Abstract
Antibiotic selection has become complicated. Gone are the days when you only needed to search a small book, such as the Sanford Guide to Antimicrobial Therapy [ 1], to find the appropriate antibiotic. Today, the right antibiotic may depend on your patient, other patients in the vicinity of your patient, your patient's insurance, your hospital, your hospital's formulary, your city, the time of year, and many other factors [ 2–6]. Some antimicrobial decisions require one to serve as part physician, part epidemiologist, part economist, part pharmacist, part historian, and part sociologist. With limited time in which to see each patient and to make decisions, juggling all of these roles is challenging for even the most multitalented physicians.
