The Intelligent Diabetes TelemonitoRing Using Decision Support to Treat Patients on Insulin Therapy (DiaTRUST)
February 19, 2024 updated by: Peter Vestergaard, Aalborg University Hospital
The Intelligent Diabetes TelemonitoRing Using Decision Support to Treat Patients on Insulin Trial: Study Protocol for a Randomized Controlled Trial
The trial is an open-label, randomized controlled trial.
Patients with T2D on insulin therapy will be randomized to an intelligent telemonitoring group (intervention), a telemonitoring group (control), and a usual care group (control).
Both the intelligent telemonitoring group and the telemonitoring group will use various devices at home.
Hospital staff will monitor their data for six months.
In the intelligent telemonitoring group, hospital staff and participants will be supported by decision-support algorithms in the management of insulin treatment.

Detailed Description
The DiaTRUST trial is an open-label randomized controlled trial with a six-month trial period.
The trial will be conducted at Steno Diabetes Center North Jutland.
Patients with T2D on insulin therapy will be randomized (3:1:1) to an intelligent telemonitoring group (intervention), telemonitoring alone (control), or a usual care group (control).
Both telemonitoring groups will use an insulin pen, an activity tracker, a CGM, and a smartphone application throughout the trial period.
Hospital staff (lab technicians and nurses) will monitor the telemonitoring groups' data and contact the subjects by telephone repeatedly throughout the trial period.
For patients assigned to the intelligent telemonitoring group, decision support algorithms will provide hospital staff with insight and data overviews to support treatment evaluation and adjustment throughout the trial.
Furthermore, patients in the intelligent telemonitoring group will have access to algorithms through a smartphone application that can provide a risk assessment before bed of nocturnal hypoglycemia.
The usual care group will use a blinded CGM for the first 20 days after inclusion, 20 days before the second visit to the trial site, and 20 days before the end of trial and will use a blinded insulin pen for the entire period.
The usual care groups' data will not be monitored during the trial.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Intelligent telemonitoring
The subjects will be telemonitored using the intelligent telemonitoring system.
All subjects will use a CGM, a Fitbit, and a smart pen during the trial period.
Staff at the endocrinology clinic will monitor the data and contact the subjects continuously throughout the trial (depending on the individual needs of each subject) using the intelligent telemonitoring system with embedded decision support to facilitate treatment evaluation and adjustments.
The subjects will have access to a smartphone app that is able to provide a risk for nocturnal hypoglycemia before bed.

Active Comparator: Telemonitoring
The subjects will be telemonitored.
All subjects will use a CGM, a Fitbit, and a smart pen during the entire trial period.
Staff at the endocrinology clinic will monitor the data and contact the subjects continuously throughout the trial (depending on the individual needs of each subject)
|
Telemonitoring using CGM, insulin pen data, and Fitbit data
|
No Intervention: Usual care
The subjects will wear a blinded CGM the first 20 days after inclusion, 20 days before the second visit to the trial site, and the final 20 days of the trial.
The subjects will use a blinded smart pen throughout the trial period.
Hence, the subjects cannot see their measured data during the trial and will not be monitored.
