Implementation of PENN Arthroplasty Risk Score (PARS) as Predictors of the Need for Critical Care After Total Joint Arthroplasty in Sanglah General Hospital

Background: The purpose of this study was to know the implementation of Penn arthroplasty risk score (PARS) as predictors of the need for critical care after total joint arthroplasty in Sanglah General Hospital. Methods: Fifty-five patients who undergoing total hip replacement and total knee replacement at our institution between September 2019 and August 2020 are included to this study. The condition of patient pre and post operatively is calculated with PARS score. The PARS score of all patient then matches with decision of anaesthesiologist whether the patient is admitted to the intensive care unit post operatively or not. Results: In total of 55 patients undergoing total joint arthroplasty, there were 10 (18.2%) patients admitted to intensive care unit and 45 (81.8 %) patients admitted to ward postoperatively. Based on PARS score, there were 9 patients undergoing total joint arthroplasty who had score ≥ 3 of PARS score and all of those patients were matched with anaesthesiologist decision of administration of intensive care post operatively. Conclusion: The present study concluded that PARS score could be one of predictors of the need for critical care after total joint arthroplasty. A larger prospective study or may be a multicentre trial can further improve the interpretation of the results. Keywords: PARS score, intensive care, total joint arthroplasty, THR, TKR
