What this research studies

You would have a TrueLoo® replacement toilet seat that connects to the internet and images your urine and stool each time you use the toilet. The device analyzes those images to look for changes that can signal issues like infection, bleeding, dehydration, or constipation and flags concerning sessions for expert review. The project runs a two-arm randomized trial in assisted living or skilled nursing settings comparing usual care to care with the TrueLoo installed. Data collection is passive—most monitoring happens automatically when you use the toilet, aiming to capture events staff often miss.

Who could benefit from this research

Good fit: Ideal candidates are adults aged 65 and older who live in participating assisted living or skilled nursing facilities and use a standard toilet where the TrueLoo seat can be installed.

Not a fit: People who live outside participating facilities, use diapers or ostomy bags, have nonstandard toilets, or decline passive imaging are unlikely to benefit from this project.

Why it matters

Potential benefit: If successful, the device could help catch urinary, gastrointestinal, or hydration problems earlier so they can be treated before complications develop.

How similar studies have performed: A Phase I SBIR showed feasibility and acceptability of deploying TrueLoo in care facilities, but larger randomized trials to show clinical benefit have not yet been completed.
