How a person's final days are managed determines whether they die with symptoms controlled and dignity intact, and it shapes the bereavement of everyone who watched. The clinical stakes are concrete: unrelieved pain, breathlessness, agitation, and noisy secretions are common, are frightening to witness, and are almost always treatable.
