CHOPR Today

Who We Are

We are leading researchers in the fields of Nursing, Sociology, Public Health, Demography, Medicine, Management, and Economics. We study health system reorganization and policy changes and aim to produce research evidence to improve the quality of health care, the power of policy on hospital organizational traits and context on racial, ethnic, and socioeconomic disparities in health care outcomes.

Our Research Focus

CHOPR investigators explore the nursing workforce; nursing’s contribution to reduce racial, ethnic, and socioeconomic disparities; policies such as scope of practice and nurse-to-patient ratios; nursing inputs such as education, skill mix, and work environment; and how these factors impact patient outcomes.
