Continue routine nutritional care and reassess if clinical status or intake changes.

SNAQ is a screening instrument, not a definitive diagnosis. Interpret alongside clinical assessment, nutritional history, current intake, body mass index, disease context, and local protocols.

About the hospital SNAQ

The Short Nutritional Assessment Questionnaire is a brief screening tool developed to identify adult hospital patients who may be malnourished. The hospital version uses unintentional weight loss, decreased appetite, and use of supplemental drinks or tube feeding.

Score interpretation

ScoreClassificationOriginal linked action
0–1Well nourished by screening classificationNo specific intervention indicated by the score alone
2Moderately malnourishedNutritional intervention

For weight loss, select the higher applicable category rather than adding the 2-point and 3-point options together. The score is capped at the single highest applicable weight-loss criterion, plus the other applicable items.

Clinical scope

This implementation represents the hospital malnutrition screening SNAQ. It is not the four-item Simplified Nutritional Appetite Questionnaire, which has a different scoring method and a score threshold of 14.

Clinical disclaimer: This calculator supports nutritional screening and does not replace comprehensive nutritional assessment or clinical judgment. A positive screen should prompt assessment and management according to the patient's condition and local protocols. Confirm that this hospital SNAQ version is appropriate for the target population and language before clinical deployment.
