Influenza vaccine effectiveness among adult patients in a University of Lyon hospital (2004-2009).

The aim of this study was to estimate influenza vaccine effectiveness (IVE) against laboratory-confirmed influenza among hospitalized patients. A case-control investigation was based on the prospective surveillance of influenza-like illness (ILI) during five flu seasons. We compared influenza-positive cases and influenza-negative controls.

Factors associated with hospital mortality in community-acquired legionellosis in France.

The aims of this study were to describe the clinical, biological and radiological features of community-acquired (CA) Legionnaires' disease (LD) and identify the predictors of mortality in hospitalised patients. Demographic data, risk factors, clinical and biological features, medical management, complications, and outcome from 540 hospitalised patients with confirmed CA LD were prospectively recorded. 8.

Risk of influenza-like illness in an acute health care setting during community influenza epidemics in 2004-2005, 2005-2006, and 2006-2007: a prospective study.

Background: The person-to-person transmission of influenza-like illness (ILI) and influenza has been described mostly in long-term care units. Studies in acute hospital settings are rare and mostly retrospective.

Methods: We prospectively estimated the relative risk (RR) of hospital-acquired (HA) ILI during hospitalization according to in-hospital exposures to contagious individuals.

[Orion (Outbreak Reports and Intervention studies of Nosocomial Infection) used for evaluating interventions and investigations of nosocomial infection outbreaks].

Introduction: British colleagues have developed the Outbreak Reports and Intervention studies of Nosocomial Infection (Orion) guidelines with the aim to promote transparency of publications in the field of health-care associated infections and particularly for reports of outbreak investigation or intervention studies. The aim of this study was to translate the Orion criteria and to promote their use in France.

Results: The Orion guidelines include a checklist of 22 commented items related to the title, abstract, introduction, methods, results, and discussion sections of a scientific article.

Field test comparison of two dermal tolerance assessment methods of hand hygiene products.

This study aimed to compare the sensitivity and workload requirement of two dermal tolerance assessment methods of hand hygiene products, in order to select a suitable pilot testing method for field tests. An observer-rating method and a self-assessment method were compared in 12 voluntary hospital departments (autumn/winter of 2005-2006). Three test-periods of three weeks were separated by two-week intervals during which the routine products were reintroduced.
