William Stewart Halsted: letters to a young female admirer.

OBJECTIVE: To present the first new information in the past 25 years concerning the life of Dr. William Stewart Halsted. This paper reports on recently discovered personal correspondence of Dr. Halsted, beginning at age 66, to a young lady, Elizabeth Blanchard Randall, 40 years his junior. SUMMARY BACKGROUND DATA: Dr. William Stewart Halsted is generally considered the most important and influential surgeon that this country has produced. During his Hopkins days in Baltimore (1886-1922) he was rather reclusive, and little is known of his personal life. He was married but had no children. Several biographies written by Halsted's contemporaries constitute the bulk of what is known about Halsted's personal life. METHODS: All extant letters from Dr. Halsted to Miss Randall were reviewed. Archival materials were consulted to understand the context for this friendship. The correspondence between Halsted and Randall took place during a 3-year period, although their acquaintance was probably long-standing. RESULTS: The letters reveal Dr. Halsted and Miss Randall's great and warm affection for each other, despite their 40-year age difference. The letters have a playful nature absent in Halsted's other correspondence. This relationship has not been previously noted. CONCLUSIONS: Late in Halsted's life, he developed a warm and affectionate relationship with a young lady 40 years his junior, as revealed in Halsted's correspondence. Halsted's warm, personal, and playful letters are in stark contrast to his biographers' portrayals of him as a more serious and reclusive person.

Financial performance and participation in Medicaid and Medi-Cal managed care.

This article assesses the participation and the financial performance of licensed health maintenance organization (HMOs) in the Medicaid market. The study found that participation by Medicaid Dominant plans has more than doubled from 11 percent in 1992 to 23 percent in 1998 while Medicaid membership in Commercial Dominant plans declined from 71 percent in 1994 to 51 percent in 1998. Both participating and non-participating plans incurred operating losses in 1998. Medi-Cal participating plans had higher operating margins than Medicaid participating plans throughout the United States. Interviews with key informants express concern about competence in program management, rate adequacy, decline in Medicaid enrollment, and turbulence forces of managed care market on Medicaid programs.

Setting the target for a better cervical screening test: characteristics of a cost-effective test for cervical neoplasia screening.

OBJECTIVE: To determine the potential effects on costs and outcomes of changes in sensitivity and specificity with new screening methods for cervical cancer. METHODS: Using a Markov model of the natural history of cervical cancer, we estimated the effects of sensitivity, specificity, and screening frequency on cost-effectiveness. Our estimates of conventional Papanicolaou test sensitivity of 51% and specificity of 97% were obtained from a meta-analysis. We estimated the effect of reducing false-negative rates from 40-90% and increasing false-positive rates by up to 20%, independently and jointly. We varied the marginal cost of improving sensitivity from $0 to $15. RESULTS: When specificity was held constant, increasing sensitivity of the Papanicolaou test increased life expectancy and costs. When sensitivity was held constant, decreasing specificity of the Papanicolaou test increased costs, an effect that was more dramatic at more frequent intervals. Decreased specificity had a substantial effect on cost-effectiveness estimates of improved Papanicolaou test sensitivity. Most of those effects are related to the cost of evaluation and treatment of low-grade lesions. CONCLUSION: Policies or technologies that increased sensitivity of cervical cytologic screening increased overall costs, even if the cost of the technology was identical to that of conventional Papanicolaou smears. These effects appear to be caused by relatively high prevalence of low-grade lesions and are magnified at frequent screening intervals. Efficient cervical cancer screening requires methods with greater ability to detect lesions that are most likely to become cancerous.

Factors affecting progress of Australian and international students in a problem-based learning medical course.

CONTEXT: Research on the factors affecting progress in medical schools has typically focused on mainstream (non-Indigenous Australian, non-international) students in traditional, didactic programmes. These results may not be applicable to students, particularly those from culturally diverse backgrounds, undertaking problem-based learning courses. OBJECTIVE: This study used qualitative methodology to explore and compare factors affecting progress for mainstream Australian students (non-Indigenous Australian, non-international) and international students (full fee-paying students who had relocated countries to study) in a problem-based learning medical course. Intervention strategies were devised on the basis of the participants' experiences. METHODS: Six focus group discussions were conducted (three with mainstream Australian and three with international participants). Transcripts of these discussions were coded and analysed independently by two researchers and discussed until consensus was attained. RESULTS: Participants identified both positive and negative experiences related to the course structure, which were consistent with previous findings. The participants' experiences demonstrated a relationship between sense of 'belongingness' to the medical school community, participation in learning opportunities and progress through the course. CONCLUSIONS: The results suggest that interventions aimed at reducing barriers to progress need to promote students' confidence, motivation and subsequent participation in course learning opportunities. These results have application to other problem-based learning courses particularly those which face the challenge of providing an optimal learning environment for students from diverse backgrounds.

Insurers' views of the partnership for long-term care.

The Partnership for Long-Term Care was established in 1986 to demonstrate the feasibility of implementing public-private collaborations to offer affordable long-term care insurance products to a broad range of individuals. A fall 1996 survey of long-term care insurers indicates that those who participate are major players in the market and that most plan to continue their participation. Insurers were motivated to participate because the Partnership provided an opportunity to contribute to "good" public policy, market a product with a state seal of approval, and potentially increase their market share. While the survey did reveal dissatisfaction with some aspects of the Partnership, it also demonstrated that it is possible to develop a working partnership between states and insurers despite the need for compromise.

Factors important in the purchase of partnership long-term care insurance.

OBJECTIVE: To understand the factors important in the purchase of long-term care insurance through the Robert Wood Johnson Foundation Partnership for Long-Term Care. DATA SOURCES: Information on the Partnership programs, telephone surveys, data on Partnership purchasers, and random sample frames. STUDY DESIGN: Logistic regression analysis is used to examine characteristics associated with the purchase of a Partnership insurance policy. Independent variables are health status, demographic and financial characteristics, knowledge, and attitudes. DATA COLLECTION: A telephone survey of Partnership purchasers and a random sample of the population in each Partnership state were conducted. Survey questions included health status, opinions about long-term care and long-term care insurance, financial planning, demographic characteristics, and income and assets. PRINCIPAL FINDINGS: Important in the purchase of a Partnership policy were variables associated with education and knowledge about long-term care. Other important factors include attitudes and health status. Partnership purchase is associated with higher income and asset levels up to a point, with the effect plateauing and decreasing at the highest income and asset levels. CONCLUSIONS: Improved education and knowledge are important in increasing long-term care insurance purchase. Attitudes about having a caregiver, and about the government's role in paying for long-term care as well as the potential purchaser's willingness to consider nursing home care affect policy purchase. Also associated with Partnership policy purchase are better health and middle income and asset levels.

Utilization of services in Arizona's capitated Medicaid program for long-term care beneficiaries.

The Arizona Long-Term Care System (ALTCS), Arizona's Medicaid program for long-term care (LTC) beneficiaries, capitates contractors to provide a full range of acute and LTC services to financially-eligible beneficiaries determined to be at risk of institutionalization. This article compares the acute care utilization experience of LTC beneficiaries in ALTCS with those in a fee-for-service (FFS) Medicaid program, linking data from both the Medicare and the Medicaid program files. Patterns of use observed in Arizona seem more consistent with a managed care environment than those observed in the FFS comparison. Rates of acute care utilization observed for both the capitated and the FFS program should be of interest to States considering incorporating LTC beneficiaries into their Medicaid managed care program.

Changes in Medicare billing patterns: implications for physician payment reform.

This paper examines the changes in the billing for office visits, hospital visits, and consultations in the Medicare program for the period of 1986 through 1988. The analysis does not correct for changes in beneficiary or provider characteristics over the three-year period. Findings indicate $75 million in additional Medicare expenditures due to change in pattern of physician charges for these three commonly performed groups of procedures.

Private health insurance and medical care utilization: evidence from the Medicare population.

This paper examines the impact of supplemental health insurance policy ownership on the use of health care services by the elderly. It employs a data base consisting of Medicare claims data from over 2,000 beneficiaries in six states, actual copies of their supplemental insurance policies, and detailed survey information. The results show that policy ownership has a substantial, positive impact on service usage and costs, particularly for beneficiaries in fair or poor health. The greatest impact was found for policies that provide first-dollar coverage.

The effectiveness of consumer choice in the Medicare supplemental health insurance market.

This article examines the factors that affect Medicare beneficiaries' choices in the supplemental health insurance market. Data include detailed survey information as well as copies of the health insurance policies owned by a sample of approximately 2,500 Medicare beneficiaries in six states during 1982. Logit analysis is employed to analyze the determinants of four dependent variables: whether a person owns (1) one or more private supplemental insurance policies, (2) two or more policies, (3) at least one policy that we define as "effective," and (4) a policy we define to be "less effective." Those who are better off from a socioeconomic standpoint appear to be making more effective choices in the supplemental health insurance market. However, there does not appear to be a relationship between consumer ignorance or vulnerability and the purchase of multiple supplemental insurance policies. Study results imply an important role for public policy in helping to provide the information necessary to ensure that the most vulnerable beneficiaries make insurance choices that are in their best interest.

Access and satisfaction in the Arizona Health Care Cost Containment System.

Results of a survey conducted in the summer of 1985 of beneficiaries of the Arizona Health Care Cost Containment System and a matched group of Medicaid beneficiaries concerning their access to and satisfaction with medical care services are described in this article. The Arizona Health Care Cost Containment System is an alternative to Medicaid's acute medical care coverage. The results of the study indicate few differences in access and satisfaction between the two groups of beneficiaries on access to care, reported use of services, or satisfaction with the care received.

Use of nonphysician providers in the Medicare program: assessment of The Direct Reimbursement of Clinical Social Workers Demonstration Project.

Rising Medicare costs and concern about inadequate access to physician services have prompted interest in extending independent practitioner status to nonphysician providers. This paper reviews the findings from a demonstration project that tested whether recognizing clinical social workers (CSWs) as independent practitioners in the Medicare program would be a cost-effective method to improve access to needed mental health services. The demonstration showed little impact on access and no clear evidence of savings, despite the lower cost of CSW services compared with those of psychiatrists. Differences between CSWs and psychiatrists in treatment patterns and treatment settings, however, suggested that for some patients CSWs might be an appropriate alternative source of care.

The effect of state regulations on the quality and sale of insurance policies to Medicare beneficiaries.

This paper examines the effects of state regulations on the quality of insurance policies sold to Medicare beneficiaries and on the amount of sales abuse reported in the sale of such policies. State regulations regarding such policies relate to policy content and format, minimum rates of return, sale of these policies related to disclosure requirements, consumer information activities, and penalties for agent and company abuse. This paper examines the impact of specific regulations on the ratio of the expected policy benefits per premium dollars and on the number and kind of abusive sales practices reported by purchasers and nonpurchasers in agent and mail sales. The study finds that loss ratio floors, minimum benefit standards, and the development of states of consumer information guides for prospective policyholders have a positive impact on the quality of the policies purchased. In addition, the study finds that the amount of abuse reported is less when insurance companies routinely issue press releases concerning agent or company misrepresentation and when consumer guides are developed and available from the state.
