Wearables and digital health summaries to support ICU survivors' recovery
Official title: I-WEAR: From ICU to Recovery - Evaluating the Feasibility and Usability of Bi-Weekly Health Summaries Using Wearables in Patients After Intensive Care Unit Treatment - A Pilot Study
Run by Ludwig Boltzmann Gesellschaft · NCT07035106 · Data updated 2026-11-12
This pilot will test whether wearable devices plus optional twice-monthly digital health summaries help adults 18–65 recover after an ICU stay, focusing on people with diabetes or coronary artery disease.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are ICU survivors aged 18–65 who had an ICU stay of at least 48 hours, have diabetes and/or coronary artery disease, live in Austria, and have a smartphone and home internet.
✕Probably not a fit
Patients without smartphone or internet access, those living outside Austria, those without the specified comorbidities, or those with implanted pacemakers/defibrillators are unlikely to benefit from participation.

What this trial studies
This single-center, randomized feasibility pilot in Vienna will enroll 60 ICU survivors and assign them to standard follow-up, wearables only, or wearables plus bi-weekly health summaries and optional lifestyle consultations. Participants use a smartwatch, smart scale, and blood pressure monitor with data aggregated via a secure cloud app, and they are followed for six months. Primary outcomes are feasibility (recruitment, retention, device adherence) and usability (System Usability Scale and interviews), with secondary outcomes including health-related quality of life. Results will inform whether larger trials of remote monitoring and digital summaries are worthwhile for post-ICU care.
Why it matters
Potential benefit: If successful, this approach could enable earlier detection of recovery problems and more personalized follow-up, potentially improving quality of life after ICU discharge.
How similar studies have gone: Remote monitoring and wearable-based programs have shown promise in chronic cardiac and diabetes care, but using wearables specifically for post-ICU recovery is relatively novel with limited prior trial data.
