衰弱作为一种常见的老年综合征,以多系统功能障碍,体内平衡受损,生理储备下降,以及死亡风险增加为特点。心力衰竭(HF)是由各种心脏结构或功能性疾病导致心室充盈和(或)射血能力受损而引起的一组综合征,常常合并衰弱,与身体机能下降、跌倒、失能及认知倒退等相关。衰弱在老年心力衰竭患者中很常见,二者具有共同的机制特征,与炎症、肌肉减少症和高负担合并症等密切相关。衰弱与老年心力衰竭患者较差的临床表现、功能和生活质量有关,因此开发简单、易操作并经过充分验证的评估工具识别衰弱至关重要。这些评估工具可以在常规临床环境中有效和快速地识别衰弱的心衰患者,以更好地改善临床预后。对于患有心力衰竭和衰弱的老年患者,应进一步研究新的治疗与管理策略,例如通过多学科评估和干预解决多系统疾病的模式。提高对心力衰竭合并衰弱的认识并加以管理,以期有助于改善患者不良预后和生活质量的提高。 相似文献

As nonreplicative cells age, they commonly accumulate subcellular deficits that can compromise function. As people age, they too experience problems that can accumulate. As deficits (symptoms, signs, illnesses, disabilities) accumulate, people become more susceptible to adverse health outcomes, including worse health and even death. This state of increased risk of adverse health outcomes is indistinguishable from the idea of frailty, so deficit accumulation represents another way to define frailty. Counting deficits not only allows grades of frailty to be discerned but also provides insights into the complex problems of older adults. This process is potentially useful to geriatricians who need to be experts in managing complexity. A key to managing complexity is through instruments such as a comprehensive geriatric assessment, which can serve as the basis for routine clinical estimation of an individual's degree of frailty. Understanding people and their needs as deficits accumulate is an exciting challenge for clinical research on frailty and its management by geriatricians. 相似文献

Cardiovascular disease (CVD) is the leading cause of death in developed countries and disproportionately affects older adults. Frailty is a complex clinical syndrome with multiple causes and contributing factors in which there is increased vulnerability when exposed to a minor stressor and increased risk for adverse outcomes, such as disability, hospitalization and mortality. Frailty is an important prognostic factor in patients with CVD, and so identifying this feature when assessing these patients may help to individually tailor cardiovascular treatment. The first step is to identify frailty. Several tools have been validated as screening methods for frailty. However, they diverge with regard to complexity, nature, feasibility and the outcome they can predict. The aim of this review is to describe the available screening tools for frailty and to examine their usefulness in patients with CVD. 相似文献

Objective
To describe the current definitions, aetiology, assessment tools and clinical implications of frailty in modern surgical practice.Background
Frailty is a critical issue in modern surgical practice due to its association with adverse health events and poor post-operative outcomes. The global population is rapidly ageing resulting in more older patients presenting for surgery. With this, the number of frail patients presenting for surgery is also increasing. Despite the identification of frailty as a significant predictor of poor health outcomes, there is currently no consensus on how to define, measure and diagnose this important syndrome.Methods
Relevant references were identified through keyword searches of the Cochran, MEDLINE and EMbase databases.Results
Despite the lack of a gold standard operational definition, frailty can be conceptualised as a state of increased vulnerability resulting from a decline in physiological reserve and function across multiple organ systems, such that the ability to withstand stressors is impaired. Multiple studies have shown a strong association between frailty and adverse peri-operative outcomes. Frailty may be assessed using multiple tools; however, the ideal tool for use in a clinical setting has yet to be identified. Despite the association between frailty and adverse outcomes, few interventions have been shown to improve outcomes in these patients.Conclusion
Frailty encompasses a group of individuals at high risk of adverse post-operative outcomes. Further work exploring ways to optimally assess and target interventions towards these patients should be the focus of ongoing research.14.
ObjectivesFrailty is an increasingly common health condition and is seen more often due to the ageing population. This study reviews the evidence on the development and validation of these automated frailty measurement tools.DesignSix databases: PubMed, EMBASE, MEDLINE, CINAHL, Scopus, and Web of Science were electronically searched. Selected studies must have developed and validated a new frailty measurement tool using administrative health data and published results in a peer-reviewed, English-language journal. Selected studies were synthesized narratively.Setting and participantsThe review focused on large scale studies using administrative health data in developed countries. Participants included older people aged 65 years and above.MeasuresThe main measures of review studies include discrimination power and the prediction ability of adverse health outcomes; performance against established frailty measures; and validation records.ResultsFive studies were selected for narrative synthesis after screening the full-text. All frailty measurement tools in the selected five studies produced strong discrimination power with C-statistics ranging from 0.61−97. Two studies were independently validated in studies by other authors or conducted in other locations; one study developed an early prediction model, and no study has been applied in practice.Conclusions and implicationsAutomated frailty measurement tools using administrative health data are still in the early development stage with five tools developed since 2016. Selected studies have strong prediction of adverse health outcomes. Future studies should include validation and refinement of these tools in other countries and assessment of their clinical utility and capacity to inform cost-effective policy and practice. 相似文献

OBJECTIVES: To construct and validate a frailty index (FI) that is clinically sensible and practical for geriatricians by basing it on a routinely used comprehensive geriatric assessment (CGA) instrument. DESIGN: Secondary analysis of a 3-month randomized, controlled trial of a specialized mobile geriatric assessment team. SETTING: Rural Nova Scotia. Participants were seen in their homes. PARTICIPANTS: Frail older adults, of whom 92 were in the intervention group and 77 in the control group. MEASUREMENTS: A standard CGA form that accounts for impairment, disability, and comorbidity burden was scored and summed as a frailty index (FI-CGA). The FI-GCA was stratified to describe three levels of frailty. Patients were followed for up to 12 months to determine how well the index predicted adverse outcomes (institutionalization or mortality, whichever came first). RESULTS: The three levels of frailty were mild (FI-CGA 0-7), moderate (FI-CGA 7-13), and severe (FI-CGA>13). Demographic and social traits were similar across groups, but greater frailty was associated with worse function (r=0.55) and mental status (r=0.33). Those with moderate and severe frailty had a greater risk of adverse outcomes than those with mild frailty (unadjusted hazard ratio=1.9 and 5.5, respectively). There was no difference between frailty groups in mean 3-month goal-attainment scaling scores. Intrarater reliability was 0.95. CONCLUSION: The FI-CGA is a valid, reliable, and sensible clinical measure of frailty that permits risk stratification of future adverse outcomes. 相似文献

BackgroundSeveral frailty rating scales have been developed to detect and screen for the level of frailty. It is uncertain what diagnostic value screening of frailty level have in the emergency department.AimTo assess the accuracy of the screening tools used in the emergency department to detect frailty in patients ≥ 65 years by their ability to identify the risk of adverse outcomes.MethodsAn extensive medical literature search of Embase and PubMed was conducted, to identify studies using frailty screening scales in the emergency department. Data was subsequently extracted and evaluated from the results of the included studies.ResultsFour studies met the exact inclusion criteria. Four different frailty screening scales: Clinical Frailty Scale, Deficit Accumulation Index, Identification of Seniors At Risk and The Study of Osteoporotic Fracture frailty index used in the emergency department were described and compared. Predictive values for various outcomes are represented and discussed.ConclusionsThe results suggest that frailty successfully predicts increased risk of hospitalization, nursing home admission, mortality and prolonged length of stay after an initial emergency department visit. Frailty does however not predict increased risk of 30 day emergency department revisit. Further research highlighting the value of screening for frailty level in elderly emergency department patients is needed.Learning pointsAlthough frail elders in need of further geriatric assessment should be identified as soon as possible, this systematic review only identified four cohort studies of frailty assessment in emergency departments.Although frailty screening appeared to predict the risk of mortality and of admission to hospital/nursing home, these four studies did not show that it could predict return visits to emergency departments within 30 days.Randomized clinical trials of frailty screening tools compared to usual care or other methods of assessment are clearly needed. 相似文献
