A geospatial approach to identify patterns of antibiotic susceptibility at a neighborhood level in Wisconsin, United States.

The global threat of antimicrobial resistance (AMR) varies regionally. This study explores whether geospatial analysis and data visualization methods detect both clinically and statistically significant variations in antibiotic susceptibility rates at a neighborhood level. This observational multicenter geospatial study collected 10 years of patient-level antibiotic susceptibility data and patient addresses from three regionally distinct Wisconsin health systems (UW Health, Fort HealthCare, Marshfield Clinic Health System [MCHS]).

Geographic Mapping of Escherichia coli Susceptibility To Develop a Novel Clinical Decision Support Tool.

Antimicrobial resistance (AMR) varies regionally. This study longitudinally maps susceptibility leveraging Wisconsin antibiograms ( = 202) collected from 2009, 2013, and 2015 to inform the development of a novel clinical decision support tool. Spatial interpolation methods were tested with susceptibilities to create geographic AMR visualizations and to estimate susceptibility in areas without AMR data.
