Objective:

To investigate the independence of the Shock-Lactate Index (SLI) in predicting 28-day mortality in patients with sepsis-associated renal injury and assess its clinical utility, particularly in guiding treatment decisions.

Key Findings:
  • Shock-Lactate Index (SLI) is a significant predictor of 28-day mortality in patients with sepsis-related AKI, highlighting its potential role in clinical settings.
  • Higher SLI values correlate with increased mortality risk, indicating a need for close monitoring.
  • Dynamic monitoring of lactate levels enhances early identification of high-risk patients, potentially improving outcomes.
Interpretation:

The SLI combines heart rate, blood pressure, and lactate levels to provide a more sensitive measure for predicting mortality in critically ill patients with sepsis-related AKI, surpassing traditional metrics.

Limitations:
  • Retrospective design may introduce selection bias, potentially affecting the reliability of the findings.
  • Data derived from a single-center database may limit generalizability, necessitating further multi-center studies.
Conclusion:

The Shock-Lactate Index is a valuable tool for predicting mortality in sepsis-associated AKI, aiding in timely clinical decision-making.
