All plants are producers, or autotrophs, which means they create their energy (or food) through a process called photosynthesis. In this lesson, we characterize producers by 3 main traits: producers make their own food; producers cannot physically move; and producers provide food and shelter for animals.
The Emergency Severity Index (ESI) is a five-level tool for use in emergency department (ED) triage. Experienced ED nurses use the ESI to rate patient acuity, from level 1 (most urgent) to level 5 (least resource intensive). The ESI is unique among triage tools, by including both acuity and resource needs in the system of categorizing ED patients.
ESI-2 and 3 patients, who represent the majority of patients at large academic hospitals (e.g., about 80% at the University of Michigan ED (UMED)), are served in the main area of the ED with priority given to ESI-2 patients. Since the ESI system does not di erentiate between patients in the ESI-2 and ESI-3 categories in terms of complexity, patients in the main ED are still sorted and prioritized purely on the basis of urgency. Hence, the. ESI system does not respond to the second purpose of triage for the majority of the patients.
