The aim of this study was to determine the annual in-hospital mortality rates of patients with cardiac arrest from 2001-2009. Methods and Results -The U.S. mortality rates for hospitalized patients with cardiac arrest were determined using the 2001-2009 U.S. National Inpatient Sample (NIS), a national hospital discharge database. Using the International Classification of Diseases, 9 th Revision code 427.5, we identified patients hospitalized in the U.S. with cardiac arrest from 2001-2009. The main outcome measure was in-hospital mortality. A total of 1,190,860 patients were hospitalized with a diagnosis of cardiac arrest in the U.S. from 2001-2009. The in-hospital mortality rate decreased each year from 69.6% in 2001 to 57.8% in 2009. In multivariable analyses, when controlling for age, gender, race, and co-morbidities, earlier year was a strong independent predictor of inhospital death. The mortality rate declined across all analyzed subgroups, including gender, age, race, and stratification by comorbidity. Conclusions -The in-hospital mortality rate of patients hospitalized with cardiac arrest in the U.S. decreased by 11.8% from 2001-2009. we identified patients hospitalized in the U.S. with cardiac arrest from 2001-2009 09 9.
