Using a national antimicrobial susceptibility database, researchers compared annual and aggregated rates of AMR in community and tertiary care hospitals from 1999 to 2012 for multidrug-resistant Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, and Pseudomonas aeruginosa.
The study’s findings suggest that there was no significant overall variation in rates of AMR between TCHs and SCHs. While in inpatient settings, S. aureus, K. pneumoniae, A. baumannii were higher in SCHs, and S. aureus and P. aeruginosa were higher in TCH outpatient settings, after accounting for time trends and hospital-level variability, no significant variation had occurred.
Increasing trends among all pathogens, particularly E. coli, indicate a continued need to improve infection control and antimicrobial stewardship in all settings. A clear increasing trend of AMR in both settings and all pathogens was further confirmation of a growing national problem.
