Pilot Study for Thyroid Surgery by Preoperative Video Support and Personalized and Secure Web Platform (AMEDOP)

Interest of Improving Preoperative Medical Information by Video Support and Personalized and Secure Web Platform: Pilot Study in Thyroid Surgery (AMEDOP)

The medical information delivered to the patient before any surgery constitutes an essential and compulsory step during the initial management of the operated patient.

There are different reasons for the quantity and quality of medical information retained by the patient. An internet platform with personalized and secure access has been developed. This platform contains, among other things, an explanatory video of thyroid surgery and allows the patient to have access to information on surgical management at any time.

The investigators believe that unlimited access for the duration of the study to this platform could reduce the preoperative anxiety level of patients.

Study Overview

• Status: Recruiting
• Conditions: Thyroid
• Intervention / Treatment: Other: access to the internet information platform

Detailed Description

The objective is to assess the impact of additional, personalized and accessible preoperative medical information via a secure internet platform on the anxiety level of patients before their surgery. For this, patients agreeing to participate in the study will be randomized (drawn at random) during the inclusion visit and divided into one of the following two groups:

• The control group: patients included in this group will receive the usual medical information as part of the surgery performed;
• The experimental group: the patients included in this group will have, in addition to the usual medical information, personalized and secure access to a platform so that they can have additional information on the surgery performed.

• Study Type: Interventional
• Enrollment (Estimated): 220
• Phase: Not Applicable

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Amsterdam Preoperative Anxiety and Information Scale (APAIS) SCORE	rate of patients with perioperative anxiety symptoms refind by APAIS SCORE >= 11. Rate from 1 (absent) to 5 (extrem). Score 2 to 4 : rejection of information, 5 to 7 : medium desire for information, > 7 : hungry for information.	Baseline Day [-90 / -7] and Surgery Day [-1 / 0]

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
State-Trait Anxiety Inventory (STAI-ETAT) SCORE	overall anxiety score. 20 items in the form of a 4-response Likert scale (from 1 : low anxiety to 4 : highest anxiety). The score goes from 20 to 80 depending of the degree of anxiety.	Baseline Day[ -90 / -7], Surgery Day [-1 / 0], discharge from the hospital Day [0 / 7] and postoperative visit Day [5-30]
Internet use self-questionnaire	Description of internet use and median number of internet use during the preoperative period collected using the follow-up book given to the patient during the inclusion visit. 4 items, if the answer for the 1st item is YES (Do you regulary consult the Internet for your health?) the subject must complete the item 2 and 4. If it's NO the subject must complete only the item 3. Item 2 is "why are you consulting internet" the subject had 3 possibility multiple choice questionnaire by answering with yes or no. Item 3 "Why the subject Don't use internet" 3 possibility multiple choice questionnaire by answering with yes or no. Item 4 "utility of the information found on internet" rate from 1 (none) to 5 (very important).	Baseline Day [-90 / -7]
Internet use self-questionnaire	Description of internet use and median number of internet use during the preoperative period collected using the follow-up book given to the patient during post opérative visit. 4 items, if the answer for the 1st item is YES (Do you regulary consult the Internet for your health?) the subject must complete the item 2 and 4.
