Access to health care for older persons in the United States: personal, structural, and neighborhood characteristics.

OBJECTIVE: To determine the contributions of personal, structural, and neighborhood characteristics to differential access to health care for older persons in the United States. METHODS: This study used the 1994 National Health Interview Survey, ages 65 and older (n = 12,341), 1990 census block group data, and data on health professional shortage areas. Logistic regression was used to model the probability of problems accessing care. RESULTS: The likelihood of access problems increased sharply with decreasing gradients of family income and for those lacking private health care insurance. Rural areas and poor areas were at a disadvantage in accessing care, whereas residents of neighborhoods that were homogeneous in ancestral heritage appeared better able to access care. DISCUSSION: Considering the high association between neighborhood and personal characteristics, it is notable that any neighborhood effects remained after combining them with personal effects.

Selected issues in long-term care: profile of cognitive disability of nursing home residents and the use of informal and formal care by elderly in the community.

In summary, this section suggests that hospital care and physician office care are frequently used community health care services. There were relatively few differences by sex, age, or race in patterns of community health service use. There were differences by sex, age, race, and level of ADL disability in the number of informal helpers a frail elder used. Marital patterns appear to be an important underlying influence on the number of informal helpers. When a spouse is present, he or she becomes the primary and only helper in many instances. The number of informal helpers that a frail elder had was associated with an increased risk of mortality and institutionalization. Overall, there is somewhat more stability than change in the number of informal helpers over the 2-year period. This section, however, could not identify if the composition of the informal helper network remained the same over time.

Measuring the activities of daily living: comparisons across national surveys.

The "activities of daily living," or ADLs, are the basic tasks of everyday life, such as eating, bathing, dressing, toileting, and transferring. Reported estimates of the size of the elderly population with ADL disabilities differ substantially across national surveys. Differences in which ADL items are being measured and in what constitutes a disability account for much of the variation. Other likely explanations are differences in sample design, sample size, survey methodology, and age structure of the population to which the sample refers. When essentially equivalent ADL measures are compared, estimates for the community-based population vary by up to 3.1 percentage points; and for the institutionalized population, with the exception of toileting, by no more than 3.2 percentage points. As small as these differences are in absolute terms, they can be large in percent differences across surveys. For example, the National Medical Expenditure Survey estimates that there are 60 percent more elderly people with ADL problems than does the Supplement on Aging.
