Thirty-Day Complications of Conventional and Computer-Assisted Total Knee and Total Hip Arthroplasty: Analysis of 103,855 Patients in the American College of Surgeons National Surgical Quality Improvement Program Database

Aims The aim of this study was to assess the influence of operating time on 30-day complications following total hip arthroplasty (THA). Patients and Methods We identified patients aged 18 years and older who underwent THA between 2006 and 2016 from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. We identified 131 361 patients, with a mean age of 65 years (sd 12), who underwent THA. We used multivariable regression to determine if the rate of complications and re-admissions was related to the operating time, while adjusting for relevant covariables. Results The mean operating time decreased from 118.3 minutes (29.0 to 217.0) in 2006, to 89.6 minutes (20.0 to 240.0) in 2016. After adjustment for covariables, operating times of between 90 and 119 minutes increased the risk of minor complications by 1.2 (95% confidence interval (CI) 1.1 to 1.3), while operating times of between 120 and 179 minutes increased the risk of major complications by 1.4 (95% CI 1.3 to 1.6) and minor complications by 1.4 (95% CI 1.2 to 1.5), and operating times of 180 minutes or more increased the risk of major complications by 2.1 (95% CI 1.8 to 2.6) and minor complications by 1.9 (95% CI 1.6 to 2.3). There was no difference in the overall risk of complications for operating times of between 20 and 39, 40 and 59, or 60 and 89 minutes (p > 0.05). Operating times of between 40 and 59 minutes decreased the risk of re-admission by 0.88 (95% CI 0.79 to 0.97), while operating times of between 120 and 179 minutes, and of 180 minutes or more, increased the risk of re-admission by 1.2 (95% CI 1.1 to 1.3) and 1.6 (95% CI 1.3 to 1.8), respectively. Conclusion These findings suggest that an operating time of more than 90 minutes may be an independent predictor of major and minor complications, as well as re-admission, following THA, and that an operating time of between 40 and 90 minutes may be ideal. Prospective studies are required to confirm these findings. Cite this article: Bone Joint J 2019;101-B(6 Supple B):51–56.

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