Antibiotic Selectors

These functions allow for filtering rows and selecting columns based on antibiotic test results that are of a specific antibiotic class or group, without the need to define the columns or antibiotic abbreviations. In short, if you have a column name that resembles an antimicrobial agent, it will be picked up by any of these functions that matches its pharmaceutical class: "cefazolin", "CZO" and "J01DB04" will all be picked up by cephalosporins().

Arguments

ab_class: an antimicrobial class or a part of it, such as "carba" and "carbapenems". The columns group, atc_group1 and atc_group2 of the antibiotics data set will be searched (case-insensitive) for this value.
only_rsi_columns: a logical to indicate whether only columns of class <rsi> must be selected (defaults to FALSE), see as.rsi()
only_treatable: a logical to indicate whether agents that are only for laboratory tests should be excluded (defaults to TRUE), such as gentamicin-high (GEH) and imipenem/EDTA (IPE)
...: ignored, only in place to allow future extensions
filter: an expression to be evaluated in the antibiotics data set, such as name %like% "trim"
col_mo: column name of the IDs of the microorganisms (see as.mo()), defaults to the first column of class mo. Values will be coerced using as.mo().
version_expertrules: the version number to use for the EUCAST Expert Rules and Intrinsic Resistance guideline. Can be either "3.3", "3.2" or "3.1".

Value

(internally) a character vector of column names, with additional class "ab_selector"

Details

These functions can be used in data set calls for selecting columns and filtering rows. They are heavily inspired by the Tidyverse selection helpers such as everything(), but also work in base R and not only in dplyr verbs. Nonetheless, they are very convenient to use with dplyr functions such as select(), filter() and summarise(), see Examples.

All columns in the data in which these functions are called will be searched for known antibiotic names, abbreviations, brand names, and codes (ATC, EARS-Net, WHO, etc.) according to the antibiotics data set. This means that a selector such as aminoglycosides() will pick up column names like 'gen', 'genta', 'J01GB03', 'tobra', 'Tobracin', etc.

The ab_class() function can be used to filter/select on a manually defined antibiotic class. It searches for results in the antibiotics data set within the columns group, atc_group1 and atc_group2.

The ab_selector() function can be used to internally filter the antibiotics data set on any results, see Examples. It allows for filtering on a (part of) a certain name, and/or a group name or even a minimum of DDDs for oral treatment. This function yields the highest flexibility, but is also the least user-friendly, since it requires a hard-coded filter to set.

The administrable_per_os() and administrable_iv() functions also rely on the antibiotics data set - antibiotic columns will be matched where a DDD (defined daily dose) for resp. oral and IV treatment is available in the antibiotics data set.

The not_intrinsic_resistant() function can be used to only select antibiotic columns that pose no intrinsic resistance for the microorganisms in the data set. For example, if a data set contains only microorganism codes or names of E. coli and K. pneumoniae and contains a column "vancomycin", this column will be removed (or rather, unselected) using this function. It currently applies 'EUCAST Expert Rules' and 'EUCAST Intrinsic Resistance and Unusual Phenotypes' v3.3 (2021) to determine intrinsic resistance, using the eucast_rules() function internally. Because of this determination, this function is quite slow in terms of performance.

Stable Lifecycle

The lifecycle of this function is stable. In a stable function, major changes are unlikely. This means that the unlying code will generally evolve by adding new arguments; removing arguments or changing the meaning of existing arguments will be avoided.

If the unlying code needs breaking changes, they will occur gradually. For example, an argument will be deprecated and first continue to work, but will emit an message informing you of the change. Next, typically after at least one newly released version on CRAN, the message will be transformed to an error.

Reference Data Publicly Available

All reference data sets (about microorganisms, antibiotics, R/SI interpretation, EUCAST rules, etc.) in this AMR package are publicly and freely available. We continually export our data sets to formats for use in R, SPSS, SAS, Stata and Excel. We also supply flat files that are machine-readable and suitable for input in any software program, such as laboratory information systems. Please find all download links on our website, which is automatically updated with every code change.

Examples

# `example_isolates` is a data set available in the AMR package.
# See ?example_isolates.

# base R ------------------------------------------------------------------

# select columns 'IPM' (imipenem) and 'MEM' (meropenem)
example_isolates[, carbapenems()]

# select columns 'mo', 'AMK', 'GEN', 'KAN' and 'TOB'
example_isolates[, c("mo", aminoglycosides())]

# select only antibiotic columns with DDDs for oral treatment
example_isolates[, administrable_per_os()]

# filter using any() or all()
example_isolates[any(carbapenems() == "R"), ]

# filter on any or all results in the carbapenem columns (i.e., IPM, MEM):
example_isolates[any(carbapenems()), ]
example_isolates[all(carbapenems()), ]

# filter with multiple antibiotic selectors using c()
example_isolates[all(c(carbapenems(), aminoglycosides()) == "R"), ]

# filter + select in one go: get penicillins in carbapenems-resistant strains
example_isolates[any(carbapenems() == "R"), penicillins()]

# You can combine selectors with '&' to be more specific. For example,
# penicillins() would select benzylpenicillin ('peni G') and
# administrable_per_os() would select erythromycin. Yet, when combined these
# drugs are both omitted since benzylpenicillin is not administrable per os
# and erythromycin is not a penicillin:
example_isolates[, penicillins() & administrable_per_os()]

# ab_selector() applies a filter in the `antibiotics` data set and is thus very
# flexible. For instance, to select antibiotic columns with an oral DDD of at
# least 1 gram:
example_isolates[, ab_selector(oral_ddd > 1 & oral_units == "g")]
