Reinforcement Learning in Diabetes Mellitus Trial (REINFORCE)
February 6, 2023 updated by: Julie Lauffenburger, Brigham and Women's Hospital
Optimizing Message Framing for Healthy Habits for Patients With Type 2 Diabetes - Phase II (Pragmatic Trial)
Reinforcement learning is an advanced analytic method that discovers each individual's pattern of responsiveness by observing their actions and then implements a personalized strategy to optimize individuals' behaviors using trial and error.
The goal of this pilot study is to develop and test a novel reinforcement learning-enhanced text messaging program to support medication adherence in patients with type 2 diabetes.
Type 2 diabetes is an optimal condition in which to test this program, as it is one of the most prevalent chronic conditions in the US adult population and requires most patients to be on daily or twice daily doses of medications.
This pilot study will be a parallel randomized pragmatic trial comparing medication adherence and clinical outcomes for adults aged 18-84 with type 2 diabetes who are prescribed 1-3 daily oral medications for this disease.
Participants will be randomized to one of two arms for the duration of the study period: (1) a reinforcement learning intervention arm with up to daily, tailored text messages based on time-varying treatment-response patterns; or (2) a control arm with up to daily, un-tailored text messages.
Our outcomes of interest will be medication adherence, as measured by electronic pill bottles, and HbA1c levels.

Arms and Interventions

Intervention / Treatment |
---|---|
EXPERIMENTAL: Reinforcement Learning Intervention Arm
Up to daily, tailored text messages.
|
Participants in the intervention arm will receive up to daily, tailored text messages based on their electronic pill bottle-measured adherence.
Given the participants' baseline characteristics and time-varying responses to the messages, a reinforcement learning algorithm will deliver different text messages and adapt over time to determine which type of messaging works best for each individual participant.
|
NO_INTERVENTION: Control Arm
Up to daily, untailored text messages.
