The Keck-Schaeffer Initiative for Population Health Policy (KSI) is a collaboration between the Keck School of Medicine of USC and the USC Schaeffer Center for Health Policy & Economics. Housed in the USC Roski Eye Institute and created with support from the USC Department of Emergency Medicine and the Schaeffer Center, the KSI will foster multidisciplinary collaborations to generate new research and educational opportunities to study population health policy at the Keck School of Medicine.
The KSI is conducting cutting edge research designed to improve population health across several key areas. Currently, our ongoing work addresses the following topics:
- Expanding access to high quality vision care
- Improving behavioral health care in the US
- Reducing the burden of disability due to injury or chronic illness
- Fighting America’s opioid epidemic
