Warren JA, George J, Anis HK, et al. - Using the National Surgical Quality Improvement Program (NSQIP) database, researchers identified 101,925 primary THAs between January 1, 2008, and December 31, 2016 to explore the connections between estimated glomerular filtration rate’s (eGFR), both as a categorical and continuous variable and 30-day outcomes and complications. Findings suggested that lower eGFR patients, particularly those < 30 ml/ min/ 1.73 m² are more likely to sustain medical complications and have 6 to 9 times higher mortality than normal eGFR patients. Several major complications and minor complications as well as several specific medical complications like transfusion and myocardial infarction for an eGFR < 60 ml / min/1.73 m² increased risk. THA candidate patients with chronic kidney disease should be properly advised and eGFR should be used to monitor and advise on postoperative complications risk.
