详细说明
临床问题:服用华法林或直接口服抗凝剂(DOAC)的患者的管理以及需要进行选修手术/手术是一个常见且重要的临床问题:(i)在加拿大评估了约200,000名患者/YR的患者/YR的管理人员,并且由于年龄的人口和抗癌药物的增加而增加了这种管理; (ii)如果未仔细管理抗凝剂,则使用基于证据的方案进行管理,如果抗凝剂中断过长或危及生命的出血,则可能会暴露于破坏中风的风险,如果中断太短。
医疗保健提供问题:传统上,抗凝治疗的围手术期管理是在面对面的环境中进行的,患者会收到有关何时停止和重新启动抗凝剂的指示,并在需要时接受教学以自我管理肝素桥梁。 COVID大流行已经颠覆了这种医疗保健交付模型,需要通过电话/视频进行虚拟管理。 虚拟患者护理管理围手术期抗凝治疗的潜力有效,患者友好的后大流行。 但是,要实现这一目标,必须可靠地表明,实际上是标准化的,围手术期的抗凝治疗的是:(i)安全性,中风和出血率很低; (ii)在实践中易于应用; (iii)患者可以接受。
申请人的工作为暂停虚拟的基础提供了基础:这项研究的基础是基于我们先前的工作:(i)我们领导了多中心临床试验(桥梁,暂停),这些试验为接受华法林或DOAC的患者提供安全围手术管理提供了基准; (ii)将这些试验的管理方案纳入了加拿大血栓形成(www.thrombosiscanada.ca)的临床决策工具中。 此应用点应用程序允许输入特定于患者的信息,以管理接受华法林或DOAC的心房颤动/颤动(AF)的单个患者,并且需要进行选修课/手术。 在评估结束时,可以作为PDF提供护理路径摘要,用于临床医生和患者下载和印刷。
机会:大流行需要采用虚拟围手术期抗凝剂管理,但也提供了重新评估如何安全地提供此类护理的机会。 鉴于(i)围手术期抗凝剂中断/恢复和肝素桥接协议已标准化,并且(ii)有一个易于使用的,即护理点的服务点,管理应用程序,我们有一个独特的机会,我们有一个独特的机会,可以与用户友好的知识易解工具一起使用证据信息,以评估虚拟扰流器管理的患者的安全性和可接受性。
解决方案:一项前瞻性队列研究(非RCT),评估2个需要选择性手术/手术的华法林患者或DOAC的标准化虚拟围手术管理。
假设和假设:(i)我们假设虚拟围手术期管理对患者护理是安全的,术后为30天的中风/系统性栓塞率(SSE)≤0.5%,大量出血(MB)≤1.5%。 在队列1中的样本量为847例,在队列2中,我们将在95%的显着性水平上具有90%的功率,以拒绝SSE观察到的速率≥1.5%,而每个队列中MB≥3%。 (ii)我们假设(a)虚拟管理将与接受基准的人工管理管理的匹配的历史控制小组一样安全,(b)虚拟管理将降低患者的医疗保健成本和成本,以及(c)患者对虚拟管理的满意度并将愿意接受这种医疗保健后提供这种医疗保健后流行病学后。
意义:暂停虚拟会将围手术期抗凝剂的管理从资源密集型的亲自模型转移到患者友好的虚拟模型,为加拿大为200,000名患者/年建立了标准的护理选项。 我们是全球围手术期抗凝剂管理的领先小组,他完成了Landmark Bridge1和Pape2试验。 没有其他研究小组(我们知道)可以进行此试验,并且不会由行业资助(没有商业利益)。

研究人员将确定30天的后期过程事件发生率,并以95%的置信区间(CI)进行中风/全身性栓塞(SSE),主要出血(MB),并在单方面的二项式测试中确定同类率1和队列2,如果SSE速率低于1.5%,并且MB速率低于3%。
研究人员将比较患者人群(例如,年龄,性别)和临床特征(例如手术类型,SSE/MB风险)1 vs。
控制1和队列2 vs。
对照2分别使用Fisher精确测试,以比较同类和对照中的SSE和MB,并使用多变量逻辑回归调整了关键协变量(例如,手术类型,抗凝类型,性别,性别,性别)。
研究人员将确定虚拟护理中患者满意度类别的比例(和95%CI),并愿意接受未来的虚拟护理。

To demonstrate that virtual management is safe, as defined by 30-day postoperative rates of stroke/systemic embolism (SSE) of ≤0.5% and major bleeding (MB) of ≤1.5% with ability to exclude rates of SSE and MB of 1.5% and 3.0%, with a sample of 847 patients in Cohorts 1 and 2, the investigator will have 90% power at the 95% level of significance to reject the无效假设,即SSE的观察率为≥1.5%,MB≥3.0%。
该样本量为847的样本量增加了5%,每个队列(总计1,780例),以说明取消的手术/程序,并丢失了随访的患者。
