Typically, when a healthcare provider fails to give reasonable treatment to a patient which could causes injury, death or overcharges then its termed as medical malpractice. The medical negligence and cut practice are prevalent in developing and developed societies in one form or other. In the past there has been unfortunate case where doctors pretend to give treatment to an already expired patient to overcharge and even in some cases hospital authorities try to influence postmortem reports in their favor to avoid any medico-legal case. This paper attempts to provide a solution to restrict such medical malpractices in case of critically ill patients admitted to ICU having cancer, heart attack, coronary bypass surgery etc. The paper suggests building a permissioned private Blockchain solution with the help of Cloud, IoT, wearable devices and smart medical devices fitted with sensors. The Cloud based system will receive vital health parameters of patient with help of wearable and sensors devices on regular interval of time which is configurable and append new hash block to immutable Blockchain ledger using cryptographic hash function. It will provide role-based access to all the ecosystem partners for due diligence in the case of any unfortunate events.
