Analysis of the food insecurity screening and referral program at three sites of the University of California San Diego (UCSD) Student-run Free Clinic Project (SRFCP) from January–July 2015 using the RE-AIM framework (Reach, Effectiveness, Aim, Implementation, and Maintenance).

RE-AIM element	Outcome
Reach
Exclusion criteria	None
Percent individuals who participated	92.5% (430/463 patients screened)
Effectiveness
Measure of primary outcome: Food insecurity	74.0% (318/430 of patients screened) were food insecure, including 30.7% (132/430) with very low food security
Measure of broader outcomes: Utilization of referral to food resources	201 received boxes of nutritious food onsite 66 used an off-site food pantry, 64 enrolled in the Supplemental Nutrition Assistance Program (SNAP)
Adoption
Setting Exclusions	None
Percent of settings approached that participated	100% (3/3)
Characteristics of settings participating	Three Student-run Free Clinics in San Diego, California serving a low-income, uninsured, largely Latino patient population
Utilization of food insecurity registry	92.5% (430/463) of patients seen had food insecurity screening results entered into the registry
Implementation
Percent of perfect delivery, adaptations made to intervention	The intervention was delivered as intended, no known adaptations were made.
Cost of intervention	There were no costs to screening and making referrals as volunteer staff performed screening, referrals, tracking, and follow-up.
Consistency of implementation across staff, settings, subgroups	No known inconsistencies.
Maintenance
Long term attrition	Volunteers are conducting follow-up screening for food insecurity at all three sites and patients have not refused to fill out follow-up surveys.
If program is still ongoing at least 6 months post study	Follow-up food insecurity screening and referrals, including on-site food distributions, are being provided over one year after initial study completion.
If and how program was adapted long term	This program has grown to routine food insecurity screening every 6 months. Partnership with a local food bank, Feeding San Diego, was developed to allow distribution of healthy food on-site to all patients.
Alignment of organization mission or sustainability	Pre-existing mission statements of UCSD Student-run Free Clinic Project and Feeding San Diego are well-aligned with addressing food insecurity in health care. Both organizations are committed to sustainability of this project.
