Blockchain Applications In The Medical Industry

By CIOReview | Friday, September 16, 2022

Blockchain has the potential to address issues with data storage and sharing in the healthcare sector, and successful implementation will require a thorough grasp of the technology's capabilities and use cases.

FREMONT, CA: Blockchain is a distribution ledger technology (DLT) that decentralizes data storage and sharing. Data storage and sharing difficulties are prevalent in healthcare since health information must be private and interoperable to accomplish desired outcomes. They enable users to record transactions in a shared ledger within that community under the normal functioning of the blockchain network. These qualities suggest blockchain could solve some of healthcare's data storage and sharing concerns, but understanding its potential and actual use cases is crucial for successful deployment.

EHRs and health data

Clinical decision-making depends on care coordination and connecting patient data across the care continuum. EHR interoperability and healthcare big data interchange are popular blockchains used in healthcare. A blockchain-based system allows consumers to approve EHR modifications, authorize new physicians to view their records and manage provider sharing. The strategy may also boost trust in data during care, which can affect clinical decision-making. Using blockchain, users could read and alter particular datasets, and all devices would have up-to-date information.

Blockchain affects healthcare data security

All health systems and companies prioritize data security, but the growing volume of data and questions about managing it are challenges. Blockchain means to mitigate the risk of many insecure gateways. Blockchain's immutable ledgers are updated simultaneously on all network nodes. It means there's no central gateway from which data is altered. Blockchains connect data "blocks" with unique signatures or "chains" If a block's data needs to be modified, a new block is inserted, not the old one. Blockchain prevents unauthorized data tampering and is difficult to hack because of its design. Developing blockchain-specific security and privacy protocols could pay off.

Fog computing and IoT

Healthcare IoT collects, analyzes, and uses patient-generated health data (PGHD). IoT gadgets like wearables, home scales, diabetes monitoring, telehealth tools, and mHealth apps cause PGHD. Unstandardized and poorly characterized data have the potential to improve clinical care. Many firms rely on cloud computing for real-time analytics, which uploads device data to the cloud. Relevant information is then found, processed, and presented to doctors. Fog computing can use to share health data across enterprises by turning IoT devices into small data centers. Patient health data can senD among devices using a fog computing system with set user and authorization policies.
