Does a nation like India with 1.3+ billion population need a healthcare system where health data of each citizen can be safely stored and readily accessed? Undoubtedly yes. Does there exist technology to do such a humungous task? Let us assume it does. Has it been done at this scale? No, it has not been done at such a large scale. There are examples like Estonia and few more pilot projects where all the healthcare data services are transferred to a futuristic digital system called Blockchain which is secure, easily accessible, and introduces accountability to healthcare system. Imagine a patient file which is written with a permanent marker, is password protected, records the names of everyone who has opened or edited the file, and is available wherever whenever needed. Imagine a tablet of paracetamol that comes with the information about its manufacturing location, date and time stamp, the person handling the drug, the supply chain information, and all this information is legitimate. Imagine an insurance claim filed for a surgical procedure, the details are automatically pulled for the patient file written with the permanent marker, and there is negligible possibility of a fraudulent claim. These are all examples of benefits of Blockchain in Healthcare. The underlying technology is to collect the data in real time, store it on multiple servers to make it hack resistant (nothing is hack proof), allow the access to authorised people only, and store a newer version every time the file is accessed.
