Healthcare Records: Blockchain Consultation for Multi-Clinic Network

A healthcare network operating 18 clinics across three regions contacted us about patient data sharing. Their challenge was specific: doctors needed access to complete patient histories while maintaining strict privacy controls and regulatory compliance.

Compliance Audit

Examine regulatory requirements before technical decisions. We reviewed GDPR provisions, local health data laws, and documented which patient information could be stored on-chain versus off-chain. Medical imaging and detailed notes would remain in traditional encrypted databases, while access permissions and record hashes would live on the blockchain.

Architecture Design

Define the network structure matching organizational hierarchy. We proposed a private consortium blockchain where each clinic operates a node. Patients would control access through cryptographic keys, granting or revoking permissions for specific providers or time periods.

Vendor Evaluation

Compare platforms against the healthcare network's technical and budgetary constraints. We tested three enterprise blockchain solutions with their IT team, measuring transaction throughput, storage costs, and integration complexity with their existing patient management software.

Implementation Roadmap

Create a phased rollout plan with measurable checkpoints. Our consultation delivered a 14-month timeline, starting with two pilot clinics, followed by regional expansion, and concluding with full network integration. We identified 23 integration points requiring custom development and estimated ongoing operational costs at approximately 6,800 euros monthly.
