研究目的:

本研究旨在通过随机对照试验,系统比较阿司匹林和利伐沙班在单侧初次全膝关节置换术(TKA)或全髋关节置换术(THA)患者术后症状性VTE预防中的效果。研究的主要目的是评估阿司匹林在术后90天内预防症状性VTE发生率方面是否不劣于利伐沙班。此外,本研究还将检验两组在术后90天内出血事件等安全性指标、临床并发症发生率、患者依从性以及医疗资源使用等方面的差异,以提供个体化VTE预防策略的进一步证据支持。  

Objectives of Study:

This study aims to systematically compare the efficacy of aspirin and rivaroxaban in the prevention of symptomatic venous thromboembolism (VTE) after unilateral primary total knee arthroplasty (TKA) or total hip arthroplasty (THA) through a randomized controlled trial.The primary objective of the study is to evaluate whether aspirin is non-inferior to rivaroxaban in preventing the incidence of symptomatic VTE within 90 days postoperatively.In addition, the study will examine the differences between the two groups regarding safety outcomes, such as bleeding events within 90 days postoperatively, clinical complication rates, patient adherence, and healthcare resource utilization, to provide further evidence supporting individualized VTE prevention strategies.

药物成份或治疗方案详述:

在所有研究地点中,标准化的干预措施包括术后使用间歇性肢体气压治疗,直至患者能够主动活动为止,以及在术后当日或第1天开始的早期活动。 全膝关节置换术(TKA)患者: 阿司匹林组:口服阿司匹林100 mg,每日两次,疗程为14天。 利伐沙班组:口服利伐沙班10 mg,每日一次,疗程为14天。 全髋关节置换术(THA)患者: 阿司匹林组:口服阿司匹林100 mg,每日两次,疗程为35天。 利伐沙班组:口服利伐沙班10 mg,每日一次,疗程为35天。 

Description for medicine or protocol of treatment in detail:

At all study sites, standardized interventions included the use of postoperative intermittent pneumatic compression until the patient could mobilize independently, as well as early mobilization starting on the day of surgery or the first postoperative day. Total knee arthroplasty (TKA) patients: Aspirin group: Oral aspirin 100 mg, twice daily, for a duration of 14 days. Rivaroxaban group: Oral rivaroxaban 10 mg, once daily, for a duration of 14 days. Total hip arthroplasty (THA) patients: Aspirin group: Oral aspirin 100 mg, twice daily, for a duration of 35 days. Rivaroxaban group: Oral rivaroxaban 10 mg, once daily, for a duration of 35 days.

随机方法(请说明由何人用什么方法产生随机序列):

本研究利用中央随机化系统将患者分配至阿司匹林组或利伐沙班组,采用分层和区组随机化以确保均衡性。分层因素包括参与研究的四家医院(新疆医科大学第一附属医院,西安市红会医院,四川大学华西医院,浙江大学医学院附属第二医院),以减少中心效应。 中央随机化系统:系统根据预定的分层因素和区组要求进行随机分配,确保每个中心的患者均衡分布于两个治疗组。 分层随机化:在每个中心内,患者根据其接受的手术类型进行分层,确保不同手术类型患者的均匀分布。 区组随机化:通过区组设计,确保治疗组内患者数量均衡,减少中心间的偏倚。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study used a central randomization system to allocate patients to either the aspirin group or the rivaroxaban group, employing stratified and block randomization to ensure balance.Stratification factors included the four hospitals participating in the study (First Affiliated Hospital of Xinjiang Medical University, Honghui Hospital of Xi'an, West China Hospital of Sichuan University, and Second Affiliated Hospital of Zhejiang University School of Medicine) to minimize center effects.Central Randomization System: The system randomly assigns patients based on predefined stratification factors and block requirements to ensure balanced distribution of patients across the two treatment groups at each center.Stratified Randomization: Within each center, patients are stratified according to the type of surgery they receive to ensure an even distribution of patients with different types of surgery.Block Randomization: Block design ensures balanced patient numbers within the treatment groups, reducing bias between centers.

盲法:

评估者盲法:虽然患者和治疗医生知道分配的治疗方案,但所有结果评估者将对治疗分配保持盲态。 保密性:系统会记录每一次随机化操作,并确保随机分配过程的隐蔽性和数据的完整性。

Blinding:

Assessor Blinding: Although patients and treating physicians are aware of the assigned treatment plan, all outcome assessors will remain blinded to the treatment allocation.Confidentiality: The system records each randomization operation and ensures the concealment of the random allocation process and the integrity of the data.
