About this study

Official title: Sequential Multiple Assignment Randomized Trial to Reduce Food Insecurity and Improve Adherence in Patients With Hypertension

Food insecurity affects 20% of the 116 million people in the US with hypertension and is associated with poor adherence to evidence-based treatments and disparities in hypertension outcomes. Interventions are being used to address food insecurity in clinical care settings, but people differ in the support they need to reduce food insecurity and little is known about which food insecurity interventions work best, or for whom. The goal of this study is to develop and test an adaptive food insecurity intervention using a Sequential Multiple Assignment Randomized Trial to determine which initial food insecurity intervention is more effective in improving adherence and blood pressure in patients with hypertension and for those who do not respond to the initial intervention, evaluate how to best provide additional support.

Read the detailed description

In the US, 47% of adults have hypertension (HTN), and HTN is the leading cause of cardiovascular disease morbidity and mortality. Uncontrolled HTN increases the risk of cardiovascular disease, chronic kidney disease, and cognitive impairment. Current guidelines recommend the adoption of a healthy diet as an integral part of ongoing treatment regardless of the underlying antihypertensive drug treatment. The Dietary Approaches to Stop Hypertension (DASH) eating pattern is a diet rich in fruits, vegetables, and whole grains with a reduced content of sodium and saturated fat. The DASH is the diet with the strongest evidence to be effective for lowering blood pressure. Despite the evidence base for the effectiveness of DASH as well as pharmacological treatments, economic factors are common barriers to individuals with HTN adhering to treatments. Adherence is multidimensional and involves initiation, implementation, and persistence. Food insecurity (FI), the lack of consistent access to the food needed for a healthy life, is an important factor that leads to HTN disparities. Individuals living in food insecure households are less likely to adhere to prescribed HTN treatments, such as DASH and medications, and more likely to have worse blood pressure control.

Because of the prevalence of FI and associated poor health outcomes, a growing number of health systems and health insurers are investing in integrating interventions to address FI as part of routine clinical care. These interventions include 1) providing information to patients about community resources), 2) utilizing community health workers (CHW), and 3) home delivery of medically tailored meals (MTM). Studies have shown these FI interventions have varying levels of success on improving food security and health. However, people often need varying levels of support to address needs, and, rather than using only one single intervention to address FI, there remains a gap in understanding whether adaptively allocating resources based on need has the potential to more effectively, equitably, and efficiently improve food security and health for a greater proportion of patients.

To advance the science in patient adherence and blood pressure management, this study will conduct a sequential multiple assignment randomized trial (SMART) among food-insecure patients with uncontrolled HTN. SMART uses experimental design principles to determine whether and how to alter treatments to build optimal adaptive interventions. This study will assess the change in adherence and blood pressure over time (0-9 months). This study will also evaluate if treatment options were more effective for particular patients. Several other measures are included in this study to learn more about how an adaptive intervention designed to address FI affects blood pressure, adherence, food security, health-related quality of life, and other key risk factors for blood pressure control in patients with HTN.

The proposed Sequential Multiple Assignment Randomized Trial to reduce Food Insecurity and Improve Adherence in Patients with Hypertension (SMART-FI) is a single-site, open-label, longitudinal two-stage SMART. Participants will be randomized to one of two first-stage treatments for 3 months: 1) information about community resources or 2) in-person CHW support. Participants who do not have a 10mmHg improvement in systolic blood pressure (SBP) at 3 months will be re-randomized to one of two second-stage treatments for an additional 3 months: 1) CHW support or 2) home delivery of MTM. The study will recruit 224 participants for this trial. Participants will engage in the interventions up to 6 months and will be followed for a total of 9 months. In Aim 1, the study will determine which first-stage FI intervention is more effective in improving adherence and blood pressure. In Aim 2, the study will evaluate which FI intervention is the best next step for those who do not respond to the initial intervention. In Aim 3, the study will explore how, why, and under what circumstances participants achieved improvements to the first- and second-stage interventions by conducting semi-structured interviews with participants and evaluating for potential predictors of heterogeneity in response to each intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Systolic blood pressure value

    Systolic blood pressure measured as mmHg

    Measured: Month 9

  2. Diastolic blood pressure value

    Diastolic blood pressure measured as mmHg

    Measured: Month 9

  3. Dietary Approaches to Stop Hypertension (DASH) diet adherence Score

    Change in DASH diet adherence over time, based on the Mellen DASH diet adherence index - The Mellen DASH diet index is a nutrient-based method for assessing adherence to the Dietary Approaches to Stop Hypertension (DASH) diet. It uses nine key nutrients to determine a score ranging from 0 to 9, with 9 indicating the most adherence - Food items on the FFQ are assigned to 7 DASH food groups and 3 components using the Harvard nutrient database. Servings in each component are scored 0, 0.5, and 1. The DASH diet adherence score ranges from 0 to 10 and is the sum of the 10 component scores. Higher scores indicate greater diet concordance.

    Measured: Month 9

  4. Medication adherence Score

    Change in medication adherence based on the 12-item Adherence to Refills and Medications Scale - The 12-item Adherence to Refills and Medications Scale (ARMS) is a self-report questionnaire designed to measure a patient's adherence to medication regimens - Each scale comprises five items that are scored on a Likert-type scale, where 1 = strongly disagree, 2 = disagree, 3 = uncertain, 4 = agree and 5 = strongly agree. Higher scores indicate stronger beliefs in the necessity of medication and greater concerns about taking it.

    Measured: Month 9

  5. Food Security Score

    Change in food security over time based on the 10-item USDA Food Security Survey Module with a 30-day reference period - The USDA Food Security Survey Module (HFSSM) uses a 10-item adult-referenced module to assess food security status. A raw score is calculated based on affirmative responses to these 10 questions, and this score is then used to classify households into food security categories: high, marginal, low, or very low.

    High Food Security (Raw Score 0): No affirmative responses. Marginal Food Security (Raw Score 1-2): One or two affirmative responses. Low Food Security (Raw Score 3-5): Three to five affirmative responses. Very Low Food Security (Raw Score 6-10): Six to ten affirmative responses.

    Measured: Month 9

Secondary outcomes (2)
  1. Health-related quality of life Score

    Change in EQ-5D-5L scores - assigning a numerical value to each response level (i.e., 1 for "no problems", 5 for "extreme problems"/"unable to") and summing these values across the five items, resulting in a score from 5 (11,111, no problems on any dimension) to 25 (55,555, extreme problems on all dimensions)

    Measured: Month 9

  2. Number of Changes in Community resource Use

    Changes in use of community resources (e.g. food pantries, supplemental nutrition assistance program)

    Measured: Month 9
