Trial Outcomes & Findings for Evaluation of a Patient Portal Intervention to Address Diabetes Care Gaps (NCT NCT04728620)

NCT ID: NCT04728620

Last Updated: 2023-08-01

Results Overview

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.

Participant Flow

Of the 60 enrolled participants, 50 completed the baseline questionnaire and still had at least one diabetes care gap (due for any of the following: hemoglobin A1C, urine microalbumin, diabetes eye exam, and/or pneumococcal vaccination) and were then assigned to the intervention.

Intervention
Participants will have access to a new feature within an established patient portal native app on mobile devices. The new feature aims to address diabetes care gaps. Diabetes Care Gaps Patient Portal Intervention: The Diabetes Care Gaps Patient Portal Intervention involves a new feature embedded with the My Health At Vanderbilt (MHAV) native app (on Epic's MyChart platform) for mobile devices that allows patients to: (a) receive notifications when the patient is due for certain types of diabetes monitoring and preventative care and (b) initiate an order for the care. Automated notifications will be sent to patients if, according to the evidence-based guidelines, the patients are due for a hemoglobin A1C blood test, microalbumin urine test, diabetes eye exam, or pneumonia vaccination. Once notified patients can initiate orders for the care within the MHAV app. The patient will receive confirmation when the order has been processed and will be provided instructions to receive the relevant care.

PRIMARY outcome

Timeframe: Immediately after first use T(1), at approximately 1 month

Population: 36 participants used to the study intervention during the study period and completed the SUS scale after first use.

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.

PRIMARY outcome

Timeframe: 3-month follow up (T2)

Population: Not all patients completed this item on the final questionnaire (T2), results limited to the 47 who responded to the items.

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 outcome

Timeframe: Enrollment (T0) and 3-month follow up (T2)

Population: 4 participants did not complete the Manage Disease in General Scale on the three-month follow-up post-questionnaire and were excluded from this analysis.

The 5-item Manage Disease in General Scale of the Chronic Disease Self-Efficacy Scales is a validated measure of self-efficacy (i.e., the confidence a person has in managing their own health and health care) and is closely related to patient activation. The items were adapted to be specific to diabetes rather than a generic condition or illness. Each item uses a 10-point Likert-type scale of response options ranging from 1 (not at all confident) to 10 (totally confident). The score for the scale is the mean of the items. Higher scores indicate greater self-efficacy.

Population: 4 participants did not complete the Problem Areas in Diabetes Scale (PAID-5) on the three-month follow-up post-questionnaire and were excluded from this analysis.

The Problem Areas in Diabetes Scale (PAID-5) is a valid measure of diabetes distress. Total scores on the PAID-5 can range from 0 to 20, with higher scores suggesting greater diabetes-related emotional distress.

Population: Not all patients answers all Understanding of Diabetes Monitoring and Preventative Care items on both the baseline (T0) and three-months (T2). Participants with missing this data at either time point were excluded from the analysis with up to 5 participants missing data for one of items.

Unique study specific items to assess participants' understanding of measures of diabetes monitoring and preventative care (e.g., Diabetes Eye Exams) will be administered to all study participants.

The investigators will collect data on the number of patient-initiated orders for evidence-based diabetes monitoring and preventative services (e.g., hemoglobin A1c). Participants with more than one diabetes care gap can initiated an order for more than one evidence-based diabetes monitoring and preventative service (e.g. hemoglobin A1c and diabetes eye exam).
