Improving Recruitment Efficiency with Wearable Devices

By utilizing wearable devices before trial participation, we conduct pre-screening and obtain highly reliable data in advance, significantly increasing eligibility rates. For trials that require testing at medical facilities prior to participation, we identify and introduce highly suitable candidate participants. This helps reduce the workload and costs associated with screening as well as the burden on participants.
