Healthcare-associated infections due to multidrug-resistant organisms: a surveillance study on extra hospital stay and direct costs
BACKGROUND: The increasing antimicrobial resistance poses a challenge for surveillance systems and raises concerns about the impact of multidrug-resistant organisms on patient safety. OBJECTIVE: To estimate extra hospital stay and economic burden of infections due to alert organisms - mostly multidrug-resistant - in a teaching hospital. METHODS: The present retrospective matched cohort study was conducted through the analysis of hospital admissions at Sant'Andrea Teaching Hospital in Rome from April to December 2015.
