[Palliative Sedation at the End of Life: A Comparative Study of Chronic Obstructive Pulmonary Disease and Lung Cancer Patients].

Background: Although patients with chronic obstructive pulmonary disease (COPD) receive poor-quality palliative care, information about the use of palliative sedation (PS) in the last days of life is very scarce.

Objectives: To compare the use of PS in hospitalized patients who died from COPD or lung cancer and identify factors correlating with PS application.

Methods: In a retrospective observational cohort study, from 1,675 patients died at a teaching hospital between 2013 and 2015, 109 patients who died from COPD and 85 from lung cancer were compared.
