Acute cardiac care & resuscitation
Updating the model for Risk-Standardizing survival for In-Hospital cardiac arrest to facilitate hospital comparisons
Authors' conclusion
We have derived and validated an updated model to risk-standardize hospital rates of survival for IHCA. The updated model yielded RSSRs that were similar to the initial model for IHCAs in the pre-pandemic period
Study context
