IT interventions took four main forms: 1) stand-alone computerized decision support systems (CDSSs), 2) decision support embedded within a hospital’s electronic medical record (EMR) or computerized provider order entry (CPOE) system, 3) computerized antimicrobial approval systems (cAAS), and 4) surveillance systems (SSs).

IT interventions can improve the appropriateness of antimicrobial prescribing. However, high quality, systematic multi-site comparative studies are critically needed to assist organizations in making informed decisions about the most effective IT interventions.
