The Total Joint Arthroplasty Cardiac Risk Index for Predicting Perioperative XXXX and @entity1167 After Primary Total Knee and Hip Arthroplasty.

BACKGROUND: Current indices fail to consistently predict risk for major adverse @entity299 after major @entity2720 . METHODS: All primary @entity348 ( @entity348 ) and @entity572 ( @entity572 ) were identified from the National Surgical Quality Improvement Program data set. Based on prior analyses, age >= 80 years, history of @entity101 , and history of @entity299 were evaluated as predictors of @entity583 and @entity1167 using stepwise multivariate logistic regression. A series of predictive scores were constructed and weighted to identify the influence of each variable on 30-day postoperative @entity299 , while comparing with the Revised Cardiac Risk Index (RCRI). RESULTS: Among 85,129 @entity1 , age >= 80 years, @entity101 , and a history of @entity299 were all statistically significant predictors of postoperative @entity299 (0.32%; n  = 275) after @entity348 and @entity572 (P   <= .02). Equal weighting of all variables maintained the highest discriminative capacity in both @entity572 and @entity348 cohorts. Adjusted models explained 75% and 71% of the variation in postoperative @entity299 for those with @entity572 and @entity348 , respectively, without statistically significant lack of fit (P  = .52; P  = .23, respectively). Conversely, the RCRI was not a significant predictor of postoperative @entity299 after @entity348 (odds ratio, 3.36; 95% CI, 0.19, 58.04; P  = .40), although it maintained a similar discriminative capacity after @entity572 (76%). CONCLUSION: The current @entity2720 Cardiac Risk Index score was the most economical in predicting @entity260 after primary unilateral @entity348 and @entity572 . The RCRI was not a significant predictor of perioperative @entity299 for @entity348 @entity1 but performed similarly to the current model for @entity572 .
