Not Applicable

• Conditions: Food Insecurity
• Interventions: Behavioral: Enhanced Produce Prescription Implementation

• Registration Number: NCT05941403
• Lead Sponsor: Brown University

Brief Summary

The goal of this pilot feasibility implementation trial is to assess preliminary feasibility and acceptability of a set of produce prescription implementation strategies. Produce prescription programs are one approach to addressing food insecurity, or the lack of adequate access to safe and nutritious foods. Produce prescriptions involve healthcare providers identifying patients at risk for food insecurity and writing prescriptions for those patients to receive subsidized vegetables. In this study, the investigators will work with a community advisory board to develop a set of enhanced implementation strategies (e.g., training, technical assistance) to support healthcare providers in delivering produce prescription programs. The investigators will assess the feasibility, acceptability, and appropriateness of these strategies. Pre-post changes in implementation outcomes (i.e., adoption) and effectiveness outcomes (i.e., food security) will be examined.

Detailed Description

Healthcare providers/staff and patients will be recruited from allied Integra health centers. Following enrollment in the already existing produce prescription program ("VeggieRx"), participants will be asked if they would be interested in participating in the research study that entails surveys regarding the program. The investigators expect to recruit participants into the study starting shortly after patients get enrolled in the program. Potential participants will be informed that their decision about whether to participate in the research study will not affect their eligibility or enrollment in the VeggieRx program. They will also be informed that this study seeks to understand strategies to improve the current VeggieRx program. A research assistant will follow-up with interested patients/providers/staff and complete enrollment, consents, and a baseline assessment, either in the waiting room to complete on their own, over the phone or Zoom, OR if they choose to complete it on their own, the study team will send them the link to the consent and survey. It should be noted that participants can either choose to complete the surveys on their own through a survey link (which will be the default) or the surveys can be administered by the study staff. The study team hopes to collect baseline measures before the delivery of their first vegetables which typically begins the second week in July. While providers/staff will not be receiving vegetables, the study team also hopes to collect their baseline data when the program begins (by second week of July). Follow-up data collection for patients will occur after their final delivery (usually end of November) and provider/staff survey will also occur around that time. The study team will communicate with the program to find out when the last deliveries are occurring (not gathering any patient information, just overall timeline).

Baseline and final measures for participating patients are each expected to take approximately 15-20 minutes. In addition, VeggieRx participants will also complete a biweekly measure of engagement which will take approximately 2-minutes each time and will be sent via text message or email depending on participants' preferences throughout the duration of the 6-month VeggieRx delivery period. These questions will ask if they received their vegetable delivery, how much they liked the vegetables, how much they used them and if they fit with their families' eating habits.

As described above, providers and staff will be contacted via email/text/phone by the research assistant asking them to participate. They can complete measures with a research assistant or on their own. Baseline and follow-up surveys for providers/staff are each expected to take 10-20 min. All previously mentioned study procedures can take place in Spanish for patients whose primary language is Spanish by the research assistant research staff that is fluent in Spanish.

Arm && Interventions

Group	Intervention	Description
Enhanced Produce Prescription Implementation	Enhanced Produce Prescription Implementation	The study team will develop an enhanced implementation blueprint to support uptake of the produce prescription (VeggieRx) intervention that is informed by advisory board input and includes multiple implementation strategies to address identified barriers to implementation.

Primary Outcome Measures

Name	Time	Method
Intervention Appropriateness Measure	6 month follow up	Appropriateness of produce prescriptions will be assessed using the 4-item Intervention Appropriateness Measure with scores ranging from 1 (completely disagree) to 5 (completely agree). Higher scores indicate higher appropriateness of the intervention. Scores range from 4-20.
Patient Engagement with the Produce Prescription Program Questionnaire	Week 28	Patient engagement will be measured with a 4-question biweekly questionnaire that includes items rated on a 5-point (1-5) Likert-scale related to whether patients received the produce and whether they used it and liked it. Higher scores indicate higher engagement. Scores range from 4-20.
Acceptability of Intervention Measure	6 month follow up	Acceptability of produce prescriptions will be assessed using the 4-item Acceptability of Intervention measure with scores ranging from 1 (completely disagree) to 5 (completely agree). Higher scores indicate higher acceptability of the intervention. Scores range from 4-20.
Feasibility of Intervention Measure	6 month follow up	Feasibility of produce prescriptions will be assessed using the 4-item Feasibility of Intervention Measure with scores ranging from 1 (completely disagree) to 5 (completely agree). Higher scores indicate higher feasibility of the intervention. Scores range from 4-20.
Evidence-Based Practice Attitudes Scale	6-month follow up	The Evidence-Based Practice Attitudes Scale measures providers' attitudes toward evidence-based practices - specifically produce prescription programs. Scores range from 0 (not at all) to 4 (to a very great extent); higher scores indicate more positive attitudes toward evidence-based practices. Scores are calculated as an average and range from 0-4.
Feasibility of Participant Enrollment	Baseline	Proportion of participants who agree to enroll in the study out of those who are enrolled in the produce prescription program
Implementation Climate Scale	6 month follow up	This measure of implementation climate will assess the innovation-specific organizational climate for implementing produce prescription programs. Responses will be rated on a 4-point scale ranging from 0 (not at all) to 4 (very great extent). Higher responses indicate a stronger implementation climate. Scores are calculated as an average and range from 0-4.
Implementation Readiness: Organizational Readiness for Implementing Change	6-month follow up	This measure will assess organizations' readiness to implement a new intervention. Responses will be rated on a 5 point scale ranging from 1 (disagree) to 5 (agree). Higher scores indicate higher organizational readiness for change. Scores range from 12-60.

Secondary Outcome Measures

Name	Time	Method
Effectiveness: Patient Health Questionnaire-2	6-month follow up	The 2-item Patient Health Questionnaire will be used to screen for depression. Responses range from 0 (not at all) to 3 (nearly every day). Scores greater than 3 suggest that major depressive disorder is likely.
Adoption of Produce Prescriptions	6 month follow up	Number of patients who enroll in the produce prescription program
Effectiveness: Food Security	Baseline	Measured by the 6-item United States Department of Agriculture measure. Total scores range from 0-6, with lower scores indicating more food security.
Effectiveness: Dietary Screener Guide	6-month follow up	Fruit and vegetable intake will be measured by the 10-item Dietary Screener Guide, in which participants will be asked to rate the frequency with which they have eaten a variety of foods. Responses range from "never" to "6 or more times per day." The measure is scored using a scoring algorithm that converts survey responses to estimates of average daily dietary intake for fruits and/or vegetables.
Effectiveness: Nutrition security	6 month follow up	measured by the 4-item Nutrition Security measure. Responses range from "never" (0) to "always" (4). Items are scored by finding a mean of included items. Lower scores indicate more nutrition security.
