ERresident

ERresident is a term used to refer to a physician-in-training in the field of emergency medicine who is enrolled in a residency program at a hospital's emergency department. The term blends the common abbreviation for the emergency room (ER) with resident, reflecting its use in medical education and clinical settings. In practice, ERresident is often used interchangeably with "emergency medicine resident" and appears in hospital rosters, curricula, and scholarly articles.

In most health systems, an ERresident has completed medical school and is in a postgraduate training program that prepares them to manage acute presentations across a broad range of conditions. US programs typically span three to four years and may require an initial internship year. During training, ERresidents perform triage, conduct primary and secondary surveys, initiate resuscitation, order and interpret tests, perform procedures (eg, airway management, intravenous access, wound closure), and coordinate disposition under the supervision of attending physicians. They work in shifts that include nights and weekends and participate in teaching and quality-improvement activities.

Board certification in Emergency Medicine (e.g., ABEM or AOBEM in the United States) is common after completion of residency. Training emphasis includes patient safety, clinical decision-making, team-based care, and practice standards. International models vary, with different lengths and accreditation processes. The ERresident role is central to ED operations and patient care, serving as a bridge between medical school training and independent practice as a board-certified emergency physician.
