ANRESIS Inpatient Dataset
The data in this interactive graph come from a network of voluntary acute hospitals participating in the ANRESIS surveillance system. Data from outpatient, rehabilitation and geriatric and psychiatric long-term care units in these hospitals are excluded as their activity could bias the results. Data were collected for the entire hospital and, where available, for the adult intensive care units separately. Data on hospital days were collected, allowing consumption to be expressed as DDD per 100 bed days.

AWaRe Classification of antibiotics
In the revision of the WHO Model List of Essential Medicines (EML), antibiotics have been grouped into a new classification as metric for antibacterial use: the AWaRe classification system [1]. This classification system classifies key antibiotics into three categories; Access, Watch, and Reserve. It was developed as a simple stewardship intervention tool that is applicable worldwide (www.adoptaware.com).

  • Access group
    This group contains the antibiotics of first choice for each of the 25 most common infections. These antibiotics minimize the potential for resistance.
  • Watch Group
    This group includes most of the "highest-priority critically important antimicrobials (HPCIA)" for human use. These antibiotics are recommended only for specific, limited indications.
  • Reserve Group
    This group contains antibiotics which should only be used as a last resort when all other antibiotics have failed.
