Brief Summary

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.

Conditions

Diabetes; Diabetes (DM); Type 2 Diabetes

Outcome Measures

Primary Outcomes (3)

• HemoglobinA1C

  About 10cc of blood will be drawn by phlebotomist and sent to the lab for testing

  Baseline and 3-months post enrollment

• Blood Pressure

  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

  About 10cc of blood will be drawn by phlebotomist and sent to the lab for testing

  Baseline and 3-months post-enrollment

Secondary Outcomes (3)

• Depression

  Baseline and 3-months post-enrollment

• Social Isolation

  Baseline and 3-months post-enrollment

• Loneliness

  Baseline and 3-months post-enrollment
