Aviary: Clinical Collaboration Platform

This talk will focus on the application development platform developed by our team at UHN. Our primary goal is to provide the ability to rapidly implement new forms and workflows without introducing downtimes. The user interfaces are composed from reusable components, and can be assembled with minimal involvement from technical resources using our Domain Specific Language (DSL) for defining screens and business logic.

Presented at Clojure/north 2019.

Transcript

1. Project Aviary A clinical collaboration platform
2. Who are we? Carmen La - Software developer at University Health Network - Author of Cryogen static site generator Dmitri Sotnikov - Software developer at University Health Network - Author of Luminus Framework and Web Development with Clojure
3. University Health Network
4. Clinical workflow • Patients typically have a circle of care
5. Server-side rendering Client Server View State Business logic
6. Single Page Application Client Server View State Business logic Service API REST/GraphQL
7. State Business logic View WebSocket View Our Approach
8. Let’s do it live! (nothing could possibly go wrong)
9. Language & Architecture
10. Data Driven Behaviours Document state Business rules UI rules View
11. Alternate implementations HTML Widgets React Native Widgets
12. Easily extensible
13. Reusable components
14. Formalized behaviors
15. Data governance • Data is collected to be analyzed • Separation of UI model vs at rest model ◦ UI model represents the view ◦ At rest model (HL7 FHIR) • Users of data ◦ Aidbox Clinical Data Repository ◦ Education/research needs health-samurai.io/aidbox
16. Data governance • FHIR has a larger scope than any one application • Application specific data model • Flexible mapping and transformation DSL • Resilient to changes in FHIR github.com/HealthSamurai/ironhide
17. • Data driven DSLs are flexible • Formalized behaviors are easier to maintain • Separate UI model from the at rest model Conclusions
18. Q & A
