Prism and Janssen Clinical Innovation co-created an ontology of digital health technologies (DHTs) and piloted an algorithm that could automatically search and compile data on the clinical trial use for each unique device in the ontology. The first stages of this work were reported and published in August 2023. The vault dataset represents the next stage of this work: Prism has developed technology that can automatically retrieve data and generate an analysis for every element in the DHT ontology—that is, every DHT class, subclass, manufacturer, measurement component, and individual device has a unique page in the vault.
