Trends of antimicrobial use through selected antimicrobial indicators in Spanish hospitals, 2012 to 2021.

The results allow us to assess the national situation and the trends on antimicrobial use in the Spanish hospitalised population during the last decade. Spanish hospitals have a stable but high prevalence of antimicrobial use. Little to no improvement has been made in most of the indicators analysed, except for a reduction in the prescription of surgical prophylaxis for more than 24 hours.
