Change in proportion of patients that receive a vaccine recommendationDay 1, Day 30, Day 60, Day 90

Proportion of patients that receive a vaccine recommendation = multiplication of the answer to the following two items: (1) "I (will) check(ed) whether a patient has/had gotten all indicated vaccines", (2) "If I saw/see a patient had not gotten an indicated vaccine, I (will) discuss(ed) getting it."

Change in self-reported utilization of AIMSDay 1, Day 30, Day 60, Day 90

Composite score of the following items: (1) "I used/will use direct, declarative language, like: "You're due for your flu shot.
