COVID‑19 Automatable Guidelines
With the coronavirus pandemic rapidly evolving, healthcare workers in the trenches need to efficiently and effectively diagnose and treat COVID‑19. Evidence-based content and best practices related to COVID‑19 are appearing and changing every day. Using Trisotech Digital Modeling Suite it is possible to very rapidly capture this constantly evolving knowledge with simple to understand visual models known as Automatable Guidelines. These Decision and Course of action Models not only unambiguously communicate the best practices, they are directly automatable using Trisotech Digital Automation Suite. If you want to find out more on this innovative technology please contact us.
