PROJECT SUMMARY/ABSTRACT – Health Informatics in Diabetes Research Regional Resource Core The primary goal of the Health Informatics in Diabetes Research Regional Resource Core (HIDR) is to advance the development and application of health informatics focused on translating interventions to reach populations at risk for diabetes disparities. HIDR has provided health informatics support for a wider scientific community of Washington University Center for Diabetes Translation Research (WU-CDTR) investigators focused on improving diabetes translation research through the technology and information environment. Poor access to care, particularly for rural populations, is a barrier to improving diabetes outcomes; informatics strategies (e.g., telehealth) can help overcome these barriers. The HIDR Core capitalizes on collaborations with the University of Missouri’s statewide network of health care sites and extension centers, as well as the Missouri Telehealth Network, an innovative program that reaches socioeconomically disadvantaged rural communities across the state in partnership with health care organizations and key stakeholders. HIDR services have expanded in response to the use of health information technologies (e.g., eHealth, mHealth, and telehealth) and the requests for services addressing the root causes of diabetes inequities. HIDR is valued for its expertise in responding to rapid changes in healthcare arising from increased use of health information technology, telehealth, and complex big data sets. The specific aims of the HIDR services for WU-CDTR investigators are to: (1) expand the application of evidence-based health information technologies in diabetes translation research; (2) increase the capacity for the use of telehealth in diabetes research among WU-CDTR investigators; and (3) advance means of managing, scaling, and analyzing information from large, heterogeneous data sets to accelerate the progress of diabetes translation research. HIDR provides Center investigators the expertise and resources needed to ensure excellence in the conduct of health informatics diabetes translation research, and the opportunity to achieve diabetes health equity in rural and disadvantaged populations. HIDR support of diabetes translation research is needed to accelerate new and evolving methodologies and approaches to care that improve health outcomes.
