The Shorter Is Better movement: past, present, future.

Experts have written that medical practice takes 10 to 20 years to evolve based on new data [1]. Right on cue, the Shorter Is Better movement is poised to transform clinical practice, 14 years after it was first elaborated [2], and 6 years after it was branded [3]. In the intervening period, many dozens of randomized controlled trials (RCTs) have reaffirmed the similar efficacy and superior safety of shorter courses of antibiotic regimens for many types of bacterial infections [4–6].
