Background: There are few studies on bereaved caregiver's perceptions of physician behavior toward death pronouncement. Although previous research indicates that most caregivers are satisfied with physician behavior toward death pronouncement at home hospices, bereaved caregiver's perceptions of death pronouncement in palliative care units (PCUs) have not been investigated. Objective: The aim was to examine bereaved caregiver's perceptions of physician behavior toward death pronouncement in PCUs.
