Summary

The goal of this clinical trial is to determine whether an eye-tracking interactive agent can ameliorate communication impairments and reduce the incidence of complications among non-verbal patients in the intensive care unit (ICU). The main questions it aims to answer are:

Does the eye tracking interactive agent alleviate communication impairments among non-verbal patients in the ICU? Does the eye tracking interactive agent improve communication efficiency among non-verbal patients in the ICU? Does the eye tracking interactive agent m reduce the incidence of negative emotions among non-verbal patients in the ICU? Does the eye tracking interactive agent shorten the ICU length of stay for non-verbal patients in the ICU? Does the eye tracking interactive agent reduce the dosage of analgesic and sedative medications for non-verbal patients in the ICU? Does the eye tracking interactive agent improve family satisfaction for non-verbal patients in the ICU? Does the eye tracking interactive agent alleviate nurses' communication burden among non-verbal patients in the ICU? Researchers will compare eye tracking interactive agent to conventional techniques to see if e eye tracking interactive agent works to alleviate communication impairments.

Participants will:

Use an eye tracking interactive agent for augmentative communication for 2 consecutive days Document each communication's details, ICU LOS, and analgesic-sedative dosages; assess communication difficulty severity, delirium, anxiety, family satisfaction and nurses' communication burden with validated scales.

Conditions

  • Eye Tracking
  • ICU
  • Communication Barriers
  • Non-Verbal Communication

Interventions

DEVICE

eye-tracking interactive agent

The eye-tracking interactive agent consists of an eye-tracker, an iPad, and a floor-standing stand. Positioned at the patient's bedside, the system is activated upon the patient's eye opening, allowing the patient to vocalize via this eye-tracking interactive system.

OTHER

conventional techniques

Nurses communicate with patients through verbal inquiry, hand gestures, head nods or shakes, and simple paper-and-pencil tools; patients unable to write communicate solely via body language. Needs are guessed only when patients exhibit obvious discomfort.
