Study Evaluating Severe Surgical Site Infections (SSIs) Following Contaminated Or Dirty-infected Abdominal Surgery (EURIDICE)
9. Mai 2012 aktualisiert von: Pfizer
A Multicenter, Surgeon-Matched Case-Control Study of Severe Surgical Site Infections (SSIs) Following Contaminated Or Dirty-infected Abdominal Surgery
This is an observational study to evaluate the relative importance of the known risk factors for severe surgical site infections (SSIs) on the development of the more severe SSI cases, and to describe the demographic, clinical features, etiology and the management and outcome of patients suffering from severe SSIs in Spain.
