Radiology.

Potential cost-effective advantages of interventional radiology may lie in the performance of more common (and high-volume) procedures. The Food and Drug Administration has recommended that a mammography facility meet defined quality standards before payment by the Health Care Financing Administration.

Results of the 1993 survey of the American Association of Academic Chief Residents in Radiology.

RATIONALE AND OBJECTIVES: A survey of chief residents of academic radiology programs is conducted annually on behalf of the American Association of Academic Chief Residents in Radiology (A3CR2). Data are obtained to improve the training of diagnostic radiology residents and to increase the understanding of radiologists and their associates about issues of interest to radiologists in training. METHODS: Questionnaires were mailed to 133 accredited programs in the United States and Canada. A wide variety of demographic and common interest questions were asked. The analysis took into account geographic location of the responders and the size of the residency program. Comparisons were made to the data from prior years. RESULTS: Completed surveys from 93 programs (70%) were returned. The percentage of women residents is increasing. Important regional and size variations exist in several areas including salary, workload, prior clinical training, resident/fellow ratios, post residency plans, and call schedules. Although many chief residents feel knowledgeable about the health care system, opinions about the future of radiology and medical care are tentative. CONCLUSIONS: This survey provides important demographic information about academic radiology residency programs. The summary information regarding plans for fellowship training, resident call schedules, and opinions about socioeconomic issues may be useful for chief residents, program directors, and departmental chairmen.

The challenge of managed care and managed competition.

Payment for health care in the United States changed rapidly during the 1980s, with the changes often identified by three-letter acronyms such as HMO, PPO, DRG, and RVS (health maintenance organization, preferred provider organization, diagnosis-related group, and relative value system). Changes are likely to be even more rapid and fundamental in the next few years. "Managed care" and "managed competition" are the principal terms being used to describe these pending changes. In this paper, we briefly present the problems that have led to changes, the changes that have occurred, the changes likely in the future, the implications of these changes for radiologists, and how radiologists can respond most effectively. We concentrate on the implications of changes for radiologists and on how radiologists can respond effectively.

Results of the 1992 survey of the American Association of Academic Chief Residents in Radiology.

RATIONALE AND OBJECTIVES: The authors conducted the annual American Association of Academic Chief Residents in Radiology (A3CR2) survey of chief residents of academic radiology programs to evaluate commonalities and differences among radiology training programs. METHODS: The surveys were mailed to 125 accredited programs in the United States and Canada. The analysis of the returned surveys took into account the geographic region of the respondents. RESULTS: Chief residents from 72 training programs (58%) returned their completed surveys. There are important variations among training programs related to requirements for entry, salary, and night call, and how residents prepare for Board examinations. CONCLUSIONS: The A3CR2 annual survey provides important information for program directors regarding how their training practices might differ from others so that they might better evaluate their programs.

Radiology performed by nonradiologists in the United States: who does what?

OBJECTIVE: When nonradiologists perform radiologic procedures, rather than referring their patients to radiologists, utilization--and therefore costs--are high, and quality appears often to be poor. In light of these public policy concerns, the American College of Radiology developed a detailed descriptive analysis of radiology performed by nonradiologists. MATERIALS AND METHODS: Medicare data from 1989, which make up a uniform record of one third of the nation's health care, were the source of the information. These data are reasonably, although not exactly, representative of patients of all ages. We measured radiologic work, and nonradiologists' share of it, in professional component relative value units, using the Medicare radiology relative value scale. RESULTS: Nonradiologists performed 25% of all radiologic work in the United States; their share was 46% in offices and freestanding centers, 27% for hospital inpatients, and 8% for outpatients. Counting procedures (rather than work measured in relative value units), nonradiologists' share was 64% in offices and freestanding centers and 8% for inpatients. Nonradiologists performed two thirds of all work in sonography, half of interventional radiology/angiography, 15-17% of general radiology and nuclear medicine, and a few percent of CT/MR and radiation oncology. Cardiologists performed 10% of all radiologic work in the United States; internists 5%; and orthopedists, ophthalmologists, and family and general practitioners, 2% each. Almost half of radiologic work performed by nonradiologists consisted of coronary angiography and cardiac sonography, done principally by cardiologists. Radiologists do less than 5% of this work. Office and freestanding center general radiology, performed mostly by orthopedists and primary care physicians, accounted for one fourth of the radiologic work done by nonradiologists. CONCLUSION: The general radiology performed by nonradiologists is of a magnitude that easily could be transferred to radiologists, particularly because many unnecessary imaging studies would most likely be eliminated as a result. Such a transfer would reduce costs and probably improve quality but might sometimes decrease patient convenience. However, because many radiologists do not perform coronary angiography and cardiac sonography, a transfer of these responsibilities to radiologists would be problematic and likely to require extensive additional training of radiologists.

How accurate was GMENAC?--A retrospective review of supply projections for diagnostic radiologists.

In 1982, the Graduate Medical Education National Advisory Committee (GMENAC), a prominent national panel, predicted there would be 25,650 full-time equivalent (FTE) diagnostic radiologists, a 34% oversupply, by 1990. The radiologists involved in GMENAC, however, using models developed by the American College of Radiology, projected 19,800 FTE diagnostic radiologists in 1990, which was similar to the GMENAC estimate of need. The disagreement arose principally from different assumptions about residents entering the specialty. Recent data show there actually were approximately 21,900 FTE diagnostic radiologists in 1990. The radiologists' projection was 10% below this figure; the GMENAC projection was 17% above it. GMENAC erred principally in assuming diagnostic radiology residencies would not replace general radiology residencies, but rather be an addition to them. The radiologists erred principally in their assumption about the effects of the financial problems of hospitals on the number of residency positions. Accurate long-term projection of physician supply in individual specialties may well not be feasible.
