The Global Impact of Drug Resistance [PDF]

open access: yesClinical Infectious Diseases, 2003
Measuring the impact of drug resistance is an important step in understanding the scope of the problem and formulating policies to limit the emergence and spread of resistant organisms. Studies have focused on measuring the increased costs, morbidity, and mortality in patients with infections due to resistant versus susceptible organisms.
