Wearable Sensors for Delirium Detection at an Early Stage (WeSen_delirium) - an Exploratory Study

Observational University of Zurich · NCT05677646

This study is testing if wearable sensors like the Fitbit Charge 5 can help doctors spot early signs of delirium in hospitalized adults aged 65 and older by tracking their activity and sleep patterns.

What this trial studies

This observational study aims to identify activity and sleep patterns using wearable sensors, specifically the Fitbit Charge 5, to predict the onset of delirium in hospitalized adults aged 65 and older. By analyzing sensor data, the study seeks to establish indicators that may signal the early stages of delirium, allowing for timely intervention. The research will compare patterns of activity and sleep before and after delirium episodes, as well as between individuals, to develop a predictive algorithm. The feasibility of utilizing such data for clinical research purposes will also be assessed.

Who should consider this trial

Good fit: Ideal candidates for this study are hospitalized adults aged 65 years or older who can understand and consent to participate.

Not a fit: Patients currently experiencing acute delirium or those with a recent delirium diagnosis may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection and management of delirium, improving patient outcomes and reducing hospital stays.

How similar studies have performed: While the use of wearable sensors for health monitoring is gaining traction, this specific approach to delirium detection is relatively novel and has not been extensively tested in prior studies.
