Changing Use of Antibiotics in Community-Based Outpatient Practice, 1991–1999

Figure 2. Overall use of antibiotics decreased in pediatric visits for the common cold and unspecified upper respiratory tract
infections ( s) ( < 0.001) and for pharyngitis ( = 0.002). Among children receiving an antibiotic, broad-spectrum agents made
up an increased proportion of antibiotic prescriptions for each condition shown (for values, see text). (Results are shown
at the level of the patient visit: Broad spectrum indicates visits involving at least one broad-spectrum antibiotic; narrow
spectrum indicates visits involving only narrow-spectrum agents.) The mean number of visits occurring annually during the
study period is shown for each condition.
