Summary

This study explores whether a wrist-worn sensor can identify early signs of delirium in hospitalized adults aged 65 and older. Delirium is a common and serious complication of hospitalization, and early detection is key. Participants wear a consumer-grade sensor on their wrist to track sleep, heart rate, breathing, and movement. Researchers will look for patterns that might signal the onset of delirium, potentially enabling faster intervention.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Wearable wrist sensor (consumer-grade accelerometer) to monitor vital signs and movement patterns
What this could lead to: If patterns are found, this could lead to a simple, non-invasive tool for early delirium detection in hospitals, potentially improving patient outcomes.
What could go wrong: This is a small exploratory study, so findings may not be conclusive or generalizable. Sensor data may not reliably distinguish delirium from other conditions.
