Acute cardiac care & resuscitationCohort study
Incidence, outcomes, and temporal trends of pediatric in-hospital cardiac arrest in Japan: a nationwide study
- nationwide study
- national administrative inpatient database
Authors' conclusion
Using an administrative chest compression procedure code, we identified a declining incidence of IHCA and improving survival in Japan. These findings require cautious interpretation because case ascertainment was code-based. A national registry is needed to validate administrative case identification and better characterize resuscitation processes and outcomes.
