The prevalence of venous thromboembolism (VTE) after total joint arthroplasty (TJA) is 0.40%-1.2%. Trends in TJA are for shorter hospital stays with lower complication rates. The aim of this study is to evaluate whether hospital length of stay (LOS) is associated with risk of a thromboembolic event after TJA.
This was a retrospective study of patients undergoing TJA during 2013-2017 at Louisiana and Texas hospitals. Univariable analyses and multivariable logistic regression examined patient characteristics (sex, race, age, body mass index, Charlson Comorbidity Index, TJA type, and LOS) associated with experiencing a VTE event after discharge and before 1-year follow-up.
Of the 13,969 patients who met inclusion criteria, 338 (2.4%) had a VTE event after discharge. In multivariable regression analysis, more severe comorbidities (odds ratio: 1.30, 95% confidence interval: 1.23-1.37; < .001) and LOS days (odds ratio: 1.07, 95% confidence interval: 1.01 to 1.14; = .0215) were associated with an increased risk of VTE.
Patients with more severe comorbidities or a longer LOS had a greater risk of VTE after discharge following TJA.
全关节置换术（TJA）后静脉血栓栓塞症（VTE）的患病率为0.40%-1.2%。TJA的发展趋势是住院时间缩短，并发症发生率降低。本研究的目的是评估住院时间（LOS）是否与TJA后血栓栓塞事件的风险相关。
这是一项对2013年至2017年在路易斯安那州和得克萨斯州医院接受TJA治疗的患者进行的回顾性研究。单变量分析和多变量逻辑回归分析了与出院后至1年随访前发生VTE事件相关的患者特征（性别、种族、年龄、体重指数、Charlson合并症指数、TJA类型和LOS）。
在符合纳入标准的13969例患者中，338例（2.4%）出院后发生了VTE事件。在多变量回归分析中，更严重的合并症（比值比：1.30，95%置信区间：1.23-1.37；P<0.001）和住院天数（比值比：1.07，95%置信区间：1.01至1.14；P=0.0215）与VTE风险增加相关。
合并症更严重或住院时间更长的患者在TJA出院后发生VTE的风险更高。
