Personalized Patient Data and Behavioral Nudges to Improve Adherence to Chronic Cardiovascular Medications

Study Description
Brief Summary:
The study plans to learn if sending different text messages, serving as reminders or encouragement, may help patients take their medication more often if they have had trouble keeping up with their medicines.

Condition or disease Intervention/treatment Phase
Cardiovascular Diseases Adherence, Medication Medication Adherence Diabetes Mellitus Hypertension Hyperlipidemias Coronary Artery Disease Atrial Fibrillation Behavioral: Nudge Not Applicable

Detailed Description:

Background: Up to fifty percent of patients do not take their cardiovascular medications as prescribed resulting in increased morbidity, mortality, and healthcare costs. Mobile and digital technologies for health promotion and disease self-management offer an intriguing and as of yet untested opportunity to adapt behavioral 'nudges' using ubiquitous cell phone technology to facilitate medication adherence.

Objectives: Aim 1: Conduct a pragmatic patient-level randomized intervention across three health care systems (HCS) to improve adherence to chronic CV medications. The primary outcome will be medication adherence defined by the proportion of days covered (PDC) using pharmacy refill data. Secondary outcomes will include intermediate clinical measures (e.g., BP control), CV clinical events (e.g., hospitalizations), healthcare utilization, and costs. Aim 2: Evaluate the intervention using a mixed methods approach and applying the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. In addition, assess the context and implementation processes to inform local tailoring, adaptations and modifications, and eventual expansion of the intervention within the 3 HCS more broadly and nationally.

Setting: The study will be conducted within three HCS in metro Denver: VA Eastern Colorado Health Care System (VA), Denver Health and Hospital Authority, and UCHealth.

Study Design

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 5000 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: The study will be a pragmatic, randomized controlled study with four treatment arms. Once patients are identified through pharmacy refill data to have a 7-day gap in any prescribed CV medication refills, they will be randomized to one of four arms, described in Intervention below. Randomization will be stratified within each of the clinics, and within strata defined by number of other CV medication classes that are prescribed at randomization (1-4), using blocks of 4 patients to ensure balance within clinics over time. Thus, within each clinic and number of other medication stratum, each set of 4 consecutively enrolled subjects will be randomized to the four study arms. Treatments will be initiated immediately upon randomization, in response to the 7-day gap.

Arms and Interventions
Arm Intervention/treatment
No Intervention: Usual Care
This group will not receive an intervention. We have included a usual care group to demonstrate the impact of the text messaging interventions above and beyond usual care given that many prior medication adherence interventions have demonstrated small to negligible effects.
Experimental: Generic Nudge
A generic reminder text will be delivered to patients to refill their medication at days 1, 3, 5, 7 and 10 after they been labeled as non-adherent.
 Behavioral: Nudge
Interventions will include a variety of text messages aimed at improving medication adherence.
Experimental: Optimized nudge
An optimized nudge text will be delivered to patients to remind them to refill their medications at days 1, 3, 5, 7 and 10 after they have been labeled as non-adherent.
 Behavioral: Nudge
Interventions will include a variety of text messages aimed at improving medication adherence.
Experimental: Optimized nudge plus AI Chat Bot
An optimized nudge text will be delivered to patients to remind them to refill their medications at days 1 and 3 after they have been labeled as non-adherent. If the patient has not filled their medication on days 5 and 7, in addition to receiving an optimized nudge text, an AI will conduct interactive chat via a chat bot to assess barriers filling the medication as described in Aim 1 above. If they still have not filled the medication, they will receive another message on day 10.
 Behavioral: Nudge
Interventions will include a variety of text messages aimed at improving medication adherence.

Plan Description:

Data collected as part of this project will be released in accordance with standard data sharing policies and procedures. Data will be made available to the broader scientific community after results are published in peer-reviewed journals.

Prior to making this data available, data will be redacted to strip identifiers and further de-identified by removing indirect identifiers that could lead to "deductive disclosure" of identities.

Due to the small numbers of participants in the qualitative interviews, we do not anticipate sharing raw data from individuals.

The agreement will prohibit the recipient from transferring the data to other users, require that the data's security be protected by standard means and be used for research purposes only. After a requestor completes the data-sharing agreement, we will either mail a CD with a limited dataset to the requestor, or email the data through our secure email system that requires users to create an account to receive sensitive data.
Supporting Materials: Study Protocol
Supporting Materials: Statistical Analysis Plan (SAP)

Time Frame: Data will be shared in a timely manner, as requested.
Access Criteria: The study team will share technical and practical knowledge regarding the creation of the chat bot and text messaging intervention, upon request. Further, the study team would readily share all data collection instruments and assessment algorithms used in the project to qualified individuals within the scientific community with the agreement that they will appropriately acknowledge the study team who developed the instruments.
