1743 Frailty is associated with poor cardiopulmonary resuscitation outcomes in the COVID-19 pandemic

Abstract

Abstract Background This study aims to investigate the relationship between frailty and in-hospital cardiopulmonary resuscitation (CPR) outcomes in the COVID-19 pandemic. Methods The study was carried out in a tertiary hospital in Scotland and included all patients over the age of 18 who had an in-hospital CPR attempt between April 2020 and March 2022. Patients were identified via the pre-existing National Cardiac Arrest Audit Database which was collected prospectively. Data collected from this included age, sex, initial arrest rhythm, return of spontaneous circulation (ROSC) and in-hospital mortality. The electronic and paper patient notes were retrospectively reviewed to calculate a Rockwood clinical frailty scale (CFS) and Charlson comorbidity index (CCI). The data was stratified in to frail (CFS ≥5) and non-frail (CFS <5) groups. Results 65 patients were included in the study. In univariate analysis, there was a significant difference between the frail and non-frail groups in age (p=0.006), ROSC (p=0.02) and survival to discharge (p=0.004). Only 10 out of 34 (29.4%) frail patients had ROSC and of those only 3 (8.8%) survived to discharge compared to 12 out of 31 (35.3%) of non-frail patients. In a binary logistic regression, there was a significant association between frailty and both ROSC (adjusted OR 3.31 [95% CI: 1.12-9.78}) and survival to discharge (adjusted OR 6.33 [95% CI: 1.48-27.13]) and no significant association with age, CCI or sex. Conclusion The findings support the relationship between frailty and poor CPR outcomes independent of age and co-morbidity during the COVID-19 pandemic.
