Nonverbal Communication clinical trials

Brain Computer Interface for Communication in Ventilated Patients

Objectives: Specific Aim 1: To demonstrate the feasibility of using a Steady State Visual Evoked Potential (SSVEP) based Brain Computer Interface (BCI) device to facilitate communication of common patient needs in alert mechanically ventilated patients in the Intensive Care Unit (ICU). Specific Aim 2: To determine patient, family and bedside nurse satisfaction with communication using the BCI device and elicit open-ended feedback to guide future device improvements Design: Translational pilot study of a Steady State Visual Evoked Potential (SSVEP) based BCI system to facilitate communication in intubated patients, with sequential use of the BCI device and a picture board. Selection of the primary self-identified primary patient need on the BCI device will be compared to the icon selected on the picture board (reference standard). A patient satisfaction survey will then be provided to the patient or a family member following use for 2 hours a day for 3 consecutive days. Primary outcome: Accurate selection of the illustrative icon on the brain computer interface representing the physical or emotional need self-identified by the patient as being the most common trigger for communication with the bedside nurse during their admission. Secondary outcome: Selection by patients or family of "agree" or "strongly agree" with the statement "The Brain computer interface device allowed me to communicate my needs to the bedside nurse adequately". Intervention: Use of the brain computer device in the ICU for communication for 2 hours a day for 3 consecutive days Control/ Comparator: Sequential use of a communication picture board for 2 hours a day for 3 consecutive days, on the same days that the BCI device is used Sample Size: 30 mechanically ventilated but alert patients in the Intensive Care Unit
