ASPEN consensus criteria for identifying adult patients at risk for RS

Moderate risk (2 risk criteria need to be met) Significant risk (1 risk criterion needs to be met)
Body mass index (kg/m2) 16.0–18.5 <16.0
Weight loss 5% in 1 month 7.5% in 3 months or >10% in 6 months
Caloric intake None or negligible oral intake for 5–6 days OR <75% of estimated energy requirement for >7 days during an acute illness or injury OR <75% of estimated energy requirement for >1 month None or negligible oral intake for >7 days OR <50% of estimated energy requirement for >5 days during an acute illness or injury OR <50% of estimated energy requirement for >1 month
Abnormal prefeeding potassium, phosphorus, or magnesium serum concentrations Minimally low levels or normal current levels and recent low levels necessitating minimal or single-dose supplementation Moderately/significantly low levels or minimally low or normal levels and recent low levels necessitating significant or multi-dose supplementation
Loss of subcutaneous fat Evidence of moderate loss Evidence of severe loss
Loss of muscle mass Evidence of mild or moderate loss Evidence of severe loss
Higher-risk comorbidities Moderate disease Severe disease
