Social drivers of health (SDOH)—the conditions in which people are born, grow, live, work, and age—powerfully shape both health outcomes and healthcare utilization. Socioeconomic factors alone are estimated to account for 47% of all health outcomes, outweighing the influence of individual health behaviors (34%), clinical care (16%), and the physical environment (3%). Housing instability and food insecurity are also independently associated with increased emergency department (ED) use and hospitalizations—highlighting how unmet social needs and structural inequities directly surface in acute care settings.
At the same time, opioid use disorder (OUD) remains common and profoundly undertreated. In 2022, an estimated 2.7 million people in the United States were living with OUD, and overdose remains a leading injury-related cause of death, with over 106,000 overdose deaths in 2021, including 80,411 involving opioids. Although medications for OUD (MOUD) such as buprenorphine are highly effective, an estimated ~90% of people with OUD do not receive MOUD, reflecting persistent barriers to evidence-based addiction treatment.
The ED represents a critical—and often singular—opportunity to reach patients facing the greatest social and medical vulnerability, initiate life-saving interventions, and connect them to longitudinal care they might otherwise never access.
Yet this safety-net role increasingly collides with the reality of an already overburdened emergency clinician workforce and the cognitive overload of time-pressured decision-making.
The Molina Lab sits at the intersection of clinical informatics, social emergency medicine, health equity, and addiction medicine. Our mission is to leverage innovative electronic health record-based technologies and clinical decision support to enable whole-person care—improving outcomes for patients while reducing cognitive burden and workflow friction for emergency physicians.
