Question

When using BPMN to map a clinical workflow, what is the specific function of a &#x27;Boundary Event&#x27; when attached to a task involving a medication administration step?

Accepted Answer

In BPMN, a Boundary Event is a graphical element attached to the border of an activity, such as a medication administration task, to catch specific triggers that occur while that task is in progress. When attached to a medication administration task, its primary function is to handle exceptions or interruptions that occur before the task is completed. These events are categorized as either interrupting or non-interrupting. An interrupting boundary event stops the medication task immediately upon activation, redirecting the clinical process to an alternative path, such as moving to an emergency protocol if an adverse patient reaction is detected. A non-interrupting boundary event allows the medication task to continue normally while simultaneously triggering a secondary process, such as sending an automated notification to a pharmacist that a dose was administered. By using these events, a clinical workflow ensures that unexpected clinical scenarios are managed without abandoning the primary process flow.
