ABSTRACT
INTRODUCTION: Communication with ventilated patients in the Intensive care unit (ICU) is challenging. This may lead to anxiety and frustration, potentially contributing to the development of delirium. Various technologies, such as eye-tracking devices, have been employed to facilitate communication with varying grades of success. The EyeControl-Med device is a novel technology that delivers audio content and allows patients to interact by eye movements and could potentially allow for better communication in this setting. METHOD(S): A single-arm pilot study of patients in a mixed ICU. Patients underwent at least 3 sessions with the EyeControl-Med device administered by a speech-language pathologist. Communication and consciousness were assessed using the Lowenstein communication scale (LCS) and delirium was assessed by a computerized version of the CAM-ICU during the first and last device usage sessions. RESULT(S): 15 patients were included, 40% of whom were diagnosed with COVID-19. All patients completed three to seven usage sessions. The mean LCS score improved by 19.3 points (p < 0.0001), with each of its five components showing significant improvements as well. The mean number of errors on the CAM-ICU tool decreased from 6.5 to 2.5 (p=0.0006), indicating lower rates of delirium. No adverse effects were observed. CONCLUSION(S): The EyeControl-Med device may help enhance communication and re-orientation in this patient population while reducing the helplessness and anxiety associated with lack of communication. It may reduce the manifestations and duration of delirium in ventilated critically ill patients. Controlled studies are required to establish this effect.
