Correlates of wellbeing of spousal and children carers of disabled people over 65 in Spain.

BACKGROUND: The aim of this study was to evaluate the associations between carer's wellbeing and stressors and to assess if these associations are different for spousal and children carers of disabled elderly. METHODS: Information was collected by home interviews of a population sample of carers (N = 195), who were providing assistance in activities of daily living to a community-dwelling population over 65. Associations between indicators of wellbeing (number of depressive symptoms, number of physical symptoms, self-perceived health and life satisfaction) and caring stressors were examined, controlling for carer's socio-economic characteristics and health status. Hierarchical logistic regressions were used to fit the data. Religion and social support were included as resources and spousal and children differential associations were tested. RESULTS: The four indicators of wellbeing are moderately correlated, indicating a common underlying concept. Spousal carers have lower socio-economic status, poorer health and lower levels of wellbeing than children carers. However, children carers bear a significantly greater burden. In the multivariate analysis of the associations between wellbeing and stressors, the similarities between spouse and adult child carers are more striking than the differences. Emotional support was consistently associated with higher levels of wellbeing while the associations of religiosity and instrumental support with wellbeing did not reach statistical significance. CONCLUSION: As formal care services are being developed in Spain, their ability to work in a supportive way with family networks should be taken into account. Research should be carried out on patterns of formal care interventions that use the resources in the natural support network of the family.

Loss to follow-up in a longitudinal study on aging in Spain.

The objectives of this study were to describe follow-up dynamics in a longitudinal study on aging conducted in Spain between 1993 and 1997, and to identify the demographic, behavioral and health characteristics of persons who would later refuse to continue participating, move out of the area or be hard to locate (i.e., become lost to follow-up subjects). Data from the 1993 baseline survey were used to predict the probabilities of being lost to follow-up in the 1995 and 1997 waves. Structural multiple logistic regressions were fitted and mean probabilities were estimated to identify patterns of loss to follow-up. After 4 years, 52% of baseline participants remained in the study, 24% had died, 17% refused to continue participating, and 8.7% were impossible to locate. In the multivariate analysis, advanced age and living alone were independent predictors of loss to follow-up, and none of the health status variables remained significant. However, participation status in previous waves and the number of nonresponse items were strong independent predictors of further non-participation. Our results suggest that an attitude against participation in surveys may be an independent predictor of losses to follow-up and efforts should be made to retain this subgroup of the population in the study. Further research on reasons why people are unwilling to participate in surveys and strategies to retain people in longitudinal studies is needed.

Support from children, living arrangements, self-rated health and depressive symptoms of older people in Spain.

OBJECTIVE: To assess the association between emotional and instrumental support from children and living arrangements with the physical and mental health of older people in Spain. METHODS: A face-to-face home interview was carried out with 1284 community-dwelling people over 65 (response rate = 83%) randomly sampled according to an age- and sex-stratified sampling scheme in 1993 at Leganés (Spain). Close to 93% of the participants had children and 45% of them coresided with them. Depressive symptoms were assessed by the CES-D (Center for Epidemiologic study depression scale) and self-rated health (SRH) by a single-item question. Emotional support was measured with a six-item scale on affection and reciprocity. Instrumental support was assessed by help received from children in 17 activities of daily living. Four living arrangements were considered: Living with spouse only, living with a spouse and children, widower living alone, and widower living with children. RESULTS: Multivariate analysis controlling for age, gender, education and functional status showed that low emotional support and reception of instrumental aid were significantly associated with poor SRH. Being a widower and sharing living arrangements with children was associated with good SRH. Living arrangements modify some of the associations of support of children with SRH. Depressive symptoms were associated with low emotional support, reception of instrumental help and being a widower who did not share living arrangements with children. For widowers who do not cohabit with children, reception of instrumental aid is associated with low depressive symptomatology. DISCUSSION: Emotional support from children seems to play an important role in maintaining the physical and mental health of elderly people in Spain. Instrumental support is widely available. Coresidence with children is very common and it is associated with good self-perceived health and low prevalence of depressive symptoms in a culture where family interdependence is highly valued. Families should be protected and encouraged to continue care-giving through a variety of community services and respite care, adapted to their needs and preferences. Research should be undertaken to find more efficient ways to help family caregivers in the Mediterranean context.

The effect of medical work groups on hospital resource use.

This study tests the ability of medical work groups to overcome coordination problems related to group decision-making in allocating clinical resources to inpatients. The study was conducted over a 32-month period in two medium-sized acute-care hospitals located in Montreal, Quebec, Canada. The data were collected by hand from the medical charts of 10,456 patients in the surgical and medical departments. The Linear Structural Relations (LISREL) approach was employed to address the work-group issue using a task contingent model of work-group organization. In this model, the nature of the task is fundamental because its level of complexity determines both the organization of the work group and the use of resources. Medical work-group mechanisms should be efficient to the extent that resource utilization is explained solely by task characteristics rather than by work-group structure. In this study, the following two major organizational concepts were used as factors to explain resource use: task characteristics and work-group characteristics. Our analysis confirmed the main points of the task contingency theory as applied to the field of medicine. First, the results confirm that resource utilization is explained mainly by task complexity. Second, they confirm that medical work groups modulate their structures on the basis of task characteristics and do not explain resource use. The results also reveal a more complex model in which, for instance, the concepts of medical task and medical professional work are not easy to separate. The results highlight the interest in conceptualizing and analysing medical practice in work groups. It raises important issues that have seldom been taken into account in the study of medical practice variations, which has tended to focus on attending physicians.

Development of simple cognitive function measures in a community dwelling population of elderly in Spain.

OBJECTIVE: To develop and assess the consistency and validity of simple cognitive function measures for an elderly population with low levels of formal education for use in a longitudinal study of dementia. METHODS: Data were from the population longitudinal study 'Growing old in Leganés' (Spain). In 1993, a random sample of 1540 people over 65 was drawn from the City Roll of Leganés from which 1284 (83%) were successfully interviewed. Measures of memory and orientation were based on the SPMSQ (Short Portable Mental Status Questionnaire), the Barcelona test and the short story from EPESE (Established Populations Epidemiologic Studies of the Elderly). Non-response to a test item was coded as an error. Internal consistency was assessed by factor analysis and Cronbach's alpha. Construct validity was examined with multiple linear regressions of the proposed measurements on variables chosen from the existing literature on cognitive function. RESULTS: Two factors, memory and orientation, emerged from the factor analysis. Internal consistency of the proposed indexes for memory and orientation was acceptable. Memory and orientation scores were summed into one summary index of cognition. Associations between covariates and both cognitive indexes were in the expected direction. Among those highly functional, orientation was influenced by illiteracy due to higher error rates in the time orientation items based on dates; however, memory and summary scores were not significantly different by literacy status. A large proportion of the variance in IADL was explained by the memory and orientation measures. CONCLUSION: The memory and orientation indexes are valid and reliable measurements of cognitive function for use in a population of community dwelling elderly with low levels of formal education and high rates of illiteracy.

Women, drugs and HIV/AIDS: results of a multicentre European study.

BACKGROUND: In the light of rising human immunodeficiency virus (HIV) incidence rates amongst women in Western Europe, a multicentred, cross-sectional study was undertaken to explore the multitude of possible factors associated with HIV in a population of female injecting drug users (IDU). METHODS: Face-to-face interviews were conducted with 1198 female IDU recruited from a variety of settings in Paris, Madrid, Rome, London and Berlin. Their HIV status was determined from antibody testing of blood or saliva samples or from written confirmation of HIV test results from a physician. A hierarchical logistic regression model was used to identify direct and indirect associations between socioeconomic factors, marginalization and risk behaviour with HIV prevalence. RESULTS: The HIV prevalence in the sample of female IDU was 27.8% (range: 1.4% in London and 52.6% in Madrid). Factors independently associated with HIV prevalence in the regression analysis included: age >25 years (OR = 2.0-2.9), left full-time education before age 14 (OR = 2.4), no fixed address (OR = 2.2), previous imprisonment (OR = 1.4), commercial sex (OR = 1.3), having a regular HIV positive sexual partner (OR = 6.6), ever shared needles (OR = 1.5) and any sexually transmitted disease (STD) infection in the last year (OR = 1.7). CONCLUSIONS: The sexual behaviour and partners of female IDU in Western Europe are as important a component in explaining the HIV epidemic in this population as other risk factors, including high-risk drug taking behaviour. Homeless IDU women may be an important residual risk group warranting future preventive interventions and women with a history of STD should be a particular target for health education. Differences in HIV prevalence across cities are very large and may be related to differences in harm reduction policies.

Do people with HIV/AIDS disclose their HIV-positivity to dentists?

This study documents behaviours of people with HIV/AIDS regarding the disclosure of their HIV-positivity when seeking dental care. An anonymous survey was conducted in Québec, Canada, from 1993 to 1995, using a sample of 463 people with HIV/AIDS recruited from different sources. Over 80% of respondents reported having sought dental care since becoming aware of their positivity. Of these, 54% reported having always disclosed their HIV-positivity to dentists, while 25% reported never having disclosed this information to dentists. However, 83% of all respondents preferred that the dentist be aware of their HIV status. Respondents gave reasons related to the sociopathological impact of HIV infection to explain their behaviours. The predictors of disclosure of HIV-positivity to the dentist were: gender, main source of payment for dental care, prior disclosure of HIV status to family members, prior disclosure of HIV status to co-workers, and trust in the maintenance of confidentiality by the dentist. These results emphasize the need to use universal precautions in the dental office and to promote dentist-patient relations free of discrimination, so that people with HIV/AIDS are not reluctant to disclose their health status and are confident that such disclosure will lead to care best adapted to their condition.

Predictors of functional status in older people living at home.

OBJECTIVE: to describe changes in functional status of community-dwelling Spanish elderly people, followed for 2 years, and to identify socio-demographic and health characteristics that predict functional change. METHOD: we have analysed data from the first two waves of the longitudinal study, Ageing in Leganés, from a representative sample of community-dwelling people aged 65 and over (n=1273). Functional status was categorized according to a hierarchical scale as: completely functional, with functional limitations, with instrumental activities of daily living (IADL) disability, with activities of daily living (ADL) disability or deceased. Multinomial logistic regression was used to estimate the predictive value of selected 1993 socio-demographic and health status variables on 1995 functional status. RESULTS: prevalence of disability based on dependency in any of seven ADL items was 15.5%. Half of the respondents were disabled in at least one of 10 IADLs. Some improved functionally, others deteriorated. Men were more likely to recover function while women were more likely to enter and to remain in the IADL state. Socioeconomic factors were associated to baseline functional status and to functional status change on bivariate analysis. Number of chronic diseases, presence of cognitive problems and depressive symptoms predicted transitions, even after controlling for baseline functional status. CONCLUSION: although estimates of prevalence of disability among people over 65 are higher in Spain than in other European and North American countries, the pattern of functional changes, both in the direction of improvement and decline, seems to be similar.

Family, religion, and depressive symptoms in caregivers of disabled elderly.

STUDY OBJECTIVE: To explain the variations in depressive symptomatology among primary caregivers of community dwelling activities of daily living disabled elderly and to evaluate the role of family and religiosity on the mental health consequences of caregiving in Spain. DESIGN: Cross sectional study. SETTING: City of Leganés in the metropolitan area of Madrid, Spain. PARTICIPANTS: All caregivers of a representative sample of community dwelling activities of daily living disabled persons, aged 65 and over were approached. The response rate was 85% (n = 194). Depression was assessed by the Center for Epidemiologic Studies Depression (CES-D) Scale. MAIN RESULTS: Controlling for caregivers' income, education, health status, and caregiving stress, religiosity was associated with more depressive symptoms among children caregivers while for spouses the association was negative. Emotional support was negatively associated with depression, but instrumental support was not significant. CONCLUSIONS: Depressive symptomatology is frequent among Spanish caregivers of disabled elderly. This study concludes that religiosity and family emotional support play an important part in the mental health of Spanish caregivers. The role of religiosity may be different according to kinship tie and needs further investigation.

[Interaction of prescribed drugs in a population over 65 years of age].

OBJECTIVE: To assess the prevalence and the types of drug to drug interactions in a population 65 years and over and to identify the factors associated to the occurrence of interactions. DESIGN: Cross sectional study ("Aging in Leganés"), a community survey. SETTING: Community level. Leganés (Madrid). PATIENTS AND OTHER PARTICIPANTS: People 65 years and over (n = 1284, response rate 83%). MEASUREMENTS AND MAIN RESULTS: Information on use of health services and medication use was collected through home interviews. Drugs were classified by its active components and into therapeutic categories. Drug to drug interactions were identified using Hansten's classification. Bivariate and multivariate analysis were carried out to identify factors associated to the frequency of interactions. RESULTS: The prevalence of drug to drug interactions was estimated as 13.6%. Interactions of clinical significance occurred in 9.9% of the population 65 and over. Hypertension, diabetes, Parkinson and cardiovascular diseases are significatively associated to interactions. The number of visits to the specialists was a risk factor (OR = 2.1 for those with five or more visits), after controlling for specific chronic conditions. Contacts with primary care, age and sex of the elderly were not associated to the frequency of interactions. DISCUSSION: The frequency of interactions is associated to preventable factors. Improvements in the communication between specialists and primary care and cooperation with pharmacists could result in better monitoring of medication use in the elderly.

Gender differences in depressive symptoms among Spanish elderly.

The aim of this study is to describe gender differences in depressive symptomatology among an elderly Spanish population and to see whether women are more at risk than men and whether the effects of known risk factors for depression differ between the genders. Data come from the study Envejecer en Leganés (Growing Old in Leganés), where a representative sample of community residing elderly was screened by an at-home interview for high depressive symptomatology using the Center for Epidemiologic Studies Depression Scale (CES-D). Sociodemographic characteristics, health status, Activities of Daily Living and Instrumental Activities of Daily Living, disability, social support, and locus of control were measured as possible correlates of depressive symptoms. Screening was completed in 1116 subjects. The prevalence of high depressive symptomatology varied, being 19.6% for men and 46% for women (OR = 3.4; 95% CI = 2.6; 4.5). In addition to gender, comorbidity, low emotional support from children, lack of a confidant, few social activities, and a sense of lack of control were independently associated with high levels of depressive symptoms. None of the interactions of gender by the known risk factors of depression was significant. Although the prevalence of depressive symptomatology is higher in women than in men, the known risk factors do not totally explain the difference between genders in this population of Spanish elderly. This difference could be due to the cultural definitions of gender roles that have affected them throughout their lives.

Patterns of visits to hospital-based emergency rooms.

What are the functions of hospital emergency care in our society? How are these functions associated with the characteristics of emergency room users, their environment and with other available medical resources? To answer these questions, an ecological conceptual framework has been developed, along with a procedure which clearly distinguishes between the sources of individual variation (user characteristics) and ecological variation (the users' environment and available medical resources). Four different functions have been identified: (1) care of critical or urgent cases requiring treatment only available in a hospital, (2) care of urgent cases requiring treatment also available elsewhere than in a hospital, (3) care of non-urgent cases requiring treatment only available in a hospital and (4) care of non-urgent cases requiring treatment also available elsewhere than in a hospital. The ecological units selected for this study do not differ statistically with regard to the frequency with which emergency rooms are used for these four functions. However, certain individual factors predicting frequency of utilization do differ depending on the unit; for example, patient health status is not uniformly related to the use of emergency rooms for non-urgent reasons in all units. This association is particularly weak in socio-economically deprived units and more significant at higher socio-economic levels.

A conceptual framework for the analysis of health care organizations' performance.

Organizational performance remains an elusive concept despite its importance to health care organizations' (HCOs') management and analysis. This paper uses Parsons' social system action theory to develop a comprehensive theoretically grounded framework by which to overcome the current fragmented approach to HCO performance management. The Parsonian perspective focuses on four fundamental functions that an HCO needs to ensure its survival. Organizational performance is determined by the dynamic equilibrium resulting from the continual interaction of, and interchange among, these four functions. The alignment interchanges allow the creation of bridges between traditional models of organizational performance that are usually used as independent and competing models. The attraction of the Parsonian model lies in its capacity to: (1) embody the various dominant models of organizational performance; (2) present a strong integrative framework in which the complementarity of various HCO performance perspectives are well integrated while their specificity is still well preserved; and (3) enrich the performance concept by making visible several dimensions of HCO performance that are usually neglected. A secondary objective of this paper is to lay the foundation for an integrative process of arbitration among competing indicators and perspectives which is absolutely necessary to make operational the Parsonian model of HCO performance. In this matter, we make reference to the theory of communicative action elaborated by Habermas. It offers, we think, a challenging and refreshing perspective on how to manage HCO performance evaluation processes.

Care for Canada's frail elderly population: fragmentation or integration?

Budget constraints, technological advances and a growing elderly population have resulted in major reforms in health care systems across Canada. This has led to fewer and smaller acute care hospitals and increasing pressure on the primary care and continuing care networks. The present system of care for the frail elderly, who are particularly vulnerable, is characterized by fragmentation of services, negative incentives and the absence of accountability. This is turn leads to the inappropriate and costly use of health and social services, particularly in acute care hospitals and long-term care institutions. Canada needs to develop a publicly managed community-based system of primary care to provide integrated care for the frail elderly. The authors describe such a model, which would have clinical and financial responsibility for the full range of health and social services required by this population. This model would represent a major challenge and change for the existing system. Demonstration projects are needed to evaluate its cost-effectiveness and address issues raised by its introduction.

[The prevalence of and factors associated with falls in older persons living in the community].

BACKGROUND: To describe falls in urban community elderly people and to identify factors associated with their occurrence. MATERIAL AND METHODS: Data from an age and sex stratified sample of the elderly people living in Leganes (n = 1183). Potentially associated factors are explored in bivariate analyses and a multivariate logistic regression analysis. The variables are entered into the equations in the causal order hypothesized. RESULTS: 14% of the elderly persons in Leganes reported at least a fall in the previous twelve months, 41% of them had consequences, 19% ended in hospitalization. In the bivariate analyses significant positive associations were found with being older than 65, female, widowhood, having more than six chronic conditions, functional limitations in lower extremities, disability, urinary incontinence and sleep problems. In the multivariate model independent associations were observed for females, functional limitations of the lower extremities, cognitive deficit, visual impairment, urinary incontinence and sleep problems. CONCLUSION: The frequency of falls in the elderly population in Leganes, Madrid, is approximately half of that reported in international studies using similar methodology. However, associations with known risk factors are confirmed in our population. The association between falls and difficulties in falling asleep found in this study should be confirmed by others.

Factors determining compliance with screening mammography.

OBJECTIVE: To determine factors affecting compliance with screening mammography prescribed by family physicians. DESIGN: Secondary analysis of a nonrandomized trial. SETTING: University-affiliated family medicine clinic in Montreal. PATIENTS: Women aged 50 to 69 years who were given a written prescription for a screening mammography during their visit at the clinic between Oct. 12, 1991, and May 31, 1992, and who had not undergone mammography in the preceding 2 years and had never been treated for breast cancer. Information on the potential factors was obtained through a telephone questionnaire 2 months after the visit. OUTCOME MEASURES: Indicator of compliance presence of result of screening mammography in patient chart, potential factors influencing compliance: age, level of education, marital status, socioeconomic level, smoking status, perceived health status, perceived psychological well-being, risk factors for breast cancer, use of health services including frequency of Papanicolaou test, Health Belief Model variables. RESULTS: Of the 171 eligible women, 113 (66.1%) underwent the prescribed mammography within 2 months after the visit to the clinic, and 149 (87.1%) responded to the questionnaire. The patients' socioeconomic characteristics, perceived health status, health utilization indices and risk factors for breast cancer were not found to be predictors of compliance. The strongest predictor of compliance was the number of previous mammograms. Women who had undergone mammography previously were less likely to be noncompliant than those who had not (odds ratio [OR] 0.11, 95% confidence interval [CI] 0.02 to 0.51; p = 0.005). Women who did not comply were less likely than those who did to believe that a prescription from their physician would convince them to undergo mammography (OR 0.21, 95% CI 0.007 to 0.60; p = 0.004). Other factors associated with noncompliance were the expression of fear of mammography (OR 2.09, 95% CI 1.08 to 4.02; p = 0.03) and the lack of time to take the test (OR 3.07, 95% CI 1.21 to 7.80 p = 0.02). Being a smoker was negatively associated with compliance (OR 0.43; 95% CI 0.22 to 0.86; p = 0.02). The stepwise logistic regression model accounted for 87.5% of the outcome (chi2 for goodness of fit = 164.4; p = 0.0001). CONCLUSION: Family physicians who prescribe screening mammography, even to women who consult for other reasons, are likely to overcome some of the barriers observed in association with population screening rates. However, physician-oriented approaches are not likely to reach the 30% to 40% of reluctant women who appear to hold negative views toward physicians' recommendations. Further study is necessary to determine how better to reach these women.
