Uncertainty About Advance Care Planning Treatment Preferences Among Diverse Older Adults

Abstract

The complexities associated with advance treatment decisions may result in decisional uncertainty and poorly informed choices, particularly among vulnerable populations such as minorities and patients with limited health literacy. Using a hypothetical scenario, we assessed uncertainty about treatment preferences among 205 chronically ill, English/Spanish-speaking older adults from a county outpatient clinic in San Francisco. Participants were read a scenrio that described a very poor health state and poor outcome of life support treatment. Participants were asked to imagine that they were in this scenario and to choose either: all life support treatments; try life support with an option of stopping; or no life support. They were then asked how certain they were about this decision. Forty-five percent of participants were uncertain about their decision. In adjusted multivariate analysis, Latinos and Asian/Pacific Islanders were more likely than Whites to be uncertain about their treatment decisions, as were participants with limited versus adequate literacy and poor versus good self-rated health. Many patients may be uncertain about advance treatment preferences. Culturally sensitive, literacy-appropriate tools are needed to address decisional uncertainty and to help patients prepare for decision making about their future health care.
