Certain medications have shown significant effectiveness in reducing the incidence of cardiovascular events and mortality, leading them to be among those that are prescribed most commonly for Canadian seniors. However, polypharmacy, which disproportionately affects older adults, is particularly concerning for frail individuals who are at higher risk for adverse medication-related events. The deprescribing process is the discontinuation, either immediate or gradual, of inappropriate medications, to address polypharmacy and improve outcomes. Nonetheless, the incorporation of deprescribing principles into clinical practice present challenges, including the limited amount of data available on the clinical benefits of deprescription, and a lack of consensus on how to deprescribe. The current narrative review explores frailty as a basis for deciding to deprescribe medication. The evidence regarding the benefits of use of medications prescribed for common cardiovascular conditions (including acetylsalicylic acid, statins, and antihypertensives) in older adults with frailty is reviewed. The review also examines the issue of who should initiate the deprescribing process, and the associated psychological implications. Although no one-size-fits-all approach to deprescription is available, patient goals should be prioritized. For older adults with frailty, healthcare professionals must consider carefully whether the benefits of use of a cardiovascular medication outweighs the potential harms. Ideally, the deprescribing process should involve shared decision-making among physicians, other health professionals, and patients and/or their substitute decision-makers, with the common goal of improving patient outcomes.
某些药物已显示出在降低心血管事件发生率和死亡率方面具有显著效果,这使得它们成为加拿大老年人最常开具的药物之一。然而,多重用药现象对老年人的影响尤为严重,对于那些发生药物相关不良事件风险较高的体弱个体而言,这尤其令人担忧。减药过程是指立即或逐步停用不适当的药物,以解决多重用药问题并改善治疗效果。尽管如此,将减药原则纳入临床实践仍面临挑战,包括关于减药临床益处的可用数据有限,以及在如何减药方面缺乏共识。当前的叙述性综述探讨了以虚弱作为决定减药的依据。对有关为体弱的老年人开具的用于常见心血管疾病(包括阿司匹林、他汀类药物和抗高血压药物)的药物使用益处的证据进行了综述。该综述还研究了应由谁启动减药过程的问题以及相关的心理影响。尽管不存在适用于所有情况的减药方法,但应优先考虑患者目标。对于体弱的老年人,医疗保健专业人员必须仔细考虑使用心血管药物的益处是否超过潜在危害。理想情况下,减药过程应涉及医生、其他卫生专业人员以及患者和/或其替代决策者之间的共同决策,其共同目标是改善患者的治疗效果。
