NCT02732847

Brief Summary

Delayed prescriptions have been shown to lower antibiotic use for upper respiratory tract infections (which are mostly viral). This trial will test the hypothesis that if the clinician post-dates the delayed prescription by 2 days, rather than dating it on the day the patient is seen, there will be a further drop in the rate of antibiotic use.
