Can a smartphone app keep cancer patients out of the hospital?
NCT ID NCT07301996
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a mobile app that lets cancer patients report their symptoms to their doctor can reduce unplanned hospital visits. 166 adults with solid cancers on systemic therapy participated. Half used the app before clinic visits, while the other half had usual care. The goal was to see if the app helped catch problems earlier and avoid emergency visits or hospital stays.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- mobile symptom-reporting app
- What this could lead to
- If it works, this could help cancer patients avoid unplanned hospital visits by letting doctors see symptoms earlier.
- What could go wrong
- This is a small, single-center study with no blinding, so results may not apply broadly. The app requires patients to use a smartphone, which may limit who can participate.
