Among the 14.6% of American households experiencing food insecurity, approximately 2 million are occupied by older adults. Food insecurity among older adults has been linked to poor health, lower cognitive function, and poor mental health outcomes. While evidence of the association between individual or household-level factors and food insecurity has been documented, the role of neighborhood-level factors is largely understudied. This study uses data from a representative sample of 1,870 New York City senior center participants in 2008 to investigate the relationship between three neighborhood-level factors (walkability, safety, and social cohesion) and food insecurity among the elderly. Issues relating to food security were measured by three separate outcome measures: whether the participant had a concern about having enough to eat this past month (concern about food security), whether the participant was unable to afford food during the past year (insufficient food intake related to financial resources), and whether the participant experienced hunger in the past year related to not being able to leave home (mobility-related food insufficiency). Unadjusted and adjusted logistic regression was performed for each measure of food insecurity. Results indicate that neighborhood walkability is an important correlate of mobility-related food insufficiency and concern about food insecurity, even after controlling the effects of other relevant factors.

The development of cost effective models of hospital care and discharge planning for people with HIV is a vital policy issue. However, almost no data exist evaluating cost and quality differences in alternate hospital models of care. This empirical study retrospectively evaluates social work discharge planning for patients with HIV disease in two hospital care models: a cluster AIDS unit and general inpatient site beds. The independent effect of each hospital model of care on length of stay is assessed in a multivariate analysis, controlling for level of care needs and other social and clinical factors. Results reveal that the cluster AIDS unit, where a specialized AIDS social work staff works in collaboration with the interdisciplinary AIDS team, is associated with a significant reduction in hospital length of stay for persons with HIV disease and complex discharge planning needs. These results support the hypothesis that discharge planning services, performed by specialized social workers, are a cost effective investment for hospitals treating patients with complex chronic conditions, such as AIDS. Further research should be developed to systematically evaluate the cost effectiveness of hospital-based social workers, using prospective experimental designs, in order to establish the net impact of social work discharge planning services on patient and family outcomes and institutional and social costs.

Pediatric AIDS is a continuing problem because of maternal transmission. Medical management is often complicated by the loss of one or both parents and adverse home environments. This study explores the cost of inpatient and clinic care of children admitted with AIDS in 1988 or 1989 at Mount Sinai Medical Center in New York City, and also examines the social severity of the cases. Blue Shield allowances were used to price clinic visits and tests, and prices in a drug trade publication were used to determine medication costs. Inpatient costs calculated per person-month at risk amounted to $48,000 per year. Costs per person-month of clinic care averaged $461 (38% of which was for drugs), annualized to around $5,500. These costs are higher than those shown by previous studies. A few cases requiring intensive inpatient services accounted for a large percentage of costs. The social severity analysis, based on the family environment at first admission and later, revealed that households were often stressed by chronic illnesses, drug abuse, marital problems and poor residential quality. Given the circumstances in which pediatric AIDS develops, the activities of social workers to strengthen families are essential to facilitating compliance, maintaining health and minimizing use of the hospital.

We examined the prevalence of, and factors associated with unmet health service needs among persons with HIV disease. Data were examined from 1,851 participants in the U.S. AIDS Cost and Service Utilization Study, drawn from 26 medical care providers in 10 cities. Geographic areas with large numbers of AIDS cases, and health care providers within them were chosen as study sites. After completing a screener questionnaire, potential participants at each site were stratified by illness stage, HIV exposure route, and insurance status; a systematic random sample within those strata were selected for the study. Participants completed a comprehensive survey of HIV-related service use and costs, which also asked them to identify unmet health service needs. Analyses identified the relationship between unmet needs and: stage of illness, type of insurance, source of care, living arrangement, and AIDS prevalence of respondents' geographic region. At least one unmet need was reported by 20% of the sample. Needs for non-institutional services, e.g., dental care, mental health, and medications were more likely to be unmet than need for emergency room and hospital care. While most factors significantly affected the odds of having an unmet need, the greatest effects were found for private insurance and HIV asymptomatic status, both of which decreased the odds of unmet needs by approximately 50%. These findings suggest that insurance coverage for services required during the chronic phase of HIV illness is inadequate and should be augmented. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the potential benefits, harms, and economic consequences of digital rectal examination and measurement of prostate-specific antigen (PSA) for the early detection of prostate cancer.Data Sources: Relevant studies were identified from a MEDLINE search (1966 to 1995), reviews, bibliographies of retrieved articles, author files, and abstracts.Study Selection: Probabilities for individual clinical outcomes were derived from various sources, including the largest screening study of community volunteers to data, analyses of Medicare claims, and recently published meta-analyses of the outcomes of alternative treatment strategies. Cost estimates were based on the 1992 Medicare fee schedule.Data Extraction: A cost-effectiveness model for one-time digital rectal examination and PSA measurement was constructed to examine the possible outcomes.Results: If a favorable set of assumptions is used, one-time digital rectal examination and PSA measurement may increase average life expectancy by approximately 2 weeks at a reasonable marginal cost for men who are between 50 and 69 years of age. Considerable iatrogenic illness would occur. If less favorable assumptions are used, the estimated net benefit would decrease and cost-effectiveness ratios would dramatically increase. Even if favorable assumptions are used, the model suggests that screening adds only a few days to the average life expectancy of men who are older than 69 years of age. If the assumptions are less favorable, older men are harmed.Conclusions: The model suggests that screening may be reasonable in younger men if optimistic assumptions consistent with existing observational data are made. The lack of direct evidence showing a net benefit of screening for prostate cancer seems to mandate more clinician-patient discussion for this procedure than for many other routine tests.
