Overview
Brief Summary
The purpose of this study is to evaluate the usability of a novel patient portal intervention designed to: (a) notify patients when selected, clinically meaningful, evidence-based diabetes monitoring & preventative care (e.g., annual diabetes eye exam) become due and (b) allow patients to initiate orders for the care. In addition, the investigators will assess pre-post change on secondary psychosocial outcomes (e.g., self-efficacy).
Detailed Description
Up to 60 adult patients with type 1 or 2 diabetes mellitus will be enrolled and given access to a new feature within the patient portal at Vanderbilt University Medical Center. The new feature will be available via the patient portal native app (i.e., My Health at Vanderbilt (MHAV) app) for mobile devices (smartphone or tablet). The new feature will allow patients to: (1) receive notifications when the patient is due for certain types of diabetes monitoring and preventative care and (2) initiate an order for the care. Study participants will complete questionnaires electronically via email at three time points: baseline (T0), immediately after first use of the intervention (T1), and three-month follow-up (T2) to as assess study outcomes including usability and pre-post change in secondary psychosocial outcomes.

Outcomes
Primary Outcomes
Usability
Time Frame: Immediately after first use T(1), at approximately 1 month
The System Usability Scale (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.
User Experience
Time Frame: 3-month follow up (T2)
User experience will be assessed by study-specific survey items administered to all participants at the end of the study period (T2). The survey items will inquire about participants' perspectives on the acceptability of the intervention and on particular components of the intervention such as notifications.
Secondary Outcomes
- Change in Understanding of Diabetes Monitoring and Preventative Care(Enrollment (T0) and 3-month follow up (T2))
- Order Completion(3-month follow up (T2))
- Change in Attitudes Toward Managing Diabetes in General(Enrollment (T0) and 3-month follow up (T2))
- Patient Initiated Orders(3-month follow up (T2))
- Change in Diabetes Distress(Enrollment (T0) and 3-month follow up (T2))
