Discriminatory Value of the Risk Analysis Index Versus the 5-Factor Modified Frailty Index for Major Outcome Measures in Degenerative Cervical Myelopathy

< 0.05). Sub-analysis by approach showed frailty had greater predictive accuracy for adverse outcomes in ADF compared to PDF.ConclusionsThe RAI-Rev demonstrated superior discrimination predicting non-fatal outcomes following DCM when compared to the mFI-5, with equivalent mortality prediction. Further, frailty plays a stronger role in predicting mortality and morbidity in ADF compared to frailty's impact on predicting outcomes with PDF. This finding demonstrates the utility of the RAI-Rev in preoperative risk stratification with an increasingly frail patient population and provides initial evidence for selecting posterior approaches for DCM patients as frailty increases.
