Brief Summary

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.

Conditions

Diabetes Mellitus, Type 2

Keywords

Diabetes; Patient Web Portals; Usability; Health Information Technology

Outcome Measures

Primary Outcomes (3)

• Usability

  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.

  one month follow-up (T1)

• User Experience - Quantitative

  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.

  one month follow-up (T1)

• User Experience - Qualitative

  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.
