Primary outcomes

  1. Change in proportion of patients that receive a vaccine recommendation

    Time frame: Day 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." Both items are answered on a scale from 0% (never) to 100% (always).

  2. Change in self-reported responsibility perception

    Time frame: Day 1, Day 30, Day 60, Day 90

    Self-reported responsibility perception = answer to the following item: (1) "Recommending indicated vaccines is within the scope of my professional responsibilities". This item is answered on a scale from 0% (completely disagree) to 100% (completely agree).

  3. Change in self-reported assessment of patient recommendation acceptance

    Time frame: Day 1, Day 30, Day 60, Day 90

    Self-reported assessment of patient recommendation acceptance = answer to the following item: (1) "If I recommend(ed) an indicated vaccine, my patient (will) accept(ed) that recommendation.". This item is answered on a scale from 0% (never) to 100% (always).

  4. Change in self-reported patient trust

    Time frame: Day 1, Day 30, Day 60, Day 90

    Self-reported patient trust = answer to the following item: (1) "Thinking about the last/next 30 days I provided care, I can say that my patients (will) trust(ed) me as their healthcare provider". This item is answered on a scale from 0% (completely disagree) to 100% (completely agree).

  5. Change in self-reported utilization of AIMS

    Time frame: Day 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. We'll do that at the end of this visit"; (2) "If the patient showed/shows hesitancy about getting vaccinated, I (will) ask(ed) about their concerns, and then use(d) active listening to understand their thoughts"; (3) "If the patient showed/shows hesitancy about getting vaccinated, I (will) listen(ed) to the patient's reasoning and then summarize(d) the patient's reasoning back to them to show that I understood/understand"; (4) "If the patient still has concerns, I did/will not continue efforts to convince them."

    Each item is answered on a scale from 0% (never) to 100% (always).

  6. Change in self-reported rate of patient vaccine uptake

    Time frame: Day 1, Day 30, Day 60, Day 90

    Answer to the following item: "Estimate what percentage of your patients is/will be fully vaccinated against […]" This item is answered on a scale from 0% to 100%.

    The question is being asked 8-10 times with the following name inserted for [...] in the above question:

    Flu COVID-19 Tetanus, Diphtheria, Pertussis HPV Hepatitis B Meningitis / Meningococcal Shingles Pneumococcal Other (which can be two other diseases that the respondent indicated)

Secondary outcomes

  1. Change in belief about patient autonomy

    Time frame: Day 1, Day 30, Day 60, Day 90

    Answer to the following item: "I stated / will state the patient's options - to vaccinate or not, and with which vaccine - so that they can make an informed decision." This item is answered on a scale from 0% to 100%.

  2. Change in proportion of patients that accept a recommendation

    Time frame: Day 1, Day 30, Day 60, Day 90

    Proportion of patients that accept a recommendation = multiplication of the answer to the following three 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."; (3) "If I recommend(ed) an indicated vaccine, my patient (will) accept(ed) that recommendation."
