Using Technology to Measure Delirium Severity in ICU Patients Over 50

What this Trial Is About

Researchers are studying delirium severity in patients over 50 years old who are admitted to the Intensive Care Unit ICU. This observational study aims to develop a passive digital marker PDM using video recordings and a trained convolutional neural network to measure delirium severity. The study also evaluates how well this digital marker compares to traditional delirium severity tools and examines its acceptance and usability by ICU nurses, patients, and caregivers. During the study, bedside cameras will record patients continuously for at least 72 hours while in the ICU, with possible extension if delirium persists and consent is given. Study staff will visit patients four times daily to ask questions about their mental, emotional health, mood, memory, and to assess alertness through voice and gentle physical prompts. Patients will also be asked to perform simple activities such as remembering and repeating words, shaking hands, and drawing objects or clocks. If a patients alertness is lowered, observational assessments will be performed without interfering with clinical care. Participants will be monitored until discharge from the ICU. Privacy is protected by allowing coverage of cameras and blurring faces of family, clinicians, and sensitive areas before analysis. Researchers will measure delirium severity, as well as the acceptability and usability of the passive digital marker over periods ranging from 12 to 60 months. Participation is voluntary and involves detailed assessments and continuous video monitoring during ICU stay.
