Established at the University of Pennsylvania in 1989, the Center for Health Outcomes and Policy Research, also known as CHOPR, operates as a unique community within the School of Nursing.

CHOPR is a research and research-training enterprise focusing on the outcomes of health care and health workforce policy. 

We study health system reorganization and policy changes and aim to produce research evidence to improve the quality of health care.

The Center is the home to foremost researchers in the fields of nursing, sociology, demography, medicine, management, and economics. 

Research, writing, thinking, and conversation at the Center has had a remarkable impact on health care, economics, social science and society.

Investigators explore nursing workforce issues, the supply of nurses, the value of nurse education, and scope of practice and how it impacts patient outcomes.

The CHOPR team studies the power of policy on hospital organizational traits and context on racial, ethnic, and socioeconomic disparities in health care outcomes.

Our policy research agenda is motivated by a commitment to improving health care outcomes by building an evidence base for health service management and providing direction for national policymakers. 

The team examines the effect of changing hospital populations - patients with increasingly complex and chronic conditions - on the organization of nursing care and patient and nurse outcomes.
