Pediatric anesthesia & critical care
Incidence, outcomes, and temporal trends of pediatric in-hospital cardiac arrest in Japan: a nationwide study
Authors' conclusion
Using an administrative chest compression procedure code, we identified a declining incidence of IHCA and improving survival in Japan.
