Preoperative anxiety is a major concern for patients who undergo surgery. To accurately identify anxious patient is therefore crucial to improve perioperative patient care. Preoperative anxiety remain highly difficult to quantify in current practice. Many patient fail to express their anxiety and the assessment of the level of anxiety is mainly based on heteroevaluation by caregivers. Nurse anesthetists provide closed support to patient prior to the induction of anesthesia. The aim of the study is to assess whether nurse anesthetist accurately assess patient preoperative anxiety from arrival to the operating room to the induction of anesthesia.

EVALANXI is a single-center prospective observational study. The main objective of the study is to assess whether the assessment of preoperative anxiety by nurse anesthetist (hetero-assessment) accurately estimate the level of anxiety reported by the patient from arrival to the operating room to the induction of anesthesia (self-assessment).
