End-of-life cancer care: Health service delivery in the last 12 months of life in Calgary, Alberta, Canada.

Abstract

171 Background: In Calgary, Alberta, the Calgary Zone Palliative Care Collaborative (CZPCC) undertook a study to examine the current state of cancer and palliative services and to recommend steps to address gaps in service delivery. We hypothesized that early access to palliative care services would reduce utilization of active cancer treatments and services for individuals nearing the end of life. Our study objectives were to determine the utilization and timing of acute, palliative and oncology-related services in Calgary. Methods: This retrospective study examined cancer registry and administrative data for patients > 18 years, who died in 2012. Measures of aggressive end of life care (EOL) were also collected. A combination of descriptive statistics, tests of association and multivariate regression analysis were conducted. Results: N = 1909 died of cancer in 2012: median age 73 years (IQR: 62-82 years) and median disease duration 364 days (IQR: 92-1114 days). 40.6% of patients received systemic treatment in last 12 months of life. 29.9% received radiotherapy and 13.0% received psychosocial/spiritual care. Palliative care contact was 80.7%, inclusive of 20.6% who had an intensive palliative care unit admission. 5.2% had EOL chemotherapy and 3.8% received EOL radiotherapy. Up to 10.4% of patients had one or more hospital admission. There was no significant effect of age on those who received aggressive EOL care. Men had an increased probability to receive aggressive EOL care (p = 0.015). Tumor group was also associated with receiving aggressive EOL (p < 0.001), with the highest utilization in Head and Neck and hematological malignancies. In patients with a disease duration of > 4 months those who received palliative care at least 2-3 months prior to death were less likely to receive aggressive EOL care (P < 0.001). Patients whose disease duration was < 1 month were less likely to receive aggressive EOL care if they received palliative care services (p = 0.02). Conclusions: The provision of palliative care services at the end of life is most needed among men and certain tumor groups who are the highest users of aggressive EOL care.
