Refeeding Syndrome Risk Assessment

Assess refeeding syndrome risk before initiating nutrition in at-risk patients. High-risk features (any 2 minor or 1 major): BMI below 16, unintentional weight loss above 15% in 3-6 months, minimal intake above 10 days, low baseline phosphate/potassium/magnesium. High risk requires thiamine supplementation, electrolyte monitoring, and slow caloric advancement (10-20 kcal/kg/day initially).
