Women are more likely than men to establish "do not attempt resuscitation" (DNAR) orders after in-hospital cardiac arrest, with higher rates occurring within the first 12 and 72 hours post-resuscitation.
Despite this higher utilization of DNAR among women, there is no significant difference in survival to hospital discharge between men and women after resuscitation.
The findings suggest that while sex differences exist in the timing and frequency of DNAR orders, these do not translate into differences in survival outcomes after cardiac arrest.
