Schematic for DOOR MAT. Red indicates selection of an antibiotic for which the target infection is deemed resistant (most undesirable). Green indicates selection of an antibiotic from the narrowest spectrum for which the target infection is deemed susceptible (most desirable). The shade of gray indicates selection of an antibiotic from spectrums for which the target infection is deemed susceptible but not the narrowest. Lighter shades of gray indicate more desirability—that is, closer to the most-desirable narrowest spectrum for which the target infection is deemed susceptible. Abbreviations: AST, antimicrobial susceptibility testing; DOOR MAT, Desirability of Outcome Ranking for the Management of Antimicrobial Therapy, R, Resistant; S, Susceptible.
