IMPACT OF NUTRITIONAL STATUS ON OUTCOMES AFTER LIVER TRANSPLANTATION1

BACKGROUND Poor preoperative nutritional status has been reported to be associated with adverse outcomes after liver transplantation. Published data are, however, conflicting, with methods of preoperative nutritional assessment and postoperative outcomes varying between studies. METHODS We prospectively studied the predictive value of preoperative nutritional status for adverse outcomes after liver transplantation. Assessment of preoperative nutritional status included: body cell mass determination, subjective global assessment, anthropometry, handgrip dynamometry, biochemical and amino acid profile, Child's score, and dual-energy x-ray absorptiometry. Death, intensive care unit (ICU) length of stay > or =4 days, hospital length of stay > or =15 days, blood usage > or =36 U of blood products, infection, rejection, and global resource utilization (an index of cost) greater than the median were considered poor outcomes. RESULTS Fifty-three patients were studied. Longer ICU stay was associated with lower handgrip strength (P
