The association between hemoglobin at admission and mortality of older patients with hip fracture: a mean 3-year follow-up cohort study

Key summary points Aim To evaluate the association between hemoglobin concentration at admission and mortality of older patients with hip fractures. Findings The hemoglobin at admission was nonlinearly associated with mortality of older patients with hip fractures, and hemoglobin at admission < 9.8 g/dL was a risk predictor of 3-year mortality. Message The hemoglobin level at admission is an essential predictive indicator, and this study provides implications for clinical practice of evaluating hemoglobin at admission for hip fractures.
