Blockchain’s Promise for Healthcare: A Snapshot

Distributed ledger technology (DLT) is quietly reshaping health data sharing, security, and collaboration—and what’s next. A few years ago, I have presented a position paper at an international knowledge management conference. The paper 83489.pdf explores how blockchain and distributed ledger technology could secure and streamline healthcare knowledge management.

Why This Matters -Healthcare thrives on fast, accurate knowledge exchange. As patient data volumes surge, legacy systems struggle to keep pace. Blockchain and DLT offer a secure, transparent backbone that could (1) Unite disparate electronic health records without a central gatekeeper; (2) Give patients and providers fine-grained control over who sees and edits data; and (3) Embed trust through immutable audit trails and smart contracts

 Two Strategic Approaches - The paper defines two primary “schools of thought” for healthcare DLT: (1) Interoperability Catalyst Unlocks seamless data exchange across hospitals, labs, insurers Reduces dependency on costly, error-prone intermediaries, and (2) Privacy & Access Manager Acts as a permissioned gatekeeper for sensitive health records Complies with GDPR, HIPAA, and patient-centric consent models

Both converge on one goal: an integrated ecosystem in which data flow securely and efficiently. The result? Faster workflows, fewer duplicate records, and a single “source of truth.”

Challenges - Blockchain in healthcare is still emerging. Key hurdles include: (1) Managing cryptographic keys to avoid data loss; (2) Balancing transparency with confidentiality at scale; and (3) Designing governance for public vs. private DLT networks, and others

Looking Ahead - Can public ledgers fuel epidemic response? How might IoT-driven medical devices onboard securely? What governance models best protect patient rights?

Still to be seen and experienced!
