Background: The aims of this study were to (i) conceptualize dimensions of a good death in Japanese cancer care, (ii) clarify the relative importance of each component of a good death and (iii) explore factors related to an individual's perception of the domains of a good death. Methods: The general population was sampled using a stratified random sampling method (n = 2548; response rate, 51%) and bereaved families from 12 certified palliative care units were surveyed as well (n = 513; 70%). We asked the subjects about the relative importance of 57 components of a good death. Results: Explanatory factor analysis demonstrated 18 domains contributing to a good death. Ten domains were classified as ‘consistently important domains’, including ‘physical and psychological comfort’, ‘dying in a favorite place’, ‘good relationship with medical staff’, ‘maintaining hope and pleasure’, ‘not being a burden to others’, ‘good relationship with family’, ‘physical and cognitive control’, ‘environmental comfort’, ‘being respected as an individual’ and ‘life completion’. Conclusions: We quantitatively identified 18 important domains that contribute to a good death in Japanese cancer care. The next step of our work should be to conduct a national survey to identify what is required to achieve a good death.

Purpose: To explore the associations between place of death and quality of death and dying and caregiver burden in terminally ill patients with cancer and their families. Methods: Two bereavement surveys were conducted in October 2008 and October 2011. A total of 2,247 family caregivers of patients with cancer who were deceased responded to the mail surveys (response rate, 67%). Family members reported patient quality of death and dying and caregiver burden by using the Good Death Inventory and Caregiving Consequences Inventory. Results: Patient quality of death and dying was significantly higher at home relative to other places of dying after adjustment for patient and/or family characteristics (adjusted means): 5.0 (95% CI, 4.9 to 5.2) for home, 4.6 (95% CI, 4.5 to 4.7) for palliative care units, and 4.3 (95% CI, 4.2 to 4.4) for hospitals. For all combinations, pairwise P < .001; the size of the difference between home and hospital was moderate (Hedges' g, 0.45). Home was superior to palliative care units or hospitals with respect to “dying in a favorite place,” “good relationships with medical staff,” “good relationships with family,” and “maintaining hope and pleasure” (P < .001 for all combinations of home v palliative care units and home v hospitals). Home death was significantly associated with a lower overall (P = .03) and financial caregiver burden (P = .004) relative to hospital death. Conclusion: Dying at home may contribute to achieving good death in terminally ill patients with cancer without causing remarkably increased caregiver burden. Place of death should be regarded as an essential goal in end-of-life care.

Complicated grief, which is often under-recognized and under-treated, can lead to substantial impairment in functioning. The Brief Grief Questionnaire (BGQ) is a 5-item self-report or interview instrument for screening complicated grief. Although investigations with help-seeking samples suggest that the BGQ is valid and reliable, it has not been validated in a broader population. A questionnaire was mailed to a randomly selected sample (n = 5000) residing in one of 4 areas of Japan. The BCQ was examined for responders who were bereaved more than 6 months and less than 10 years (n = 915). Non-specific psychological distress was assessed with the K6 screening scale. Multiple group confirmatory factor analysis supported a uni-dimensional factor structure and the invariance of parameters across gender and age. Cronbach's alpha was sufficiently high (alpha = .75) to confirm internal consistency. Average Variance Extracted (0.39) was higher than the shared covariance (0.14) between BGQ and K6, suggesting discriminant validity. The results of this study support the reliability and validity of the BGQ in the Japanese population. Future studies should examine predictive validity by using structured interviews or more detailed scales for complicated grief.
