Digital Health Intervention On Awareness Of Vaccination Against Influenza Among Adults With Diabetes

February 17, 2025 updated by: LabStyle Innovations Ltd.
The study leveraged the Dario digital health platform to retrospectively analyze data from 64,904 users with diabetes assigned by the platform into three groups: Group A received previously studied monthly flu nudge messages; Group B received an adapted intervention with 2-3 monthly messages; Group C served as the control with no intervention. Surveys were conducted at baseline, three months, and six months to assess vaccination status, awareness of influenza risks, and recollection of educational content. Statistical analyses, including logistic regression, Chi-square tests, and t-tests, were used to evaluate differences between groups.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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.

Detailed Description

The goal of this study was to retrospectively evaluate the effectiveness of an adapted digital nudge intervention that was designed previously in an RCT setting to increase influenza vaccination rates for PWD in real world setting. The primary objective was to examine the difference in self-reported influenza vaccination rates in three groups: PWD who received the intervention using a previously published approach (group A), PWD who received an adapted digital intervention (group B) and PWD who received no intervention (group C or control). A secondary aim was to investigate whether the intervention led to differences in awareness and knowledge across study groups and examined the relationship between awareness of influenza risks and vaccination rates.

The data was collected between September 2022 and March 2023 to evaluate the effectiveness of an adapted digital nudge intervention designed to increase influenza vaccination rates among people with diabetes (PWD) in a real-world setting. The intervention builds on a previously conducted randomized controlled trial (RCT). Users were automatically assigned to three groups via the customer engagement platform using a randomization algorithm to assign each selected user to one of the test variations. This ensured that each user had an equal chance of being placed in any of the groups.

The three groups are defined as follows: group A received flu nudge messages as described previously in a randomized clinical trial with one message given each month for six months; Group B received similar messages that were adapted in frequency with 2-3 messages per month for six months and matched the Dario platform's user experience; group C received no flu nudges (Control). No compensation was offered. The intervention messages included education and recommendations related to the importance of getting flu vaccination in the diabetes population.

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.

Description

Inclusion Criteria: subjects from the United States utilizing a Dario application who reported in the app during registration that they had a diagnosis of type 1 or 2 diabetes and who were active on the platform (logged into the app) during the 12-month period up to Sep 2022.

Exclusion Criteria: subjects that are not using Dario platform

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
Differences in vaccination rates between the study groups
Time Frame: 6 months
differences between the groups in users with diabetes self-reported influenza vaccination status
6 months

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
Content related differences between the groups
Time Frame: 6 months
Differences in awareness and knowledge retention levels between the groups measured by response to the question: "Do you know the risks getting the flu has for someone with diabetes" and differences in recollection of educational content between the groups, measured by a self-reported question: "Do you remember seeing any of these messages?"
6 months
