Client's Testimonial
In our world, data integrity is not just a compliance issue-it's a matter of patient safety. Developers.dev built a blockchain solution that provides an immutable, auditable trail for every piece of clinical data. Their understanding of healthcare regulations and their meticulous, process-driven approach gave us the confidence to deploy this in a live trial environment.
Client Overview
A mid-sized pharmaceutical company specializing in oncology research. They faced challenges with data integrity during multi-site clinical trials. Data was recorded in disparate systems, leading to reconciliation issues, potential for tampering, and delays in regulatory reporting to bodies like the FDA.
Problem
The process of collecting, sharing, and verifying data from multiple clinical trial sites was slow, manual, and prone to error. The client needed a way to prove to regulators that the data had not been altered from the moment it was recorded.
Key Challenges
Regulatory Compliance:
Needed to comply with strict healthcare regulations like HIPAA and 21 CFR Part 11.
User-Friendly Interface:
Ensuring the system was easy to use for clinical staff who were not tech-savvy.
Immutable Data Log:
Creating a permanent, immutable log of all data entries and modifications without storing sensitive Patient Health Information (PHI) directly on the blockchain.
Integration with CTMS:
Integrating with existing clinical trial management systems (CTMS).
Our Solution
We developed a "Healthcare Records Ledger" using a private Hyperledger Fabric network. The solution did not store the raw patient data on-chain; instead, it stored cryptographic hashes (digital fingerprints) of the data along with a timestamp.
Data Hashing
When a record was created or updated in the site's local database, a unique hash of that record was generated and stored on the blockchain. This created an immutable, timestamped proof of the data's existence and state at that exact moment.
Audit Trail
Anyone could verify the integrity of the data by re-hashing the source record and comparing it to the hash stored on the blockchain. Any mismatch would instantly prove that the data had been tampered with.
Permissioned Network
Only authorized parties (e.g., the pharma company, clinical sites, regulators) were given access to the network, ensuring complete privacy.
Simple Integration
We provided a simple API that integrated with the existing CTMS, running in the background to automatically hash and log data without changing the workflow for clinical staff.
Implementation and Execution
Regulatory & Compliance Workshop
The project began with our "Data Governance & Data-Quality Pod" and legal experts mapping out all regulatory constraints.
Architecture Design
We designed the "hashing and anchoring" architecture to ensure compliance and data privacy.
Prototype Development
We built a working prototype in four weeks to demonstrate the concept to the client's compliance and IT teams.
API Development & Integration
Our team built a robust API and worked on-site with the client's CTMS vendor to ensure seamless integration.
Rigorous Validation & Testing
We conducted extensive testing and validation to document that the system met all requirements of 21 CFR Part 11 for electronic records.
Staged Deployment
The system was first deployed to two trial sites in the US, then expanded to 15 sites across the US and EU after a successful validation period.
Positive Outcome
100% Data Audibility
The client could now provide regulators with a verifiable, timestamped audit trail for every single data point, dramatically speeding up audits.
Reduced Data Reconciliation Time by 80%
The single source of truth for data integrity eliminated the time-consuming process of cross-referencing logs from different sites.
Enhanced Trust with Regulators
The proactive adoption of this technology demonstrated a commitment to data integrity that was highly valued by regulatory bodies.
Zero Change in Workflow for Clinical Staff
The background operation of the system meant no additional training was required for site staff, ensuring rapid adoption.
