PURPOSE The purpose of this study was to determine the attributable intensive care unit (ICU) and hospital length of stay and mortality of ICU-acquired Clostridium difficile infection (CDI). MATERIALS AND METHODS In this retrospective cohort study of 3 tertiary and 3 community ICUs, we screened all patients admitted between April 2006 and December 2011(More)
OBJECTIVE We sought to estimate the period prevalence of methicillin-resistant Staphylococcus aureus (MRSA) skin and soft tissue infection (SSTI) and evaluate risk factors for MRSA SSTI in an emergency department (ED) population. METHODS We carried out a cohort study with a nested case-control design. Patients presenting to our ED with a wound culture and(More)
