The Risk Analysis Index Has Superior Discrimination Compared With the Modified Frailty Index-5 in Predicting Worse Postoperative Outcomes for the Octogenarian Neurosurgical Patient

Abstract

We found that RAI was a more accurate predictor than mFI-5 and increasing patient age for 30-day mortality, eLOS, and pLOS in octogenarian neurosurgery patients. More research is needed on RAI's performance in different specialized neurosurgical populations. Moreover, it is increasingly clear that comprehensive risk assessment strategies tailored to optimize perioperative care should be prioritized to potentially improve outcomes for this at-risk population.
