The effect of orthopaedic surgeons' and interventional radiologists' availability on the priority treatment sequence for hemodynamically unstable pelvic fractures: a survey of US Level I trauma centers.

BACKGROUND: Most guidelines recommend both pelvic packing (PP) and angioembolization for hemodynamically unstable pelvic fractures, however their sequence varies. Some argue to use PP first because orthopaedic surgeons are more available than interventional radiologists; however, there is no data confirming this. METHODS: This cross-sectional survey of 158 trauma medical directors at US Level I trauma centers collected the availability of orthopaedic surgeons and interventional radiologists, the number of orthopaedic trauma surgeons trained to manage pelvic fractures, and priority treatment sequence for hemodynamically unstable pelvic fractures. The study objective was to compare the availability of orthopaedic surgeons to interventional radiologists and describe how the availability of orthopaedic surgeons and interventional radiologists affects the treatment sequence for hemodynamically unstable pelvic fractures. Fisher's exact, chi-squared, and Kruskal-Wallis tests were used, alpha = 0.05. RESULTS: The response rate was 25% (40/158). Orthopaedic surgeons (86%) were on-site more often than interventional radiologists (54%), p = 0.003. Orthopaedic surgeons were faster to arrive 39% of the time, and interventional radiologists were faster to arrive 6% of the time. There was a higher proportion of participants who prioritized PP before angioembolization at centers with above the average number (> 3) of orthopaedic trauma surgeons trained to manage pelvic fractures, as among centers with equal to or below average, p = 0.02. Arrival times for orthopaedic surgeons did not significantly predict prioritization of angioembolization or PP. CONCLUSIONS: Our results provide evidence that orthopaedic surgeons typically are more available than interventional radiologists but contrary to anecdotal evidence most participants used angioembolization first. Familiarity with the availability of orthopaedic surgeons and interventional radiologists may contribute to individual trauma center's treatment sequence.

Análisis del rol de los exámenes de imagen en el régimen de garantías explícitas en salud en Chile / Analysis of the role of imaging exams in the regime of explicit health guarantees in Chile

Resumen: Objetivo: Describir la participación de los exámenes de imagen en el Régimen de Garantías Explícitas en Salud en Chile y analizar el papel de los radiólogos en este campo. Materiales y métodos: todas las patologías incluidas en el Programa de garantías explícitas en salud, cuentan con una guía de práctica clínica (GC) y un listado de prestaciones específicas (LP). Ambos fueron analizados respecto a la cantidad y la modalidad de los exámenes de imagen recomendados, la presencia de radiólogos dentro de los paneles de expertos y la concordancia entre las recomendaciones de las guías y los Listados de Prestaciones. Resultados: 60 GC (67%) y 55 LP (69%) incluyen pruebas de imagen dentro de sus prestaciones garantizadas. 7 GC (8%) recomiendan pruebas de imágenes no cubiertas en su listado de prestaciones respectivos y 5 pruebas de imágenes del LP (6%) no están incluídas en las guías clínicas. La participación de un radiólogo en el panel de expertos se asoció con la ausencia de discrepancias en las pruebas de imagen entre GC y LP (p = 0,007). Discusión: el diagnóstico por imágenes juega un papel importante dentro del Programa de garantías explícitas y se asocia al aumento de los costos de atención médica. Algunos casos de discordancia entre las guías clínicas y los Listados de Prestaciones representan costos económicos y sociales significativos que podrían reducirse al incluir radiólogos en los paneles de expertos, así como optimizar el uso de recursos y reducir la exposición de los pacientes a la radiación ionizante.

Abstract: Objective: To describe the involvement diagnostic imaging exams in the framework of Regime of Explicit Health Guarantees in Chile and analyze the role of radiologists in this field. Materials and methods: Every pathology included in the Explicit Healthcare Guarantees Program encompasses an expert consensus clinical guideline (CG) and a specific services list (SL). Both of them were analyzed regarding the amount and modality of imaging exams recommended, the presence of radiologists within the expert panels and the concordance between guidelines recommendations and service lists. Results: 60 CG (67%) and 55 SL (69%) include imaging tests within their guaranteed services. Seven CG (8%) recommend medical imaging tests not covered in their respective services list and 5 SL (6%) reference imaging tests not included in the clinical guidelines. The involvement of a radiologist on the expert panel was associated with the absence of imaging test discrepancies between CG and SL (p=0.007). Discussion: Diagnostic imaging plays an important role within the Explicit Healthcare Guarantees Program and is associated with rising healthcare costs. There are cases of discordance between clinical guidelines and specific services lists that account for significant economic and social costs, which may be reduced by including radiologists on expert panels, optimizing resource use and lowering patients' exposure to ionizing radiation.

Identifying Barriers to Building a Diverse Physician Workforce: A National Survey of the ACR Membership.

PURPOSE: The aim of this study was to identify potential barriers to building a diverse workforce in radiology and radiation oncology by conducting a national survey of physicians in these fields and studying their reported career experiences. METHODS: An electronic survey of ACR members (February 27, 2018, to April 26, 2018) was conducted in which physicians' attitudes about their work environment, relationships, and culture were queried. The aim was to determine if responses differed by gender or race/ethnicity. In total, 900 invitations were issued; women were oversampled with the goal of equal representation. Descriptive summaries (proportions of yes or no responses) were calculated per item, per subgroup of interest. Logistic regression analysis was used to identify significant associations between gender- and item-specific responses; it was not used in the race/ethnicity analysis because of the small sizes of many subgroups. RESULTS: The response rate was 51.2% (461 of 900). In total, 51.0% of respondents identified as women (235 of 461); the 9.5% (44 of 461) who identified as black or African American, Hispanic, or American Indian or Alaska Native were considered underrepresented minorities. Respondents' mean age was 40.2 ± 10.4 years. Subgroups varied most in their reporting of unfair or disrespectful treatment. Women were significantly more likely than men to report such treatment attributable to gender (50.6% versus 5.4%; odds ratio, 18.00; 95% confidence interval, 9.29-34.86; P < .001), and 27.9% of underrepresented minorities compared with 2.6% of white non-Hispanic respondents reported such treatment attributable to race/ethnicity. CONCLUSIONS: Women and underrepresented minorities disproportionately experience unfair or disrespectful treatment in the workplace. Addressing this problem is likely to be critically important for improving workforce diversity.

Geographic Variation in Gender Disparities in the US Radiologist Workforce.

PURPOSE: To assess geographic variation in gender disparities in the US radiologist workforce. METHODS: Gender, location, and practice affiliation of all radiologists and gender of all nonradiologists were identified for all providers listed in the Medicare Physician Compare database. Variation in female representation among radiologists was summarized at state, county, and individual practice levels, and associations with a variety of county-level population characteristics were explored. RESULTS: Nationally, 23.1% (7,501 of 32,429) of all radiologists were women versus 46.6% (481,831 of 1,034,909) of Medicare-participating nonradiologists. At the state level, female representation among radiologists was overall highest in the Northeast and Mid-Atlantic regions (Washington DC, 39.3%; Massachusetts, 34.3%; Maryland, 31.5%) and lowest in the West and Midwest (Wyoming, 9.0%; Montana, 10.7%; Idaho, 11.7%). At the county level, female representation varied from 0.0% to 100.0%, with weak positive correlations with county-level population (r = +0.39), median household income (r = +0.25), college education (r = +0.23), English nonproficiency (r = +0.21), mammography screening rates (r = +0.12), Democratic voting in the 2016 presidential election (r = +0.28), and weak negative correlation with county-level rural population percentage (r = -0.32). Among practices with ≥10 members, female representation varied greatly (0.0% to 100.0%). Female representation was higher among academic (32.3%) than nonacademic (20.6%) radiologists, and in states with higher female-to-male relative earnings (r = +0.556). CONCLUSION: Compared with nonradiologists, women are underrepresented in the national radiologist workforce. This underrepresentation is highly variable at state, county, and practice levels and is partially explained by a variety of demographic, socioeconomic, and political factors. These insights could help inform and drive initiatives to reduce gender disparities and more actively engage women in the specialty.

Associations of County-level Radiologist and Mammography Facility Supply with Screening Mammography Rates in the United States.

RATIONALE AND OBJECTIVES: The present study aims to assess associations of Medicare beneficiary screening mammography rates with local mammography facility and radiologist availability. MATERIALS AND METHODS: Mammography screening rates for Medicare fee-for-service beneficiaries were obtained for US counties using the County Health Rankings data set. County-level certified mammography facility counts were obtained from the United States Food and Drug Administration. County-level mammogram-interpreting radiologist and breast imaging subspecialist counts were determined using Centers for Medicare & Medicaid Services fee-for-service claims files. Spearman correlations and multivariable linear regressions were performed using counties' facility and radiologist counts, as well as counts normalized to counties' Medicare fee-for-service beneficiary volume and land area. RESULTS: Across 3035 included counties, average screening mammography rates were 60.5% ± 8.2% (range 26%-88%). Correlations between county-level screening rates and total mammography facilities, facilities per 100,000 square mile county area, total mammography-interpreting radiologists, and mammography-interpreting radiologists per 100,000 county-level Medicare beneficiaries were all weak (r = 0.22-0.26). Correlations between county-level screening rates and mammography rates per 100,000 Medicare beneficiaries, total breast imaging subspecialist radiologists, and breast imaging subspecialist radiologists per 100,000 Medicare beneficiaries were all minimal (r = 0.06-0.16). Multivariable analyses overall demonstrated radiologist supply to have a stronger independent effect than facility supply, although effect sizes remained weak for both. CONCLUSION: Mammography facility and radiologist supply-side factors are only weakly associated with county-level Medicare beneficiary screening mammography rates, and as such, screening mammography may differ from many other health-care services. Although efforts to enhance facility and radiologist supply may be helpful, initiatives to improve screening mammography rates should focus more on demand-side factors, such as patient education and primary care physician education and access.

A County-Level Analysis of the US Radiologist Workforce: Physician Supply and Subspecialty Characteristics.

PURPOSE: To explore associations between county-level measures of radiologist supply and subspecialization and county structural and health-related characteristics. METHODS: Medicare Physician and Other Supplier Public Use Files were used to subspecialty characterize 32,844 radiologists participating in Medicare between 2012 and 2014. Measures of radiologist supply and subspecialization were computed for 3,143 US counties. Additional county characteristics were identified using the 2014 County Health Rankings database. Mann-Whitney tests and Spearman correlations were performed. RESULTS: Counties with at least one (versus no) Medicare-participating radiologist had significantly (P < .001) larger populations (197,050 ± 457,056 versus 20,253 ± 23,689), lower rural percentages (39.5% ± 26.5% versus 74.6% ± 25.6%), higher household incomes ($47,608 ± $12,493 versus $42,510 ± $9,893), higher mammography screening rates (62.4% ± 7.0% versus 56.6% ± 15.3%), and lower premature deaths (7,581 ± 2,085 versus 7,784 ± 3,409 years of life lost). Counties' radiologists per 100,000 population and percent of subspecialized radiologists showed moderate positive correlations with counties' population (r = +0.505-+0.599) and moderate negative correlations with counties' rural percentage (r = -0.434 to -0.523). Radiologist supply and degree of subspecialization both showed concurrent positive or negative weak associations with counties' percent age 65+ (r = -0.256 to -0.271), percent Hispanic (r = +0.209-+0.234), and income (r = +0.230-+0.316). Radiologists per 100,000 population showed weak positive correlation with mammography screening (r = +0.214); percent of radiologists subspecialized showed weak negative correlation with premature death (r = -0.226). CONCLUSION: Geographic disparities in radiologist supply at the community level are compounded by superimposed variation in the degree of subspecialization of those radiologists. The potential impact of such access disparities on county-level health warrants further investigation.

Lung cancer screening-low dose CT for lung cancer screening: recent trial results and next steps.

Screening for lung cancer using low-dose CT has already been implemented in North America following the results of the National Lung Screening Trial. Outside North America, clinicians and researchers are addressing issues that may have a major impact on the success of screening programmes by reviewing results of existing trials and by designing new research and pilot programmes. This review summarizes the work that has been done to try to answer the remaining questions and highlights potential barriers which may affect screening uptake and cost-effectiveness.

Post Brexit: challenges and opportunities for radiology beyond the European Union.

We aimed to review the challenges and opportunities that radiology may face once the UK leaves the European Union (EU). Even before the exit negotiations commence, uncertainty over future policies and funding within the UK may influence the National Health Service (NHS). We discuss the potential impact that financial, regulatory and social changes may have on healthcare, and radiology in particular. Current difficulties in recruitment and retention of radiologists and the challenges that Brexit present are considered. Uncertainty over the new immigration regulations and their impact on the NHS workforce is addressed. Challenges also apply to UK research, which has greatly benefited from EU funding and the free movement of staff. Appreciating the problems as well as the opportunities that Brexit presents will help prepare radiology in the UK for the next decade.

Radiation therapy staffing model 2014.

INTRODUCTION: In 2001, the Radiation Therapy Advisory Panel (RTAP) of the Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) (formerly known as Australian Institute of Radiography) published a model for radiation therapist staffing in Australian radiation oncology departments. Between 2012-2013, the model was reviewed to ensure it reflected current radiation therapy practice, technology, and to facilitate forward planning of the radiation therapy workforce. METHOD: Twenty-four sites from all states participated and provided data on megavoltage simulation, planning and treatment delivery. For simulation and planning activity, the length of time to complete was collected against relevant Medicare Benefits Schedule (MBS) items. For treatment delivery, time to complete activities was collected against a common set of activities. Modelling assumptions are clearly identified in the methodology. RESULTS: A new model was developed retaining the essential model parameter of full-time equivalent (FTE) radiation therapists (RTs) per linear accelerator operating hour as in the 2001 model but based on contemporary practice and data. The model also includes significant refinements that improve the model's overall utility and flexibility for both workforce planning purposes and for individual services to use the model according to their own organisational needs and service delivery profiles. CONCLUSION: The ASMIRT believes that the 2014 RT staffing model provides the utility and flexibility for radiation oncology services to best plan RT staffing establishments according to their needs and reflecting the diversity between services and within the sector. It should also provide a robust and valid basis for governments and service planners to use as a guide in workforce planning into the future.

Supply/Demand in Radiology: A Historical Perspective and Comparison to other Labor Markets.

RATIONALE AND OBJECTIVES: There has been attention on the job market recently and on radiology's supply/demand calculus. Supply is influenced by the number of trained radiologists, while demand is driven by demographics and technological innovation. We analyze the supply of radiologists historically and compare to other labor markets-medical and non-medical, domestic and foreign. MATERIALS AND METHODS: We review National Resident Matching Program data in radiology and several other specialties from 1991 to 2015. We also review surveys, physician recruitment data, and peer-reviewed commentaries on medical specialty job markets. Trends are compared across specialties. The regulation of American medical training is compared to that in the United Kingdom and to a nonmedical labor market, unionized theatrical stage employees. RESULTS: Radiology residency positions have increased since 1998 despite a downturn in the job market. This expansion coincides with a decreasing percentage of positions filled by domestic graduates. A similar trend has been seen in pathology, a notoriously oversupplied specialty. Conversely, other specialties have maintained their proportion of domestic graduates by way of limited supply or implicit demand. CONCLUSIONS: The radiology job market is currently oversupplied, primarily a result of increasing residency positions despite indicators of decreasing demand. The percentage of residency positions filled by domestic graduates has decreased during the same period, suggesting that medical student interest is responsive to the market. Other specialties, particularly pathology, demonstrate the dangers of chronic oversupply. We advocate a reduction of radiology residency positions such that supply closely approximates demand without exceeding it. Additional measures may be taken, if necessary, to restore market equilibrium in the event of a mild undersupply.
