The Impact of Preoperative Nutritional Status of Elderly Patients on the Postoperative Outcome: Comparison of Two Nutritional Assessment Tests and Biochemical Tools

Özet

BACKGROUND/AIMS Our main goal was to compare the two validated nutritional screening tools and serum proteins that are used as routine biochemical markers for the prediction of the postoperative outcome. MATERIAL and METHODS The current study was design to evaluate the prevalence of malnutrition among elderly patients undergoing elective curative gastrointestinal cancer and trochanteric hip fracture surgery. On admission to the preoperative holding area, all patients underwent the two nutritional screening tests: Mini Nutritional Assessment (MNA) and Nutritional Risk Screening 2002 (NRS − 2002). After assessment, all participants were followed-up throughout their hospital stay. We calculated the lymphocyte-monocyte ratio (LMR) and albumin-globulin ratio (AGR) according to the laboratory results. The surgical outcome (discharge to ward/intensive care) and postoperative infection (systemic or surgical site) were recorded. RESULTS The group of patients with MNA 17. The mean serum albumin and globulin levels and the AGR was comparable between before and after the surgery. However, the mean LMR was significantly lower than the preoperative value. CONCLUSION Measurements with easy-to-perform tests will provide guidance in terms of identifying potential perioperative risks.
