Contributory conditions for unexpected COVID-19 cases and nosocomial COVID-19 infection cases identified from systematic investigation in a French University Hospital.

Introduction: Nosocomial case (NC) of COVID-19 infections is a challenge for hospitals. We report the results of a seven-month prospective cohort study investigating COVID-19 patients to assess unexpected cases (UC) (no COVID-19 precautionary measure application since admission) and NC.

Patients And Methods: Investigation by an infection control team of 844 patients with COVID-19 infection hospitalized for more than 24 hours (cases).

Randomized study of antiseptic application technique in healthy volunteers before vascular access insertion (TApAS trial).

Background: In France about 32% of hospitalized patients have a vascular access placement. However, a common complication associated with these is catheter-related bloodstream infection (CRBI) due to the introduction of microorganisms from the skin during catheter insertion. There is no consensus on the best way to clean the skin prior to catheter insertion, which could be a key element of CRBI prevention.
