Advance care planning has gradually gained attention in recent years. Officially implemented in 2019, the Patient Right to Autonomy Act establishes Taiwan’s first formal advance directive system. Simple verbal consultations tend to encounter difficulties arising from cognitive gaps, whereas decision aids can help patients better understand information and make informed choices. Video-based decision aids provide both visual and auditory assistance with information on disease overviews, care goals, and available options. These tools are typically developed according to International Patient Decision Aid Standards. Previous studies indicate that video decision aids have been applied across diverse populations and care settings, including the general public, cancer patients, individuals with heart disease, and persons engaged in dementia care planning, reporting positive outcomes in most cases. Future research may focus on expanding the use of video decision aids to broader populations and developing innovative formats that leverage emerging technologies.
