Early-Stage Chronic Kidney Disease and Hip Fracture Mortality.

Chronic kidney disease (CKD) is a documented risk factor for hip fracture mortality. CKD represents a spectrum of disease and there is no clear evidence differentiating the risk between patients with early versus end-stage CKD. The purpose of this study was to explore the relationship between the stages of CKD and mortality following operative treatment of hip fractures. Four hundred ninety-eight patients were analyzed; 81 were identified as having CKD. This study followed overall patient mortality at 90 days and at 1 year postoperatively. Patients with CKD had higher mortality at both 90 days and 1 year compared with those without CKD (hazard ratio 1.69 and 1.84, respectively). In a subgroup analysis to determine the effect of CKD stage, only stage 3 CKD was associated with increased mortality. The orthopaedic surgeon can play a key role in identifying at-risk patients and help to facilitate additional management. (Journal of Surgical Orthopaedic Advances 27(3):226-230, 2018).
