On the one hand, Scott Halpern and colleagues argue that "although POLST may help prevent terminally ill patients from being resuscitated or hospitalized against their will, expanding POLST beyond this narrow goal should not be advocated until POLST is clearly supported by higher levels of evidence."
On the other hand, Susan Tolle and colleagues argue that "given almost 20 years of research on thousands of patients . . . the documented benefits of the POLST paradigm support its nationwide implementation while researchers continue to evaluate the quality of POLST decisions and assess its effects on care outcomes."
