Natural Experiments for Translation in Diabetes (NEXT-D): Effectiveness of a National Health Care Community Partnership to Prevent Diabetes
About this Project
The Natural Experiments for Translation in Diabetes (NEXT-D) Study is a network of academic, community, industry, and policy partners, collaborating to advance the methods and practice of natural experimental research, with a shared aim of identifying and prioritizing the best policies to prevent and control diabetes. Funded by CDC and NIDDK (U58 DP002718), our team at NU is collaborating with UnitedHealth Group’s Center for Healthcare Reform and Modernization and Y-USA to study the national rollout of UHG’s policy to pay for community-based diabetes prevention services that target several million eligible adults with pre-diabetes in almost 50 large geographic markets throughout the U.S. This initiative combines actions at the purchaser, community resource, and public policy levels and leverages efforts by CDC and Y-USA to build the capacity of community organizations nationwide to deliver a standardized lifestyle intervention program derived from the DPP. The study will use an interrupted time series with propensity-matched comparison series design to assess effects by UHG, YUSA, and local YMCA to target, identify, engage, and enroll participants across different demographic subgroups (e.g. men/women; age categories; socioeconomic position). By integrating additional data from YUSA, NEXT-D will also examine how implementation varies across regions. Outcomes include changes in prescription costs, obesity-related risk factors such as total cholesterol and hemoglobin A1c’s; healthcare utilization (e.g. ambulatory care, ED, and hospital encounters); and total healthcare expenditures. NEXT-D is led by Dr. Ackermann, Dr. Tang, Dr. Liss, Dr. French, Ms. Moran, Mr. Cooper, Mr. Kang, and colleagues at IU School of Medicine in Indianapolis, IN.
