RESTful Health APIs Most are specific to a device/company (fitbit, misfit, withings, etc) …although… There are some general purpose APIs, like the Human API https: //www. humanapi. co/ These RESTful APIs have some common design features/flaws: • URL based on data type: – /user-id/sleep – /user-id/activity – /user-id/weight • Different data structures for each data type • Additional data types require API change! • Do not integrate easily with medical records (require translation) 2 Health.

How do we bridge the gap? 3 Health. Suite Hackathon
Enter FHIR http: //www. hl 7. org/fhir/ • A new standard – Made possible by new technologies and standards – Informed by lessons of the past • Not a new standard – We don’t need yet another health data standard – HL 7, the health data standard since 1987 • REST API • “Internet of Things” for your health data • your health data is now addressable • Compatible with wide range of data – Hospitals – Home Monitoring Equipment – Fitness Trackers – Environmental sensors 4 Health.

What is FHIR? A Brief History • Fast Healthcare Interoperability Resources (FHIR) RESTful API for health data • HL 7 standard with long history – HL 7 v 2: internal hospital data – HL 7 v 3: Health Information Exchange (HIE) – CDA/CCD: Clinical Document Architecture / Continuity of Care Document – FHIR: Simplified REST implementation of CDA 5 Health.

FHIR Basics • Everything is a resource – Organization – Patient – Observation Resources are connected with URL references 6 Health. Suite Hackathon Every resource is addressable with a URL https: //yourserver. com/Organization/123 https: //yourserver. com/Patient/456 https: //yourserver. com/Observation/789
Observation Resource “subject” is relative URL of the patient “value. Quantity” contains the value and units 7 Health. Suite Hackathon
Observation Timing “applies. Date. Time” Point in Time “applies. Period” Time Interval Observation Value • “value. Quantity” – Value – Units § SI - Système International d’Unités, or International System of Units § UCUM – Unified Code for Units of Measure 8 Health. Suite Hackathon
Coding the Observation Type LOINC – hospital / medical data IEEE-11073 – fitness, diet, environmental 9 Health. Suite Hackathon

Fitness Data • Nothing special about fitness data in FHIR • Observation with a code, same as everything else • IEEE-11073 covers fitness data – Steps per day – Sleep quality – And much more! 12 Health. Suite Hackathon
