A descriptive study of screening and navigation on health-related social needs in a safety-net hospital emergency department

Background: Health-related social needs (HRSN) have been associated with worse clinical outcomes, increased Emergency Department (ED) utilization and higher healthcare costs. The ED is uniquely positioned to bring HRSN screening to the bedside and develop effective interventions. We evaluated whether navigation services for high-risk patients led to the resolution of HRSN. Methods: Navigators screened a convenience sample of patients for HRSN with the Accountable Health Communities Screening Tool from October 2019 to January 2022. Patients with HRSN were considered high-risk if they had at least two ED visits in the previous 12 months. Patients who were high-risk were eligible for navigation including community referrals and one-on-one close follow-up. The HRSN status (resolved, in-progress, unable to resolve) was queried from the Centers for Medicare and Medicaid database. The state hospital association provided data on ED visits and inpatient hospitalizations within 6 months of the screening visit. Results: Of 185,470 ED visits, HRSN screening occurred in 4050 (2%). HRSN were self-reported in 48% (1944) of patient visits, with 71% of these (1379) considered high-risk. 15% of high-risk patients with HRSN opted out of navigation. Food insecurity was the most identified HRSN (35%) followed by housing instability (26%), transportation needs (24%) and utility assistance (15%). Food insecurity was the most resolved HRSN (39%, in-progress 32%) followed by utility assistance (37%, in-progress 26%), transportation needs (35%, in-progress 35%) and housing instability (28%, in-progress 36%). High-risk visits in which the patient or guardian accepted navigation were less likely to be associated with an ED visit within 6 months of the screening visit (51%) compared to high-risk patients in which the patient or guardian opted out of navigation (61%, p < 0.001), but there was no difference in inpatient hospitalizations. (p = 0.427). Conclusions: During the study period, one-third of HRSN were successfully resolved with another one-third in-progress. Navigation in high-risk patients was associated with fewer subsequent ED visits.
