Recruiting radiologists: the 1991 hiring survey.

Recent studies present widely varying views on the radiologist staffing situation, ranging from a projected surplus of over 6,000 radiologists to an estimated shortage of 5,000. To help clarify the situation, the American College of Radiology undertook a stratified random sample survey of radiology groups' recruitment efforts and hiring results in 1991. This survey of 192 groups achieved a 78% response rate. It found that half of all groups recruited, seeking to fill a nationwide total of 1,900 positions. Larger groups were more likely to recruit than smaller ones. Groups filled 1,348 (71%) of these positions, while 552 positions remained unfilled, which was 2.8% of groups' total staff. Remaining vacancies ranged from 5% of total staff in the Northeast and 3% in the Midwest to 2% in the South and 1% in the West. The percentage of positions filled was higher (76%) in nonmetropolitan areas than elsewhere. The authors conclude that the supply of radiologists is very close to balancing the number of positions available; the disparity is about 1/10 of some numbers mentioned previously and is probably shrinking. Also, recruiting is not less successful in nonmetropolitan areas and small cities than elsewhere.

Diagnostic imaging in cancer care. The role of cost/benefit analysis.

As the cost of medical care rises, there is increasing need to analyze the costs and benefits of diagnostic imaging. A review of previous research shows reasonable success at defining costs and the ability to identify safety and risk, but limited data on defining benefits in economic terms. The technology to analyze costs and benefits is improving, and satisfactory research protocols and methods have recently become generally accepted. While research studies to determine costs and benefits or efficacy are themselves costly, time consuming, and difficult to perform in clinical practice, the wise allocation of medical resources in the US requires physicians in all specialties to evaluate the technology when we are responsible for its use.

Analysis of economics and use of MR imaging units in the United States in 1990.

Personnel from the 72 facilities with the most experience in MR imaging were surveyed, and 45 questionnaires were returned with data to study the economics and use of MR imaging facilities. The data from 1990 were compared with results of studies done in 1985 and 1987. The facilities studied were highly selected, and the data and conclusions are unlikely to be representative of all MR facilities currently operational in the United States. The "typical" MR unit operated about 66 hr per week and imaged 68 patients. Most procedures were examinations of the head and spine (73%), with examinations of bone and joint increasing in frequency (17%). Scheduling delays for both inpatients and outpatients have decreased since 1987, indicating that clinical demand is being met by MR facilities. The global (technical plus professional) charge for an examination was approximately $950, and the charge for IV contrast material was an additional $200. IV contrast material was used in approximately 40% of head and 20% of spine studies. The typical MR units in 1990 was used to examine more than 3000 patients per year at a charge of approximately $750 each for the technical component. Technical billings for each unit were approximately $2.3 million, and net revenues were almost $1.9 million. We estimate the annual operating cost of an MR unit in 1990 was $1.3 million, so the typical MR unit had an annual net profit of approximately $500,000. This is a considerable improvement from the economic position in 1985, when each MR unit was losing approximately $400,000 annually. We conclude that experienced MR imaging facilities are now profitable owing to increased efficiency and continually rising charges. We suggest the economic historical pattern demonstrated by MR imaging (large losses initially followed by profitability within several years owing to increased efficiency and higher charges) is a typical pattern for many new technologies with the current medical payment system in the United States.

Factors influencing choice of academic or practice careers in radiology.

Factors, both personal and job-related in nature, that influence career choice among radiology residents are identified. Twenty-six third and fourth year radiology residents at two separate locations, and 17 age-matched and sex-matched internal medicine residents completed a 30-minutes interview and rated themselves on a series of job-related competencies. Data were collected on five groups of variables: demographic data, residency-related variables, factors that influence career choice, self-descriptions, and personal competencies. The results indicate that residents who choose academic careers and those who plan to have private practice careers differ substantially in their reasons for career choice. An academic career is chosen because of its atmosphere, emphasis on research and specialized techniques, and opportunity for teaching. In contrast, private practice careers are selected because of the autonomy they allow, the accompanying lifestyle, and financial reimbursement.

The economic impact of technology on diagnostic imaging at a university medical center.

Diagnostic imaging procedures and charges were analyzed for the most recent 15 years (1973-1988) and projected for 5 years in the future (1993) by using recent trends in a large, university-based radiology institute. During the 20 years, procedure volume doubles, total charges increase by a factor of 10 without adjusting for inflation and by a factor of three after adjusting for inflation. The major reason for the increase in charges is a change in the mix of procedures with increasing emphasis on new technology (CT, MR, sonography, and nuclear radiology) and interventional procedures. New technology and interventional procedures will change from 5% of total procedures in 1973 to a projected 27% in 1993. These more complex and more costly procedures have resulted in a considerably higher share of the charges for radiology and are projected to be responsible for 73% of a $109 million total charge by 1993. The charges for traditional radiology procedures have risen at approximately the inflation rate. These data document that the considerable benefit derived from new technology is associated with considerable cost and that new technology procedures are a major economic factor in modern diagnostic imaging.
