Preventive Reminder Ordering AssistanCe Via Texting for Improved Visit Encounters

A substantial portion of the United States population remains overdue for preventive care screenings, despite availability of health services. This gap in care persists due to both patient and clinician facing barriers. Patients may not always remain actively engaged with their care team, while clinicians are impacted by time constraints and the complexity of managing multiple care tasks during visits. One population health strategy to address these barriers is visit-based nudges, which is anchored around office visits and uses methods such as pre-visit texting to patients and pended orders for clinicians. In a previous study aimed at improving influenza vaccination rates, pre-visit texting and automated pended orders used within an office visit increased vaccination rates by 5 percentage points. Another prior study, aimed at improving mammogram completion, utilized pended orders and post-visit texting to increase screening rates by 5 percentage points at six months for intervention patients. Both studies have demonstrated the impact of leveraging multiple nudges to both patients and clinicians and have highlighted the need to integrate these aspects into one large scalable program to create a cohesive patient experience. Building upon our prior work and in collaboration with primary care, we propose to develop and evaluate an integrated visit-based preventive health program with nudges to both clinicians and patients using a stepped wedge design, with the goal of implementing this system across primary care practices.

Inclusion criteria

All patients must meet the following criteria to be eligible:

• 18 years or older
• A scheduled new or return (non-urgent/sick) primary care visit at one of the study practices
• Overdue for at least one of the included care gaps according to Health Maintenance: Mammogram, DEXA, Hemoglobin A1C, Basic Metabolic Panel, Urine Microalbumin, Lipids, Hepatitis C
• Last eligible office visit was greater than or equal to 3 months ago

Exclusion criteria

As this trial is integrated with routine clinical operations, there will be no exclusion criteria. However, for each care gap independently, we will exclude all patient visits throughout the remaining trial duration after the patient's first eligible office visit within the trial duration. In other words, each patient will contribute data from at most one eligible office visit.
