Revision as of 21:04, 2 October 2022
Background
- Microorganisms, predominantly bacteria, that are resistant to one or more classes of antimicrobial agents
- Definition varies from hospital to hospital or country to country
- Generally includes the following bacteria:
- Gram-positives
- MRSA
- VRE
- Multidrug-resistant Streptococcus pneumoniae
- Gram-negatives:
- Gram-positives
European CDC Definitions
- Defined by the European CDC[1] as non-susceptibility to at least one agent in three or more categories of antimicrobials, with the categories varying by organism
- Multidrug resistant (MDR) is non-susceptible to at least 1 agent in at least 3 categories
- For Staphylococcus aureus, it automatically includes MRSA, but requires resistance in >3 categories
- Extensively drug-resistant (XDR) is non-susceptible to at least 1 agent in all but 2 categories
- Pan-drug resistant (PDR) is non-susceptible to all listed agents
- For species with intrinsic resistance to a category or agent, it should be excluded before counting
