Fitbits and iPhones used to predict hospitalizations in cancer patients
NCT ID NCT06587100
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 2 times
Summary
This study is testing whether wearable activity trackers like Fitbits and iPhones can help predict when cancer patients undergoing radiation therapy might need emergency care or hospitalization. Researchers will collect step counts and other health data from 260 participants to build a model that spots early warning signs. The goal is to see if this approach can keep patients safer and reduce unplanned hospital visits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Fitbit wearable activity tracker and Apple HealthKit-based devices
- What this could lead to
- If successful, this could lead to a tool that alerts doctors when a cancer patient's activity drops, helping prevent emergency visits or hospitalizations during radiation therapy.
- What could go wrong
- This is an early-stage study with only 260 participants, so the model may not work for everyone. It is designed to predict risk, not to treat or cure cancer.
