Reporting on Glucose Control Metrics in the Intensive Care Unit

Area of Science:

• Critical care medicine
• Endocrinology
• Metabolic disorders

Background:

• The 'diabetes of injury' in critical illness is better understood due to therapeutic advances.
• Severe hyperglycemia, hypoglycemia, and high glycemic variability are linked to increased mortality and complications in acutely ill patients.

Purpose of the Study:

• To emphasize the need for standardized metrics in managing dysglycemia in critical illness.
• To advocate for the prevention of severe hyperglycemia, hypoglycemia, and glycemic variability.

Main Methods:

• Review of recent therapeutic advances and large cohort studies on dysglycemia in critical illness.
• Analysis of current guidelines recommending avoidance of specific dysglycemic states.
• Proposal of common metrics, such as time in target blood glucose range, for quantitative assessment.

Main Results:

• Dysglycemic events (hyperglycemia, hypoglycemia, variability) are associated with adverse outcomes.
• Current guidelines support avoiding these dysglycemic domains.
• A unifying metric like time in target range is proposed for consistent evaluation.

Conclusions:

• Standardized language and metrics are crucial for managing critical illness-related dysglycemia.
• Future research should define optimal blood glucose targets based on patient-specific factors.
• Technological advancements in glucose monitoring and therapy should be evaluated using consistent metrics.
