Factors Associated with Survival to Hospital Discharge in Cardiac Arrest by Poisoning: WAIVOR Score.

ABSTRACT:

Introduction

Poisoning-induced out-of-hospital cardiac arrest (P-OHCA) is a leading mortality cause; however, no specific prognostic model exists for P-OHCA. In this study we aimed to develop and validate a novel scoring system, the WAIVOR score, which identifies factors associated with survival to hospital discharge in patients with P-OHCA, including the nature of the toxic agent.

Methods

In this retrospective nationwide observational study we analyzed 4,252 South Korean adult P-OHCA cases from 2013-2023. The study population was randomly stratified into derivation (n = 2,834) and validation (n = 1,418) cohorts. Independent factors associated with survival to hospital discharge were identified through multivariable logistic regression analysis, yielding adjusted odds ratios
