Abstract: A secondary analysis of data from national bereavement surveys conducted in 2014, 2016, and 2018 was conducted with the aim of identifying the contribution of various patient and bereavement backgrounds to the outcomes of the Bereavement Survey. The data were evaluated in terms of structure and process of care (CES), achievement of a desirable death (GDI), complexity grief (BGQ), and depression (PHQ-9). The large data set and comprehensive analysis of bereavement survey outcomes clarified the need for adjustment of confounding variables and which variables should be adjusted for in future analyses. Overall, the contribution of the background factors examined in this study to the CES (Adj-R2=0.014) and overall satisfaction (Adj-R2=0.055) was low. The contribution of the GDI (Adj-R2=0.105) was relatively high, and that of the PHQ-9 (Max-rescaled R2=0.200) and BGQ (Max-rescaled R2=0.207) was non-negligible.
