Testing the Impact of Pre-visit Priming as a Mechanism Across Multiple Medication Use Behavioral Targets in Primary Care Practice

We will use EHR data to identify eligible patients at BWH primary care clinics. Patients will be eligible if they have an upcoming primary care provider (PCP) appointment at an included BWH clinic, are ≥65 years, and are eligible for a medication target; exclusion criteria will include relevant EHR-documented allergies. After sharing patients with PCPs for potential opt-out, patients will be randomized 1:1 in REDCap® to intervention or usual care (no prompt). The intervention will include a pre-visit patient-facing prompt with information about the evidence-based medication target. If patients are eligible for multiple targets, one will be randomly selected. The primary clinical outcome will be measured on the day of the PCP visit using EHR data, depending on target: a) discontinuation or tapering order, or b) prescribing. Secondary outcomes will include a) these same measures in a 60-day follow-up period after the visit to capture any follow-up actions. We will use an intention-to-treat approach including patients regardless of whether the visit occurred. We plan to conduct the trial until 1700 patients are reached. We will also conduct exploratory mediation analyses of mechanisms through brief patient surveys with behavioral scales and PCP survey.
