Overview
Brief inpatient screen for malnutrition based on weight loss, appetite and supplements/tube feeding.
Clinical Significance
Use the result to support structured assessment, not as a standalone diagnosis or treatment decision.
When to Use
- Use when a structured assessment with this validated instrument is clinically appropriate.
How It Is Calculated
- Item values are summed and mapped to the published interpretation bands.
Interpretation
- Interpret the score with clinical findings, collateral information and current guidance.
Worked Example
Select a verified response for each item; MedicalC sums the assigned values and displays the interpretation band.
Limitations
- Screening and severity scales do not establish a diagnosis by themselves.
- Language, cognition, acute illness and setting can affect responses.
Clinical Pearls
- Document individual responses as well as the total score.
- Escalate immediately when an item identifies urgent risk, regardless of the total.
Common Mistakes
- Using incomplete responses.
- Ignoring item-specific red flags because the overall score is low.
