Diabetes data management programs upload glucose meter results to computers to provide information to lay persons and their health care professionals. With this data management system glucose results from the DIDGET TM meter can be uploaded to a secure website and used by adults with diabetes, by parents and guardians of children with diabetes, and by health care professionals to monitor diabetes by recognizing trends and patterns in blood sugar levels. During the study subjects performed specific tasks, such as uploading meter results and displaying reports. The study evaluates the subjects' success in using the software program, the program's ease of use, clarity and usefulness of user instructions, and user satisfaction with the diabetes data management program.
