Pediatric deep brain stimulation (pDBS) is commonly used to manage treatment-resistant primary dystonias with favorable results and more frequently used for secondary dystonia to improve quality of life. There has been little systematic empirical neuroethics research to identify ethical challenges and potential solutions to ensure responsible use of DBS in pediatric populations.
Clinicians (n = 29) who care for minors with treatment-resistant dystonia were interviewed for their perspectives on the most pressing ethical issues in pDBS.
Using thematic content analysis to explore salient themes, clinicians identified four pressing concerns: (1) uncertainty about risks and benefits of pDBS (22/29; 72%) that poses a challenge to informed decision-making; (2) ethically navigating decision-making roles (15/29; 52%), including how best to integrate perspectives from diverse stakeholders (patient, caregiver, clinician) and how to manage surrogate decisions on behalf of pediatric patients with limited capacity to make autonomous decisions; (3) information scarcity effects on informed consent and decision quality (15/29; 52%) in the context of patient and caregivers' expectations for treatment; and (4) narrow regulatory status and access (7/29; 24%) such as the lack of FDA-approved indications that contribute to decision-making uncertainty and liability and potentially limit access to DBS among patients who may benefit from it.
These results suggest that clinicians are primarily concerned about ethical limitations of making difficult decisions in the absence of informational, regulatory, and financial supports. We discuss two solutions already underway, including supported decision-making to address uncertainty and further data sharing to enhance clinical knowledge and discovery.
儿科脑深部电刺激(pDBS)常用于治疗耐药性原发性肌张力障碍,疗效良好,且越来越常用于继发性肌张力障碍,以改善生活质量。针对确保 DBS 在儿科人群中负责任地使用,已开展的系统经验神经伦理学研究很少,以确定伦理挑战和潜在解决方案。
我们对 29 名照顾耐药性肌张力障碍未成年人的临床医生进行了采访,以了解他们对 pDBS 中最紧迫的伦理问题的看法。
使用主题内容分析来探索突出的主题,临床医生确定了四个紧迫的关注点:(1)pDBS 的风险和益处的不确定性(22/29;72%),这对知情决策构成挑战;(2)在决策角色方面的伦理问题(15/29;52%),包括如何最好地整合来自不同利益相关者(患者、照顾者、临床医生)的观点,以及如何在代表无能力做出自主决策的未成年患者做出代理决策;(3)知情同意和决策质量方面的信息匮乏效应(15/29;52%),这在患者和照顾者对治疗的期望背景下产生;(4)监管地位和获取渠道狭窄(7/29;24%),例如缺乏 FDA 批准的适应症,这导致决策不确定性和责任,并可能限制可能从中受益的患者获得 DBS。
这些结果表明,临床医生主要关注在缺乏信息、监管和财务支持的情况下做出艰难决策的伦理限制。我们讨论了两种已经在进行的解决方案,包括支持决策以解决不确定性,以及进一步的数据共享以增强临床知识和发现。
