Impact of extracorporeal cardiopulmonary resuscitation on outcomes of elderly patients who had out-of-hospital cardiac arrests: a single-centre retrospective analysis

ObjectivesLittle is known about the effectiveness of extracorporeal cardiopulmonary resuscitation (ECPR) for elderly patients who had out-of-hospital cardiac arrest (OHCA). The aim of this study was to examine the impact of age on outcomes among patients who had OHCA treated with ECPR.DesignSingle-centre retrospective cohort study.SettingA critical care centre that covers a population of approximately 1 million residents.ParticipantsPatients who had consecutive OHCA aged ≥18 years who underwent ECPR from 2005 to 2013.Primary and secondary outcome measuresPrimary outcomes were 1 month neurologically favourable outcomes and survival. To determine the association between advanced age and each outcome, we fitted multivariable logistic regression models using: (1) age as a continuous variable and (2) age as a categorical variable (
