Fig. 2.
Trends over time in testing for carbapenemase genes among cultures that grew carbapenemase-producing carbapenem-resistant Enterobacterales (CP-CRE). The orange line indicates the percentage of CP-CRE cultures that were subsequently tested for at least 1 genetic mechanism of resistance, and the colored bars reflect the number of CP-CRE cultures with evidence of testing for each specific gene. The green arrow indicates the publication of updated VA guidelines (in early 2017) requiring PCR testing for carbapenemases among suspected CP-CRE isolates.
