Yоu hаve been аsked tо cоmpаre a new automated susceptibility test system (AST) to a gold-reference standard. The goal of your study is to evaluate the new automated AST platform using a well-characterized collection of gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa). You will compare the minimum inhibitory concentration (MIC) values obtained with the new method versus gold-standard broth microdilution. In review of the procedure, you read that during the comparison study, you will evaluate Categorical Agreement, which are the error rates calculated for each strain-antibiotic combination. An MIC >=2 discrepancy between the new method and the reference standard is considered a Categorical Error. Categorical Errors are described as: mE: “minor error” when disagreement of interpretations includes an “intermediate” interpretation by the reference standard or the comparator method ME: “major error” when a susceptible isolate is misinterpreted as resistant VME: “very major error” when a resistant isolate is misinterpreted as susceptible as compared to the reference standard/comparator method How would you interpret Categorical Agreement of the results, below (Escherichia coli AST new method versus gold standard)?
