Determine which isolates are multidrug-resistant organisms (MDRO) according to country-specific guidelines.

mdro(x, country = NULL, col_mo = NULL, info = TRUE,
  verbose = FALSE, ...)

brmo(..., country = "nl")

mrgn(x, country = "de", ...)

eucast_exceptional_phenotypes(x, country = "EUCAST", ...)

Arguments

x

table with antibiotic columns, like e.g. AMX and AMC

country

country code to determine guidelines. EUCAST rules will be used when left empty, see Details. Should be or a code from the list of ISO 3166-1 alpha-2 country codes. Case-insensitive. Currently supported are de (Germany) and nl (the Netherlands).

col_mo

column name of the unique IDs of the microorganisms (see mo), defaults to the first column of class mo. Values will be coerced using as.mo.

info

print progress

verbose

print additional info: missing antibiotic columns per parameter

...

column name of an antibiotic, see section Antibiotics

Value

Ordered factor with levels Negative < Positive, unconfirmed < Positive.

Details

When country will be left blank, guidelines will be taken from EUCAST Expert Rules Version 3.1 "Intrinsic Resistance and Exceptional Phenotypes Tables" (link).

Antibiotics

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.
