NCT06207929

Brief Summary

The goal of this decentralized, observational study is to enroll and observe adults in the contingent United States during the 2023-2024 flu season. The main study objectives are to create a dataset of paired wearable data, self-reported symptoms, and respiratory viral infection (RVI) from PCR testing during the 2023-2024 flu season and to develop algorithm that is able to accurately classify asymptomatic and symptomatic RVI and understand the algorithm's performance metrics.

Outcome Measures

Primary Outcomes (1)

  • The primary objectives are to develop a dataset of paired wearable data, self-reported symptoms, and confirmed respiratory viral infection and use the dataset to develop an algorithm to classify asymptomatic/symptomatic RVIs

    This study will gather wearable device data, including heart rate, sleep, activity, and other data types from commercially available wearable activity trackers and smartwatches (e.g. Apple Watch, Fitbit, Garmin devices), as well as self-reported data related to the experience of symptoms associated with respiratory viral infections, and pair this data with the results from PCR tests of serial at-home nasal swabs for SARS-CoV-2, Influenza A, Influenza B, and respiratory syncytial virus (RSV). This data will be used to determine if these data types can be used to develop an algorithm for classifying asymptomatic and symptomatic RVI. Algorithm performance will be assessed across a variety of dimensions including ROC AUC, sensitivity, specificity, PPV, and NPV.

    Through study completion, approximately 10 months

Secondary Outcomes (1)

  • The secondary objective of this observational study is to determine if algorithm performance differs across various demographic groups

    Through study completion, approximately 10 months

You may qualify if:

  • Lives in the United States
  • Speaks, reads, and understands English
  • Currently owns and uses a consumer wearable device (Apple Watch, Garmin, or Fitbit) with necessary step and heart rate data at minimum or willing to wear a study-provided device and download the Fitbit app
  • Willing to connect their wearable device to the Evidation platform and wear it daily for at least 10 hours for the duration of the study

Biospecimen

Retention: SAMPLES WITHOUT DNA

All valid specimens will be tested using RT-PCR via the Abbott Alinity m Resp-4-Plex assay. A subset of individuals selected by the study team will be asked to provide saliva samples after enrolling in the study using the Spectrum MAXSwab Saliva Collection Device. Saliva samples may be shipped to another lab for processing and may be stored indefinitely. Valid saliva samples may, or may not, be tested for IgA and IgG at a to be determined lab.
