Cardiac arrest & resuscitation

Large-scale automated phenotyping of cardiac arrest and withdrawal of life-sustaining therapy using electronic health record data

ResuscitationPublished Diagnostic accuracy study

Authors' conclusion

These models establish a reproducible framework for automated cohort identification. Nearly half of comatose post-arrest patients died following WLST, with 42 % of these deaths occurring within 72 h, highlighting the impact of early prognostication decisions.
