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.
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.
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.
