The purpose of advance care planning is to allow an individual to maintain autonomy in end-of-life medical decision-making even when incapacitated by disease or terminal illness. The intersection of EOL medical technology, ethics of EOL care, and state and federal law has driven the development of the legal framework for advance directives. However, from an ethical perspective the current legal framework is inadequate to make ADs an effective EOL planning tool. One response to this flawed AD process has been the (...) development of Physician Orders for Life Sustaining Treatment. POLST has been described as a paradigm shift to address the inadequacies of ADs. However, POLST has failed to bridge the gap between patients and their autonomous, preferred EOL care decisions. Analysis of ADs and POLST reveals that future policy should focus on a communications-based approach to ACP that emphasizes ongoing interactions between healthcare providers and patients to optimize EOL medical care to the individual patient.
