Healthcare-associated infections (HAIs) are one of the main causes of morbidity and mortality worldwide. Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae have become microorganisms frequently found in HAIs, which reduces the therapeutic possibilities.
This is an interventional multicenter prospective noninferiority non-randomized double-blind controlled before and after study.~The aim of this study is to demonstrate that standard precautions alone are not inferior to contact precautions by comparing the incidence density of extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae acquired in geriatric units before and after discontinuing contact precautions.
