To report the effect of an early palliative care intervention on quality of life (QOL) and satisfaction with care of caregivers of patients with advanced cancer
A cluster randomization process involving patients and their caregivers in 24 Canadian medical oncology clinics supported two randomized arms: an intervention with early palliative care team referral or usual oncology care with palliative care only as needed. Further stratification of clinics by tumor site supported the two study arms. Both arms included caregivers of patients with advanced cancer, defined as having a clinical prognosis of 6–24 months and an ECOG score of 0–2, who completed previously validated instruments on care satisfaction (FAMCARE-19) and QOL (SF-36v2 Health Survey, Caregiver Quality of Life Index-Cancer [CQOL-C]). A mixed effect model evaluated intervention group improvement over the control group at baseline assessment and monthly for as many as four months.
Cluster randomized trial design
Canadian caregivers of patients with advanced cancer that receive early palliative care team intervention experience increased satisfaction with care compared to those who receive standard oncology care. Additional work to explore the impact of an early palliative care team intervention on caregiver QOL with an attention on factors like sample size and contextual factors of care will contribute to the science in this area.
Few clinical trials assess the effect of early palliative care interventions on caregivers of patients with advanced cancer. Current standards of care for patients with advanced cancer include integrating palliative care to improve patient care satisfaction and QOL. This study shows evidence that including those patient caregivers in such an approach improves their satisfaction with care, although it is unclear whether it improves their overall QOL.
