Objectives. This study examined the characteristics, activities, and challenges of high-risk informal caregivers. Methods. Telephone interviews were conducted with a nationally representative cross-section of 1002 informal caregivers. Vulnerable caregivers with poor health or a serious health condition were compared with nonvulnerable caregivers. Results. Thirty-six percent of caregivers were vulnerable. Compared with nonvulnerable caregivers, vulnerable caregivers were more likely to have difficulty providing care, to provide higher-intensity care, to report that their physical health had suffered since becoming a caregiver, to be aged 65 years or older, to be married, and to have less than 12 years of education. Conclusions. Reliance on informal caregivers without considering the caregiver's ability to provide care can create a stressful and potentially unsafe environment for the caregiver and the care recipient.
An estimated 15 million to 25 million adults in the United States currently provide informal care (i.e., unpaid care) to relatives and friends.13 Recognition of informal caregivers' contributions was heightened recently by estimates that project the economic value of their services to be $196 billion,4 a figure that far exceeds national spending for home health care and nursing home care. With ongoing public and private sector efforts to limit postacute and long-term care payments, the health care system's reliance on family caregivers will inevitably intensify. Although informal care can positively affect the physical and psychological well-being of care recipients, its provision often comes at a personal cost to the caregiver. Past studies have shown that caregiving can adversely influence the caregiver's psychological health through added strain,5 stress,6,7 and depression.8 Moreover, family caregivers are less likely to engage in preventive health behaviors911 and may even be at increased risk for mortality.12 However, these effects are not the same for all caregivers.6,1214 For example, it has been suggested that certain factors such as race, advanced age, employment status, and inadequate social support increase the caregiver's risk for poor health outcomes.7,1519 Therefore, it appears that the added burden of caregiving may have a more severe impact on the well-being of particular subgroups of caregivers who have predisposing characteristics that place them at "higher risk" for adverse health outcomes. Past studies have rarely focused on high-risk caregivers per se or the nature of their caregiving tasks. The purpose of this study was to examine the characteristics, activities, and challenges of high-risk informal caregivers.
Study Design and Sample Random-digit dialing was used to conduct telephone interviews with a nationally representative cross-section of 4874 households between May and September 1998.20 Eligibility for study inclusion was restricted to persons aged 18 years or older who were directly providing unpaid care or arranging for paid care to a relative or friend at any time during the 12 months preceding the study. A randomly selected respondent within each household who met the aforementioned eligibility criteria completed a structured, pretested survey questionnaire. Interviews were conducted in English or Spanish and lasted, on average, 24 minutes. After initial screening, 83% (n = 1002) of individuals who met the eligibility criteria gave verbal consent to participate in the study. For the purposes of this study, informal caregivers who reported being in fair to poor health or having a serious health condition (vulnerable caregivers) were compared with caregivers without these characteristics (nonvulnerable caregivers).
Data Collection
Statistical Analysis
Descriptive Analysis Sociodemographic and relational characteristics of caregivers. Thirty-six percent of the caregivers surveyed were identified as vulnerable; that is, they reported being in fair to poor health or having a serious health condition. Vulnerable caregivers were more likely than nonvulnerable caregivers to be at least 65 years old, female, and married; to have less than a high school education; and to be primary caregivers (Table 1
Activities and challenges of caregivers. Vulnerable and nonvulnerable caregivers did not differ greatly in terms of the types of activities of daily living and instrumental activities of daily living care they provided (Table 2
Although both vulnerable and nonvulnerable caregivers were equally unlikely to have help from formal care providers, vulnerable caregivers were more likely to experience difficulty with providing care, to have unmet needs in providing care, and to report that their physical health had suffered since becoming a caregiver.
Multivariate Analysis
Informal caregivers and their advocates have created a new awareness of the challenges of caregiving in the current health care system. In addition to their roles as hands-on care providers and care managers, family caregivers also are trusted companions, surrogate decision makers, and patients' advocates. Many caregivers meet the demands of caring for a relative or friend in the midst of their own deteriorating health. In this population-based national study, 36% of the caregivers surveyed were vulnerable. Among these vulnerable caregivers, over half reported difficulty with providing care, about half were providing care for 20 or more hours per week, and over one third reported that their physical health had suffered since becoming a caregiver. Moreover, vulnerable caregivers were more likely than nonvulnerable caregivers to be providing higher-intensity care and to be aged 65 years or older. Yet vulnerable caregivers were no more likely than nonvulnerable caregivers to have received help from paid support services for their care recipients. Nearly 4 of every 5 caregivers in each category provided care without paid assistance even though vulnerable caregivers bore a heavier care burden and were in poorer health. These findings paint a disturbing picture that warrants the attention of public health policymakers and health care providers. In the US health care system, the major source of paid home health care is Medicare, which limits eligibility to the elderly and to younger people with disabilities. Medicare has strict definitions of homeboundedness, medical necessity, and the need for intermittent rather than continuous care. Home health aide services are provided only when there is a need for skilled nursing care. Furthermore, although aide services and help with activities of daily living were once readily available to any Medicare beneficiary whose physician certified that need, recent changes in the Medicare home health payment system provide disincentives for agencies to serve individuals with long-term care needs. Consequently, the availability of Medicare as a dependable supplement to family caregiving has been dramatically reduced. Although state Medicaid programs, which unlike Medicare have legal authority to provide long-term care, could fill the gap created by Medicare cutbacks, most have a strong nursing home bias. Many Medicaid programs are quite actively engaged in "Medicare maximization"a policy of shifting to Medicare as many home care costs as possible. Thus, recent changes in the policy environment, combined with continued reductions in hospital and nursing home lengths of stay, suggest that pressures on unpaid caregivers are likely to increase. Reliance on informal caregivers without considering the caregivers' ability to provide care can create a stressful and potentially unsafe environment for the caregiver and the care recipient. These findings signal a need for developing a broader array of accessible, affordable, and innovative services and programs that lend support to family caregivers in their roles. Although arguments in favor of supporting caregivers are many, one large incentive is that caregivers at increased risk for mental and physical health problems are likely to become care recipients themselves, further draining limited resources for conditions that are often preventable. The results of this study must be viewed in light of certain survey limitations specific to nonsampling error, such as nonresponse bias, coverage bias, item response bias, and question order and context effects. The margin of error for estimates in this survey was 3%. Efforts were taken to minimize sources of errors, including pilot testing the survey instrument with focus groups, devising alternative forms of the screening instrument, training interviewers, and providing extensive supervision during data collection. Moreover, up to 50 attempts were made to contact eligible participants. This study extends previous research on caregiving in several ways. First, in contrast to past research, which almost always has considered caregivers as 1 population, the present study separates caregivers on the basis of key health attributes that are likely to affect both the caregiver's long-term well-being and his or her ability to provide care. Second, rather than focusing primarily on the psychological burdens of caregiving, the present study examines the content, intensity, and duration of care provided by vulnerable caregiversaspects of caregiving that could exacerbate existing vulnerabilities over time. Taken together, the results of this study suggest that more than one third of caregivers, who are a vital and increasingly important resource to the health care system, are in the precarious position of providing intense and continuing care to others while suffering from poor health themselves. The importance of addressing the needs of these caregivers should not be underestimated.
