Abstract Background Although several meta-analyses reported the impact of chlorhexidine (CHX) use in patients undergoing various types of surgery, no meta-analysis summarized the overall effectiveness of CHX specifically for cardiac surgery. This meta-analysis aimed to examine the impact of CHX on infections after cardiac surgery compared with other cleansers or antiseptics. Methods PubMed, Embase, and the Cochrane Library were searched from inception up to October 2020 for potentially eligible studies: (1) population: patients who underwent cardiac surgery; (2) intervention or exposure: any type of CHX use in the treatment or exposed group; (3) outcome: number of patients with infections; (4) comparison: placebo or other antiseptic agents; (5) English. The primary outcome was surgical site infection (SSI). Results Fourteen studies were included, with 8235 and 6901 patients in the CHX and control groups. CHX was not protective against SSI (OR = 0.77, 95% CI: 0.57–1.04, P = 0.090). CHX was protective for superficial wound infection (OR = 0.42, 95% CI: 0.26–0.70, P = 0.001), but not with deep wound infection (P = 0.509). CHX was not protective against urinary tract of infection (P = 0.415) but was protective for bloodstream infection (OR = 0.36, 95% CI: 0.16–0.80, P = 0.012), nosocomial infections (OR = 0.55, 95% CI: 0.44–0.69, P < 0.001), and pneumonia (OR = 0.26, 95% CI: 0.11–0.61, P = 0.002). Conclusions In patients undergoing cardiac surgery, CHX does not protect against SSI, deep wound infection, and urinary tract infections but might protect against superficial SSI, bloodstream infection, nosocomial infections, and pneumonia.

The aim of this study was to reduce incidence of sternal deep wound infection (DWI) in patients following cardiac surgery. An experience of cardiac surgery by sternotomy access in 429 consecutive patients was presented. Perioperative intravenous injections of cefazolin were used in 225 patients (control group). Combination of perioperative intravenous injections with local retrosternal irrigation of cefazolin before sternum closure was used in 204 patients (study group). In control group sternal DWI occurred in 10 patients (4.4%), and in 4 patients a resternotomy sanation required. There were no deaths in this group due to infection or sepsis. In follow-up period (3 years), instability of sternum occurred in 3 patients (1.3%), and in 1 (0.4%) sternum reosteosynthesis required. In studied group the sternal DWI did not occur (p<0.01). Sternum instability and/or indications for sternum reosteosynthesis were not determined in follow-up period (2 years). It was concluded, that combination of intravenous and local usage of cefazolin in cardiac surgery patients is a simple and effective approach to prevent sternal DWI. Application of this method significantly (p<0.01) reduces the incidence rate of mediastinitis.

Background: The choice of appropriate antibiotics to treat nosocomial infections requires knowledge of antibiotic resistance pattern in the hospitals. The aim of this study was to determine antimicrobial resistance patterns of common pathogens of nosocomial infections (pneumonia, UTI, bloodstream infection, wound infection) in a referral teaching hospital. Methods: This cross-sectional study was conducted over a 6-month period. The pathogens isolated from biological samples of hospitalized patients with nosocomial pneumonia, UTI, bloodstream infection, or wound infection underwent antibiotic susceptibility testing by Kirby-Bauer method (disk diffusion test). Results: Over the study period, 442 cases of infection were recorded. Pneumonia (n = 204, 46.2%) and UTI (n = 118, 26.7%) showed the most frequency followed by BSI (n = 71, 16.1%) and wound infection (n = 49, 11%). Acinetobacter baumannii was the most common pathogen of nosocomial pneumonia infection that showed the most susceptibility to colistin (100%). Escherichia coli, the most common pathogen of urinary tract infections, showed the highest sensitivity to colistin (100%). Staphylococcus epidermidis was the most common bloodstream infection pathogen that showed the most sensitivity to vancomycin (100%). Enterococcus spp., the most common pathogens of wound infection, had the most susceptibility to linezolid (100%). Conclusion: Nosocomial infections in our hospital have high rate of resistance to antibiotics representing the importance of improvement in antibiotic use and infection control.

This study sought to assess the prevalence and impact of biofilms on two commonly biofilm-related infections, bloodstream and urinary tract infections (BSI and UTI). Separated systematic reviews and meta-analyses of observational studies were carried out in PubMed and Web of Sciences databases from January 2005 to May 2020, following PRISMA protocols. Studies were selected according to specific and defined inclusion/exclusion criteria. The obtained outcomes were grouped into biofilm production (BFP) prevalence, BFP in resistant vs. susceptible strains, persistent vs. non-persistent BSI, survivor vs. non-survivor patients with BSI, and catheter-associated UTI (CAUTI) vs. non-CAUTI. Single-arm and two-arm analyses were conducted for data analysis. In vitro BFP in BSI was highly related to resistant strains (odds ratio-OR: 2.68; 95% confidence intervals-CI: 1.60–4.47; p < 0.01), especially for methicillin-resistant Staphylococci. BFP was also highly linked to BSI persistence (OR: 2.65; 95% CI: 1.28–5.48; p < 0.01) and even to mortality (OR: 2.05; 95% CI: 1.53–2.74; p < 0.01). Candida spp. was the microorganism group where the highest associations were observed. Biofilms seem to impact Candida BSI independently from clinical differences, including treatment interventions. Regarding UTI, multi-drug resistant and extended-spectrum β-lactamase-producing strains of Escherichia coli, were linked to a great BFP prevalence (OR: 2.92; 95% CI: 1.30–6.54; p < 0.01 and OR: 2.80; 95% CI: 1.33–5.86; p < 0.01). More in vitro BFP was shown in CAUTI compared to non-CAUTI, but with less statistical confidence (OR: 2.61; 95% CI: 0.67–10.17; p < 0.17). This study highlights that biofilms must be recognized as a BSI and UTI resistance factor as well as a BSI virulence factor.

Abstract Background Automatic antimicrobial stop orders (ASOs) are a stewardship initiative used to decrease days of therapy, prevent resistance, and reduce drug costs. Limited evidence outside of the perioperative setting exists on the effects of ASOs on broad spectrum antimicrobial use, discharge prescription duration, and effects of missed doses. This study aims to evaluate the impact of an ASO policy across a health system of adult academic and community hospitals for treatment of intra-abdominal (IAI) and urinary tract infections (UTI). ASO Outcome Definitions ASO Outcomes Methods This multicenter retrospective cohort study compared patients with IAI and UTI treated before and after implementation of an ASO. Patients over the age of 18 with a diagnosis of UTI or IAI and 48 hours of intravenous (IV) antimicrobial administration were included. Patients unable to achieve IAI source control within 48 hours or those with a concomitant infection were excluded. The primary outcome was the difference in sum length of antimicrobial therapy (LOT). Secondary endpoints include length and days of antimicrobial therapy (DOT) at multiple timepoints, all cause in hospital mortality and readmission, and adverse events such as rates of Clostridioides difficile infection. Outcomes were also evaluated by type of infection, hospital site, and presence of infectious diseases (ID) pharmacist on site. Results This study included 119 patients in the pre-ASO group and 121 patients in the post-ASO group. ASO shortened sum length of therapy (LOT) (12 days vs 11 days respectively; p=0.0364) and sum DOT (15 days vs 12 days respectively; p=0.022). This finding appears to be driven by a decrease in outpatient LOT (p=0.0017) and outpatient DOT (p=0.0034). Conversely, ASO extended empiric IV LOT (p=0.005). All other secondary outcomes were not significant. Ten patients missed doses of antimicrobials due to ASO. Subgroup analyses suggested that one hospital may have influenced outcomes and reduction in LOT was observed primarily in sites without an ID pharmacist on site (p=0.018). Conclusion While implementation of ASO decreases sum length of inpatient and outpatient therapy, it may not influence inpatient length of therapy alone. Moreover, ASOs prolong use of empiric intravenous therapy. Hospitals without an ID pharmacist may benefit most from ASO protocols. Disclosures All Authors: No reported disclosures

Background: Using alternatives to indwelling urinary catheters plays a vital role in reducing catheter-associated urinary tract infections (CAUTIs). We assessed the impact of introducing female external catheters on urinary catheter utilization and CAUTIs. Methods: In a 500-bed academic medical center, female external catheters were implemented on October 1, 2017, with use encouraged for eligible females with urinary incontinence but not meeting other standard indications for urinary catheters. Nurses were educated and trained on female external catheter application and maintenance, and infection prevention staff performed surveillance case reviews with nursing and medical staff. We determined the number of catheter days for both devices based on nursing documentation of device insertion or application, maintenance, and removal. We used the CAUTI and DUR (device utilization ratio) definitions from the CDC NHSN. Our primary outcomes were changes in DUR for both devices 21 months before and 24 months after the intervention in both intensive care units (ICUs) and non-ICU wards. We used a generalized least-squares model to account for temporal autocorrelation and compare the trends before and after the intervention. Our secondary outcome was a reduction in CAUTIs, comparing females to males. Results: In total, there were 346,213 patient days in 35 months. The mean rate of patient days per month increased from 7,436.4 to 7,601.9 after the implementation of female external catheters, with higher catheter days for both urinary catheters (18,040 vs 19,625) and female external catheters (22 vs 12,675). After the intervention, the DUR for female external catheters increased (0 vs 0.07; P < .001) and for urinary catheters the DUR decreased (0.12 vs 0.10; P < .001) (Fig. 1). A reduction in urinary catheter DUR was observed in ICUs (0.29 vs 0.27; P < .001) but not wards (0.08 vs 0.08; P = NS) (Fig. 2). Of the 39 CAUTIs, there was no significant overall change in the rate per 1,000 catheter days (1.22 vs 0.87; P = .27). In females (n = 20 CAUTI), there was a 61% reduction in the CAUTI rate per 1,000 catheter days (0.78 vs 0.31; P = .02), but no significant change in the rate in males (0.44 vs 0.56; P = .64). The CAUTI rate per 1,000 catheter days among females decreased in the ICUs (1.14 vs 0.31; P = .04) but not in wards (0.6 vs 0.33; P = .96). Conclusions: In a setting with a baseline low UC DUR, successful implementation of female external catheters further modestly reduced UC DUR and was associated with a 61% decrease in CAUTI among females in the ICU but not in wards. Further interventions to better identify appropriate patients for female external catheters may improve patient safety and prevent patient harm.Funding: NoneDisclosures: None

Abstract Background and Study Aims The treatment of infections following a spine surgery continues to be a challenge. Negative pressure wound therapy (NPWT) has been an effective method in the context of infection therapy, and its use has gained popularity in recent decades. This study aims to analyze the impact of known risk factors for postoperative wound infection on the efficiency and length of NPWT therapy until healing. Patients and Methods We analyzed 50 cases of NPWT treatment for deep wound infection after posterior and posteroanterior spinal fusion from March 2010 to July 2014 retrospectively. We included 32 women and 18 men with a mean age of 69 years (range, 36–87 years). Individual risk factors for postoperative infection, such as age, gender, obesity, diabetes, immunosuppression, duration of surgery, intraoperative blood loss, and previous surgeries, as well as type and onset (early vs. late) of the infection were analyzed. We assessed the associations between these risk factors and the number of revisions until wound healing. Results In 42 patients (84%), bacterial pathogens were successfully detected by means of intraoperative swabs and tissue samples during first revision. A total of 19 different pathogens could be identified with a preponderance of Staphylococcus epidermidis (21.4%) and S. aureus (19.0%). Methicillin-resistant S. aureus (MRSA) was recorded in two patients (2.6%). An average of four NPWT revisions was required until the infection was cured. Patients with infections caused by mixed pathogens required a significantly higher number of revisions (5.3 vs. 3.3; p < 0.01) until definitive wound healing. For the risk factors, no significant differences in the number of revisions could be demonstrated when compared with the patients without the respective risk factor. Conclusion NPWT was an effective therapy for the treatment of wound infections after spinal fusion. All patients in the study had their infections successfully cured, and all spinal implants could be retained. The number of revisions was similar to those reported in the published literature. The present study provides insights regarding the effectiveness of NPWT for the treatment of deep wound infection after spinal fusion. Further investigations on the impact of potential risk factors for postoperative wound healing disorders are required. Better knowledge on the impact of specific risk factors will contribute to a higher effectiveness of prophylaxis for postoperative wound infections considering the patient-specific situation.

AbstractA significant unremitting increase in the incidence of nosocomial methicillin-resistant Staphylococcus aureus (MRSA) infections in a 500-bed acute care community teaching hospital prompted reevaluation of the efficacy of the infection control measures used. A well-accepted, low-iodine, antimicrobial soap was used to replace a liquid natural handsoap in two areas with the highest incidence of MRSA—the intensive care unit, and a medical division.Over a two-year period, an analysis was made of the effect of soap replacement on nosocomial infections and pathogens. Soap changeover occurred at the midpoint of the two-year period. From year to year, the nosocomial MRSA rate decreased 80% (t test, P=0.005). Other pathogens that demonstrated a dramatic decrease included methicillin-sensitive Staphylococcus aureus (MSSA), infections where no pathogens were isolated, and various gram-negative infections. Categories of nosocomial infections that decreased included surgical wound infections, primary bacteremias, and respiratory tract infections. The overall nosocomial infection rate of the two combined areas decreased 21.5%, representing a year-to-year savings of $109,500. As a result, the decision was made to install the low-iodine hand-soap permanently at all sinks within the hospital.
