Abstract 248: Current Status Of In-hospital Cardiac Arrest And Issues Of Collecting Data Using The Latest In-hospital Utstein-style Reporting Templates

[Background]: The outcome of in-hospital cardiac arrest has improved over the past decade, although the survival rate is still approximately 25%. The in-hospital Utstein-style reporting templates were international standard template for in-hospital cardiac arrest, with items to be substantially revised in 2019, with recommendations for standardization of records to allow objective comparisons. The aim of this study is to analyze the current status of in-hospital cardiac arrest in our hospital, and to clarify the issues in collecting the data using the in-hospital Utstein-style reporting templates. [Methods]: We collected the reports of 3 years in-hospital cardiac arrests occurred between April 2019 and March 2022 in our hospital. We described all reported items and their proportion (Patient, Pre-event, Cardiac arrest process, Post-resuscitation process, and Outcome), and calculated the missing rate of each item. [Results]: A total of 106 cases during the study period, and all reports were submitted by nurses. The median age was 74 years old (IQR: 64-81), 60.4% were male, 76.4% of cases were witnessed, chest compressions were 67.9%, and shock delivered were in 5.9%. The initial shockable rhythm was in 15.1% of cases (Table). Some items had missing data or invalid responses. Date and time of event, initial rhythm, the time of first shock delivered, and 30 days outcome had missing data (rate of missing 33%, 13.2%, 44.4%, and 80.7%, respectively), which were core items of the latest in-hospital Utstein-style reporting templates. Patient category, post-resuscitation process, reason for CPR stopped, and neurological outcome at 30 days were not measured. [Conclusions]: The high rate of missing data is considered that the nurses may not understand the meaning of the items, and suggested the need for education of nurses who submit reports.
