A potential novel predictor of 1-year mortality in elderly hip fracture patients-albumin haemoglobin index
Authors' conclusion
AHI is a potential novel predictor of 1-year mortality in elderly hip fracture patients, with prognostic performance comparable to RAR and superior to RDW.
Study context
- Population
- Patients aged ≥ 65 years who underwent hip fracture surgery, January 2020 to December 2021, managed in a Fracture Liaison Service
- Participants
- 775 patients
- Exposure
- Preoperative albumin haemoglobin index (AHI) vs other preoperative blood parameters (RDW/albumin ratio (RAR), RDW) for predicting 1-year mortality
- Outcome
- 1-year mortality
- Follow-up
- 1 year
Methodological detailsROC analysis, Cox proportional hazards models
- ROC analysis
- Cox proportional hazards models
