Since January 2019, the EUCAST clinical resistance breakpoint for azithromycin of MIC>0.5 mg/L has been replaced with an ECOFF of MIC>1 mg/L. Using also the EUCAST ECOFF, a significant increase in the proportion of isolates above this ECOFF was observed: from 3.7% in 2017 to 7.6% in 2018 (p<0.0002). In 2018, 24 countries

Epidemiologic Cutoff Values Epidemiologic cutoff values, abbreviated ECV (CLSI) or ECOFF (Eucast) , are measures of a drug MIC distribution that separate bacterial populations into those representative of a wild type population, and those with acquired or mutational resistance to the drug.

There are changes in the breakpoint tables every year. Some may be difficult to understand or accept without having followed the development of and consultations on the changing definitions of the susceptibility categories, especially the change from the old "intermediate" (I) to the new "Susceptible, increased exposure" (I). EUCAST is a standing committee jointly organized by ESCMID, ECDC and European national breakpoint committees. EUCAST was formed in 1997. It has been chaired by Ian Phillips (1997 - 2001), Gunnar Kahlmeter (2001 - 2012), Rafael Canton 2012 - 2016) and Christian Giske (2016 - ). The mic.eucast.org website is the EUCAST software for displaying distributions of MIC-values (generated with broth microdilution according to the ISO-standard or with methods calibrated to broth microdilution or when appropriate agar dilution) and inhibition zone diameters (generated only with EUCAST disk diffusion methodology with disks and media from several manufacturers).

For E. coli, the IMM ECOFFs were mostly similar to the EUCAST ECOFFs, with only minor differences (Δ = 1 mm), e.g., 19 mm versus 18 mm for cefuroxime. EUCAST also show cutoff values, ECOFF values, which were used as the reference.

A EUCAST Subcommittee is currently reviewing the rules for inclusionandexclusionofdata setsin aggregatedMICdistributions and the process by which ECOFF values are deﬁned. Contributors of MIC data are not informed about whetheror not their contributions … 2017-11-01 Background: EUCAST has revised the definition of the susceptibility category "I" from "Intermediate" to "Susceptible, Increased exposure". This implies that "I" can be used where the drug-concentration at the site of infection is high, either because of dose escalation or through other means to ensure efficacy. 2018-07-27 ECOFF is listed in the World's largest and most authoritative dictionary database of abbreviations and acronyms.

Additionally, WT-ULs were determined statistically using 97.5% and 99% endpoints and the EUCAST ECOFFinder program, and the previously described derivatization method, which provides a single ECOFF. 10 A consensus WT-UL was chosen taking into account the eyeball and statistical endpoints and the fact that some MIC distributions were slightly truncated to the left and therefore resulted in

In 2002, EUCAST launched the concept of gathering large numbers of MIC values to present as aggregated MIC distributions for each species-agent combination and to determine epidemiological cut-off values (ECOFF) on.
