Abstract: A prospective study was made of 59 surgery patients (21 females, 38 males; mean age, 50.4) to determine the predictive value of various current techniques for assessing nutritional status (NS). Pre-operative clinical NS was judged by 2 different examiners (without laboratory data) using only routine history and physical examination (subjectively judging the patient to be of normal NS, or mildly, or significantly malnourished). Each patient also received a complete pre-operative objective (laboratory analysis) NS assessment. Based on the results of these 2 examinations, the accuracy of 5 NS assessment techniques for predicting a nutrition-associated complication (namely, infection) was evaluated. Individual or statistically combined objective measurements could not differentiate patients having low and high risks for infection. Subjective nutritional assessment by examiners and the prognostic nutritional index (PNI) NS assessment technique statistically predicted the potential for developing an infectioin. (wz)
