Context: Posttraumatic stress disorder (PTSD) may emerge or re-emerge at end of life (EOL), increasing patient suffering. Understanding factors associated with PTSD at EOL may assist clinicians in identifying high risk veterans.
Objectives: To determine rates of and variables associated with PTSD-related distress at EOL.
Methods: Retrospective observational cohort study including veterans who died within a Veterans Affairs (VA) inpatient setting between October 1, 2009 and September 30, 2018 whose next-of-kin completed the Bereaved Family Survey (BFS; N = 42,474). Our primary outcome was PTSD-related distress at EOL, as reported by veteran decedents' next-of-kin on the BFS. Predictors of interest included combat exposure, demographic variables, medical and psychiatric comorbidity, primary serious illness, and palliative care support.
Results: Veteran decedents were majority male (97.7%), non-Hispanic white (77.2%), 65 years or older (80.5%), without combat exposure (80.1%). Almost one in ten (8.9%) veteran decedents experienced PTSD-related distress at EOL. In adjusted analyses, combat exposure, younger age, male sex, and non-white race were associated with PTSD-related distress at EOL. High overall medical comorbidity, dementia, and psychiatric comorbidities including both substance use disorder and depression, were also associated with PTSD-related distress at EOL. Palliative care consultation and emotional support were associated with decreased odds of PTSD-related distress, while pain was associated with increased odds of PTSD-related distress at EOL.
Conclusion: Trauma and PTSD screening, pain management, and providing palliative care and emotional support at EOL, particularly in at-risk groups such as veterans from racial/ethnic minority backgrounds and those with dementia, are critical to decreasing PTSD-related distress at EOL.
