Post Intensive Care Accelerometery to Study and Support Recovery Outcomes

Summary

The primary purpose of this study is to find out whether a wrist-worn activity monitor can help healthcare professionals understand how people recover after they leave the intensive care unit (ICU), where they were cared for when they were most unwell. By tracking recovery at home, the device may help identify problems early so that the right support can be provided. The study involves adults who are discharged from the ICU in three hospitals in Edinburgh. The main questions it aims to answer are: * Can movement data from a wearable device give useful information about how people feel and function after they return home following ICU and then hospital discharge? * Do changes in activity levels relate to changes in symptoms like pain, anxiety or behavioural measures like daily functioning, sleep and cognition? There is no comparison group in this study. Participants will: * Wear a wrist-worn activity monitor * Answer a short set of health-related questionnaires

Eligibility

Inclusion Criteria:

* Adults aged 18 years or older
* Mechanical ventilation for more than 3 days
* Total ICU length of stay greater than 7 days
* Classified as "High Risk" using a validated High-Risk Tool\*
* Expected to be discharged from hospital within the next several days

Exclusion Criteria:

* Primary neurological diagnosis as the reason for ICU admission
* Identified by the clinical team as being on the palliative care pathway
* Physical activity primarily limited by the acute injury (e.g., major trauma or limb amputation)
* Unable to mobilise independently prior to the index hospitalisation requiring ICU admission due to a long-term condition and/or disability
* Lack of capacity or inability to provide informed consent

  * The High-Risk Tool (Walsh et al., 2022) assesses eight domains: recent hospital admissions; multimorbidity (≥4 chronic conditions); polypharmacy (≥4 regular medications); prior mental health disorder; substance misuse history; current antidepressant or antipsychotic therapy; need for assistance with activities of daily living (ADLs); and living alone or fragile social circumstances. Patients meeting ≥3 domains are classified as high risk for post-ICU deterioration and readmission.
