BACKGROUND Hand hygiene prevents cross infection in hospitals, but compliance with recommended instructions is commonly poor. We attempted to promote hand hygiene by implementing a hospital-wide programme, with special emphasis on bedside, alcohol-based hand disinfection. We measured nosocomial infections in parallel. METHODS We monitored the overall(More)
BACKGROUND Cross-transmission of microorganisms by the hands of health care workers is considered the main route of spread of nosocomial infections. OBJECTIVE To study the process of bacterial contamination of health care workers' hands during routine patient care in a large teaching hospital. METHODS Structured observations of 417 episodes of care were(More)
BACKGROUND Physician adherence to hand hygiene remains low in most hospitals. OBJECTIVES To identify risk factors for nonadherence and assess beliefs and perceptions associated with hand hygiene among physicians. DESIGN Cross-sectional survey of physician practices, beliefs, and attitudes toward hand hygiene. SETTING Large university hospital. (More)
OBJECTIVES To investigate a nosocomial outbreak of influenza. DESIGN Prospective outbreak investigation with active case finding and molecular typing. SETTING A large academic geriatric hospital in Switzerland. PARTICIPANTS Elderly hospitalized adults. MEASUREMENTS Based on syndromic surveillance, a nosocomial influenza outbreak was suspected in(More)
The role of asymptomatic carriers of toxigenic Clostridium difficile (TCD) in nosocomial cross-transmission remains debatable. Moreover, its relevance in the elderly has been sparsely studied. To assess asymptomatic TCD carriage in an acute care geriatric population. We performed a prospective cohort study at the 296-bed geriatric hospital of the Geneva(More)
Nosocomial infections are a major challenge for modern medicine and contribute to increased resource use in health care systems. The first hospital-wide prevalence survey of nosocomial infections was conducted at the University of Geneva Hospitals in 1994. At the time of the study, 16.9% of admitted patients had nosocomial infections (168/994). Leading(More)
Methods Retrospective cohort study of CDI patients, identified via active surveillance of the infection control program, at a 300 bed acute-care geriatric hospital in 2008-2014. We analyzed CDI incidence, surveillance case definition (hospital-onset healthcare facility–associated, HOHCFA), recurrence, demographics, antibiotic exposure, time at risk and(More)
Methods We conducted a survey on the impact of feedback and patient participation on hand hygiene compliance at our institution in 2012 and included 5 of 16 wards at the geriatric hospital. Patients were randomly recruited by an infection control nurse in 2 of the 5 wards to investigate the potential for patients to be actively engaged in hand hygiene(More)
Methods Structured observations of RT care sequences were conducted by trained external observers. At the beginning and the end of each care sequence observed, imprints of the 5 fingertips of the dominant hand, with and without gloves, were taken on blood agar plates. Bacterial colony-forming units (CFUs) were quantified after 18 hrs of incubation at 35oC.(More)
Expert systems methodology investigated within the GAMES-II European Union research project was applied in the H6pital Cantonal Universitaire of Geneva to infection control, and in particular to the control of methicillin-resistant Staphylococcus aureus (MRSA) outbreak. For detecting MRSA patients, alerts were implemented by periodic queries to the(More)
