Abstract 15948: Frequency and Prognosis of Recurrent In-hospital Cardiac Arrest

Introduction: Nearly 200,000 patients experience an in-hospital cardiac arrest (IHCA) annually in the U.S. However, the proportion of patients who experience a recurrent IHCA and the associated prognosis with a recurrent cardiac arrest is unknown. Methods: Within Get With The Guidelines-Resuscitation, we identified 192,250 patients with an IHCA between 2000 to 2014. Patients were categorized as having no recurrent IHCA (only 1 event), a recurrent IHCA (2 or more events), and a recurrent out-of-hospital cardiac arrest (OHCA), defined as an IHCA after being hospitalized for an index OHCA. Using multivariable hierarchical logistic regression models, rates of survival to discharge and favorable neurological survival (discharge CPC score of 1) between patients with recurrent IHCA and those with no recurrent IHCA and recurrent OHCA were compared. Results: Overall, 165,446 (86.1%) had no recurrent IHCA, 23,643 (12.3%) had recurrent IHCA, and 3162 (1.6%) had recurrent OHCA. Patients with no recurrent IHCA were ol...
