b"2024 DATASETUTSTEIN SURVIVALThe Utstein template was developed by international resuscitation experts to establish uniform reporting guidelines for clinical variables and patient outcomes related to OHCA. These guidelines define core data fields to ensure consistency in terminology and provide recommendations on the data elements to be recorded for each OHCA event.Patients who experience a bystander witnessed OHCA and present in a shockable rhythm are the most likely to survive their arrest and are referred to as the Utstein subgroup. This subset of arrests serves as an important measure of system efficacy, allowing for comparison of patient outcomes between systems and time periods, despite the wide variation of cardiac arrest circumstances and patient characteristics.Figure 20 presents the National CARES Utstein Survival Report for 2024, which stratifies arrests by witness status and presenting rhythm. In 2024, the survival to hospital discharge rate for the Utstein subgroup was 33.4%. Utstein bystander patients (arrests witnessed by a bystander, presenting in a shockable rhythm, and receiving some bystander intervention [CPR and/or AED application]) had a survival rate of 37.6%.-Utstein Survival ReportAll Agencies/National DataDate of Arrest: 01/01/24-12/31/24-Resuscitations Attempted Non-Traumatic Etiology Survival Rates140598 Overall: 10.5% (137119)Bystander Wit'd: 16.0%(51419)Unwitnessed: 4.5% (68840)Trauma Etiology Utstein: 33.4% (14844)3479 Utstein Bystander: 37.6% (9007)Bystander Intervention Rates Non-Traumatic Etiology CPR: 41.7% (102682)137119 Public AED Use: 12.6% (18037)Unwitnessed Arrest Witnessed by 911 Responder68840 16859*see page 2 Witnessed by Bystander *see page 351419Initial Rhythm Asystole Initial Rhythm VF/VT Other Initial Rhythm19112 14844 17463Sustained ROSC in field = 4163 Sustained ROSC in field = 7138 Sustained ROSC in field = 6376Died in Field Died in Field Died in Field9054 2497 5188Died in ED Died in ED Died in ED6069 4731 6096Admitted to Hospital Admitted to Hospital Admitted to Hospital3989 (22 incomplete) 7616 (59 incomplete) 6179 (58 incomplete)Died In Hospital Died In Hospital Died In Hospital3235 2601 3557Discharged Alive Discharged Alive Discharged Alive732 4956 2564Neurological Status Neurological Status Neurological StatusCPC 1 or 2 CPC 1 or 2 CPC 1 or 2371 4353 1972CPC 3 or 4 CPC 3 or 4 CPC 3 or 4360 603 59144 Unknown = 1 Unknown = 0 Unknown = 1Figure 20. 2024 CARES Non-Traumatic Etiology Utstein Survival Report."
