Evaluation of the use of digital fundus camera for diabetic retinopathy screening
Drs. Bell, Baker and Valentino designed a study of the sensitivity and specificity of digital fundus photography in screening for diabetic retinopathy. If effective, this technology would enhance access to screening that could prevent blindness for a large group of urban minority patients with diabetes. Dr. Valentino and Mr. Wei designed and implemented software to perform the study. The software includes functionality to collect and store the retinal images acquired using the digital fundus camera, and to distribute the study data to the participating physicians. All of the software was written in Java, validated to run on several platforms, and available to our collaborators via an Open Source license. Drs. Bell and Baker resolved several clinically-related issues that delayed the study's launch, including difficulties with Spanish translations of the consent documents, and logistical obstacles at the Hubert Humphrey Comprehensive Health Center. We are currently beginning recruitment for the study, and anticipate collecting the data before the end of this calendar year.
Health Disparities Research Consortium
We have initiated a collaboration with the Informatics investigators at RCMI programs at the University of Puerto Rico and at the University of Hawaii to create a formal collaborative network to conduct studies aimed at reducing or eliminating health disparities in diabetes mellitus, a chronic disease with multiple serious complications which disproportionately affect African American, Hispanic, Asian, and Pacific Islander populations, groups which are served by the three institutions. The CDU RCMI Informatics Core is providing the tele-research and software expertise as well as the software foundation for this project. The Internet 2 infrastructure, required for this endeavor, is expected to be operational by the end of July 2003. The telemedicine investigators at CDU will form the "informatics hub" for this project, lending their considerable expertise and skill to the design, implementation, and management of this project.
