Even before starting your evening shift you know it's going to be busy. Ambulances are lined up in front of the hospital, and the charge nurse already seems stressed out. The senior Emergency Medicine (EM) resident is standing in the physician office, ready to start her shift as well. You have worked with her a few times during this rotation. She is competent, you trust in her management plans for all her individual patients. Together you both review the patient tracker: a variety of patient presentations ready to be seen, plus an additional 20 patients in the waiting room. Negotiating the learning objective for the shift, the resident indicates that she would like to work on more efficiently managing patient flow and the administration of the emergency department (ED). But…isn't that a skill you just learn from experience? You wonder what evidence-informed strategies might exist for training her for this next step.
