Continuous deep sedation does not appear to shorten life in patients with advanced cancer cared for by specialized palliative care services, and could be considered a viable option for palliative care in this setting, a new study published online ahead of print in the journal The Lancet Oncology has shown.1

Because continuous deep sedation before death as a form of palliative sedation therapy has become a contentious topic, particularly in regard to whether it shortens survival, researchers sought to evaluate whether continuous deep sedation shorten patient survival.

For the study, researchers analyzed data from a large multicenter prospective cohort study that enrolled 2426 patients from 58 palliative care institutions across Japan. For this analysis, 1827 of the 2426 patients were included. Of those, 15% received continuous deep sedation.

Results showed that median survival was 22 days (95% CI: 21-24) in the continuous deep sedation group and 26 days (95% CI: 24-27) in the no continuous deep sedation group (HR, 1.01; 95% CI: 0.87-1.17; P=.91).

Researchers found that care setting had a significant effect on the association between sedation and survival (P=.021), while age, sex, performance status, and volume of artificial hydration had no impact.
