"We're moving to comfort care." Families hear that sentence in a hospital hallway at the worst moment of their lives, and almost no one stops to explain what it means. It means the goal has changed: instead of trying to cure an illness that can no longer be cured, the whole focus becomes keeping the person comfortable, calm, and out of pain. It is not doing nothing. It is doing everything for comfort.
It sits close to hospice and palliative care; for how those compare, see palliative care versus hospice.
