Abstract

Purpose: To assess whether the Nottingham Hip Fracture Score (NHFS) can predict mortality in the first 30 days after surgery. Material and methods: Upon admission, 216 patients were assessed for age, sex, mobility status, bedridden, assisted or unassisted walking, living accommodations (residence or institutionalized), fracture type (intra- or extracapsular), comorbidities (cardiovascular, stroke, respiratory, renal, diabetes), malignant disease, and cognition (Mini-Mental Status Examination). We applied the NHFS, which evaluates seven factors, with scores ranging from 0 to 10, as a predictor of 30-day mortality after hip surgery. Results: Survivor scores had greater variability (CV = 0.28) than non-survivors (CV = 0.20). The receiver operating characteristic curve identified a score of 5.5 as the optimal cutoff point. At this point, the test’s sensitivity and specificity indicates the simultaneous maximum likelihood of 30-day survival or non-survival. Conclusion: NHFS is a robust predictor of 30-day mortality after hip surgery and, an updated equation, it has been validated for the patients in this sample, increasing its clinical credibility.
