Once launched, web applications are often embedded within an iframe of the main UI. WhyĬlinical workflow systems (such as EHRs) may be able to launch SMART applications in a few different ways: automatically at specific points in the workflow, by user interaction in the UI, or in response to a suggestion from a CDS Hooks Service (or other decision support service).
