Arrest Outcome Consortium Registry Analysis [AOCRA 2022] Outcome Statistics of Cardiac Arrest in Tertiary Care Hospitals in India, Analysis of Five Year Data of Indian Online Cardiac Arrest Registry, www.aocregistry.com

Aim and background: To publish data with outcome statistics from our online cardiac arrest (CA) outcome consortium (AOC) online registry.Materials and methods: Data on cardiac arrest (CA) from tertiary care hospitals were collected on the AOC registry online portal from January 2017 to May 2022. Survival endpoints from cardiac arrest events like ROSC, and survival at hospital discharge with neurological status at discharge were analyzed and presented. Studies of demographics, the association of outcome with age, gender, bystander CPR, low and no flow times, and admission lactate were also done along with suitable statistical analysis.Results: Out of 2,235 CA, 2,121 received CPR (1,998 IHCA, 123 Out of hospital Cardiac Arrest (OHCA)) as 114 were DNR. The males-female ratio was 70:30. Average age at arrest was 58.7 years. 26% OHCA received bystander CPR but survival advantage was not significant. (with 16%, without 14% p = 0.78). Asystole (67.7%), Pulseless Electrical Activity (PEA) (25.6%), and VF/pVT (6.7%) as first rhythm significantly influence survival (4.9, 8.6 and 39.4%: p < 0.001) ROSC was achieved in 355 (16.7%), with 173 (8.2%) alive and 141 (6.6%) having good (CPC <= 2) neurological state at discharge. At discharge, survival as well as CPC <= 2 outcomes were significantly better in females. On multivariate regression analysis, first rhythm and low flow time influence survival at discharge. Admission lactate (available only in 102 OHCA) was lower in survivors than non-survivors 10.3 vs 11.5 mmol/L but the difference was not statistically significant (p = 0.397].Conclusion: Data from our AOC registry shows poor overall survival from CA. The Female gender had a higher survival rate. Ventricular Fibrillation/ Pulseless Ventricular Tachycardia (VF/pVT) as first rhythm and low flow time influence the survival to discharge (CTRI/2022/11/047140).
