Clinicians within practices assigned to the Education/Feedback group received a personal email from one of the authors at the outset of the project explaining that the Committee on Infectious Diseases of the American Academy of Pediatrics (the "Red Book Committee") recommends limiting the duration of antibiotic treatment for uncomplicated CAP to 5 days and for uncomplicated SSTI to 5-7 days. The email also shared data on the performance of the individual PCC and their practice for CAP and SSTI for the baseline period and the goals for each-50% for CAP and 67% for SST. An infographic was also attached to the email which could be printed and displayed in the PCC's work area. One month and two months into the project period, each PCC in the Education/Feedback group received an email reminding them of the recommendations and updating them on their performance since the previous email.

Clinicians within practices assigned to the CDS group did not receive education or any performance feedback relative to the initiative. If they prescribed an antibiotic linked to a diagnosis of CAP with a duration of greater than 5 days, or to a diagnosis of SSTI with a duration greater than 7 days, they received a pop-up advisory when they attempted to sign the prescription alerting them to the relevant recommendation (eFigure 3). The alert was a "hard stop", meaning that the prescriber was required to respond in some way to continue their work. Options included altering the prescription to comply with the recommended duration or acknowledging the alert and sending the prescription with the originally selected duration.
