title: The adjunctive value of routine biochemistry in nutritional assessment of hospitalized patients.
abstract: Nutritional screening and assessment of patients are not part of the routine procedures at hospital admission, although a large percentage of patients is malnourished. Similarly, nutritional status of patients and dietary intake is usually not monitored during hospitalization. In contrast a great number of laboratory investigations for screening purposes accompanies most, if not all, hospital admissions. Several of those routine markers carry important nutritional information and could convey several aspects of patients' nutritional requirements. This review proposes that laboratories in particular could provide a service for the nutritional interpretation of available routine data which would help clinicians to focus on nutrition related problems. The nutritional meaning of basic physical characteristics (age, sex, height, and weight), urinary excretion of ketone bodies, urea and creatinine, and serum concentrations of urea, phosphate, iron and albumin are discussed in detail and the assessment of protein malnutrition, metabolism, and requirements is emphasized. Finally, a proposed sample layout for the nutritional interpretation of routinely available biochemical and basic physical data is presented.
