Alexia M. Torke,Greg A. Sachs,Paul R. Helft,Sandra Petronio,Christianna Purnell,Siu Hui,Christopher M. Callahan +6 more
TL;DR: To examine the frequency of surrogate decisions for in‐hospital do‐not‐resuscitate (DNR) orders and the timing of DNR order entry for surrogate decisions, a large number of patients with DNR problems are receiving surrogate decisions.

Alexia M. Torke,Alexia M. Torke,Sandra Petronio,Greg A. Sachs,Greg A. Sachs,Paul R. Helft,Christianna Purnell +6 more
TL;DR: A conceptual model of the role of communication in decision making is built, based on literature from medicine, communication studies and medical ethics, and there is evidence of high surrogate distress associated with decision making that may be alleviated by communication-focused interventions.
