Communication Enhancement Among Ventilated Patients in Intensive Care

A "successful" use is defined as (cumulative criteria, in chronological order):

• Activation of the device by the caregiver
• Completion of the mobility questionnaire
• Setup of the device in front of the eligible patient
• Successful calibration of the eye-tracking control
• Completion of the comprehension assessment test
• Transition to the adapted communication interface
• Use of the communication interface by the patient by clicking on the icon requested by the caregiver

This time measurement will start when the device enters the patient's room and end when the patient clicks on the requested icon. It will be timed by an independent observer.

• Failure to start the tool
• Failure of the mobility test
• Failure to set up the patient
• Failure of calibration
• Failure to complete the comprehension test
• Failure to transition to the adapted interface
• Failure of communication interface operation
• Failure during the procedure:
• Failure due to interruption caused by patient's health status at any point in the procedure, other than a comprehension test result preventing interface proposal

"Communication success" rate, meaning the patient successfully conveyed the intended message. The independent observer will evaluate the first message transmitted by the patient (immediately after responding to the caregiver's request to click on an icon), right after interaction with the care team. This criterion will be collected by asking the patient: "Did you succeed in conveying the information you wished to transmit?" The answer is binary: yes or no, and can be communicated by blinking, nodding, or hand squeeze. This evaluation will focus on the first message sent using the "JIB-Tours care" device.

The independent observer will conduct individual, recorded, semi-structured interviews with patients after they have regained speech following extubation or the ability to use a phonation valve, and before discharge from intensive care. For caregivers and relatives, the semi-structured interview will be conducted immediately after device use by the independent observer. A qualitative analysis of the interviews, especially the verbatim responses, will be performed.

After device use, the independent observer will present users with a scale of 4 emoticons ranging from a least smiling face to a very smiling face. The observer will ask each user to choose the emoticon that best represents their level of satisfaction with the device. The result will be recorded by the independent observer in the Case Report Form (CRF), scored from 1 (least smiling emoticon) to 4 (most smiling emoticon).
