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

This study aims to test the effects of a patient decision aid (PDA) on planning for end-of-life (EOL) care among older adults with COPD. The main questions it aims to answer are: 1. Does a PDA improve the process of a person to make decisions on EOL care? 2. Does a PDA improve the readiness of a person to join advance care planning (ACP) communication? 3. Does a person make an advance directive after using a PDA? Participants in this study will: 1. Be randomly assigned to one of two groups. 2. In the experimental group, participants will receive two 60-minute interactive consultations over four weeks, using a PDA to help clarify values and preferences for future medical care. A guidebook summarising these future care options will be provided. 3. In the control group, participants will receive two 60-minute sessions on lifestyle modification and self-care management over four weeks using a guidebook with coaching. A guidebook summarising general health information will be provided. Researchers will compare the intervention group to the control group to see if the PDA is better at improving the decision-making process on EOL care, the readiness of a person to join ACP communication and the chance to make an advance directive.
