title: A modified prognostic index based upon nutritional measurements.
abstract: This paper describes a formula which, on solution, derives a prognostic index (PI) for predicting surgical complications using an anthropometric measurement and serum protein levels which may be obtained easily and rapidly. The formula was applied to three groups of patients, firstly 106 patients undergoing major surgical resection, secondly to 16 patients admitted for minor surgery to assess a normal range, and thirdly 10 patients undergoing total parenteral nutrition. In patients undergoing major surgical resection the prognostic index was significantly greater in those patients developing complications than in the control group and a good predictor of the risk of complications. The index uses nutritional measurements to predict complications rather than being a measurement of nutritional status and is therefore a poor monitor of the efficacy of nutritional therapy.
