Counting Family Caregivers
On this we all agree: most of the care required by chronically ill adults, persons 65 and older, and persons 65 and older with cognitive impairments is provided by "informal caregivers"---unpaid family members, friends, or neighbors. But documenting informal care, i.e., how many caregivers exist, what counts as caregiving, and how much time caregivers spend with their care recipients leads to methodological inconsistencies. One problem is that data sources count different populations at different times and with different purposes. Some surveys query care recipients as to who provides care; others ask caregivers about their caregiving activities. Surveys use somewhat different definitions of the care recipient of caregiving. Most use some form of Activities of Daily Living and Instrumental Activities of Daily Living in their definition. Although both are useful, neither reflect the degree of difficulty inherent in caring for people with various conditions, or recent additions of high-tech medical procedures and monitering to home care. In an attempt to quantify aspects of caregiving, researchers have conducted a number of studies that employ various methods and techniques. For example, Arno, Levine, and Memmott (1999) used the methodology below to determine the mid-range value of informal caregiving per year. They applied the average weekly figure of 18 hours of informal caregiving per week (National Alliance for Caregiving & American Association of Retired Persons, 1997) to the number of estimated caregivers (25.8 million) who care for persons 15 and older. This yielded a midrange estimate 24 billion hours/year. Then, 24 billion hours was applied to a midrange wage rate of $8.18/hour; the wage rate estimate was derived from averaging the current minimum wage ($5.15/hour) and the national rate for home health aides ($11.20/hour). Thus, the midrange value of informal caregiving totaled $196 billion (Exhibit 1), illustrating that the value of informal caregiving is 6 times greater than national health expenditures for home care and 2.4 times greater than expenditures for nursing home care (Exhibit 2). Another study, conducted by the Alzheimer’s Association (1999), provides some insight into the number of informal caregiving hours among recipients who have Alzheimer’s Disease. As demonstrated in Exhibit 3, Alzheimer’s caregivers report spending an average of 17.6 hours per week giving care. However, results from a study directed by Ernst and Hay (1994) yielded an average of 52.5 hours per week, thereby illustrating the inconsistencies found when using different methodologies. To gain a richer understanding of patterns and problems associated with caregiving, the United Hospital Fund (UHF) and the Visiting Nurse Service of New York, collaborated with the Harvard University School of Public Health to conduct a national survey of family caregivers. The survey results, which will be available from the UHF later this year, will document the particular roles and needs of elderly caregivers and their care recipients. For example, respondents were asked the sources (if any) of training to perform complex medical tasks, as well as assist with ADL’s. Caregivers were also asked about their interactions with the formal health care system, including home care nurses and home health aides. By identifying the needs of vulnerable groups of elderly caregivers and care recipients, the study will help policy makers to develop appropriate public policies and health care providers to promote more responsive administrative practices. We expect that this survey, and work conducted by other researchers, will define more accurately the spectrum of informal caregiving and develop more nuanced ways to report the caregiving experience as it is lived, not just as it is counted.
