Wide Scale Monitoring for Acute Respiratory Infection Using a Mobile-Based Study Platform

March 4, 2022 updated by: John Brownstein, Boston Children's Hospital
This is a prospective observational study using a mobile study platform (app) that is designed for use on Android phones. Study participants will provide baseline demographic and medical information and report symptoms of respiratory infection on a weekly basis using the app. Participants will also report use of prevention techniques on the weekly survey. Mobility data will be collected passively using the sensors on the participant's smartphone, if the participant has granted the proper device permissions. The overall goals of the study are to track spread of coronavirus-like illness (CLI), influenza-like illness (ILI) and non-specific respiratory illness (NSRI) on a near-real time basis and identify specific behaviors associated with an increased or decreased risk of developing these conditions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The study population will be adult Android mobile device users who live within the United States.

Description

Inclusion Criteria:

  • Adult 18 years or older, Android mobile phone user, Resides in the United States (has a US home address)

Exclusion Criteria:

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
Incidence of influenza-like illness (ILI) and COVID-like illness (CLI) in a study participant.
Time Frame: 6-month participation period
The definition of ILI will be adapted from CDC guidelines as a participant reporting fever in addition to cough or sore throat without any other known cause. All study analyses and outcomes will be reported using federated analytics. Federated analytics utilizes aggregated responses, rather than individual subject reports. Due to this, when reporting the final outcome, the total incidence may not add up to exactly 100%.
6-month participation period
Incidence of COVID-like illness (CLI) in a study participant.
Time Frame: 6-month participation period
CLI will be defined as fever and cough, or shortness of breath, or loss of smell. Incidence will be defined as reporting of the above symptoms in the 7 days prior (and not previously). All study analyses and outcomes will be reported using federated analytics. Federated analytics utilizes aggregated responses, rather than individual subject reports. Due to this, when reporting the final outcome, the total incidence may not add up to exactly 100%.
6-month participation period

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
Disease Prevalence
Time Frame: 1-year study period
Patterns of mobility (e.g. time away from home, use of public transportation), and reported use of prevention strategies such as wearing a mask and social distancing in participants who do, or don't, develop CIL and/or ILI will be compared. All study analyses and outcomes will be reported using federated analytics. Federated analytics utilizes aggregated responses, rather than individual subject reports. Due to this, when reporting the final outcome, the total prevalence may not add up to exactly 100%.
1-year study period

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 4, 2020

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
