The geriatric 8 score as a predictor of postoperative outcomes in elderly patients undergoing esophagectomy.

Development and validation of a multivariable risk score for postoperative complications in urological surgery in older patients: FRAC cohort study.

A multivariable risk score incorporating SPPB alongside key clinical variables predicts 30-day postoperative complications in older urological patients and provides valuable objective frailty assessment for preoperative risk stratification.

Association Between Preoperative Prognostic Nutritional Index and Delirium After Spine Surgery in the Elderly: A Retrospective Analysis.

STUDY DESIGN This is a retrospective case-control study. OBJECTIVE This study hypothesized that a low preoperative prognostic nutritional index (PNI) would increase the risk of postoperative delirium in such patients and aimed to prove it. SUMMARY OF BACKGROUND DATA Postoperative delirium in elderly patients result...

Elderly age and the risk of postoperative complications in elective abdominal surgery: results of the multicenter study STOPRISK

Older age (65–75 years) is an independent predictor of postoperative complications and mortality following elective abdominal surgery, increasing the risk of complications 1.7-fold and the risk of death 2.2-fold after confounder adjustment.

Predictors of postoperative complications in elderly patients undergoing pulmonary lobectomy: a retrospective cohort study

A risk score based on age ≥70 years, ACCI ≥6, and preoperative anemia effectively stratifies elderly patients by their risk of major complications after pulmonary lobectomy, though external validation is warranted.

Association between preoperative oral frailty and postoperative infectious complications in patients undergoing colorectal cancer surgery: a retrospective analysis using the oral frailty index-8.

Modified 5-Item Frailty Index Is Associated with Postoperative Delirium but Not Survival in Patients Undergoing Surgery for Oral Squamous Cell Carcinoma

Because this retrospective study was limited by sample size, comorbidity-driven mFI-5 scoring, non-standardized delirium screening, and potential residual confounding, mFI-5 should be interpreted as a convenient screening marker rather than a stand-alone predictor.
