MediLOT is a dual blockchain based EHR ecosystem with a unique layered architecture that incorporates machine learning and data analytics capabilities on top of its control and data layers, allowing machine learning APIs with complex applications to be built on top of the system.
By having a distributed ledger (Hyperledger++) that records all the transactions, the entire longitudinal patient data can be retrieved at any time by authorised healthcare practitioners for clinical use. These health records are then accessible, with permission by patients, across different institutions. For example, a patient who visits a hospital he has never been treated at previously will not be required to repeat investigations, as the doctor or clinician who has been granted access rights can access his entire health record via MediLOT. Furthermore, differential consent choices, such as those involving organ donation, advance medical directives and research, can also be recorded on the blockchain and accessed universally. Specifically, consent choices involving the use of data for research can be captured in a granular manner, allowing researchers to immediately discern if patients consent for their data to be used for research, including the use of their biological material, as well as whether re-identification is allowed should there be a need.
