The aim of this clinical narrative review was to summarise the existing knowledge on the use of anticoagulants and potential adverse events in older people at risk of falls with a history of atrial fibrillation or venous thromboembolism. The review also offers practical steps prescribers can take when (de-)prescribing anticoagulants to maximise safety.
Literature searches were conducted using PubMed, Embase and Scopus. Additional articles were identified by searching reference lists.
Anticoagulants are often underused in older people due to concerns about the risk of falls and intracranial haemorrhage. However, evidence suggests that the absolute risk is low and outweighed by the reduction in stroke risk. DOACs are now recommended first line for most patients due to their favourable safety profile. Off-label dose reduction of DOACs is not recommended due to reduced efficacy with limited reduction in bleeding risk. Medication review and falls prevention strategies should be implemented before prescribing anticoagulation. Deprescribing should be considered in severe frailty, limited life expectancy and increased bleeding risk (e.g., cerebral microbleeds).
When considering whether to (de-)prescribe anticoagulants, it is important to consider the risks associated with stopping therapy in addition to potential adverse events. Shared decision-making with the patient and their carers is crucial as patient and prescriber views often differ.
本临床叙事综述旨在总结目前关于有房颤或静脉血栓栓塞病史的老年人中使用抗凝剂和潜在不良反应的知识。该综述还提供了临床医生在开具或停用抗凝剂时可以采取的实用步骤,以最大程度地保证安全。
使用 PubMed、Embase 和 Scopus 进行文献检索。通过检索参考文献列表,还确定了其他文章。
由于担心跌倒和颅内出血的风险,抗凝剂在老年人中常常使用不足。然而,有证据表明,绝对风险较低,且低于卒中风险的降低。由于其良好的安全性,目前建议大多数患者首选 DOAC。不建议 DOAC 的标签外剂量减少,因为疗效降低而出血风险降低有限。在开具抗凝药物之前,应进行药物审查和跌倒预防策略。在严重虚弱、预期寿命有限和出血风险增加(例如脑微出血)的情况下,应考虑停药。
在考虑是否开具或停用抗凝剂时,除了考虑潜在的不良反应外,还需要考虑停止治疗相关的风险。与患者及其照顾者共同决策至关重要,因为患者和医生的观点往往不同。
