Palliative Care Patients' Quality of Dying and Circumstances of Death-Comparison of Informal Caregivers' and Health-Care Professionals' Estimates.

The findings appear to show a high satisfaction with quality of dying and death as rated by ICGs and HCPs, but we suspect this might be indicative of a methodological challenge, that is, a ceiling effect in both assessments. Single low scoring items may provide important clues for improvement in end-of-life care. Although descriptive data show comparable mean values and standard deviations, the actual congruence of ratings is low. In summary, replacing one rating by another cannot be recommended.
