BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of morbidity and mortality among neonates admitted to neonatal intensive care units (NICUs). The MRSA colonization of neonates, attributed to various sources, including mothers, healthcare workers, and environmental surfaces, can lead to severe infection, prolonged hospital stays, and even death, imposing substantial economic burdens. Given the pressing need to mitigate MRSA spread in these vulnerable environments, further examination of the subject is warranted...

BACKGROUND AND AIM: Methicillin-resistant coagulase-positive staphylococci (MRCoPS) cause pyoderma, dermatitis, and nosocomial infection. Numerous factors, including indiscriminate antimicrobial use (AMU) in veterinary medicine, cleaning practices, and AMU in hospitals, contribute to MRCoPS. However, the relationship between hospital age and MRCoPS has not yet been investigated. This study aimed to estimate the prevalence of MRCoPS in the treatment and operation rooms of new, middle-aged, and old veterinary hospitals...

In recent decades, minimally invasive surgery has become the favoured surgical technique, with increasing utilisation of robotic surgery to enhance patient outcomes. However, the design complexity of surgical robotic instruments can pose challenges in maintaining adequate cleaning, disinfection and sterilisation-particularly of the device's interior. In our hospital, robotic instruments are reused for a maximum of ten successive patients, following the manufacturer's guidelines. To the best of our knowledge, neither the manufacturer nor ISO standards have specified any methods to determine the sterility of robotic instruments after cleaning, disinfection and sterilisation procedures...

OBJECTIVE: To synthesize evidence and identify gaps in the literature on environmental cleaning and disinfection in the operating room based on a human factors and systems engineering approach guided by the Systems Engineering Initiative for Patient Safety (SEIPS) model. DESIGN: A systematic scoping review. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched 4 databases (ie, PubMed, EMBASE, OVID, CINAHL) for empirical studies on operating-room cleaning and disinfection...

BACKGROUND: Standard Precautions (SPs) are the minimal infection prevention and control (IPC) measures that apply to all patient care activities at all times, regardless of whether the patient has a suspected or proven disease, in any place where healthcare service is provided. These evidence-based practices protect healthcare workers (HCWs) from infection while preventing the spread of infectious agents among patients, visitors, and the environment. OBJECTIVES: Assessed compliance of HCWs working in public hospitals in Addis Ababa to infection prevention and control SPs, and factors associated with noncompliance...

Healthcare hygiene plays a crucial role in the prevention of healthcare associated infections. Patients admitted to a room where the previous occupant had a multidrug resistant bacterial infection are at an increased risk of colonisation and infection with the same organism. A 2006 systematic review by Kramer et al found that certain pathogens can survive for months on dry surfaces. The aim of this review is to update Kramer et al's previous review and provide contemporary data on the survival of pathogens relevant to the healthcare environment...

METHODS: The testing principles of the quantitative suspension test according to VAH method 9 (comparable to EN 13727) was used as a standard suspension test using 8.0 mL product test solution, 1...

PURPOSE: To identify the key infection processes and risk factors in Computed Tomography (CT) examination process within the standard prevention and control measures for the COVID-19 epidemic, aiming to mitigate cross-infection occurrences in the hospital. METHOD: The case hospital has assembled a team of 30 experts specialized in CT examination. Based on the CT examination process, the potential failure modes were assessed from the perspective of severity (S), occurrence probability (O), and detectability (D); they were then combined with corresponding risk prevention measures...

BACKGROUND: Occupational blood and body fluid exposure (OBEs) is a highly concerning global health problem in health facilities. Improper or inadequate post-exposure practices increase the risk of infection with bloodborne pathogens. Understanding risk factors for OBEs and evaluating the post-exposure practices will contribute to healthcare workers' (HCWs) well-being. METHODS: This study retrospectively synthesized and reviewed the 10-year data (from 2010 to 2020) on OBEs in a tertiary teaching hospital...

BACKGROUND: Many infections in healthcare facilities are associated with the microbiological quality of the work environment, generally due to poor sanitation. AIM: In order to evaluate the effectiveness of a decontamination protocol (cleaning + disinfection) applied at the "Université des Montagnes" Teaching Hospital, the present study assessed the variation of bacterial loads on surfaces subsequent to decontamination. Susceptibility of bacteria to disinfectants was also evaluated in the same frame...

OBJECTIVES: To compare the effect of biopsy needle disinfection with 10% formalin solution alone and with povidone-iodine rectal cleaning on preventing infectious complications requiring hospitalization. METHODS: The data of 902 patients who underwent prostate biopsy by transrectal route were retrospectively analyzed.
