Role of single or double ringed circumferential wound protectors in reducing surgical site infections following colorectal resections. A systematic review
Ontology highlight
ABSTRACT: Objective
The objective of this article is to explore whether the use of single or double ringed wound protectors (WP) in patients undergoing colorectal resection (CRR) are associated with reduced risk of surgical site infections (SSI). Materials and methods
Analysis was conducted according to PRISMA guidelines. With the help of expert local librarians, systematic search of medical databases like MEBASE, MEDLINE and PubMed was conducted to find appropriate randomized controlled trials (RCT) according to predefined inclusion criteria. The analysis of the pooled data was done using the principles of meta-analysis on statistical software RevMan version 5. Result
Twelve RCT on 2425 patients fulfilled the inclusion criteria. There were 1216 patients in the WP group and 1209 patients in the no-WP group. In the random effects model analysis, the use of WP during CRR was associated with the reduced risk of SSI [odds ratio 0.60, 95% CI (0.41–0.90), z = 2.49, P = 0.01]. However, there was significant heterogeneity (Tau2 = 0.22; Chi2 = 25.87, df = 11; (p = 0.007; I2 = 57%) among included studies. Conclusion
Use of WP seems to reduce the risk of SSI and therefore, may routinely be used during both open and laparoscopic CRR. Highlights • Surgical site infections (SSIs) are a frequent complication following major abdominal surgery.• The aim is to assess the effectiveness of using wound protectors in decreasing post operative SSIs in colorectal resection.• Twelve RCTs were used to obtain the submitted data.• Using wound protectors was associated with reduced post operative SSIs in colorectal resections.

Project description:BackgroundSurgical site infection (SSI) is a common complication after abdominal surgery. The effectiveness of wound edge protectors in reducing infection of the surgical sites is still unclear. The purpose of this study was to determine the clinical effectiveness of a wound edge protector (WEP) in reducing SSI rates after abdominal surgery.MethodsPubMed, Embase, Web of Science, and the Cochrane Library were systematically searched to obtain relevant articles published up to September 2021. Publications were retrieved if they contain primary data on the use of WEPs in reducing SSI compared with standard care in patients undergoing abdominal surgery. Subgroup analyses were performed for different WEP types, surgical sites, and levels of contamination. The outcome of interest was a clinically defined SSI. Qualitative variables were pooled using risk ratios (RRs).ResultsTwenty-two eligible randomized clinical trials involving 4492 patients were included in this meta-analysis. WEP was associated with the reduced incidence of overall SSI (RR = 0.66; 95 per cent c.i. 0.53 to 0.83; P = 0.0003), and superficial SSI (RR = 0.59; 95 per cent c.i. 0.38 to 0.91; P = 0.02). In addition, WEP also successfully reduced the risk of SSI in clean-contaminated wounds (RR = 0.61; 95 per cent c.i. 0.40 to 0.93; P = 0.02) as well as in contaminated wounds (RR = 0.47; 95 per cent c.i. 0.33 to 0.67; P < 0.0001); however, WEP did not reduce SSI incidence in colorectal surgery (RR = 0.68; 95 per cent c.i. 0.46 to 1.01; P = 0.05).ConclusionThis study suggests that WEP was efficient in reducing superficial SSI. Both double-ringed and single-ringed devices were efficient in reducing SSI. WEP was effective in reducing SSI incidence in clean-contaminated and contaminated surgery; however, its use does not reduce the SSI rate in colorectal surgery.

Project description:ImportanceSurgical site infections remain one of the most frequent complications following abdominal surgery and cause substantial costs, morbidity and mortality.ObjectiveTo assess the effectiveness of wound edge protectors in open abdominal surgery in reducing surgical site infections.Evidence reviewA systematic literature search was conducted according to a prespecified review protocol in a variety of data-bases combined with hand-searches for randomized controlled trials on wound edge protectors in patients undergoing laparotomy. A qualitative and quantitative analysis of included trials was conducted.FindingsWe identified 16 randomized controlled trials including 3695 patients investigating wound edge protectors published between 1972 and 2014. Critical appraisal uncovered a number of methodological flaws, predominantly in the older trials. Wound edge protectors significantly reduced the rate of surgical site infections (risk ratio 0.65; 95%CI, 0.51-0.83; p = 0.0007; I2 = 52%). The results were robust in a number of sensitivity analyses. A similar effect size was found in the subgroup of patients undergoing colorectal surgery (risk ratio 0.65; 95%CI, 0.44-0.97; p = 0.04; I2 = 56%). Of the two common types of wound protectors double ring devices were found to exhibit a greater protective effect (risk ratio 0.29; 95%CI, 0.15-0.55) than single-ring devices (risk ratio 0.71; 95%CI, 0.54-0.92), but this might largely be due to the lower quality of available data for double-ring devices. Exploratory subgroup analyses for the degree of contamination showed a larger protective effect in contaminated cases (0.44; 95%CI, 0.28-0.67; p = 0.0002, I2 = 23%) than in clean-contaminated surgeries (0.72, 95%CI, 0.57-0.91; p = 0.005; I2 = 46%) and a strong effect on the reduction of superficial surgical site infections (risk ratio 0.45; 95%CI, 0.24-0.82; p = 0.001; I2 = 72%).Conclusions and relevanceWound edge protectors significantly reduce the rate of surgical site infections in open abdominal surgery. Further trials are needed to explore their effectiveness in different risk constellations.

Project description:BackgroundSurgical site infections (SSIs) are a frequent postoperative complication that nurses commonly need to provide asepsis-specific meticulous care for. The application of a closed-incisional negative pressure wound therapy (iNPWT) device is regarded as a novel technique that aims to lower the risk of external wound contamination.AimThe purpose of this review was to evaluate the effectiveness of iNPWT on high-risk closed laparotomy incisions with the aim to inform nursing practitioners and physicians engaged in multieffort wound care practices. Nursing professionals play a crucial role in mitigating the incidence of SSIs, from the time of application, through ongoing assessment tissue condition, and ensuring asepsis, thereby enhancing patient care and safety.The research questionIs prophylactic negative pressure wound therapy effective in reducing the incidence of (closed) surgical site wound infections postlaparotomy?Pico elementsThe population studied included patients undergoing laparotomy surgery. The intervention under review included the application of iNPWT, compared to the use of standard gauze dressing. The expected outcome was SSI reduction.Methods and resultsA systematized literature search was conducted using various databases to identify published studies that address the PICO question. The PRISMA checklist and Critical Appraisal Skills Programme tools allowed to exclude irrelevant articles and to critically appraise the evidence, respectively. Eleven key articles were retrieved including four RCTs and seven systematic reviews and meta-analysis. The results indicated an overall positive association between iNPWT and a reduction in SSI in laparotomy surgeries when compared to standard dressings.Linking evidence to actionData across most studies reviewed support the benefits with the use of iNPWT as a preventive strategy to lower the rates of SSI, with some claiming no difference. Although heterogeneity in the studies precludes a definite conclusion, nurses may make a more informed decision when navigating the demands of SSI prevention targeted nursing care.

Project description:OBJECTIVE:To examine the association of a resident-driven quality initiative with cesarean delivery surgical site infections. METHODS:This was a quasi-experimental, preintervention and postintervention study of women undergoing cesarean delivery at 23 weeks of gestation or greater between January 2015 and June 2018 at a single tertiary care center. We implemented a resident-driven, evidence-based surgical bundle, excluding women who underwent emergency cesarean or had chorioamnionitis. The bundle included routine prophylactic antibiotics (both cefazolin and azithromycin), chlorhexidine alcohol skin preparation, use of clippers instead of a razor, vaginal cleansing with povidone iodine, placental removal by umbilical cord traction, subcutaneous tissue closure if wound thickness greater than 2 cm, suture skin closure, dressing removal between 24 and 48 hours, and use of postoperative chlorhexidine soap. Our primary outcome was surgical site infections (superficial incisional, deep incisional, and organ or space surgical site infections) occurring up to 6 weeks postpartum. Outcomes were compared between the preimplementation period (January 2015-August 2016) and postimplementation period (December 2016-June 2018). Coarsened Exact Matching with k-to-k solution was performed using age, race-ethnicity, body mass index, rupture of membranes, and labor. RESULTS:In total, 1,624 underwent cesarean delivery in the preimplementation and 1,523 postimplementation periods, respectively; 1,100 women in the postimplementation period were matched to 1,100 women in the preimplementation period. The rate of surgical site infections in the unmatched cohort was significantly lower in the postimplementation period compared to those in the preimplementation period (2.2% [33/1,523] vs 4.5% [73/1,624]; odds ratio [OR] 0.47 [95% CI 0.31-0.71]; P<.001). This decrease in the rate of surgical site infections remained statistically significant after matching (1.9% [21/1,100] vs 4.1% [45/1,100]; OR 0.46 [0.27-0.77]; P<.001). CONCLUSION:After implementation of a resident-driven quality initiative using a surgical bundle, we observed a significant decrease in cesarean surgical site infections.

Project description:ObjectiveTo investigate the role of wound protectors (WPs) in surgical site infection (SSI) prevention in patients undergoing abdominal surgery.BackgroundDespite practitioners having pursued the ultimate aim of "getting to zero" for centuries, SSI is still a global healthcare burden. WPs are thought to be able to prevent the incision from bacterial contamination, however, contradictory results have been reported.MethodA meta-analysis was performed to compare the SSI rate in patients with and without WPs after abdominal surgery. It includes subgroup analysis of the SSI rate in different surgical sites and different degrees of wound contamination. A systematic literature search was conducted in the PubMed, Embase, Cochrane Library databases, and Web of Science from their respective inceptions until July 6, 2024. All randomized controlled trials with consistent definitions of SSI were included. The bias of each included RCT was assessed by using the Cochrane Risk of Bias 2. To evaluate the risks of random errors resulting from repeated significant testing, a trial sequential analysis was performed. The quality of evidence was assessed by using GRADEpro Guideline Development Tool.ResultsA total of 4779 participants were involved in the 19 RCTs. The results showed that the application of WPs during abdominal surgery could significantly reduce the SSI rate (RR = 0.63, 95% CI: 0.50-0.80, P = 0.0001, very low certainty evidence). Subgroup analysis showed that the implementation of WPs significantly reduced the SSI rate after colorectal and gastrointestinal surgery (RR = 0.58, 95% CI: 0.38-0.91, P = 0.02, very low certainty evidence; RR = 0.49, 95% CI: 0.36-0.67, P < 0.00001, moderate certainty evidence, respectively), while had no clear protect role in other types of abdominal surgery. The WPs significantly reduced the SSI rate in patients with a clean-contaminated wound (RR = 0.64, 95% CI: 0.46-0.89, P = 0.008, very low certainty evidence) and contaminated or dirty wound (RR = 0.61, 95% CI: 0.41-0.92, P = 0.02, moderate certainty evidence), respectively.ConclusionsThe results indicated that the WPs should not be used indiscriminately in all abdominal but gastrointestinal surgery. For patients with contaminated or dirty incisions, WPs should be considered. More studies are needed to determine the effect of WPs in laparoscopic surgery.Clinical trial numberNot applicable.

Project description:ImportanceSurgeons are increasingly interested in using mobile and online applications with wound photography to monitor patients after surgery. Early work using remote care to diagnose surgical site infections (SSIs) demonstrated improved diagnostic accuracy using wound photographs to augment patients' electronic reports of symptoms, but it is unclear whether these findings are reproducible in real-world practice.ObjectiveTo determine how wound photography affects surgeons' abilities to diagnose SSIs in a pragmatic setting.Design, setting, and participantsThis prospective study compared surgeons' paired assessments of postabdominal surgery case vignettes with vs without wound photography for detection of SSIs. Data for case vignettes were collected prospectively from May 1, 2007, to January 31, 2009, at Erasmus University Medical Center, Rotterdam, the Netherlands, and from July 1, 2015, to February 29, 2016, at Vanderbilt University Medical Center, Nashville, Tennessee. The surgeons were members of the American Medical Association whose self-designated specialty is general, abdominal, colorectal, oncologic, or vascular surgery and who completed internet-based assessments from May 21 to June 10, 2016.InterventionSurgeons reviewed online clinical vignettes with or without wound photography.Main outcomes and measuresSurgeons' diagnostic accuracy, sensitivity, specificity, confidence, and proposed management with respect to SSIs.ResultsA total of 523 surgeons (113 women and 410 men; mean [SD] age, 53 [10] years) completed a mean of 2.9 clinical vignettes. For the diagnosis of SSIs, the addition of wound photography did not change accuracy (863 of 1512 [57.1%] without and 878 of 1512 [58.1%] with photographs). Photographs decreased sensitivity (from 0.58 to 0.50) but increased specificity (from 0.56 to 0.63). In 415 of 1512 cases (27.4%), the addition of wound photography changed the surgeons' assessment (215 of 1512 [14.2%] changed from incorrect to correct and 200 of 1512 [13.2%] changed from correct to incorrect). Surgeons reported greater confidence when vignettes included a wound photograph compared with vignettes without a wound photograph, regardless of whether they correctly identified an SSI (median, 8 [interquartile range, 6-9] vs median, 8 [interquartile range, 7-9]; P < .001) but they were more likely to undertriage patients when vignettes included a wound photograph, regardless of whether they correctly identified an SSI.Conclusions and relevanceIn a practical simulation, wound photography increased specificity and surgeon confidence, but worsened sensitivity for detection of SSIs. Remote evaluation of patient-generated wound photographs may not accurately reflect the clinical state of surgical incisions. Effective widespread implementation of remote postoperative assessment with photography may require additional development of tools, participant training, and mechanisms to verify image quality.

Project description:BackgroundSurgical-site infection (SSI) is associated with significant healthcare costs. To reduce the high rate of SSI among patients undergoing colorectal surgery at a cancer centre, a comprehensive care bundle was implemented and its efficacy tested.MethodsA pragmatic study involving three phases (baseline, implementation and sustainability) was conducted on patients treated consecutively between 2013 and 2016. The intervention included 13 components related to: bowel preparation; oral and intravenous antibiotic selection and administration; skin preparation, disinfection and hygiene; maintenance of normothermia during surgery; and use of clean instruments for closure. SSI risk was evaluated by means of a preoperative calculator, and effectiveness was assessed using interrupted time-series regression.ResultsIn a population with a mean BMI of 30 kg/m2 , diabetes mellitus in 17·5 per cent, and smoking history in 49·3 per cent, SSI rates declined from 11·0 to 4·1 per cent following implementation of the intervention bundle (P = 0·001). The greatest reductions in SSI rates occurred in patients at intermediate or high risk of SSI: from 10·3 to 4·7 per cent (P = 0·006) and from 19 to 2 per cent (P < 0·001) respectively. Wound care modifications were very different in the implementation phase (43·2 versus 24·9 per cent baseline), including use of an overlying surface vacuum dressing (17·2 from 1·4 per cent baseline) or leaving wounds partially open (13·2 from 6·7 per cent baseline). As a result, the biggest difference was in wound-related rather than organ-space SSI. The median length of hospital stay decreased from 7 (i.q.r. 5-10) to 6 (5-9) days (P = 0·002). The greatest reduction in hospital stay was seen in patients at high risk of SSI: from 8 to 6 days (P < 0·001). SSI rates remained low (4·5 per cent) in the sustainability phase.ConclusionMeaningful reductions in SSI can be achieved by implementing a multidisciplinary care bundle at a hospital-wide level.

Project description:Recent studies have implied a prognostic value of the prognostic nutritional index (PNI) in postoperative septic complications of elective colorectal surgeries. However, the evaluation of PNI in contaminated surgeries for gastrointestinal (GI) fistula patients is lack of investigation. The purpose of this study was to explore the predictive value of PNI in surgical site infections (SSIs) for GI fistula patients undergoing bowel resections.A retrospective review of 290 GI patients who underwent intestinal resections between November 2012 and October 2015 was performed. Univariate and multivariate analyses were conducted to identify risk factors for SSIs, and receiver operating characteristic cure was used to quantify the effectiveness of PNI.SSIs were diagnosed in 99 (34.1%) patients, with incisional infection identified in 54 patients (18.6%), deep incisional infection in 13 (4.5%), and organ/space infection in 32 (11.0%). receiver operating characteristic curve analysis defined a PNI cut-off level of 45 corresponding to postoperative SSIs (area under the curve [AUC] = 0.72, 76% sensitivity, 55% specificity). Furthermore, a multivariate analysis indicated that the PNI?<?45 [odd ratio (OR): 2.24, 95% confidence interval (CI): 1.09-4.61, P = 0.029] and leukocytosis (OR: 3.70, 95% CI: 1.02-13.42, P = 0.046) were independently associated with postoperative SSIs.Preoperative PNI is a simple and useful marker to predict SSIs in GI fistula patients after enterectomies. Measurement of PNI is therefore recommended in the routine assessment of patients with GI fistula receiving surgical treatment.

Project description:BackgroundSurgical site infection (SSI) is one of the leading complications in health care. Negative pressure wound therapy (NPWT) is meanwhile widely prophylactically used for preventing SSIs. For evaluating the results of the implantation of this technique, we used the Simon single-arm study design and examine whether NPWT has a prophylactic effect on reducing SSIs in a cohort of general surgery patients.MethodsThis single-arm, two-stage study includes 81 elective general surgery patients and corresponds to the Simon's design. The sample size calculation was based on a reduction in the superficial SSI rate from 12 to 4% (power 80%, significance level 5%) using a NPWT system. In compliance with Simon's two-Stage design, the study required the recruitment of 34 patients in stage I and 47 patients in stage II. The two-stage design method would be discarded in case of a wound infection in 3 or more patients in stage I or 6 or more patients in stage II. Using the NPWT system in the operating room, a negative pressure wound dressing was applied post-operatively and removed after 7 days. According to the criteria of the Centres for Disease Control and Prevention (CDC), post-operative wound documentation followed on day 7 and 30.ResultsIn stage I, no SSI was apparent. In stage II, 3 patients had SSIs (CDC grade I).ConclusionA prophylactic NPWT can significantly reduce the wound infection rate in elective general surgery.

Project description:Surgical site infections (SSIs) are important healthcare-associated infections, leading to increased morbidity and mortality, healthcare costs, and prolonged hospital stays. Staphylococcus aureus is an important and common microbial cause of SSI. Nasal carriage of S. aureus has been shown to be an important determinant for the development of SSI, and interventions aimed at eradicating preoperative nasal carriage are associated with a reduced risk of infection. Yet, it is not entirely clear how the nasally residing S. aureus causes SSI at distant body sites. In this commentary, we describe our view on how S. aureus can be transported from the nares to the incision site during surgery. In addition, we shed light on the implications of our view for infection prevention research.
