Cardiac arrest & resuscitation

The association between time of in hospital cardiac arrest and mortality; a retrospective analysis of two UK databases

ResuscitationPublished Retrospective cohort study

Authors' conclusion

We observed higher rates of IHCA, and poorer outcomes at night. However, in those admitted to ICU, this variation was absent.
