<p>These functions are meant to count isolates. Use the <code><a href="proportion.html">resistance()</a></code>/<code><a href="proportion.html">susceptibility()</a></code> functions to calculate microbial resistance/susceptibility.</p>
<p>The function <code>count_resistant()</code> is equal to the function <code>count_R()</code>. The function <code>count_susceptible()</code> is equal to the function <code>count_SI()</code>.</p>
<p>The function <code>n_sir()</code> is an alias of <code>count_all()</code>. They can be used to count all available isolates, i.e. where all input antibiotics have an available result (S, I or R). Their use is equal to <code><a href="https://dplyr.tidyverse.org/reference/n_distinct.html" class="external-link">n_distinct()</a></code>. Their function is equal to <code>count_susceptible(...) + count_resistant(...)</code>.</p>
<p>The function <code>count_df()</code> takes any variable from <code>data</code> that has an <code><a href="as.sir.html">sir</a></code> class (created with <code><a href="as.sir.html">as.sir()</a></code>) and counts the number of S's, I's and R's. It also supports grouped variables. The function <code><a href="proportion.html">sir_df()</a></code> works exactly like <code>count_df()</code>, but adds the percentage of S, I and R.</p>

<h2 id="interpretation-of-sir">Interpretation of SIR<a class="anchor" aria-label="anchor" href="#interpretation-of-sir"></a></h2>
<p>In 2019, the European Committee on Antimicrobial Susceptibility Testing (EUCAST) has decided to change the definitions of susceptibility testing categories S, I, and R as shown below (<a href="https://www.eucast.org/newsiandr" class="external-link">https://www.eucast.org/newsiandr</a>):</p><ul><li><p><strong>S - Susceptible, standard dosing regimen</strong><br>
A microorganism is categorised as "Susceptible, standard dosing regimen", when there is a high likelihood of therapeutic success using a standard dosing regimen of the agent.</p></li>
<li><p><strong>I - Susceptible, increased exposure</strong> <em><br>
A microorganism is categorised as "Susceptible, Increased exposure</em>" when there is a high likelihood of therapeutic success because exposure to the agent is increased by adjusting the dosing regimen or by its concentration at the site of infection.</p></li>
<li><p><strong>R = Resistant</strong><br>
A microorganism is categorised as "Resistant" when there is a high likelihood of therapeutic failure even when there is increased exposure.</p><ul><li><p><em>Exposure</em> is a function of how the mode of administration, dose, dosing interval, infusion time, as well as distribution and excretion of the antimicrobial agent will influence the infecting organism at the site of infection.</p></li>
</ul></li>
</ul><p>This AMR package honours this insight. Use <code><a href="proportion.html">susceptibility()</a></code> (equal to <code><a href="proportion.html">proportion_SI()</a></code>) to determine antimicrobial susceptibility and <code>count_susceptible()</code> (equal to <code>count_SI()</code>) to count susceptible isolates.</p>

<h2 id="combination-therapy">Combination Therapy<a class="anchor" aria-label="anchor" href="#combination-therapy"></a></h2>
<p>When using more than one variable for <code>...</code> (= combination therapy), use <code>only_all_tested</code> to only count isolates that are tested for all antibiotics/variables that you test them for. See this example for two antibiotics, Drug A and Drug B, about how <code><a href="proportion.html">susceptibility()</a></code> works to calculate the %SI:</p>
