NCT04582149

Brief Summary

The purpose of this study is to evaluate the feasibility of use of a wearable communication device for critically ill patients who are admitted to the intensive care unit (ICU) and mechanically ventilated. The study will assess the safety, tolerability, and ease of use of the EyeControl device, and examine its potential monitoring capabilities.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants Who Succeeded in Operating the EyeControl Device

    Successful operation of the device was defined as completing a set of assignments termed as a proficiency test. This proficiency test included the ability to call for help and the ability to choose a correct answer out of multiple choice questions that were read to the patient using the device. Participants were able to try to learn to operate the device once per day for up to three days.

    Up to Day 3

  • Time To Successful Operation of the EyeControl Device

    Successful operation of the device was defined as completing a set of assignments termed as a proficiency test. This proficiency test included the ability to call for help and the ability to choose a correct answer out of multiple choice questions that were read to the patient using the device. Participants were able to try to learn to operate the device once per day for up to three days. The time (in minutes) of training required for a patient to successfully operate the device was documented.

    Up to Day 3

  • Number of Participants Successfully Operating the EyeControl Device Per Attempt Day

    Successful operation of the device was defined as completing a set of assignments termed as a proficiency test. This proficiency test included the ability to call for help and the ability to choose a correct answer out of multiple choice questions that were read to the patient using the device. Participants were able to try to learn to operate the device once per day for up to three days. The study day when participants passed the proficiency test was documented.

Study Arms (1)

EyeControl Eye-tracking Device

EXPERIMENTAL

Ventilated ICU patients using the EyeControl wearable, eye-tracking device.

Device: EyeControl Eye-tracking Device

Interventions

The EyeControl is a new, wearable, eye-tracking device that facilitates communication by means of internal feedback to the patients with a bone-conducting speaker. In this way, the device can ask the patient what he or she wants to say, and the patient replies by eye gestures such as blinking or moving the eyes in a certain direction. Once the patient is able to operate the device, it will stay on the patient for as long as she or he would like it on, or until the patient is successfully extubated or discharged from the ICU, whichever is earliest.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Intensive Care Unit (ICU) Admission
  • Mechanically ventilated for at least 24 hours
  • Richmond Agitation Sedation Score (RASS) between -1 to 1 at the time of screening
  • Ability to follow simple commands

You may not qualify if:

  • Inability to follow commands during screening (at a minimum: open and close eyes, move eyes to one side or the other)
  • Known cerebral injury (acute or chronic) in the dominant hemisphere concerning for aphasia on clinical assessment
  • Significant pre-existing neurologic (i.e., dementia and/or cognitive deficiencies), psychiatric, or baseline communication challenges that would confound outcomes assessments
  • Inability to blink or move eyes for any reason
  • Prisoner or incarceration
  • Inability or unwillingness to provide informed consent
  • Unwillingness to be contacted for follow-up
