mHealth Insulin Titration and Management (iSage)

August 4, 2023 updated by: University of Kansas Medical Center
The purpose of this study is to determine the benefits of using the iSage app for basal insulin titration and support. By doing this study the investigators hope to learn whether the app improves the participant's ability to follow his/her healthcare provider's instructions to adjust his/her insulin doses.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: iSage for adjustment of insulin
The provider will prescribe the iSage app to the subject and choose a treatment algorithm within the app to make insulin dose adjustments.
Other: iSage
The provider will choose a treatment algorithm within the iSage app and set the parameters to make insulin dose adjustments no less frequently than every 7 days. The patient is instructed to perform daily fasting glucose measurements and follow the app's recommendations for insulin adjustment.
No Intervention: Conventional management
Our clinic uses a modified treat-to-target algorithm which is summarized on a 3 x 5 refrigerator magnet.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Concentration of HgbA1c
Time Frame: 90 days
The investigators will compare changes in HgbA1c from baseline to day 90.
90 days
Number of participants meeting HgbA1c <7%
Time Frame: 90 days
The investigators will calculate the percent of patients achieving HgbA1c <7% at day 90.
90 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sustained use of the iSage app (iSage group only)
Time Frame: 90 days
The investigators will compare the percentage of subjects using the app as prescribed versus "dropouts".
90 days
Hypoglycemia
Time Frame: 90 days
The investigators will record the number of episodes of hypoglycemia, to include severity of event, related symptoms, and time of day.
90 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Healthcare resource utilization
Time Frame: 90 days
Number of contacts with healthcare resources (including telephone calls), ER visits, clinic visits, hospitalizations
90 days
Diabetes Quality of Life Survey (DQOL)
Time Frame: 90 days
The investigators will compare DQOL scores from baseline to day 90. The 15-item DQOL Brief Clinical Inventory provides a total health-related quality of life score that predicts self-reported diabetes care behaviors and satisfaction with diabetes control as effectively as the full version of the instrument. Items are scored on a 5-point Likert scale and are of two general formats. One format asks about the frequency of negative impact of diabetes itself or of the diabetes treatment (i.e., "How often do you worry about whether you will pass out?") and provides response options from 1 (never) to 5 (all the time). The second format asks about satisfaction with treatment and quality of life (i.e., "How satisfied are you with the time you spend exercising?") and is scored from 1 (very satisfied) to 5 (very dissatisfied). Higher scores are negatively valanced, indicating problem frequency or dissatisfaction.
90 days
Insulin Treatment Satisfaction Questionnaire (ITSQ)
Time Frame: 90 days
The investigators will compare ITSQ scores from baseline to day 90. The 22-item ITSQ is applicable to a wide variety of insulin therapies, and measures insulin treatment satisfaction assessing regimen inconvenience, lifestyle flexibility, glycemic control, hypoglycemic control, and satisfaction with the insulin delivery device. The response scale is ordinal, ranging from 1 (extremely satisfied) to 6 (extremely dissatisfied). The ITSQ is scored among 5 content clusters, forming a total ITSQ score between 0% to 100%, where 100% indicates complete satisfaction with insulin treatment.
90 days
iSage Product Satisfaction Survey (iSage group only)
Time Frame: 90 days
The investigators will assess iSage app ease of use and satisfaction. Survey consists of 3 items. Answer choices range from 1 (strongly disagree) to 5 (strongly agree).
90 days
