<p class="abstract"><strong>Background:</strong> Surgical-site infection accounts for approximately 10% of all hospital-acquired infections, which are estimated to double the cost of care and result in an additional mean of 6.5 days of hospital stay. We did prospective study of surgical site infection of orthopaedic implant surgeries.</p><p class="abstract"><strong>Methods:</strong> The aim of the study is to assess the clinical and microbiological outcome of 125 patients who had open reduction and internal fixation with implants and prosthesis at Southern Railway Hospital from January 2006 to January 2007, and its strength of association with major risk factors using univariate analysis. In our study, Patients were allocated in to three groups as NINS risk index group 0, 1 and 2 with risk factors as duration of surgery &gt;2 hours and ASA class ≥3. Post-operative wound infection was diagnosed based on the criteria of Center of Disease Control and assessed for the period of 6 weeks using National Nosocomial Infections Surveillance Risk Index.<strong></strong></p><p class="abstract"><strong>Results:</strong> There were 87 male and 38 females in the study. From 125 Patients, 13 patients had post-operative superficial surgical site infection and presented within 21 days of operation. The infection rate was 10.4%. Two Patients developed deep infection after 6 weeks of study. All the cases with superficial infection were followed at regular intervals, 11 cases resolved with regular dressing and antibiotics but 2 cases continued to discharge sinus up to 3 months.</p><p><strong>Conclusions:</strong> The study showed that the risk of infection rate increased significantly with ASA score, duration of surgery, obesity and NINS risk index. There was no significant association of infection rate with age, diabetes and smoking. </p>

Objectives.To assess the appropriateness of using the indices developed by the Study on the Efficacy of Nosocomial Infection Control (SENIC) and the National Nosocomial Infections Surveillance (NNIS) project to determine risk factors for surgical site infection (SSI) in children and, if not appropriate, to explore the factors related to SSI in children so these factors could be used in a risk index for pediatric patients.Design.Cohort study during more than 4 years.Setting.La Paz University Hospital, a national reference center that serves Health Area 5 of Madrid, Spain, which has approximately 500,000 inhabitants.Patients.Convenience sample consisting of the 3,646 children admitted for surgery who had a postsurgical stay of more than 2 days.Results.A model with 8 predictive factors (degree of surgical contamination; duration of surgery; type of surgery; use of a peripheral venous catheter, central venous catheter, or urinary catheter; number of diagnoses; and SSI exposition time) was created. Its relation to the SSI rate was better than that of the SENIC or NNIS indices. Its sensitivity, specificity, and area under the receiver–operating characteristic curve were higher than that of the SENIC index.Conclusions.The model that we created seems to be more adequate for predicting SSI and evaluating pediatric patients' intrinsic risk than the SENIC and NNIS indices.

ABSTRACT Objective: to estimate the incidence of surgical site infection in general surgeries at a large Brazilian hospital while identifying risk factors and prevalent microorganisms. Method: non-concurrent cohort study with 16,882 information of patients undergoing general surgery from 2008 to 2011. Data were analyzed by descriptive, bivariate and multivariate analysis. Results: the incidence of surgical site infection was 3.4%. The risk factors associated with surgical site infection were: length of preoperative hospital stay more than 24 hours; duration of surgery in hours; wound class clean-contaminated, contaminated and dirty/infected; and ASA index classified into ASA II, III and IV/V. Staphyloccocus aureus and Escherichia coli were identified. Conclusion: the incidence was lower than that found in the national studies on general surgeries. These risk factors corroborate those presented by the National Nosocomial Infection Surveillance System Risk Index, by the addition of the length of preoperative hospital stay. The identification of the actual incidence of surgical site infection in general surgeries and associated risk factors may support the actions of the health team in order to minimize the complications caused by surgical site infection.

Background: Assessment of surgical site infection is an important factor to determine the functioning of the health care system. Objectives of this study was to estimate the incidence of surgical site infection among caesarean section cases and to determine the risk factors associated with surgical site infection and comparison with patients having healthy wounds.Methods: One thousand pregnant women who underwent caesarean section were divided into two groups: Group 1 (cases): Those who had SSI within 30 days of caesarean section and Group 2 (controls): Those who didn’t have SSI.Results: Mean age of group I was 25.35±4.40 and 21.12±3.60 years in group II (p >0.05). Mean gestational age of group I cases was 38.07±1.88 weeks and in group II, it was 38.17±2.06 weeks (p >0.05). A total of 37 (82.5%) women in group I and 931 (96.98%) women in group II underwent emergency caesarean section (p <0.05). In group I, mean duration of surgery was 1.0±0.13 hours and 1.02±0.21 hours in group II (p <0.05). Maximum number of patients i.e. 22 (55%) had wound discharge between 4-7 days followed by 11 (27.5%) between 8-10 days. Mean wound discharge was 7.32±3.45 days in group I. Majority of women, i.e. 27 (67%) found to be sterile in the present study followed by 7 (17.5%) women were found to have staphylococcus aureus.      Mean duration of resuturing was 17.42±6.98 days.  Mean baby weight in group I was 2.72±0.53 kg and in group II it was 2.95±0.53 kg (p <0.001).Conclusions: Risk of developing SSI after caesarean section is multi-factorial and found to be influenced by emergency surgery, PROM, pre-operative anaemia, multiple vaginal examinations, interrupted skin suturing, raised BMI, nulliparity, emergency caesarean, duration of surgery.

Abstract Purposes Surgical site infection (SSI) after colorectal surgery is a frequent complication associated with the increase in morbidity, medical expenses, and mortality. To date, there is no nationwide large-scale database of SSI after colorectal surgery in China. The aim of this study was to determine the incidence of SSI after colorectal surgery in China and to further evaluate the related risk factors. Methods Two multicenter, prospective, cross-sectional studies covering 55 hospitals in China and enrolling adult patients undergoing colorectal surgery were conducted from May 1 to June 30 of 2018 and the same time of 2019. The demographic and perioperative characteristics were collected, and the main outcome was SSI within postoperative 30 days. Multivariable logistic regressions were conducted to predict risk factors of SSI after colorectal surgery. Results In total, 1046 patients were enrolled and SSI occurred in 74 patients (7.1%). In the multivariate analysis with adjustments, significant factors associated with SSI were the prior diagnosis of hypertension (OR, 1.903; 95% confidence interval [CI], 1.088–3.327, P = 0.025), national nosocomial infection surveillance risk index score of 2 or 3 (OR, 3.840; 95% CI, 1.926–7.658, P < 0.001), laparoscopic or robotic surgery (OR, 0.363; 95% CI, 0.200–0.659, P < 0.001), and adhesive incise drapes (OR, 0.400; 95% CI, 0.187–0.855, P = 0.018). In addition, SSI group had remarkably increased length of postoperative stays (median, 15.0 d versus 9.0d, P < 0.001), medical expenses (median, 74,620 yuan versus 57,827 yuan, P < 0.001), and the mortality (4.1% versus 0.3%, P = 0.006), compared with those of non-SSI group. Conclusion This study provides the newest data of SSI after colorectal surgery in China and finds some predictors of SSI. The data presented in our study can be a tool to develop optimal preventive measures and improve surgical quality in China.

Objective.To identify risk factors associated with surgical site infection (SSI) after pediatric posterior spinal fusion procedure by examining characteristics related to the patient, the surgical procedure, and tissue hypoxia.Design.Retrospective case-control study nested in a hospital cohort study.Setting.A 475-bed, tertiary care children's hospital.Methods.All patients who underwent a spinal fusion procedure during the period from January 1995 through December 2006 were included. SSI cases were identified by means of prospective surveillance using National Nosocomial Infection Surveillance system definitions. Forty-four case patients who underwent a posterior spinal fusion procedure and developed an SSI were identified and evaluated. Each case patient was matched (on the basis of date of surgery, ± 3 months) to 3 control patients who underwent a posterior spinal fusion procedure but did not develop an SSI. Risk factors for SSI were evaluated by univariate analysis and multivariable conditional logistic regression. Odds ratios (ORs), with 95% confidence intervals (CIs) andPvalues, were calculated.Results.From 1995 to 2006, the mean annual rate of SSI after posterior spinal fusion procedure was 4.4% (range, 1.1%—6.7%). Significant risk factors associated with SSI in the univariate analysis included the following: a body mass index (BMI) greater than the 95th percentile (OR, 3.5 [95% CI, 1.5–8.3]); antibiotic prophylaxis with clindamycin, compared with other antibiotics (OR, 3.5 [95% CI, 1.2 10.0]); inappropriately low dose of antibiotic (OR, 2.6 [95% CI, 1.0–6.6]); and a longer duration of hypothermia (ie, a core body temperature of less than 35.5°C) during surgery (OR, 0.4 [95% CI, 0.2–0.9]). An American Society of Anesthesiologists (ASA) score of greater than 2, obesity (ie, a BMI greater than the 95th percentile), antibiotic prophylaxis with clindamycin, and hypothermia were statistically significant in the multivariable model.Conclusion.An ASA score greater than 2, obesity, and antibiotic prophylaxis with clindamycin were independent risk factors for SSI. Hypothermia during surgery appears to provide protection against SSI in this patient population.
