From the Research

Malnutrition Diagnosis

The Global Leadership Initiative on Malnutrition (GLIM) criteria are used for the diagnosis of malnutrition. However, the provided studies do not mention the "Lights criteria" for malnutrition.

GLIM Criteria

The GLIM criteria are a two-step approach for the diagnosis of malnutrition, which includes:

  • Screening to identify "at risk" patients by any validated nutritional screening tool (NST)
  • A detailed nutritional assessment for diagnosis and grading the severity of malnutrition 1 The GLIM criteria consider factors such as:
  • Anthropometric measurements
  • Assessment of dietary intake
  • Measurement of serum C-reactive protein (CRP) for inflammation 2

Validation of GLIM Criteria

Studies have validated the GLIM criteria for diagnosing malnutrition, showing satisfactory criterion validity 3 and high diagnostic accuracy 4. The GLIM criteria have been compared to other diagnostic tools, such as the Subjective Global Assessment (SGA) and the Mini Nutritional Assessment-Short Form (MNA-SF), and have been found to have better diagnostic value in some cases 4, 5.

Key Findings

  • The GLIM criteria have a high diagnostic accuracy for distinguishing patients with malnutrition, with a sensitivity of 0.72 and a specificity of 0.82 4
  • The presence of malnutrition by GLIM criteria is associated with adverse outcomes, such as prolonged hospitalization and increased risk of in-hospital deaths and death within six months 3, 5
  • The GLIM criteria should be applied in clinical practice for the diagnosis of malnutrition 3

Note: There is no mention of the "Lights criteria" in the provided studies. The information provided is based on the GLIM criteria for malnutrition diagnosis.
