Comprehensive Summary
Tan et al. analyzed MIMIC-IV data (2008–2019) to identify clinical predictors of hypothermia in patients with septic shock, aiming to improve early risk stratification in critical care. Among 1,640 ICU patients with septic shock, 134 (8.2%) developed hypothermia, highlighting a clinically significant high-risk subgroup. Univariate logistic regression was used to identify key risk factors associated with hypothermia in septic shock patients, guiding subsequent predictive modeling. Five independent predictors: hemoglobin, heart rate, respiratory rate, lactate, and dopamine use, were strongly associated with hypothermia in septic shock patients. These variables were incorporated into a nomogram predicting hypothermia risk, with an AUC of 0.787, demonstrating robust internal validation and potential bedside applicability. This model reliably stratifies septic shock patients by hypothermia risk, supporting timely interventions in the ICU.
Outcomes and Implications
Hypothermia in septic shock was associated with higher mortality. The identified variables enable a predictive nomogram to stratify risk and guide early interventions. While internal validation was strong, external validation is needed. This study demonstrates the potential of data-driven models to enhance sepsis management by identifying high-risk patients earlier.
