Short-Term Strategies for Augmenting the National Radiologist Workforce

The current radiology landscape has an imbalance between the rising demand for radiology services and the national radiologist workforce available. More vacant radiology positions exist than graduating radiology trainees. The origins of this problem are complex and require long-term solutions. Rather than working longer and/or faster, radiologists can work smarter. In this article, we present multiple short-term strategies to increase the effective radiologist workforce and/or increase workforce efficiency, to alleviate the current workload challenges. These strategies are derived from an analysis of possible practice-level changes in personnel, process, and physical plant. The impacts of the potential changes are estimated. No single change addresses the mismatch between supply and demand for radiology services. By creating an inventory of potential solutions, practices can choose the potential mechanism(s) to address the workforce shortage that best fit their needs and local environment.

Cultivating Physician Character in Diagnostic Radiology Through Virtuous Caring and Collaborative Professionalism

In the contemporary environment of patient- and value-centered care, it is no longer sufficient to limit the definition of an "excellent radiologist" to someone who is skilled at image interpretation. Since diagnostic radiologists are physicians, they are held to a certain character standard expected of a physician, whose primary objective is to serve the best interest of patients. An "excellent radiologist," then, is better defined as one who is both skilled at interpreting medical imaging and embodies the attributes of physician character. The concept of physician character can be understood as the interplay between the practice of the care-related virtues, such as empathy, compassion, and kindness, and cooperative efforts with nonradiologist health care team members, termed collaborative professionalism. The very nature of the work of diagnostic radiology, aided by advances in technology, increasingly isolates the radiologist from both patients and other care providers, making it difficult to find opportunities for virtuous care and collaborative professionalism. Using the moral intuitionist model of character development as a conceptual framework, we first delineate the challenges that diagnostic radiologists face in demonstrating virtuous caring and collaborative professionalism. Then, we explore strategies that diagnostic radiologists can employ to overcome these barriers, thereby cultivating their own physician character and setting an example for other radiologists, medical students, and trainees. Finally, we will examine some of the limitations of applying this theoretical model to the real world.

A Systematic Review of Fatigue in Radiology: Is It a Problem?

OBJECTIVE

The purpose of this study was to review current literature regarding radiologist fatigue.

MATERIALS AND METHODS

A literature search was performed using PubMed. Key words and Medical Subject Heading terms were used to generate refined queries with inclusion and exclusion criteria, focusing on fatigue and error. Results were selected according to these criteria: examined radiologist fatigue and radiologic error stemming from fatigue; experimental results measured as accuracy, error, or performance; and peer-reviewed publication. The risk of bias was addressed by including both quantitative and qualitative studies.

RESULTS

Twenty-seven articles were included, mainly primary research articles. Common outcome measures included subjective self-reports and tests to measure eyestrain. Reaction time was also recorded, accounting for variables such as age and experience. One group recommended that guidelines should be implemented regarding number of hours worked. Most recommended ergonomic interventions, proposing the implementation of tools to measure and standardize fatigue and optimize workflow, in conjunction with considering radiologists individually. Education in appropriate viewing habits and breaks were also suggested. Only one study with seven participants recommended that radiologists should sleep well to improve their performance and overall well-being, despite the undeniable evidence that radiologists are fatigued.

CONCLUSION

Fatigue is present in radiology and affects diagnostic accuracy.

Comprehensive review of the limitations of relative value unit measurements of productivity in academic departments

Measuring radiologist, especially sonologist, productivity has never been of greater interest than now, as radiology has moved from its historical status as a cost center to the largest revenue generator in most institutions. With more local institutional and federal oversight and regulation into the reimbursement and valuation of imaging procedures, including emphasis on outsourcing, overvalued procedures, and bundling, the ability to measure productivity and to draw meaningful conclusions from the data becomes increasingly imperative if we as radiologists and sonologists expect to contribute meaningfully to the process. This article presents a history of the "relative value unit" and discusses the valuation of radiologist/sonologist productivity in this era of ubiquitous high-technology implementation.

The performance of outside readings by radiology practices

OBJECTIVE

The purpose of our study was to determine how many radiology practices perform outside readings, what characteristics affect the prevalence and volume of outside readings, and how practices are paid for outside readings.

MATERIALS AND METHODS

We analyzed data from the American College of Radiology's 2007 Survey of Radiologists, a stratified random sample e-mail and telephone survey. A total of 480 survey responses were evaluated; responses were weighted to make them representative of all U.S. radiology practices. We provide descriptive statistics and multivariable regression analysis results.

RESULTS

Overall, 40% of radiology practices in the United States performed outside readings in 2007. Outside readings constituted an average of 11% of the workload of these practices and 4% of the total workload of radiologists in the United States. Other practice characteristics being equal, academic practices, government practices, radiology units of multispecialty groups, and small practices had particularly low odds of performing outside readings. If they did perform outside readings, then, other practice characteristics being equal, small practices, solo practices, radiology units of multispecialty groups, practices in the main cities of large metropolitan areas, and those in nonmetropolitan areas had, on average, a relatively large portion of their workload consisting of outside readings. By far, the most common methods of payment were directly billing for the professional component or receiving a flat fee per study.

CONCLUSION

Outside readings were a common activity among radiology practices in 2007. There was substantial variability among practice types, sizes, and locations in whether practices performed outside readings and, if so, how much outside reading they did.

What factors affect the productivity and efficiency of physician practices?

BACKGROUND

Increasing the productivity and efficiency of physician practices could help relieve the rapid growth of US healthcare costs and the expected physician shortage. Radiology practices are an attractive specific focus for research on practices' productivity and efficiency because they are home to many purportedly productivity-enhancing operational technologies. This affords an opportunity to study the effect of production technology on physicians' output. As well, radiology is a leader in the general movement of physicians out of very small practices. And imaging is by the fastest-growing category of physician expenditure.

RESEARCH DESIGN

Using data from 2003 to 2007 surveys of radiologists, we estimate a stochastic frontier model to study the effects of practice characteristics, such as work hours, practice size, and output mix, and technologies used in work production, on practices' productivity and efficiency.

RESULTS

At the mean, the elasticities of output with respect to practice size and annual hours worked per full-time physician were 0.73 and 0.51, respectively. Some production technologies increase productivity by 15% to 20%; others generate no increase. Using "nighthawks"--ie, contracting out after-hours work to external firms that consolidate workflow--significantly increases practice efficiency.

CONCLUSIONS

The general US trend toward larger practice size is unlikely to relieve cost or physician shortage pressures. The actual effect of purportedly productivity-enhancing operational technologies needs to be carefully evaluated before they are widely adopted. As the recently-developed innovations of nighthawks and hospitalists show, practices should give more attention to a possible choice to "buy," rather than "make," part of their output.

Radiology practices' use of external off-hours teleradiology services in 2007 and changes since 2003

OBJECTIVE

Our objective is to report patterns of utilization of external off-hours teleradiology services (EOTSs) in 2007 and changes since 2003.

MATERIALS AND METHODS

We analyzed non-individually identified data from the American College of Radiology's 2007 Survey of Member Radiologists and its 2003 Survey of Radiologists. Responses were weighted to be nationally representative of individual radiologists and radiology practices. We present descriptive statistics and multivariable regression analysis results on the use of EOTSs in 2007 and comparisons with 2003.

RESULTS

Overall, 44% of all radiology practices in the United States reported using EOTSs in 2007. These practices included 45% of all U.S. radiologists. Out-of-practice teleradiology had been used by 15% of practices in 2003. Regression analysis indicates that, other practice characteristics being equal, in 2007, primarily academic practices had lower odds of using EOTSs than private radiology practices. Also, large practices (>or= 30 radiologists) had lower odds of using EOTSs than practices with 15-29 radiologists. Small practices (1-10 radiologists) had high odds, but nonmetropolitan practices did not. There were no significant differences by geographic region of the United States.

CONCLUSION

Use of EOTSs was widespread by 2007, and it had been increasing rapidly in the preceding few years. Patterns of use were generally as might be expected except that nonmetropolitan practices did not have high odds of using EOTSs.
