After-death surveys are an important source of information about the quality of end-of-life care, but response rates generally are low. Our goal was to understand the potential for nonresponse bias in survey studies of family members after a patient's death in the hospital ICU by identifying differences in patient demographics and delivery of palliative care between patients whose families respond to a survey about end-of-life care and those whose families do not.
