The primary benefit of blockchain technology in healthcare is its ability to enhance data security, transparency, and interoperability across systems. By using a decentralized ledger, healthcare entities can securely store medical records, ensuring that sensitive data is accessible only to authorized personnel while being resistant to tampering. This fosters trust among patients, providers, and payers. Furthermore, blockchain enables seamless sharing of patient information across different systems, which enhances care coordination, reduces administrative burdens, and potentially lowers healthcare costs.
