Observational Study
Lactate and hypotension as predictors of mortality after in-hospital cardiac arrest.
Guidance on post-cardiac arrest prognostication is largely based on data from out-of-hospital cardiac arrest (OHCA), despite clear differences between the OHCA and in-hospital cardiac arrest (IHCA) populations. Early prediction of mortality after IHCA would be useful to help make decisions about post-arrest care. We evaluated the ability of lactate and need for vasopressors after IHCA to predict hospital mortality. ⋯ Post-ROSC lactate and need for vasopressors may be helpful in stratifying mortality risk in patients requiring mechanical ventilation after IHCA.

To identify factors associated with the initial rhythm in patients with in-hospital cardiac arrest and to assess whether potential differences in outcomes based on the initial rhythm can be explained by patient and event characteristics. ⋯ In this study, specific patient and cardiac arrest characteristics were associated with initial rhythm in patients with in-hospital cardiac arrest. However, differences in patient and cardiac arrest characteristics did not fully explain the association with survival for initial shockable rhythm compared to a non-shockable rhythm.

With bystander AED usage being critical for prehospital cardiac arrest patient outcomes, it is important to analyze if the gender and location disparities found in bystander CPR rates also exist for bystander AED usage. ⋯ Female patients are less likely to receive bystander AED usage compared to male patients. To resolve these disparities increased public awareness is necessary that supports AED usage on females as socially acceptable and necessary for patient outcomes. Furthermore, given bystander AED usage among males and females declined as cardiac arrest locations became more remote, improvements in rural and frontier AED availability and training are necessary to increase bystander AED usage rates in those regions.
