About This MicroSim

This diagram shows a clinical care pathway modeled as a directed acyclic graph (DAG): eight stages, from patient admission through discharge planning, connected by directed arrows that always move forward in time. The single dotted edge — re-testing when results are inconclusive — loops back only to diagnostics, never to admission, illustrating the defining DAG property that a patient does not cycle back to an earlier stage within one encounter.

How to Use

Follow the solid arrows through the eight numbered stages to trace the normal forward flow of an encounter. Note the dotted red "re-test if needed" edge, which is the one conditional path, and read the annotation explaining why the pathway is acyclic — a structure that lets graph databases reason about ordering and progress without infinite loops.
