Healthcare systems are one of the essential systems in 2020, with Covid-19 cases increasing day by day are increasing the load on the healthcare systems. Blockchain, one of the most beautiful technologies of the modern era, can provide an efficient, feasible and easy solution to many healthcare system problems we face today.
Some of the problems we face today related to healthcare are record management, insurance claim processes, accelerated bio-medical research etc.
This figure shows the basic working of blockchain in the healthcare system.[ref-IEEE computer society]
USES IN DIFFERENT ASPECTS OF MEDICAL SYSTEM
Using blockchain to maintain and exchange medical records for research or other purposes will be more secure as blockchain records are immutable and secure. The source of these records will be verifiable and cannot be faked. The data can be secure as the blockchain will encrypt the data, and it can only be decrypted using the key which only the owner of the record has.
Enhanced insurance claim process-
An important goal is to verify the claim transactions to support health care financing tasks (i.e., health plan claims), such as preauthorization payment, alternative payment models, automatic claims using Fast Healthcare Interoperability Resources and smart contract, and Smart Health Profile to help manage the constant exit and re-entry of Medicaid beneficiaries due to eligibility changes. It also removes intermediate operations in the claim verification process. It is immutable, which makes it secure.
Accelerated bio-medical research-
Several researchers also propose accelerating secondary clinical data use using blockchain technology, including MedRec, Data Lake, Healthbank, and blockchain-based data-sharing networks. Also, ModelChain adopted blockchain to increase the security and robustness of the distributed privacy-preserving health care predictive modelling across multiple institutions.
