# Embleema PatientTruth - Blockchain Platform for Patient Data Management

> Embleema developed PatientTruth, an Ethereum-based blockchain platform that enables patients to consolidate their health data from various sources while maintaining complete control over data sharing. The platform launched in July 2018 as a public beta after one year of development and allows integration of HL7 documents and Fitbit data. Patients can securely share their data with pharmaceutical companies and health authorities while receiving token rewards for their data contributions.

## Description

Embleema launched a blockchain-based platform where patients can securely store their health data and selectively share it for clinical research. The platform positions patients as active research partners rather than passive data providers.

The problem in clinical research: 80% of all clinical trials are delayed because not enough patients can be recruited in time. At the same time, millions of patients have health data relevant for research but no secure, transparent way to share it. Embleema solves both problems: patients create a blockchain-secured health profile; pharmaceutical companies and research institutions can make targeted requests (e.g., patients with a specific diagnosis, age group, medication history); patients explicitly decide whether to participate and which data to share. Smart contracts control data access; all accesses are logged and revocable. FDA engagement: Embleema data is directly recognised in the regulatory approval process — significantly accelerating market entry approval. PMC study (NCBI, 2024) on blockchain in the pharmaceutical industry identifies Embleema as a leading example of patient-centred research data.

## Benefits

- Companies can interact directly with patients and obtain high-quality data for clinical studies without complex intermediaries.
- Patients receive financial compensation for their valuable health data and can actively participate in medical research.
- Patients gain full control and ownership of their health data with the possibility of targeted monetisation.
- Blockchain technology ensures immutable audit trails and the highest data security for sensitive health information.
- Pharmaceutical companies gain ethically sound access to high-quality real-world data for accelerated research and development.
- Researchers and data analysts benefit from automated data access processes and can focus on their core work instead of administrative tasks.

## Challenges

- Pharmaceutical companies must fundamentally rethink their existing data management processes and invest in new blockchain infrastructure.
- Patients need to develop a basic understanding of blockchain technology and data protection to make informed decisions about sharing their data.
- The high technical complexity requires specialised blockchain developers with expertise in health data standards and data protection regulations.
- Acceptance among traditionally conservative healthcare organisations and integration into existing systems poses a significant challenge.
- Medical professionals must familiarise themselves with new blockchain-based systems and adapt their workflows to decentralized data structures.

## Technology foundation

The platform is based on the Ethereum blockchain and uses smart contracts to manage data access permissions and authorisations. This technology is particularly well suited for health data as it enables an immutable audit log of all data accesses and gives patients full control over their data.
