Decision Support on End-of-life Care Planning in Older Adults

Participants in this group will receive two 60-minute intervention sessions in one month. The COPD PDA consists of three main parts: The first component, clinical counselling, guides the participants in reviewing the common EOL scenarios. The second component, an evidence-based decision aid, is presented as an option grid in a booklet and a video to provide information about outcome probabilities of various treatment options and survival estimates in a balanced and unbiased manner. The information is presented in plain language for laypersons. The third component, decision coaching, introduces the concept of ACP and guides deliberation through value clarification.

The participants in the control group will receive two 60-minute health coaching sessions developed by the PI for another project as an attention placebo control. Trained research personnel will use the same amount of interaction time and similar formats to avoid threats to the study's internal validity. This intervention will focus on lifestyle modification and self-care management unrelated to the tested intervention content or outcomes. The trained research personnel will give the guidebook consisting of general self-management advice to participants in this group.
