#' Generate Antibiogram: Traditional, Combined, Syndromic, or Weighted-Incidence Syndromic Combination (WISCA)
|
|
#'
|
|
#' Generate an antibiogram, and communicate the results in plots or tables. These functions follow the logic of Klinker *et al.* and Barbieri *et al.* (see *Source*), and allow reporting in e.g. R Markdown and Quarto as well.
|
|
#' @param x a [data.frame] containing at least a column with microorganisms and columns with antibiotic results (class 'sir', see [as.sir()])
|
|
#' @param antibiotics vector of any antibiotic name or code (will be evaluated with [as.ab()], column name of `x`, or (any combinations of) [antibiotic selectors][antibiotic_class_selectors] such as [aminoglycosides()] or [carbapenems()]. For combination antibiograms, this can also be set to values separated with `"+"`, such as "TZP+TOB" or "cipro + genta", given that columns resembling such antibiotics exist in `x`. See *Examples*.
|
|
#' @param mo_transform a character to transform microorganism input - must be "name", "shortname", "gramstain", or one of the column names of the [microorganisms] data set: `r vector_or(colnames(microorganisms), sort = FALSE, quotes = TRUE)`. Can also be `NULL` to not transform the input.
|
|
#' @param ab_transform a character to transform antibiotic input - must be one of the column names of the [antibiotics] data set: `r vector_or(colnames(antibiotics), sort = FALSE, quotes = TRUE)`. Can also be `NULL` to not transform the input.
|
|
#' @param syndromic_group a column name of `x`, or values calculated to split rows of `x`, e.g. by using [ifelse()] or [`case_when()`][dplyr::case_when()]. See *Examples*.
|
|
#' @param add_total_n a [logical] to indicate whether total available numbers per pathogen should be added to the table (default is `TRUE`). This will add the lowest and highest number of available isolate per antibiotic (e.g, if for *E. coli* 200 isolates are available for ciprofloxacin and 150 for amoxicillin, the returned number will be "150-200").
|
|
#' @param only_all_tested (for combination antibiograms): a [logical] to indicate that isolates must be tested for all antibiotics, see *Details*
|
|
#' @param digits number of digits to use for rounding
|
|
#' @param 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()].
|
|
#' @param language language to translate text, which defaults to the system language (see [get_AMR_locale()])
|
|
#' @param minimum the minimum allowed number of available (tested) isolates. Any isolate count lower than `minimum` will return `NA` with a warning. The default number of `30` isolates is advised by the Clinical and Laboratory Standards Institute (CLSI) as best practice, see *Source*.
|
|
#' @param combine_SI a [logical] to indicate whether all susceptibility should be determined by results of either S or I, instead of only S (default is `TRUE`)
|
|
#' @param sep a separating character for antibiotic columns in combination antibiograms
|
|
#' @param info a [logical] to indicate info should be printed - the default is `TRUE` only in interactive mode
|
|
#' @param object an [antibiogram()] object
|
|
#' @param ... when used in [R Markdown or Quarto][knitr::kable()]: arguments passed on to [knitr::kable()] (otherwise, has no use)
|
|
#' @details This function returns a table with values between 0 and 100 for *susceptibility*, not resistance.
|
|
#'
|
|
#' **Remember that you should filter your data to let it contain only first isolates!** This is needed to exclude duplicates and to reduce selection bias. Use [first_isolate()] to determine them in your data set with one of the four available algorithms.
|
|
#'
|
|
#' All types of antibiograms as listed below can be plotted (using [ggplot2::autoplot()] or base \R [plot()]/[barplot()]). The `antibiogram` object can also be used directly in R Markdown / Quarto (i.e., `knitr`) for reports. In this case, [knitr::kable()] will be applied automatically and microorganism names will even be printed in italics at default (see argument `italicise`). You can also use functions from specific 'table reporting' packages to transform the output of [antibiogram()] to your needs, e.g. with `flextable::as_flextable()` or `gt::gt()`.

|
|
#' ### Antibiogram Types
|
|
#'
|
|
#' There are four antibiogram types, as proposed by Klinker *et al.* (2021, \doi{10.1177/20499361211011373}), and they are all supported by [antibiogram()]:
|
|
#'
|
|
#' 1. **Traditional Antibiogram**
|
|
#'
|
|
#' Case example: Susceptibility of *Pseudomonas aeruginosa* to piperacillin/tazobactam (TZP)
|
|
#'
|
|
#' Code example:
|
|
#'
|
|
#' ```r
|
|
#' antibiogram(your_data,
|
|
#' antibiotics = "TZP")
|
|
#' ```
|
|
#'
|
|
#' 2. **Combination Antibiogram**
|
|
#'
|
|
#' Case example: Additional susceptibility of *Pseudomonas aeruginosa* to TZP + tobramycin versus TZP alone
|
|
#'
|
|
#' Code example:
|
|
#'
|
|
#' ```r
|
|
#' antibiogram(your_data,
|
|
#' antibiotics = c("TZP", "TZP+TOB", "TZP+GEN"))
|
|
#' ```
|
|
#'
|
|
#' 3. **Syndromic Antibiogram**
|
|
#'
|
|
#' Case example: Susceptibility of *Pseudomonas aeruginosa* to TZP among respiratory specimens (obtained among ICU patients only)
|
|
#'
|
|
#' Code example:
|
|
#'
|
|
#' ```r
|
|
#' antibiogram(your_data,
|
|
#' antibiotics = penicillins(),
|
|
#' syndromic_group = "ward")
|
|
#' ```
|
|
#'
|
|
#' 4. **Weighted-Incidence Syndromic Combination Antibiogram (WISCA)**
|
|
#'
|
|
#' Case example: Susceptibility of *Pseudomonas aeruginosa* to TZP among respiratory specimens (obtained among ICU patients only) for male patients age >=65 years with heart failure
|
|
#'
|
|
#' Code example:
|
|
#'
|
|
#' ```r
|
|
#' library(dplyr)
|
|
#' your_data %>%
|
|
#' filter(ward == "ICU" & specimen_type == "Respiratory") %>%
|
|
#' antibiogram(antibiotics = c("TZP", "TZP+TOB", "TZP+GEN"),
|
|
#' syndromic_group = ifelse(.$age >= 65 &
|
|
#' .$gender == "Male" &
|
|
#' .$condition == "Heart Disease",
|
|
#' "Study Group", "Control Group"))
|
|
#' ```
|
|
#'
|
|
#' Note that for combination antibiograms, it is important to realise that susceptibility can be calculated in two ways, which can be set with the `only_all_tested` argument (default is `FALSE`). See this example for two antibiotics, Drug A and Drug B, about how [antibiogram()] works to calculate the %SI:
|
|
#'
|
|
#' ```
|
|
#' --------------------------------------------------------------------
|
|
#' only_all_tested = FALSE only_all_tested = TRUE
|

#' Drug A Drug B include as include as include as include as
