MedPath is a domain-specific language created by Intmed, a Brazilian health tech company, to model and design care pathways using Model-Based Systems Engineering (MBSE) and the Sirius modeling tool. MedPath allows experts to collaboratively design pathways that are then interpreted and executed through MedPath's dashboard and system. The pathways can be rapidly updated and shared to guide doctors and improve patient care. Intmed has used MedPath to model over 200 care protocols for various medical specialties and conditions, including COVID-19. Evaluations found Sirius to be a good fit for quickly constructing and evolving their DSL and integrating pathways with legacy systems through interpretation.

22. How Sirius is being used
Expert doctors acquainted with the process
- They still leave details as comments
- Tend to be very busy
Process Engineers (Production Engineers)
- Talk to the doctors, model and then validate

23. Feedback, review and prospects
Sirius proved itself a nice fit for rapid construction and evolution of our
DSL
Having the care pathways as a "document" allowed us to version,
verify and correctly share it throughout the process (model as
first-class citizen)
23

24. Feedback, review and prospects
We started the project in 2017, we believe now we can explore the Web
capabilities of it
Interpretation, instead of compilation, allowed us to easily integrate to
existing legacy systems
Data storage and load was challenging
