Typical ER Wait Time in Delaware
On this page
A typical emergency room visit in Delaware takes 3 hours 37 minutes from arrival to going home. That is 55 min longer than the U.S. median of 2 hr 42 min. Half of visits are shorter and half are longer. The figure covers Oct 2024 to Sep 2025, the latest published.
This is the length of the whole visit for patients who were treated and sent home: waiting, tests, treatment and discharge together. It is not the wait until a doctor sees you, which is not published by state.

What this figure is
Hospitals report to the Centers for Medicare & Medicaid Services how long patients spend in their emergency departments. The figure here is CMS measure OP-18b: the median time from arrival to departure for patients who were sent home. Patients who were admitted, transferred to another facility, or seen for psychiatric or mental health care are left out of it.
It is a statewide figure over twelve months. A single hospital, a busy evening or a serious case can be far from it, and it says nothing about any one emergency room tonight. In an emergency, call 911 or go to the nearest emergency room.
