CHPR provides a nexus for investigators from a broad range of disciplines to collaborate on impactful research that informs healthcare delivery, quality, outcomes and costs. The Center plays a unique role at UC Davis in supporting and fostering interdisciplinary research collaborations on these important health services research topics.

Currently, the majority of CHPR research projects fall into the following four research program themes:

In each of these program areas, CHPR investigators and staff conduct high-impact work, much of which has informed clinical guidelines and health policy over the Center’s 25-year history.

Research Services

CHPR faculty and staff support health services research collaborations by contributing their subject matter expertise in the following areas:

  • Study design options
