Medicaid Research

Through a partnership the Delaware Division of Medicaid and Medical Assistance (DMMA),  and the College of Health Sciences, CCRS undertakes a number of analyses based on Medicaid data. Medicaid, health insurance coverage for low-income women, men, and children, insures approximately one-fourth of our population in Delaware. Working collaboratively DMMA and other state agencies, CCRS is able to analyze Medicaid paid claims data to identify ways of enhancing the efficiency, effectiveness,  impact, and return on investment of the state and federal Medicaid dollar. 

For more information regarding the Medicaid Research Program, please see the School of Public Policy and Administration Connect Magazine, Vol. #1, Number 1, 2016. Connect article.pdf

CCRS and DMMA are members of AcademyHealth's State-University Partnership Learning Network (SUPLN), an ongoing collaboration that works to facilitate peer-to-peer learning and dialogue among state-university partnerships.

CCRS participates in the Delaware IDeA Network of Biomedical Research Excellence (INBRE) as a member of the DE-INBRE Centralized Share Resources (CSR). 

"Its goal is to expand research activities across basic, translational and clinical areas throughout the First State while also increasing Delawares competitiveness for federal biomedical research funding. In doing so, Delaware INBRE supports impactful, state-of-the-art research that creates jobs, prepares tomorrows workforce and improves the health of Delawareans."

Core Access Award:  Requests for proposals for research based on the Medicaid Claims in the areas of maternal/child health, pediatric populations, and social determinants of health are issued three times a year. Successful projects will be funded in the amount of $8,000 per project to use in support of Medicaid analysis.  For more information, please download the application or contact Mary Joan McDuffie at  mduffie@udel.edu.

The Medicaid claims data files contain claims from FY08 to present.  The database is comprised of five different files:

Medical claims (date of claim, diagnoses, Current Procedure Terminology Codes)

Prescription claims (date of claim, National Drug Codes)

Client demographics (gender, race, birthdate)

Client Supplemental (eligibility, aid category, Primary Care Physician, Family ID, address)

Provider data (address, Provider identification number)

The Medicaid claims database contains a Master Client Index (MCI) variable which allows the files to be linked together.  All individuals in programs within the Delaware Department of Health and Social Services (DHSS) use the same identifier which allows linkage of data across divisions.
