P-2058. Healthcare Utilization Before and After Enrollment in the New York City Health + Hospitals/Bellevue Health Equity Action Team, 2022-2024

Abstract Background Patients hospitalized with HIV-related complications and substance use-related infections (e.g., endocarditis) often face sociostructural inequities that lead to poor health outcomes. Hospitalization is a key opportunity to address health-related social needs (HRSN) and reduce avoidable emergency department (ED) visits and readmissions. The Health Equity Action Team (HEAT), launched in July 2023 at NYC Health + Hospitals/Bellevue, provides inpatient consult and post-discharge navigation for patients with complex HRSN. HEAT leverages HRSN screening, trauma-informed care, peer support, and community partnerships to promote primary care utilization over ED or hospital-based care. We explored HEAT’s preliminary healthcare utilization outcomes before and after HEAT intervention. Methods We conducted a retrospective pre-post analysis of 35 patients who received the HEAT intervention (Figure 1) between January 1, 2022 and December 31, 2024. Manual chart review captured patient demographics, co-morbidities, and healthcare utilization six months pre- and post-HEAT consult. Outcomes included outpatient visits, ED visits, hospital admissions, and readmissions. We calculated means, standard deviations (SDs), and compared pre- and post-HEAT outcomes using paired t-tests at p 0.05 as significant. Results Participants were majority male (74%), Black (40%) or Latinx (49%), on Medicaid (83%), and experiencing homelessness (77%) (Table 1). Most (80%) had substance use disorder (SUD), 54% had HIV, 34% had both SUD and HIV, and 49% had hepatitis C. Substance use included primarily cocaine and opioids (Table 2). Mean outpatient visits from pre- to post-HEAT increased significantly (0.4 SD 0.9 to 3.1 SD 4.5, p 0.01). ED visits remained stable (3.7 SD 5.0 vs. 3.2 SD 3.7, p = 0.61), as did hospital admissions (1.1 SD 1.8 vs. 1.7 SD 2.3, p = 0.20) and readmissions (1.0 SD 1.8 vs. 1.1 SD 2.1, p = 0.84). Conclusion HEAT intervention was associated with increased outpatient follow-up among patients with HIV and SUD with historically low engagement in post-discharge primary care. Hospital and ED use remained stable. Future studies will assess HEAT’s long-term impact on healthcare utilization, quality, and safety.
