Why the study?
Does age ≥70 years affect the incidence of cardiac arrest, survival after CPR, and the institution of DNAR orders following cardiac surgery compared to younger patients?

Severity of illness, rather than age alone, appears to be the primary determinant of 'Do Not Resuscitate' orders following cardiac surgery.
No takes yet. Share an insight, caveat, or question.
Severity of illness, not age, primarily drives DNAR orders after cardiac surgery; leaves open whether age independently affects CPR survival.
Mackay et al. (2004) studied this question.
