Filter by:This study proposes the novel use of a bedrail-affixed technology-based patient hand hygiene system with verbal and visual reminders to improve hospitalized older adults' self-management of hand hygiene practice, which in return reduces harmful germs found on older adult's hands that lead to infections.
Operating room S. aureus exposure has been directly linked to postoperative infections and is therefore an important target for infection prevention. Visible light (non-ultraviolet spectrum) at 405nm has been shown to be germicidal. We hypothesize that use of this light in operating rooms will reduce S. aureus transmission occurring within and between patients and reduce surgical site infections (SSIs). Visible light is safe for routine, continual exposure, and is less harmful than sunlight. We plan to install ambient, germicidal lighting in 4 operating rooms. This ambient light is not directly applied to patients (does not involve the surgical procedure lights). Patients will undergo surgery according to usual practice. We will conduct a case-control study where operating rooms with surgeries with the lights are matched to operating rooms with surgeries without lights. In Aim 1, 4 OR-pairs will be observed each day over an anticipated 103 working days for the primary outcome of S. aureus transmission events over a total minimum study period of 5.2 months (103 working days).
Normal gut bacteria prevent colonization and subsequent infection with MDR organisms (MDROs) through competition for resources and other mechanisms. During critical illness, this function of the microbiome is lost and there are no current treatments to restore it. Preliminary data indicates that the prebiotic fiber inulin is safe and may alter the gastrointestinal microbiome to improve gut barrier function, decrease colonization with MDROs, and reduce downstream risk for intensive care unit (ICU)-acquired MDR infections. However, the impact of inulin during critical illness is unknown. This double-blind, randomized clinical trial will test inulin for the prevention of antibiotic resistant infections in the ICU. The trial's specific aims are to determine (1) the feasibility, tolerability, and safety of inulin in the intensive care unit; (2) the impact of inulin on gut colonization with antibiotic-resistant pathogens; and (2A/exploratory) the impact of inulin on ICU-acquired antibiotic-resistant infections.
Airborne transmission represents one of the most rapidly spreading and dangerous dissemination mechanisms for pathogens. Public health strategies to prevent and control the often explosive outbreaks associated with such pathogens are: 1) vaccination and treatment, if available, 2) isolation and barrier precautions such as face masks, and 3) decontamination of the exposed areas and surfaces. A lack of understanding how these pathogens are transmitted hampers the ability to develop effective prevention measures. This study will be used to collect preliminary data of the emission patterns of respiratory pathogens.
