Octa Pillars-based Approach to Select the Best Blockchain-based Solutions in Healthcare Information Exchange

Nowadays, health care has become a constant concern of all countries around the world, especially after the emergence of the Coronavirus (COVID-19) and all its variants. Billions of dollars are being paid through the World Health Organization to improve health care. Scientific research laboratories play a pioneering role in this area as well. Due to the importance of information related to the patient and his medical history, it is necessary to exchange these information between various health centers in order to be better treated. Security in Health care information exchange (HIE) plays an important role because different healthcare facilities (HCFs) exchange sensitive data which can affect the patient’s privacy. Researchers propose many approaches in order to enhance security and maintain privacy. They also try to solve many drawbacks in this field like efficiency, accuracy, and scalability. Unfortunately, all the proposed techniques tackle some parameters and drop other ones. To decide which blockchain-based approach is more efficient for HIE systems, by evaluating each approach’s effectiveness based on its security, integrity, privacy, accuracy, scalability, efficiency, and latency qualities, we present a comparative analysis between a number of recent approaches in the HIE sector. Further, we use real patients’ data to measure each parameter, then we apply the Friedman test on the obtained results for each approach.
