Social Engagement Strategies to Improve Medication Adherence

Study Overview
=================
Brief Summary
-----------------
In this pilot study, investigators, in partnership with Resource Centers for Minority Aging Research (RCMAR) mentorship team and the MyMeds program, will enroll patients from MyMeds with diabetes, atherosclerotic cardiovascular disease, or congestive heart failure with poor medication adherence (medication adherence percentage<80% for statin or antihypertensive therapy) who report having a least one loved one or friend (e.g., spouse) whom they consider to be invested in their health, and with whom they would be willing to share focused medical information about medication adherence in the form of text messages. Participants will be randomized into either a private feedback arm or social network arm. In the private feedback arm, participants will only receive private consultations from a pharmacist regarding their medication adherence rates. In the social network arm, participants and their chosen loved one or friend will receive bi-weekly feedback text messages regarding the participant's medication adherence. Investigators will evaluate the effects of this social network intervention on medication adherence and examine the program's acceptability among study participants. This proposal is innovative because it leverages social networks-largely unused in medical care-for health improvement.

Detailed Description
-----------------
MyMeds (Managing Your Medication for Education and Daily Support) is an innovative care improvement program that embeds pharmacists into 27 University of California, Los Angeles (UCLA) primary care practices with the goals of (1) simplifying and reconciling medication regimens; (2) identifying strategies to improve adherence; and (3) reducing patient costs with generic substitutions and drug assistance programs. This program targets complex older adults and adults with poorly-controlled diabetes of all ages, and has reached more than 7,000 patients since its implementation in 2012. In an evaluation of over 700 older adults (≥65 years-old) who received a MyMeds consultation, investigators showed that the program reduced hospitalizations. In another evaluation that included adults of all ages, investigators showed that MyMeds reduced emergency department use (21%), systolic blood pressure (4 mmHg), and HbA1c (0.8%). However, a major underused resource in efforts to improve the health of complex adults targeted by MyMeds is their social network. Social networks are cost-free and highly influential social relationships and interactions that influence behavior and conversely are influenced by a patient's behavior. Patients spend vastly more time interacting within their social networks than they do interacting with healthcare providers, and patients often share health information with supportive members of their social network. These interactions, which are often substantial in quantity, could be designed to beneficially influence a patient's ability to create and sustain healthy behavior change. Medication nonadherence, in particular, increases morbidity, mortality, and healthcare costs in patients with chronic disease, but the private (rather than public) nature of taking medications limits the exposure of medication nonadherence to influence from the social network. An appropriately designed social network intervention can shift the dynamic, and MyMeds is an ideal setting for this type of intervention because it has robust infrastructure for identifying eligible patients, enrolling them in a pilot study, and measuring outcomes. In this pilot study, investigators, in partnership with RCMAR mentorship team and the MyMeds program, will enroll patients from MyMeds with diabetes, atherosclerotic cardiovascular disease, or congestive heart failure with poor medication adherence (medication adherence percentage<80% for statin or antihypertensive therapy) who report having a least one loved one or friend (e.g., spouse) whom they consider to be invested in their health, and with whom they would be willing to share focused medical information about medication adherence in the form of text messages. Participants will be randomized into either a private feedback arm or social network arm. In the private feedback arm, participants will only receive private consultations from a pharmacist regarding their medication adherence rates. In the social network arm, participants and their chosen loved one or friend will receive bi-weekly feedback text messages regarding the participant's medication adherence. Investigators will evaluate the effects of this social network intervention on medication adherence and examine the program's acceptability among study participants. This proposal is innovative because it leverages social networks-largely unused in medical care-for health improvement.

Design Details

Primary Purpose: Supportive Care
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: The intervention will enroll 70 patients over a 6-month period. Investigators will provide each patient with a smart pill bottle to sync medication use data with their phones and provide real-time data about adherence to study staff. After completing a baseline survey, investigators will confirm eligibility (including confirmation of loved ones' willingness to receive text messages), and randomize eligible patients to one of the two study arms. With synced data from the smart pill box, investigators will provide biweekly feedback about adherence in the form of a brief text message, including a comparison to the patient's adherence in the preceding week. Biweekly feedback will be provided for 12 weeks and semi-structured interviews will be performed among a random subsample of participants afterward.
Masking: None (Open Label)


Arms and Interventions

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Medication Adherence Rate | Rate at which participant is taking their medication. Outcome would be measured bi-weekly using a smart pill bottle and syncing data using blue-tooth capable phones. | 2 weeks, 4 weeks, 6 week, 8 weeks, 10 weeks, and 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Quality of Life measured by PROMIS-29 | Assessed using PROMIS-29 survey. | Baseline, 12 weeks | 
| Use of Technology for Health assessed by a short questionnaire | Patients will be asked whether they use tablets, smartphones, or other mobile technology. | Baseline | 
| Change of diet composition assessed by a dietary questionnaire | A short dietary questionnaire will be used to assess fruit, vegetable, fat, fiber, and sweetened beverage intake. For pragmatic reasons, longer food frequency questionnaire and 24 hour dietary recalls will be avoided because they may be too time consuming to complete. | Baseline, 12 weeks | 
| Change of physical activity assessed using items from IPAQ-S | Investigators will measure frequency, duration and intensity of patient's physical activity using items from the International Physical Activity Questionnaire short form (IPAQ-S). | Baseline, 12 weeks | 
| Change of depressive symptoms assessed using CES-D survey | Investigators will measure depressive symptoms using the CES-D, a validated scale based on the diagnostic criteria for major depressive disorder. | Baseline, 12 weeks | 
| Change of medical history assessed using NHANES survey | Investigators will use questions from the NHANES | Baseline, 12 weeks | 
| Change of smoking behavior assessed using the California Tobacco Survey | Investigators will use measures adapted from the California Tobacco Survey. During follow-up, investigators will ask about smoking cessation, quit attempts, reduction in daily | Baseline, 12 weeks | 
| Change of self-efficacy and motivation assessed using PAM instrument | Investigators will assess self-efficacy, outcome expectancy, motivation, and patient activation. Patient activation will be assessed with the Patient Activation Measure (PAM) (see Reddy et al, JGIM 2017) | Baseline, 12 weeks | 
| Change of social support usages assessed by MSPSS instrument | Investigators will measure social support with the Multidimensional Scale of Perceived Social Support (MSPSS) instrument. | Baseline, 12 Weeks | 
| Program Acceptability assessed by a random sub-sample of interviews | After the 12-week period, a random sub-sample of participants from both arms will be interviewed to measure the study's acceptability. | 12-weeks |
