简要总结
The purpose of this study is to conduct a prospective, longitudinal study to evaluate the usability of a patient-facing diabetes dashboard delivered via an established patient web portal.
详细描述
Up to 70 adult patients with type 2 diabetes mellitus will be enrolled and given access to a diabetes dashboard within an existing patient web portal. Patients will be invited by mail (or email) to be screened for enrollment in the study. Patients may also respond at a study flyer and contact the study team to be screened for enrollment. Eligible and interested patients will be emailed a link to a secure study website where they will complete a web consent form. After enrollment, participants will complete a baseline web-based questionnaire. After completing the enrollment questionnaire, they will be provided access to the diabetes dashboard within the patient web portal for one month. After one month, participants will receive an additional follow-up (final) questionnaire to assess outcomes.

结局指标
主要结局
User Experience - Quantitative
时间窗: one month follow-up (T1)
User experience will be assessed by study-specific survey items administered to all study participants at the end of the study period (T1). The survey items will inquire about participants' perspectives on particular features of the Patient-facing Diabetes Dashboard. Participants were asked to indicate which features, if any: (1) they found useful for managing their diabetes and which features, (2) improved their understanding of their diabetes health data, and (3) should be removed. In addition, participants indicated whether they intended to use the dashboard going forward if it remained available.
User Experience - Qualitative
时间窗: one month follow-up (T1)
At the end of the study period (T1), a subset of study participants will be invited to complete a semi-structured interview to provide a deeper understanding of their experience using the dashboard.
Usability
时间窗: one month follow-up (T1)
The System Usability Scale (SUS) will be administered to all study participants at one month follow-up (T1). The SUS is a validated measure of usability. The ten items are scored on a five-point Likert scale. The item scores are summed and then converted to a score ranging from 0 (worst) to 100 (best). A score of above 68 indicative of "above average" usability.
