Trends in Management and Mortality in Adults Hospitalized With Cardiac Arrest in the United States

Background:We sought to examine temporal trends in management (ie, use of extracorporeal membrane oxygenation [ECMO], therapeutic hypothermia [TH], coronary angiogram, and percutaneous coronary intervention [PCI]) and in-hospital mortality in adults hospitalized with cardiac arrest.Methods:Utilizing the Nationwide Inpatient Sample, medical history, clinical management, and in-hospital mortality were assessed in 942 495 hospitalizations in adults with cardiac arrest (identified through International Classification of Diseases-9 codes) from 2006 to 2012.Results:From 2006 to 2012, there was an overall rise in the use of coronary angiogram (12.8%, 13.0%, 14.7%, 15.0%, 14.3%, 14.7%, and 15.8%), PCI (7.5%, 7.1%, 8.4%, 8.1%, 8.1%, 8.4%, and 8.9%), TH (0.2%, 0.3%, 0.6%, 1.2%, 1.9%, 2.8%, and 3.0%), and ECMO (0.1%, 0.1%, 0.1%, 0.2%, 0.2%, 0.3%, and 0.4%; P < .001 for all). In-hospital mortality significantly decreased over the 7-year study period (65.5%, 63.4%, 59.3%, 57.9%, 57.0%, 56.0%, and 56.3% from 2006 to 20...
