Lower Surgical Site Infection Rates Research Articles

A novel zipper device versus sutures for wound closure after surgery: a systematic review and meta-analysis.

We performed an updated meta-analysis to compare the efficacy of the zipper device and sutures for wound closure after surgery. A computerised literature search was performed for published trials in PubMed, Web of Science, the Cochrane Library, and Google Scholar. Two reviewers independently scrutinised the trials, extracted data, and assessed the quality of trials. The primary outcome was surgical site infections (SSI). The secondary outcomes were wound dehiscence, total wound complications, wound closure time, and scar score. Statistical analysis was performed in the Stata 12.0. Of the 130 citations, eight trials (1207 participants) met eligibility criteria and were included. The zipper device achieved a lower SSI rate (RR: 0.63, [95% CI: 0.41-0.96, P = 0.032]), a shorter wound closure time (SMD: -8.53 [95% CI: -11.93 to -5.13, P = 0.000]) and a better scar score (SMD: 0.42 [95% CI: 0.22-0.62, P = 0.000]) than sutures. No significant difference was shown in the incidence of wound dehiscence and total wound complications. Therefore, the zipper device provides the advantages of anti-infection, time-saving, and cosmesis for wound closure.

Wound complications after total hip arthroplasty: a prospective, randomised controlled trial comparing staples with sutures.

Does the use of staples or sutures for wound closure have a lower surgical site infection rate in patients receiving primary total hip arthroplasty (THA)? Prospective, randomised controlled multicentre trial. 535 patients undergoing THA were included and randomised into 2 groups: 268 wounds were closed with staples, and 267 with sutures. Primary outcome was surgical site infection (SSI). Secondary outcomes were prosthetic joint infection (PJI), other wound complications (dehiscence, necrosis and prolonged drainage) and duration of admittance. Follow-up occurred at 2, 6, and 12 weeks, and at 1 year. There were no significant demographic differences between the 2 groups. SSI occurred more frequently when wounds were closed with staples (4% compared to 1% with sutures; OR 2.8; CI, 0.885-0.952; p = 0.057). SSI was treated with oral antibiotics. The staples group showed significantly more wound complications (17% compared to 5%; OR 3.943, CI 2.073-7.498; p = 0.000). Wound discharge was significantly prolonged in the staples group (n = 40, compared to n = 12 in the sutures group; OR 3.728; CI, 1.909-7.281; p = 0.000). There was no significant difference in PJI (p = 0.364). In this large RCT comparing staples with sutures after THA, the use of staples is associated with a nearly 3 times greater risk of SSI (OR 2.8; p = 0.057). Staples significantly prolong wound discharge. The use of sutures for wound closure after THA is advised.

Implementation of an Abdominal Closure Bundle in Patients Undergoing Cesarean Section—A Randomized Control Trial [15P

INTRODUCTION: Surgical site infections (SSI) are associated with increased morbidity, mortality, and healthcare costs. Literature in Colorectal Surgery and Gynecologic Oncology have suggested lower SSI rates among patients who receive closure bundles. This study investigated whether implementation of an abdominal closure bundle reduces SSI rates in patients undergoing cesarean section. METHODS: We conducted a prospective randomized controlled trial of patients who underwent a scheduled cesarean section. Enrolled patients were randomized to either standard operative procedure or the abdominal closure bundle. The bundle included changing of the surgical gown and gloves, repeat scrub, and usage of new instruments for closure of fascia, subcutaneous tissue, and skin. SSI rates were assessed and predictors of SSI were determined. RESULTS: 241 patients were included in this interim analysis. No difference in SSI was found between the control (3/130, 2.3%) and closure bundle (2/111, 1.8%) groups (P=1.00). Logistic regression indicated that smoking status and number of prior cesarean sections were statistically reliable predictors of SSI (P=.009). Former or active smokers were 8.3 times more likely to have an infection (CI 1.61 – 43.3, P=.012). Those with prior cesarean sections were 2.5 times more likely to have an infection (CI 1.0 – 6.1, P=.045). CONCLUSION: Implementation of an abdominal closure bundle for patients undergoing scheduled cesarean sections did not significantly reduce SSI rate. We plan to investigate the impact of the abdominal closure bundle in a higher risk population as completion of this study as designed is unlikely to reach statistical significance.

Surveillance of surgical-site infections and antimicrobial resistance patterns in a tertiary hospital in Alexandria, Egypt.

Surveillance and antimicrobial resistance (AMR) monitoring are fundamental to Health care associated infections control. Limited data are available from developing countries for both. This study aimed to evaluate incidence and risk factors of surgical site infections (SSIs), etiological pathogens and AMR patterns identification. A prospective active surveillance study was implemented over a 24- month period at a 110-bed multispecialty non-teaching tertiary hospital. Follow up data were collected for 30-90 days. SSI was diagnosed according to Centers for Disease Control and Prevention and National Healthcare Safety Network (CDC/NHSN) criteria. The SSI isolates were identified by Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDITOF/MS). Antibiotics susceptibility test was performed according to Clinical Laboratory Standards Institute (CLSI) and European Committee on Antimicrobial Susceptibility Testing (EUCAST). Out of a total of 3,642 patients, 70% had complete follow-up. SSI was detected in 57 cases (2.3%), 61.4% of which were detected post discharge. Factors significantly associated with increased SSI risk included smoking, diabetes, ASA score 5/E, ICU admission, previous admission and increased hospital stay. Sixty-five isolates were obtained; 70.8% were GNB while 24.6% were GPC and 4.6% were Candida albicans. Regarding AMR, 58.7% of isolates were extended spectrum β lactamase (ESBL) producers while 45.7% were Carbapenem resistant. Multi drug resistant (MDR) was detected in 13% of isolates, 54.3% were extended drug resistant (XDR) and 10.9% were pan drug resistant (PDR). Eighty-six percent of Staphylococci isolates were methicillin-resistant. Despite low SSI rates detected, the high incidence of AMR identified is alarming.

Preoperative Bowel Preparation in Minimally Invasive and Vaginal Gynecologic Surgery.

Bowel preparation traditionally refers to the removal of bowel contents via mechanical cleansing measures. Although it has been a common practice for more than 70 years, its use is based mostly on expert opinion rather than solid evidence. Mechanical bowel preparation in minimally invasive and vaginal gynecologic surgery is strongly debated, since many studies have not confirmed its effectiveness, neither in reducing postoperative infectious morbidity nor in improving surgeons' performance. A comprehensive search of Medline/PubMed and the Cochrane Library Database was conducted, for related articles up to June 2019, including terms such as “mechanical bowel preparation,” “vaginal surgery,” “minimally invasive,” and “gynecology.” We aimed to determine the best practice regarding bowel preparation before these surgical approaches. In previous studies, bowel preparation was evaluated only via mechanical measures. The identified randomized trials in laparoscopic approach and in vaginal surgery were 8 and 4, respectively. Most of them compare different types of preparation, with patients being separated into groups of oral laxatives, rectal measures (enema), low residue diet, and fasting. The outcomes of interest are the quality of the surgical field, postoperative infectious complications, length of hospital stay, and patients' comfort during the whole procedure. The results are almost identical regardless of the procedure's type. Routine administration of bowel preparation seems to offer no advantage to any of the objectives mentioned above. Taking into consideration the fact that in most gynecologic cases there is minimal probability of bowel intraluminal entry and, thus, low surgical site infection rates, most scientific societies have issued guidelines against the use of any bowel preparation regimen before laparoscopic or vaginal surgery. Nonetheless, surgeons still do not use a specific pattern and continue ordering them. However, according to recent evidence, preoperative bowel preparation of any type should be omitted prior to minimally invasive and vaginal gynecologic surgeries.

Measures to reduce end-of-case wound contamination: the impact of intra-wound vancomycin powder and betadine irrigation on surgical site infections in posterior spinal fusion.

Retrospective descriptive, single-center study. To determine the effect of standardized intrawound vancomycin powder and betadine irrigation on surgical site infection (SSI) rates after posterior spinal fusion (PSF) in idiopathic scoliosis. Since 2005, our pediatric spine center has implemented a series of changes to lower the risk of SSI. The most recent interventions-intrawound vancomycin powder and betadine irrigation-are applied just before closure, aiming to reduce the culture-positive bacterial contamination known to occur in many cases. We sought to determine the impact of these end-of-case measures on our center's SSI rate. We retrospectively reviewed patients who underwent PSF for idiopathic scoliosis at our institution from January 1, 2010, to June 30, 2018, identifying all cases that returned to the operating room for surgical debridement within 90days of PSF. Cases were surgeon-audited to ensure inclusion of all infections that met Centers for Disease Control and Prevention (CDC) criteria for acute SSI. Vertical expandable prosthetic titanium ribs, growing rods, staged procedures, and nonidiopathic cases were excluded. Annual rates of SSIs were correlated with the initiation of each SSI prevention measure. Among 740 cases of PSF for idiopathic scoliosis from 2010 to 2018, the overall acute SSI rate by CDC criteria was 0.68%. The idiopathic SSI rate dropped significantly, from 1.70 to 0.20%, after the standardized introduction of intrawound vancomycin powder and betadine irrigation before closure (p < 0.04). The implementation of these end-of-case measures in 2012-2013 was soon followed by an institution best 3.5-year SSI-free period for idiopathic cases. Since intrawound vancomycin powder and betadine irrigation were added to our SSI prevention bundle, we have seen a significantly lower SSI rate after PSFs for idiopathic scoliosis. These findings suggest that anti-SSI interventions to reduce wound contamination at the end of the case may have a particularly positive impact on SSI reduction. Level III, therapeutic.

Comparison of Postoperative Surgical-Site Infection and Symptomatic Intracranial Hemorrhage between Staged and Simultaneous Cranioplasty with Ventriculoperitoneal Shunt Placement: A Meta-Analysis.

ObjectiveConsensus about the sequence of cranioplasty and ventriculoperitoneal shunt placement to reduce postoperative complications has not been established. This meta-analysis investigated and collated further evidence to determine whether staged cranioplasty with ventriculoperitoneal shunt placement would significantly reduce the risk of postoperative surgical-site infection (SSI) and symptomatic intracranial hemorrhage.MethodsTwo independent reviewers identified articles and extracted the data of patients who underwent cranioplasty and ventriculoperitoneal shunt placement from PubMed, Embase, and Cochrane Central Register of Controlled Trials. A random effects model was used to compare the complication rates using odd ratios (ORs) and 95% confidence intervals (CIs). A meta-regression analysis for traumatic brain injury (TBI) was additionally performed.ResultsData from 7 studies with 391 patients were consecutively included. The meta-analysis revealed that staged surgery was significantly associated with lower rates of SSI after decompressive craniectomy (staged group vs. simultaneous group: 6.2% vs. 23.7%, OR: 2.72, 95% CI: 1.46–5.06, I2=2.4%, p=0.407). Pooled analysis did not indicate a statistically significant difference between the 2 groups for symptomatic intracranial hemorrhage (staged group vs. simultaneous group: 10.4% vs. 23.0%, OR: 1.66, 95% CI: 0.74–3.73, I2=0.0%, p=0.407). The meta-regression analysis did not indicate any modifying effect of TBI on postoperative SSI development (p=0.987).ConclusionThis meta-analysis indicated that staged surgery is significantly associated with a lower rate of postoperative SSI as compared with simultaneous surgery, but there is no difference in symptomatic intracranial hemorrhage. Additionally, there is no modifying effect of TBI on SSI.

Evaluation of the use of component separation in elderly patients: results of a large cohort study with 30-day follow-up.

The incidence of massive ventral hernias among the elderly will increase as the population ages. Advanced age is often viewed as a contraindication to elective hernia repair. A relationship between age and complications of component separation procedures for ventral hernias is not well established. This study evaluated the effect of age on the peri-operative safety of AWR. The 2005-2013 ACS-NSQIP participant use data were reviewed to compare surgical site infection (SSI), overall morbidity, and serious morbidity in non-emergent component separation procedures among all age groups. All patients were stratified into four age quartiles and evaluated. Baseline characteristics included age, body mass index (BMI) and ASA 3 or 4 criteria. Statistical analysis was performed using SPSS. Odds ratios (OR) and 95% confidence intervals were reported as appropriate. 4485 patients were identified. Majority of the cases were clean (76.8%). Patients were divided into the following quartiles based on age. The older quartile had a mean age of 72.7 ± 4.87years. There were baseline differences in BMI and chronic comorbidity severity (measured by incidence of ASA score of 3 or 4) between the age groups, with the oldest group having lower BMI but higher rate of ASA 3 or 4 (p < 0.0001 for both). The rate of postoperative SSI was significantly different between age quartile groups (ranging from 16.3% from the youngest group to 9.4% for the oldest group, p < 0.0001). After adjusting for other baseline differences, advanced age was independently associated with lower SSI rate (OR 0.55, 95% CI 0.41-0.73). There was no significant difference in overall morbidity (p = 0.277) and serious morbidity (p = 0.131) between groups. AWR is being performed with safety across all age groups. In selected patients of advanced age, AWR can be performed with similar safety profile and low SSI rate.

Association of Open Approach vs Laparoscopic Approach With Risk of Surgical Site Infection After Colon Surgery

Colon surgery is associated with a high rate of surgical site infection (SSI), and there is an urgent need for strategies to reduce infection rates. To assess whether laparoscopic colon surgery is associated with a lower surgical site infection rate than open-approach laparoscopy, especially in patients with medically complex conditions. This cohort study used previously validated diagnosis and procedure codes from Medicare beneficiaries who underwent colon surgery from January 1, 2009, to November 30, 2013. Analyses were performed from August 1 to December 31, 2018. Outcome measures were SSI events, medical comorbidities, and laparoscopic or open approach procedures. A total of 229 726 patients (mean [SD] age, 74.3 [9.4] years; 128 499 [55.9%] female) underwent colon procedures. There were 105 144 laparoscopic procedures and 124 582 open procedures. The overall mean SSI rate was 6.2%, varying by surgical procedure from 5.8% to 7.6%. Among the full study population, adjusted model results showed a significant association of laparoscopy with lower odds of SSI (odds ratio, 0.43; 95% CI, 0.41-0.46; P < .001). When stratified by surgical approach, the mean SSI rates were 4.1% (procedure-specific range, 3.9%-5.1%) for the laparoscopic approach and 7.9% (procedure-specific range, 7.4%-10.2%) for the open approach. When stratified by Elixhauser score groups, the mean SSI rates were 6.2% (procedure-specific range, 3.2%-8.7%) for group 1 (0-1 comorbidity), 5.5% (procedure-specific range, 3.6%-11.1%) for group 2 (2 comorbidities), and 6.6% (procedure-specific range, 4.6%-10.6%) for group 3 (3-13 comorbidities). An interaction was also observed between laparoscopic approach and Elixhauser groups, with increased odds of SSI among patients who had 3 to 13 comorbidities present at the time of the procedure (odds ratio, 1.21; 95% CI, 1.11-1.32) compared with patient groups with fewer comorbidities. The population attributable fraction of SSIs for use of the open approach was 34.2%. A total of 2317 of 3882 hospitals (59.7%) performed few (0%-10%) or most (>50%) procedures laparoscopically. Policy changes that promote surgical education and resources for laparoscopy, especially at low-adoption hospitals, may be associated with reduced colon SSI rates. Support of the development of innovative educational policies may help achieve improvement in patient outcomes and decreased health care use in colon surgery.

Best Practices in Data Use for Achieving Successful Implementation of Enhanced Recovery Pathway

Although enhanced recovery pathways (ERPs) have demonstrated promising results in published literature, their effectiveness has been inconsistent. The objective of this study was to identify the most important data use practices associated with successful implementation of ERPs. As part of a national ERP implementation initiative, data regarding hospitals' previous ERP implementation experience were collected. Specifically, 4 data use practices (data collection, report generation, feedback to leadership, and feedback to frontline providers) and 2 data types (process measures and outcome measures) were correlated with ERP implementation outcomes (hospital-reported success and patient outcomes from the American College of Surgeons [ACS] NSQIP data). Of 140 hospitals evaluated, 73 (52.1%) reported previous ERP implementation, with wide variations in data use practices. Of these, 33 (45.2%) reported successful implementation. Feedback of both process and outcome measure data was performed by only 15.1% of hospitals, but was associated with significantly higher likelihood of successful implementation when compared with no feedback (relative risk [RR] 2.45, 95% CI 1.69 to 3.56; p < 0.001) and feedback of only outcome measure data (RR 2.73, 95% CI 1.06 to 7.00; p= 0.037). Using ACS NSQIP data from 6,888 colorectal surgery patients from 52 hospitals with colorectal ERPs, hospital-reported success was associated with significantly lower surgical site infection rates (6.6% vs 8.1%; p= 0.011) and shorter length of stay (6.2 vs 7.0 days; p < 0.001). The most important data use practice associated with successful ERP implementation was data feedback to frontline providers of both process and outcome measures. However, this was rarely performed in a national cohort of hospitals and represents a substantial but straightforward opportunity for improvement.

2186 Towards Zero SSIs: Incisional Negative Pressure Wound Therapy in High Risk Gynecologic Surgery Patients May Reduce Infections but not Overall Wound Complications

Study Objective Identify whether incisional (or prophylactic) negative-pressure wound therapy (iNPWT) is associated with reduced wound complications. Design Retrospective cohort study. Setting Quaternary referral academic center. Patients or Participants Included patients underwent an open abdominal procedure for a gynecologic indication with a gynecologic primary surgeon between July 1, 2015 and June 30, 2017. Type III or IV incisions were excluded. A total of 568 patients met inclusion criteria. Interventions iNPWT placed over a closed incision. Measurements and Main Results We compared our intervention group of patients who had 1+ additional risk factor and received iNPWT (Group A) to a group of patients managed by gynecologic surgeons who never use iNPWT (Group B) and to a cohort who did not receive iNPWT, but were managed by gynecologic surgeons who use iNPWT (Group C). The primary outcome was a composite of wound complications, including surgical site infections (SSIs), hematomas, seromas, or wound separations, within 30 days following surgery. Results were adjusted using inverse probability weighting. The unadjusted wound complication rates were 18.3%, 13.4% and 16.8%, in Groups A (N=71), B (N=283), and C (N=214), respectively, and were not significantly different. The adjusted rates were similar for overall wound complications but did show a lower SSI rate between Groups A and B (6.7% vs 8.2%) and groups A and C (5.0% vs 10.0%). A subgroup of patients with a BMI >40 kg/m2 and 1 additional risk factor showed similar SSI rates (10.5% vs 10.3%) between Groups A and C, and a lower rate in Group A when compared to Group C (10.5% vs 20.0%). However, SSI rate differences did not reach statistical significance due to low numbers. Conclusion There was no difference in overall wound complication rates among patients receiving iNPWT. Lower SSI rates were seen although statistical significance was not reached. iNPWT as an intervention may impact SSIs more than hematomas, seromas, and wound separations.

No Reduction in Surgical Site Infection Obtained with Post-Operative Antibiotics in Facial Fractures, Regardless of Duration or Anatomic Location: A Systematic Review and Meta-Analysis.

Background: We performed a systematic review of the literature on antibiotic prophylaxis practices in open reduction, and internal fixation of, facial fracture(s) (ORIFfx). We hypothesized that prolonged antibiotic prophylaxis (PAP) would not decrease the rate of surgical site infections (SSIs). Methods: We performed a systematic review of four databases: PubMed, CENTRAL, EMBase, and Web of Science, from inception through January 15, 2017. Three independent reviewers extracted fracture location (orbital, mid-face, mandible), antibiotic use, SSI incidence, and time from injury to surgery. Mantel-Haenszel and generalized estimating equations were carried out independently for each fracture zone. Results: Of the 587 articles identified, 54 underwent full-text review, yielding 27 studies that met our inclusion criteria. Of these, 16 studies (n = 2,316 patients) provided data for mandible fractures, four studies (n = 439) for mid-face fractures, and six studies (n = 377) for orbital fractures. Pooled analysis of each fracture type's SSI rate showed no statistically significant association with the odds ratio (OR) of developing an SSI. For mandible fractures treated with ORIFfx, the OR for an SSI after 24-72 hours of prophylaxis relative to <24 hours was 0.85 (95% confidence interval [CI] 0.62-1.17), whereas for >72 hours compared with <24 hours, the OR was 1.42 (95% CI) 0.96-2.11). For mid-face fractures, there was no improvement in SSI rate from PAP (OR 1.05; 95% CI 0.20-5.63). Conclusions: We did not demonstrate a lower rate of SSI associated with PAP for any ORIFfx repair. Post-operative antibiotics for >72 hours paradoxically may increase the SSI risk after mandible fracture repairs.

Does a Care Bundle Reduce Racial Disparities in Postcesarean Surgical Site Infections?

To examine the effect of a care bundle on racial disparities in surgical site infections (SSIs). This was a retrospective cohort study of women undergoing cesarean delivery at ≥23 weeks' gestation. The care bundle included routine antibiotics (both cefazolin and azithromycin), chlorhexidine skin preparation, clippers, vaginal cleansing, placental removal by cord traction, subcutaneous tissue closure, suture skin closure, dressing removal in 24 to 48 hours, and postoperative chlorhexidine soap. Our primary outcome was SSI (superficial incisional, deep incisional, and organ/space) occurring up to 6 weeks. Adjusted odds ratios (aOR) with 95% confidence intervals (95% CI) were calculated, adjusting for predefined covariates. Of 2,696 women, 1,947 were black (1,014 in the preimplementation period and 933 in the postimplementation period) and 749 were nonblack (370 in the preimplementation period and 379 in the postimplementation period). Regardless of race, women in the postimplementation period had lower rates of SSI compared with those in the preimplementation period (black: 2.9 vs. 5.2%, aOR: 0.53 [95% CI: 0.33-0.85]; nonblack: 1.1 vs. 3.5%, aOR: 0.28 [95% CI: 0.09-0.89]). There was no interaction by race (p for interaction = 0.94). The care bundle decreased SSI in both black and nonblack women but did not reduce racial disparities.

The Role of Bowel Preparation in Colorectal Surgery: Results of the 2012-2015 ACS-NSQIP Data.

To analyze potential benefits with regards to infectious complications with combined use of mechanical bowel preparation (MBP) and ABP in elective colorectal resections. Despite recent literature suggesting that MBP does not reduce infection rate, it still is commonly used. The use of oral antibiotic bowel preparation (ABP) has been practiced for decades but its use is also controversial. Patients undergoing elective colorectal resection in the 2012 to 2015 American College of Surgeons National Surgical Quality Improvement Program cohorts were selected. Doubly robust propensity score-adjusted multivariable regression was conducted for infectious and other postoperative complications. A total of 27,804 subjects were analyzed; 5471 (23.46%) received no preparation, 7617 (32.67%) received MBP only, 1374 (5.89%) received ABP only, and 8855 (37.98%) received both preparations. Compared to patients receiving no preparation, those receiving dual preparation had less surgical site infection (SSI) [odds ratio (OR) = 0.39, P < 0.001], organ space infection (OR = 0.56, P ≤ 0.001), wound dehiscence (OR = 0.43, P = 0.001), and anastomotic leak (OR = 0.53, P < 0.001). ABP alone compared to no prep resulted in significantly lower rates of surgical site infection (OR = 0.63, P = 0.001), organ space infection (OR = 0.59, P = 0.005), anastomotic leak (OR = 0.53, P = 0.002). MBP showed no significant benefit to infectious complications when used as monotherapy. Combined MBP/ABP results in significantly lower rates of SSI, organ space infection, wound dehiscence, and anastomotic leak than no preparation and a lower rate of SSI than ABP alone. Combined bowel preparation significantly reduces the rates of infectious complications in colon and rectal procedures without increased risk of Clostridium difficile infection. For patients undergoing elective colon or rectal resection we recommend bowel preparation with both mechanical agents and oral antibiotics whenever feasible.

Implementation of an evidence-based practice to decrease surgical site infection after coronary artery bypass grafting.

ObjectiveSurgical site infection (SSI) is a serious complication after coronary artery bypass grafting (CABG). This study was performed to evaluate evidence-based practice and structured problem-solving to reduce SSI after CABG.MethodsAn infection control strategy including supervised chlorhexidine gluconate (CHG) showers was implemented from January 2017 to March 2018 for 119 patients undergoing CABG. The controls comprised 244 patients who underwent CABG from 2014 to 2016. Risk factors for SSI were identified, and a problem-focused strategy was used to control SSI. Propensity score matching was used to study the effect of CHG showers on SSI.ResultsSSI occurred in 25 patients (10.25%) in the control group, and the significant risk factors were the postoperative blood glucose level, transfer from an outside hospital, emergency operation, redo sternotomy, a higher American Society of Anesthesiologists score, and the duration of surgery. After implementation of the program, the SSI rate significantly decreased to 3.36%. Patients who had undergone preoperative CHG showers had a significantly lower SSI rate (1.69%) than the matched controls (13.56%).ConclusionSSI after CABG can be reduced using evidence-based practice and structured problem-solving to identify risk factors. A preoperative CHG shower is associated with a lower SSI rate after CABG.

Protective effect of intraoperative re-dose of prophylactic antibiotics on surgical site infection in diabetic patients: a retrospective cohort study.

Surgical site infection (SSI) has a high incidence in diabetic surgical patients. Preoperative antibiotic prophylaxis followed by an intraoperative re-dose was a common strategy in diabetic prolonged procedures. However, there were lacking studies on the relative benefits of this strategy on SSI. Our study aimed to clarify the effect of intraoperative re-dose of prophylactic antibiotics on SSI in diabetic patients. A total of 1,840 diabetic patients with prolonged surgeries were included and Cefazolin was the only type of antibiotic prophylaxis. We assessed the relationship between intraoperative re-dose of cefazolin and 30-day incidence of SSI using a retrospective cohort study method. There were 361 diabetic cases with preoperative antibiotics only and 1,479 cases with pre- plus intraoperative antibiotics, in which 60 subjects suffered from SSI. Pre- plus intraoperative prophylaxis group had a lower rate of SSI in the overall and subgroup analyses when compared with preoperative only group. Operation location, combined with hypertension, poor blood glucose control, high WBC count and ASA score >2 were significantly associated with an increased risk of SSI for diabetic surgical patients (all P<0.05). Intraoperative re-dose of prophylactic antibiotics was statistically related to a lower incidence rate of SSI than preoperative prophylaxis alone (crude RR =0.47; 95% CI, 0.27-0.82; P<0.01), while the association remained significant even after adjusting the potential confounders (adjusted RR =0.51; 95% CI, 0.29-0.90; P=0.02). For diabetic patients, intraoperative re-dose of prophylactic antibiotics may be an independent protective factor for the prevention of SSI. A specific perioperative antibiotics injection strategy should be encouraged for diabetic patients with prolonged surgeries to minimize the possibility of SSI.

Surgical Site Infection in Endometriosis Surgery Is a Rare Complication: Results of a Single Center's Prospective Surveillance of Eight Hundred Ninety-Six Procedures.

Background: There are no studies reporting the rate of surgical site infection (SSI) after surgery for endometriosis, although this information is valuable when discussing the most appropriate treatment strategy with the patient. Methods: We conducted a prospective cohort study in a university hospital and regional reference center for endometriosis. We sought to measure the rate of SSI after endometriosis surgery using prospective SSI post-discharge surveillance data and the hospital information system via an ad hoc algorithm using both diagnosis and procedure code classifications. Results: Among 896 consecutive endometriosis surgical procedures, we identified 365 procedures with involvement of the gastrointestinal tract, defined as the deep invasive procedure (DIP) group, 107 procedures with involvement of an ovary, and 424 other procedures. Twelve SSI (all organ/space infections) were observed, all in the DIP group, corresponding to an overall SSI incidence of 1.3% 95% confidence interval (CI) 0.7-2.3, and an SSI incidence in the DIP group of 2.8%, 95% CI 1.5-4.9. The median delay between the procedure and the SSI was 6.5 days (range, 3-23). At least one micro-organism was found in 10 patients (four Escherichia coli, four Enterobacter cloacae, three Enteroccus faecalis, two Bacteroides fragilis, one Pseudomonas aeruginosa, one Candida albicans). Conclusion: A low overall rate of SSI after surgery for endometriosis was observed. Nevertheless, procedures with involvement of the intestinal tract were at risk of SSI.

Evaluating the Impact of Technique and Mesh Type in Complicated Ventral Hernia Repair: A Prospective Randomized Multicenter Controlled Trial

To our knowledge, there is an absence of prospective randomized multicenter controlled trials evaluating both the impact of technique and mesh type on outcomes in complicated ventral hernia repair. A prospective randomized multicenter controlled trial of 120 patients at 3 sites was conducted in which patients were randomized to either overlay (anterior component separation) or underlay mesh placement (posterior component separation) and mesh type (human acellular dermis [HADM] vs porcine acellular dermis [PADM]). Key inclusion criteria included hernia size (>200 cm2), BMI < 40 kg/m2, hemoglobin A1C < 7%, tobacco free > 6 weeks and primary fascial closure. Primary outcome was hernia recurrence at 1 year, determined by independent examiner/imaging. Secondary outcomes included complications and patient satisfaction (short form [SF]-36v2). Standardized investigator training included a porcine model followed by a proctored first case by the lead investigator. There were no significant differences in demographics between the 4 groups (age 60 ±12 years, BMI 32 ± 5 kg/m2, 51% female). The overall 1-year recurrence rate was 10.8%. There was no significant difference in recurrence rate by location of mesh placement (overlay 9.8%, underlay 11.9%) or mesh type (HADM 10.3%, PADM 11.3%). Overlay patients had a significantly lower surgical site infection rate (1.6% vs 11.9% p= 0.03), reported better physical functioning (p= 0.001) and role limitation scores (p= 0.04) in the early postoperative period, and achieved the highest physical functioning score during the 12-month period (p < 0.03). Recurrence rates were not affected by either anatomic location or type of mesh used. To our knowledge, this represents the first prospective randomized multicenter controlled trial that demonstrates similar clinical outcomes using HADM vs PADM (not inferiority, contrary to previously published literature), with several advantages identified using the overlay technique.

A Systematic Review on the Urinary Tract Infections in Patients Submitted to Bariatric Surgery

Introduction: Urinary tract infections (UTI) are common, accounting for 40% of all hospital infections and affecting about 1.7 million patients annually. Previous studies have shown that up to 80% of UTI are associated with catheters. Still, UTI represent 16.9% of all post-discharge complications in BS patients. Objective: To analyze the incidence of urinary tract infections in patients undergoing BS, as well as whether any patient received prophylactic antibiotics and whether this measure was effective in preventing infections. It has been hypothesized that review procedures are significantly associated with increased UTI rate after BS. Methods: Following literary search criteria with the use of the MeSH Terms that were cited in the item on Search strategies, a total of 34 clinical studies that were submitted for eligibility analysis were checked, and after that, 26 studies were selected, following the rules of systematic review-PRISMA. Results and conclusion: Because E. coli is a gram-negative bacterium and is the most common cause of urinary tract infections, clindamycin monotherapy can leave patients susceptible to gram-negative organisms. American and European guidelines recommend cefazolin prophylaxis. The care package structured by basic evidence-based strategies was able to maintain low surgical site infection rates after BS. BS before elective posterior lumbar fusion reduces the risk of medical complications and infection. It was found that the risk of soft tissue infection and respiratory infection decreased after BS, while the risk of intra-abdominal infection and UTI increased.

Surgical site infection in bariatric surgery: results of a care bundle.

to present a descriptive analysis of the results of a care bundle applied to obese patients submitted to bariatric surgery, regarding infection control. a care bundle was designed to control surgical site infection (SSI) rates in patients undergoing bariatric surgery. The bundle included smoking cessation, bathing with 4% chlorhexidine two hours before surgery, cefazolin (2g bolus) in anesthetic induction associated with a continuous infusion of the same drug at a dose of 1g over a two-hour period, appropriate trichotomy, glycemic control, supplemental oxygen, normothermia, intraspinal morphine for the relief of pain, and sterile dressing removal 48 hours after surgery. All patients were followed up for 30 days. among the 1,596 included patients, 334 (20.9%) underwent open surgery and 1,262 (79.1%) underwent videolaparoscopic surgery. SSI rates were 0.5% in the group submitted to laparoscopic surgery and 3% in the one submitted to open surgery. The overall incidence of SSI was 1%. Intra-abdominal, respiratory tract, and urinary tract infections occurred in 0.9%, 1.1%, and 1.5% of the sample, respectively. Higher body mass index was associated with higher incidence of SSI (p=0.001). Among patients with diabetes, 2.2% developed SSI, while the rate of infection among non-diabetics was only 0.6%. the established care bundle, structured by core evidence-based strategies, associated with secondary measures, was able to maintain low SSI rates after bariatric surgery.
