Feasibility of an Emergency Department-based Food Insecurity Screening and Referral Program.

Introduction: Food insecurity (FI) remains a pervasive issue in the United States, affecting over 12.8% of households. Marginalized populations, particularly those in urban areas, are disproportionately impacted. The emergency department (ED) holds potential as a vital outreach hub, given its diverse patient population and extensive service coverage. In this study we explore the feasibility of implementing an ED-based FI screening and referral program at an urban, academic teaching hospital. We aimed to assess the prevalence of FI among ED patients and evaluate the feasibility of a three- and six-week follow-up to assess patients' FI and related barriers to resource referral utilization.

Methods: This single-center, observational study was conducted at an urban, academic ED from 2018-2024. Initial FI screening was performed using a validated two-question survey adapted from the Hunger Vital Sign screening tool. Participants who screened positive were enrolled and completed the 10-item US Department of Agriculture Adult Food Security survey, received a food assistance guide, and were followed up at three- and six-week intervals to assess changes in FI status.

Results: Among 6,339 participants, 1,069 (16.9%) experienced FI, with the highest rates among Black non-Hispanic (24.7%) and Spanish-speaking participants (28.7%). Of the 1,069 participants who screened positive for FI, 630 (59.0%) were enrolled in the study. Of the enrolled participants, 161 (25.6%) completed the three-week follow-up phone calls, and 48 (7.6%) completed the six-week follow-up. The mean FI score for these 48 participants decreased from 6.67 (SD 2.68) at enrollment to 4.75 (SD 2.85) at the three-week follow-up (P < 0.001), and to 4.25 (SD 3.48) by the six-week follow-up (P < 0.001). Barriers to using the food resource guide, such as time constraints, transportation, and misplacement of resources, limited many participants' engagement.

Conclusion: This study demonstrated the feasibility and effectiveness of an ED-based food insecurity screening and resource referral program, associated with a significant reduction in food insecurity scores among participants. However, barriers such as time constraints, transportation issues, and misplacement of referral materials limited engagement. Addressing these barriers through tailored follow-up and systematic support systems, including universal screening during ED intake and personalized assistance, can enhance the program's accessibility and impact.
