Voice-activated and Touchscreen-controlled Smart Speaker Intervention for Older Adults With Poorly Controlled Type 2 Diabetes (VATC-SS)

July 24, 2026 updated by: Aprill Z. Dawson, PhD, MPH, Medical College of Wisconsin
This is a pre-post pilot study that will test the feasibility and acceptability of a health educator delivered diabetes education and skills training intervention using a voice-activated, touch screen controlled, smart speaker. We will enroll 30 adults aged 50 and older with poorly controlled type 2 diabetes as defined by a hemoglobin A1C of 8% in the study.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
HemoglobinA1C
Time Frame: Baseline and 3-months post enrollment
About 10cc of blood will be drawn by phlebotomist and sent to the lab for testing
Baseline and 3-months post enrollment
Blood Pressure
Time Frame: Baseline and 3-months post-enrollment
Blood pressure readings will be obtained using automated blood pressure monitors (OMRON IntelliSenseTM HEM-907 XL). The device will be programmed to take 3 readings at 2-minute intervals and give an average of the 3 blood pressure readings.
Baseline and 3-months post-enrollment
Low-Density Lipoprotein Cholesterol
