Due to prognostic uncertainty and limited decision-making capacity, the choice to perform transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis (AS) and comorbid dementia is challenging. This study explores older adults' perspectives on complex decision-making preceding TAVI in the hypothetical setting of comorbid dementia.
Qualitative study entailing semistructured interviews. Analysis was by systematic text condensation. The interview guide addressed their attitudes regarding treatment dilemmas before TAVI in patients living with dementia.
Patients were recruited from the TAVI outpatient clinic at a university hospital performing TAVI.
A purposive sample of 10 older adults (5 women) with AS and without dementia (range 77-94 years), where 8/10 had undergone TAVI were included.
Three main challenges were identified: (1) Risk assessment. Participants found it hard to compare the burden of aortic stenosis vs dementia. They acknowledged the dilemma of implanting a new heart valve to achieve symptom relief while risking severe dementia in the future due to prolonged life span. (2) Autonomous capacity. A profound uncertainty was described regarding who should participate in decision-making if the person was incapacitated due to dementia. (3) Customised information. Participants advocated for thorough information describing facts and uncertainty, aiming to protect and support the person living with dementia.
Older adults with severe aortic stenosis find it hard relating to dilemmas arising from providing TAVI in patients living with dementia. There is a need for tailor-made information to support autonomy and decision-making under uncertainty.
由于预后不确定和决策能力有限,在患有严重主动脉瓣狭窄(AS)和合并痴呆的患者中选择进行经导管主动脉瓣植入术(TAVI)具有挑战性。本研究探讨了老年人在合并痴呆的假设情况下,在 TAVI 之前进行复杂决策的观点。
包括半结构化访谈的定性研究。分析采用系统文本冷凝。访谈指南涉及他们对痴呆患者 TAVI 前治疗困境的态度。
患者从一所大学医院的 TAVI 门诊病房招募。
纳入了 10 名患有 AS 且无痴呆的老年人(5 名女性)的随机样本(77-94 岁),其中 8/10 人已接受 TAVI。
确定了三个主要挑战:(1)风险评估。参与者发现比较主动脉瓣狭窄与痴呆的负担很困难。他们承认,植入新的心脏瓣膜以缓解症状的同时,由于预期寿命延长,将来可能会患上严重的痴呆症,这存在很大的风险。(2)自主能力。如果因痴呆而丧失能力,应该由谁参与决策,这方面存在很大的不确定性。(3)定制信息。参与者提倡提供全面的信息,描述事实和不确定性,旨在保护和支持患有痴呆症的人。
患有严重主动脉瓣狭窄的老年人发现很难处理在患有痴呆的患者中提供 TAVI 时出现的困境。需要定制信息,以支持在不确定情况下的自主权和决策。
