Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

"No-shows," or missed visits are a persistent problem in all health care systems. They contribute to worsened patient access, longer wait times, and inefficient use limited health care resources. The VA's no-show rate has shown no improvement in years, resulting in a staggering 9 million ambulatory no-shows in Fiscal Year (FY) 2015. Appointment reminders are an essential and proven element to addressing no-shows but major research gaps exist. Behavioral economics (BE) and allied fields offer key insights that are relevant to developing innovation in the field of appointment reminders. Adding "nudges" informed by concepts such as social norms, behavioral intentions, clear instructions, and potential negative consequences to the Veteran and others is a novel but evidence-based way to create enhanced appointment reminders. Seemingly small changes to appointment letters can create measurable shifts in appointment attendance and no-shows. Even more, these behavioral nudges can produce large benefits when taken to scale and compounded across a population. This project will address several aims, including: developing BE-informed messages to incorporate into enhanced appointment reminders; evaluating the effect of several versions of enhanced appointment reminders; and identifying potential barriers and facilitators to widespread implementation of enhanced appointment reminder messages.
