Hsiue PP, et al. - Researchers sought to compare the outcomes after hemiarthroplasty (HA) for femoral neck fractures (FNF) among patients with predialysis chronic kidney disease (CKD) or end-stage renal disease (ESRD) vs those with no kidney disease. Via retrospectively reviewing the Nationwide Readmissions Database, they identified 214,399 patients who underwent HA after FNF between 2010 and 2014 and divided these into 3 groups using ICD-9 diagnosis codes: no kidney disease (n = 176,300, 82%), predialysis CKD (n = 34,400, 16%), and ESRD (n = 3,698, 2%). Outcomes revealed worse outcomes in terms of mortality risk, blood transfusion, and postoperative complications during the index hospitalization as well as an increased risk of 90-day hospital readmission after HA for FNF among both ESRD and CKD patients relative to patients with no kidney disease.
