Key result
The Nottingham Hip Fracture Score showed acceptable discrimination (AUC 0.71; 95% CI 0.67-0.75) for 30-day mortality, whereas the Surgical Outcome Risk Tool was miscalibrated (P=0.001).
Why the study?

Population
9,017 elderly patients with hip fractures from a multicentre national dataset

NHFS supports risk stratification in hip fracture patients; leaves open the need for SORT recalibration.
Observational (n=9,017)
Yes
Do the Nottingham Hip Fracture Score and Surgical Outcome Risk Tool accurately predict 30-day mortality after hip fracture surgery?
Effect estimate: AUC 0.71 (95% CI 0.67-0.75)
The Nottingham Hip Fracture Score provides acceptable discrimination and calibration for predicting 30-day mortality after hip fracture surgery, outperforming the calibration of the Surgical Outcome Risk Tool.
Marufu et al. (2016) conducted an observational in Hip fracture (n=9,017). Nottingham Hip Fracture Score vs. Surgical Outcome Risk Tool was evaluated on Death at 30 postoperative days (AUC 0.71, 95% CI 0.67-0.75). The Nottingham Hip Fracture Score showed acceptable discrimination (AUC 0.71; 95% CI 0.67-0.75) for 30-day mortality, whereas the Surgical Outcome Risk Tool was miscalibrated (P=0.001).
