This study characterizes the patient and clinical factors influencing the economic burden of periprosthetic joint infection (PJI) in the United States. The 2001-2009 Nationwide Inpatient Sample was used to identify total hip and knee arthroplasties using International Classification of Diseases, Ninth Revision, procedure codes. The relative incidence of PJI ranged between 2.0% and 2.4% of total hip arthroplasties and total knee arthroplasties and increased over time. The mean cost to treat hip PJIs was $5965 greater than the mean cost for knee PJIs. The annual cost of infected revisions to US hospitals increased from $320 million to $566 million during the study period and was projected to exceed $1.62 billion by 2020. As the demand for joint arthroplasty is expected to increase substantially over the coming decade, so too will the economic burden of prosthetic infections.
本研究旨在描述影响美国人工关节置换术后感染（PJI）经济负担的患者和临床因素。研究使用了 2001-2009 年全国住院患者样本，通过国际疾病分类第九版手术代码来确定全髋关节和膝关节置换术。PJI 的相对发病率在全髋关节置换术和全膝关节置换术之间的 2.0%至 2.4%范围内，并呈上升趋势。治疗髋关节 PJI 的平均费用比治疗膝关节 PJI 的平均费用高出 5965 美元。在研究期间，美国医院因感染而进行的翻修手术的年度成本从 3.2 亿美元增加到 5.66 亿美元，预计到 2020 年将超过 16.2 亿美元。由于未来十年对关节置换术的需求预计将大幅增加，因此假体感染的经济负担也将增加。
