Moderating effects of prior social resources on the hospitalizations of elders who become widowed

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.

Widowhood and depressive symptoms among older Chinese: do gender and source of support make a difference?

In this study, we examined the effects of gender and pre-bereavement social support from three different sources (spouse, adult children, and friends) on widowhood adjustment among older adults in China. Hypotheses were developed by integrating the literature in the West and the cultural context of China. Data came from a panel survey, conducted in 1991 (baseline) and 1994 (follow-up), of a probability sample of older persons in Wuhan, China. For the present analysis, only those who were married with children at baseline were selected (N = 1,263). About 10% of the sample experienced spousal death between the two measurement points. Multiple regression analyses suggest that widowhood had a negative mental health consequence for older Chinese. Social support from adult children buffered the deleterious effect of widowhood, whereas spousal support during the marriage increased one's vulnerability. Support from friends was not found to have a significant effect. Gender difference in the effect of widowhood was also not evident. In this study, we have extended bereavement and social support research to a developing nation, with some findings similar to and some different from studies in Western developed nations.

Promoting positive affect and diminishing loneliness of widowed seniors through a support intervention

Seniors are most vulnerable to conjugal bereavement. Although social support buffers the effects of bereavement, widows and widowers have lower levels of social support than married individuals. Self-help/support groups can supplement support from their depleted natural networks. Accordingly, the aim of this demonstration project was to examine the impact of support groups on widowed seniors' loneliness, affect, and perceived support. Four face-to-face support groups for widowed seniors were conducted weekly for a maximum of 20 weeks. Participants completed pretest, posttest, and delayed posttest measures of support need and support satisfaction, positive and negative affect, and loneliness/isolation. The statistically significant impacts of the intervention were enhanced support satisfaction, diminished support needs, and increased positive affect. There was a trend toward decreased social isolation and emotional loneliness. In postintervention semistructured interviews, bereaved seniors reported increased hope, improved skills in developing social relationships, enhanced coping, new role identities, and less loneliness. Community health nurse researchers could conduct randomized controlled trials of face-to-face and telephone support groups for bereaved people of all ages. Community health nurse practitioners could benefit from lessons learned about timing, duration, and selection of sensitive outcomes.
