Abstract
OBJECTIVE To compare the efficacy of several local antibiotic regimens in preventing surgical site infection (SSI) in clean surgical wounds. DATA SOURCES The authors searched CNKI (China National Knowledge Infrastructure), the VIP (VIP information resource integration service platform), Wanfang Data knowledge service platform (WANFANG), SinoMed, Cochrane Library, EMBASE, and PubMed. STUDY SELECTION A total of 20 randomized controlled trials published between January 1, 2000 and April 1, 2021 were included in this meta-analysis. DATA EXTRACTION Authors extracted the name of the first author, publication date, country, type of surgery, follow-up time, mean age of participants, sample size of each group, interventions, outcome indicators, and study type from each article. DATA SYNTHESIS The overall effectiveness of eight local managements in reducing the incidence of the SSI effect were compared through the SUCRA (surface under the cumulative ranking curve) probabilities. The results of a network meta-analysis demonstrated that gentamicin ointment (odds ratio [OR], 0.16; 95% CI, 0.04-0.60), mupirocin ointment (OR, 0.44; 95% CI, 0.21-0.94), and gentamicin soaking of the graft (OR, 0.63; 95% CI, 0.44-0.91) significantly reduced the incidence of SSI compared with control. Further, vancomycin soaking of the graft (86.7%) ranked first, followed by gentamicin ointment (81.1%), gentamicin irrigation (79.9%), mupirocin ointment (56.8%), triple antibiotic ointment (47.8%), gentamicin soaking of the graft (42.3%), and vancomycin powder (22.1%); ampicillin powder (17.8%) was the least effective drug. CONCLUSIONS The findings indicate that local antibiotics combined with conventional antibiotics in the wound before wound closure are effective in reducing the incidence of SSI in clean surgical wounds. Vancomycin inoculation of the graft exhibited the best effect.

Horgan S, Hegarty J, Drennan J, Keane D, Saab MM. The effect of interventions on the incidence of surgical site infections in acute care settings: A systematic review. J Tissue Viability 2024; 33:75-88. [PMID: 37977894 DOI: 10.1016/j.jtv.2023.11.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 09/22/2023] [Accepted: 11/08/2023] [Indexed: 11/19/2023]
Abstract
AIM Surgical site infections (SSIs) are common healthcare associated infections with serious consequences for patients and healthcare organisations. It is critical that healthcare professionals implement prevention strategies to reduce the incidence of such infections. Prevention strategies are key to reducing the incidence of SSIs. The aim of this systematic review is to describe the effect of interventions conducted in acute care settings on the incidence of SSIs (primary outcome), length of stay, intensive care unit admission, and mortality rate (secondary outcomes). MATERIALS AND METHODS This review is reported using the Preferred Reporting Items for Systematic review and Meta-Analysis checklist. A search was undertaken in Academic Search Complete, CINAHL, ERIC, MEDLINE, PsycARTICLES, PsycINFO and Web of Science for studies published between January 2017 and March 2022. Studies that focused on interventions within acute hospital settings in patients undergoing elective surgery with the aim of reducing the incidences of SSIs were included. Due to heterogeneity results were synthesised narratively. RESULTS In total, 23 studies were included. Findings show that interventions that are effective in reducing the incidences of SSIs have multiple components including care bundles, stakeholder engagement, targeted surveillance and education. Few studies were identified that evaluated the effect of SSI prevention interventions on length of stay and mortality, and none assessed intensive care admission rates. CONCLUSIONS The included interventions varied widely, which made it difficult to draw definitive conclusions regarding specific interventions that reduce SSI. Multicomponent interventions and care bundles showed promise in reducing the occurrence of SSIs. Further studies should focus on standardised evidence-based interventions and compliance using randomised controlled designs.

Abstract
AIM SSI is one of the most prevalent healthcare-associated infections and is associated with extended hospital stays, increased need for reoperation and higher hospital readmission rates. Implementing systematic SSI surveillance can reduce these adverse outcomes. Implementing a surveillance system into a hospital is a complex intervention requiring that staff involved in a patient's perioperative journey have the knowledge of SSI prevention, the data required for surveillance, an understanding of how data informs quality improvement initiatives and their role in surveillance. The aim of this study was to evaluate the impact of a complex intervention on the knowledge and attitudes of healthcare professionals towards surgical site infection (SSI), SSI prevention and surveillance in a university hospital setting. DESIGN The study used a quasi-experimental pre-test-post-test design. METHOD The impact of a complex intervention was evaluated by measuring healthcare professionals' (n = 74) knowledge of and attitudes towards SSI and surveillance. Normalisation process theory (NPT) guided the study and the development of the intervention. RESULTS There was a statistically significant increase in scores on the knowledge of SSI and prevention from pre-intervention to post-test. The knowledge of risk factors scores at post-test was significantly higher than that at pre-intervention. Overall attitudes to SSI prevention and surveillance were good both pre-intervention and post-test but there was a significant change in the attitude of participants. The findings reveal an overall positive impact of the complex intervention on the knowledge and attitude of healthcare professionals relating to SSI, SSI prevention and surveillance; however, the extent of the change varied across items measured.

Telemedicine for Surgical Site Infection Diagnosis in Rural Rwanda: Concordance and Accuracy of Image Reviews. World J Surg 2022; 46:2094-2101. [PMID: 35665833 DOI: 10.1007/s00268-022-06597-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/28/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND In rural Africa where access to medical personnel is limited, telemedicine can be leveraged to empower community health workers (CHWs) to support effective postpartum home-based care after cesarean section (c-section). As a first step toward telemedicine, we assessed the sensitivity, specificity, and interrater reliability of image-based diagnosis of surgical site infections (SSIs) among women delivering via c-section at a rural Rwandan Hospital. METHODS Women ≥18 years who underwent c-section from March to October 2017 at Kirehe District Hospital (KDH) were enrolled. On postoperative day 10 at KDH, participants underwent a physical examination by a general practitioner, who provided a diagnosis of SSI or no SSI. Trained CHWs photographed patients' incisions and the collected images were shown to six physicians, who upon review, assigned one of the following diagnoses to each image: definite SSI, suspected SSI, suspected no SSI, and definite no SSI, which were compared with the diagnoses based on physical exam. We report the sensitivity and specificity and assessed reviewer agreement using Gwet's AC1. RESULTS 569 images were included, with 61 women (10.7%) diagnosed with an SSI. Of the 3414 image-reviews, 49 (1.4%) could not be assigned diagnoses due to image quality. The median sensitivity and specificity were 0.83 and 0.69, respectively. The Gwet's AC1 estimate for binary classification was 0.46. CONCLUSIONS We demonstrate decent accuracy but only moderate consistency for photograph-based SSI diagnosis. Strategies to improve overall agreement include providing clinical information to accompany photographs, providing a baseline photograph for comparison, and implementing photograph-taking processes aimed at improving image quality.

Can clothing systems and human activities in operating rooms with mixing ventilation systems help achieve 10 CFU/m 3 level during orthopaedic surgeries? J Hosp Infect 2021; 120:110-116.

Abstract
The level of airborne microbial contamination in operating rooms (ORs) is an important indicator of indoor air quality and ensures a clean surgical environment. It is necessary to research how different factors affect the colony forming unit (CFU) level during surgery in a mixing ventilation (MV) operating room (OR) to fulfil an ultra-clean air requirement. The main objective of this study is to clarify the possibility of achieving the requirement for an ultraclean operating room (≤ 10 CFU/m3) with mixing ventilation from two factors of clothing and human activities. The experiment results verified that the average CFU/m3 of three of five mock-up surgeries was 8.5 which was below or equal to the ultra-clean requirement, while the other two mock-up surgeries did not meet the ultra-clean requirement. Surgical activities together with clothing level of surgical staff in ORs seem to be the most significant reason for the high CFU level during surgery. It is possible to achieve the ultraclean air requirement (≤ 10 CFU/m3) during a surgical process with proper clothing and low surgical activities in ORs. This study clarifies the effect of clothing and human activities on the CFU level in the surgical microenvironment in ORs and contributes to developing new code of products for the surgical team.

Abstract
Nosocomial infections or hospital-acquired infections are infections that potentially occur in the patients under medical care. These infections are often caused by multidrug-resistant pathogens acquired via improper antibiotic use, not following infection control and prevention procedures. The main objective of this study was to investigate the contribution of medical wards contamination to wound infection and antibiotics susceptibility patterns at Ruhengeri Referral Hospital, Musanze district, Rwanda. This was a cross-sectional study where a total of 61 samples including air sampling to evaluate the contamination by airborne bacteria, working surface, equipment, and patients' surgical wounds swabs were collected in intensive care unit (ICU), pediatrics, and surgery departments. Culture, Gram stain, and biochemical tests were performed for microbiological isolation and identification. Antibiotic susceptibility testing was performed using the Kirby-Bauer disc diffusion method. Statistical Package for Social Science (SPSS) version 22 was used for data analysis. Gram-negative bacteria were frequently from surgery, pediatric, and ICU with 68.8%, 63.9%, and 31.1%, respectively, while Gram-positive isolates were 37.7% in surgery, 32.9% in pediatric, and 18.0% in ICU. There was a statistically significant association with E. coli and swabbed materials and surgical wound sites (x 2 = 10.0253, P value = 0.018). All bacterial contaminants were sensitive to clindamycin and erythromycin. Pseudomonas aeruginosa, E. coli, and S. aureus were resistant to nitrofurantoin. Hospital environment could be a contributing factor to surgical wound site infections. Hospitals should apply preventive measures in the hospital environment surrounding wound surgery patients to prevent wound infections during hospital stay.

Abstract
BACKGROUND Surgical site infections (SSIs) are the second most common healthcare-associated infection. Active SSI surveillance can help inform preventative measures and assess the impact of these measures. AIM We aimed to describe the evolution in trends over 14 years of prospective active SSI surveillance and implementations of SSI prevention measures in a French Teaching Hospital. METHODS We monitored and included in the study all surgical procedures performed from 2003 to 2016 in eight surgical units. The semi-automated surveillance method consisted of weekly collection of SSI declaration forms (pre-filled with patient and procedure administrative data and microbiology laboratory data), filled-in by surgeons and then monitored by the infection control practitioners. FINDINGS A total of 181,746 procedures were included in our analysis and 3270 SSIs recorded (global SSI rate 1.8%). The SSI rate decreased significantly from 3.0% in 2003 to 1.1% in 2016. This decrease was mainly in superficial SSIs and high infectious risk procedures. Higher SSI rates were observed for procedures associated with the usual risk factors. During this 14-year period, several evolutions in surgical practices occurred that might have contributed to this decrease. CONCLUSIONS With an overall decrease in SSI rate throughout the surveillance, our results revealed the benefits of an active and comprehensive hospital SSI surveillance programme for understanding the SSI rate trends, analysing local risk factors and assessing the effectiveness of prevention strategies. These findings also highlighted the importance of the collaboration between surgeons and infection control practitioners.

Abstract
OBJECTIVE The incidence of surgical site infections may be underreported if the data are not routinely validated for accuracy. Our goal was to investigate the communicated SSI rate from a large network of Swiss hospitals compared with the results from on-site surveillance quality audits. DESIGN Retrospective cohort study. PATIENTS In total, 81,957 knee and hip prosthetic arthroplasties from 125 hospitals and 33,315 colorectal surgeries from 110 hospitals were included in the study. METHODS Hospitals had at least 2 external audits to assess the surveillance quality. The 50-point standardized score per audit summarizes quantitative and qualitative information from both structured interviews and a random selection of patient records. We calculated the mean National Healthcare Safety Network (NHSN) risk index adjusted infection rates in both surgery groups. RESULTS The median NHSN adjusted infection rate per hospital was 1.0% (interquartile range [IQR], 0.6%-1.5%) with median audit score of 37 (IQR, 33-42) for knee and hip arthroplasty, and 12.7% (IQR, 9.0%-16.6%), with median audit score 38 (IQR, 35-42) for colorectal surgeries. We observed a wide range of SSI rates and surveillance quality, with discernible clustering for public and private hospitals, and both lower infection rates and audit scores for private hospitals. Infection rates increased with audit scores for knee and hip arthroplasty (P value for the slope = .002), and this was also the case for planned (P = .002), and unplanned (P = .02) colorectal surgeries. CONCLUSIONS Surveillance systems without routine evaluation of validity may underestimate the true incidence of SSIs. Audit quality should be taken into account when interpreting SSI rates, perhaps by adjusting infection rates for those hospitals with lower audit scores.

Abstract
BACKGROUND AND OBJECTIVE Chlorhexidine (CH) and povidone-iodine (PI) are the most commonly used preoperative skin antiseptics at present. However, the prevention of the surgical site infection (SSI) and the incidence of skin adverse events do not reach a consistent statement and conclusion. This meta-analysis aimed to evaluate the efficacy of chlorhexidine and povidone-iodine in the prevention of postoperative surgical site infection and the incidence of corresponding skin adverse events. METHOD Substantial studies related to "skin antiseptic" and "surgical site infection" were consulted on PUBMED, Web of Science, EMBASE, and CNKI. The primary outcome was the incidence of postoperative SSI. The secondary outcome was associated with skin adverse events. All data were analyzed with Revman 5.3 software. RESULTS A total of 30 studies were included, including 29,006 participants. This study revealed that chlorhexidine was superior to povidone-iodine in the prevention of postoperative SSI (risk ratio [RR], 0.65; 95% confidence interval [CI], 0.55-0.77; p < 0.00001, I2 = 57%). Further subgroup analysis showed that chlorhexidine was superior to povidone-iodine in the prevention of postoperative SSI in clean surgery (risk ratio [RR], 0.81; 95% confidence interval [CI], 0.67-0.98; p = 0.03), I2 = 28%) and clean-contaminated surgery (risk ratio [RR], 0.58; 95% confidence interval [CI], 0.47-0.73; p < 0.00001, I2 = 43%). However, there was no statistically significant difference in the incidence of skin adverse events between CH and PI groups. CONCLUSION Chlorhexidine was superior to povidone-iodine in preventing postoperative SSI, especially for the clean-contaminated surgery. However, there was no statistically significant difference in the incidence of skin adverse events between CH and PI groups.

Abstract
The objective of this study was to identify the occurrence of complicated surgical wounds (CSWs) and to analyze the associated factors in hospitalized patients at an oncology institution. This was an epidemiological, observational, cross-sectional, descriptive, and correlational study conducted in the intensive care and hospitalization units forming part of a large cancer hospital. Sociodemographic and clinical data were collected from medical records and physical examinations of the skin. Associations between the dependent variable (presence of CSWs) and the independent variables were obtained by chi-square tests and odds ratio (OR) calculations with a 95% confidence interval. Logistic regression (LASSO) was used to verify the possible predictors of the outcome. The sample consisted of 341 patients, specifically individuals who are White (46.9%), married (53.4%), and men (58.1%) with an average age of 59.2 years. Complicated surgical wounds were present in 3.2% of patients, and the most frequent types of complications were dehiscence (40%), infection (26.7%), and fistula (20%) present in the abdominal (40%), cephalic (26.7%), and cervical (13.3%) regions. Senile purpura, diaper use, and infection were the clinical variables associated with the occurrence of CSWs (p = .044, p = .001, and p < .001, respectively). Based on the logistic regression, the presence of infection (p < .001; OR = 90.8; 95% CI [18.42, 538.79]) persisted as a predictor of the occurrence of CSWs. From these observations, recommendations regarding best practices for the prevention of CSWs are made, specifically for patients with cancer.

Abstract
Background The World Health Organization have designed the fifth of their '5 moments' for hand hygiene to account for microbial transfer from patients to equipment in a narrow area around that patient, known as the patient zone. The study was prompted by emerging local confusion about application of the patient zone in the operating room (OR). Aim/Objectives In two phases, we aimed to create a '5 moments' style poster displaying an OR patient zone: phase 1, quantify equipment, in direct contact with the patient and, touched by non-scrubbed staff immediately after touching the patient; and phase 2, categorise equipment identified in phase 1 into patient zone and healthcare zone. An objective is to produce a '5 moments' poster for the OR. Methods The first phase used non-participant direct overt observation. In phase 2, phase 1 data were collaboratively assigned to patient zone or healthcare zone. Photography and graphic design were used to produce the OR '5 moments' poster. Results In 11 full-length surgeries, 20 pieces of equipment were in direct contact with the patient and 57 pieces of equipment were touched. In phase 2, a '5 moments' poster showing an OR patient zone was designed. Discussion Content of the patient zone was identified and displayed in a novel resource. Having shared understanding of the patient zone has potential to sustain hand hygiene compliance and equipment cleaning in the OR. Conclusion Limitations in methods were balanced by collaboration with frontline staff. The study has been used as a teaching tool in the OR and similar settings.

Abstract
BACKGROUND Povidone iodine (PVI) is a widely used antiseptic solution among surgeons. A meta-analysis based on randomized controlled trials (RCTs) was conducted to establish whether application of PVI before wound closure could reduce surgical site infection (SSI) rates. METHODS Systematic review of MEDLINE/PubMed, Scopus, CINAHL, and Web of Science databases from inception to September 2017, with no language restrictions. Only RCTs were retrieved. The primary outcome was the SSI rate. Meta-analysis was complemented with trial sequential analysis (TSA). RESULTS A total of 7601 patients collected from 16 RCTs were analyzed. A reduction in overall SSI rate was found (RR 0.64, 95% CI 0.48-0.85, P = 0.002, I2 = 65%), which was attributed to patients undergoing elective operations (n = 2358) and mixed elective/urgent operations (n = 2019). When RCTs of uncertain quality (n = 9) were excluded, the use of PVI before wound closure (n = 4322 patients) was not associated with a significant reduction of SSI (RR 0.81, 95% CI 0.55-1.20, P = 0.29, I2 = 51%) and was only significant in clean wounds (RR 0.25, 95% CI 0.09-0.70, P = 0.008, I2 = 0%). For the primary outcome, the TSA calculation using a relative risk reduction of 19% and an 11% proportion of control event rate (CER) with 51% of I2, the accrued information size (n = 4322) was 32.8% of the estimated optimal information size (n = 13,148). CONCLUSIONS There is no conclusive evidence for a strong recommendation of topical PVI before wound closure to prevent SSI.

Prevalence and predictors of surgical-site infection after caesarean section at a rural district hospital in Rwanda. Br J Surg 2019; 106:e121-e128. [PMID: 30620071 PMCID: PMC7938824 DOI: 10.1002/bjs.11060] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2018] [Revised: 09/30/2018] [Accepted: 10/30/2018] [Indexed: 11/26/2022]
Abstract
Background There are few prospective studies of outcomes following surgery in rural district hospitals in sub-Saharan Africa. This study aimed to estimate the prevalence and predictors of surgical-site infection (SSI) following caesarean section at Kirehe District Hospital in rural Rwanda. Methods Adult women who underwent caesarean section between March and October 2017 were given a voucher to return to the hospital on postoperative day (POD) 10 (±3 days). At the visit, a physician evaluated the patient for an SSI. A multivariable logistic regression model was used to identify risk factors for SSI, built using backward stepwise selection. Results Of 729 women who had a caesarean section, 620 were eligible for follow-up, of whom 550 (88·7 per cent) returned for assessment. The prevalence of SSI on POD 10 was 10·9 per cent (60 women). In the multivariable analysis, the following factors were significantly associated with SSI: bodyweight more than 75 kg (odds ratio (OR) 5·98, 1·56 to 22·96; P = 0·009); spending more than €1·1 on travel to the health centre (OR 2·42, 1·31 to 4·49; P = 0·005); being a housewife compared with a farmer (OR 2·93, 1·08 to 7·97; P = 0·035); and skin preparation with a single antiseptic compared with a combination of two antiseptics (OR 4·42, 1·05 to 18·57; P = 0·043). Receiving either preoperative or postoperative antibiotics was not associated with SSI. Conclusion The prevalence of SSI after caesarean section is consistent with rates reported at tertiary facilities in sub-Saharan Africa. Combining antiseptic solutions for skin preparation could reduce the risk of SSI.

Use of Topical Antibiotics before Primary Incision Closure to Prevent Surgical Site Infection: A Meta-Analysis. Surg Infect (Larchmt) 2019; 20:261-270. [PMID: 30839242 DOI: 10.1089/sur.2018.279] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/07/2023] Open
Abstract
Background: Surgical site infections (SSIs) remains a concern for surgeons because of the negative impact on outcomes and health care costs. Our purpose was to assess whether topical antibiotics before primary incision closure reduced the rate of SSIs. Methods: Systematic review of MEDLINE/PubMed, Scopus, CINAHL, and Web of Science databases from inception to January 2017. Only randomized controlled trials (RCTs) were retrieved. The primary outcome was the SSI rate. Meta-analysis was complemented with trial sequential analysis (TSA). Results: Thirty-five RCTs (10,870 patients) were included. Only β-lactams and aminoglycosides were used. A substantial reduction of the incidence of SSIs with the application of antibiotic agents before incision closure (risk ratio [RR] 0.49, 95% confidence interval [CI] 0.37-0.64) was found, which remained in the analysis of 12 RCTs after removal of studies of uncertain quality. The use of β-lactams was effective to reduce SSI in elective surgery only (RR 0.33, 95% CI 0.13-0.85). In clean-contaminated fields and as an irrigation solution, β-lactams did not reduce the risk of SSI. Aminoglycosides were not effective (RR 0.74, 95% CI 0.49-1.10). After TSA, the evidence accumulated was far below the optimal information size. The heterogeneity of studies was high and methodological quality of most RCTs included in the meta-analysis was uncertain. Conclusions: Results of this meta-analysis show the data present in the literature are not sufficiently robust and, therefore, the use of topical β-lactams or aminoglycosides before incision closure to reduce SSI cannot be recommended or excluded.

Maximizing Interpretability and Cost-Effectiveness of Surgical Site Infection (SSI) Predictive Models Using Feature-Specific Regularized Logistic Regression on Preoperative Temporal Data. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2019; 2019:2059851. [PMID: 30915154 PMCID: PMC6399553 DOI: 10.1155/2019/2059851] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2018] [Accepted: 01/17/2019] [Indexed: 12/14/2022]
Abstract
This study describes a novel approach to solve the surgical site infection (SSI) classification problem. Feature engineering has traditionally been one of the most important steps in solving complex classification problems, especially in cases with temporal data. The described novel approach is based on abstraction of temporal data recorded in three temporal windows. Maximum likelihood L1-norm (lasso) regularization was used in penalized logistic regression to predict the onset of surgical site infection occurrence based on available patient blood testing results up to the day of surgery. Prior knowledge of predictors (blood tests) was integrated in the modelling by introduction of penalty factors depending on blood test prices and an early stopping parameter limiting the maximum number of selected features used in predictive modelling. Finally, solutions resulting in higher interpretability and cost-effectiveness were demonstrated. Using repeated holdout cross-validation, the baseline C-reactive protein (CRP) classifier achieved a mean AUC of 0.801, whereas our best full lasso model achieved a mean AUC of 0.956. Best model testing results were achieved for full lasso model with maximum number of features limited at 20 features with an AUC of 0.967. Presented models showed the potential to not only support domain experts in their decision making but could also prove invaluable for improvement in prediction of SSI occurrence, which may even help setting new guidelines in the field of preoperative SSI prevention and surveillance.

Abstract
Background: Hospital infections have affected millions of people around the world and are considered as one of the most important issues related to patient safety. Therefore, this study was conducted to estimate the extra costs caused by hospital-acquired infections in
hospitals.
Methods: This retrospective cohort study was conducted in Tehran province, Iran, in 2017. Medical records of 235 patients hospitalized in one of Tehran hospitals were reviewed for the study. They were divided into case (90 patients) and control (145 patients) groups. Data were analyzed using SPSS and STATA software.
Results: Results revealed no significant relationship between age and gender with the incidence of nosocomial infection (p>0.05). However, the chance of nosocomial infection is most affected by length of hospital stay and costs paid by patients. Moreover, nosocomial infection increases the length of hospital stay up to 25 days. Our results revealed that the mean±SD hospital stay of infected and non-infected patients were 15.8±17.2 and 40.8±19.1 days, respectively. Furthermore, the total cost of patients without any hospital infection was 2451±3098 USD (83 674 480±105 765 500 Rials). On the other hand, the cost for infected patients was 3264±6078 USD (207 497 500±111 430 700 Rials).
Conclusion: Hospital-acquired infections can impose great costs on both patients and the health system. The results of this study indicated the importance of taking specific measures for infection control in hospitals.

Comparative clinical effectiveness of preoperative skin antiseptic preparations of chlorhexidine gluconate and povidone iodine for preventing surgical site infections in dogs. Int J Vet Sci Med 2018; 6:113-116. [PMID: 30255087 PMCID: PMC6149254 DOI: 10.1016/j.ijvsm.2018.03.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2017] [Revised: 03/09/2018] [Accepted: 03/14/2018] [Indexed: 01/10/2023] Open
Abstract
Contamination of surgical sites often resulting from inadequate surgical site preparation and poor asepsis is a common cause of surgical site infection (SSI) and postoperative complications. Standard practice ensuring preoperative skin disinfection helps to prevent the incidence of SSI. The choice of antiseptic therefore poses a serious counterbalance for the surgeon. This study was carried out to determine whether skin asepsis immediately prior to surgical site incision will reduce skin microbial burden that may potentiate the incidence of SSI and to compare the clinical effectiveness of chlorhexidine gluconate B.P 0.3%W/V, Cetrimide B.P 3.05 W/V (CG + Cetrimide) against povidone iodine 10% (PI) in pre-surgical skin preparation and asepsis in dogs. A total of 15 dogs were used for the study. Both side of each dog was used for the study, right side for CG + Certrimide and left side for PI; (n = 30). Aseptic agents’ chlorhexidine gluconate 0.3% and Cetrimide 3.0% and povidine iodine 10% were used as pre surgical scrub solutions prior to surgery. Swab samples were evaluated before scrubbing, 0, 30, 60 and 90 min after scrubbing. Percent reductions of bacterial colony forming units were determined for all site scrub techniques. Mixed-design ANOVA results revealed significant difference (P < 0.05) within groups and no significant difference (P > 0.05) in the disinfectant effects between groups treated with CG + Cetrimide and povidone iodine respectively across the various time periods. Changes in the mean bacteria count were observed to be equivalent using CG + Cetrimide and povidone iodine. It was concluded that there was no significant difference between CG + Cetrimide and PI in preoperative surgical skin preparations.

Abstract
Background The role of hospital water systems in the development of Pseudomonas aeruginosa (P. aeruginosa) surgical site infections (SSIs) in low-income countries is barely studied. This study characterized P. aeruginosa isolates from patients and water in order to establish possible epidemiological links. Methods Between December 2014 and September 2015, rectal and wound swabs, and water samples were collected in the frame of active surveillance for SSIs in the two Tanzanian hospitals. Typing of P. aeruginosa was done by multi-locus sequence typing. Results Of 930 enrolled patients, 536 were followed up, of whom 78 (14.6%, 95% CI; 11.6–17.5) developed SSIs. P. aeruginosa was found in eight (14%) of 57 investigated wounds. Of the 43 water sampling points, 29 were positive for P. aeruginosa. However, epidemiological links to wound infections were not confirmed. The P. aeruginosa carriage rate on admission was 0.9% (8/930). Of the 363 patients re-screened upon discharge, four (1.1%) possibly acquired P. aeruginosa during hospitalization. Wound infections of the three of the eight P. aeruginosa SSIs were caused by a strain of the same sequence type (ST) as the one from intestinal carriage. Isolates from patients were more resistant to antibiotics than water isolates. Conclusions The P. aeruginosa SSI rate was low. There was no evidence for transmission from tap water. Not all P. aeruginosa SSI were proven to be endogenous, pointing to other routes of transmission.

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.
