Little is known about how patients with incurable cancer and caregivers differ in their prognostic awareness, and the relationship between caregiver prognostic awareness and their psychological distress.
Objective:
To investigate prognostic awareness in caregivers of patients with incurable cancer and prognostic discordance in patient–caregiver dyads and its association with psychological distress.
Design:
This is a cross-sectional study.
Setting/Subjects:
In total, subjects were 390 caregivers of adults with incurable lung, gastrointestinal, and brain cancers at a cancer center in the northeastern United States.
Measurements:
The Prognosis and Treatment Perceptions Questionnaire was used to assess prognostic awareness and Hospital Anxiety and Depression Scale to assess psychological distress.
Results:
In total, 39.7% (n = 147/370) and 17.3% (n = 64/370) caregivers reported clinically significant anxiety and depression symptoms. And 53.7% of caregivers reported the patients' cancer as “curable” and 44.1% reported the cancer was “not terminal.” Caregivers' report of curability was not associated with their anxiety (odds ratio [OR] = 0.99, p = 0.93) or depression (OR = 1.05, p = 0.32) symptoms. Among 42.5% (124/292) and 26.0% (76/292) of dyads (n = 292), both patients and their caregivers agreed in their perception of the cancer as curable and incurable, respectively. In 19.9% of dyads (n = 58), patients reported their cancer as curable, while their caregivers reported it as incurable. In 11.6% of dyads (n = 34), patients reported the cancer as incurable while caregivers reported it as curable.
Conclusions:
More than half of caregivers have misperceptions about the patients' likelihood of cure, and one-third of patient–caregiver dyads have discordant perceptions. Supportive care interventions may facilitate conversations and enhance prognostic understanding in patients with incurable cancer and their caregivers.
