Investigators developed a negative binomial regression model using the Get With The Guidelines-Resuscitation (GWTG-R) registry to estimate the incidence of index pulseless in-hospital cardiac arrest based on hospital-level characteristics. Investigators then applied the model to predict in-hospital cardiac arrests using data from the AHA annual survey.
Investigators performed separate analyses for groups of adult and pediatric patients(less than 18 years old) for cardiac arrest. Investigators also performed additional analyses to evaluate rates of recurrent cardiac arrests and pediatric patients requiring cardiopulmonary resuscitation for poor perfusion.
From the 398 GWTG-R hospitals identified, investigators estimated the average incidence across all hospitals in the US between 2008 and 2017 was 292,000 cases per year. Investigators noted that these results were similar when adding the number of admissions to the model in the post hoc analysis. When including both index and recurrent events, investigators estimated that the average annual incidence between 2008 and 2017 was 357,900.
After analyses, investigators estimated that the average national nonpulseless event incidence was estimated at 8100 cases per year. When including both index and recurrent nonpulseless events, the average annual incidence was estimated at 11,600 cases. The overall national pediatric in-hospital event incidence was calculated at 15,200 cases per year.
