Untapped Resources: Attaining Equitable Representation for Women in IR.

PURPOSE: To investigate the current state of gender diversity among invited coordinators at the Society of Interventional Radiology (SIR) Annual Scientific Meeting and to compare the academic productivity of female interventional radiologists to that of invited male coordinators. MATERIALS AND METHODS: Faculty rosters for the SIR Annual Scientific Meetings from 2015 to 2017 were stratified by gender to quantify female representation among those asked to lead and coordinate podium sessions. To quantify academic productivity and merit, H-index, publications, and authorship by females over a 6-year period (2012-2017) were statistically compared to that of recurring male faculty. RESULTS: From 2015 to 2017, women held 7.1% (9/126), 4.3%, (8/188), and 13.7% (27/197) of the available coordinator positions for podium sessions, with no representation at the plenary sessions, and subject matter expertise was concentrated in economics and education. Academic productivity of the top quartile of published female interventional radiologists was statistically similar to that of the invited male faculty (H-index P = .722; total publications P = .689; and authorship P = .662). CONCLUSIONS: This study found that senior men dominate the SIR Annual Scientific Meeting, with few women leading or coordinating the podium sessions, despite their established academic track record.

Neurointerventional Radiology for the Aspiring Radiology Resident: Current State of the Field and Future Directions.

OBJECTIVE: The purposes of this study were to document recent trends in stroke intervention at a tertiary-care facility with a comprehensive stroke center and to analyze current procedure volumes and the employment of specialty providers in neurointerventional radiology (NIR). MATERIALS AND METHODS: Institutional trends in the volume of mechanical thrombectomy were analyzed on the basis of the number of patients who underwent mechanical thrombectomy from 2013 to 2017. To evaluate the current status of mechanical thrombectomy volumes in the United States, the number of patients in the Medicare fee-for-service database who underwent mechanical thrombectomy in 2016 was assessed. The specialty backgrounds of the various providers who performed mechanical thrombectomy were analyzed. Procedure volumes for intracranial stenting, embolization, and vertebral augmentation procedures were assessed. RESULTS: From 2013 to 2017, the total numbers of mechanical thrombectomy procedures for acute ischemic stroke were 19 in 2013 and 111 in 2017. The total volume of mechanical thrombectomy procedures in the Medicare fee-for-service population in 2016 was 7479. For intracranial endovascular procedures, 20,850 were performed in the U.S. Medicare population in 2015 and 22,511 in 2016. Radiologists performed 45% of procedures in 2016; neurosurgeons, 41%; and neurologists, 11%. When the total numbers of percutaneous brain and spine procedures were combined, radiologists performed 41%; neurosurgeons, 23%; and neurologists, 3%. In 2016, there were a total of 220 active NIR staff at the NIR programs with rotating residents or fellows. In these programs, 49% of staff members were neuroradiologists, 41% were neurosurgeons, and 10% were neurologists. Of the 72 NIR departments with confirmed rotating fellows or residents, 14 had only neuroradiologists on staff, six had only neurosurgeons, and one had only neurologists. CONCLUSION: Increasing radiology resident interest and participation in NIR should ensure a steady influx of radiologists into the field, continuing the strong tradition of radiology participation, leadership, and innovation in NIR.

Characterizing the Impact of Women in Academic IR: A 12-Year Analysis.

PURPOSE: To determine the representation of female interventional radiology (IR) investigators and elucidate possible gender-specific disparities. MATERIALS AND METHODS: We analyzed 4,884 original, peer-reviewed articles from 2006-2017 in the Journal of Vascular and Interventional Radiology and CardioVascular and Interventional Radiology. Data abstraction and statistical analysis were performed for first and senior author gender, citations, and grants. RESULTS: We found that 84% of first authors and 91.4% of senior authors were male (P < .01). No significant difference was observed versus expected in terms of author gender collaboration combinations (P = 1.00). Each year reflected a 0.3%-0.4% increase in articles published by women (first author: B-value: 0.3, P = .05; senior author: B-value: 0.4, P = .01). No difference was observed in citations or grants received between genders. Female authors received increasing citations and grants each year (citations: first author: B-value: 0.24, P = .05; senior author: B-value: 0.16, P = .15; grants: B-value: 0.88, P = .02). CONCLUSIONS: Women are equally as productive as men as determined by metrics such as number of publications, citations, and grants and are proportionally represented in the literature. No data indicating collaborative or citation/grant discrimination were observed, suggesting that the academic IR community is inclusive of its female constituents and equally respects their research contributions. Based on the statistically significant increases in female authorship observed in this 12-year study, this article reports encouraging trends for the future of women in interventional radiology.

Outside the operating room: How a robotics program changed resource utilization on the inpatient Ward.

OBJECTIVE: To analyze the changes in the composition of the gynecologic oncology inpatient ward following the implementation of a robotic surgery program and its impact on inpatient resource utilization and costs. METHODS: Retrospective review of the medical charts of patients admitted onto the gynecologic oncology ward the year prior to and five years after the implementation of robotics. The following variables were collected: patient characteristics, hospitalization details (reason for admission and length of hospital stay), and resource utilization (number of hospitalization days, consultations, and imaging). RESULTS: Following the introduction of robotic surgery, there were more admissions for elective surgery yet these accounted for only 21% of the inpatient ward in terms of number of hospital days, compared to 36% prior to the robotic program. This coincided with a sharp increase in the overall number of patients operated on by a minimally invasive approach (15% to 76%, p<0.0001). The cost per surgical admission on the inpatient ward decreased by 59% ($9827 vs. $4058) in the robotics era. The robotics program contributed to a ward with higher proportion of patients with complex comorbidities (Charlson≥5: RR 1.06), Stage IV disease (RR 1.30), and recurrent disease (RR 1.99). CONCLUSION: Introduction of robotic surgery allowed for more patients to be treated surgically while simultaneously decreasing inpatient resource use. With more patients with non-surgical oncological issues and greater medical complexity, the gynecologic oncology ward functions more like a medical rather than surgical ward after the introduction of robotics, which has implications for hospital-wide resource planning.

Underrepresentation of Women and Minorities in the United States IR Academic Physician Workforce.

PURPOSE: To assess the United States interventional radiology (IR) academic physician workforce diversity and comparative specialties. METHODS: Public registries were used to assess demographic differences among 2012 IR faculty and fellows, diagnostic radiology (DR) faculty and residents, DR subspecialty fellows (pediatric, abdominal, neuroradiology, and musculoskeletal), vascular surgery and interventional cardiology trainees, and 2010 US medical school graduates and US Census using binomial tests with .001 significance level (Bonferroni adjustment for multiple comparisons). Significant trends in IR physician representation were evaluated from 1992 to 2012. RESULTS: Women (15.4%), blacks (2.0%), and Hispanics (6.2%) were significantly underrepresented as IR fellows compared with the US population. Women were underrepresented as IR (7.3%) versus DR (27.8%) faculty and IR fellows (15.4%) versus medical school graduates (48.3%), DR residents (27.8%), pediatric radiology fellows (49.4%), and vascular surgery trainees (27.7%) (all P < .001). IR ranked last in female representation among radiologic subspecialty fellows. Blacks (1.8%, 2.1%, respectively, for IR faculty and fellows); Hispanics (1.8%, 6.2%); and combined American Indians, Alaska Natives, Native Hawaiians, and Pacific Islanders (1.8%, 0) showed no significant differences in representation as IR fellows compared with IR faculty, DR residents, other DR fellows, or interventional cardiology or vascular surgery trainees. Over 20 years, there was no significant increase in female or black representation as IR fellows or faculty. CONCLUSIONS: Women, blacks, and Hispanics are underrepresented in the IR academic physician workforce relative to the US population. Given prevalent health care disparities and an increasingly diverse society, research and training efforts should address IR physician workforce diversity.

Utility of simultaneous interventional radiology and operative surgery in a dedicated suite for seriously injured patients.

PURPOSE OF REVIEW: In recent years, combined interventional radiology and operative suites have been proposed and are now becoming operational in select trauma centres. Given the infancy of this technology, this review aims to review the rationale, benefits and challenges of hybrid suites in the management of seriously injured patients. RECENT FINDINGS: No specific studies exist that investigate outcomes within hybrid trauma suites. Endovascular and interventional radiology techniques have been successfully employed in thoracic, abdominal, pelvic and extremity trauma. Although the association between delayed haemorrhage control and poorer patient outcomes is intuitive, most supporting scientific data are outdated. The hybrid suite model offers the potential to expedite haemorrhage control through synergistic operative, interventional radiology and resuscitative platforms. Maximizing the utility of these suites requires trained multidisciplinary teams, ergonomic and workplace considerations, as well as a fundamental paradigm shift of trauma care. This often translates into a more damage-control orientated philosophy. SUMMARY: Hybrid suites offer tremendous potential to expedite haemorrhage control in trauma patients. Outcome evaluations from trauma units that currently have operational hybrid suites are required to establish clearer guidelines and criteria for patient management.

Demographic development leads to an exponential increase of cardiovascular illness. Additionally, technical development of conservative and invasive treatment modalities adds to an increase of specified therapy. Both items lead to increased specialization and a new orientation of vascular specialties. This concept implies that specific contents are referred and contained to the partner specialties. Angiology, vascular surgery and radiology are primary partners in this concept, however, in the following article the focus lies on vascular surgery and radiology.

Training in endovascular surgical neuroradiology.

BACKGROUND: During the past few years, the field of endovascular surgical neuroradiology has been expanding. Neurosurgeons, radiologists, and neurologists are currently being trained. We analyzed data from a national survey of endovascular training programs to assess the current training status and future projections. METHODS: Survey participation requests were sent out to program directors and members of the Society of Endovascular Neurosurgery, the Society of Neurointerventional Surgery, and the Society of Vascular and Interventional Neurology. The format was an on-line survey designed by the authors, and completed through the SurveyMonkey.com website. Forty-three programs were identified and invited to participate. RESULTS: We achieved a response rate of 81% (n = 35). Twenty-seven (79%) of the 35 respondents listed their training program as academic, and 7 (20%) listed it as a mixture of academic with private practice. The training program faculty consisted of 57 radiologists, 39 neurosurgeons, and 10 neurologists. Length of fellowship offered was the same for all specialties in 43%, and differed based on clinical experience/background in 51%. Of the programs, 86% offered a 2-year fellowship, 49% had a mandatory resident rotation, 17% offered an infolded complete fellowship for residents, and 34% offered an infolded partial fellowship. Only 9% reported no resident exposure at all. There were 12% of respondents who reported to have knowledge of vascular surgeons or cardiologists performing intracranial procedures. At the time of the survey, there were 68 fellows in training, and most entered training immediately after residency (38%), whereas 26% entered after a fellowship and another 26% trained while in residency. There will be a 14% increase of graduates within the next 5 years. Comparing the past 5 years (2003-2007) with future 5-year projections (2008-2012), the number of radiologists is declining by 37% (73 vs. 46), whereas the number of neurosurgeons (74 vs. 106) and neurologists (20 vs. 37) is increasing by 42.5% and 112%, respectively. CONCLUSIONS: This survey suggests that there is a strong interest in endovascular surgical neuroradiology. The overall number of graduates is increasing, particularly in neurosurgery and neurology. Although the majority of current faculty is still comprised of neuroradiologists, the number of graduates in radiology will be decreasing during the next 5 years, reflecting a trend toward greater subspecialization within the fields of neurosurgery and neurology.

Trends in workforce diversity in vascular surgery programs in the United States.

BACKGROUND: U.S. black and Hispanic populations are growing at a steady pace. In contrast, the medical profession lacks the same minority growth and representation. Women are also under-represented in many surgical disciplines. The purpose of this study was to assess trends in the proportion of women, blacks, and Hispanics admitted to vascular surgery (VS) and related specialties, and to compare them with each other and with a surgical specialty, orthopedic surgery (OS), with a formal diversity initiative. METHODS: Data on the fellowship pool of VS, interventional radiology (IR), and interventional cardiology (IC), as well as the resident pools of general surgery (GS) and orthopedic surgery (OS), were obtained from U.S. graduate medical education reports for 1999 through 2005. Cochrane-Armitage trend tests were used to assess trends in the proportion of females, blacks, and Hispanics in relation to the total physician workforce for each subspecialty. RESULTS: No significant trends in the proportion of females, blacks, or Hispanics accepted into VS and IC fellowship programs occurred during the study period. In contrast, IR, GS, and OS programs revealed significant trends for increasing proportions of at least one of the underrepresented study groups. In particular, OS, which has implemented a diversity awareness program, showed a positive trend in female and Hispanic trainees (P < .04 and P < .02, respectively). Blacks showed a significant increasing trend only in IR (P = .05). Conversely, a positive trend toward continued growth in the Hispanic group was seen in GS (P < .001), IR, and OS (P = .04 and P = .02, respectively). CONCLUSIONS: The racial/ethnic and gender composition of the physician trainee pool in vascular specialties, particularly VS, has not matched the increasing growth of underrepresented groups in the US population of patients with vascular disease. Formal programs to recruit qualified women and minorities appear successful in increasing workforce diversity.
