ACCESS (American COVID-19 Collaborative, Enabling Seamless Science) Master Digital Surveillance and Associated Clinical Trials Protocol for COVID-19

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

ACCESS enables individuals to contribute to critical research, via an iOS and Android smartphone mobile application. ACCESS combines patient reported outcomes, data from wearable devices and real-world data (such as claims, EHRs, etc), with an opt-in to participate in current and future studies for diagnostics, treatments and vaccines. The data that people share can be quickly and anonymously matched to research studies, providing researchers with a foundational framework for dynamic research at scale and participants a way to be personally matched and prescreened for future research.
