Comparing Phoneme Speech Recordings and Acoustic App Data Capture Experience for Android and iOS Mobile Device Users in the Large Decentralized AcRIS Study
Chappie et al.
The finding, in our words
The study found that acoustic speech features differed significantly between Android and iOS devices, with iOS recordings showing more periodic content but less high-frequency energy, while Android devices exhibited greater measurement variability. These platform-specific differences, coupled with participant experience challenges such as iOS users struggling with background noise checks, demonstrate that device choice and app instruction design materially affect data quality and trial outcomes in decentralised digital biomarker studies.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
A direct-to-participant, multichannel recruitment strategy enrolled 34,244 older adults into a virtual trial testing an Apple Watch based heart health programme with electrocardiogram and irregular rhythm notification features, achieving broad geographic and gender diversity but under-representing non-White ethnic groups.
Home spirometry gave slightly lower percent-predicted FEV1 values than office measurements cross-sectionally, but the three-month change in lung function did not differ significantly between settings. This suggests home spirometry can reliably detect treatment effects, supporting its use as an endpoint for decentralised cystic fibrosis trials.
Wearable-derived digital biomarkers have been accepted by regulatory agencies as endpoints in clinical trials for Duchenne muscular dystrophy, showing their potential to support decentralised diagnostics through patient-centric monitoring. This matters because it enables more sensitive and continuous assessment of disease progression outside clinical settings.
A randomised trial of 47 participants using a mobile app integrated with remote patient monitoring devices achieved a 74% biomarker submission rate over four weeks, with system usability scores of 77–94 and acceptability exceeding benchmarks, showing the platform is feasible for remote data collection in decentralised clinical trials.
This study found that a decentralised approach using home-based sleep apnoea screening, heart rhythm monitoring and activity tracking in patients with atrial fibrillation is feasible, with high data completeness and low drop-out rates. The results support the use of patient-centric digital tools in decentralised trials for chronic cardiac conditions.
