Trends in Engagement in Advance Care Planning Behaviors and the Role of Socioeconomic Status.

We investigated the trends in advance care planning (ACP) between 2002 and 2010 and whether socioeconomic status explained such trends. We conducted a pooled regression analysis of Health and Retirement Study data from 6052 proxies of deceased individuals. We studied 3 ACP behaviors, discussing end-of-life (EOL) care preferences, providing written EOL care instructions, and appointing a durable power of attorney for health care (DPAHC). ACP increased by 12% to 23% every 2 years from 2002 to 2010. Higher household income increased the odds of having a DPAHC. Education was not associated with ACP. Socioeconomic status alone appears to play a very limited role in predicting ACP. Engagement in ACP likely depends on a constellation of many social and contextual factors.
