Self-reported versus actual test ordering behavior among primary care clinicians.

To determine the accuracy of clinician self-reports, 38 clinicians were surveyed in a university-based health maintenance organization (HMO) practice on their thyroid function testing (TFT) patterns one year after the distribution of an educational intervention (the intervention). The mean of the absolute difference between self-reported and actual test ordering rates was 12%; the difference was greater than 20% for only 3 of 33 clinicians who ordered TFT for at least five patients during the study period. A strong association was found between self-reported change and the actual mean change in TFT postintervention ordering rates (p less than 0.0001). Results suggest that clinicians, at least in certain settings, can accurately estimate their utilization patterns and the effect of practice guidelines.

Magnetic resonance imaging. Diffusion of technology in an ambulatory setting.

To better understand technology diffusion in an ambulatory care setting, we analyzed adult outpatients' use of magnetic resonance (MR) and computed tomography (CT) imaging in a group-model HMO between 1986 and 1989. The use of MR, but not CT, increased at a rapid pace with only a small proportion of the scans being accounted for by primary care physicians.

The impact of OBRA on medical practice within nursing facilities.

Major changes in the federal oversight of nursing home care were passed by Congress and became law as the Nursing Home Reform Amendments of the Omnibus Budget Reconciliation Act of 1987 (OBRA 87). The final regulations to implement OBRA 87 were published in September, 1991. The intent of this article is to provide an overview of selected parts of the nursing home reform regulations, which have a direct impact on physician practice within nursing facilities, and to offer strategies for successful management of the changes that are required. A brief review of the origins of the legislation and the process by which law is turned into practice is provided as a context in which to understand the changes mandated by the Nursing Home Reform Amendments of OBRA 87.

An overview of allocation and rationing: implications for geriatrics.

Geriatricians are faced with increasing pressure from insurers and the public to control costs. At the same time, subspecialist colleagues, patients, and the courts often demand ever more costly high-technology interventions. This conflict will only intensify given the sustained increase in the percentage of GNP spent on medical care. A number of prominent biomedical ethicists and others have explored rationing of medical care services as one response to these concerns. This is the second in a series of articles in the Journal in response to the Oregon Health Decisions Initiative and is designed to provide (1) a brief ethical perspective on rationing and allocation; (2) an analysis of our present, largely implicit, approach to rationing and allocation; and (3) some suggestions that might move the United States closer to a more coherent and reasonable means of allocating and rationing health care.

Medicare reimbursement for geriatric assessment: report of the American Geriatrics Society Ad Hoc Committee on Geriatrics Assessment.

This ad hoc committee report from the American Geriatrics Society proposes the prompt initiation of Medicare reimbursement for geriatric assessment (GA) services (also termed comprehensive geriatric assessment or geriatric evaluation and management services). Despite an extensive body of literature documenting the effectiveness of GA for improving health care outcomes in many settings for identifiable groups of frail elderly patients, no explicit Medicare reimbursement mechanisms currently exist to cover GA services provided by either hospital or physician. We believe that new physician reimbursement codes specific for geriatric assessment should be established in the Current Procedural Technology (CPT-4) manual and that reimbursement for GA should be specifically provided under Part B of Medicare. Further, we believe that hospital reimbursement within the Medicare prospective payment system should be modified to encourage GA during inpatient stays for appropriate patients. This paper summarizes the background for these recommendations. It defines the major content of GA at three levels of intensity--screening, intermediate, and comprehensive. It describes the major sites for conducting GA--hospital, office, home, nursing home. Finally, it proposes criteria for targeting patients most likely to benefit from GA.

Effect of education and feedback on thyroid function testing strategies of primary care clinicians.

We examined the effect of an educational memorandum incorporating simple guidelines for thyroid function testing on test utilization in a primary care health maintenance organization practice. We then compared the effectiveness of a reminder alone or combined with individual test ordering feedback at maintaining an effect. The subjects were 17 physicians and 13 physician assistants and nurse practitioners separated into two similar study groups with little clinical interaction. Both groups responded to the education with increased compliance (from 36% to greater than 67%) with the recommended testing strategy. The group subsequently receiving only a reminder showed a further increase in compliance from 68% to 81% at 6 months and 79% at 12 months. The group receiving a reminder and feedback showed no subsequent change in testing pattern (65% compliance before the reminder-feedback and 64% at both subsequent measurements). The effect of the educational intervention was greater on nurse practitioners and physician assistants than physicians (absolute increase in compliance, 63% vs 28%). We conclude that education can be an effective tool for modifying clinician testing patterns to conform to simple clinical guidelines. Further study of the effect of education and other strategies on compliance with more complex guidelines is needed.

The decision to execute a durable power of attorney for health care and preferences regarding the utilization of life-sustaining treatments in nursing home residents.

One hundred three nursing home residents were interviewed regarding their preferences for the choice of an agent for health-care decision making while being offered the opportunity to execute a Durable Power of Attorney for health care. They also completed a questionnaire that tapped their preferences regarding the use of four types of life-support treatment under three hypothetical levels of future cognitive functioning. Factors that might influence these preferences, such as previous experiences with life-sustaining treatments, religious beliefs, and personal values, were also examined. Participants tended to choose their son or daughter as their agent for future health-care decision making. They had clear and consistent patterns of preferences regarding the utilization of life-sustaining treatment. Generally, participants opted not to be treated, although there was variability among participants. They were even less inclined to opt for treatment as their perceived level of future cognitive functioning declined, or when the life-sustaining treatment involved permanent rather than temporary procedures.

Financing long-term care. An insurance-based approach.

A joint public-private insurance program is the best approach to resolving the problem of financing long-term care. In this report, we describe one possible approach in detail. A modest expansion of the current (ie, after repeal of the Medicare Catastrophic Coverage Law of 1988) Medicare benefit for persons needing relatively short-term nursing home and home care services would be a first step. For those with extended long-term service needs, a non-means tested, publicly funded program with joint federal-state financing and administration would provide coverage after a substantial elimination period and with an income-related copayment. Private long-term care insurance purchased through employers before retirement or in the periretirement period, through use of income or equity accumulated in life insurance, pension funds, or home ownership, would be used to fund the exclusionary period or copayments of the public program by those who wish to have greater protection for income or assets. The role of Medicaid would be limited to paying for the deductible, copayments, and initial long-stay expenses of those with low incomes and limited assets.

Medical correlates of agitation in nursing home residents.

This paper examines the relationship between agitation and medical and psychiatric diagnoses. Agitation marked by aggressive behaviors (e.g., hit, kick) was related to dementia and impairments in activities of daily living. Physically nonaggressive behaviors (e.g., pacing, disrobing inappropriately) correlated with cognitive impairment, fewer medical diagnoses, and absence of a hearing loss. Verbally agitated behaviors (e.g., constant complaints) were manifested by residents with more physical diagnoses, mental disease (other than schizophrenia and affective disorders), more reported pain, and higher cognitive functioning than the population as a whole.

Financing long-term care. The growing dilemma.

The financing of long-term care is one of the largest and most vexing health care problems facing our society. The problem will be further exacerbated when the rate of growth in the number of persons needing long-term care is further accelerated by the graying of those in the "baby boom" generation. The current financing mechanism, which relies almost entirely on concurrent funding through either a means tested welfare program (Medicaid) or self-pay, is inequitable and inadequate even for our present needs. Despite the magnitude of the problem, only recently has sufficient attention been focused on finding alternatives to the current means of financing long-term care. The search for a solution has been hampered by multiple, and sometimes conflicting, policy and political considerations. After reviewing the demographic and social roots of our current dilemma and listing the major alternatives for financing long-term care, a series of basic principles and definitions are reviewed. These elements are meant to serve as guidelines to compare and evaluate the growing number of proposals which seek to create a more effective and equitable system for financing long-term care. Future articles in this section will detail some of the more promising approaches to the dilemma of financing long-term care.

Clinical funding for geriatric fellowship programs.

The Medicare program provides the largest single source of funding for the clinical portion of housestaff training programs. Despite the fact that the clinical training in geriatric fellowship programs focuses heavily on the care of Medicare recipients, the proportion of funds supporting geriatric fellowships that is derived from Medicare is actually smaller than that of most other fellowship programs. Legislation passed by Congress in 1986, and just recently implemented, creates an opportunity to increase Medicare funding for geriatrics. Those concerned with geriatric fellowship training must have a clear understanding of how Medicare funding for graduate medical education will occur under the new legislation if the opportunity is to be used effectively. Finally, other barriers created by general pressures on housestaff budgets that may interfere with capitalizing on the opportunity are discussed.

Physician Payment Reform. Implications for geriatrics.

A consensus has developed on the need for a major revision of physician reimbursement in the Medicare program. The Physician Payment Review Commission has recommended to Congress a series of far-reaching changes in the payment system, based on the development of a fee schedule using a Resource Based Relative Value System (RBRVS). This article explores the rationale for the recommendations and the probable impact on Medicare beneficiaries and their physicians if the changes are enacted. Special consideration is given to unique aspects of geriatric medicine, including comprehensive geriatric assessment.

Medical student instructional costs in a primary care clerkship.

Using a variety of techniques, such as logs kept daily by the faculty, direct observation, and on-site interviews, the authors determined the instructional costs of a required third-year primary care clerkship based in an ambulatory care setting. Included in the analysis were labor costs of both faculty members and nonfaculty personnel, space and materials, and general university overhead. Total instructional costs were $54.20/student/day. If other third-year clinical clerkships generate equivalent costs, the direct instructional costs of clerkships for third-year medical students would be in excess of $11,500/student/year. The study results imply that ambulatory-based teaching of medical students generates considerable costs and thus requires support from student tuition, federal or state government, or other sources.

The costs of a family practice residency ambulatory care program.

The cost of patient care service and education occurring in a family practice residency unit of a community based prepaid health program was determined from accounting records. The cost of producing the same number of patient visits in comparable family practice units which did not have residents on-site was determined in a similar manner. The cost per visit in the residency unit was $15.53 while that in the nonresidency unit was $13.92. There was an excess cost of $1.61 per visit in the residency, or, based on the number of residents present, a net cost of $7 per resident per day. None of the costs of central residency program administration or of ambulatory based subspecialty rotations were included. While a small increase (ten percent) in productivity or efficiency would result in the residency patient care unit itself being self-sustaining, this study casts considerable doubt on the ability of the model family practice residency unit to offset the full costs of the ambulatory care portion of family practice residency training.

The cost-effectiveness of three thyroid function testing strategies for suspicion of hypothyroidism in a primary care-setting.

OBJECTIVE: To determine the sensitivity and specificity of thyroxine (T4) and the cost-effectiveness of three testing strategies in the diagnosis of hypothyroidism in a primary care setting. DESIGN: 1) A retrospective chart review to determine sensitivity and specificity of T4 in diagnosing hypothyroidism; a cost-effectiveness analysis comparing ordering an initial T4 test alone, an initial thyroid-stimulating hormone (TSH) test alone, and T4 and TSH tests together in diagnosing hypothyroidism; a sensitivity analysis was performed on critical assumptions. SETTING: Primary care adult practice of a health maintenance organization. PATIENTS: Eight hundred sixteen consecutive patients suspected of having hypothyroidism who had both T4 and TSH tests performed. INTERVENTIONS: None. RESULTS: The sensitivity of a T4 cut-off of 7 micrograms/dl (90.3 nmol/L) in diagnosing primary hypothyroidism was 93% (95% confidence interval = 85-100%) and the specificity was 68% (95% confidence interval = 65-71%). The cost-effectiveness ratios of using an initial T4 or TSH test were about the same across a wide range of test characteristics and disease prevalence estimates. As the ratio of T4 to TSH test charges declines from 0.6 to 0.2, the marginal cost of the TSH-first method increases from $3,500 to $18,000 for each additional hypothyroid patient identified. Ordering both tests together was very costly compared with the single test methods ($125,000 for each additional case diagnosed) and remained so under a wide range of assumptions. CONCLUSIONS: When hypothyroidism is suspected, a TSH-first testing approach is generally preferable due to its greater sensitivity and, under most assumptions, only small increment in average or marginal cost per case compared with a T4-first method.
