Postdischarge geriatric assessment of hospitalized frail elderly patients.

BACKGROUND: The diffusion of comprehensive geriatric assessment services has been rather limited in North America partly because of reimbursement and organizational constraints. OBJECTIVE: To evaluate the impact of a comprehensive geriatric assessment intervention for frail older patients that is started before hospital discharge and is continued at home. METHODS: Patients older than 65 years were selected who had either unstable medical problems, recent functional limitations, or potentially reversible geriatric clinical problems. Patients (n = 354) were randomly assigned to either the intervention group or a control group. Information on survival, readmissions, nursing home placement, medication use, and health status was collected at 30 and 60 days after hospital discharge. RESULTS: No differences were observed between the two treatment groups in survival, hospital readmission, or nursing home placement by 60 days. After adjustment for baseline characteristics, no significant differences were observed between the two groups on measures of physical functioning, social functioning, role limitations, health perceptions, pain, mental health, energy and/or fatigue, health change, or overall well-being. CONCLUSIONS: Although efficacy has been demonstrated for some forms of comprehensive geriatric assessment, the types of services that are easier to establish (inpatient consultation services and ambulatory assessment) have not been shown to improve outcomes. Our results indicate that outcomes are unaffected by a limited form of comprehensive geriatric assessment begun in the hospital and completed at home. Further efforts are needed to develop and to evaluate realistic approaches to comprehensive geriatric assessment.

Health outcomes among Hispanic subgroups: data from the National Health Interview Survey, 1992-95.

BACKGROUND: Within the next 50 years, Hispanics will become the largest minority group in the United States. The largest Hispanic subgroups are those of Mexican, Cuban, and Puerto Rican descent. The Hispanic population is heterogeneous in terms of culture, history, socioeconomic status (SES) and health status. In this report, various health status measures are compared across Hispanic subgroups in the United States. METHODS: National Health Interview Survey (NHIS) data aggregated from 1992 through 1995 were analyzed. NHIS is one of the few national surveys that has a sufficiently large sample size to adequately compare the different subgroups. Data are presented for four Hispanic origin subgroups--Mexican, Cuban, Puerto Rican, and "other Hispanic" persons--for the Hispanic population as a whole and for the non-Hispanic white and non-Hispanic black populations. These groups are compared with respect to several health status outcomes, providing both age-adjusted and unadjusted estimates. RESULTS: The health indicators for Puerto Rican persons are significantly worse than for the other Hispanic origin subgroups. For example, about 21% of Puerto Rican persons reported having an activity limitation, compared with about 15% of Cuban and Mexican persons and 14% of "other Hispanic" persons. In contrast, the health indicators of Cuban persons are often better than those of the other subgroups. For example, Cuban persons reported an average of 3 days per year lost from school or work, compared with about 6 days for Mexican and Puerto Rican persons and 7 days for "other Hispanic" persons. Mexican persons fare better than Puerto Rican persons on measures such as restricted activity days, bed disability days and hospitalizations. CONCLUSION: These data demonstrate clear differences in health status as well as indicators of socioeconomic status across Hispanic subgroups in the United States. Data on Hispanic subgroups facilitate the planning of public health services for various underserved populations.

The prevalence of functional limitations and disability in older persons in the US: data from the National Health and Nutrition Examination Survey III.

OBJECTIVE: To provide estimates by sex and age and by sex and race/ethnicity of the proportion of older Americans who have difficulty with functional limitations and daily activities. SETTING: The Third National Health and Nutrition Examination Survey (NHANES III) 1988-1994. DESIGN: A cross-sectional nationally representative survey. PARTICIPANTS: All persons aged 60 and older who completed a household interview (N = 6,866) during NHANES III (conducted 1988-1994). MEASUREMENTS: The self-reported physical and functional disability questions from NHANES III included: lower-extremity function, instrumental activities of daily living, basic activities of daily living, needing help with personal and routine daily activities, and use of assistive devices for walking. RESULTS: Non-Hispanic black and Mexican-American men and women generally reported significantly (P < .01) more disability than did non-Hispanic white men and women. Disability was greater for minority women than for men. For both men and women, the prevalence in disability increased significantly (P < .01) with age for each measure. CONCLUSIONS: These sex-age and sex-race/ethnicity national estimates of disability indicate that minority women may represent a vulnerable subpopulation.

Reliability and prevalence of physical performance examination assessing mobility and balance in older persons in the US: data from the Third National Health and Nutrition Examination Survey.

OBJECTIVE: This report provides reliability and prevalence estimates by sex, age, and race/ethnicity of an observed physical performance examination (PPE) assessing mobility and balance. SETTING: The Third National Health and Nutrition Examination Survey (NHANES III) 1988-1994. DESIGN: A cross-sectional nationally representative survey. PARTICIPANTS: All persons aged 60 and older (n = 5,403) who performed the PPE either in the mobile examination center (MEC) or in the home during NHANES III (conducted 1988-1994). MEASUREMENTS: The PPE included timed chair stand, full tandem stand, and timed 8-foot walk. RESULTS: Timed chair stand and 8-foot timed walk were reliable measurements (Intraclass Correlations > 0.5). Women were significantly slower (P < .001) than men for both timed chair stands and timed walk. Non-Hispanic white men and women did the maneuvers in significantly less time than non-Hispanic black men and women and Mexican Americans women (P < .001). CONCLUSIONS: Lower extremity functions measured by timed chair stand and walk are reliable. Women at every age group were more physically limited than men.

Geriatric home assessment after hospital discharge.

OBJECTIVES: To evaluate the feasibility of an intervention involving post-discharge geriatric home assessment and follow-up and to describe the spectrum of significant clinical problems identified during the home assessment. DESIGN: Prospective observational study nested within a randomized controlled trial. SETTING: Inpatient service of a large academic medical center in Southern California. PATIENTS: There were 152 adults aged 65 or greater who had one or more specific risk factors for functional decline or increased mortality, who were awaiting discharge from the hospital, and who were assigned to the intervention arm of a randomized controlled trial of post-discharge comprehensive geriatric home assessment. MAIN RESULTS: During the home assessment, the gerontologic nurse practitioner (GNP) identified new or worsening problems in 150 patients (99%); 61 problems (eg, serum sodium 125 mg/dL; severe orthostatic hypotension) were considered by a reviewing physician to require urgent medical attention. Older age, non-white race, and new incontinence were associated independently with a greater number of findings (P < 0.05). Based on the findings, an interdisciplinary team made an average of 3.4 recommendations per patient; only two of 111 requests for written approval of recommendations were rejected. CONCLUSIONS: Post-discharge visitation by a GNP to patients at high risk is capable of detecting a high yield of important and potentially reversible clinical problems. This multidisciplinary approach is acceptable to physicians. Research is needed to identify additional links between short hospital stays, impairment or instability at discharge, and adverse outcomes.

Appropriateness of the decision to transfer nursing facility residents to the hospital.

OBJECTIVES: To develop and test a standardized instrument, the purpose of which is to assess (1) whether skilled nursing facilities (SNFs) transfer residents to emergency departments (ED) inappropriately, (2) whether residents are admitted to hospitals inappropriately, (3) and factors associated with inappropriate transfers. DESIGN: A structured implicit review (SIR) of medical records. SETTING AND PARTICIPANTS: Using nested random sampling in eight community SNFs, we identified SNF and hospital records of 100 unscheduled transfers to one of 10 hospitals. MEASUREMENTS: Seven trained physician reviewers assessed appropriateness using a SIR form designed for this study (2 independent reviews per record, 200 total reviews). We measured interrater reliability with kappa statistics and used bivariate analysis to identify factors associated with assessment that transfer was inappropriate. RESULTS: In 36% of ED transfers and 40% of hospital admissions, both reviewers agreed that transfer/admit was inappropriate, meaning the resident could have been cared for safely at a lower level of care. Agreement was high for both ED (percent agreement 84%, kappa .678) and hospital (percent agreement 89%, kappa .779). When advance directives were considered, both reviewers rated 44% of ED transfers and 45% of admissions inappropriate. Factors associated with inappropriateness included the perceptions that: (1) poor quality of care contributed to transfer need, (2) needed services would typically be available in outpatient settings, and (3) the chief complaint did not warrant hospitalization. CONCLUSIONS: Inappropriate transfers are a potentially large problem. Some inappropriate transfers may be associated with poor quality of care in SNFs. This study demonstrates that structured implicit review meets criteria for reliable assessment of inappropriate transfer rates. Structured implicit review may be a valuable tool for identifying inappropriate transfers from SNFs to EDs and hospitals.

Primary care of long-stay nursing home residents: approaches of three health maintenance organizations.

OBJECTIVE: To describe the innovative programs of three health maintenance organizations (HMOs) for providing primary care for long-stay nursing home (NH) residents and to compare this care with that of fee-for-service (FFS) residents at the same NHs. DESIGN: Cross-sectional interviews and case-studies, including retrospective chart reviews for 1 year. SETTING: The programs were based in 20 community-based nursing homes in three regions (East, West, Far West). PARTICIPANTS: Administrative and professional staff of HMOs in three regions and 20 NHs; 215 HMO and 187 FFS residents at these homes were studied. MAIN OUTCOME MEASURES: Emergency department (ED) and hospital utilization. RESULTS: All HMO programs utilized nurse practitioner/physician's assistants (NP/PA), but the structural configuration of physicians' (MD) practices differed substantially. At nursing homes within each region, all three HMO programs provided more total (MD plus NP/PA) visits per month than did FFS care (2.0 vs 1.1, 1.3 vs .6, and 1.4 vs .8 visits per month; all P < .05). The HMO that provided the most total visits had a significantly lower percentage of residents transferred to EDs (6% vs 16%, P = .048), fewer ED visits per resident (0.1 vs .4 per year, P = .027), and fewer hospitalizations per resident (0.1 vs .5 per year, P = .038) than FFS residents; these differences remained significant in multivariate analyses. However, the other two programs did not achieve the same benefits on healthcare utilization. CONCLUSIONS: HMO programs for NH residents provide more primary care and have the potential to reduce ED and hospital use compared with FFS care. However, not all programs have been associated with decreased ED and hospital utilization, perhaps because of differences in structure or implementation problems.

The relationship of self-rated vision and hearing to functional status and well-being among seniors 70 years and older.

PURPOSE: To describe the relationship between self-reported visual and hearing impairment and an index of global functional status among seniors age 70 years or older. METHODS: A total of 7,320 United States community-dwelling persons aged 70 years or older participating in the 1993 Assets and Health Dynamics of the Oldest Old Survey (AHEAD) completed detailed questionnaires about their demographic, socioeconomic, and health status. Multivariate analyses of functional status (using a global index of functional status based on self-reported limitations in 11 activities) were conducted, controlling for demographic and socioeconomic status and common medical conditions, as well as independently for hearing and vision. RESULTS: Of the respondents, 27% rated their vision as fair or poor, whereas 25% rated their hearing as fair or poor. Controlling for demographic factors, socioeconomic status, medical conditions, and general health status, limitations in both vision and hearing correlated independently with worsened functional status. Controlling for income, wealth, and education did not greatly reduce the strength of the association between visual and hearing impairment and function. CONCLUSIONS: Visual and hearing impairment appear to have a significant relationship to overall functioning in the oldest old, regardless of income or wealth. By confirming these findings across income and household wealth groups, adjusted for medical conditions and general health status, in a nationally representative population of Americans age 70 years or older, this study provides a powerful added impetus to efforts for improving vision and hearing for all other Americans, including the oldest old.

Racial differences in functional status among elderly U.S. migrants from the South.

This study describes patterns of functional status among older blacks and whites by their history of birth in and migration out of the South. We used multivariate regression to analyze data on functional status of US-born non-Hispanic blacks (N = 1868) and whites (N = 13469) age 60 years or above. In general, the functional status of blacks who were born in the South and migrated was similar to that of blacks born outside the South and better than those born in the South who did not migrate. Whites who migrated from the South had functional status similar to those who did not migrate and worse than those born outside of the South. Socioeconomic status did not explain differences by race and migration history. These results differ sharply from mortality studies, which have found a consistent pattern of high mortality among black migrants from the South. Differences among race groups by migration history vary across health measures. Selective migration and selective survival may account for the complex patterns of racial differences in geographic distributions of function and health.

Long-term determinants of patterns of health insurance coverage in the Medicare population.

Using data from the 1990 Health Supplement to the Panel Study of Income Dynamics, we examine the determinants of patterns of insurance coverage among the elderly. Among those with supplemental insurance through an employment-based source, the primary determinant of having insurance is work history, specifically job tenure and occupation of household heads and their spouses. Among those who do not have employer-provided insurance, wealth is the most important economic factor in the purchase of private insurance. Blacks, persons with less education and women household heads are less likely to purchase supplemental insurance. We find little evidence that persons in prior poor health are more likely to purchase supplemental insurance, and the most important determinant of dental or drug coverage is having employer-based insurance. The current trend toward decreased generosity of post-retirement benefits implies that fewer older Americans will have insurance for these services.

Dental expenditures and insurance coverage among older adults.

Using data on 975 elderly persons from the 1990 Health Supplements to the Panel Study of Income Dynamics, we describe the predictors of expenditures for dental services. Forty-four percent of elderly persons reported using some dental services within a year. Thirteen percent had private dental insurance, and 8% had a separate dental policy. The average total expenditure for those who used any dental services was $378, 88% of which was paid out-of-pocket. Persons with a separate dental insurance policy, younger and better educated persons, and those with greater financial resources were more likely to use dental services.

The financial burden of prescription drug use among elderly persons.

Expenditures for prescription drugs are not covered by Medicare and are thus a potential source of large out-of-pocket expenditures for elderly persons. This study, using a new data source, the 1990 Elderly Health Supplement to the Panel Study of Income Dynamics (PSID), demonstrates that, among elderly persons, insurance coverage for drugs reduces the fraction of household income spent on prescription drugs by 50 percent. Groups most likely to benefit from insurance coverage are elderly women and those with common chronic conditions, low incomes, and rural residences.

Dealing with diversity: recruiting churches and women for a randomized trial of mammography promotion.

There is little documentation about the recruitment process for church-based health education programs. In this study, the authors recruit African American, Latino, and white churches and women members (age 50 to 80) for a randomized church-based trial of mammography promotion in Los Angeles County. Efforts to enhance recruitment began 10 months before churches were invited to participate and included a variety of community-based strategies. Subsequently, 45 churches were recruited over a 5-month period through group pastor breakfast meetings and church-specific follow-up. In close collaboration with the 45 churches, the authors administered church-based surveys over 6 months and identified 1,967 age-eligible women who agreed to be contacted by the program team. It was found that an extended resource intensive period of relationship-building and community-based activities were necessary to conduct church-based programs effectively, particularly among older and ethnically diverse urban populations.

The persistence of race and ethnicity in the use of long-term care.

We examine the use of nursing homes, formal personal care, informal Activities of Daily Living (ADL) assistance, and no care to identify racial differences in their use. Using the 1987 National Medical Expenditure Survey of both nursing homes and the community, multinominal logistic regressions controlled for predisposing, enabling, and need variables as well as other types of service use. Additional state-level variables make few changes in race/ethnicity parameters, indicating that race/ethnicity are not simply proxies for state-level variables. Older African Americans are less likely to use nursing homes than similar whites, with the lower institutionalization replaced by a higher use of paid home care, informal-only care, and no care. This suggests that formal in-home community care is not fully compensating for the racial differences in nursing home use. Persistent effects of race/ethnicity could be the result of culture, class, and/or discrimination that may impair equitable access to services.

Barriers to cancer prevention in the older person.

Barriers to cancer screening are numerous and include both immutable barriers, such as a patient's low income, as well as more mutable barriers; fortunately, most barriers are potentially mutable ones. These encompass, among others, doctor patient communication patterns, inadequate and inaccurate health information, at attitudinal barriers such as patient anxiety, and community barriers, such as the lack of a provider reminder system to patients that prompts compliance. One of the easiest enablers of patient screening to implement is for clinicians to communicate their enthusiastic belief in screening to their older patients. Numerous studies now have documented the effectiveness of the physician's role in increasing patient compliance with screening guidelines.

Health status measurement performance and health status differences by age, ethnicity, and gender: assessment in the medical outcomes study.

The comparative measurement performance of self-reported health status instruments for African American and Hispanic elderly has rarely been studied, despite evidence of their poor health status. This study examined psychometric performance and health status differences by age, ethnicity, and gender among 10,569 ethnically diverse patients who completed the Short-Form General Health Survey in the Medical Outcomes Study (MOS). Hispanics and African Americans tended to have slightly lower measurement performance than other ethnic groups. Compared with whites, health status scores for African American and Hispanic women were slightly but significantly lower. The small differences in health status by ethnicity may be due to the MOS sampling strategy, which excluded low-socioeconomic status minorities with poor education and no regular medical care. The psychometric performance of MOS health status measures should be examined in studies of ethnically diverse, community-dwelling, elderly populations who have poor access to care, poor education, and/or low socioeconomic status.

Frailty, family, and church support among urban African American elderly.

A community-based survey of 507 African Americans aged 60 and older from South Central Los Angeles was conducted to estimate the prevalence of frailty and describe the correlation between frailty, social support from family and church, and use of community services. Persons were considered frail if they met criteria for any of four conditions: functional impairment, depression, urinary incontinence, falls. Sixty-seven percent met criteria for frailty. Analyses revealed that frail elderly were significantly less likely to report feeling very close to family. Family contact, feeling that church was important, and receiving church support were similar for the frail and nonfrail. Frail elderly were more likely to use community services. These findings suggest that frail elderly in this population may not receive more support from family and church than nonfrail elderly. There is a need for caution when assuming families and churches in urban African American communities are able to support the most vulnerable elderly.

Two-year follow-up of AIDS education programs for impoverished women.

The long-term effects of two culturally competent AIDS education programs with different content on the risk behavior and AIDS-related knowledge of 410 homeless African American women 2 years after program completion were examined. Participants were members of a larger cohort of impoverished African American and Latina women recruited in Los Angeles from 1989 to 1991. Of a subsample of 527 African American women selected randomly for a 2-year follow-up interview, 410 (78%) were located and agreed to participate. Women participating in both AIDS education programs reported reduced HIV risk behaviors and demonstrated greatly improved AIDS knowledge at 2-year follow-up (p < .001). Women in a specialized program were less likely than those in a traditional program to report noninjection drug use at 2 years. Women in the traditional program had significantly better AIDS knowledge at follow-up (p < .001). These findings suggest that educational programs can produce sustained benefits among impoverished women.

Reproductive history, socioeconomic status, and self-reported health status of women aged 50 years or older.

OBJECTIVES: This paper describes the relationship between self-reported general health status and several facets of reproductive history. METHODS: We analyzed survey data on a national probability sample of 1341 women aged 50 and older from the Panel Study of Income Dynamics. We used multivariate regression techniques to control for differences in health indices that assessed health status and functioning. RESULTS: Women with a history of six or more completed pregnancies were found to be disadvantaged in educational attainment, financial resources, and health status compared with women with no or fewer pregnancies. When current sociodemographic factors were controlled, six or more pregnancies were associated with worse general health and worse physical role functioning. When sociodemographic factors and number of births were controlled, among women with at least one delivery, women who had experienced an infant's death reported worse health as measured by all three indices. Women with a first delivery before the age of 18 were more likely to report a functional limitation. CONCLUSIONS: Women with high parity status, a history of an infant's death, and an early first pregnancy may be at greater risk of poor health in later life.
