Background: To compare end-of-life (EOL) care intensity across multiple cancer sites and its impact on the cost of care during the last 30-days of life. Methods: Cross-sectional retrospective study using Surveillance, Epidemiology, and End Results Program (SEER)-Medicare linked database from 2008-2013. Utilization of the following in the EOL period (last 30 days of life prior to death) was examined: 2 or more visits to the Emergency Department (ED), hospitalizations, receipt of any life-extending procedures, admission to intensive care unit, any hospice use, hospice used ≤3 days, death in hospital, or receipt of chemotherapy (last 14 days). We tallied the claims made during the EOL period for each patient. Median expenditures during the EOL period were tabulated by cancer site and stratified by receipt of hospice care. Results: EOL care utilization varied widely between cancer sites. The rates of any hospice utilization were the highest for breast cancer (48.2%) compared to ovarian (17.4%) (p < 0.001). Chemotherapy during the last two weeks of life was the highest for ovarian cancer (1.7%) and the lowest for colorectal cancer (0.5%). The median cost of care during the EOL period for patients who received hospice care was $7,547.84 (Interquartile range [IQR] $5,422-$17,293) compared to $17,179 (IQR $10,323 - $30,824) for those never received hospice care (p < .0001). There was no significant variation in median cost by cancer site for those who received hospice services (range $7,317 - $9,816). However, the cost of care varied for those who did not receive hospice care. Median costs for this subgroup was the lowest for pancreatic cancer ($14,635) and the highest for colorectal cancer ($24,324) (p < 0.001). Conclusions: Despite increasing acceptance of palliative care services and hospice in cancer care, there continues to be intensive and costly care administered during the EOL period. These costs vary considerably across cancer sites when patients do not receive hospice care, but costs are relatively similar when patient are enrolled in hospice Further research to investigate the causes of this variation should be undertaken to design interventions aimed at improving timely hospice enrollment at the EOL and reducing costly care in the EOL period.
