    PurposeFailure to rescue (FTR) is defined as mortality within 30 days following a major complication. While FTR has been studied in various brain tumor resections, its predictors in malignant brain tumor resection (mBTR) remain unexplored. This study aims to identify FTR predictors in mBTR resection patients using a frailty-driven model.MethodsPatients undergoing craniotomy for mBTR were identified from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database (2012- 2020), with frailty measured by the Risk Analysis Index (RAI).ResultsOf 14,721 mBTR patients, 1,275 (8.66%) developed major postoperative complications, and 166 (13.01%) experienced FTR. The cohort's median age was 59, interquartile range (47-68). Multivariate analysis revealed non-elective surgery (OR: 1.48, 95% CI: 1.02-2.16, p<.05) as an independent risk factor for FTR. Frailty was a significant independent predictor of FTR with mBTR, with both frail (N=110) and very frail (N=22) patients having a 5.34-fold and 8.10-fold higher odds of FTR, respectively (p<.001). Expectedly, major postoperative complications were predictive of FTR, including unplanned intubation (OR: 2.56, CI: 1.66-3.95, p<.001), prolonged ventilation (OR: 2.00, CI: 1.37-3.14, p<.01), cardiac arrest (OR: 16.64, CI: 8.20-33.74, p<.001), and septic shock (OR: 2.08, CI: 1.10-3.91, p<.05). The RAI-driven frailty model demonstrated excellent discriminatory accuracy for predicting FTR patients undergoing mBTR (c-statistic: 0.82, 95% CI: 0.79-0.85).ConclusionPreoperative RAI-measured frailty, alongside non-elective surgery and major postoperative complications were significant predictors of FTR in mBTR patients. Identifying mBTR patients at risk for FTR using frailty strata may aid in preoperative neurosurgical risk stratification to optimize patients prior to surgery.Copyright © 2025 The Author(s).
