The Five-item Modified Frailty Index is Predictive of 30-day Postoperative Complications in Patients Undergoing Spine Surgery

This study aimed to evaluate the utility of the modified frailty index (mFI-5) in a population of patients undergoing spine surgery. Summary of Background Data. The original modified frailty index (mFI-11) published as an American College of Surgeons National Surgical Quality Improvement Program 11-factor index was modified to mFI-5 after variables were removed from recent renditions. Methods. Surgical spine patients were isolated using current procedural terminology codes. mFI-11 (11) and mFI-5 (5) were calculated from 2005 to 2012. mFI was determined by dividing the factors present by available factors. To assess correlation, Spearman rho was used. Predictive values of indices were generated by binary logistic regression. Patients were stratified into groups by mFI-5: not frail (NF, 0.5). Means comparison tests analyzed frailty and clinical outcomes. Results. After calculating the mFI-5 and the mFI-11, Spearman rho between the two indices was 0.926(P
