Data set containing clinical breakpoints to interpret MIC and disk diffusion to SIR values, according to international guidelines. Currently implemented guidelines are EUCAST (2011-2023) and CLSI (2011-2023). Use as.sir()
to transform MICs or disks measurements to SIR values.
Format
A tibble with 42 599 observations and 12 variables:
guideline
Name of the guidelinemethod
Either "DISK" or "MIC"site
Body site, e.g. "Oral" or "Respiratory"mo
Microbial ID, seeas.mo()
rank_index
Taxonomic rank index ofmo
from 1 (subspecies/infraspecies) to 5 (unknown microorganism)ab
Antibiotic ID, seeas.ab()
ref_tbl
Info about where the guideline rule can be founddisk_dose
Dose of the used disk diffusion methodbreakpoint_S
Lowest MIC value or highest number of millimetres that leads to "S"breakpoint_R
Highest MIC value or lowest number of millimetres that leads to "R"ecoff
Epidemiological cut-off (ECOFF) value, used in antimicrobial susceptibility testing to differentiate between wild-type and non-wild-type strains of bacteria or fungi (useas.sir(..., ecoff = TRUE)
to interpret raw data using ECOFF values)uti
A logical value (TRUE
/FALSE
) to indicate whether the rule applies to a urinary tract infection (UTI)
Details
Clinical breakpoints are validated through WHONET, a free desktop Windows application developed and supported by the WHO Collaborating Centre for Surveillance of Antimicrobial Resistance. More can be read on their website.
Like all data sets in this package, this data set is publicly available for download in the following formats: R, MS Excel, Apache Feather, Apache Parquet, SPSS, SAS, and Stata. Please visit our website for the download links. The actual files are of course available on our GitHub repository.
They allow for machine reading EUCAST and CLSI guidelines, which is almost impossible with the MS Excel and PDF files distributed by EUCAST and CLSI.
