## Description

Patientory was founded in 2015 by Chrissa McFarlane in Atlanta and quickly became one of the best-known healthcare blockchain projects. The ICO in May/June 2017 was one of the first ever for a healthcare company. The PTOY token functions as the access currency to the PTOYMatrix — Chrissa McFarlane: The first blockchain ICO in healthcare.

Patientory solves the fundamental problem of healthcare data interoperability: patient data is stored in silos — different clinics, practices, and labs have incompatible systems and no secure data exchange paths. Patient data breaches cost the US healthcare industry 10.9 billion USD annually. PTOYMatrix is a private, HIPAA-compliant blockchain network: patients create profiles with their medical history; doctors and clinics receive only the access explicitly authorised by patients; all accesses are immutably logged. The PTOY token has two functions: as a usage fee for the platform and as an investment asset. Neith Enterprise: enterprise product for clinics for population health analytics. Boomtown Health-Tech Accelerator (Boulder, 2016): Patientory was in the founding class. Partners: Kaiser Permanente (Colorado Permanente Medical Group), StartUp Health.

## Benefits

- Healthcare providers can unlock new revenue streams of over 4 million USD through improved data interoperability and pharmaceutical collaborations.
- Patients receive token rewards for active participation in their healthcare and retain full control over their data.
- The platform enhances patient engagement through token rewards and has already reached over 45,000 subscribers.
- Secure, HIPAA-compliant data management ensures the highest data protection standards in healthcare.
- Comprehensive data integration from over 24,000 health systems enables complete patient overviews.
- Medical staff make more informed treatment decisions through better access to complete patient data.

## Challenges

- Healthcare providers must make significant investments to integrate with existing IT systems.
- The high technical complexity requires comprehensive integration with existing healthcare systems.
- Scaling to a large number of participants while maintaining HIPAA compliance presents ongoing challenges.
- Staff require extensive training to handle the new blockchain-based platform.

## Technology foundation

Patientory uses its own private blockchain solution called PTOYMatrix Blockchain Storage Network, which is HIPAA-compliant and enables decentralised apps for storing patient data. This technology encrypts health data and distributes it decentralised, allowing patients to retain control over their data while maintaining the highest security standards in healthcare.
