Background: As the "do not resuscitate" (DNR) discussion involves communication, this study explored (1) the effects of a title that included "allow natural death", and of information contents and outcomes of the decision; and (2) the information needs and consideration of the DNR decision, and benefits and barriers of the DNR discussion.
Methods: Healthy adults (n = 524) were presented with a scenario with different titles, information contents, and outcomes, and they rated the probability of a DNR decision. A questionnaire including information needs, consideration of the decision, and benefits and barriers of DNR discussion was also used.
Results: There was a significantly higher probability of signing the DNR order when the title included "allow natural death" (t = - 4.51, p < 0.001), when comprehensive information was provided (F = 60.64, p < 0.001), and when there were worse outcomes (F = 292.16, p < 0.001). Common information needs included remaining life period and the prognosis. Common barriers were the families' worries and uncertainty about future physical changes.
Conclusion: The title, information contents, and outcomes may influence the DNR decisions. Health-care providers should address the concept of natural death, provide comprehensive information, and help patients and families to overcome the barriers.
