This process includes dietary, anthropometric, and biochemical aspects. Nutritional assessment begins with a detailed nutritional history that includes clinical, dietary, socioeconomic, and family issues. Areas of interest include present and past illnesses, family illness history, food allergies or intolerance, medications, nutritional supplements, over-the-counter medications, alcohol use, work environment, and education level. A useful standardized protocol is the Prognostic Nutritional Index (PNI), which incorporates serum albumin, serum transferrin, delayed skin hypersensitivity, and triceps skinfold thickness (20,21). The PNI has been shown to correlate with postoperative complications and mortality (22). Whole body functional assessment by examining overall activity, exercise tolerance, grip strength, respiratory function, wound healing, and plasma albumin concentration can also be useful.
