Patient’s point of entry

This illustration shows pathways to a patient’s point of entry into a system of care, or SOC, during a cardiac emergency. The illustration is built around a horizontal line with four nodes on it. From left to right, the nodes are labeled “Event,” “9-1-1”, “E.D.” (for “Emergency Department”), and DC. Three overlapping circles are overlaid on this line. The circle on the far left is red, and it encompasses the first two nodes: Event and 9-1-1. The circle is labeled “Community SOC.” Text that says “Bystander Witnessed” has an arrow pointing to this circle. This indicates that when the cardiac emergency is witnessed by a bystander, the patient’s point of entry is via the Community system of care. The middle circle, which is blue, encompasses the second two nodes: 9-1-1 and E.D. This circle is labeled “Out-of-Hospital SOC.” Text that says “EMS Witnessed” has an arrow pointing to this circle. This illustrates that when the cardiac emergency is witnessed by EMS, the patient’s point of entry is via the Out-of-Hospital system of care. The circle on the far right, which is green, encompasses the last two nodes: E.D. and DC. This circle is labeled “Hospital SOC.” Text that says “IHCA” (for “in-hospital cardiac arrest”) has an arrow pointing to this circle. This signifies that when the cardiac emergency occurs while the patient is hospitalized, the point of entry is via the Hospital system of care.
