Average Percentage of Prescriptions Redeemed

Redemption will be measured as the weekly usage of the interventions. Participants will receive an automatic notification after each delivery (or weekly for the usual care arm) and will be asked to confirm that they received their delivery/redeemed their prescription. If they do not initially confirm, they will receive two reminder notifications. Redemption will be measured as the percentage of all 12 deliveries/mobile market visits that are either confirmed via post on the usage survey.

Average Percentage of Fruit and Vegetables Used

Usage will be measured in the self-reported weekly text surveys that will ask participants approximately what percentage of the fruits and vegetables that they receive was used by someone in their household: all (coded as 100%), most (coded as 75%), about half (coded as 50%), some (coded as 25%) and none (coded as 0%). Answers from all completed surveys over 12 weeks will be averaged to get a percent of food usage for each participant.

Eligible Participants Who Were Interested in the Program

Program interest is defined as the percentage of the total eligible individuals that were referred to the program who were 1.) reachable for recruitment and 2.) did not decline participation via either opt-out letter or when contacted by researchers (those who declined prior to being provided detail on their assigned intervention).

Percent of Eligible Participants Enrolled

Program enrollment will be measured as the percentage of patients eligible and referred that decide to enroll. Patients who choose not to enroll will be asked to provide more information on why they do not want to enroll.

Health Status and Disease Risk

Health status and disease risk will be measured using one subscale of the RAND 36-Item Short Form Health Survey (SF-36): 1.) General health: 1 item with a 5-point Likert scale where 1 is excellent and 5 is poor; this is combined with the EQ-5D-5L survey, which consists of 2 pages: the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS).The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'.
