The Effect of Nutritional Status on Postoperative Mortality and Morbidity in the Geriatric Population Undergoing Gastrointestinal Surgery
Sponsor: Dr. Lutfi Kirdar Kartal Training and Research Hospital
Summary
The purpose of this study was to compare the sensitivity and specificity of the Geriatric Nutritional Risk Index (GNRI), Mini Nutritional Assessment Scale-Short Form (mNA-SF) and Systemic Immune-Inflammatory Index (SII) values calculated in the preoperative evaluation in patients over 65 years of age who underwent gastrointestinal surgery, in predicting morbidity and mortality in the postoperative period.

Interventions
Preoperative Risk Scoring
Patients will be evaluated preoperatively using three distinct scoring systems: the Geriatric Nutritional Risk Index (GNRI), the Mini Nutritional Assessment-Short Form (mNA-SF), and the Systemic Immune-Inflammation Index (SII). These scores are calculated based on serum albumin levels, body weight, a 6-question survey, and laboratory values (platelets, neutrophils, and lymphocytes).
Postoperative Morbidite and Mortality Monitoring
Systematic tracking of postoperative outcomes including hospital and ICU stay duration, pulmonary complications (e.g., pneumonia, embolism), extrapulmonary complications (e.g., surgical site infection, organ failure, delirium), and mortality rates at 30, 60, and 90 days.
Delirium Assessment Protocol
Patients will be monitored for delirium preoperatively, on the first postoperative day, and before discharge using the Confusion Assessment Method (CAM/CAM-ICU) and the Richmond Agitation-Sedation Scale (RASS).
