The presence of carbapenemase-producing carbapenem-resistant Enterobacterales (CP-CRE) around the world is increasing, particularly in healthcare settings. Surveillance testing for plasmid-mediated carbapenemase genes is necessary to tracking CP-CRE infections. In the state of Ohio, surveillance of carbapenem-resistant Enterobacterales (CRE) began in 2018, and to the authors' knowledge data on these cases has not been published to date. This study analyzed data on CRE from a large teaching hospital in Ohio, and by the Ohio Department of Health Laboratory (ODHL). Carbapenemase production was detected using mCIM, and plasmid-mediated carbapenemase genes were detected using rtPCR. Data was collected on 344 standard-of-care isolates from a large teaching hospital in Ohio, including data collected from chart review. Deidentified surveillance data on 4,391 CRE isolates was provided by the ODHL. Statistical analysis was performed using binary logistic regression. While KPC was the most common carbapenemase gene (n=1590), NDM (n=98), VIM (n=10), IMP (n=39) and OXA-48 (n=35) were also detected in the isolates studied. Klebsiella pneumoniae and Enterobacter cloacae were the most common CRE, and carbapenemase genes were most commonly detected in K. pneumoniae. Inpatient hospital stays and long-term care were associated with CP-CRE and were more common in women. Surveillance data shows that CP-CRE are present in Ohio, most commonly in Klebsiella pneumoniae. A better understanding of the prevalence of CRE, plasmid-mediated carbapenemase genes present, and the populations affected are important when tracking the spread of disease. Further study and surveillance of carbapenem-resistant organisms can provide a better understanding of their prevalence in the state.

In sub-Saharan Africa, the provision of infection prevention and control (IPC) measures are often limited by resource constraints. To determine the association of supportive supervision activities with the availability of the WHO core components for IPC at health facilities in Southwestern Uganda. We employed a before and after quality improvement study design. We conducted a baseline assessment of the availability of the WHO IPC core components and provided supportive supervision activities, which was followed by a second IPC assessment. We included health centers II-IV, which have increasing clinical care capacity, and regional hospitals. Of 244 regional health facilities, baseline assessment occurred at 111 (45%) of which 23 (21%) were reassessed. The number of facilities in the Red (85%) for instrument processing. There was an increase in the median (interquartile range [IQR]) overall score for all facilities (65 [54-72] vs 75 [68-83], p=0.0001). Supportive supervision activities were associated with improved availability of the core components of IPC at health facilities in Southwestern Uganda. PPE should be prioritized in health care facilities in Southwestern Uganda.

Обзор, doi.org, Abstract
Klebsiella pneumoniae is among the World Health Organization's list of priority pathogens, notorious for its role in causing healthcare-associated infections and neonatal sepsis globally. Containment of K. pneumoniae transmission depends on the continued effectiveness of antimicrobials and of biocides used for topical antisepsis and surface disinfection. Klebsiella pneumoniae is known to disseminate antimicrobial resistance (AMR) through a large auxiliary genome made up of plasmids, transposons and integrons, enabling it to evade antimicrobial killing through the use of efflux systems and biofilm development. Because AMR mechanisms are also known to impart tolerance to biocides, AMR is frequently linked with biocide resistance (BR). However, despite extensive research on AMR, there is a gap in knowledge about BR and the extent to which AMR and BR mechanisms overlap remains debatable. The aim of this paper is to review and summarise the current knowledge on the determinants of BR in K. pneumoniae and highlight content areas that require further inquiry.

A direct observational pilot project of healthcare personnel (HCP) was conducted to validate a tool that measures personal protective equipment (PPE) adherence at a large pediatric institution. Overall unit PPE adherence for all moments ranged from 50-61%. Masking was the most adhered to PPE moment (100%); hand hygiene prior to donning PPE had the lowest adherence (13%). Using data from this standardized tool, researchers can evolve PPE standards to maximize their adherence, effectiveness, and ease of utilization.

This report details how one large medical center in the Metropolitan New York area re-purposed a drive-through COVID-19 vaccination structure to handle a surge in Mpox cases in July 2022. Methods/Results: Simultaneous to on-going COVID -19 vaccination and testing, Mpox vaccination was rolled out in the same drive through structure. More than 1,820 Jynneos (Smallpox and Monkeypox Vaccine, Live, Non-replicating) vaccine dosages were delivered subcutaneously and then intradermally to 1,123 individuals through the open window of their vehicles, averaging 8-10 patients an hour. Five vaccine recipients suffered Mpox rash; there was no exposure among healthcare providers. Drive-through vaccination is an efficient model to be redeployed for future unexpected vaccine initiatives.

Acquisition of carbapenemase-producing carbapenem-resistant Enterobacterales (CP-CRE) are associated with negative health outcomes. Our adult intensive care unit (ICU) population has experienced low levels of CP-CRE acquisition; however, specific risk factors for this population at our medical facility have not been studied. To identify risk factors of CP-CRE acquisition and describe CP-CRE epidemiology among adult ICU patients at our medical facility. A retrospective cohort study was performed at a Kentucky Academic Medical Center. Surveillance specimens were collected at admission and weekly thereafter to identify CP-CRE colonization. Clinical data were extracted from patient medical records. Cases were defined as those who tested positive for CP-CRE on ICU admission day 3 or greater. Risk of CP-CRE acquisition was calculated using Modified Poisson regression. Independent risk factors of CP-CRE acquisition included administration of enteral tube feeds (risk ratio [RR], 4.46; 95% confidence interval [CI], 1.74-11.43); diagnosis of Clostridioides difficile enterocolitis (RR, 3.51; 95% CI, 1.27-9.68), pressure ulcer (RR, 3.48; 95% CI, 1.91-6.36), and morbid obesity (RR, 2.10; 95% CI, 1.12-3.95); having a drainage tube (RR, 2.63; 95% CI, 1.38-4.98); admission to a medical ICU (RR, 2.39; 95% CI, 1.32-4.35); 90-day use of a carbapenem (RR, 2.27; 95% CI, 1.21-4.26); and dialysis procedure (RR, 2.22; 95% CI, 1.15-4.27). Most CP-CRE risk factors were associated with alteration of colon microbiota and/or invasive procedures/devices. These results will assist in creating a more targeted CP-CRE active surveillance system and highlight areas for infection prevention intervention.

Hand hygiene is critical to lower the potential for the spread of SARS-CoV-2 and other infectious agents by direct contact. When running water and soap are not available for hand hygiene, ethanol-based hand sanitizers are currently the recommended standard of care [[1], [2], [3]]. Though recently published data showed comparable in vitro effectiveness of benzalkonium chloride (BAK)-based and ethanol-based hand sanitizers against SARS-CoV-2 virus, a paucity of peer-reviewed data on the effectiveness of these formulations against other types of infective coronaviruses remains. This work assessed human coronavirus HCoV-229E (genus Alphacoronavirus) concurrently with SARS-CoV-2, Isolate USA-WA1/2020 (genus Betacoronavirus) to fill this gap. The test was conducted according to EN14476:2013-A2:2019 [EN14476] Quantitative Suspension Test for the Evaluation of Virucidal Activity in the Medical Area [4]. Two BAK-based hand sanitizers, five ethanol-based hand sanitizers, and an 80% ethanol reference formulation were tested for antiviral activity against SARS-CoV-2 and HCoV-229E at 15- and 30- second contact times. Both SARS-CoV-2 and HCoV-229E were reduced by greater than 4.00-log10 within 15 seconds of contact. Virus decay constants (k) following first-order kinetics were similar for BAK and ethanol-based formulations against both test viruses. The SARS-CoV-2 results reported herein mirrored previous data reported by Herdt et al. (2021). BAK and ethanol hand sanitizer formulations inactivate SARS-CoV-2 and HCoV-229E at similar rates. This data supports previously published effectiveness data for both chemistries and indicates that additional coronavirus strains and variants would demonstrate similar inactivation trends.

Cloth privacy curtains represent a potentially overlooked high touch surface. Inconsistent cleaning schedules paired with frequent contact allow curtains to provide a surface for the transmission of healthcare associated pathogens. Privacy curtains integrated with antimicrobial and sporicidal agents are shown to reduce the number of bacteria found on the surface of the curtains. The purpose of this initiative is to utilize antimicrobial and sporicidal privacy curtains to mitigate the transmission of healthcare associated pathogens from curtains to patients. The pre/post-test study design compared the bacterial and sporicidal burden of cloth curtains to the bacterial and sporicidal burden of Endurocide curtains following 20-weeks of use within the inpatient setting of a large military medical hospital. The Endurocide curtains were installed on two inpatient units in the organization. We also compared the overall costs associated with the two different types of curtains. The antimicrobial and sporicidal curtains had a significant reduction in bacterial contamination (32.6 CFUs vs 0.56 CFUs, P < 0.05) after instillation on both units. There were no additional hospital associated infections during the study period. In addition, the direct cost savings of replacing the antimicrobial and sporicidal curtains is estimated to be $20,079.38 annually with a reduction of 66.95 hours in environmental services workload. These curtains represent a cost-effective intervention effective at reducing CFUs with the potential to mitigate the transmission of hospital associated pathogens to patients.

In operating room (OR) surfaces, Nosocomial pathogens can persist on inanimate surfaces for long intervals and are highly resistant to traditional surface cleaning.This study compares traditional chemical operating room terminal disinfection to a unique operator-driven device that emits germicidal UV light at short distance onto vertical and horizontal surfaces.A randomized crossover analogous protocol assigned 40 end-of-day operating rooms into either group A (chemical then UVC treatments) or group B (UVC then chemical treatments). Initial Staphylococcal cultures were obtained prior to disinfection treatment, after the first treatment, and after the second treatment at 16 most commonly contaminated sites to represent overall room contamination. Success was defined as no growth and failure as 1 or more colony forming units. Thoroughness of chemical treatment vs UVC treatment was compared and used to determine if the second treatment was additive to the first treatment within each group.The operator driven UVC device outperformed chemical treatment in reducing the number of contaminated sites in the OR by more than half (P

Surgical site infection prevention and treatment remains a challenge in healthcare settings globally. The routine use of intranasal mupirocin for decolonization has challenges and preoperative intranasal povidone-iodine decolonization is another option. The purpose of this quality improvement study was to assess if a one-time preoperative intranasal povidone-iodine application could reduce the risk of the likelihood of nasal carriage of Staphylococcus aureus after surgery.Ambulatory Surgery Center patients were enrolled in an intranasal povidone-iodine decolonization quality improvement study as they reported at the pre-operative holding area. Pre-decolonization intranasal samples were collected, followed by intranasal application of povidone-iodine. Patients waited for a minimum of 20 minutes after application before proceeding with surgery. Nasal samples were again collected after surgery. Each sample was tested for S. aureus colonization using the 16S rRNA-mecA-nuc triplex polymerase chain reaction, standard biochemical tests, and qualitative culturing.In the 98 patients enrolled, 36% of these patients had intranasal colonization with S. aureus by 16S rRNA-mecA-nuc triplex polymerase chain reaction before surgery. Using a qualitative culture technique, 28% of patients tested positive for S. aureus before surgery and 20% of patients tested positive for S. aureus after surgery (P = 0.039).Intranasal preoperative povidone-iodine is an effective strategy in the decolonization of S. aureus from the nares if properly implemented.

To maintain a low incidence of Catheter Related Infections (CRI) and Catheter Related Bloodstream Infections (CRBSI), continuous follow-up studies on catheter management are necessary. The aims of the present study were to investigate the incidence of catheter tip colonisation, CRI and CRBSI in the Region, to further explore the feasibility of automatic data collection and to investigate associations between independent variables and CRI. Data from electronic patient charts on all documented central venous catheter (CVC) insertions from multiple hospitals in southern Sweden, between March 2019 and August 2020, were automatically extracted. Multivariable regression analyses were used to identify associated risk factors. In total, 9924 CVC insertions were included. The prevalence of CRI and CRBSI were 0.7% (n = 74) and 0.02% (n = 20) with incidences of 1.2/1000 catheter days and 0.3/1000 catheter days, respectively. We found a sustained low incidence of CRI and CRBSI in the Region. Catheter tips were less likely to be colonised when the subclavian route was used compared to the internal jugular route and male sex as well as increased number of catheter lumens were associated with both catheter tip colonisation and CRI. By using automated scripts, data extraction was efficient and feasible but also demonstrated that real-time quality assurance should be recommended, since this is superior to current standard.

Personal protective equipment (PPE) is effective in preventing coronavirus disease (COVID-19) infection. Resident knowledge of proper use and effective training methods is unknown. We hypothesise that contamination decreases and knowledge increases after a formalised PPE educational session.Participants included first year interns during their residency orientation in June 2020. Before training, participants took a knowledge test, donned PPE, performed a simulated resuscitation, and doffed. A standardised simulation-based PPE training of the donning and doffing protocol was conducted, and the process repeated. Topical non-toxic highlighter tracing fluid was applied to manikins prior to each simulation. After doffing, areas of contamination, defined as discrete fluorescent areas on participants' body, was evaluated by ultraviolet light. Donning and doffing were video recorded and asynchronously rated by two emergency medicine (EM) physicians using a modified Centers for Disease Control and Prevention (CDC) protocol. The primary outcome was PPE training effectiveness defined by contamination and adherence to CDC sequence.Forty-eight residents participated: 24 internal medicine, 12 general surgery, 6 EM, 3 neurology, and 3 psychiatry. Before training, 81% of residents were contaminated after doffing; 17% were contaminated after training (P

Infections with carbapenem-resistant Enterobacterales (CRE) are associated with increased risk of death. Polymicrobial infections with antimicrobial-resistance may add to the burden of clinical care and patients' clinical prognosis. To examine the impact of CRE co-infection with other multi-drug resistant organisms (MDRO) on patient clinical outcomes. A retrospective observational study was conducted to compare the clinical outcomes of CRE patients who were co-infected with carbapenem-resistant Pseudomonas aeruginosa (CRPA), multidrug-resistant Acinetobacter baumannii (MDRA) and Methicillin-resistant Staphylococcus aureus (MRSA). A total of 224 CRPA and 209 MDRA co-infections with CRE were identified from 4,236 cases from 2015-2020. The overall 90-day all-cause mortality was 21.6% but increased to 35.0% and 33.5% among patients who were co-infected with CRPA and MDRA, respectively. The odds of all-cause mortality among CRE patients who were co-infected with CRPA was twice that of patients identified with CRE alone [adjusted odds ratio (AOR) = 2.02, 95% confidence interval (CI): 1.18–3.46]. Further, the odds of all-cause mortality among CRE patients who were concomitantly identified with MRSA was more than twice that of patients who were not identified with MRSA [AOR = 2.16, 95%CI:1.31–3.56]. The clinical outcome of patients with CRE did not differ significantly depending on the presence of carbapenemase genes. The results show that CRPA and CRE co-infections have synergistic effects on clinical outcomes. Further investigation is necessary to understand the mechanism. Screening high risk patients for concomitant antimicrobial-resistant infections may have a significant clinical impact, including effective therapies, antibiotic stewardship, and infection control policies.

The World Health Organization recommends monitoring alcohol-based handrub (ABHR) consumption and direct observation of hand hygiene practices to ensure compliance. In Japan monitoring of ABHR consumption is widely performed. However, direct observation is not common, particularly in small facilities and non-acute-care facilities. Hence, the current study aimed to evaluate the longitudinal effects of direct observation of hand hygiene practices and monitoring of ABHR consumption with provision of feedback to healthcare personnel on ABHR consumption and hand hygiene compliance.We conducted a 4-year prospective intervention study. Monitoring of ABHR consumption and direct observation of hand hygiene practices with monthly feedback to healthcare personnel was implemented in 17 facilities. These consisted of 11 acute-care facilities of varying sizes and six non-acute-care facilities. A generalized linear mixed model analysis was performed to assess factors associated with ABHR consumption.All facilities implemented ABHR consumption monitoring within one month of starting the study. However, the mean time required to implement direct observation of hand hygiene practices was 24.7 (±19.1) months. The ABHR consumption increased significantly (P

Reduced vancomycin susceptibility in Staphylococcus aureus (S. aureus) is considered a more pathogenic strain characteristic and is associated with treatment failure. We aimed to characterise the epidemiology of intraoperative transmission of S. aureus isolates with reduced vancomycin susceptibility. S. aureus isolates (N=173) collected from 274 randomly selected operating room environments at three major academic medical centres in 2009–2010 were characterised by vancomycin minimum inhibitory concentration (MIC). We aimed to characterise the transmission dynamics for VISA and isolates with relatively reduced vancomycin (MIC= 2μg/mL) susceptibility at the range of therapeutic differentiation. Intraoperative S. aureus MIC was 1.38 ± 0.34 μg/mL. No VISA isolates were identified (95% upper confidence limit 2.1%) and those with an MIC of 2 μg/mL accounted for 12.72% (22/173) of all isolates. MIC=2 μg/mL isolates were more frequently cultured from the hands of healthcare providers [19.3% (16/83)] versus otherwise [6.7% (6/90)], with unadjusted risk ratio 2.89, P=0.021, and from patients with >2 major comorbidities [25.0% (8/32)] versus otherwise [9.9% (14/141)], with unadjusted risk ratio 2.52, P=0.035. Both were significant when tested simultaneously. The adjusted relative risk for provider hands was 2.77 (95% CI 1.15 to 6.69, P=0.024). The adjusted relative risk for patients with >2 major comorbidities was 2.37 (95% CI 1.11 to 5.05, P=0.026). MIC=2μg/mL was not associated with greater risk of clonal transmission (unadjusted P=0.34, adjusted P=0.18). Intraoperative VISA is a rare event. S. aureus isolates MIC=2μg/mL isolates were not associated with increased risk of intraoperative transmission. The epidemiology of detected intraoperative transmission is consistent with Centers for Disease Control guidelines.

Airborne bacteria present in the operating room may be a cause of surgical site infection, either contaminating the surgical wound directly, or indirectly via e.g. surgical instruments. The aim of this study was to evaluate if instrument and assistant tables equipped with local unidirectional airflow reduce bacterial contamination of the instrument area to ultra clean levels, during orthopedic implant surgery in an operating room with displacement ventilation. Local airflow units of instrument and assistant tables were either active or inactive. Colony forming units were sampled intraoperatively from the air above the instruments and from instrument dummies. A minimum of three air samples and two-three samples from instrument dummies were taken during each surgery. Samples were incubated on agar for total aerobic bacterial count. The mean air and instrument contamination during each surgery was calculated and used to analyze the difference in contamination depending on use of local airflow or not. All procedures were performed in the same OR. 188 air and 124 instrument samples were collected during 48 orthopedic implant procedures. Analysis showed that local unidirectional airflow above the surgical instruments significantly reduced the bacterial count in the air above assistant table ( P

Healthcare-associated infections (HAIs) affect patient health. Patients with Paediatric Intensive Care Unit (PICU) acquired viral respiratory infections had longer use of respiratory support. We found it's uncommon in ICUs to have high risk HAIs. RSV, parainfluenza, and hMPV are the most common, and 1/3 of patients required escalation in respiratory support and/or escalation in antibiotics. All patients had underlying comorbidities. In our series there were two deaths within 2 weeks of infection.

Blood culture contamination poses an issue to all hospital systems worldwide because of the associated costs of extended length of stays, unnecessary antibiotic therapy, and additional laboratory testing that are preventable with proper handling and collection techniques. In our study, multiple units, staff, and collection methods were compared to determine the primary culprits of contamination from a tertiary care academic medical center, which includes a pediatric hospital and both adult and pediatric emergency departments. Over 33 months, 2,083 out of 88,322 total blood cultures collected were contaminated, with an overall contamination rate of 2.4%. A moderate positive correlation was found between the monthly total number of cultures and monthly contamination rate ( r = 0.411 P < .01). The most notable factors associated with contamination were found to be phlebotomy teams (2.7%) ( P < .01), peripheral draws (2.3%) ( P

We aimed at identifying factors associated with documented MRSA transmissions.Single center, retrospective, nested case-control study. We evaluated the screening strategy in our 950 bed tertiary care hospital from 2008 - 2014. Room and ward contacts of MRSA index patients present at time of MRSA identification were screened. We compared characteristics of Staphylococcus aureus Protein A (spa)-type matched contact patients (cases) to negative or spa-type mismatched contact patients (controls).Among 270,000 inpatients from 2008 - 2014, 215 MRSA screenings yielded 3013 contact patients, and 6 (0.2%) spa-type matched pairs. We included 225 controls for the nested case-control study. The contact type for the cases was more frequently "same room" and less frequently "same ward" compared with the controls (P = 0.001). Also, exposure time was longer for cases (median of 6 days [IQR 3-9]) than for controls (1 day [0-3], P=0.016).The extensive MRSA screening strategy revealed only few index/contact matches based on spa-typing. Prolonged exposure time and a shared room were significantly associated with MRSA transmission. A targeted screening strategy may be more useful in a low prevalence setting than screening entire wards.

Infection prevention and control (IPC) practices are required to prevent nosocomial infection by severe acute respiratory syndrome coronavirus 2. In low- and middle-income countries, where resources are often limited, IPC practices are infrequently assessed.To assess the availability of the core components of World Health Organization (WHO) IPC practices at health facilities in Southwestern Uganda.We assessed the availability of WHO IPC core components using a modified WHO IPC Assessment tool. We determined differences between government versus private ownership and by type of health facility.We assessed 111 of 224 (50%) health facilities in four districts. The most frequently achieved core component of IPC strategies was environmental cleanliness with 75 of 111 (68%) facilities scoring >85%. The most infrequently achieved core component of IPC strategies was personal protective equipment (PPE) with only one of seven (14%) hospitals and no other facilities scoring >85%. Of the 20 hospital or health center IV facilities, five (25%) received an overall score of >85% compared to only one of 91 (1%) health center II or III facilities (odds ratio [OR] 30.0 [95% CI: 3.27-274.99], p=0.003). Of the 73 government facilities, two (3%) received an overall score of >85% compared to five of 38 (13%) private facilities (OR 0.24 [95% CI: 0.04-1.37], p=0.11).Few facilities in four districts in Southwestern Uganda achieved >85% availability of WHO IPC core components. Provision of PPE in these facilities should be prioritized.
