Abstract 【Objective】 To explore the risk factors of poor prognosis at discharge in patients with out-of-hospital cardiac arrest (OHCA). 【Methods】 A retrospective analysis was conducted on the clinical data of 264 OHCA patients treated by Shanghai Songjiang District Medical Emergency Center from January 2022 to January 2024. According to the survival status at discharge, the patients were divided into survival group (n=182) and death group (n=82). Univariate analysis and multivariate Logistic regression analysis were used to screen the independent risk factors affecting the prognosis of patients at discharge. 【Results】 Univariate analysis showed that there were statistically significant differences between the survival group and the death group in bystander CPR, no-reflow time, CPR duration, epinephrine dosage, lactic acid level, APACHE Ⅱ score and WIC score (P<0.05). Multivariate Logistic regression analysis showed that no bystander CPR, no-reflow time > 5 min, CPR duration > 15 min, epinephrine dosage > 5 mg, high APACHE Ⅱ score, elevated lactic acid level and high WIC score were all independent risk factors for in-hospital death of OHCA patients (P<0.05). 【Conclusion】 The discharge prognosis of OHCA patients is closely related to bystander CPR implementation, no-reflow time, CPR duration, epinephrine dosage, APACHE Ⅱ score, lactic acid level and WIC score. Medical staff can carry out early intervention and optimize cardiopulmonary resuscitation measures according to the specific conditions of patients.
