UCSF Health - Office of Population Health

The Office of Population Health (OPH) was created in 2015 to lead UCSF Health’s efforts to improve the health of our patients, improve the experience for our patients, and lower the costs of care delivered. We work closely with leadership across UCSF to execute a system-wide strategy of delivering innovative models of value-based care. 

We lead UCSF’s participation in 1) state pay-for-performance programs, 2) alternative payment models such as Accountable Care Organizations (ACOs) and bundled payments, and 3) population health quality for UCSF and our partners.

We are comprised of three primary components:

  • Innovative clinical programs focused on improving the health of patients throughout the care continuum
  • Data and analytics aimed at analyzing and disseminating clinical and cost data
  • Project management team focused on population health value-based care quality and pay-for-performance programs

The Office of Population Health (OPH) is committed to the systemic study and evaluation of UCSF Health patient populations and population health management interventions using a learning health system (LHS) approach. The National Academy of Medicine defines a LHS as “one in which knowledge generation is so embedded into the core of the practice of medicine that it is a natural outgrowth and product of the healthcare delivery process and leads to continual improvement in care.” OPH collaborates with faculty, staff and trainees at UCSF who share a commitment to a LHS approach.  The OPH LHS team 1) systematically designs and evaluates OPH interventions, 2) produces generalizable knowledgeable that may be disseminated in scholarly products, and 3) balances pragmatism, feasibility, and scientific rigor in OPH’s work and goals.
