Real-world assessment of caregiver preference and compliance to treatment with twice-weekly versus daily rivastigmine patches in Alzheimer's disease.

BACKGROUND: Adherence is critical in patients with Alzheimer's disease (AD) in order to achieve optimal benefit from therapy. However, patient compliance with the treatment remains a challenge. OBJECTIVE: To evaluate, in a real-world clinical setting, caregiver preference and treatment compliance with twice-weekly versus daily transdermal rivastigmine patch in mild-to-moderate AD. METHODS: 92 patients who had been treated with daily rivastigmine patch for at least six months prior to switching to twice-weekly patch were evaluated. The change in therapeutic regimen was decided by the treating physician in accordance with standard practice. Caregivers' satisfaction with daily rivastigmine patch was assessed at study entry. Caregiver's preference and satisfaction with twice-weekly patch as well as patient compliance were evaluated at weeks 12 and 24 using the Alzheimer's Disease Caregiver Preference Questionnaire. RESULTS: A significantly higher proportion of caregivers expressed a preference for the twice-weekly patch over the daily patch (p < 0.001), and this preference was found to be associated with ease of use (p < 0.001), ease of following the schedule (p < 0.001), and ease of compliance (p < 0.001). Furthermore, caregivers were more satisfied with the twice-weekly patch (p < 0.0001). At 24 weeks, patient compliance was significantly better with the twice-weekly patch than with the daily patch (p = 0.002). Caregiver burden significantly improved at the end of the treatment (p = 0.003). No serious adverse events were reported. CONCLUSIONS: The twice-weekly rivastigmine patch offers a convenient and straightforward dosing regimen for caregivers, with potential to enhance adherence with treatment in AD patients without causing serious adverse events.

Effects of COVID-19 Lockdown on Nutritional, Functional and Frailty Biomarkers of People Living in Nursing Homes. A Prospective Study.

BACKGROUND: Nursing home residences suffered a lockdown from the beginning of the COVID-19 pandemic. The present study prospectively evaluates the frailty, functional, and nutritional statuses of nursing home residents. METHODS: Three hundred and one residents from three nursing homes took part in the study. Frailty status was measured using the FRAIL scale. Functional status was evaluated using the Barthel Index. Additionally, Short Physical Performance Batter (SPPB), SARC-F, hand-grip strength, and gait speed were also evaluated. Nutritional status was determined using the mini nutritional assessment test (MNA) and several anthropometrical and biochemical markers. RESULTS: Mini Nutritional Assessment test scores decreased in 20% throughout the confinement (p < .001). Barthel index, SPPB and SARC-F scores also decreased, although to a lesser extent, reflecting a decrease in functional capacity. However, both anthropometric parameters, hand grip strength and gait speed, remained stable throughout confinement (p > .050 in all cases). Morning cortisol secretion significantly decreased by 40% from baseline to post-confinement. A significant reduction in daily cortisol variability was observed, which may suggest increased distress. Fifty-six residents died during the period of confinement (81.4% survival rate). Sex, FRAIL and Barthel Index scores were significant predictors of resident survival. CONCLUSION: After the first COVID-19 blockade, several alterations in residents' frailty markers were observed, which were small and potentially reversible. However, many of the residents were pre-frail after the lockdown. This fact highlights the need for preventive strategies to reduce the impact of future social and physical stressors on these vulnerable individuals.

Evolution of antibody profiles against SARS-CoV-2 in experienced and naïve vaccinated elderly people.

Introduction: The third dose of the COVID-19 vaccine is especially necessary in people over 65 years of age due to their lower immune response. Methods: We designed a multicentre, prospective observational study including 98 people ≤65 years old who lived in two nursing homes in Valladolid, Spain. One of the groups had previous experience with SARS-CoV-2 (n=68;69.4%) and the other was naïve (n=30;30.6%). We evaluated the response to the three doses of the Comirnaty vaccine and the dynamics of antibodies during 5 consecutive serum samplings: 2 after the first two doses of vaccination, one three months after the first dose, another at 6 months and the last one month after the third dose. IgG antibodies against SARS-CoV-2 S1, RBD and N antigens were analysed. Results: Both groups increased the level of Abs against S1 and RBD, but the experienced group showed a 130-fold higher humoral response due to hybrid immunisation (infection+vaccination). The response to vaccination with Comirnaty against COVID-19 was higher in those ≤65 years with previous experience than those who were naïve. However, the amount of antibodies against S1 and RBD equalised at 6 months. After the third dose, both groups raised the amount of antibodies to a similar level. The reinfections suggested by the analysis of antibodies against N were frequent in both groups. Discussion: The third dose showed a clear benefit for elderly people, with the reinforcement of the antibody levels after the decline suffered after six months of the first two doses.

The Quality Index for Nutrition in Nursing Homes (QUINN). A new tool for evaluating diet quality in long-term care homes.

Introduction: Background: the assessment of diet quality (DQ) is fundamental to the study of disease-diet associations, and it is necesary to implement an easy to-apply tool in nursing homes (NHs). Our objective was to propose and apply a novel diet quality indicator (DQIn) using an a priori approach for NHs. Methods: the QUality Index for Nutrition in Nursing homes (QUINN) was implemented in a public NH located in Valladolid, Spain, during a 5-week period (n = 137 subjects). The choice of the QUINN components was based on a rapid review. The QUINN was based on 15 dietary components - 12 were basic (vegetables, fruits, legumes, olive oil, cereals, dairy, white fish and seafood, white-meat, eggs/positive; other fats, red and processed meat, and sweets/negative), and 3 were supplementary (fruits and vegetables variety, oily-fish, and whole-grains/positive). Each component was classified into 4-categories (0, 1, 2 o 3 points; range: 0-45 points). Results: the QUINN was tested on a menu offered by a NH giving a result of 34 points (good diet). The components with the highest scores were related to the Mediterranean diet (high consumption of legumes, olive oil, white fish and shellfish; low intake of other fats; and a wide variety of fruits and vegetables), together with cereals, white meat, dairy, and eggs. The components that required a major change were red- and processed-meats, sweets, and whole grains. Conclusion: the menu of this Spanish NH showed a good DQ according to the QUINN. The assessment of the DQ in NHs using QUINN will allow the proposal of interventions aimed at improving their diet.

Introducción: Antecedentes: la valoración de la calidad de la dieta es fundamental para el estudio de las asociaciones enfermedad-dieta, y es necesario implantar una herramienta de fácil aplicación en las residencias de ancianos. Nuestro objetivo fue proponer y aplicar un nuevo indicador de calidad de la dieta (diet quality indicator, DQIn) utilizando un enfoque a priori para su utilización en residencias de ancianos. Métodos: el Índice de Calidad Nutricional en Residencias de Ancianos (QUality Index for Nutrition in Nursing homes, QUINN) se aplicó en una residencia pública de Valladolid durante un periodo de 5 semanas (n = 137 sujetos). La elección de los componentes del QUINN se basó en una revisión rápida. En el QUINN se consideraron 15 componentes dietéticos, 12 básicos (verduras, frutas, legumbres, aceite de oliva, cereales, lácteos, pescado blanco y marisco, carnes blancas, huevos/positivos; otras grasas, carnes rojas y procesadas, y dulces/negativos) y 3 adicionales (variedad de frutas y verduras, pescado azul, y cereales integrales/positivos). Cada componente se clasificó en 4 categorías (0, 1, 2 o 3 puntos; rango: 0-45 puntos). Resultados: el QUINN se aplicó en el menú ofertado por una residencia de ancianos dando un resultado de 34 puntos (dieta de buena calidad). Los componentes con mayor puntuación estaban relacionados con la dieta mediterránea (alto consumo de legumbres, aceite de oliva, pescado blanco y marisco, bajo consumo de otras grasas y variedad de frutas y verduras), junto con los cereales, las carnes blancas, los lácteos y los huevos. Los componentes que requerían un cambio importante fueron las carnes rojas y procesadas, los dulces y los cereales integrales. Conclusión: el menú de esta residencia de ancianos situada en España mostró una calidad de la dieta buena según el QUINN. La evaluación de la calidad de la dieta en las residencias de ancianos mediante el QUINN permitirá proponer intervenciones para mejorar la dieta.

[Prevalence of dementia in institutionalized patients. The RESYDEM study]. / Prevalencia de demencia en pacientes institucionalizados: estudio RESYDEM.

INTRODUCTION: To determine the prevalence of dementia in nursing homes in Spain and to analyze the associated factors in an elderly population in the institutional setting. MATERIAL AND METHODS: We performed a multicenter, cross-sectional, observational study of 852 residents of public, private and state-assisted nursing homes throughout Spain. Dementia was diagnosed according to the DSM-IV-TR clinical criteria. The Hughes Clinical Dementia Rating scale was used to measure global impairment or the global severity of dementia. Sociodemographic, clinical and neuropsychological variables, together with the pharmacological treatments prescribed to the participants, were recorded. RESULTS: The overall prevalence of dementia was 61.7% (95% CI 58.4-65.1) and that of Alzheimer's disease was 16.9% (95% CI 14.3-19.5). Vascular dementia was found in 7.3% (95% CI 5.5-9.1). Female sex was independently associated with a greater frequency of dementia. The prevalence of dementia increased with age. Only 18.8% (95% CI 15.4-22.3) of the patients diagnosed with dementia received specific treatment for the disorder. CONCLUSIONS: Two-thirds of the elderly persons living in nursing homes in Spain have dementia. Undertreatment of this disease is common. Increased awareness among health care professionals is important for the early diagnosis and appropriate management of dementia, which would represent a radical change in the approach to this disease.

[Seasonal flu vaccination for older people: Evaluation of the quadrivalent vaccine. Positioning report]. / Vacunación frente a la gripe estacional en las personas mayores. Evaluación de la vacuna tetravalente. Informe de posicionamiento.

Influenza is a significant health problem, particularly in those persons susceptible to having associated complications, older people, children less than 2 years, patients with chronic diseases, immunocompromised patients, and pregnant women. But influenza also has a large impact on the health system, with an increase in the healthcare demand and a spectacular increase in outpatient visits, overloading the emergency and hospital services. During epidemic outbreaks, the hospital admission rates of people over 65 years are at a maximum, and the mortality notified for the 2017/2018 influenza season was 960 deaths. The seasonal anti-influenza vaccine is the method with a better cost-effective ratio of primary prevention of influenza, reducing associated respiratory diseases, the number of hospital admissions, and deaths in high risk individuals, as well as work absenteeism in adults. In the last few years, influenza B has received little attention in the scientific literature, although in the periods between epidemics influenza B can be one of the main causes of seasonal epidemics, causing considerable morbidity and mortality and an increase in costs. The quadrivalent vaccine has a second-line immunological protection against influenza B, and according to a critical review of the scientific literature, it provides wider protection without affecting immunogenicity of the other three vaccine strains common to the trivalent and tetravalent vaccine. The quadrivalent vaccine is cost-effective in reducing the number of influenza cases, and is always a worthwhile intervention, with a significant cost saving for the health system and for society, by reducing the hospital admission rates and mortality associated with the complications of influenza. Supplement information: This article is part of a supplement entitled 'Seasonal flu vaccination for older people: Evaluation of the quadrivalent vaccine' which is sponsored by Sanofi-Aventis, S.A.

Delphi consensus of an expert committee in oncogeriatrics regarding comprehensive geriatric assessment in seniors with cancer in Spain.

OBJECTIVES: The aim of this work was to reach a national consensus in Spain regarding the Comprehensive Geriatric Assessment (CGA) domains in older oncological patients and the CGA scales to be used as a foundation for widespread use. MATERIAL AND METHODS: The Delphi method was implemented to attain consensus. Representatives of the panel were chosen from among the members of the Oncogeriatric Working Group of the Spanish Society of Medical Oncology (SEOM). Consensus was defined as ≥66.7% coincidence in responses and by the stability of said coincidence (changes ≤15% between rounds). The study was conducted between July and December 2016. RESULTS: Of the 17 people invited to participate, 16 agreed. The panel concluded by consensus that the following domains should be included in the CGA:(and the scales to evaluate them): functional (Barthel Index, Lawton-Brody scale, gait speed), cognitive (Pfeiffer questionnaire), nutritional (Mini Nutritional Assessment - MNA), psychological/mood (Yesavage scale), social-familial (Gijon scale), comorbidity (Charlson index), medications, and geriatric syndromes (urinary and/or fecal incontinence, low auditory and/or visual acuity, presence of falls, pressure sores, insomnia, and abuse). Also by consensus, the CGA should be administered to older patients with cancer for whom there is a subsequent therapeutic intent and who scored positive on a previous frailty-screening questionnaire. CONCLUSION: After 3 rounds, consensus was reached regarding CGA domains to be used in older patients with cancer, the scales to be administered for each of these domains, as well as the timeline to be followed during consultation.

[Cognitive impairment/dementia: assessment and follow-up. Functional aspects]. / Deterioro cognitivo/demencia: valoración y seguimiento. Aspectos funcionales.

The importance of functional status is increasingly being recognized in current clinical management. This is especially important in mild cognitive impairment (MCI), which is a priority due to its direct relationship with dementia and awareness that functional alterations are what separates MCI from dementia. Adequate assessment of MCI during the follow-up of this condition allows identification of its progress, whether towards normal cognitive function or detection and diagnosis of the incipient stages of dementia, thus providing the benefits of early diagnosis. This article describes assessment tools for this condition, beginning with performance tests as an objective measure of mobility, followed by measurement of activities of daily living (ADL): advanced, instrumental and basic, with emphasis on the Sydney Test of Activities of Daily Living in Memory Disorders (STAM) and Mongil's tests of activities of daily living. Patient follow-up is essential and should combine assessment of performance tests and ADL measurement. Emphasis is placed on functional status not only because of its association with MCI but also because it has become a therapeutic target and an outcomes indicator.

[Seasonal flu vaccination for older people: Evaluation of the adjuvanted vaccine. Positioning report]. / Vacunación frente a la gripe estacional en las personas mayores. Evaluación de la vacuna adyuvada: Informe de posicionamiento.

Flu is a major public health problem, particularly for older people, and creates an important clinical and economic burden. A high mortality rate was reported in Spain during the period 2015 to 2016; 3,101 serious cases were hospitalised with a confirmed diagnosis of flu, of which 11% died (352 cases). Furthermore, financial and health costs are greatly increased by the complications of flu; people aged over 65 years represent approximately 64% of the total costs. Seasonal flu vaccination is the fundamental strategy, as demonstrated by cost-benefit and cost-effectiveness studies. A priority objective is to improve the vaccine's immune response and the search for and inclusion of adjuvants and immunostimulants in vaccines is a major line of research. This positioning report evaluates vaccination for older people and the importance of the adjuvanted vaccine in the elderly in strengthening immunogenicity, by means of a critical review of the literature based on the best evidence available on its immunogenicity and effectiveness, and an economic assessment.

[Prognosis and progression of cognitive impairment. Preventive measures]. / Pronóstico y proceso evolutivo del deterioro cognitivo. Medidas preventivas.

Because of the substantial increase in population ageing, age-related processes, such as dementia and Alzheimer disease (AD), are becoming highly prevalent. The course of this disease, including preprodromic phases, lasts at least 20 years. The presence of comorbidities, especially those of vascular origin, can trigger and aggravate disease progression. On the other hand, cognitive reserve, the absence or control of comorbid factors and healthy lifestyles can protect or modify -in the sense of slow down- disease progression. Knowledge of the phases of AD and their functional impact on affected individuals helps to identify the average prognosis and, in particular, to establish and predict care plans based on the individual's needs.

[Nutritional status assessment in Geriatrics: Consensus declaration by the Spanish Society of Geriatrics and Gerontology NutritionWork Group]. / Valoración del estado nutricional en Geriatría: declaración de consenso del Grupo de Nutrición de la Sociedad Española de Geriatría y Gerontología.

Ongoing population ageing is one of the factors influencing the increase in the prevalence of undernutrition, as elderly people are a vulnerable group due to their biological, psychological and social characteristics. Despite its high prevalence, undernutrition is underdiagnosed in the geriatric sphere. For this reason, the aim of this consensus document is to devise a protocol for geriatric nutritional assessment. A multidisciplinary team has been set up within the Spanish Society of Geriatrics and Gerontology (in Spanish Sociedad Española de Geriatría y Gerontología [SEGG]) in order to address undernutrition and risk of undernutrition so that they can be diagnosed and treated in an effective manner. The MNA-SF is a practical tool amongst the many validated methods for nutritional screening. Following suspicion of undernutrition, or after establishing the presence of undernutrition, a full assessment will include a detailed nutritional history of the patient. The compilation of clinical-nutritional and dietetic histories is intended to help in identifying the possible risk factors at the root of a patient's undernutrition. Following this, an anthropometric assessment, combined with laboratory data, will describe the patient's physical and metabolic changes associated to undernutrition. Currently, the tendency is for further nutritional assessment through the use of non-invasive techniques to study body composition in association with functional status. The latter is an indirect index for nutritional status, which is very interesting from a geriatrician's point of view. To conclude, correct nutritional screening is the fundamental basis for an early undernutrition diagnosis and to assess the need for nutritional treatment. In order to achieve this, it is fundamental to foster research in the field of nutritional geriatrics, in order to expand our knowledge base and to increasingly practice evidence-based geriatrics.

La gripe es un importante problema de salud pública, particularmente en las personas susceptibles de presentar complicaciones asociadas, personas mayores, niños menores de 2 años, enfermos crónicos, inmunocomprometidos y embarazadas. Pero, además, la gripe tiene un gran impacto sanitario con un aumento de la demanda asistencial y un espectacular aumento de las visitas ambulatorias, sobrecargando los servicios de urgencias y hospitalarios. Durante los brotes epidémicos, las tasas de hospitalización de las personas mayores de 65 años son máximas y la mortalidad notificada por gripe en la temporada 2017/2018 ha sido de 960 defunciones. La vacunación antigripal estacional es el método con una mayor relación coste-efectividad de prevención primaria de la gripe, reduciendo las enfermedades respiratorias relacionadas, el número de visitas a las consultas médicas, el número de hospitalizaciones y muertes en personas de alto riesgo y el absentismo laboral en adultos. En los últimos años la gripe B ha recibido escasa atención en la literatura científica y, sin embargo, en períodos interepidémicos, la gripe B puede ser una de las principales causas de epidemias de gripe estacional, causando una considerable morbimortalidad y un aumento de costes. La vacuna tetravalente, a diferencia de la trivalente, obtiene una protección inmunológica frente al segundo linaje de la gripe B y, de acuerdo con una revisión crítica de la literatura científica, proporciona una protección más amplia sin afectar a la inmunogenicidad de las otras 3 cepas vacunales comunes a las vacunas trivalente y tetravalente. La vacuna tetravalente es coste-efectiva al disminuir el número de casos de gripe y siempre es una intervención rentable, con un importante ahorro de coste para el sistema de salud y para la sociedad, disminuyendo las tasas de hospitalización y de mortalidad asociadas a las complicaciones de la gripe

Deterioro cognitivo/demencia: valoración y seguimiento. Aspectos funcionales / Cognitive impairment/dementia: assessment and follow-up. Functional aspects

Actualmente nos encontramos en un proceso de cambio en la gestión clínica, en el cual el estado funcional adquiere una relevancia que hasta ahora no se había considerado. Esto es especialmente importante en el deterioro cognitivo leve, entidad prioritaria por la relación directa con la demencia, y conociendo que son precisamente las alteraciones en la funcionalidad las características que separan el deterioro cognitivo leve de la demencia. Valorar adecuadamente el deterioro cognitivo leve durante el seguimiento de este permitirá conocer su evolución hacia la normalidad cognitiva o detectar y diagnosticar en estadios muy incipientes la demencia, con los beneficios que reporta el diagnóstico en estos estadios. Se presentan las herramientas para proceder a la valoración comenzando con los test de ejecución como medida objetiva de movilidad y seguidamente la medición de las actividades de la vida diaria: avanzadas, instrumentales y básicas, haciendo hincapié en el examen STAM (Sydney Test of Activities of Daily Living in Memory Disorders) y en los test Mongil. El seguimiento del paciente es fundamental, asociando en la valoración test de ejecución y medición de actividades de la vida diaria. El énfasis en el estado funcional no es solo por su relación con el deterioro cognitivo leve, es que pasa a ser un objetivo terapéutico y un indicador de resultado (AU)

La gripe es un importante problema de salud pública, particularmente en las personas mayores, con una significativa carga clínica y económica y con una alta mortalidad. En España, durante la temporada 2015- 2016, se han notificado 3.101 casos graves hospitalizados confirmados por gripe, de los que han fallecido el 11% (352 casos). Además, hay un gran aumento de costes económicos y sanitarios por sus complicaciones y los mayores de 65 años representan aproximadamente el 64% del total de costes de la gripe. La vacuna antigripal estacional es la estrategia fundamental, y los estudios de coste-beneficio y coste-efectividad así lo demuestran.

El importante auge de las tasas de envejecimiento poblacional lleva consigo que procesos vinculados a la longevidad, como el caso de la demencia y el caso particular de la enfermedad de Alzheimer, adquieran características de procesos altamente prevalentes. El proceso evolutivo de esta enfermedad, contando desde fases preprodrómicas, se sitúa, al menos, en una duración de 20 años. La presencia de comorbilidades, especialmente las de origen vascular, puede precipitar y empeorar el curso de la enfermedad. Por otro lado, la reserva cognitiva, la ausencia o control de los factores comórbidos y los estilos de vida saludable pueden proteger o modificar, en el sentido de enlentecer, la progresión de la enfermedad. Conocer las fases de la EA y el impacto funcional que en cada una de ellas padece la persona enferma ayuda a establecer pronósticos promedios y, sobre todo, a establecer y prever planes de cuidados sobre la base de las necesidades de la persona (AU)

Valoración del estado nutricional en Geriatría: declaración de consenso del Grupo de Nutrición de la Sociedad Española de Geriatría y Gerontología / Nutritional status assessment in Geriatrics: Consensus declaration by the Spanish Society of Geriatrics and Gerontology Nutrition Work Group

El progresivo envejecimiento de la población es uno de los factores que influyen en el aumento de la prevalencia de desnutrición, ya que los ancianos son un colectivo de riesgo por sus características biológicas, psicológicas y sociales. A pesar de su alta prevalencia, la desnutrición está infradiagnosticada en geriatría. Por este motivo, el objetivo del presente documento de consenso es elaborar un protocolo de valoración nutricional geriátrica. En el marco de la SEGG se ha creado un equipo multidisciplinar con el objetivo de darle la debida importancia a la desnutrición y el riesgo de la misma para que sean diagnosticadas y tratadas de forma adecuada. Entre los muchos métodos validados para el cribado nutricional, el MNA-SF representa una herramienta práctica. Tras evidenciar la sospecha o la presencia de desnutrición la valoración completa prevé la realización de una historia nutricional exhaustiva. Las historias clínico-nutricional y dietética pretenden evidenciar los posibles factores de riesgo sobre la base del cuadro de desnutrición. Entonces la valoración antropométrica, asociada a los datos de laboratorio, pretende objetivar las modificaciones físicas y metabólicas asociadas a la desnutrición. Hoy en día cada vez más se tiende a profundizar en la valoración nutricional utilizando técnicas no invasivas de estudio de la composición corporal asociadas al estudio funcional. Esta última representa un índice indirecto del estado nutricional de gran interés para la geriatría. En conclusión, un correcto cribado nutricional es la base fundamental para un temprano diagnóstico de desnutrición y poder valorar la indicación al tratamiento nutricional. Para esto es fundamental fomentar la investigación en el campo de la nutrición geriátrica para aumentar el conocimiento y poder hacer cada vez más una geriatría basada en la evidencia (AU)

Residencias pertenecientes a todas las Comunidades Autónomas del Estado español de titularidad pública, privada y concertada. Se incluyó a un total de 852 ancianos institucionalizados, participantes en el estudio RESYDEM.El diagnóstico de demencia se estableció sobre la base de los criterios clínicos del DSM-IV-TR. Como medida del deterioro global o valoración global de la gravedad de la demencia se utilizó la escala Clinical Dementia Rating (CDR) de Hughes. Se recogieron variables sobre características clínicas y sociodemográficas, y los tratamientos farmacológicos de los participantes.Resultadosla prevalencia global de demencia hallada en este estudio fue del 61,7% (intervalo de confianza [IC] del 95%, 58,4–65,1). La enfermedad de Alzheimer se presentó con una prevalencia del 16,9% (IC del 95%, 14,3–19,5). La demencia vascular supone el 7,3% (IC del 95%, 5,5–9,1). El género femenino se asoció de forma independiente con una mayor frecuencia de demencia. Se evidenció una mayor prevalencia de esta afección a medida que aumentaba la edad. Sólo el 18,8% (IC del 95%, 15,4–22,3) de los pacientes con diagnóstico de demencia reciben tratamiento específico para ésta.Conclusionesdos terceras partes de las personas mayores que viven en residencias de ancianos en España presentan demencia. Existe una elevada tasa de infratratamiento de este proceso. Es importante la sensibilización de los profesionales sanitarios para la identificación precoz y para conocer la existencia de tratamientos específicos para la demencia, lo cual debe suponer un cambio radical en el abordaje de la enfermedad (AU)

IntroductionTo determine the prevalence of dementia in nursing homes in Spain and to analyze the associated factors in an elderly population in the institutional setting.Material and methodsWe performed a multicenter, cross-sectional, observational study of 852 residents of public, private and state-assisted nursing homes throughout Spain. Dementia was diagnosed according to the DSM-IV-TR clinical criteria. The Hughes Clinical Dementia Rating scale was used to measure global impairment or the global severity of dementia. Sociodemographic, clinical and neuropsychological variables, together with the pharmacological treatments prescribed to the participants, were recorded.ResultsThe overall prevalence of dementia was 61.7% (95% CI 58.4–65.1) and that of Alzheimer's disease was 16.9% (95% CI 14.3–19.5). Vascular dementia was found in 7.3% (95% CI 5.5–9.1). Female sex was independently associated with a greater frequency of dementia. The prevalence of dementia increased with age. Only 18.8% (95% CI 15.4–22.3) of the patients diagnosed with dementia received specific treatment for the disorder.ConclusionsTwo-thirds of the elderly persons living in nursing homes in Spain have dementia. Undertreatment of this disease is common. Increased awareness among health care professionals is important for the early diagnosis and appropriate management of dementia, which would represent a radical change in the approach to this disease (AU)
