Advance Directives Revisited (2002 vs 2023): Are We Closer to Uniformity?

Background And Objectives: Advance directives (ADs) are based on state-specific statutes that vary in structure, terminology, and options. This variability leads to inconsistent end-of-life (EOL) care for patients who have executed an AD in 1 state but fall ill in another state. This study revisits a 2002 article that identified considerable differences in ADs to determine whether ADs have become more uniform.

Research Design And Methods: ADs from all 50 states and the District of Columbia were examined to determine the frequency of document types and seven key issues. The results were compared to the 2002 study using nonparametric approaches. Mean numbers of key issues were compared using t-tests and 1-way analysis of variance.

Results: Consistent with 2002, 3 states in 2023 provide statutes for a healthcare power of attorney (HCPOA). However, states offering a combined HCPOA, and living will (LW), deemed an advance directive for healthcare (ADHC), increased from 13 to 30. Between both studies, Long-Term Care increased significantly in LW and ADHC, whereas Artificial Sustenance significantly increased in LW. Despite the rising prevalence of Alzheimer's in the United States, only 10% of states included this issue in 2023.

Discussion And Implications: Despite evolving healthcare trends, minimal revisions have been made to ADs since 2002. This lack of uniformity can cause confusion regarding the proper understanding of EOL wishes. The authors recommend that the Uniform Act for Advance Directives be revisited to promote greater uniformity in ADs and ensure that individuals' preferences are understood and respected across different states.
