Main interests

  • Development, Integration and Validation of Clinical Tools Designed to Prevent and Manage Nosocomial Infections.

    The aim of this program is to develop new clinical tools that could be used to prevent and manage nosocomial infections. Two examples of current projects that fall under this program and which we direct are as follows:

    1. Multicentric prospective cohort study aimed at developing and validating a clinical prediction scale for patients with Clostridium difficile-associated diarrhea. From the clinical diagnostic data available (temperature, leuko­cytosis, etc.), it will be possible to use this scale for early identification of patients at a high risk of relapse or severe complications and improve how they are managed.
    2. Development and validation of an asynchronous computerized decisional support system to improve the use of antibiotics (ATB). Using summary clinical data (diagnosis, type of ATB, duration, etc.), the system will identify patients at risk of receiving ATBs inappropriately and recommend treastment alternatives that are less toxic, less expensive and less likely to induce resistance and trigger the onset of C. difficile.

    The longer-term objective of this program will be to expand the development and validation of these clinical tools and apply the expertise acquired to other infectious pathologies and other fields, such as the use of microbiological tests in a global context of improving medical practice and rationalizing the use of resources.
