Selected Research

Development and Performance of Medicaid ACOs

Dr. DeLia is principal investigator of this project funded by the Agency for Healthcare Research and Quality. This project will measure the impact of Medicaid ACOs in NJ on healthcare spending and quality, assess the accuracy and statistical reliability of alternative methods used to establish savings associated with Medicaid ACO activities, describe how NJ ACOs respond to key organizational challenges, and inform decision making about accountable care policy and practice in NJ and nationally. The project receives additional support from The Nicholson Foundation for enhanced qualitative analysis of ACO operations and care management strategies.

Evaluation Design and Implementation for the Transforming Complex Care (TCC) Initiative

Dr. DeLia is the principal investigator of this project funded by the Center for Health Care Strategies through the Robert Wood Johnson Foundation, which provides technical assistance to help six sites across the nation track performance in their complex care initiatives. The project also supports in-depth rigorous evaluations for a subset of the sites.

Medicaid Policy and the Supply of Primary Care

Dr. DeLia is the principal investigator for this project funded by the Robert Wood Johnson Foundation. This project will analyze how negotiated prices and other factors affect the supply of primary care delivered to Medicaid patients, especially those who are homeless or have severe mental illness.

Understanding Which Injured Older Adults Benefit from Triage to a Trauma Center

Dr. DeLia is dual-principal investigator (with Kit Delgado from University of Pennsylvania) for this project, which is funded by the National Institute on Aging.  The project will determine which clinical subgroups of injured older adults benefit most from triage to a trauma center vs. a non-trauma center and determine whether rates of complications and death after the development of complications for older adults differ by trauma center status and injury severity.
