Antimicrobial resistance (AMR) is mainly sustained by the improper use of antibiotics and has become a global public health concern both in the field of human and animal health. Italy has the highest prevalence of AMR among European countries, in particular carbapenem-resistant Klebsiella pneumoniae, which reached 34.3% in 2013. Multidrug-resistant microorganisms' infections are associated with increased risk of complications, higher hospitalization rates, increased healthcare costs, loss of productivity and increased mortality. This paper summarizes the most recent epidemiological data regarding the spread of antibiotic resistance in Italy, consumption and economic impact, outlining the need for timely action and integrated approaches in all countries.
