Summary

For family members of chronically critically ill (CCI) patients, an ICU admission marks a significant milestone in the patient's illness trajectory that highlights the onset of end of-life issues and an abrupt need for family members to assume the caregiver role for the first time. Assuming the caregiver role can have devastating and longstanding health consequences for family members, which can impair their ability to sustain caregiving behaviors for a CCI patient. The unrelenting psychological distress perceived by caregivers of CCI patients is linked to significant reductions in their self-management and health outcomes. The purpose of this study is to evaluate a theoretically-derived Adaptive SenSor-Based Intervention for Caregiver Self-ManagemenT (ASSIST) intervention compared to an attention control condition for first time caregivers of CCI patients discharged to an extended care facility. One group will be exposed to the ASSIST intervention and will wear the sensor-based technology for 30 days and receive a daily dose of MMT. Biophysical sensor data (blood pressure, heart-rate variability, pedometry, and actigraphy) will be continuously acquired and analyzed using anomaly detection and machine learning techniques to vary the dose intensity (number of doses per day) of the two components of ASSIST adding a real-time, adaptive feature to promote caregiver self-management. The other group will wear the sensor-based technology for 30 days but will not receive the daily dose of MMT. The investigators will randomly assign participants to each group.

Detailed description

The investigators will conduct a randomized controlled trial to examine the ASSIST intervention compared to an attention control condition among 20 first time caregivers of CCI patients discharged to an extended care facility. The investigators will collect mixed methods data at baseline (T1) on Day 15 (T2) and Day 30 (T3) after subject enrollment to describe changes in proximal and distal outcomes. We have chosen our time points to capture neural and behavioral changes associated with the intervention. The investigators aim to: 1. Determine whether there are differences in the distal outcomes \[psychological burden (anxiety, depression, caregiver burden, HRQoL), cardiovascular health (BP and HRV) and economic costs\] between subjects who were exposed to ASSIST compared to those exposed to the attention control condition. 2. Examine whether decentering, self-efficacy, decision-making, motivation, caregiver activation, and perceived stress mediate the relationship between exposure to a self-management condition (ASSIST vs. attention control) and the proximal (self-management) outcomes (stress reduction behaviors, sleep hygiene behaviors, and physical activity). 3. Determine if social support and demographics (gender and age) moderate the proximal outcomes \[emotional distress, sleep quality, and physical activity\] or distal outcomes \[psychological burden (anxiety, depression, caregiver burden, HRQoL), cardiovascular health (BP and HRV) and economic costs\]. 4. Explore the differences in brain activation (structural and fMRI scans) and HPA function and stress response (hair cortisol, inflammation panel) between subjects exposed to ASSIST compared to those exposed to the attention control condition.
