### New
|
||||
* Function `custom_eucast_rules()` that brings support for custom AMR rules in `eucast_rules()`
|
||||
* Support for all four methods to determine first isolates as summarised by Hindler *et al* (doi: [10.1086/511864](https://doi.org/10.1086/511864)): isolate-based, patient-based, episode-based and phenotype-based. The last method is now the default.
|
||||
* Since fungal isolates can also be selected, new functions `key_antimicrobials()` and `all_antimicrobials()` have replaced the now deprecated function `key_antibiotics()`
|
||||
* Using `key_antimicrobials()` still only selects six preferred antibiotics for Gram-negatives, six for Gram-positives, and six universal antibiotics. It has a new `antifungal` argument to set antifungal agents (antimycotics).
|
||||
* The `first_isolate()` function gained the argument `method` that has to be "phenotype-based", "episode-based", "patient-based", or "isolate-based". The old behaviour is equal to "episode-based", while the new default is "phenotype-based".
|
||||
* Using `type == "points"` in the `first_isolate()` function for phenotype-based selection will now consider all antimicrobial drugs in the data set, using the new `all_antimicrobials()`
|
||||
* The `first_isolate()` function can now take a vector of values for `col_keyantibiotics` and can have an episode length of `Inf`
|
||||
* The `filter_first_isolate()` function has not changed, as it uses the episode-based method. The `filter_first_weighted_isolate()` may now include more isolates as uses the phenotype-based method.
|
||||
* The documentation of the `first_isolate()` and `key_antimicrobials()` functions has been completely rewritten.
|
||||
|
||||

* The `example_isolates` data set now contains some (fictitious) zero-year old patients

|

#' @details
|
||||
#' To conduct epidemiological analyses on antimicrobial resistance data, only so-called first isolates should be included to prevent overestimation and underestimation of antimicrobial resistance. Different algorithms can be used to do so, see below.
|
||||
#'
|
||||
#' These functions are context-aware. This means that then the `x` argument can be left blank, see *Examples*.
|
||||
#'
|
||||
#' The [first_isolate()] function is a wrapper around the [is_new_episode()] function, but more efficient for data sets containing microorganism codes or names.
|
||||
#'
|
||||
#' All isolates with a microbial ID of `NA` will be excluded as first isolate.
|
||||
#'
|
||||
#' ## Why this is so Important
|
||||
#' To conduct an analysis of antimicrobial resistance, you should only include the first isolate of every patient per episode [(Hindler *et al.* 2007)](https://pubmed.ncbi.nlm.nih.gov/17304462/). If you would not do this, you could easily get an overestimate or underestimate of the resistance of an antibiotic. Imagine that a patient was admitted with an MRSA and that it was found in 5 different blood cultures the following week. The resistance percentage of oxacillin of all *S. aureus* isolates would be overestimated, because you included this MRSA more than once. It would be [selection bias](https://en.wikipedia.org/wiki/Selection_bias).
|
||||
#'
|
||||
#' ## `filter_*()` Shortcuts
|
||||
#'
|
||||
#' The functions [filter_first_isolate()] and [filter_first_weighted_isolate()] are helper functions to quickly filter on first isolates.
|
||||
#' ## Different algorithms
|
||||
#'
|
||||
#' The function [filter_first_isolate()] is essentially equal to either:
|
||||
#' According to Hindler *et al.* (2007, \doi{10.1086/511864}), there are different algorithms to select first isolates with increasing reliability: isolate-based, patient-based, episode-based and phenotype-based. All algorithms select on a combination of the taxonomic genus and species (not subspecies).
|
||||
#'
|
||||
#' ```
|
||||
#' x[first_isolate(x, ...), ]
|
||||
#'
|
||||
#' x %>% filter(first_isolate(...))
|
||||
#' ```
|
||||
#' All mentioned algorithms are covered in the [first_isolate()] function:
|
||||
#'
|
||||
#' The function [filter_first_weighted_isolate()] is essentially equal to:
|
||||
#'
|
||||
#' ```
|
||||
#' x %>%
|
||||
#' mutate(keyab = key_antibiotics(.)) %>%
|
||||
#' mutate(only_weighted_firsts = first_isolate(x,
|
||||
#' col_keyantibiotics = "keyab", ...)) %>%
|
||||
#' filter(only_weighted_firsts == TRUE) %>%
|
||||
#' select(-only_weighted_firsts, -keyab)
|
||||
#' ```
|
||||
#' @section Key Antibiotics:
|
||||
#' There are two ways to determine whether isolates can be included as first weighted isolates which will give generally the same results:
|
||||
#'
|
||||
#' 1. Using `type = "keyantibiotics"` and argument `ignore_I`
|
||||
#' | **Algorithm** | **Function to apply** |
|
||||
#' |--------------------------------------------------|-------------------------------------------------------|
|
||||
#' | Isolate-based | `first_isolate(x, method = "isolate-based")` |
|
||||
#' | *(= all isolates)* | |
|
||||
#' | | |
|
||||
#' | | |
|
||||
#' | Patient-based | `first_isolate(x, method = "patient-based")` |
|
||||
#' | *(= first isolate per patient)* | |
|
||||
#' | | |
|
||||
#' | | |
|
||||
#' | Episode-based | `first_isolate(x, method = "episode-based")`, or: |
|
||||
#' | *(= first isolate per episode)* | |
|
||||
#' | - 7-Day interval from initial isolate | - `first_isolate(x, method = "e", episode_days = 7)` |
|
||||
#' | - 30-Day interval from initial isolate | - `first_isolate(x, method = "e", episode_days = 30)` |
|
||||
#' | | |
|
||||
#' | | |
|
||||
#' | Phenotype-based | `first_isolate(x, method = "phenotype-based")`, or: |
|
||||
#' | *(= first isolate per phenotype)* | |
|
||||
#' | - Major difference in any antimicrobial result | - `first_isolate(x, type = "points")` |
|
||||
#' | - Any difference in key antimicrobial results | - `first_isolate(x, type = "keyantimicrobials")` |
|
||||
#'
|
||||
#' Any difference from S to R (or vice versa) will (re)select an isolate as a first weighted isolate. With `ignore_I = FALSE`, also differences from I to S|R (or vice versa) will lead to this. This is a reliable method and 30-35 times faster than method 2. Read more about this in the [key_antibiotics()] function.
|
||||
#' ### Isolate-based
|
||||
#'
|
||||
#' This algorithm does not require any selection, as all isolates should be included. It does, however, respect all arguments set in the [first_isolate()] function. For example, the default setting for `include_unknown` (`FALSE`) will omit selection of rows without a microbial ID.
|
||||
#'
|
||||
#' ### Patient-based
|
||||
#'
|
||||
#' To include every genus-species combination per patient once, set the `episode_days` to `Inf`. Although often inappropriate, this algorithm makes sure that no duplicate isolates are selected from the same patient.
|
||||
#'
|
||||
#' ### Episode-based
|
||||
#'
|
||||
#' To include every genus-species combination per patient episode once, set the `episode_days` to a sensible number of days. Depending on the type of analysis, this could be 14, 30, 60 or 365. Short episodes are common for analysing specific hospital or ward data, long episodes are common for analysing regional and national data.
|
||||
#'
|
||||
#' This is the most common algorithm to correct for duplicate isolates. Patients are categorised into episodes based on their ID and dates (e.g., the date of specimen receipt or laboratory result). While this is a common algorithm, it does not take into account antimicrobial test results. This means that e.g. a methicillin-resistant *Staphylococcus aureus* (MRSA) isolate cannot be differentiated from a wildtype *Staphylococcus aureus* isolate.
|
||||
#'
|
||||
#' ### Phenotype-based
|
||||
#'
|
||||
#' This is a more reliable algorithm, since it also *weighs* the antibiogram (antimicrobial test results) yielding so-called 'first weighted isolates'. There are two different methods to weigh the antibiogram:
|
||||
#'
|
||||
#' 1. Using `type = "points"` and argument `points_threshold`
|
||||
#'
|
||||
#' This method weighs *all* antimicrobial agents available in the data set. Any difference from I to S or R (or vice versa) counts as 0.5 points, a difference from S to R (or vice versa) counts as 1 point. When the sum of points exceeds `points_threshold`, which defaults to `2`, an isolate will be selected as a first weighted isolate.
|
||||
#'
|
||||
#' 2. Using `type = "points"` and argument `points_threshold`
|
||||
#' All antimicrobials are internally selected using the [all_antimicrobials()] function. The output of this function does not need to be passed to the [first_isolate()] function.
|
||||
#'
|
||||
#' A difference from I to S|R (or vice versa) means 0.5 points, a difference from S to R (or vice versa) means 1 point. When the sum of points exceeds `points_threshold`, which defaults to `2`, an isolate will be (re)selected as a first weighted isolate.
|
||||
#'
|
||||
#' 2. Using `type = "keyantimicrobials"` and argument `ignore_I`
|
||||
#'
|
||||
#' This method only weighs specific antimicrobial agents, called *key antimicrobials*. Any difference from S to R (or vice versa) in these key antimicrobials will select an isolate as a first weighted isolate. With `ignore_I = FALSE`, also differences from I to S or R (or vice versa) will lead to this.
|
||||
#'
|
||||
#' Key antimicrobials are internally selected using the [key_antimicrobials()] function, but can also be added manually as a variable to the data and set in the `col_keyantimicrobials` argument. Another option is to pass the output of the [key_antimicrobials()] function directly to the `col_keyantimicrobials` argument.
|
||||
#'
|
||||
#'
|
||||
#' The default algorithm is phenotype-based (using `type = "points"`) and episode-based (using `episode_days = 365`). This makes sure that every genus-species combination is selected per patient once per year, while taking into account all antimicrobial test results.

#' Key Antibiotics for First (Weighted) Isolates
|
||||
#'
|
||||
#' These function can be used to determine first isolates (see [first_isolate()]). Using key antibiotics to determine first isolates is more reliable than without key antibiotics. These selected isolates can then be called first 'weighted' isolates.
|
||||
#' @inheritSection lifecycle Stable Lifecycle
|
||||
#' @param x a [data.frame] with antibiotics columns, like `AMX` or `amox`. Can be left blank to determine automatically
|
||||
#' @param y,z character vectors to compare
|
||||
#' @inheritParams first_isolate
|
||||
#' @param universal_1,universal_2,universal_3,universal_4,universal_5,universal_6 column names of **broad-spectrum** antibiotics, case-insensitive. See details for which antibiotics will be used at default (which are guessed with [guess_ab_col()]).
|
||||
#' @param GramPos_1,GramPos_2,GramPos_3,GramPos_4,GramPos_5,GramPos_6 column names of antibiotics for **Gram-positives**, case-insensitive. See details for which antibiotics will be used at default (which are guessed with [guess_ab_col()]).
|
||||
#' @param GramNeg_1,GramNeg_2,GramNeg_3,GramNeg_4,GramNeg_5,GramNeg_6 column names of antibiotics for **Gram-negatives**, case-insensitive. See details for which antibiotics will be used at default (which are guessed with [guess_ab_col()]).
|
||||
#' @param warnings give a warning about missing antibiotic columns (they will be ignored)
|
||||
#' @param ... other arguments passed on to functions
|
||||
#' @details
|
||||
#' The [key_antibiotics()] function is context-aware. This means that then the `x` argument can be left blank, see *Examples*.
|
||||
#'
|
||||
#' The function [key_antibiotics()] returns a character vector with 12 antibiotic results for every isolate. These isolates can then be compared using [key_antibiotics_equal()], to check if two isolates have generally the same antibiogram. Missing and invalid values are replaced with a dot (`"."`) by [key_antibiotics()] and ignored by [key_antibiotics_equal()].
|
||||
#'
|
||||
#' The [first_isolate()] function only uses this function on the same microbial species from the same patient. Using this, e.g. an MRSA will be included after a susceptible *S. aureus* (MSSA) is found within the same patient episode. Without key antibiotic comparison it would not. See [first_isolate()] for more info.
|
||||
#'
|
||||
#' At default, the antibiotics that are used for **Gram-positive bacteria** are:
|
||||
#' - Amoxicillin
|
||||
#' - Amoxicillin/clavulanic acid
|
||||
#' - Cefuroxime
|

#' - Piperacillin/tazobactam
|

|

#' - Tetracycline
|
||||
#' - Erythromycin
|
||||
#' - Oxacillin
|
||||
#' - Rifampin
|
||||
#'
|
||||
#' At default the antibiotics that are used for **Gram-negative bacteria** are:
|
||||
#' - Amoxicillin
|

#' - Amoxicillin/clavulanic acid
|

#' - Cefuroxime
|

#' - Cefotaxime
|
||||
#' - Ceftazidime
|
||||
#' - Meropenem
|
||||
#'
|

#' (Key) Antimicrobials for First Weighted Isolates
|
||||
#'
|
||||
#' These functions can be used to determine first weighted isolates by considering the phenotype for isolate selection (see [first_isolate()]). Using a phenotype-based method to determine first isolates is more reliable than methods that disregard phenotypes.

#' @inheritSection lifecycle Stable Lifecycle
|
||||
#' @param x a [data.frame] with antibiotics columns, like `AMX` or `amox`. Can be left blank to determine automatically
|
||||
#' @param y,z character vectors to compare
|
||||
#' @inheritParams first_isolate
|
||||
#' @param universal names of **broad-spectrum** antimicrobial agents, case-insensitive. Set to `NULL` to ignore. See *Details* for the default agents.
|
||||
#' @param gram_negative names of antibiotic agents for **Gram-positives**, case-insensitive. Set to `NULL` to ignore. See *Details* for the default agents.
|
||||
#' @param gram_positive names of antibiotic agents for **Gram-negatives**, case-insensitive. Set to `NULL` to ignore. See *Details* for the default agents.
|
||||
#' @param antifungal names of antifungal agents for **fungi**, case-insensitive. Set to `NULL` to ignore. See *Details* for the default agents.

#' @param ... ignored, allows for future extensions
|

#' @details
|
||||
#' The [key_antimicrobials()] and [all_antimicrobials()] functions are context-aware. This means that then the `x` argument can be left blank, see *Examples*.
|
||||
#'
|
||||
#' The function [key_antimicrobials()] returns a character vector with 12 antimicrobial results for every isolate. The function [all_antimicrobials()] returns a character vector with all antimicrobial results for every isolate. These vectors can then be compared using [antimicrobials_equal()], to check if two isolates have generally the same antibiogram. Missing and invalid values are replaced with a dot (`"."`) by [key_antimicrobials()] and ignored by [antimicrobials_equal()].
|
||||
#'
|
||||
#' Please see the [first_isolate()] function how these important functions enable the 'phenotype-based' method for determination of first isolates.

<li>Function <code><a href="../reference/custom_eucast_rules.html">custom_eucast_rules()</a></code> that brings support for custom AMR rules in <code><a href="../reference/eucast_rules.html">eucast_rules()</a></code>
|
||||
</li>
|
||||
<li>Support for all four methods to determine first isolates as summarised by Hindler <em>et al</em> (doi: <a href="https://doi.org/10.1086/511864">10.1086/511864</a>): isolate-based, patient-based, episode-based and phenotype-based. The last method is now the default.
|
||||
<ul>
|
||||
<li>Since fungal isolates can also be selected, new functions <code><a href="../reference/key_antimicrobials.html">key_antimicrobials()</a></code> and <code><a href="../reference/key_antimicrobials.html">all_antimicrobials()</a></code> have replaced the now deprecated function <code><a href="../reference/AMR-deprecated.html">key_antibiotics()</a></code>
|
||||
</li>
|
||||
<li>Using <code><a href="../reference/key_antimicrobials.html">key_antimicrobials()</a></code> still only selects six preferred antibiotics for Gram-negatives, six for Gram-positives, and six universal antibiotics. It has a new <code>antifungal</code> argument to set antifungal agents (antimycotics).</li>
|
||||
<li>The <code><a href="../reference/first_isolate.html">first_isolate()</a></code> function gained the argument <code>method</code> that has to be “phenotype-based”, “episode-based”, “patient-based”, or “isolate-based”. The old behaviour is equal to “episode-based”, while the new default is “phenotype-based”.</li>
|
||||
<li>Using <code>type == "points"</code> in the <code><a href="../reference/first_isolate.html">first_isolate()</a></code> function for phenotype-based selection will now consider all antimicrobial drugs in the data set, using the new <code><a href="../reference/key_antimicrobials.html">all_antimicrobials()</a></code>
|
||||
</li>
|
||||
<li>The <code><a href="../reference/first_isolate.html">first_isolate()</a></code> function can now take a vector of values for <code>col_keyantibiotics</code> and can have an episode length of <code>Inf</code>
|
||||
</li>
|
||||
<li>The <code><a href="../reference/first_isolate.html">filter_first_isolate()</a></code> function has not changed, as it uses the episode-based method. The <code><a href="../reference/first_isolate.html">filter_first_weighted_isolate()</a></code> may now include more isolates as uses the phenotype-based method.</li>
|
||||
<li>The documentation of the <code><a href="../reference/first_isolate.html">first_isolate()</a></code> and <code><a href="../reference/key_antimicrobials.html">key_antimicrobials()</a></code> functions has been completely rewritten.</li>

<p>To conduct an analysis of antimicrobial resistance, you should only include the first isolate of every patient per episode <a href='https://pubmed.ncbi.nlm.nih.gov/17304462/'>(Hindler <em>et al.</em> 2007)</a>. If you would not do this, you could easily get an overestimate or underestimate of the resistance of an antibiotic. Imagine that a patient was admitted with an MRSA and that it was found in 5 different blood cultures the following week. The resistance percentage of oxacillin of all <em>S. aureus</em> isolates would be overestimated, because you included this MRSA more than once. It would be <a href='https://en.wikipedia.org/wiki/Selection_bias'>selection bias</a>.</p>

<h2 class="hasAnchor" id="key-antibiotics"><a class="anchor" href="#key-antibiotics"></a>Key Antibiotics</h2>
|
||||
<p>This algorithm does not require any selection, as all isolates should be included. It does, however, respect all arguments set in the <code>first_isolate()</code> function. For example, the default setting for <code>include_unknown</code> (<code>FALSE</code>) will omit selection of rows without a microbial ID.</p>
|
||||
|
||||
|
||||
<h4 class='hasAnchor' id='arguments'><a class='anchor' href='#arguments'></a>Patient-based</h4>
|
||||
|
||||
<p>There are two ways to determine whether isolates can be included as first weighted isolates which will give generally the same results:</p><ol>
|
||||
<li><p>Using <code>type = "keyantibiotics"</code> and argument <code>ignore_I</code></p>
|
||||
<p>Any difference from S to R (or vice versa) will (re)select an isolate as a first weighted isolate. With <code>ignore_I = FALSE</code>, also differences from I to S|R (or vice versa) will lead to this. This is a reliable method and 30-35 times faster than method 2. Read more about this in the <code><a href='key_antibiotics.html'>key_antibiotics()</a></code> function.</p></li>
|
||||
|
||||
<p>To include every genus-species combination per patient once, set the <code>episode_days</code> to <code>Inf</code>. Although often inappropriate, this algorithm makes sure that no duplicate isolates are selected from the same patient.</p>
|
||||
|
||||
<h4 class='hasAnchor' id='arguments'><a class='anchor' href='#arguments'></a>Episode-based</h4>
|
||||
|
||||
|
||||
<p>To include every genus-species combination per patient episode once, set the <code>episode_days</code> to a sensible number of days. Depending on the type of analysis, this could be 14, 30, 60 or 365. Short episodes are common for analysing specific hospital or ward data, long episodes are common for analysing regional and national data.</p>
|
||||
<p>This is the most common algorithm to correct for duplicate isolates. Patients are categorised into episodes based on their ID and dates (e.g., the date of specimen receipt or laboratory result). While this is a common algorithm, it does not take into account antimicrobial test results. This means that e.g. a methicillin-resistant <em>Staphylococcus aureus</em> (MRSA) isolate cannot be differentiated from a wildtype <em>Staphylococcus aureus</em> isolate.</p>
|
||||
|
||||
<h4 class='hasAnchor' id='arguments'><a class='anchor' href='#arguments'></a>Phenotype-based</h4>
|
||||
|
||||
|
||||
<p>This is a more reliable algorithm, since it also <em>weighs</em> the antibiogram (antimicrobial test results) yielding so-called 'first weighted isolates'. There are two different methods to weigh the antibiogram:</p><ol>
|
||||
<li><p>Using <code>type = "points"</code> and argument <code>points_threshold</code></p>
|
||||
<p>A difference from I to S|R (or vice versa) means 0.5 points, a difference from S to R (or vice versa) means 1 point. When the sum of points exceeds <code>points_threshold</code>, which defaults to <code>2</code>, an isolate will be (re)selected as a first weighted isolate.</p></li>
|
||||
<p>This method weighs <em>all</em> antimicrobial agents available in the data set. Any difference from I to S or R (or vice versa) counts as 0.5 points, a difference from S to R (or vice versa) counts as 1 point. When the sum of points exceeds <code>points_threshold</code>, which defaults to <code>2</code>, an isolate will be selected as a first weighted isolate.</p>
|
||||
<p>All antimicrobials are internally selected using the <code><a href='key_antimicrobials.html'>all_antimicrobials()</a></code> function. The output of this function does not need to be passed to the <code>first_isolate()</code> function.</p></li>
|
||||
<li><p>Using <code>type = "keyantimicrobials"</code> and argument <code>ignore_I</code></p>
|
||||
<p>This method only weighs specific antimicrobial agents, called <em>key antimicrobials</em>. Any difference from S to R (or vice versa) in these key antimicrobials will select an isolate as a first weighted isolate. With <code>ignore_I = FALSE</code>, also differences from I to S or R (or vice versa) will lead to this.</p>
|
||||
<p>Key antimicrobials are internally selected using the <code><a href='key_antimicrobials.html'>key_antimicrobials()</a></code> function, but can also be added manually as a variable to the data and set in the <code>col_keyantimicrobials</code> argument. Another option is to pass the output of the <code><a href='key_antimicrobials.html'>key_antimicrobials()</a></code> function directly to the <code>col_keyantimicrobials</code> argument.</p></li>
|
||||
</ol>
|
||||
|
||||
<p>The default algorithm is phenotype-based (using <code>type = "points"</code>) and episode-based (using <code>episode_days = 365</code>). This makes sure that every genus-species combination is selected per patient once per year, while taking into account all antimicrobial test results.</p>

<p>The <code>key_antibiotics()</code> function is context-aware. This means that then the <code>x</code> argument can be left blank, see <em>Examples</em>.</p>
|
||||
<p>The function <code>key_antibiotics()</code> returns a character vector with 12 antibiotic results for every isolate. These isolates can then be compared using <code>key_antibiotics_equal()</code>, to check if two isolates have generally the same antibiogram. Missing and invalid values are replaced with a dot (<code>"."</code>) by <code>key_antibiotics()</code> and ignored by <code>key_antibiotics_equal()</code>.</p>
|
||||
<p>The <code><a href='first_isolate.html'>first_isolate()</a></code> function only uses this function on the same microbial species from the same patient. Using this, e.g. an MRSA will be included after a susceptible <em>S. aureus</em> (MSSA) is found within the same patient episode. Without key antibiotic comparison it would not. See <code><a href='first_isolate.html'>first_isolate()</a></code> for more info.</p>

<p>The <code>key_antimicrobials()</code> and <code>all_antimicrobials()</code> functions are context-aware. This means that then the <code>x</code> argument can be left blank, see <em>Examples</em>.</p>

<p>The function <code>key_antimicrobials()</code> returns a character vector with 12 antimicrobial results for every isolate. The function <code>all_antimicrobials()</code> returns a character vector with all antimicrobial results for every isolate. These vectors can then be compared using <code>antimicrobials_equal()</code>, to check if two isolates have generally the same antibiogram. Missing and invalid values are replaced with a dot (<code>"."</code>) by <code>key_antimicrobials()</code> and ignored by <code>antimicrobials_equal()</code>.</p>

The <a href='lifecycle.html'>lifecycle</a> of this function is <strong>stable</strong>. 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.</p>
|
||||
<p>If the unlying code needs breaking changes, they will occur gradually. For example, a 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.</p>

<p>There are two ways to determine whether isolates can be included as first weighted isolates which will give generally the same results:</p><ol>
|
||||
<li><p>Using <code>type = "keyantibiotics"</code> and argument <code>ignore_I</code></p>
|
||||
<p>Any difference from S to R (or vice versa) will (re)select an isolate as a first weighted isolate. With <code>ignore_I = FALSE</code>, also differences from I to S|R (or vice versa) will lead to this. This is a reliable method and 30-35 times faster than method 2. Read more about this in the <code>key_antibiotics()</code> function.</p></li>
|
||||
<li><p>Using <code>type = "points"</code> and argument <code>points_threshold</code></p>
|
||||
<p>A difference from I to S|R (or vice versa) means 0.5 points, a difference from S to R (or vice versa) means 1 point. When the sum of points exceeds <code>points_threshold</code>, which defaults to <code>2</code>, an isolate will be (re)selected as a first weighted isolate.</p></li>

To conduct epidemiological analyses on antimicrobial resistance data, only so-called first isolates should be included to prevent overestimation and underestimation of antimicrobial resistance. Different algorithms can be used to do so, see below.
|
||||
|
||||
These functions are context-aware. This means that then the \code{x} argument can be left blank, see \emph{Examples}.
|
||||
|
||||
The \code{\link[=first_isolate]{first_isolate()}} function is a wrapper around the \code{\link[=is_new_episode]{is_new_episode()}} function, but more efficient for data sets containing microorganism codes or names.
|
||||
|
||||
All isolates with a microbial ID of \code{NA} will be excluded as first isolate.
|
||||
\subsection{Why this is so Important}{
|
||||
\subsection{Different algorithms}{
|
||||
|
||||
To conduct an analysis of antimicrobial resistance, you should only include the first isolate of every patient per episode \href{https://pubmed.ncbi.nlm.nih.gov/17304462/}{(Hindler \emph{et al.} 2007)}. If you would not do this, you could easily get an overestimate or underestimate of the resistance of an antibiotic. Imagine that a patient was admitted with an MRSA and that it was found in 5 different blood cultures the following week. The resistance percentage of oxacillin of all \emph{S. aureus} isolates would be overestimated, because you included this MRSA more than once. It would be \href{https://en.wikipedia.org/wiki/Selection_bias}{selection bias}.
|
||||
According to Hindler \emph{et al.} (2007, \doi{10.1086/511864}), there are different algorithms to select first isolates with increasing reliability: isolate-based, patient-based, episode-based and phenotype-based. All algorithms select on a combination of the taxonomic genus and species (not subspecies).
|
||||

|

|

The functions \code{\link[=filter_first_isolate]{filter_first_isolate()}} and \code{\link[=filter_first_weighted_isolate]{filter_first_weighted_isolate()}} are helper functions to quickly filter on first isolates.
|
||||
|

The function \code{\link[=filter_first_isolate]{filter_first_isolate()}} is essentially equal to either:\preformatted{ x[first_isolate(x, ...), ]
|
||||

x \%>\% filter(first_isolate(...))
|
||||
This algorithm does not require any selection, as all isolates should be included. It does, however, respect all arguments set in the \code{\link[=first_isolate]{first_isolate()}} function. For example, the default setting for \code{include_unknown} (\code{FALSE}) will omit selection of rows without a microbial ID.

\section{Key Antibiotics}{
|
||||
\subsection{Patient-based}{
|
||||
|
||||
There are two ways to determine whether isolates can be included as first weighted isolates which will give generally the same results:
|
||||
To include every genus-species combination per patient once, set the \code{episode_days} to \code{Inf}. Although often inappropriate, this algorithm makes sure that no duplicate isolates are selected from the same patient.
|
||||
}
|
||||
|
||||
\subsection{Episode-based}{
|
||||
|
||||
To include every genus-species combination per patient episode once, set the \code{episode_days} to a sensible number of days. Depending on the type of analysis, this could be 14, 30, 60 or 365. Short episodes are common for analysing specific hospital or ward data, long episodes are common for analysing regional and national data.
|
||||
|
||||
This is the most common algorithm to correct for duplicate isolates. Patients are categorised into episodes based on their ID and dates (e.g., the date of specimen receipt or laboratory result). While this is a common algorithm, it does not take into account antimicrobial test results. This means that e.g. a methicillin-resistant \emph{Staphylococcus aureus} (MRSA) isolate cannot be differentiated from a wildtype \emph{Staphylococcus aureus} isolate.
|
||||
}
|
||||
|
||||
\subsection{Phenotype-based}{
|
||||
|
||||
This is a more reliable algorithm, since it also \emph{weighs} the antibiogram (antimicrobial test results) yielding so-called 'first weighted isolates'. There are two different methods to weigh the antibiogram:
|
||||
\enumerate{
|
||||
\item Using \code{type = "keyantibiotics"} and argument \code{ignore_I}
|
||||
|
||||
Any difference from S to R (or vice versa) will (re)select an isolate as a first weighted isolate. With \code{ignore_I = FALSE}, also differences from I to S|R (or vice versa) will lead to this. This is a reliable method and 30-35 times faster than method 2. Read more about this in the \code{\link[=key_antibiotics]{key_antibiotics()}} function.
|
||||
\item Using \code{type = "points"} and argument \code{points_threshold}
|
||||
|
||||
A difference from I to S|R (or vice versa) means 0.5 points, a difference from S to R (or vice versa) means 1 point. When the sum of points exceeds \code{points_threshold}, which defaults to \code{2}, an isolate will be (re)selected as a first weighted isolate.
|
||||
}
|
||||
This method weighs \emph{all} antimicrobial agents available in the data set. Any difference from I to S or R (or vice versa) counts as 0.5 points, a difference from S to R (or vice versa) counts as 1 point. When the sum of points exceeds \code{points_threshold}, which defaults to \code{2}, an isolate will be selected as a first weighted isolate.
|
||||
|
||||
All antimicrobials are internally selected using the \code{\link[=all_antimicrobials]{all_antimicrobials()}} function. The output of this function does not need to be passed to the \code{\link[=first_isolate]{first_isolate()}} function.
|
||||
\item Using \code{type = "keyantimicrobials"} and argument \code{ignore_I}
|
||||
|
||||
This method only weighs specific antimicrobial agents, called \emph{key antimicrobials}. Any difference from S to R (or vice versa) in these key antimicrobials will select an isolate as a first weighted isolate. With \code{ignore_I = FALSE}, also differences from I to S or R (or vice versa) will lead to this.
|
||||
|
||||
Key antimicrobials are internally selected using the \code{\link[=key_antimicrobials]{key_antimicrobials()}} function, but can also be added manually as a variable to the data and set in the \code{col_keyantimicrobials} argument. Another option is to pass the output of the \code{\link[=key_antimicrobials]{key_antimicrobials()}} function directly to the \code{col_keyantimicrobials} argument.
|
||||
}
|
||||
|
||||
The default algorithm is phenotype-based (using \code{type = "points"}) and episode-based (using \code{episode_days = 365}). This makes sure that every genus-species combination is selected per patient once per year, while taking into account all antimicrobial test results.

The \code{\link[=key_antibiotics]{key_antibiotics()}} function is context-aware. This means that then the \code{x} argument can be left blank, see \emph{Examples}.
|
||||
|
||||
The function \code{\link[=key_antibiotics]{key_antibiotics()}} returns a character vector with 12 antibiotic results for every isolate. These isolates can then be compared using \code{\link[=key_antibiotics_equal]{key_antibiotics_equal()}}, to check if two isolates have generally the same antibiogram. Missing and invalid values are replaced with a dot (\code{"."}) by \code{\link[=key_antibiotics]{key_antibiotics()}} and ignored by \code{\link[=key_antibiotics_equal]{key_antibiotics_equal()}}.
|
||||
|
||||
The \code{\link[=first_isolate]{first_isolate()}} function only uses this function on the same microbial species from the same patient. Using this, e.g. an MRSA will be included after a susceptible \emph{S. aureus} (MSSA) is found within the same patient episode. Without key antibiotic comparison it would not. See \code{\link[=first_isolate]{first_isolate()}} for more info.

The \link[=lifecycle]{lifecycle} of this function is \strong{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, a 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.

|

\section{Key Antibiotics}{
|
||||
|
||||
There are two ways to determine whether isolates can be included as first weighted isolates which will give generally the same results:
|
||||
\enumerate{
|
||||
\item Using \code{type = "keyantibiotics"} and argument \code{ignore_I}
|
||||
|
||||
Any difference from S to R (or vice versa) will (re)select an isolate as a first weighted isolate. With \code{ignore_I = FALSE}, also differences from I to S|R (or vice versa) will lead to this. This is a reliable method and 30-35 times faster than method 2. Read more about this in the \code{\link[=key_antibiotics]{key_antibiotics()}} function.
|
||||
\item Using \code{type = "points"} and argument \code{points_threshold}
|
||||
|
||||
A difference from I to S|R (or vice versa) means 0.5 points, a difference from S to R (or vice versa) means 1 point. When the sum of points exceeds \code{points_threshold}, which defaults to \code{2}, an isolate will be (re)selected as a first weighted isolate.
