Caregivers influence preferred place of death for patients with an advanced cancer.

Objectives: Family caregivers influence realization of home death among advanced cancer patients. However, little is known about the caregiver factors influencing patients' preferred and actual place of death. We aimed to assess caregiver factors associated with both caregivers' and patients' preferred place of death, and the association between their preferred and actual place of death.

Methods: From a prospective cohort of 600 patients with stage IV solid malignancy, and 311 caregivers, we analyzed data for 227 patient-caregiver dyads of deceased patients who responded to the question on preferred place of death for patients at least once within the last 3 years before death. We assessed the association of patients' and caregivers' preferred place of death for patients with caregivers' competency, employment, relationship quality with the patient, their relationship with the patient, family support, and the presence of a domestic helper. We controlled for relevant patient factors and utilized the actor-partner interdependence framework for analysis.

Results: Overall, 67% patients and 74% caregivers preferred a home death for patients during the last 3 years prior to patient's death. Patients whose caregivers reported greater caregiving competency were more likely to prefer a home death (average marginal effect: 0.02; 95% confidence interval, 0.003-0.04). Spousal caregivers were less likely to prefer a home death (-0.10 (-0.19, -0.004)). Caregivers lacking family support were more likely to prefer an institutional death (0.04 (0.002-0.08)). While caregivers' preferences had a marginally significant association with patients' actual place of death (p-value < 0.10), we did not find any association between patients' preferred and actual place of death.

Significance of results: Caregivers play a crucial role in shaping patients' preferred and actual place of death. Supporting caregivers, particularly spousal caregivers, and enhancing their caregiving competency could potentially help achieve a home death for the patient.
