Infectious diagnoses = viral upper respiratory tract infection, pharyngitis, otitis media, sinusitis, pneumonia, abscess, skin/soft tissue infection, or urinary tract infection. All other diagnoses were considered noninfectious. (A) Encounter number, diagnosis type, and antibiotic prescription rate throughout the study period. Dark gray bars are number of encounters with infectious diagnoses, and striped bars are number of encounters with noninfectious diagnoses. Percent of encounters with an antibiotic prescribed is shown in the black line. Dashed line represents interrupted time series analysis trend line for percent of encounters with an antibiotic prescription in P1 and P2, respectively. P-value comparing slope in P1 vs P2 = 0.03. (B) Percent of encounters per week by specific diagnosis. Abbreviations: P1, pre-pandemic (March 1, 2019–May 15, 2019); P2, early pandemic (March 1, 2020–May 15, 2020), represented by the gray shaded area.
