We are a similar size ER. We started using ESI this past spring. The way our flow works is that patients present their name and cheif complaint to registration clerks/greeters. That information is entered into our computerized tracking board. We use two triage nurses from 9am until 11pm. Patients with chest pain and other more serious complaints are triaged before less serious complaints. We practice comprehensive triage, including institution of standing orders. If a bed is not immediately available for a patient triaged ESI 2, we initiate EKG, labs, heparin lock, ASA, etc. in the adjoining sub-acute area until a monitor bed is available. Medical screening exams are done by physicians and mid-levels when patients are "seen." That is our main problem now, because during high volume times, patients triaged ESI 2 can wait 4 hours to be seen. We simply need more physicians and mid-levels to see patients and get them dispositioned.
