On Components of a Patient-centered Healthcare System Using Smart Contract

In this paper, we propose a patient-centric care system based on a smart contract mechanism which is an enhancement to Blockchain technologies. The health records are controlled by the patients, it means the patients could choose and share what kind of information related to their health history to the clinics even the sensitive information. The secure information mechanism and e.ective technical infrastructures to enhance care coordination of individuals and communities are achieved by using Smart Contract which is implemented on Hyperledger Fabric and Ethereum Blockchain. Six algorithms were utilized for interacting data between the components of a Patient-centered healthcare system: createData(), query-Data(), get.eryHistory(), createPatientInformation() / createMedicalRecord() / createDrugInformation() / createHospitalFees() and modifyPatientInformation() / modifyMedicalRecord() / modifyDrug-Information() / modifyHospitalFees(). The simulation results show that the healthcare system and record resources consumption by the aforementioned six algorithms, in terms of execution speed and memory capacity that are allocated for each function at the execution time ranges from 1s.
