About this study
Official title: Behavioral Markers of Pre-operative Anxiety : a Prospective Observational Study in Ambulatory Setting
The purpose of this study is to identify the characteristics of patients' behavioural patterns related to declared anxiety levels in a day-care surgical unit using ethological analysis of video-recordings of the pre-operative interview with the nurse.
Read the detailed description
Guidelines in anaesthesia recommend systematic preoperative anxiety management to prevent negative perioperative impact, including impaired memory of important instructions and high incidence of post-operative acute and chronic pain. Self-administered questionnaires linked to scales to assess anxiety in the preoperative setting are usual practice. Yet, they are time consuming and rely on patient willingness to comply with instructions, which is not always reliable. The effects of acute anxiety on behaviour are poorly explored in the preoperative context. Quantifying and characterizing behavioural patterns in anxious patients using an applied ethological approach may provide useful information for reliable, accurate and objective assessment before surgery.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation between behaviour and anxiety (time frame: 1 day). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Mar 2026.
