Heterogeneidad en el cribado poblacional de la fragilidad / Heterogeneity amongst different diagnostic tools in frailty screening

Fundamento: La fragilidad supone una situación de vulnerabilidad predisponente a resultados adversos en salud, relacionada con la edad y la pérdida de capacidad funcional. Aunque Atención Primaria (AP) es un nivel asistencial privilegiado para detectarla precozmente e instaurar medidas que frenen su progresión, no existe una herramienta gold standard para su detección. El objetivo es analizar la prevalencia de fragilidad en AP y evidenciar la herramienta diagnóstica más útil para este medio. Materialy métodos: Estudio transversal realizado en una muestra de 225 personas seleccionadas aleatoriamente de una población de 4.252 mayores de 75 años de tres zonas de Navarra. Se realizaron cuatro pruebas diagnósticas de fragilidad: el fenotipo de Fried, el Short Physical Performance Battery (SPPB), el Up-to Go (TUG) y el de la velocidad de la marcha (VM). Los participantes que no consiguieron finalizar alguna de las pruebas no fueron considerados en el análisis posterior. Resultados: El 51% de los participantes eran hombres, con edad media de 80,5 años, el 80% polimedicados, el 8,4% con deterioro cognitivo y el 31,1 y el 41,3% independientes para las actividades básicas e instrumentales, respectivamente, de la vida diaria. La prevalencia de fragilidad fue 8,4% (Fried), 13,7% (SPPB), 46,2% (TUG) y 52,2% (VM). Conclusiones. Se detectó gran heterogeneidad en la prevalencia de fragilidad según la herramienta diagnóstica empleada. Es necesaria una herramienta fiable, rápida y sencilla para la detección precoz de la fragilidad en AP por lo que, según los resultados y las peculiaridades de AP, proponemos el TUG o la VM como buenos predictores precoces de este deterioro

Background: Frailty means a state of vulnerability with a predisposition to adverse health outcomes, closely related to age and a consequent loss of functional capability. Early detection is important for initiating measures to slow its progression. Primary Health Care (PHC) occupies a privileged place in this. However, we do not possess a gold standard tool for its detection. Our aim is to analyse the prevalence of frailty in PHC and define the most useful diagnostic tool for this area. Methods: Cross-sectional study with 225 people were selected from a population of 4,252 people aged over 75 years-old, from three different basic health zones of Navarre. Four different diagnostic tests for frailty were conducted: the Fried phenotype, the Short Physical Performance Battery (SPPB), the Timed Up-to-Go test (TUG) and the Gait Speed test (GS). Patients who were unable to finish any of the tests weren't included in the subsequent analysis. Results: Fifty-one percent of participants were men, with mean age 80.5 years-old, 80% were taking more than five daily drugs, 8.4% had cognitive impairment, and 31.1 and 41.3% were independent for basic and instrumental activities, respectively, of daily living. The frailty prevalence was 8.3% for Fried phenotype, 13.7% for SPPB, 46.2% for TUG and 52.2% for Gait Speed. Conclusion: Great heterogeneity in the prevalence of frailty was shown depending on the tool employed. As a reliable, fast and simple tool for early detection of frailty is needed in PHC, based on our results and the particularities of PHC, we propose TUG or GS as good early predictors of this decline

The relationship between frailty and polypharmacy in older people: A systematic review.

AIMS: Frailty is a complex geriatric syndrome resulting in decreased physiological reserves. Frailty and polypharmacy are common in older adults and the focus of extensive studies, although little is known about the impact they may have on each other. This is the first systematic review analysing the available evidence on the relationship between frailty and polypharmacy in older adults. METHODS: Systematic review of quantitative studies. A comprehensive literature search for publications in English or Spanish was performed on MEDLINE, CINAHL, the Cochrane Database and PsycINFO in September 2017 without applying restrictions on the date of publication. Studies reporting any relationship between frailty and polypharmacy in older adults were considered. RESULTS: A total of 25 publications were included, all of them observational studies. Evaluation of Fried's frailty criteria was the most common approach, followed by the Edmonton Frail Scale and FRAIL scale. Sixteen of 18 cross-sectional analyses and five of seven longitudinal analyses demonstrated a significant association between an increased number of medications and frailty. The causal relationship is unclear and appears to be bidirectional. Our analysis of published data suggests that polypharmacy could be a major contributor to the development of frailty. CONCLUSIONS: A reduction of polypharmacy could be a cautious strategy to prevent and manage frailty. Further research is needed to confirm the possible benefits of reducing polypharmacy in the development, reversion or delay of frailty.

Physical Activity and Early Rehabilitation in Hospitalized Elderly Medical Patients: Systematic Review of Randomized Clinical Trials.

BACKGROUND: To critically review the effect of interventions incorporating exercise and early rehabilitation (physical therapy, occupational therapy, and physical activity) in the functional outcomes (i.e., active daily living tests, such as Barthel Index Scores, Timed-up-and go, mobility tests), and feasibility in hospitalized elderly medical patients. DESIGN: Systematic review of the literature. METHODS: A literature search was conducted using the following databases and medical resources from 1966 to January 2014: PubMed (Medline), PEDro, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews, Google Scholar, ClinicalTrials.gov, Clinical Evidence, SportsDiscus, EMBASE and UptoDate. Studies must have mentioned the effects of early rehabilitation on the above mentioned functional outcomes and feasibility. Data on the mortality, economic profile and average stay were also described. RESULTS: From the 6564 manuscripts potentially related to exercise performance in hospitalized elderly patients, the review focused on 1086, and 17 articles were ultimately included. Regarding functional outcomes after discharge, four studies observed significant improvement in functional outcomes following early rehabilitation, even up to twelve months after discharge. Eight studies directly or indirectly assessed the economic impact of exercise intervention. Five of them did not show any increase in costs, while three concluded that the intervention was cost effective. No adverse effect related with the interventions were mentioned. CONCLUSION: The introduction of an exercise program for hospitalized elderly patients may be feasible, and may not increase costs. Importantly, early rehabilitation may also improve the functional and healthcare.

[Physical exercise as an efficient intervention in frail elderly persons]. / Ejercicio físico como intervención eficaz en el anciano frágil.

Frailty is a state of vulnerability that involves an increased risk of adverse events in older adults. It is a condition with a complex etiology and pathophysiology. At present, there are functional tools for its assessment that are simple and reliable. Physical inactivity is a major risk factor for sarcopenia, a core aspect of frailty. Currently, multicomponent exercise programs, and especially resistance exercise, are the most relevant interventions to slow down disability and other adverse outcomes. Moreover, these programs are valuable interventions in other frailty domains such as falls, cognitive decline and depression. However, in frail aged patients it is necessary to explore optimal resistance training components and develop specific clinical guides of physical activity for this target population.

Ejercicio físico como intervención eficaz en el anciano frágil / Physical exercise as an efficient intervention in frail elderly persons

El síndrome de la fragilidad define a los ancianos vulnerables que tienen un riesgo elevado de sufrir eventos adversos. Su fisiopatología y etiopatogenia es compleja, pero actualmente disponemos de medidas sencillas de capacidad funcional para su evaluación. La inactividad física, que frecuentemente asocia el envejecimiento, es uno de los factores fundamentales que contribuye a la aparición de sarcopenia, aspecto central de la fragilidad. Los programas de ejercicio físico multicomponente y, particularmente el entrenamiento de la fuerza, constituyen las intervenciones más eficaces para retrasar la discapacidad y otros eventos adversos. Así mismo, han demostrado su utilidad en otros dominios frecuentemente asociados a este síndrome como las caídas, el deterioro cognitivo y la depresión. Sin embargo, es necesario investigar cuáles son los componentes óptimos de un programa de fuerza en el frágil, así como la óptima relación dosis-respuesta que permita desarrollar guías clínicas específicas de actividad física para este grupo poblacional(AU)
