Summary Background:  Objective structured clinical examinations (OSCEs) are a commonly used method of assessing clinical competency in health care education. They can provide an opportunity to observe candidates interacting with patients. There are many challenges in using real patients in OSCEs, and increasingly standardised patients are being used as a preference. However, by using standardised patients there is a risk of making the encounter artificial and removed from actual clinical practice. Context:  Efforts made in terms of cognitive, auditory, visual, tactile, psychological and emotional cues can minimise the differences between a simulated and real clinical scenario. However, a number of factors, including feasibility, cost and usability, need to be considered if such techniques are to be practicable within an OSCE framework. Innovation:  This article describes a series of techniques that have been used in our institution to enhance the realism of a standardised patient encounter in an OSCE. Efforts in preparing standardised patient roles, and how they portray these roles, will be considered. A wide variety of equipment can also be used in combination with a patient and the surrounding environment, which can further enhance the authenticity of the simulated scenario. Implications:  By enhancing the realism in simulated patient OSCE encounters, there is potential to trigger more authentic conscious responses from candidates and implicit reactions that the candidates themselves may be less aware of. Furthermore, using such techniques may allow faculty members to select scenarios that were previously not thought possible in an OSCE.
