Penn Produce Prescription and Chronic Kidney Disease Study

The study team will conduct a two-arm 1:1 randomized controlled trial to examine the feasibility, acceptability, and likely effect of a produce prescription intervention on patient-centered outcomes, health behaviors and health outcomes, among food insecure adults with CKD stages 3-5. The study's specific aims are: Aim 1: Establish a community advisory board (CAB) to inform and guide the produce prescription intervention. The CAB will include patients, community members, CKD providers and relevant community partners. Aim 2: Evaluate the effectiveness of a produce prescription intervention on clinical and patient centered outcomes in a randomized trial among (n=100) people with CKD and food insecurity. People with CKD stages 3-5 and food insecurity will be randomized to either a control or intervention group, which will receive a twice monthly produce prescription voucher to purchase fruits and vegetables at local stores for 6 months. Participants will be followed for patient-centered outcomes (food and nutrition insecurity, health-related quality of life, depression, and anxiety) and clinical outcomes (diet quality, metabolic acidosis, serum albumin, estimated GFR, blood pressure, and HbA1c). The study's hypothesis is that participants receiving the intervention will have improvements in food and nutrition security, diet quality and other patient-centered outcomes compared to the control group. The CKD clinical outcomes are exploratory and will serve as a proof-of-concept for this type of intervention in a CKD population. Aim 3: Determine intervention acceptability and uptake and explore patient experiences with managing food insecurity and CKD. Researchers will administer surveys to eligible individuals who decline study enrollment (n=20), monitor self-report of voucher delivery and usage, and track voucher redemption rates to assess acceptability and uptake. Researchers will also conduct in-depth semi-structured interviews with participants in the intervention (n=20) and control (n=10) group to elucidate the experience of food insecurity and CKD co-management, coping strategies, and perceptions of the intervention.
