Abstract
Background
Critically ill non-trauma patients treated in the emergency department have a high risk of in-hospital mortality. While point-of-care diagnostics such as blood gas analysis are established tools for urgent management, data on their prognostic value in this specific patient cohort remain limited. This study aimed to evaluate whether initial blood gas parameters are independently associated with in-hospital mortality in critically ill non-trauma patients.
Methods
This retrospective cohort study included adult critically ill non-trauma patients treated in the emergency department of a German university hospital. Initial blood gas parameters and clinical data were analyzed using univariate and multivariable logistic regression to assess their association with in-hospital mortality.
