Like many of you, I’ve worked for many companies over my career. In that time, I’ve had multiple health, vision and dental insurance providers, and visited many different clinics, hospitals and labs to get procedures & tests done.

Recently I had a semi-serious medical issue, and I realized that my medical history (and the medical history of my family members) is a lot more complicated than I realized and distributed across the many healthcare providers I’ve used over the years. I wanted a single (private) location to store our medical records, and I just couldn’t find any software that worked as I’d like:

  • Self-hosted - this is my medical history, I’m not willing to give it to some random multi-national corporation to data-mine and sell
  • All inclusive - It should aggregate my data from multiple healthcare providers (insurance companies, hospital networks, clinics, labs) across multiple industries (vision, dental, medical) – all in one dashboard
  • Automatic - It should pull my EMR (electronic medical record) directly from my insurance provider/clinic/hospital network - I don’t want to scan/OCR physical documents unless I have to
  • Open-source - The code should be available for contributions & auditing

So, I built it.

Fasten is an open-source, self-hosted, personal/family electronic medical record aggregator, able to integrate with the electronc medical records your healthcare providers & insurers are already using.

Fasten is designed with a solid foundation that is easily extensible:

  • Self-hosted
  • Designed for families, not clinics (unlike the EMR your doctors use)
  • Supports the FHIR protocol required by U.S. law
  • Uses OAuth2 (Smart-on-FHIR) authentication, so you don’t need to trust Fasten with your password
  • Uses OAuth’s offline_access scope (where possible) to automatically pull changes/updates
  • Multi-user support for household/family use
  • Dashboards & tracking for lab work, panels, & vitals
  • Ability to manually add data from paper charts or self-ordered lab work
  • (Future) Integration with smart-devices & wearables
