The smart hospital framework involves three main layers: data, insight and access. Medical data is collected real-time from devices and systems in a smart hospitals: the internet of medical things (IOMT). This data is integrated to provide insight from the analytics or machine learning software using digital twins. Security and transparency are brought through a combination of digital twins and blockchain technologies. Blockchain and Digital Twins for Smart Hospitals describes the role of blockchain and digital twins in smart healthcare. It describes the ecosystem of the IOMT, how data can be gathered using a sensor network, which is securely stored, updated and managed with blockchain for efficient and private medical data exchange. Together with its companion volume, 'Blockchain and Digital Twins for Smart Healthcare', the book offers insight to aid faster, smarter decisions with more efficiency to improve care for the patient.
