ObjectivesTo describe in-hospital cardiac arrest (CA) events with regard to sex and to investigate if sex is associated with survival.BackgroundPrevious studies exploring differences between sexes are incongruent with regard to clinical outcomes. In order to provide equality and improve care, further investigations into these aspects are warranted.MethodsThis registry study included 286 CAs. To investigate if sex was associated with survival, logistic regression analyses were performed.ResultsThe proportion of CA with a resuscitation attempt compared to CA without resuscitation was higher among men. There were no associations between sex and survival when controlling for previously known predictors and interaction effects.ConclusionsSex does not appear to be a predictor for survival among patients suffering CA where resuscitation is attempted. The difference regarding proportion of resuscitation attempts requires more attention. It is important to consider possible interaction effects when studying the sex perspective.Copyright © 2014 Elsevier Inc. All rights reserved.
