**6. Patient evaluation**

The preparation and precautions for endoscopy procedure are essential for patient safety. In order to reduce incidents, every patient should be comprehensively evaluated before GIE. The American Society of Gastrointestinal Endoscopy (ASGE) recommended that the initial endoscopic procedure is confirming the correct patient and procedure to be performed [21].

Before performing an endoscopic procedure, the patient's identity should be checked. Name and date of birth should be asked and checked on patients' wristband and medical record or document. The recommendations are confirming the patient by checking a minimum of two data: name and date of birth. The indication and type of the planned procedure should also be verified. The medical personnel, who will perform GIE, needs to deliver essential and relevant information related to the procedure to the patient. Informed consent has to be delivered in every endoscopy procedure [22].

Medical history might affect tolerance to the procedure. Patients' medical history needs to be checked thoroughly for the patient undergoing without sedation or with sedation, especially in moderate/deep sedation. The medical history will show the

presence of respiratory, cardiovascular, neurologic, renal, or other problems [22]. History of obstructive sleep apnea may predict ventilatory function disturbance with sedation [23]. Physical examination should be done, including vital signs, auscultation of the heart and lungs, a baseline level of consciousness, and assessment of airways [22].
