Prediction of postoperative complications by clinical and nutritional assessment.
This study evaluated a battery of nutritional measures and pre-operative clinical assessment as predictors of postoperative morbidity. Fifty-seven consecutive patients about to undergo major elective abdominal or thoracic surgery were surveyed. Thirty-two per cent of patients had three or more abnormal measurements of nutritional indices. Thirty patients had a total of 52 complications and in 12 patients these were major. The Prognostic Nutritional Index (PNI), formulated by Mullen, was found to be the best predictor of postoperative outcome. It identified 10 of 12 (83%) patients who subsequently developed major complications with a specificity of 73%. Clinical assessment selected six of the 12 patients who developed major complications.
