Antimicrobial Selectors

Description

These functions allow for filtering rows and selecting columns based on antimicrobial test results that are of a specific antimicrobial class or group, without the need to define the columns or antimicrobial abbreviations.

In short, if you have a column name that resembles an antimicrobial drug, it will be picked up by any of these functions that matches its pharmaceutical class: "cefazolin", "kefzol", "CZO" and "J01DB04" will all be picked up using:

Arguments

only_sir_columns	a logical to indicate whether only columns of class sir must be selected (default is FALSE), see as.sir()
only_treatable	a logical to indicate whether antimicrobial drugs should be excluded that are only for laboratory tests (default is TRUE), such as gentamicin-high (GEH) and imipenem/EDTA (IPE)
return_all	a logical to indicate whether all matched columns must be returned (default is TRUE). With FALSE, only the first of each unique antimicrobial will be returned, e.g. if both columns "genta" and "gentamicin" exist in the data, only the first hit for gentamicin will be returned.
...	ignored, only in place to allow future extensions
amr_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.
filter	an expression to be evaluated in the antibiotics data set, such as name %like% "trim"
col_mo	column name of the names or codes of the microorganisms (see as.mo()) - the default is 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 "3.3", "3.2", or "3.1".

Details

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

All selectors can also be used in tidymodels packages such as recipe and parsnip. See for more info our tutorial on using antimicrobial selectors for predictive modelling.

All columns in the data in which these functions are called will be searched for known antimicrobial 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 amr_class() function can be used to filter/select on a manually defined antimicrobial class. It searches for results in the antibiotics data set within the columns group, atc_group1 and atc_group2.

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

The amr_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 not_intrinsic_resistant() function can be used to only select antimicrobials 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.

Value

When used inside selecting or filtering, this returns a character vector of column names, with additional class "amr_selector". When used individually, this returns an 'ab' vector with all possible antimicrobials that the function would be able to select or filter.

Examples

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


# you can use the selectors separately to retrieve all possible antimicrobials:
carbapenems()


# Though they are primarily intended to use for selections and filters.
# Examples sections below are split into 'dplyr', 'base R', and 'data.table':


## Not run: 
# dplyr -------------------------------------------------------------------

library(dplyr, warn.conflicts = FALSE)

example_isolates %>% select(carbapenems())

# select columns 'mo', 'AMK', 'GEN', 'KAN' and 'TOB'
example_isolates %>% select(mo, aminoglycosides())

# you can combine selectors like you are used with tidyverse
# e.g., for betalactams, but not the ones with an enzyme inhibitor:
example_isolates %>% select(betalactams(), -betalactams_with_inhibitor())

# select only antimicrobials with DDDs for oral treatment
example_isolates %>% select(administrable_per_os())

# get AMR for all aminoglycosides e.g., per ward:
example_isolates %>%
  group_by(ward) %>%
  summarise(across(aminoglycosides(),
                   resistance))

# You can combine selectors with '&' to be more specific:
example_isolates %>%
  select(penicillins() & administrable_per_os())

# get AMR for only drugs that matter - no intrinsic resistance:
example_isolates %>%
  filter(mo_genus() %in% c("Escherichia", "Klebsiella")) %>%
  group_by(ward) %>%
  summarise_at(not_intrinsic_resistant(),
               resistance)

# get susceptibility for antimicrobials whose name contains "trim":
example_isolates %>%
  filter(first_isolate()) %>%
  group_by(ward) %>%
  summarise(across(amr_selector(name %like% "trim"), susceptibility))

# this will select columns 'IPM' (imipenem) and 'MEM' (meropenem):
example_isolates %>%
  select(carbapenems())

# this will select columns 'mo', 'AMK', 'GEN', 'KAN' and 'TOB':
example_isolates %>%
  select(mo, aminoglycosides())

# any() and all() work in dplyr's filter() too:
example_isolates %>%
  filter(
    any(aminoglycosides() == "R"),
    all(cephalosporins_2nd() == "R")
  )

# also works with c():
example_isolates %>%
  filter(any(c(carbapenems(), aminoglycosides()) == "R"))

# not setting any/all will automatically apply all():
example_isolates %>%
  filter(aminoglycosides() == "R")

# this will select columns 'mo' and all antimycobacterial drugs ('RIF'):
example_isolates %>%
  select(mo, amr_class("mycobact"))

# get bug/drug combinations for only glycopeptides in Gram-positives:
example_isolates %>%
  filter(mo_is_gram_positive()) %>%
  select(mo, glycopeptides()) %>%
  bug_drug_combinations() %>%
  format()

data.frame(
  some_column = "some_value",
  J01CA01 = "S"
) %>% # ATC code of ampicillin
  select(penicillins()) # only the 'J01CA01' column will be selected

# with recent versions of dplyr, this is all equal:
x <- example_isolates[carbapenems() == "R", ]
y <- example_isolates %>% filter(carbapenems() == "R")
z <- example_isolates %>% filter(if_all(carbapenems(), ~ .x == "R"))
identical(x, y) && identical(y, z)


## End(Not run)
# 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 antimicrobials with DDDs for oral treatment
example_isolates[, administrable_per_os()]

# filter using any() or all()
example_isolates[any(carbapenems() == "R"), ]
subset(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 antimicrobial selectors using c()
example_isolates[all(c(carbapenems(), aminoglycosides()) == "R"), ]

# filter + select in one go: get penicillins in carbapenem-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()]

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


# data.table --------------------------------------------------------------

# data.table is supported as well, just use it in the same way as with
# base R, but add `with = FALSE` if using a single AB selector.

if (require("data.table")) {
  dt <- as.data.table(example_isolates)

  # this does not work, it returns column *names*
  dt[, carbapenems()]
}
if (require("data.table")) {
  # so `with = FALSE` is required
  dt[, carbapenems(), with = FALSE]
}

# for multiple selections or AB selectors, `with = FALSE` is not needed:
if (require("data.table")) {
  dt[, c("mo", aminoglycosides())]
}
if (require("data.table")) {
  dt[, c(carbapenems(), aminoglycosides())]
}

# row filters are also supported:
if (require("data.table")) {
  dt[any(carbapenems() == "S"), ]
}
if (require("data.table")) {
  dt[any(carbapenems() == "S"), penicillins(), with = FALSE]
}
