Complementary and compensatory functions in social network relationships among the elderly

Examining the social networks of older adults receiving informal or formal care: a systematic review

PURPOSE

To address the care needs of older adults, it is important to identify and understand the forms of care support older adults received. This systematic review aims to examine the social networks of older adults receiving informal or formal care and the factors that influenced their networks.

METHODS

A systematic review was conducted by searching six databases from inception to January 31, 2023. The review included primary studies focusing on older adults receiving long-term care, encompassing both informal and formal care. To assess the risk of bias in the included studies, validated appraisal tools specifically designed for different study types were utilized. Network analysis was employed to identify the grouping of study concepts, which subsequently formed the foundation for describing themes through narrative synthesis.

RESULTS

We identified 121 studies relating to the formal and informal care of older adults' networks. A variety of social ties were examined by included studies. The most commonly examined sources of care support were family members (such as children and spouses) and friends. Several factors were consistently reported to influence the provision of informal care, including the intensity of networks, reciprocity, and geographical proximity. In terms of formal care utilization, older age and poor health status were found to be associated with increased use of healthcare services. Additionally, physical limitations and cognitive impairment were identified as factors contributing to decreased social engagement.

CONCLUSION

This review found that older people were embedded within a diverse network. The findings of this review emphasize the importance of recognizing and incorporating the diversity of social networks in care plans and policies to enhance the effectiveness of interventions and improve the overall well-being of older adults.

Older Adults' Social Relationships and Health Care Utilization: A Systematic Review

BACKGROUND

Deficiencies in older people's social relationships (including loneliness, social isolation, and low social support) have been implicated as a cause of premature mortality and increased morbidity. Whether they affect service use is unclear.

OBJECTIVES

To determine whether social relationships are associated with older adults' use of health services, independently of health-related needs.

SEARCH METHODS

We searched 8 electronic databases (MEDLINE, Embase, CINAHL, Web of Science, PsycINFO, Scopus, the Cochrane Library, and the Centre for Reviews and Dissemination) for data published between 1983 and 2016. We also identified relevant sources from scanning the reference lists of included studies and review articles, contacting authors to identify additional studies, and searching the tables of contents of key journals.

SELECTION CRITERIA

Studies met inclusion criteria if more than 50% of participants were older than 60 years or mean age was older than 60 years; they included a measure of social networks, received social support, or perceived support; and they reported quantitative data on the association between social relationships and older adults' health service utilization.

DATA COLLECTION AND ANALYSIS

Two researchers independently screened studies for inclusion. They extracted data and appraised study quality by using standardized forms. In a narrative synthesis, we grouped the studies according to the outcome of interest (physician visits, hospital admissions, hospital readmissions, emergency department use, hospital length of stay, utilization of home- and community-based services, contact with general health services, and mental health service use) and the domain of social relationships covered (social networks, received social support, or perceived support). For each service type and social relationship domain, we assessed the strength of the evidence across studies according to the quantity and quality of studies and consistency of findings.

MAIN RESULTS

The literature search retrieved 26 077 citations, 126 of which met inclusion criteria. Data were reported across 226 678 participants from 19 countries. We identified strong evidence of an association between weaker social relationships and increased rates of readmission to hospital (75% of high-quality studies reported evidence of an association in the same direction). In evidence of moderate strength, according to 2 high-quality and 3 medium-quality studies, smaller social networks were associated with longer hospital stays. When we considered received and perceived social support separately, they were not linked to health care use. Overall, the evidence did not indicate that older patients with weaker social relationships place greater demands on ambulatory care (including physician visits and community- or home-based services) than warranted by their needs.

AUTHORS' CONCLUSIONS

Current evidence does not support the view that, independently of health status, older patients with lower levels of social support place greater demands on ambulatory care. Future research on social relationships would benefit from a consensus on clinically relevant concepts to measure. Public Health Implications. Our findings are important for public health because they challenge the notion that lonely older adults are a burden on all health and social care services. In high-income countries, interventions aimed at reducing social isolation and loneliness are promoted as a means of preventing inappropriate service use. Our review cautions against assuming that reductions in care utilization can be achieved by intervening to strengthen social relationships.

Social Support, Health and Satisfaction among the Elderly with Chronic Conditions in Taiwan

This study examines possible relationships between perceived social support, physical and mental health, satisfaction towards hospital services, and satisfaction towards life-asa-whole, among the community elderly with chronic conditions. A sample of 172 Chinese elderly living in a metropolitan Taiwanese city were home-interviewed. Results indicated that (a) the elderly perceived good social support, and tangible support was the most important aspect; (b) the elderly did not perceive great impact of illness(es) upon their life, and both physical and mental health were satisfactory; (c) the elderly were generally satisfied with both the hospital services and life-as-a-whole; (d) apart from health and illness factors, social support appeared to have profound and pervasive protective effects on adjustment and satisfaction of the elderly.

Patterns of Health and Social Services Utilization

Utilization of an array of health and social services from formal and informal sources is studied here 1) to identify profiles of services utilization and 2) to predict the location of elderly in these profiles by a set of independent variables such as the sociodemographic characteristics of the elderly, their physical and mental health status and the density of their social support network. Two samples of non-institutionalized elderly living in two middle-sized towns were drawn from the universal old-age Canadian pension scheme. Their utilization of hospital, medical and pharmaceutical services was assessed, and their use of services for help with adivities of daily living was measured by a set of six indicators. A cluster analysis was run to identify profites of services utilization, and a discriminant analysis used the profiles as the criterion to be predicted by a set of variables. Five profiles of utilization were obtained; four of them identified elderly with very few experiences of services utilization and a fifth, a low number of elderly with utilization of all of the services listed in this study. Most of the elderly were users of a small subset of medical and social services. The location of elderly in the profiles was predicted by physical health status, coresidence and income. These results show that health and social services from both formal and informal sources are utilized by elderly. It is suggested that new types of formal agencies which consider the simultaneous delivery of social and health services will succeed inasmuch as they have the ability to interact with a system of informal care.

Positive Attitudes Toward Older People and Well-being Among Chinese Community Older Adults

We aimed to explore older people’s attitudes toward aging and to further examine associations of such attitudes with their well-being in a Chinese society— Taiwan. Face-to-face interviews were conducted to collect data using structured questionnaires from a random sample of community older people ( N = 316). We found that (a) older people possessed positive attitudes toward aging in general, but there were some group attitudinal differences associated with education attainment and urban residence; (b) older age, fewer social support, and less positive attitudes toward aging were related to more depressive symptoms; (c) younger age, greater social support, greater community participation, and more positive attitudes were related to higher happiness. The associations of positive attitudes with well-being were found after controlling for those of social support and community participation.

Caregiver strain: toward an enlarged perspective

This article attempts to broaden the conceptual perspective of caregiver strain by developing a generalized perspective that focuses on the demands and resources of caregiving. By extension, the perspective links caregiver strain to a typology relating caregiver strain and institutionalization. The result is intended to be a new and useful conceptualization for identifying factors that differentiate sources of caregiver strain and their consequences for both individuals and society.

Structural characteristics of social networks and their relationship with social support in the elderly: who provides support

The analyses presented here examine relationships between structural characteristics of social networks and two types of support (instrumental and emotional support) in a sample of community-dwelling individuals aged 65 and older. For each type of support, two dimensions are examined (1) the availability of such support and (2) the perceived adequacy of that support. Regression models, adjusting for age, sex, race and income show that structural characteristics such as total network size, number of face-to-face contacts and number of proximal ties are associated with greater availability of both instrumental and emotional support. The perceived adequacy of both types of support is most strongly related to the number of monthly face-to-face contacts. Comparisons of specific types of ties show that neither ones' spouse nor ones' children are primary sources of support. Rather the presence of a confidant is strongly associated with both dimensions of instrumental and emotional support; the presence of a spouse is not. And, while ties with children are most strongly related to aspects of instrumental support, ties with close friends and relatives are more strongly related to aspects of emotional support. Analyses of possible interactions show that for those without a spouse, confidants assume greater importance in providing emotional support. For those without children, ties with close friends and relatives assume a larger role relative to the perceived adequacy of both emotional and instrumental support.

Elderly persons without family support networks and use of health services. A follow-up report on social network relationships

This article compares the use of health services by a random sample of 394 noninstitutionalized elderly. Elderly persons without family used hospital emergency rooms (ER) 7 to 30 times more often than elderly persons with family in the area. Differences among them for physicians' visits or hospital utilization, however, were not statistically significant. Because elderly without family in the area had similar health status as elderly with family, absence of family access to a lay referral system is thought to be the principal reason for increased use of ER services, especially for nonurgent care.

Correlates of change in subjective well-being among the elderly

This study examines two related issues concerning the subjective well-being of elderly adults: change over time and correlates of that change. Data come from a three-wave panel study of 401 elderly residents in St. Louis. Residualized change score regression analyses indicate: there is change in subjective well-being over 4-5 months and over 12 months; the 4-5 month and 12 month changes are remarkably similar; the effect of subjective well-being over time indicates regression to the mean; and, only socioeconomic status is a significant predictor of change in subjective well-being (net of the effects of subjective well-being itself). The implications of these results for our understanding of subjective well-being in the elderly are discussed, as are the policy implications of the positive effect of socioeconomic status on changes in the subjective well-being of the elderly.
