RESUMEN
Macrophages and dendritic cells (DCs), although ontogenetically distinct, have overlapping functions and exhibit substantial cell-to-cell heterogeneity that can complicate their identification and obscure innate immune function. In this study, we report that M-CSF-differentiated murine bone marrow-derived macrophages (BMDMs) exhibit extreme heterogeneity in the production of IL-12, a key proinflammatory cytokine linking innate and adaptive immunity. A microwell secretion assay revealed that a small fraction of BMDMs stimulated with LPS secrete most IL-12p40, and we confirmed that this is due to extremely high expression of Il12b, the gene encoding IL-12p40, in a subset of cells. Using an Il12b-YFP reporter mouse, we isolated cells with high LPS-induced Il12b expression and found that this subset was enriched for genes associated with the DC lineage. Single-cell RNA sequencing data confirmed a DC-like subset that differentiates within BMDM cultures that is transcriptionally distinct but could not be isolated by surface marker expression. Although not readily apparent in the resting state, upon LPS stimulation, this subset exhibited a typical DC-associated activation program that is distinct from LPS-induced stochastic BMDM cell-to-cell heterogeneity. Overall, our findings underscore the difficulty in distinguishing macrophages and DCs even in widely used in vitro murine BMDM cultures and could affect the interpretation of some studies that use BMDMs to explore acute inflammatory responses.

INTRODUCTION: Atrial fibrillation or flutter (AF) is a well-known risk factor for ischemic stroke. While female sex has been associated with higher stroke risk among AF patients, overall sex-specific real-world burdens of AF-related strokes and hemorrhages are unknown. METHODS: The 2016-2020 National Inpatient Sample was queried for hospitalizations, morbidity, and mortality due to AF-related ischemic strokes and bleeds. Patient demographic information, vascular risk factors, comorbidities, and stroke characteristics were extracted using ICD-10 codes. Overall incidences were calculated using total population estimates provided by the United States Census Bureau, and relative risk was calculated by comparing annual incidences between men and women. RESULTS: 2,420,870 ischemic stroke hospitalizations were identified; 542,635 (22.4%) were associated with AF. Overall, women had similar risk of hospitalization due to AF-related ischemic strokes compared to men; however, women had a higher risk of morbidity and mortality (RR 1.13 and 1.17, respectively; both p<0.001). In contrast, women had lower incidences of hospitalization, morbidity, and mortality due to AF-related bleeds (RR 0.82, 0.94, and 0.74, respectively; all p<0.001). Among patients with AF-related ischemic strokes, women had lower rates of anticoagulation use, higher rates of large vessel occlusion, and higher stroke severity (all p<0.001). These trends persisted among patients 80 years or older (all p<0.001). CONCLUSION: Women in the United States have higher incidences of morbidity and mortality from AF-related ischemic strokes than men. Future studies should investigate strategies to reduce morbidity and mortality due to AF-related strokes in women.
RESUMEN
BACKGROUND: Osteoarthritis and other musculoskeletal disorders are the leading causes of disability in the United States. While osteoarthritis is not a direct risk factor for stroke, osteoarthritis may impact patient selection for endovascular thrombectomy (EVT) due to prestroke disability. This study investigates associations of osteoarthritis with EVT utilization and outcomes. METHODS: This was a large-scale cross-sectional study of the 2016 to 2019 National Inpatient Sample database. Adult patients with anterior large vessel ischemic strokes were identified. Patient demographics, stroke risk factors, stroke etiology, presence of osteoarthritis, medical comorbidities, EVT, intravenous thrombolysis treatments, and discharge destinations were recorded. Primary outcome was the rate of EVT treatment. Secondary outcomes include rates of discharge to home and in-hospital mortality. Propensity score matching and multivariable logistic regression models were used to account for possible confounders. RESULTS: Two hundred fifty-two thousand five hundred five patients were identified, of whom 8.5% (21 500 patients) had osteoarthritis. After propensity score matching for 32 clinical variables, osteoarthritis patients were found to be 17.3% less likely to receive EVT than non-osteoarthritis patients (14.4% versus 17.3%, respectively; P<0.001). In multivariable logistic regression analysis, osteoarthritis was associated with 22.6% lower odds of receiving EVT (OR, 0.77 [95% CI, 0.70-0.86]; P<0.001), an effect size larger than any medical comorbidity captured in this study other than dementia and nonstroke neurological disease. Among those treated with EVT, multivariable logistic regression models showed that osteoarthritis was not associated with different odds of being discharged home (OR, 0.99 [95% CI, 0.81-1.21]; P=0.93); however, osteoarthritis was marginally associated with lower odds of in-hospital mortality (OR, 0.74 [95% CI, 0.54-1.01]; P=0.054). CONCLUSIONS: Large vessel ischemic stroke patients with osteoarthritis were significantly less likely to receive EVT therapy despite similar post-EVT outcomes. These results warrant further investigation and prompt a critical review of current patient selection practices for stroke EVT therapy, specifically for patients with baseline disability due to musculoskeletal conditions such as osteoarthritis.

Background Radiology ranks high in terms of specialties implicated in medical malpractice claims. While most radiologists understand the risks of liability for missed findings or lapses of communication, liability for the use of contrast agents in imaging procedures may be underappreciated. Purpose To review the clinical context and outcomes of lawsuits alleging medical malpractice for contrast-related imaging procedures. Materials and Methods Two large U.S. legal databases were queried using the terms "Contrast" and "Radiology OR Radiologist" from database inception to October 31, 2022, to identify cases with published decisions or settlements related to medical malpractice in patients who underwent contrast-related imaging procedures. The search results were screened to include only those cases involving the practice area of health care law where there was at least one claim of medical negligence against a health care institution or provider. Data on the medical complications alleged by patients after contrast agent administration and on the trial were extracted and reported using descriptive statistics. Results A total of 151 published case summaries were included in the analysis. Anaphylactic reaction following contrast agent administration was the most common medical complication observed (30% [45 of 151 cases]), of which failure to diagnose developing anaphylaxis or failure to treat the anaphylactic reaction made up the majority of allegations (93% [42 of 45]). Inappropriate management of contrast media extravasation (27% [41 of 151]) and alleged contrast agent-induced acute kidney injury (13% [19 of 151]) were the next most frequent causes of lawsuits. Of the 11 cases of alleged kidney injury that went to trial, all resulted in a judgment in favor of the defense. Conclusion This study highlights the key reasons for medical malpractice lawsuits associated with use of contrast media and outcomes from these lawsuits. © RSNA, 2023 Supplemental material is available for this article.

INTRODUCTION: Endovascular treatment (EVT) is a therapeutic option for cerebral venous thrombosis (CVT); however, its benefit over conservative medical management has not been proven. Whether current patient selection practices are appropriate for EVT is unclear. METHODS: This was a nationwide study of the 2016-2020 National Inpatient Sample database. Adult CVT patients and EVT treatments were identified. Patient demographics, medical comorbidities, CVT risk factors, and CVT manifestations were identified. Presence of radiographic signs of advanced and severe CVT (venous infarction, cerebral edema, and intracranial hemorrhage) were recorded. Primary and secondary outcomes were good discharge outcomes and in-hospital mortality, respectively. RESULTS: 17,130 CVT patients were identified, and 56.7% had good discharge outcomes while 4.6% died during hospitalization. 945 (5.5%) received EVT, and EVT patients were more likely to have cerebral infarction (35.4% vs. 21.8%, p<0.001), edema (35.4% vs. 20.1%, p<0.001), and hemorrhage (37.6% vs. 19.7%, p<0.001). After multivariable adjustments, EVT for patients without infarction, edema, or hemorrhage was moderately associated with higher odds of good outcomes (OR 1.86 [95%CI 0.98 - 3.53], p=0.059) and resulted in zero deaths. However, with increasing burden of radiographic signs of advanced CVT measured by the cumulative presence of infraction, edema, and hemorrhage, EVT was associated with decreasing odds of good outcomes and increasing odds of in-hospital mortality compared to medical management (interaction p=0.046 and 0.029, respectively). CONCLUSIONS: EVT may lead to higher rates of favorable hospitalization outcomes in patients who have not yet developed overt parenchymal manifestations of backpressure changes; presence of infarction, edema, and hemorrhage may diminish the short-term effectiveness of EVT.
RESUMEN
INTRODUCTION: We evaluated trends in Medicare reimbursement for common gastrointestinal (GI) services from 2007 to 2022. METHODS: Top GI procedures and office/inpatient visits were identified. The Physician Fee Schedule Look-Up Tool from Centers for Medicare & Medicaid Services was queried to extract reimbursement data. Reimbursement trends were analyzed, accounting for inflation. RESULTS: GI procedures exhibited an average decrease in unadjusted and adjusted reimbursement of 7.0% and 33.0%, respectively. Reimbursement for patient visits exhibited an inflation-adjusted decrease of 4.9%. DISCUSSION: The analysis revealed a steady decline in adjusted reimbursement for both GI procedures and patient visits in the past 15 years.

Background There have been growing efforts nationally and institutionally toward diversity in radiology. Purpose To analyze sex and racial and ethnic diversity over time (2010-2019) for the various levels of the U.S. academic radiology physician workforce in context of the available pipeline of medical students and trainees. Materials and Methods Data on sex and race and ethnicity were collected among medical school applicants, graduates, radiology residency applicants, residents, and different levels of academic radiology faculty. All trainee data were obtained from two time points, 2010-2011 and 2019-2020. Radiology faculty data were collected from 2010 to 2019. The sex and racial and ethnic composition at each academic level was compared between 2010 and 2019 using the χ2 test and a significance level of P < .05. Results In 2019, the percentage of female faculty among radiology instructors was 38% (251 of 655); assistant professors, 31% (1503 of 4801); associate professors, 28% (600 of 2161); professors, 22% (424 of 1901); and department chairs, 17% (37 of 220). The proportion of female faculty increased from 2010 to 2019, with the greatest relative increase in percentages among the more senior faculty positions. However, the proportion of female department chairs has only increased from 13% (27 of 203) in 2010 to 17% (37 of 220) in 2019. Across training levels, the most abrupt change in composition of female trainees occurred from medical school matriculates (52%, 11 160 of 21 614) to radiology residency applicants (29%, 656 of 2274), which largely stayed unchanged from 2010 to 2019. The proportion of Black or African American department chairs was 5% (10 of 220) in 2019, which was higher compared with that of assistant professor, associate professor, and professor levels for Black or African American faculty (3% [130 of 4949], 2% [41 of 2208], and 2% [35 of 1924], respectively), with proportions of Hispanic faculty at 5% (240 of 4949), 4% (96 of 2208), and 3% (60 of 1924), respectively. These proportions have not changed since 2010. Conclusion Identifying and addressing reasons for the low proportion of female radiology residency applicants despite a highly diverse pool of medical students would be key to increasing female representation in the field. The low representation of African American and Hispanic individuals in academic radiology is seen at all levels and has not changed much over time. Efforts to increase diversity may need to be focused toward the medical school and residency application levels. © RSNA, 2022 Online supplemental material is available for this article.

OBJECTIVE: The objective of this study was to examine the published cost-effectiveness analyses (CEAs) on endovascular thrombectomy (EVT) in acute stroke patients, with a particular focus on the practice of accounting for costs and utilities. METHODS: We conducted a systematic review of published CEAs on EVT in acute stroke patients from 1/1/2009 to 10/1/2019. Published CEAs were searched in Ovid Embase, Ovid MEDLINE, and Web of Science. Cost or comparative effectiveness analyses were excluded. Risk of bias and quality assessment was based on the Consolidated Health Economic Evaluation Reporting Standard checklist. RESULTS: Twenty-one studies were included in the final analysis, from the USA, Canada, Europe, Asia, and Australia. They all concluded EVT to be cost-effective, but with significant variations in methodology. Fifteen studies employed a long-term horizon (> 20 years), while only 11 incorporated risk of recurrent strokes. The willingness-to-pay (WTP) threshold varied from $10,000/quality-adjusted life year (QALY) to $120,000/QALY, with $50,000/QALY and $100,000/QALY being the most commonly used. Five studies undertook a societal perspective, but only one accounted for indirect costs. Seventeen studies based outcomes on 90-day modified Rankin Scale (mRS) scores, and 9 of these 17 studies grouped outcomes by mRS 0-2 and 3-5. Among these 9 studies, the range of QALY score reported for mRS 0-2 was 0.71-0.85 QALY, and that of mRS 3-5 was 0.21-0.40. CONCLUSIONS: Our study reveals significant heterogeneity in previously published thrombectomy CEAs, highlighting need for better standardization in future CEAs. KEY POINTS: ⢠All included studies concluded thrombectomy to be cost-effective, from both long- and short-term perspectives. ⢠Only 5 out of 22 studies undertook a societal perspective, and only 1 accounted for indirect costs. ⢠The range of value for mRS 0-2 was 0.71-0.85 quality-adjusted life year (QALY) and 0.21-0.40 QALY for mRS 3-5.

BACKGROUND AND OBJECTIVES: There is a paucity of high-level evidence for endovascular thrombectomy (EVT) in posterior cerebral artery (PCA) strokes. METHODS: The MEDLINE, Embase, and Web of Science databases were queried for well-conducted cohort studies comparing EVT vs medical management (MM) for PCA strokes. Outcomes of interest included 90-day functional outcomes, symptomatic intracranial hemorrhage (sICH), and death. The level of evidence was determined per the Oxford Centre for Evidence-Based Medicine criteria. We also conducted a propensity score matched (PSM) analysis of the 2016-2020 National Inpatient Sample (NIS) to provide support for our findings with real-world data. RESULTS: A total of 2,095 patients (685 EVT and 1,410 MM) were identified across 5 well-conducted cohort studies. EVT was significantly associated with higher odds of no disability at 90 days (odds ratio [OR] 1.25, 95% CI 1.04-1.50, p = 0.015) but not functional independence (OR 0.87, 95% CI 0.72-1.07, p = 0.18). EVT was also associated with higher odds of sICH (OR 2.48, 95% CI 1.55-3.97, p < 0.001) and numerically higher odds of death (OR 1.32, 95% CI 0.73-2.38; p = 0.35). PSM analysis of 95,585 PCA stroke patients in the NIS showed that EVT (n = 1,540) was associated with lower rates of good discharge outcomes (24.4% vs 30.7%, p = 0.037), higher rates of in-hospital mortality (8.8% vs 4.9%, p = 0.021), higher rates of ICH (18.2% and 11.7%, p = 0.008), and higher rates of subarachnoid hemorrhage (3.9% vs 0.6%, p < 0.001). Among patients with moderate to severe strokes (NIH Stroke Scale 5 or greater), EVT was associated with significantly higher rates of good outcomes (21.7% vs 13.8%, p = 0.023) with similar rates of mortality (7.6% vs 6.6%, p = 0.67) and ICH (17.8% vs, 13.1%, p = 0.18). DISCUSSION: Our meta-analysis revealed that while EVT may be effective in alleviating disabling deficits due to PCA strokes, it is not associated with different odds of functional independence and may be associated with higher odds of sICH. These findings were corroborated by our large propensity score matched analysis of real-world data in the United States. Thus, the decision to pursue PCA thrombectomies should be carefully individualized for each patient. Future randomized trials are needed to further explore the efficacy and safety of EVT for the treatment of PCA strokes. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that in patients with acute PCA ischemic stroke, treatment with EVT compared with MM alone was associated with higher odds of no disabling deficit at 90 days and higher odds of sICH.

BACKGROUND AND PURPOSE: The efficacy and safety of endovascular thrombectomy (EVT) for elderly basilar artery occlusion (BAO) stroke patients is unclear. MATERIALS AND METHODS: This was an explorative retrospective analysis of the 2016-21 National Inpatient Sample in the United States. Elderly BAO stroke patients (80 years or older) with NIH stroke scale of at least 5 were included. Primary outcome was discharge to home. Secondary outcomes include in-hospital mortality and intracranial hemorrhage (ICH). Outcomes were compared between patients treated with EVT and those treated with medical management (MM) alone. Propensity score matching (PSM) was performed to control for confounders. Subgroup analyses were conducted for patients who did and did not receive intravenous thrombolysis (IVT). RESULTS: 2,520 elderly BAO patients were identified; 830 received EVT, and 1,690 received MM alone. After PSM, 1,115 patients and 715 patients remained in the MM and EVT groups, respectively. Compared to PSM controls, EVT was not significantly associated with different rates of home discharge (17.5% vs. 12.2%, OR 1.36 [95%CI 0.76-2.44], p=0.30) or in-hospital mortality (31.5% vs. 32.9%, OR 1.00 [95%CI 0.63-1.60], p=0.99), but it was significantly associated with higher rates of ICH (18.2% vs. 7.3%, OR 2.69 [95%CI 1.41- 5.15], p=0.003). Among patients who did not receive IVT, EVT was significantly associated with higher rates of home discharge (21.5% vs. 11.5%, OR 1.93 [95%CI 1.02-3.66], p=0.044), whereas EVT was not significantly associated with the same among those treated with IVT (5.6% vs. 15.0%, OR 0.28 [95%CI 0.05-1.46], p=0.13). Interaction analysis revealed that IVT was a negative modulator of EVT's positive association with home discharge (interaction p=0.031). CONCLUSIONS: EVT was not significantly associated with more favorable hospitalization outcomes for elderly BAO stroke patients, and it was significantly associated with increased risk of ICH. EVT may be an effective treatment for patients who did not receive IVT. ABBREVIATIONS: EVT = endovascular thrombectomy; BAO = basilar artery occlusion; ICH = intracranial hemorrhage; MM = medical management; PSM = propensity score matching; IVT = intravenous thrombolysis.
RESUMEN
BACKGROUND: There are no established patient selection criteria for endovascular thrombectomy (EVT) for anterior cerebral artery (ACA) stroke. METHODS: This was a retrospective cohort study of the 2016-2020 National Inpatient Sample in the United States. Isolated ACA-occlusion stroke patients with moderate-to-severe stroke symptoms (NIH stroke scale [NIHSS] ≥ 6) were included. Primary outcome was hospital discharge to home with self-care. Secondary outcomes include in-hospital mortality and intracranial hemorrhage (ICH). Confounders were accounted for by multivariable logistic regression. RESULTS: 6685 patients were included; 335 received EVT. Compared to medical management (MM), EVT patients were younger (mean 67.2 versus 72.2 years; p = 0.014) and had higher NIHSS (mean 16.0 versus 12.5; p < 0.001). EVT was numerically but not statistically significantly associated with higher odds of home discharge compared to MM (aOR 2.26 [95%CI 0.99-5.17], p = 0.053). EVT was significantly associated with higher odds of home discharge among patients with NIHSS 10 or greater (aOR 3.35 [95%CI 1.06-10.58], p = 0.039), those who did not receive prior thrombolysis (aOR 3.96 [95%CI 1.53-10.23], p = 0.005), and those with embolic stroke etiology (aOR 4.03 [95%CI 1.21-13.47], p = 0.024). EVT was not significantly associated with higher rates of mortality (aOR 1.93 [95%CI 0.80-4.63], p = 0.14); however, it was significantly associated with higher rates of ICH (22.4% vs. 8.5%, p < 0.001). CONCLUSION: EVT was associated with higher odds of favorable short-term outcomes for moderate-to-severe ACA-occlusion stroke in select patients. Future studies are needed to confirm the efficacy of EVT in terms of longer term neurological outcomes.

PURPOSE: The nature of lawsuits involving interventional radiologists (IRs) is not well understood. The purposes of this article are to provide an overview of the causes of action underlying medical malpractice lawsuits related to IRs and to characterize the associated factors and outcomes. METHODS: Two large legal databases were used to search for US legal cases in which there were jury awards and settlements involving IRs in the United States. Cases were screened to include only those cases in which the cause of action involved negligence on the part of IRs. RESULTS: A total of 389 published case summaries were identified, of which 93 were eligible to be included in the analysis. In 46% of the cases (43 of 93), medical malpractice was alleged against an individual IR, whereas in 43% (40 of 93), it was alleged against both an individual IR and a health care institution. Thirty-five percent of IR malpractice cases (33 of 93) involved the performance of a vascular procedure, most commonly embolization procedures (30% [n = 10]), stenting or angioplasty (21% [n = 7]), and diagnostic arteriography and angiography (18% [n = 6]). Twenty-six percent of cases (24 of 93) involved IR performance of a biopsy. Eighteen percent of cases (17 of 93) involved a failure to gain informed consent in addition to an allegation of medical negligence during treatment. Eleven percent of cases (10 of 93) were resolved by settlement, with an average settlement amount of $877,500 (range, $200,000-$2,700,000). Among the 72 cases that went to trial, 74% (53 of 72) resulted in judgments for the defendants, and 26% (19 of 72) resulted in judgements for the plaintiffs, with an average award of $2,012,243 (range, $101,667-$6,400,000). CONCLUSIONS: Vascular procedures and biopsies were the most frequent reasons for malpractice lawsuits involving IRs. Failure to gain informed consent in addition to an allegation of medical negligence during treatment was not infrequent. Although the majority of published medical malpractice claims involving IRs resulted in judgments in favor of the defendants, the average amount awarded to plaintiffs was higher compared with previous data reported for all physicians.

BACKGROUND: The accuracy and completeness of self-disclosures by authors of imaging guidelines are not well known. OBJECTIVE: The aim of this study was to assess the accuracy of financial disclosures by US authors of ACR appropriateness criteria. METHODS: We reviewed financial disclosures provided by US-based authors of all ACR-AC published in 2019, 2021 and 2023. For each US- based author, payment reports were extracted from the Open Payments Database (OPD) in the previous 36 months related to general category and research payments categories. We analyzed each author individually to determine if the reported disclosures matched results from OPD. RESULTS: A total of 633 authorships, including 333 unique authors were included from 38 ACR AC articles in 2019, with 606 authorships (387 unique authors) from 35 ACR-AC articles published in 2021, and 540 authorships (367 unique authors) from 32 ACR AC articles published in 2023. Among authors who received industry payments, failure to disclose any financial relationship was seen in 125/147 unique authors in 2019, 142/148 authors in 2021 and 95/125 unique authors in 2023. The proportion of nondisclosed total value of payments was 86.1% in 2019, 88.6% in 2021 and 56.7% in 2023. General category payments were nondisclosed in 94.1% in 2019, 89.7% in 2021 and 94.4% in 2023 by payment value. CONCLUSION: Industry payments to authors of radiology guidelines are common and frequently undisclosed.

BACKGROUND: Equity in faculty compensation in U.S. academic radiology physicians relative to other specialties is not well known. OBJECTIVE: The aim of this study is to assess salary equity in U.S. academic radiology physicians at different ranks relative to other clinical specialties. METHODS: The American Association of Medical Colleges (AAMC) Faculty Salary Survey was used to collect information for full-time faculty at U.S. medical schools. Financial compensation data were collected for 2023 for faculty with MD or equivalent degree in medical specialties, stratified by gender and rank. RESULTS: The AAMC Faculty Salary Survey data for 2023 included responses for 97,224 faculty members in clinical specialties, with 5847 faculty members in Radiology departments. In radiology, compared to men (n = 3839), the women faculty members (n = 1763) had a lower median faculty compensation by 6% at the rank of Assistant Professor, 3% for Associate Professors, 4% for Professors and 6% for Section Chief positions. Surgery had the highest difference in median compensation with 21%, 24%, 22% and 19% lower faculty compensation, respectively, for women faculty members at corresponding ranks. Pathology had the lowest percent difference (<1%) in median compensation for all professor ranks. Salary inequity in radiology was lower compared to most other specialties. From assistant to full professors, all other clinical specialties except Pathology and Psychiatry, had a greater salary inequity than Radiology. CONCLUSION: The salary inequity in academic radiology faculty is lower than most other specialties. Further efforts should be made to reduce salary inequities as broader efforts to provide a more diverse, equitable and inclusive environment. SUMMARY STATEMENT: Salary inequity in academic radiology faculty is lower than most other specialties.

PURPOSE: To identify characteristics of interventional radiologists receiving more than $100,000 in general industry payments over a 5-year period (2017-2021). METHODS: The Open Payments database was queried to identify interventional radiologists who received more than $100,000 in consulting fees, speaker fees, education, and/or gifts over a 5-year period from 2017 to 2021. The national provider identifier registry, Scopus, and a web-based search were used to identify physician characteristics, such as demographics, research profile, leadership positions, and social media presence. RESULTS: From 2017-2021, 125 interventional radiologists received cumulative payments greater than $100,000 in consulting fees, speaker fees, education, and gifts. For this subset of physicians, the median (IQR) cumulative payment value was $214,380 ($141,812 - $383,740), and the total payment value was $40 million. While the highest-paid subset of physicians represented only 3 % (125/4272) of all US interventional radiologists paid by industry, the total payment value represented 66 % ($40,039,610.08/$60,859,025) of the total payment value among all interventional radiologists. 47 % (59/125) had faculty appointments and 30 % (37/125) had hospital leadership positions. 22 % (27/125) were clinical practice guideline authors, while 18 % (23/125) served on journal editorial boards and 12 % (15/125) had positions in specialty association leadership. Castle Connolly recognized 26 % (32/125) as top doctors. Among the 96 % (120/125) with published research in the past 5 years, the median (IQR) H-index was 17 (7-31). 38 % (48/125) had a presence on Twitter with a median (IQR) Kardashian index of 2.03 (0.48-6.16). CONCLUSION: A small subset of interventional radiologists receive large payments from drug and medical device companies. These physicians are leaders in their field with influence in hospitals, research, associations, and social media. Further work is needed to understand how the concentration of these payments affects decisions in clinical practice and policy.
RESUMEN
BACKGROUND: The impact of intersectionality on academic radiology physician compensation is not well known. PURPOSE: The aim of this study was to assess impact of intersectionality on academic radiology financial compensation, based on rank, gender and race/ethnicity in US medical schools. METHODS: Data were collected from the AAMC Faculty Salary Survey, which collects information for full-time faculty at U.S. medical schools. Financial compensation data for radiology faculty with MD or equivalent degree in diagnostic radiology (DR) as well as interventional radiology (IR) was collected for 2023, stratified by rank, gender, and race/ethnicity. RESULTS: The AAMC Faculty Salary Survey data for 2023 included responses for 683 IR (138 women, 545 men) and 2431 DR (862 women, 1569 men) faculty. Men had a higher median compensation than women at all ranks, for both IR and DR, except DR instructors. The gender pay gap was greater in IR faculty compared to DR faculty of the same rank. All intersectional groups among IR faculty reported a lower median compensation compared to White men of the same rank. All intersectional groups among DR faculty, except Asian Men, had a lower median compensation than White men of the same rank. Among IR faculty, Asian women assistant professors faced the greatest disparity in median compensation, down to $75 K (15%) lower than White men. Among DR faculty, Black/African American women assistant professors faced the greatest disparity on median compensation, down to $48 K (10.5%) lower than White men. CONCLUSION: The study results raise important concerns about impact of intersectionality on faculty compensation in radiology which needs further study and should be addressed as part of broader drive to increase diversity, equity, and inclusion in academic radiology.
