Purpose
Patients sustaining a hip fracture have a high mortality rate during the first postoperative year and the Sernbo score may stratify patients into a high, intermediate and low risk of death during this period. We assessed its predictive properties on patients from the National Swedish Hip Fracture Register.
Patients and methods
55,716 hip fracture patients, 69% women older than 65 years at surgery (registered between 2010 and 2015) with complete Sernbo scores and mortality data were studied. Receiver-operating characteristics analyses (ROC) were used. Validation of Sernbo score was performed.
Results
The overall 1-year mortality rate was 26%—and 17%, 27.4% and 55.6% in the low, intermediate and high-risk groups, respectively. The ROC analysis indicated a predictive ability of the Sernbo score, with an AUC of 0.69 (CI 0.68–0.69).
Conclusion
In this registry-based study, the easy-to-use Sernbo scoring system proved to be appropriate and useful way to identify hip fracture patients with a high-risk mortality during the first postoperative year.
