Malnutrition is a common comorbidity in patients undergoing thoracic surgery. Furthermore, chronic diseases, polypharmacy, low nutrient intake, reduced appetite, and psychological factors-all frequently observed in geriatric patients-serve as risk factors for the development of nutritional deficiencies. Consequently, it is crucial to address the issue of malnutrition in geriatric patients-who often present with these risk factors-and to ensure that a nutritional status assessment is performed prior to thoracic surgery. While numerous screening tools are currently available to assess nutritional status in the elderly, there is no established "gold standard." Although it has been suggested that these nutritional screening tools can serve as prognostic indicators for geriatric surgical patients, the relationship between these tools and postoperative outcomes-such as pain, complications, and length of hospital stay-has not yet been fully evaluated in geriatric patients undergoing lung resection. This study aims to determine the relationship between preoperative nutritional status and postoperative outcomes in patients undergoing lung resection-an area lacking sufficient literature-and to investigate whether preoperative nutritional support can reduce postoperative complications in this patient population.Patients will undergo preoperative assessment, and data regarding those meeting inclusion criteria will be recorded. This includes routine blood tests, age, height, body weight, BMI, gender, diagnoses, ASA and ARISCAT scores, the surgery performed, durations of surgery/anesthesia/one-lung ventilation, intraoperative fluids and IV agents administered, fluid balance, any complications arising during the procedure or postoperative follow-up (up to discharge), Visual Analog Scale (VAS) scores at postoperative hours 1, 2, 4, 8, 16, and 24, Charlson Comorbidity Index, Clinical Frailty Scale (CFS), and nutritional status (GNRI, NRS-2002, PNI, MNA-SF).

the correlation between preoperative nutritional status and postoperative results in geriatric patients undergoing lung resection by thoracotomy.
The primary outcome variable of the study is the evaluation of the correlation between preoperative nutritional status and postoperative outcomes in geriatric patients undergoing lung resection by thoracotomy.Patients will be evaluated preoperatively and patients who meet the inclusion criteria will have routine blood tests, age, height, body weight, BMI, gender, diagnoses, ASA and ARISCAT scores, surgery performed, duration of surgery/anesthesia/single lung ventilation, fluid and iv agents administered intraoperatively, fluid balance, advanced complications, if any, during the procedure or during postoperative follow-up until discharge, postoperative 1., 2., 4., 8., 16. and 24. visual Analog Scale(VAS), Charlson Comorbidity Index, Clinical Frailty Scale(CFS), nutritional status of GNRI, NRS-2002, PNI, MNA-SF and forms will be recorded by filling out
Time frame: after surgery up to 30 days
comparison of the indicated nutritional risk screening tools in terms of the predictability of postoperative outcomes in geriatric patients who will undergo lung resection with thoracatomy.
The nutritional screening tools such as nutritional status of GNRI, NRS-2002, PNI, MNA-SF will be compared to determine which one is better at predicting postoperative outcomes.
Time frame: after surgery up to 30 days
Plan to share: No
Start is estimated for Nov 2026; primary completion for Oct 2027, 11 months later.
