The mortality rates of patients in a German palliative care unit on working days were compared with those for weekends and public holidays. The mortality rates on weekends and public holidays were 18% higher than on working days.
Patients in some palliative care units may be at higher risk of dying on weekends and public holidays, but the exact interpretation of this correlation is unclear currently.
