Evaluating Covered California's Grocery Support Program

In 2024, Covered California initiated multiple Population Health Investments (PopHIs) based on funds collected by participating plans if they failed to meet a set of quality benchmarks related to diabetes control, blood pressure control, colorectal cancer screening, and childhood immunizations. One priority area for the PopHIs was food insecurity among patients who manage chronic diseases. Food insecurity, defined by the United States Department of Agriculture (USDA) as a "lack of access to enough food for an active, healthy life" effects 18% of newly enrolled Covered California members. Food insecurity is more pronounced and is associated with poor clinical outcomes and more avoidable and costly healthcare utilization among individuals who manage chronic disease. The burden of disease is high among Covered California members; for every 1,000 Covered California enrollees with one or more years of continuous enrollment, 390 have a chronic disease diagnosis. The goal of the proposed research is to evaluate the impact of a 12-month grocery support program on participant food insecurity and other outcomes compared to a single payment at the end of 12 months. Participants were invited to enroll in the program if they were active members of Covered California at the time of enrollment, and had 1) a documented chronic condition, 2) food insecurity measured using the validated two-item screener), and 3) an income at or below 250% of the FPL. Participants were randomly assigned to receive either an $80 reusable semi-restricted cash card re-loaded monthly for one year or a one-time cash card of $960 (payments in both arms adjusted based on household size). Retailers are restricted to food retailers, which includes retailers that do sell non-food goods. The study has four main data sources: survey data from surveys repeated at baseline and 12-months; cash card spending data; qualitative participant interview data and claims data. Specific Aims are to: Aim 1 - To evaluate the impact of the grocery support program on participant food insecurity and other dietary outcomes. H1: Participants who receive the monthly payment will have decreased rates of food insecurity and improved dietary outcomes 12-months after participating compared to participants who do not receive the monthly payment. Aim 2 - To assess the impact of the grocery support program on self-rated health, healthcare experiences, and social risks and other quality of life measures. H1: Participants who receive the monthly payment will have improved self-rated health, healthcare experiences, and quality of life, and fewer social risks compared to participants who do not receive the monthly payment. Aim 3 - To analyze the impact of the grocery support program on participant's health utilization and outcomes. H1: Relative to participants who do not receive the monthly payment, Grocery Support Program participants will have fewer hospitalizations and Emergency Department (ED) visits and more primary care visits. H2: Relative to participants who do not receive the monthly payment, Grocery Support Program participants will have greater improvements in chronic disease clinical outcomes.
