Research Studies

The Center for Healthcare Delivery Research and Innovations (HDRI) produces impactful evidence to strengthen health care delivery in the United States and internationally. The interdisciplinary scientists at HDRI have expertise in studying health care policy, organizations, workforce, and quality of care and patient outcomes. One of the main focuses of HDRI is how to optimally utilize health care professionals, particularly the growing nurse practitioner (NP) workforce, and build health care teams to ensure that patients, particularly racial and ethnic minorities, persons living with dementia, and those in underserved areas, have access to timely, high quality, safe health care services.
