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)
This article reports on the main developmental stages and on the preliminary psychometric assessment of the final French version of the SF-36. A standard forward/backward translation procedure was followed. When translating survey items, the emphasis was placed on conceptual equivalence. When translating response choices, we attempted to select a set of(More)
BACKGROUND Transmission of microorganisms from the hands of health care workers is the main source of cross-infection in hospitals and can be prevented by handwashing. OBJECTIVE To identify predictors of noncompliance with handwashing during routine patient care. DESIGN Observational study. SETTING Teaching hospital in Geneva, Switzerland. (More)
Acute renal failure (ARF) in critically ill patients is associated with high mortality. Optimal method and dose of continuous renal replacement therapy could improve survival in these patients. We studied the hypothesis that an increase in dialysis dose obtained by continuous veno-venous hemodiafiltration (CVVHDF) is associated with a better survival than(More)
AIMS To assess the validity of the Fagerström test for nicotine dependence (FTND, six items) and of a short-form of this questionnaire, the Heaviness of Smoking Index (HSI, two items), in a population of relatively light smokers. DESIGN Comparison of item content with published definitions of addiction. Test-retest reliability and multiple tests of(More)
The MOS 36-Item Short Form Health Survey (SF-36) is designed to measure 8 dimensions of health in clinical and general population settings. The main aim of this paper was to examine the reliability and validity of this instrument in young adults. A secondary aim was to document the results of a rapid translation procedure of the instrument, to be compared(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)
PURPOSE Two prediction rules for pulmonary embolism have been described recently: the Wells' rule, which was derived from both outpatients and inpatients, and which includes a subjective element; and the Geneva rule, which is entirely standardized and is suitable only for emergency department patients. We compared the predictive accuracy and the concordance(More)
