RESUMO

Since 1948, the World Health Organization has been publishing the International Statistical Classification of Diseases and Related Health Problems (ICD), a coded system of causes of disease and death with an in-depth revision every 10-15 years. In its latest revision, the ICD-11 uses nomenclature characterizing old age as "initial and final geriatric periods," implying the medicalization of this stage of life, which has created confusion and sparked controversy. This article discusses the new nomenclature proposed, given the current knowledge about old age and the aging process and its most accepted definition. The ICD not only classifies diseases but periods of life and "health-related problems," and old age per se is not a health-related problem for many people at this stage of life. It is therefore essential to change or provide a more nuanced definition of the term "old age" in the ICD-11, so it is not perceived as a symptom, sign, or anomalous clinical outcome, and to introduce nomenclature that more accurately reflects pathological aging. Two terms that are enjoying growing experimental and bibliographic support are "fragility" and "loss of intrinsic capacity," which offer greater precision when defining the condition of a person who is not experiencing healthy aging.

RESUMO

[RESUMEN]. Desde 1948, la Organización Mundial de la Salud ha venido publicando un sistema codificado de causas de enfermedad y muerte bajo el nombre genérico de Clasificación Estadística Internacional de Enfermedades (CIE), con revisiones en profundidad cada 10-15 años. En su última versión, CIE-11, se utiliza una terminolo-gía para caracterizar la vejez como “períodos geriátricos inicial y final”, lo que implica una medicalización de esta etapa de la vida que ha generado confusión y polémica. En este trabajo se discute la nueva terminología propuesta a la luz del conocimiento actual en torno a la vejez y el proceso de envejecimiento, y su definición más aceptada. La CIE no solo clasifica las enfermedades sino también los períodos de la vida y los “proble-mas relacionados con la salud”, y la vejez por sí sola no representa un problema relacionado con la salud para muchos de quienes se encuentran en esta etapa de la vida. Desde esta perspectiva, es imprescindible cambiar o matizar el epígrafe “vejez” de la CIE-11 para que no se perciba como síntoma, signo o resultado clínico anómalo, e introducir términos que reflejen mucho mejor el estado de envejecimiento patológico. Entre los términos que gozan de un creciente soporte experimental y bibliográfico están “fragilidad” y “pérdida de la capacidad intrínseca”, que aportan mucha mayor precisión a la hora de definir la condición de la persona que no goza de un envejecimiento saludable.

RESUMO

BACKGROUND: Inappropriate medication use in older people is an important source of adverse events and complications. AIM: To determine the frequency of inappropriate medication use in the general population. MATERIAL AND METHODS: As part of the 2010 Chilean National Health Survey, 1,048 persons aged 65 years or more were interviewed about medication use. The information obtained was analyzed using standardized Beer’s criteria, adapted for the Chilean population, to define inappropriate medication use. A logistic regression model was performed to define risk factors for inappropriate medication use. RESULTS: Ten percent of subjects had a high risk of inappropriate medication use. The most common medications used were chlorphenamine, amitriptyline, diazepam, chlorpromazine, chlordiazepoxide and piroxicam. The risk factors detected were female gender, polypharmacy and a bad health self-perception. CONCLUSIONS: Inappropriate medication use is common among Chilean older people and should be discouraged.

RESUMO

INTRODUCTION: metabolic syndrome (MS) is a clustering of risk factors known to promote cardiovascular disease and diabetes. Environmental factors, such as unhealthy diet, play a major role in the development of this condition. In this study, we evaluated the prevalence of MS and its association with food intake quality among Chilean adults. METHODS: we analyzed data of 2 561 adults (≥ 18 years-old) included in the last National Health Survey (NHS 2009-2010) who had appropriate information to diagnose MS based on ATP III-NCEP guidelines. Consumption frequency of fish, whole grains, dairy, fruits and vegetables was also analyzed and associated with MS prevalence. Using a healthy diet score (HDS), we described the overall diet quality and further correlated it with MS prevalence. RESULTS: we found that lower whole grain intake was associated with greater MS prevalence (OR = 1.78; 95% CI: 1.088-2.919; p = 0.022). HDS showed better diet quality among women and in subjects with increasing age and higher educational level. A HDS < 3 points was associated with an increased risk of MS (OR HDS < 3 / HDS ≥ 3 = 3.69; 95% CI 1.884-7.225, p < 0.001). CONCLUSION: Chilean adult population exhibits a high prevalence of MS linked to a poor diet quality.

Introducción: el síndrome metabólico (SM) es un conjunto de factores de riesgo que predisponen a padecer enfermedad cardiovascular y diabetes. Una dieta poco saludable juega un rol importante en el desarrollo de esta condición. En este estudio evaluamos la prevalencia de síndrome metabólico y su asociación con la calidad de la dieta en adultos chilenos. Métodos: se analizaron los datos de 2.561 adultos mayores de 18 años de edad incluidos en la última Encuesta Nacional de Salud (ENS 2009-2010), que contaban con información para el diagnóstico de síndrome metabólico siguiendo los criterios de ATP III-NCEP. La frecuencia de consumo de pescado, cereales integrales, frutas, verduras y lácteos fue analizada y asociada a la presencia de SM. Por medio de un índice de dieta saludable (IDS), se evaluó la calidad global de la dieta y se correlacionó con la prevalencia de este síndrome. Resultados: un menor consumo de cereales integrales se asoció a una mayor prevalencia de síndrome metabólico (OR = 1,78; 95% IC: 1,088-2,919; p = 0,022). El IDS mostró que el consumo de alimentos tiene mejor calidad en mujeres y a mayor edad y mejor nivel educacional. Un IDS < 3 puntos se asoció con un mayor riesgo de síndrome metabólico (OR IDS < 3 / IDS ≥ 3 = 3,69 95% IC:1,884- 7,225, p < 0,001). Conclusión: la población adulta chilena presenta una elevada prevalencia de síndrome metabólico asociado al consumo de una alimentación de mala calidad.

RESUMO

BACKGROUND: Problems associated with alcohol consumption are prevalent in Chile, but little is known about the situation in the elderly. AIM: To perform a screening to detect alcohol-related problems and risks in the Chilean older people who travel. MATERIAL AND METHODS: The Alcohol Use Disorders Identification Test (AUDIT) questionnaire was answered by 1,076 travelers aged 60 to 93 years (66% females), who participated in trips organized by the Chilean National Tourism Service (SERNATUR). RESULTS: Seventy six percent of respondents acknowledged to have ingested an alcoholic drink during the last month. The average AUDIT score was of 2.2 ± 2.6. Only 3.7% of the sample had a score equal or higher than eight, considered as risky use. Within this last group, 60% had symptoms of alcohol dependence. A higher alcohol consumption was associated with male gender (p < 0.01), being younger than 75 years of age (p < 0.01), having a medium-low economic income (p < 0.01) and having a higher education level (p = 0.03). There was no significant association with the respondents' occupation. CONCLUSIONS: In this sample of Chilean traveling older people, there was a high prevalence of alcohol consumption, and nearly 4% of respondents had alcohol related problems.

RESUMO

Background:Delirium is an important problem in older medical inpatients. Aim: To assess if delirium is associated with higher mortality, functional decline or higher rates of readmission or institutionalization in a one year follow-up period. Material and Methods: Prospective cohort study of consecutive patients 65 years and older, admitted to a general hospital medical ward. A psychogeriatric team assessed patients every 48 h using the Confusion Assessment Method (CAM), functionality, acute severity and comorbidity scores. Analysis of one year mortality and telephone functional assessment was performed. Results: Five hundred forty two patients were enrolled and 35.4% had delirium. After one year, mortality was 34.9 and 13% in delirium and non-delirium cohorts, respectively (p < 0.01). After adjustment for covariates, delirium was independently associated with higher mortality, and higher functional decline and institutionalization. No significant differences were seen in readmission rates. Conclusions: Delirium was significantly associated with higher mortality and functional decline over a one year follow up period in geriatric inpatients.

RESUMO

We report a 79-year-old male patient presenting with progressive memory loss associated with anxiety and muscular pain. An extensive biochemical control revealed high serum calcium and parathormone levels, and normal thyroid hormones. Cognitive assessment prior to surgery was compatible with mild cognitive impairment, showing significant improvement two months after parathyroidectomy. Our case suggests that, although rare, primary hyperparathyroidism should be considered as a possible cause of cognitive decline in the elderly.

RESUMO

INTRODUCTION: An increase in visits to Emergency Departments by older adults has been reported, but there are no data available on this in countries in the early phases of demographic and epidemiological transition. This paper describes the characteristics of people over 60 years-old (AM) who visited the Emergency Department of the Hospital Clínico Universitario de la Pontificia Universidad Católica, Chile (SU-PUC), compared to those less than 60 years-old (AJ). MATERIAL AND METHODS: Demographic data and reasons for admission and re-admission were collected retrospectively from the SU-PUC monthly statistics report. Obstetrics, paediatrics and «scheduled admissions¼ were excluded. The frequencies were compared using Chi-squared (significance: P < .05). RESULTS: A total of 37,660 visits to the SU-PUC were recorded (81% AJ; 19% AM; with 8% being older than 75 years). No statistical differences were found in the visit time (70% daytime), or by season between the groups. A total of 7,414 (19.6%) of those who visited were hospitalised, with differences being detected between groups (AM: 48.9% vs 12.9% AJ; P < .001), particularly in those over 75 years (59%). The primary cause of admission was cardiopulmonary in AM (22%) and gastrointestinal in AJ (31%). Re-admissions were 10% in AM and 6% in AJ (P < .001). CONCLUSION: The use of SU by AM and some characteristics of their care process (hospitalisation) are similar to those found in countries in more advanced phases of demographic transition.

RESUMO

Background: There is no established definition of healthy aging in clinical practice, although it is a World Health Organization goal. Aim: To develop a clinical protocol to identify healthy older people living in the community and study their clinical, laboratory and functional characteristics. Material and Methods: Healthy people aged 60 years or older, were invited to participate in the study, by newspapers and radio, if they selfperceived as healthy, lived in the community, were functionally independent and had low disease burden. Potential participants were initially screened by telephone, and those who met the inclusion criteria were included. They had a comprehensive geriatric assessment which included clinical, anthropometric, laboratory and functional assessments. Results: Of 384 people who answered the call, 83 subjects aged 60 to 98 years (57 percent women) met the inclusion criteria of healthy older people. Seventy eight percent did not consume any medication, 100 percent were able to perform physical activities that required at least three metabolic equivalents (Mets). Basic laboratory showed that approximately 90 percent of subjects had normal values, using standard benchmarks established for an adult population. Conclusions: The protocol used in this work was able to identify healthy older people with low disease burden and good functionality. It also validated history and comprehensive geriatric assessment as reliable instruments to identify these subjects.

RESUMO

A special Committee on Internal Medicine and Public Health was established by Sociedad Médica de Santiago (Chilean Society of Internal Medicine) in April 2007 with the duty to write a Consensus Paper on the interaction between both branches of medical profession. The main objective was to find the common grounds on which to construct a positive approach to regain space for Internal Medicine, based on prevalent epidemiológica! features related to adult health issues. The authors describe the reasons to explain the gap between clinical medicine and population health and identify the nature and evolution of chronic diseases as the point of encounter between both. With Chilean health surveys data, they state that chronic diseases explain the high proportion of burden of disease, mortality and disability, and stress that by the year 2025 one in every five inhabitants will be over 65years of age, with ageing as another main problem for the health care sector. Population with multiple risks and multimorbidity is the most important challenge for the Chilean Health Care System. A new model of care is needed to tackle this scenario with new skills regarding psychosocial determinants of health. The leading role of internists and ideally geriatricians, will be crucial in this process and will help the implementation of sound population based interventions. Both individual and community level interventions will help to improve quality of life of Chilean families.

RESUMO

BACKGROUND: Delirium is an important problem especially in older medical inpatients. OBJECTIVE: The authors asked whether delirium and its duration are associated with higher mortality in a 3-month follow-up period. METHOD: In this prospective cohort study, inpatients age 65 and older were assessed every 48 hours with the Confusion Assessment Method. RESULTS: Of 542 patients enrolled, 192 (35.4%) developed delirium. After 3 months, mortality in the delirium cohort was 25.9%, and in the nondelirium cohort was 5.8%. Delirium was independently associated with mortality, and increased by 11% for every 48 hours of delirium. CONCLUSION: Delirium and increased delirium durations are significantly associated with higher mortality.

RESUMO

The speed of growth of the population of older adults has been much faster than expected in every country. In Chile today one out of ten persons is an older adult and in the next twenty years this proportion will duplicate. Population aging is a success of development but also presents a medical and social challenge. The health issues of the National Policy addressing the needs of the older population in Chile are severely delayed in their implementation due to the lack of human resources trained in medicine of older adults and geriatric services. The consensus evidence on how to develop appropriate geriatric health services for older adults should include services coordinated in a continuum, including health promotion and disease prevention targeting older people to achieve "healthy aging" in the majority of the older population; outpatient health care services; acute care in hospitals with physicians trained in geriatrics; special services for geriatric rehabilitation and restoration of function (short term care) and a variety of settings and services offering long term care ranging from home to institutions. To be able to implement this vision of appropriate, coordinated and integrated health and social services for older people, the country needs a minimum number of geriatricians (at least 260), health care teams trained in the basics of geriatrics and continuing development of human resources to meet the increasing demand on health services by the fast growing older population.

RESUMO

BACKGROUND: The aging speed in developing countries has been faster than predicted. Thus, health care systems must adapt to face this new scenario efficiently. The WHO designed the INTRA study to assess health promotion and protection actions in primary care, for people over 50 years of age. MATERIAL AND METHODS: Questionnaires designed by WHO were applied to 1,167 subjects (aged 50-94 years, 68% female) and 117 health care professionals attending and working respectively, at 33 health care centers of the Viña-Quillota Health Service. RESULTS: Twenty percent of subjects were illiterate and 25% had less than 6 years of instruction. Forty three percent could reach the health centre by public transportation and 92% did not need to be accompanied, 39% spent more than one hour to be attended and 71% considered that the service in the centre was good. Sixty seven percent attended regular appointments, 63% did not perform any physical activity and only half of them were advised to start such activity. Weight loss was recommended to 55% but only one third has achieved such goal. Only one third of patients admitted being interrogated about their drinking habits. Among subjects in whom blood pressure was measured, one fourth had abnormal values. CONCLUSIONS: Primary health care in Chile, although having health care programs for the elderly, is loosing opportunities to improve health status and quality of life of this age group.

RESUMO

BACKGROUND: Delirium is a common underdiagnosed and undertreated problem in elderly inpatients, associated to higher morbidity, mortality and health cost. AIM: To evaluate the prevalence of delirium at hospital admission in medically ill elderly patients and the attending physician's diagnosis and treatment of delirium. PATIENTS AND METHODS: In a prospective and descriptive study, consecutive patients aged 65 years or more, admitted to an internal medicine ward were evaluated by independent physicians, during the first 48 h of admission, to asses the presence of delirium. Diagnosis of delirium was based on the Confusion Assessment Method. Medical and nurse records were reviewed. Family was interviewed when necessary. RESULTS: One hundred eight patients (52% women, age range 65-94 years) with an APACHE II score of 11.6+/-5, were evaluated. Fifty seven patients (53%) had delirium (32% hyperactive, 72% hypoactive and 5% mixed). Delirium prevalence was significantly higher in older patients (66% among those aged 75 years or older versus 30% in younger, p <0.05) and among patients with more severe conditions (88% among those with an APACHE score over 16 versus 47% below that value, p <0.05). Medical records of patients with delirium showed that this diagnosis was present only in 32% and cognitive deficit was described in 73%. Ten percent of patients with delirium received sedative medication and 38% were physically restricted. There were no environmental interventions to prevent or control delirium. CONCLUSIONS: Delirium in elderly inpatients at this unit is an extraordinarily prevalent problem, seriously under diagnosed (68%) and under treated. This study should alerts our medical community to improve the diagnosis and management of delirium in elderly inpatients.

RESUMO

BACKGROUND: The number of nonagenarians is rapidly growing in Chile. This age group is mainly female, with higher frailty markers and in higher risk of being placed at nursing homes. AIM: To describe features of nonagenarian women and compare them with a group of women between 60-89 years, both living in nursing homes, in terms of disability and resource use at the institution. SUBJECTS AND METHODS: A total of 230 nonagenarian women and 460 women, aged 60-89 years, were evaluated in the nursing home Fundación Las Rosas de Ayuda Fraterna (only for poor elderly) in Santiago, Chile. The assessment instruments were the Geriatric Assessment instrument FEGAUC, functional and mental evaluation scales of Spanish Red Cross and the Resource Utilization System, RUG T18, an independent diagnostic classification system that allows the determination of resource use in terms of cost and personnel needs. RESULTS: Nonagenarian women had significantly (p <0.05) more disability (falls, urinary incontinence, memory problems and mobility difficulties), and were classified in RUG categories of higher resource utilization and dependency than younger women. Nevertheless, nonagenarians were a very heterogeneous group, almost half of them were able of moving by themselves or required little assistance and had minimal memory problems. CONCLUSIONS: Nonagenarian women assessed in this institution are an heterogeneous group, some with minimal disability and other more frail and dependent than the younger elderly women, being classified in higher categories of resource utilization RUG T18.
