Schuijt HJ, Smeeing DPJ, Würdemann FS, et al. - A multicenter prospective cohort study was designed to construct and validate a prediction model for in-hospital mortality in individuals with hip fracture 85 years of age or older undergoing surgery. Researchers included individuals with hip fracture 85 years of age or older undergoing surgery. It was shown that in patients with geriatric hip fracture, age, male gender, higher American Society of Anesthesiologists classification, and lower hemoglobin levels at presentation are robust independent predictors of in-hospital mortality and were incorporated in a simple prediction model with good accuracy and no lack of fit.
