Standardized patients (SPs) are widely used in assessment; however, the majority of SP exercises involve “announced” encounters in which the learner knows that they are interacting with a simulated patient. While Objective Structured Clinical Examinations (OSCEs) are considered a gold standard for assessing clinical skills, their contrived nature may limit their ability to capture the true behaviors of medical professionals [1]. Unannounced standardized patients (USPs) are a relatively new, but increasingly employed, method of evaluating the skills of medical professionals [2, 3]. Unlike OSCEs, USP encounters are in situ assessments in which the learner is not aware that the patient is an SP. As such, there are no artificial time constraints nor potential for observation bias, and the USP can evaluate the in situ behaviors of clinicians and the clinical system. Other models to deploy SPs in the clinical setting include: remote visits and Announced Standardized Patients (ASPs) to assess or train health professionals or the clinical system.
