Frailty tends to be considered as a major risk for adverse outcomes in older persons, but some important aspects remain matter of debate.
The purpose of this paper is to present expert's positions on the main aspects of the frailty syndrome in the older persons.
Workshop organized by International Association of Gerontology and Geriatrics (IAGG), World Health Organization (WHO) and Société Française de Gériatrie et de Gérontologie (SFGG).
Frailty is widely recognized as an important risk factor for adverse health outcomes in older persons. This can be of particular value in evaluating non-disabled older persons with chronic diseases but today no operational definition has been established. Nutritional status, mobility, activity, strength, endurance, cognition, and mood have been proposed as markers of frailty. Another approach calculates a multidimensional score ranging from "very fit" to "severely frail", but it is difficult to apply into the medical practice. Frailty appears to be secondary to multiple conditions using multiple pathways leading to a vulnerability to a stressor. Biological (inflammation, loss of hormones), clinical (sarcopenia, osteoporosis etc.), as well as social factors (isolation, financial situation) are involved in the vulnerability process. In clinical practice, detection of frailty is of major interest in oncology because of the high prevalence of cancer in older persons and the bad tolerance of the drug therapies. Presence of frailty should also be taken into account in the definition of the cardiovascular risks in the older population. The experts of the workshop have listed the points reached an agreement and those must to be a priority for improving understanding and use of frailty syndrome in practice.
Frailty in older adults is a syndrome corresponding to a vulnerability to a stressor. Diagnostic tools have been developed but none can integrate at the same time the large spectrum of factors and the simplicity asked by the clinical practice. An agreement with an international common definition is necessary to develop screening and to reduce the morbidity in older persons.
虚弱倾向于被认为是老年人不良结局的主要风险因素,但一些重要方面仍存在争议。
本文旨在介绍专家对老年人虚弱综合征主要方面的看法。
国际老年学和老年医学协会(IAGG)、世界卫生组织(WHO)和法国老年医学和老年学学会(SFGG)组织的研讨会。
虚弱被广泛认为是老年人不良健康结局的重要危险因素。这在评估患有慢性疾病但无残疾的老年人时特别有价值,但目前尚未确定操作性定义。营养状况、移动能力、活动能力、力量、耐力、认知和情绪已被提议作为虚弱的标志物。另一种方法是计算一个多维评分,范围从“非常健康”到“严重虚弱”,但在医学实践中很难应用。虚弱似乎是多种条件通过多种途径导致对压力源的脆弱性的结果。生物(炎症、激素丧失)、临床(肌肉减少症、骨质疏松症等)以及社会因素(隔离、财务状况)都参与了脆弱性过程。在临床实践中,由于老年人癌症的高发和药物治疗的耐受性差,虚弱在肿瘤学中的检测具有重要意义。在老年人群中,心血管风险的定义也应考虑到虚弱的存在。研讨会的专家列出了达成一致的要点和必须优先考虑的要点,以提高对虚弱综合征的理解和在实践中的应用。
老年人虚弱是一种对应激源脆弱性的综合征。已经开发出了诊断工具,但没有一种工具能够同时整合广泛的因素和临床实践所要求的简单性。需要达成国际通用定义的协议,以开展筛查并减少老年人的发病率。
