Abstract The relationship between preoperative hyponatremia and 30-day outcomes following total hip arthroplasty (THA) is currently unknown. present study used prospectively collected data to quantify the association odds of major morbidity (MM), longer length stay, readmission, reoperation within 30 days THA. Patients who underwent THA 2012 2014 were identified in National Surgical Quality Improvement Program database using validated Current Procedural Terminology codes. included if they either normonatremic or hyponatremic preoperatively. outcome measures this MM, hospital reoperation. A unique multivariable logistic regression model was for each identify statistically significant associations interest after adjusting covariates. From 2014, 59,236 procedures recorded Program, which 55,611 patients 3,051 hyponatremic. After covariates, significantly associated with increased MM (odds ratio [OR] = 1.14; 99% confidence interval [CI]: 1.01–1.30), (OR 1.18; CI: 1.02–1.36), stay 1.20; 1.13–1.27). Hyponatremia not greater readmission 0.91; 0.82–1.01). Preoperative adverse As U.S. health care system continues transition toward value-based reimbursement that emphasizes quality, results can be improve patient selection counseling.
