PO-05-163 INCIDENCE AND RHYTHM PRESENTATION OF IN-HOSPITAL VERSUS OUT-OF-HOSPITAL SUDDEN CARDIAC ARREST AND PREDICTORS OF READMISSION AT 90 DAYS

Sudden cardiac arrest (SCA) may culminate in sudden death (SCD) if resuscitation efforts are unsuccessful or absent. The pathogenesis and system of care for in-hospital out-of-hospital (IHCA OHCA) different. We sought to determine predictors readmission these patients presenting with SCA surviving discharge. All >18 years age from 2016-2019 were included. Data abstracted using the International Classification Diseases 10th Revision-Clinical Modification Nationwide Readmissions Database (NRD). Patient demographics, presence comorbidities, rhythm, evaluated. Out 51,998,206 admissions between 2016 2019, 35,050 (0.07%) presented SCA. IHCA was commoner than OHCA [21,347 (60.9%) vs 13,703 (39.1%)]. Patients younger [67 69 years, p <0.0001] had overall lower systemic comorbidities [Charlson’s comorbidity index (CCI) – OHCA: 2.0 (1.0-3.0) IHCA: (1.0-4.0) points, P<0.0001]. Pulseless electrical activity (PEA) predominant rhythm but much higher group [overall: 68.6%, 51.5% 95.4%, p<0.0001]. Ventricular arrhythmia (VA) [ventricular tachycardia (VT), ventricular fibrillation (VF)] as compared [OHCA: 2,878 (29.9%) 6,761 (70.1%), Of getting admitted SCA, 26,080 (74.41%) died at first admission, a mortality [IHCA 15,690 (73.5% mortality) 10,390 (75.82% mortality), At 90-day follow-up, percentage PEA 3,012 (90.9%) vs. 2,573 (45.5%), p<0.0001] similar admission. Young predicted readmissions whereas diabetes mellitus renal diseases rates both groups (P<0.0001). irrespective type admission well readmission. Younger (<60 years) more likely get readmitted, which is alarming needs proper evaluation this cohort prevent recurrences reduce among survivors.
