ABSTRACT
BACKGROUND AND AIMS: The aim of this study is to establish whether serum albumin concentration at the beginning of parenteral nutrition is related to morbidity and mortality. METHODS: In this cohort study spanning four years, a number of patients were classified into twelve groups, depending on their clinical status at the beginning of parenteral nutrition. Their serum albumin concentration and other clinical parameters were then measured and twelve multiple logistic regression models were thus generated in order to model the relationship between initial albumin concentration and risk of morbidity/mortality. RESULTS: 1953 (84%) of the 2321 patients studied were hypoalbuminemic. In six models, this condition was associated with a significant increase in the risk of nosocomial infection. However, no model could be associated to significant risk of renal failure, and only patients with previous hepatopathy were at risk for hepatic failure. In seven models, there was a significant increase in mortality. CONCLUSIONS: Serum albumin concentration at the beginning of parenteral nutrition is related to mortality and morbidity associated with nosocomial infection in some groups of the study.
