I-WEAR: Evaluating Wearables and Health Summaries in ICU Survivors

Summary

This pilot study investigates the use of wearable health technology and bi-weekly digital health summaries in patients recovering from intensive care. Many patients experience physical, psychological, and cognitive challenges after an ICU stay, a condition known as Post-Intensive Care Syndrome (PICS). The study aims to evaluate the feasibility and usability of wearable devices-such as smartwatches, blood pressure monitors, and smart scales-for tracking recovery in real-world settings. Participants will be randomly assigned to one of three groups: standard ICU follow-up care, wearable use only, or wearable use combined with bi-weekly health reports and optional lifestyle consultations. The study will assess participants' quality of life, experience using the technology, and adherence over a 6-month period. Results will inform the future use of digital tools in post-ICU care.
