< p > Of course, we cannot instantly provide you with knowledge and
experience. But with this < code > AMR< / code > package, we aimed at
providing (1) tools to simplify antimicrobial resistance data cleaning,
transformation and analysis, (2) methods to easily incorporate
international guidelines and (3) scientifically reliable reference data,
including the requirements mentioned above.< / p >
< p > The < code > AMR< / code > package enables standardised and reproducible
AMR data analysis, with the application of evidence-based rules,
determination of first isolates, translation of various codes for
microorganisms and antimicrobial agents, determination of (multi-drug)
resistant microorganisms, and calculation of antimicrobial resistance,
prevalence and future trends.< / p >

< p > As with many uses in R, we need some additional packages for AMR data
analysis. Our package works closely together with the < a href = "https://www.tidyverse.org" class = "external-link" > tidyverse packages< / a > < a href = "https://dplyr.tidyverse.org/" class = "external-link" > < code > dplyr< / code > < / a > and < a href = "https://ggplot2.tidyverse.org" class = "external-link" > < code > ggplot2< / code > < / a > by
RStudio. The tidyverse tremendously improves the way we conduct data
science - it allows for a very natural way of writing syntaxes and
creating beautiful plots in R.< / p >
< p > We will also use the < code > cleaner< / code > package, that can be used
for cleaning data and creating frequency tables.< / p >

isolate of every patient per episode< / a > (Hindler < em > et al.< / em > , Clin
Infect Dis. 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 weeks (yes, some countries
like the Netherlands have these blood drawing policies). The resistance
percentage of oxacillin of all isolates would be overestimated, because
you included this MRSA more than once. It would clearly be < a href = "https://en.wikipedia.org/wiki/Selection_bias" class = "external-link" > selection
