SIMINERIO, CHIN-FUN CHU, DEIDRA COLEMAN, Hous- ton, TX, Pittsburgh, PA Chronicle Diabetes is a web-based system for ADA recognized educa- tion programs on diabetes education documentation. However, follow-up on patient behavioral goals has proven to be challenging for both patients and diabetes educators despite the availability of this tool. After rounds of inter- views seeking educators’ insights on their needs, we developed an interface in the Chronicle Diabetes system that enables educators to view patients’ self-monitoring data, captured via a fi tness tracker and its companion smart- phone application. This self-monitoring data was presented in Chronicle Dia- betes in a monthly calendar view, and included weekly totals and averages calories consumed and burned, steps, and macro-nutrient content. The aim of this study was to describe the patient and educator engagement during 2230-PUB the development and usability evaluation processes of this connected system. A think-aloud protocol was developed for user testing with 7 educa- WITHDRAWN tors to identify their concerns with the use of the connected system in their work setting and for follow-up on behavioral goals related to diet and physi- cal activity. After further refi nement on the system based on the think-aloud testing with the educators, a 2-week pilot study was conducted to test the connected interface with 8 patient-educator dyads. Patients and educators rated highly on perceived usefulness and acceptability of the system. Quali- tative interviews further showed the system in facilitating patients setting realistic goals, receiving more personalized care, and improving communica- tion with educators. Patient and educator experiences, issues, and sugges- tions in using the connected system were summarized. Engaging patients and educators in the development and testing of the connected system improved system usability, lending promise for easy adoption and dissemi- nation of the system in a larger scale. 2231-PUB Supported By: Robert Wood Johnson Foundation Blood Glucose Profi le in Chinese with Diabetes in Real World JIANZHONG XIAO, LING-WANG AN, Beijing, China Background: Self-blood glucose monitoring (SBGM) is important for diabe- tes care.
