Abstract
PurposeLittle is known about long-term survival after In-Hospital Cardiac Arrest (IHCA). The purpose of this study is to report the one-year survival of patients after IHCA and to identify predicting factors. MethodsSingle-center retrospective study of all adult in-hospital CPR attempts conducted between 2003 and 2014 in a tertiary teaching hospital. Demographic and clinical variables of patients were obtained at 24 h pre-arrest, during CPR and post-CPR. All patients were tracked one year after discharge from hospital. ResultsCPR was performed for IHCA on 417 patients. Return of spontaneous circulation (ROSC) was achieved in 283 (68%) patients, 234 were admitted to ICU. Overall, 95 (23%) patients survived one year after discharge, The survival rate of patients who were admitted to ICU after IHCA was 38% (89/234) at hospital discharge and 26% (61/234) at one year. Univariate analysis showed numerous variables are associated with one-year survival, for example comorbidity index and time to ROSC. DiscussionOne-year survival of patients admitted to the ICU after IHCA was 26%. Severity of disease pre-arrest and at ICU-admission could prove useful in prognostication. No multivariate model could be constructed and large prospective studies are needed to elicit the role of pre-arrest factors on survival.
