Effect of Using a Reminder to Encourage Patients to be Active During Their Hospital Stay : a Multicenter Randomised Controlled Double Blind Study.

Not applicable Interventional Groupe Hospitalier du Havre · NCT07492745

What this trial studies

This interventional study compares a vibrating reminder device given to inpatients with usual care to encourage daily walking and simple strengthening exercises. Eligible patients are adults aged 50+ with a Clinical Frailty Scale score of 4 or higher who can get up from a chair and communicate with staff. Participants will receive the vibrating reminder during their admission and outcomes will focus on physical activity, functional capacity, and independence at discharge and in the early post-discharge period. The device is intended as a low-cost, easy-to-implement way to increase mobility without adding staff.

Who should consider this trial

Good fit: Ideal candidates are inpatients aged 50 or older with a Clinical Frailty Scale ≥4 who can stand up unaided, communicate and consent, and are expected to stay at least five days without contraindications to activity.

Not a fit: Patients unlikely to benefit include those with short expected stays (<5 days), medical contraindications to activity, terminal illness, scheduled surgery, pregnant women, or those who cannot understand French.

Why it matters

Potential benefit: If successful, the reminder could reduce in-hospital functional decline, preserve muscle strength, and help patients leave the hospital more independent.

How similar studies have performed: Walking interventions of about 25–40 minutes daily have shown benefits in meta-analyses and reminder systems improve adherence in other settings, but using a vibrating watch to prevent hospital-associated functional decline is a relatively simple and emerging approach.
