Summary

This study tested a social robot named ARI in a day hospital for elderly patients. The robot welcomed people, reminded them about hygiene, and helped them prepare for medical visits. Researchers asked 115 participants—patients, family caregivers, and nurses—how acceptable and easy to use the robot was. The goal was to see if robots can support care workers and improve the hospital experience.

What this could mean

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

Active substance
socially assistive robot (ARI)
What this could lead to
If successful, this could show that robots can help guide, inform, and entertain elderly patients in hospitals, potentially easing staff workload.
What could go wrong
This is a small, completed study focused on user opinions, not health outcomes. The robot may not work well in all hospital settings or with all patients.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The population includes the 3 categories of actors attending the day care hospital: patients, their carers (family or close carers) and professionals. The investigators will consider all the actors who are likely to interact with the ARI social robot, including people who are not formally part of the patients' care pathway, but whose presence is important to their care. The individuals included will have various profiles, from a demographic, sociological and clinical point of view. The patients and their carers mainly live in the Paris region. Patients mainly consult the day care hospital for memory problems, but are likely to display associated cognitive, behavioural or physical problems.

Ages

18 years and older
