This preprint used the National Inpatient Sample to track in-hospital mortality after CPR for in-hospital cardiac arrest in US adults from 2016 to 2022, adjusting for demographic, socioeconomic and hospital characteristics. Overall mortality was 67.8%, with adjusted odds lower in 2019 (aOR 0.89) and higher in 2020 (1.18) and 2021 (1.26) than in 2016. Adjusted odds were also higher for Black (1.14), Hispanic (1.20) and self-pay patients (1.62).
Why it is interesting: Adjusted mortality after in-hospital cardiac arrest rose in the pandemic years and had not returned to pre-pandemic levels by 2022, with a gradient by insurance status and ethnicity.
