Objective:

To investigate the association between stress hyperglycemia ratio (SHR) levels and prognosis in patients undergoing invasive mechanical ventilation (IMV) and to explore how SHR may inform specific treatment strategies, such as glycemic control interventions.

Key Findings:

• Elevated SHR levels correlate with increased mortality risk in patients undergoing IMV, indicating a need for enhanced monitoring.
• The optimal SHR cutoff for predicting one-year all-cause mortality was identified, which could guide clinical interventions.
• SHR may serve as a valuable prognostic marker to guide clinical decision-making, particularly in managing glycemic levels.

Interpretation:

The findings suggest that SHR is a significant predictor of mortality in critically ill patients on IMV, highlighting its potential utility in risk assessment and treatment optimization.

Limitations:

• The study is based on a retrospective analysis, which may introduce biases that affect the generalizability of the findings.
• Data limitations include potential inaccuracies in laboratory measurements and missing HbA1c values, which could impact SHR calculations.

Conclusion:

SHR could enhance risk assessment and inform treatment strategies for patients undergoing IMV, warranting further prospective studies to validate these findings and explore its application in clinical practice.
