ICU-Acquired Weakness Likelihood Assessment

Assess likelihood of ICU-acquired weakness (ICUAW) using MRC sum score of 6 bilateral muscle groups and identify modifiable risk factors including duration of immobility, corticosteroids, and hyperglycemia.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess likelihood of ICU-acquired weakness (ICUAW) using MRC sum score of 6 bilateral muscle groups and identify modifiable risk factors including duration of immobility, corticosteroids, and hyperglycemia

Each component has a specific meaning:

  • Identify modifiable risk factors including duration of immobility — The identify modifiable risk factors including duration of immobility recorded for the scenario being assessed.
  • Corticosteroids — The corticosteroids recorded for the scenario being assessed.
  • Hyperglycemia — The hyperglycemia recorded for the scenario being assessed.

Note: Interpret the icu weakness assessment result against the thresholds and context described above.

How to Use

Enter the identify modifiable risk factors including duration of immobility, corticosteroids, hyperglycemia for the scenario you are assessing. Assess likelihood of ICU-acquired weakness (ICUAW) using MRC sum score of 6 bilateral muscle groups and identify modifiable risk factors including duration of immobility, corticosteroids, and hyperglycemia. Use the icu weakness assessment result to inform your calculation.
