BACKGROUND: Hospitals are exposed to abundant contamination sources with limited remediation strategies. Without new countermeasures or treatments, the risk of hospital-associated infections will remain high. This study explored the impact of advanced photohydrolysis (AP) continuous disinfection technology on hospital environmental bioburden. METHODS: Two acute care Intensive Care Units in different locations (i.e., Kentucky, Louisiana) during different time periods...

BACKGROUND: Medical waste bins are potential source of microbial contamination in hospital environment, while there is no clear guidance for the management of them. We aimed to assess the impact of medical waste bins on patient's environment. METHODS: This experimental study simulated microbial contamination by performing medical procedures on a patient model with fluorescent lotion. The waste bin was set as initially empty or two-thirds filled with waste, open or with a lid...

Experimental evidence suggests that SARS-CoV-2 remains viable within aerosols with a half-life of approximately 3 hours; however, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing during an outbreak suggested in-room transmission of SARS-CoV-2 to two patients admitted nearly 2 and 5 hours, respectively, after discharge of an asymptomatic infected patient. These findings suggest that airborne SARS-CoV-2 may transmit infection for over 4 hours, even in a hospital setting...

BACKGROUND: Hand hygiene (HH) among healthcare workers (HCWs) is crucial in preventing infections in nursing homes. However, HH compliance (HHC) among HCWs remains low. This study aimed to investigate the effect of feedback lights on HCWs' HHC. METHODS: A five-month interventional study was conducted in three wards in a nursing home in [blinded for reviewers]. During the intervention period, a green light with a smiley appeared on the alcohol-based hand rub (ABHR) dispensers when HCWs used the ABHR, acknowledging HCWs for using the ABHR...

BACKGROUND: Repeat departmental-wide surveys are commonly employed for infection-control. There remains debate concerning their cost-effectiveness. AIM OF THE STUDY: To measure the impact of repeat departmental-wide surveys in major in-patient departments (IPD) and ambulatory facilities (AF) in a tertiary care hospital. DESIGN: Retrospective study of 138 surveys conducted in 96 departments over a five-year period. METHODS: Two itemized questionnaires were designed to assess the most frequently inadequately-adhered-to infection control measures: one for IPD (with 21 items), the other for AF (with 17 items)...

The yield of repeat SARS-CoV-2 testing for intrapartum fever in patients admitted to labor and delivery negative for SARS-CoV-2 on admission testing is unknown. From October 2020-June 2022, we performed a retrospective study of 151/3,168 (4.8%) patients who had repeat testing for intrapartum fever. One (0.7%) patient was SARS-CoV-2 positive suggesting repeat SARS-CoV-2 testing for intrapartum fever is generally not warranted nor is separating birthing dyads while awaiting test results.

This population-based study aimed to evaluate the incidence of urinary tract infections (UTIs) following hip and knee arthroplasty (HPRO and KPRO) and to identify UTI risk factors among Polish patients. Analysis included data from 83,525 patients, with incidence rates of 0.7% and 0.49% after HPRO and KPRO, respectively. We identified women, individuals over 65 years old, residents of long-term care facilities, patients with chronic circulatory, endocrine, or digestive diseases, and those operated on due to trauma as targets for infection prevention and control...

INTRODUCTION: Assess how urine chemistry tests are impacted by collection using a female external urinary catheter employing wicking and suction, to assess this catheter's potential as an alternative to transurethral catheters for collecting urine samples from incontinent patients. METHODS: We obtained 50 random 40 mL refrigerated urine specimens from excess volume submitted to the Michigan Medicine Biochemical Laboratory. Specimens were split into a 10 mL "control" sample simulating voided urine, and a 30 mL paired "wicked" sample applied dropwise to and collected from a fresh PureWick system simulating collection from an incontinent patient...

BACKGROUND: Candida auris (C. auris) is a fungal pathogen that has the potential for environmental persistence leading to outbreaks in healthcare settings. There has been a worldwide surge in C. auris outbreaks during the COVID-19 pandemic. In this report, we describe an outbreak of C. auris, its control, patient outcomes, and lessons learned. METHODS: The outbreak occurred in a 600-bed adult academic tertiary care hospital. Contact tracing was initiated immediately after identification of the index case and surveillance testing for C...

BACKGROUND: Surgical site infection (SSI) is a frequent health care-associated infection. We aimed to reduce SSI risk after joint arthroplasty and spine surgery by reducing Staphylococcus aureus colonization burden with presurgery intranasal povidone-iodine (PVP-I) application in conjunction with skin antisepsis ("the intervention"). METHODS: Retrospective case-control study; postintervention cohort versus a historical cohort. Adults who underwent joint arthroplasty or spine surgery during February 2018 through October 2021 ("post-intervention cohort") included...

BACKGROUND: This study describes an outbreak caused by multispecies carbapenemase-producing Enterobacterales (CPE) occurring in a pediatric ward at an academic medical center in Tokyo. METHODS: The index case involved a 1-year-old boy with Klebsiella variicola (CPE) detected in anal swabs in June 2016. The second case was Klebsiella quasipneumoniae (CPE) occurred in March 2017 followed by further spread, leading to the declaration of an outbreak in April 2017. Extensive environmental and patient microbiological sampling was performed...

BACKGROUND: Urinary tract infections (UTI) can lead to neonatal complications like sepsis, worsened by empirical treatment, contributing to antimicrobial resistance (AMR). This study examined the incidence, etiology, risk factors, and antimicrobial susceptibility of uropathogens in a Neonatal Intensive Care Unit (NICU) in Brazil. METHODS: Medical records of neonates hospitalized in the NICU from January 2015 to June 2022 were retrospectively analyzed through the National Healthcare Safety Network system...

BACKGROUND: During the COVID-19 pandemic, with many nurses being infected, understanding compliance with standard precautions (SP) among nurses in Kazakhstan is crucial for improving infection prevention and control and preparedness for future emergencies. The study aimed to assess Kazakh nurses' SP compliance amid the COVID-19 pandemic and examine the factors associated with their compliance. METHOD: Quantitative, cross-sectional design. This research surveyed 241 clinical nurses in Astana, Kazakhstan using a standardized tool from December 2021 to April 2022...

In-refrigerator water dispensing systems are ubiquitous in residential homes with tap water as the inflow. Passage through these systems resulted in significant microbial growth in the water, with the abundance of potential opportunistic pathogens Mycobacterium and Pseudomonas increasing by 8,053- and 221-fold, respectively. Elevated exposure to microbial contaminants linked to in-refrigerator water dispensing systems may represent a significant public health concern.

BACKGROUND: To evaluate the economic loss of hospital acquired infections (HAIs) among tumor patients so as to help policy makers to allocate healthcare resources and address the issue. METHODS: We conducted a retrospective, 1:1 matched case-control study in a large region cancer hospital between Jan 1 and Dec 31, 2022. The economic burden was estimated as the median of the 1:1 pair differences of various hospitalization fees and hospital length of stay (LOS). RESULTS: In this study of 329 matched pairs, the patients with HAIs incurred higher hospitalization cost (i...

BACKGROUND: Catheter-Associated Urinary Tract Infections (CAUTIs) frequently occur in the ICU and are correlated with a significant burden. METHODS: We implemented a strategy involving a 9-element bundle, education, surveillance of CAUTI rates and clinical outcomes, monitoring compliance with bundle components, feedback of CAUTI rates and performance feedback. This was executed in 299 ICUs across 32 low- and middle-income countries (LMICs). The dependent variable was CAUTI per 1,000-UC-days, assessed at baseline and throughout the intervention, in the 2nd month, 3rd month, 4-15 months, 16-27 months, and 28-39 months...
