Radiology Practices Employing Nurse Practitioners and Physician Assistants: Characteristics and Trends From 2017 Through 2019

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, there are ways for radiologist to work smarter. In this article, we present multiple short-term strategies to increase the effective radiologist workforce and/or increase workforce efficiency, in order to alleviate the current workload challenges. These strategies are derived based on 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.

Bridging the gap: Implementing a pilot radiology-focused curriculum in an acute care Nurse Practitioner program

ABSTRACT

Knowledge in diagnostic radiology and performance of point-of-care ultrasound are integral to acute care nurse practitioners (ACNPs) in the inpatient settings, especially true in specialty areas such as interventional radiology and critical care. However, existing ACNP training programs, including at our institution, often lack robust relevant course content. To address this educational gap, we designed and implemented a pilot acute care radiology course, incorporating a flipped classroom approach and hands-on simulation activities led by expert faculty. Our course evaluation revealed high levels of student satisfaction, self-reported confidence, and perceived course effectiveness. The course aligns with key competencies outlined by the American Association of Colleges of Nursing, demonstrating its potential to advance ACNP education in radiology content.

Growing Pains of Nonphysician Providers in Radiology

Nonphysician providers (NPPs) place in medicine continues to evolve regardless of controversy. NPPs presence in academic and private practices continues to grow in all fields. Despite their growth, there remains Contention and debate about the capability, safety, efficiency, and aptitude of NPP's abilities for proper image ordering, image interpretation, and performing radiology-related tasks. NNPs role in healthcare across the United States continues to grow in all facets of healthcare, including radiology and radiologist related procedures. The claims submitted by NPPs involving radiology have significantly increased. However, current research suggests that the current scope of practice maintains the levels of capability, safety, efficiency and aptitude of a physician. It is imperative to note that there remains no evidence comparing diagnostic accuracy/errors between NPPs and radiologists. Despite the increased radiology services rendered by NPPs, the output of NPPs is still fractional compared to radiologists but it is mostly fluoroscopy and radiography. As with medical student education, the education for NPPs has continued to grow to encompass more aspects of medicine, including radiology. Evidence-based programs for NPP radiology training offers potential to encourage proper radiology service rendering. 10,15 NPPs are skilled in their ability to provide care for specific common conditions and potential greater ability to follow protocol. All of these factors promote the opportunity to take tedious tasks and/or cases from overworked radiologists to pursue greater generation of profit and work-life balance.

Professional Services Rendered by Nurse Practitioners and Physician Assistants Employed by Radiology Practices: Characteristics and Trends From 2017 Through 2019

PURPOSE

With radiology practices increasingly employing nonphysician practitioners (NPPs), we aimed to characterize specific NPP clinical roles.

METHODS

Linking 2017 to 2019 Medicare data sets, we identified all claims-submitting nurse practitioners and physician assistants (together NPPs) employed by radiologists. NPP-billed services were identified, weighted by work relative value units, and categorized as (1) clinical evaluation and management (E&M), (2) invasive procedures, and (3) noninvasive imaging interpretation. NPP practice patterns were assessed temporally and using frequency analysis.

RESULTS

As the number of radiologist-employed NPPs submitting claims increased 16.3% (from 523 in 2017 to 608 in 2019), their aggregate Medicare fee-for-service work relative value units increased 17.3% (+40.0% for E&M [from 79,540 to 111,337]; +5.6% for procedures [from 179,044 to 189,003]; and +74.0% for imaging [from 5,087 to 8,850]). The number performing E&M, invasive procedures, and imaging interpretation increased 7.6% (from 329 to 354), 18.3% (from 387 to 458), and 31.8% (from 85 to 112), with 58.2%, 75.3%, and 18.4% billing those services in 2019. Paracentesis and thoracentesis were the most frequently billed invasive procedures. Fluoroscopic swallowing and bone densitometry examinations were the most frequently billed imaging services. By region, NPPs practicing as majority clinical E&M providers were most common in the Midwest (33.5%) and South (33.0%), majority proceduralists in the South (53.1%), and majority image interpreters in the Midwest (50.0%).

CONCLUSIONS

As radiology practices employ more NPPs, radiologist-employed NPPs' aggregate services have increased for E&M, invasive procedures, and imaging interpretation. Most radiologist-employed NPPs perform invasive procedures and E&M. Although performed by a small minority, imaging interpretation has shown the largest relative service growth.

Osteopathic Versus Allopathic Radiologist Workforce Characteristics: A Medicare Administrative and Claims Data Analysis

PURPOSE

Radiologist medical school pathways have received little attention in recent workforce investigations. With osteopathic enrollment increasing, we assessed the osteopathic versus allopathic composition of the radiologist workforce.

METHODS

Linking separate Medicare Doctors and Clinicians Initiative databases and Physician and Other Supplier Files from 2014 through 2019, we assessed (descriptively and using multivariate panel logistic regression modeling) individual and practice characteristics of radiologists who self-reported medical degrees.

RESULTS

Between 2014 and 2019, as the number of osteopathic radiologists increased 46.0% (4.7% to 6.0% of total radiologist workforce), the number of allopathic radiologists increased 12.1% (representing a relative workforce decrease from 95.3% to 94.0%). For each year since completing training, practicing radiologists were 3.7% less likely to have osteopathic (versus allopathic) degrees (odds ratio [OR] = 0.96 per year, P < .01). Osteopathic radiologists were less likely to work in urban (versus rural) areas (OR = 0.95), and compared with the Midwest, less likely to work in the Northeast (OR = 0.96), South (OR = 0.95), and West (OR = 0.94) (all P < .01). Except for cardiothoracic imaging (OR = 0.78, P = .24), osteopathic radiologists were more likely than allopathic radiologists to practice as general (rather than subspecialty) radiologists (range OR = 0.37 for nuclear medicine to OR = 0.65 for neuroradiology, all P < .01).

CONCLUSIONS

Osteopathic physicians represent a fast-growing earlier-career component of the radiologist workforce. Compared with allopathic radiologists, they more frequently practice as generalist radiologists, in rural areas, and in the Midwest. Given recent calls for greater general and rural radiology coverage, increasing osteopathic representation in the national radiologist workforce could improve patient access.
