Abstract:
The incidence of in-hospital cardiac arrest (IHCA) has increased over the past decade, with more than half occurring in intensive care units (ICUs).[1] ICU cardiac arrest (ICU-CA) presents unique challenges, with worse outcomes than those in monitored wards, highlighting the need for early detection and intervention.[2] Up to 80% of patients exhibit signs of deterioration hours before IHCA.[3] Although early warning scores based on vital signs are useful, their effectiveness in ICUs is limited due to abnormal physiological parameters.[4] Laboratory markers, such as sodium, potassium, and lactate, are predictive of poor outcomes,[5] but static measurements may not capture the patient’s trajectory. Trends in laboratory indicators, such as variability and extremes, may offer better predictive value.[6] This study aimed to evaluate ICU-CA predictive factors, with a focus on vital signs and trends of laboratory indicators.
