About this trial
The goal of the ADHERE-ASCVD study is to evaluate and optimize patient-facing messaging strategies to improve statin refill and adherence among adults with atherosclerotic cardiovascular disease (ASCVD) or diabetes.
The main questions it aims to answer are:
1. Do different outreach methods (such as text messages, secure portal messages, or email) increase short-term statin refill compared to usual care? 2. Among patients who do not initially refill their prescription, does changing the outreach method improve refill rates?
The team with operational partners will evaluate the comparitive effectivessness of multiple messaging strategies delivered through existing health system communication channels, including SMS (text messaging), secure patient portal messages, non-secure email, and usual care (no additional outreach).
Participants
* Receive an initial outreach message encouraging statin refill (or usual care) Be monitored for statin refill within 14 days * Potentially receive a second outreach message using the same or a different communication method if they do not initially refill their prescription * Have their medication refill patterns tracked over time, including longer-term adherence outcomes
