Background: Aggressive medical management of cancer patients at the end of life (EOL) is an indicator of health services quality. We evaluated the variations in EOL cancer therapy utilization and in acute care hospital deaths across different types of cancer within the setting of a regionalized cancer program.
Methods: Intravenous chemotherapy and radiotherapy use within the last 14 and 30 days of life was identified through the Alberta Cancer Registry and then verified by chart review for cancer decedents residing within 50 km of the Tom Baker Cancer Centre between 2003 and 2010. Multivariable logistic regression was used to examine variations in outcomes of interest by cancer, adjusting for age and other factors in prespecified models.
Results: Of the 9863 decedents included in the study, 3.0 and 6.3 % received chemotherapy within the final 14 and 30 days of life, respectively. In multivariable model, breast, hematological, and gynecological cancers were at least 2.5 times more likely than other cancers to undergo EOL chemotherapy. Radiotherapy was given to 4.6 % of decedents within 14 days of death, but only 66 % (359/542 courses) were completed as prescribed. Acute care admission within 14 days of death was seen in 44 % of decedents and 34 % died in the hospital.
Conclusions: In our regional cancer program, the intensity of cancer therapies near the end of life varied considerably across different cancer types. Such variations may be unwarranted. A substantial proportion of cancer deaths occurred in the acute care setting. Greater efforts to integrate palliative care in outpatient cancer services are needed.
