The Smartphone and Wearable Detected Atrial Arrhythmia in Older Adults Case Finding Study (Smart in OAC - AFNET 9) (Smart in OAC)

July 4, 2022 updated by: Atrial Fibrillation Network

Multicentre, Intern., Inv.-Initiated, Single-arm Case-finding Study of a Cloud Based Analytic Service as Screening Tool to Detect and Quantify Episodes of Absolute Arrhythmia Using an Automated, Wearable PPG-based Monitoring System

This feasibility study will develop and evaluate pathways to identify participants with wearable-detected absoulute Arrhythmia (AA) and to enable local study teams to contact them regarding participation in a controlled trial of oral anticoagulation in this population, which will be conducted after the feasibility study.

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

In this study, the feasibility of evaluating the efficacy of a cloud based analytic service in combination with a PPG-wearable in detecting AA will be assessed and the number of cases found. The design aims to provide simple, low-threshold access to this screening technology targeting at-risk populations. This study will not cause any restrictions on the usual care of the study participants. Access to the screening will be provided close to home and free of charge. The app will also be used to validate and enhance the clinical information about the participants captured during the study. This information will be used to define and refine target groups with highest screening efficiency and, in the long-term, outcome benefits. The study will describe the prevalence of AA in an unselected population that can be reached by a low-threshold screening procedure. The study will also generate important information on the different possible screening environments in different countries (e.g. pharmacies, GP practices, etc). Structures of work-up and continuous patient management in screen-positive individuals will be described and may help to design screening pathways in the main trial. By verifying the wearable-diagnoses by ECG in all screen-positive and a random selection of screen-negative participants, the diagnostic accuracy of the wearable in combination of cloud based analytic service can be estimated. Cost effectiveness assessment will evaluate the cost of low-threshold remote screening per patient identified and help guide to target high risk groups with optimal screening yield in the future. The collected data will provide the sound basis for the design and conduct of a large outcome trial.

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 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.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: only control group
To investigate the specificity of the wearable and to gather more information on ECG abnormalities in the population studied, a randomly selected group of participants without wearable-detected AA within 8 weeks of screening (same number as screen-positives and verified by Telecare) will also be invited to obtain a 14day Tele ECG (patch).
