mdro.RdDetermine which isolates are multidrug-resistant organisms (MDRO) according to (country-specific) guidelines.
mdro(x, guideline = NULL, col_mo = NULL, info = TRUE, verbose = FALSE, ...) brmo(x, guideline = "BRMO", ...) mrgn(x, guideline = "MRGN", ...) mdr_tb(x, guideline = "TB", ...) mdr_cmi2012(x, guideline = "CMI2012", ...) eucast_exceptional_phenotypes(x, guideline = "EUCAST", ...)
| x | table with antibiotic columns, like e.g. |
|---|---|
| guideline | a specific guideline to follow. When left empty, the publication by Magiorakos et al. (2012, Clinical Microbiology and Infection) will be followed, see Details. |
| col_mo | column name of the IDs of the microorganisms (see |
| info | print progress |
| verbose | print additional info: missing antibiotic columns per parameter |
| ... | column name of an antibiotic, see section Antibiotics |
Please see Details for the list of publications used for this function.
CMI 2012 paper - function mdr_cmi2012() or mdro():
Ordered factor with levels Negative < Multi-drug-resistant (MDR) < Extensively drug-resistant (XDR) < Pandrug-resistant (PDR)
TB guideline - function mdr_tb() or mdro(..., guideline = "TB"):
Ordered factor with levels Negative < Mono-resistant < Poly-resistant < Multi-drug-resistant < Extensively drug-resistant
German guideline - function mrgn() or mdro(..., guideline = "MRGN"):
Ordered factor with levels Negative < 3MRGN < 4MRGN
Everything else:
Ordered factor with levels Negative < Positive, unconfirmed < Positive. The value "Positive, unconfirmed" means that, according to the guideline, it is not entirely sure if the isolate is multi-drug resistant and this should be confirmed with additional (e.g. molecular) tests
Currently supported guidelines are (case-insensitive):
guideline = "CMI2012": Magiorakos AP, Srinivasan A et al. "Multidrug-resistant, extensively drug-resistant and pandrug-resistant bacteria: an international expert proposal for interim standard definitions for acquired resistance." Clinical Microbiology and Infection (2012) (link)
guideline = "EUCAST": The European international guideline - EUCAST Expert Rules Version 3.1 "Intrinsic Resistance and Exceptional Phenotypes Tables" (link)
guideline = "TB": The international guideline for multi-drug resistant tuberculosis - World Health Organization "Companion handbook to the WHO guidelines for the programmatic management of drug-resistant tuberculosis" (link)
guideline = "MRGN": The German national guideline - Mueller et al. (2015) Antimicrobial Resistance and Infection Control 4:7. DOI: 10.1186/s13756-015-0047-6
guideline = "BRMO": The Dutch national guideline - Rijksinstituut voor Volksgezondheid en Milieu "WIP-richtlijn BRMO (Bijzonder Resistente Micro-Organismen) [ZKH]" (link)

To define antibiotics column names, leave as it is to determine it automatically with guess_ab_col or input a text (case-insensitive), or use NULL to skip a column (e.g. TIC = NULL to skip ticarcillin). Manually defined but non-existing columns will be skipped with a warning.
