The median length of stay was 4 days (range 2\u201333 days) and 35 patients (4%) were readmitted in the first 30 days following index TJA, the majority of whom had a surgical site infection (SSI) (74%). The following factors were independently associated with increased costs: SSI, preoperative warfarin therapy, American Society of Anesthesiologists score of 3 or 4, hip TJA, increasing operation time, increasing postoperative blood transfusion requirements, other nosocomial infections, postoperative venous thromboembolism (VTE), pressure ulcers, postoperative confusion, and acute urinary retention. Based on data from the present study, the cost of TJA in Australia is estimated to exceed $1 billion AU per year. Preventable postoperative complications were major cost drivers: SSI and VTE added a further $97 million AU and $66 million AU, respectively, to arthroplasty costs in the first 30 days following surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This unique study has identified important factors influencing TJA costs and providing guidance for future research and resource allocation.<\/jats:p><\/jats:sec>","DOI":"10.1002\/acr.22523","type":"journal-article","created":{"date-parts":[[2014,12,2]],"date-time":"2014-12-02T20:33:48Z","timestamp":1417552428000},"page":"782-790","source":"Crossref","is-referenced-by-count":85,"title":["Direct Hospital Cost Determinants Following Hip and Knee Arthroplasty"],"prefix":"10.1002","volume":"67","author":[{"given":"T.
