Advance Directives (ADs) have traditionally focused on documenting patients' end-of-life (EOL) care preferences. Recently, discussions surrounding post-mortem care as an additional aspect of EOL care planning have gained attention. This study examined ADs across all 50 states and the District of Columbia (referred to as "entities"), assessing their inclusion of two post-mortem categories: funeral planning and anatomical gifts. Results revealed that 29% of entities offered options from both categories, 43% provided options from only one of the categories, and 27% lacked options from either category. Unexpectedly, only one entity (2%) provided all post-mortem options from both categories. These findings suggest a lack of consistency in the availability of post-mortem options across ADs. By emphasizing the importance of comprehensive EOL care planning, this study provides valuable insights into the necessity for AD standardization, particularly regarding post-mortem preferences for patients who choose to express them.
