Health care is, to our knowledge, the only high-risk industry where rehearsals are not yet part of daily work. Medical education has long relied on an apprenticeship model often called see one, do one, teach one. With the development and growth of health care simulation, we can put an end to this model and provide an opportunity to rehearse high-risk, complex, and rare surgical procedures in a safe environment: on a simulator, not an actual patient. Rehearsal is the act of practicing an activity before going live, so to speak. A simulation-based clinical rehearsal (SbCR) refers to practice by clinicians for a generic or patient-specific procedure before actually providing patient care.1 This article provides elements that should be determined before implementation of effective SbCRs.
