RESUMEN

This report describes the decline in employer-based health coverage between 1989 and 1996 and the underlying causes of that decline--including rapidly rising worker premiums and other economic variables. The analysis combines data from a variety of sources, including the U.S. Census Bureau's Current Population Survey, the National Medical Expenditures Survey for workers with employer coverage, and annual KPMG Peat Marwick Surveys. The authors employed regression analysis to determine the relative importance of economic factors on an individual's probability of having employer-based coverage--as either a worker or dependent. In addition to providing a basis for measuring the impact of various factors on the level of coverage of workers and dependents during the 1989 to 1996 period, these models also allowed projection of coverage levels in future years under alternative assumptions about premium growth, employee contribution shares, and other economic factors.

RESUMEN

OBJECTIVES: To measure the potential savings from medical nutrition therapy (MNT) and to estimate the net cost to Medicare of covering these services for Medicare enrollees. This includes developing an estimate of the cost of providing medical nutrition services to the Medicare population and estimating the savings in hospital and other spending resulting from the use of these services. DESIGN: Analysis of longitudinal data from the Group Health Cooperative of Puget Sound (Seattle, Wash) for persons aged 55 years and older who have coverage for MNT services. SUBJECTS/SETTING: Persons aged 55 years and older who had diabetes (n = 12,308), cardiovascular disease (n = 10,895), or renal disease (n = 3,328) and who were covered under the Group Health Cooperative of Puget Sound, including Medicare beneficiaries enrolled in the plan's Medicare risk contract program. Extrapolation to the US Medicare population is based on data for persons served by the Group Health Cooperative of Puget Sound. INTERVENTION: The use of MNT. MAIN OUTCOMES MEASURE: Differences in health care utilization levels of persons with diabetes, cardiovascular disease, and renal disease who do and do not receive MNT. Differences in utilization were estimated for hospital discharges per calendar quarter, physician visits per quarter, and other outpatient visits per quarter. STATISTICAL ANALYSES PERFORMED: Multivariate regression models of changes in utilization for persons after they receive MNT services. RESULTS: Our analysis showed that MNT was associated with a reduction in utilization of hospital services of 9.5% for patients with diabetes and 8.6% for patients with cardiovascular disease. Also, utilization of physician services declined by 23.5% for MNT users with diabetes and 16.9% for MNT users with cardiovascular disease. The net cost of covering MNT under Medicare is estimated to be $369.7 million over the 1998 through 2004 period. The total cost of benefits is estimated to be $2.7 billion over this period. This would be partially offset by estimated savings of $2.3 billion resulting in net costs of $369.7 million. The program would actually yield net savings after the third year of the program, which would continue through 2004 and beyond. CONCLUSION: After an initial period of implementation, coverage for MNT can result in a net reduction in health services utilization and costs for at least some populations. In the case of persons aged 55 years and older, the savings in utilization of hospital and other services will actually exceed the cost of providing the MNT benefit. These results suggest that Medicare coverage of MNT has the potential to pay for itself with savings in utilization for other services.

RESUMEN

The tax expenditure for health benefits is the amount of revenues that the federal government forgoes by exempting the following from the federal income and Social Security taxes: (1) employer health benefits contribution, (2) health spending under flexible spending plans, and (3) the tax deduction for health expenses. The health tax expenditure was $111.2 billion in 1998. This figure varied from $2,357 per family among those with annual incomes of $100,000 or more to $71 per family among those with annual incomes of less than $15,000. Families with incomes of $100,000 or more (10 percent of the population) accounted for 23.6 percent of all tax expenditures.

RESUMEN

We report the first case of benign aldosteronoma of an ordinary size with calcifications. We review the clinical, clinical imaging, histopathological, and laboratory features of aldosterone-producing adrenal adenoma versus carcinoma. We conclude that no single feature is diagnostic, and the full range of data must be considered. Calcifications may not necessarily be a distinguishing point.

RESUMEN

The 103d Congress considered several health care reform bills that would encourage voluntary expansions of coverage through insurance market reforms, new tax deductions for premiums, and direct premium subsidies for low-income persons. We found that insurance reforms alone will do little to expand coverage. We also found that most of the proposed tax deductions would go to persons who already have insurance and would have little impact on coverage. Premium subsidies for low-income persons would greatly increase coverage. However, coverage would change little for those who would have to pay all or part of the premium.

RESUMEN

This DataWatch estimates the public cost of providing universal coverage under a managed competition model. First, a uniform benefit package is specified; next, the lowest-cost premium for this coverage is estimated, based on average costs in a well-managed health maintenance organization (HMO). Based on these estimates, the cost of premium subsidies and tax revenue effects are determined. It is estimated that if coverage is extended to currently uninsured persons using these estimates and assumptions, spending for these persons will increase 73.9 percent over current levels. The authors estimate a net increase of $47.9 billion in 1993 health spending under a managed competition program with low patient cost sharing. This includes savings of $4.5 billion from wider use of managed care and $11.2 billion in administrative cost savings.

RESUMEN

We have examined the systemic and renal hemodynamic effects of nitric oxide (NO) inhibition with NG-monomethyl-L-arginine (L-NMMA) in normotensive rats as well as in rats with hypovolemic shock induced by hemorrhage. L-NMMA increased mean arterial blood pressure (MAP) from 114 +/- 4 to 130 +/- 6 mmHg (P less than 0.05) in the nonhemorrhaged rats and from 61 +/- 3 to 89 +/- 3 mmHg (P less than 0.05) in the hypovolemic animals. The absolute increase in MAP was greater in the hypovolemic (31 +/- 3 mmHg) than in the nonhemorrhaged (15 +/- 2 mmHg) rats (P less than 0.05). An excess of L-arginine reversed the increase in MAP induced by L-NMMA in both groups. In the normotensive rats the increase in blood pressure was associated with an elevation in renal vascular resistance (RVR; from 6.5 +/- 0.7 to 8.2 +/- 0.9 mmHg.ml-1.min-1, P less than 0.05) so that renal plasma flow (RPF) and glomerular filtration rate (GFR) were unchanged. In contrast, in the hypotensive rats, the marked increase in MAP induced by L-NMMA infusion was not associated with a significant increase in RVR. As a result L-NMMA increased both RPF (from 6.0 +/- 0.4 to 7.8 +/- 0.4 ml/min, P less than 0.05) as well as GFR (from 1.7 +/- 0.2 to 2.5 +/- 0.2 ml/min, P less than 0.05). We conclude that NO is produced and modulates peripheral resistance in normotensive rats as well as in rats with hypovolemic shock. In the hypovolemic rats NO inhibition substantially improves RPF and GFR.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

We describe a girl with Hodgkin's disease limited to the abdomen. She had severe hypochromic, microcytic anemia with increased iron deposition in the liver. Abdominal Hodgkin's disease should be considered in the differential diagnosis of a child with hypochromic anemia, systemic symptoms, and lack of peripheral adenopathy.
