On February 23, 2021, NHSX launched Digital Technology Assessment Criteria for health and social care (DTAC), the new national criteria designed to provide suppliers and healthcare organizations a clear direction on building and buying good digital health technologies. DTAC will apply to all types of digital health technologies, from public-facing health apps to digital systems used within hospitals. The assessment criteria are focused on five areas: digital technologies will receive a pass or fail in four categories - clinical safety, data protection, technical security and interoperability, and a score on usability and accessibility.
