The six-minute walk test in community dwelling elderly: influence of health status.

BACKGROUND: The 6 minutes walk test (6MWT) is a useful assessment instrument for the exercise capacity of elderly persons. The impact of the health status on the 6MWT-distance in elderly, however, remains unclear, reducing its value in clinical settings. The objective of this study was to investigate to what extent the 6MWT-distance in community dwelling elderly is determined by health conditions. METHODS: One hundred and fifty-six community dwelling elderly people (53 male, 103 female) were assessed for health status and performed the 6MWT. After clinical evaluation, electrocardiography and laboratory examination participants were categorized into a stratified six-level classification system according to their health status, going from A (completely healthy) to D (signs of active disease at the moment of examination). RESULTS: The mean 6MWT-distance was 603 m (SD = 178). The 6MWT-distance decreased significantly with increasing age (ANOVA p = 0.0001) and with worsening health status (ANCOVA, corrected for age p < 0.001). A multiple linear regression model with health status, age and gender as independent variables explained 31% of the 6MWT-distance variability. Anthropometrical measures (stature, weight and BMI) did not significantly improve the prediction model. A significant relationship between 6MWT-distance and stature was only present in category A (completely healthy). CONCLUSIONS: Significant differences in 6MWT-distance are observed according to health status in community-dwelling elderly persons. The proposed health categorizing system for elderly people is able to distinguish persons with lower physical exercise capacity and can be useful when advising physical trainers for seniors

Culture-level dimensions of social axioms and their correlates across 41 cultures

Leung and colleagues have revealed a five-dimensional structure of social axioms across individuals from five cultural groups. The present research was designed to reveal the culture level factor structure of social axioms and its correlates across 41 nations. An ecological factor analysis on the 60 items of the Social Axioms Survey extracted two factors: Dynamic Externality correlates with value measures tapping collectivism, hierarchy, and conservatism and with national indices indicative of lower social development. Societal Cynicism is less strongly and broadly correlated with previous values measures or other national indices and seems to define a novel cultural syndrome. Its national correlates suggest that it taps the cognitive component of a cultural constellation labeled maleficence, a cultural syndrome associated with a general mistrust of social systems and other people. Discussion focused on the meaning of these national level factors of beliefs and on their relationships with individual level factors of belief derived from the same data set.(undefined

Klinisch management van delier bij ouderen

Delier is een multifactorieel probleem dat vaak voorkomt bij ouderen. Het is een acuut psycho-organisch syndroom met acute en fluctuerende veranderingen in de aandacht, het bewustzijn en de cognitie, met als oorzaak een lichamelijke ontregeling of een ontwenning. Een delier gaat vaak gepaard met ernstige fysieke complicaties. Ook de psychologische impact op de patiënt en de familie is groot. Door het gebruik van een niet-medicamenteuze, multicomponente aanpak kan het zorgteam het risico op delier met 30% tot 50% terugdringen. Door het fluctuerende verloop en het caleïdoscopische karakter van het syndroom is het systematische gebruik van een screeningsinstrument bij patiënten met een verhoogd risico primordiaal voor een tijdige detectie en snelle behandeling van het delier. In deze bijdrage wordt er een overzicht geboden van de kenmerken en de verschillende verschijningsvormen van het delier, de risicofactoren, de negatieve gevolgen en de belangrijkste basisprincipes voor een doeltreffende interdisciplinaire preventie en behandeling van delier bij ouderen

Nurses' involvement in 'do not resuscitate' decisions on acute elder care wards

Aim. This paper reports the involvement of nurses in 'do not resuscitate' decision-making on acute elder care wards and their adherence to such decisions in the case of an actual cardiopulmonary arrest. Background. Previous literature showed that nurses are involved in half or less than half of 'do not resuscitate' decisions in hospitals, but their involvement in this decision-making on acute elder care wards in particular has not been investigated. Method. A questionnaire was sent in 2002 to the head nurses of all acute elder care wards in Flanders, Belgium (n = 94). They were asked whether nurses had been involved in the last 'do not resuscitate' decision-making process on their ward and whether nurses 'never', 'rarely', 'sometimes', 'often' or 'always' started resuscitation in case of cardiopulmonary arrest of patients with 'do not resuscitate' status and of those without. Results. The response rate was 86.2% (n = 81). In 74.7% of the last 'do not resuscitate' decisions on acute elder care wards in Flanders, a nurse was involved in the decision-making process. For patients with 'do not resuscitate' status, 54.3% of respondents reported that cardiopulmonary resuscitation was 'never' started on their ward, 'rarely' on 39.5% and 'sometimes' on 6.2%. For patients without 'do not resuscitate' status, nurses started cardiopulmonary resuscitation 'rarely' or 'sometimes' on 22.2% of all wards, and 'often' or 'always' on 77.8%. Conclusion. To make appropriate 'do not resuscitate' decisions and to avoid rash decision-making in cases of actual cardiopulmonary arrest, nurses should be involved early in 'do not resuscitate' decision-making. If institutional 'do not resuscitate' guidelines were to stress more clearly the important role of nurses in all kinds of end-of-life decisions, this might improve the 'do not resuscitate' decision-making process

Prevalence of patients with do-not-resuscitate status on acute geriatric wards in Flanders, Belgium

Background. Elderly hospitalized patients have low survival rates after cardiopulmonary resuscitation, especially in the long term. This study aims to investigate the prevalence of patients with do-not-resuscitate (DNR) status on acute geriatric wards and the characteristics of the preceding decision-making process. Methods. On all 94 geriatric wards in Flanders, Belgium (2002), the geriatrician who performed the bulk of clinical work was asked to fill in a retrospective structured mail questionnaire. Results. The response rate was 72.3%. A DNR status was attributed to 20.3% of patients. A significant higher prevalence of patients with DNR status was found on wards with a geriatrician who had been active in patient care for 15 years or less and on wards with a DNR policy. Mostly, DNR status was attributed when the patient's condition declined (34.0%) or became critical (29.0%). Geriatricians consulted at least one person in 81.0% of the cases: (head) nurses in 72.2%, next of kin in 61.9%, the patient's general practitioner in 22.6%, and the patient him- or herself in 15.7%. Reasons stated to make a DNR decision were the prognosis (68.1%) and the physical condition of the patient (62.2%). Age was mentioned in only 21.1% of the cases, always in combination with other reasons. Conclusions. One fifth of patients on acute geriatric wards in Flanders have DNR status. The decision to attribute DNR status is most often made late in the course of the disease. (Head) nurses and the patient's next of kin are often consulted, the patient and his or her general practitioner rarely
