ICU sedation, delirium & recovery
Posttraumatic Stress Symptom Trajectories in Family Caregivers of Patients With Acute Cardiorespiratory Failure
Authors' conclusion
In this study, 3 distinct PTSS trajectories among ICU family caregivers were observed, with 16% of caregivers experiencing chronic PTSSs over the subsequent 6 months.
Study context
- Population
- Family caregivers of adult medical intensive care unit (ICU) patients with acute cardiorespiratory failure (vasopressors for shock, HFNC, noninvasive positive pressure ventilation or invasive mechanical ventilation)
- Participants
- 95 family caregivers
- Exposure
- PTSS trajectories: persistently low vs resolving vs chronic
- Persistently lown = 51reference
- Resolvingn = 29
- Chronicn = 15
- Outcome
- PTSS trajectories (Impact of Events Scale-Revised within 48 hours of ICU admission, after ICU discharge, and at 3 and 6 months)
- Follow-up
- 6 months

Mean
| Outcome | Persistently low | Resolving | Chronic | P value |
|---|---|---|---|---|
| Caregiver health-related quality of life (total 36-item Short Form Survey score) · 6 monthsChronic vs Persistently low · across the 3 trajectories | 104.7 (SD 11.3) | 101.7 (SD 10.4) | 84.0 (SD 14.4) | P < 0.001 |
| Caregiver perceived effectiveness at work score · 6 monthsChronic vs Persistently low · across the 3 trajectories | 86.0 (SD 24.2) | 59.1 (SD 32.7) | 72.3 (SD 18.4) | P = 0.009 |
Characteristics at ICU admission associated with chronic trajectory
- Low caregiver resilience, prior caregiver trauma, high patient severity of illness and good patient premorbid functional status associated with the chronic trajectory
