postoperative SSI were identified, and risk factors for postoperative SSI were analyzed. Nutritional deficiency was defined as a preoperative serum prealbumin level ≤ 20 mg/dl.RESULTSAmong a consecutive series of 387 patients who met the study criteria for inclusion, the infection rate for those with preoperative prealbumin ≤ 20 mg/dl was 17.8% (13/73), versus 4.8% (15/314) for those with preoperative prealbumin > 20 mg/dl. On univariate and multivariate analysis a low preoperative prealbumin level was a risk factor for postoperative SSI with a crude OR of 4.29 (p < 0.01) and an adjusted OR of 3.28 (p = 0.02). In addition, several previously known risk factors for infection, including diabetes, spinal fusion, and number of operative levels, were significant for the development of an SSI.CONCLUSIONSIn this consecutive series, preoperative prealbumin levels, a serum biomarker of nutritional status, correlated with the risk of SSI in elective spine surgery. Prehabilitation before spine surgery, including strategies to improve nutritional status in patients with nutritional deficiencies, may increase value and improve spine care.

Study Design: Retrospective literature review of spine surgical site infection (SSI). Objective: To perform a review of SSI risk factors and more specifically, categorize them into patient and surgical factors. Methods: A review of published literature on SSI risk factors in adult spine surgery was performed. We included studies that reported risk factors for SSI in adult spinal surgery. Excluded are pediatric patient populations, systematic reviews, and meta-analyses. Overall, we identified 72 cohort studies, 1 controlled-cohort study, 1 matched-cohort study, 1 matched-paired cohort study, 12 case-controlled studies (CCS), 6 case series, and 1 cross-sectional study. Results: Patient-associated risk factors—diabetes mellitus, obesity (body mass index >35 kg/m2), subcutaneous fat thickness, multiple medical comorbidities, current smoker, and malnutrition were associated with SSI. Surgical associated factors—preoperative radiation/postoperative blood transfusion, combined anterior/posterior approach, surgical invasiveness, or levels of instrumentation were associated with increased SSI. There is mixed evidence of age, duration of surgery, surgical team, intraoperative blood loss, dural tear, and urinary tract infection/urinary catheter in association with SSI. Conclusion: SSIs are associated with many risk factors that can be patient or surgically related. Our review was able to identify important modifiable and nonmodifiable risk factors that can be essential in surgical planning and discussion with patients.
