Discussing the details of a procedure (for example, endoscopy) with patients is often included in objective structured clinical examinations, and as a doctor you will always be required to inform patients sufficiently and involve them in decisions about any procedure they may require.
Introduce yourself appropriately to the patient, check if they have any prior knowledge of the procedure, if they have ever had the procedure before, or if they know someone who has. Then explain the purpose of the procedure, its approximate duration, and how they can expect to feel immediately afterwards.
Tell the patient:
Finally, answer any questions the patient might have, identify any concerns, and ensure all the information that you have provided is understood. Avoid using unexplained medical jargon.
