The Nutrition Risk in the Critically Ill (NUTRIC) score is a tool used to estimate the risk of 28-day mortality in critically ill patients by assessing various clinical factors. This score is computed by considering six key parameters, each contributing a specific value to the total score. The higher the total, the greater the patient's risk of mortality.

Here are the inputs and their corresponding scores:

- Age, years:
  - "< 50": 0 points
  - "50-74": 1 point
  - ">= 75": 2 points

- APACHE II score:
  - "< 15": 0 points
  - "15-19": 1 point
  - "20-27": 2 points
  - ">= 28": 3 points

- SOFA score:
  - "< 6": 0 points
  - "6-9": 1 point
  - ">= 10": 2 points

- Number of comorbidities:
  - "0-1": 1 point
  - ">= 2": 1 point

- Days from hospital to ICU admission:
  - "0": 0 points
  - ">= 1": 1 point

- IL-6, mc/mL:
  - "0-399": 0 points
  - ">= 400": 1 point

To calculate the NUTRIC score, assign points to each input based on the above categories and sum these points. The total score can range from 1 to 10, with each score indicating a different risk of 28-day mortality:

- Score 0: 1% risk of mortality
- Score 1: 2% risk of mortality
- Score 2: 3% risk of mortality
- Score 3: 8% risk of mortality
- Score 4: 11% risk of mortality
- Score 5: 20% risk of mortality
- Score 6: 30% risk of mortality
- Score 7: 45% risk of mortality
- Score 8: 58% risk of mortality
- Score 9: 70% risk of mortality
- Score 10: 80% risk of mortality

Each score provides a clear prediction of the patient’s likelihood of mortality within 28 days, helping guide critical care decisions.

The Nutrition Risk in the Critically Ill (NUTRIC) score is a clinical calculator used to assess the nutritional risk and predict the outcomes of critically ill patients, particularly those in the intensive care unit (ICU). This scoring system is designed to help clinicians identify patients who would benefit most from aggressive nutritional support. The NUTRIC score includes factors such as age, Acute Physiology and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment (SOFA) score, number of comorbidities, and days from hospital to ICU admission. It does not require subjective assessments of nutritional status, making it particularly useful in the ICU setting. There are no specific exclusion criteria for its use, but it is most applicable to patients who are critically ill and at high risk of malnutrition.
