In the case of CDS Hooks, in particular, it is noted that the CDS Hook display mechanisms support rules that determine where CDS Hooks cards are rendered in in the workspace shown on the user interface (UI). The mechanisms may be based on card attributes where the CDS Hooks standard supports the following indicators: (1) Information, (2) Warning, and (3) a Hard-stop. Additionally, the presently disclosed systems may support interruptive or active alerts such as pop-up of “Toaster” alerts for CDS Hooks following a prioritization of hard-stop indicators for active alerts notifications (i.e., pop-ups or other overlaying messaging) according to a “hard-stop rule”, whereas passive alert bar notifications are only provided for information and warnings. This prioritization and decision to show only certain higher priority CDS notifications serves to avoid “alert-fatigue” in the clinical user and is only to be interrupted for the most crucial or highest priority messages or notifications, with passive alerting via a motion-based icon display, as an example for the info and warnings.
