MDR – multidrug-resistant
Data are collected from all infection work-ups (e.g., wound and blood cultures) among wounded personnel who were transferred from Landstuhl Regional Medical Center (LRMC) to a TIDOS-participating US military treatment facility (MTF) at all levels of care (LRMC and/or U.S. military treatment facilities). Patients often have serially positive cultures; however, an organism was counted only once per patient. An organism was counted at MDR if it was MDR at any time isolated during repeated isolation.
Only the top five organisms are reported. Total incorporates all organisms collected during infection workups, so it will be more than the sum of the listed organisms.
