State-Level Differences In Personality And Geographic Disparities In Access To Palliative Care: Findings On Openness.

57Background: There are geographic disparities in access to palliative care that cause unnecessary suffering near the end of life in low-access U.S. states. The psychological mechanisms explaining state-by-state variation in access to palliative care are poorly understood. Our objective was to examine whether state-level differences in personality explain state-by-state variation in palliative care access. Methods: We combined four datasets with state-level data for the 50 U.S. states and the national capitol.
