The document discusses improving end-of-life care through better communication of patients' wishes. It divides the population into three groups based on health status and discusses different trajectories of chronic illnesses near death. It emphasizes that advance care planning conversations are important so treatment decisions are not made in times of crisis or grief, but rather reflect patients' values and goals. The document also discusses Physician Orders for Life-Sustaining Treatment (POLST) forms, which provide medical orders across care settings to communicate end-of-life treatment preferences. It notes POLST is voluntary but provides a consistent recognized document, and is appropriate for patients whose doctors would not be surprised if they died within a year.
