KeywordsPermissioned blockchain network emergency medical care scalable blockchain A B S T R A C TA relationship exists between the emergency patient death rate and factors such as the failure to access a patient's critical data and the time it takes to arrive at hospitals. The ability for Paramedics to access a patient's complete picture of emergency-relevant medical data is critical and can significantly reduce the annual mortality rate. Today, the problem exists with a continuous recording system of the patient data between healthcare providers. In this paper, we have introduced a blockchain-based solution to record patient emergency relevant medical data as patient walks through from one medical facility to another, creating a continuous footprint of patient as a secure and scalable data source. Therefore, ambulance crews can access and use it to provide high quality pre-hospital care.
