ACR Appropriateness Criteria® Lower Extremity Chronic Venous Disease.

Lower extremity venous insufficiency is a chronic medical condition resulting from primary valvular incompetence or, less commonly, prior deep venous thrombosis or extrinsic venous obstruction. Lower extremity chronic venous disease has a high prevalence with a related socioeconomic burden. In the United States, over 11 million males and 22 million females 40 to 80 years of age have varicose veins, with over 2 million adults having advanced chronic venous disease. The high cost to the health care system is related to the recurrent nature of venous ulcerative disease, with total treatment costs estimated >$2.5 billion per year in the United States, with at least 20,556 individuals with newly diagnosed venous ulcers yearly. Various diagnostic and treatment strategies are in place for lower extremity chronic venous disease and are discussed in this document. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

ACR Appropriateness Criteria® Central Venous Access Device and Site Selection.

The use of central venous access devices is ubiquitous in both inpatient and outpatient settings, whether for critical care, oncology, hemodialysis, parenteral nutrition, or diagnostic purposes. Radiology has a well-established role in the placement of these devices due to demonstrated benefits of radiologic placement in multiple clinical settings. A wide variety of devices are available for central venous access and optimal device selection is a common clinical challenge. Central venous access devices may be nontunneled, tunneled, or implantable. They may be centrally or peripherally inserted by way of veins in the neck, extremities, or elsewhere. Each device and access site presents specific risks that should be considered in each clinical scenario to minimize the risk of harm. The risk of infection and mechanical injury should be minimized in all patients. In hemodialysis patients, preservation of future access is an additional important consideration. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Superficial thrombophlebitis in ipsilateral breast after COVID-19 vaccination.

On December 2020, the US Food and Drug Administration issued the first emergency use authorization for a vaccine for the prevention of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We report development of superficial thrombophlebitis in the ipsilateral breast of a 43-year-old female 7 days after receiving the first dose of the Pfizer-BioNTech COVID-19 vaccine. Given that this is the first case of superficial thrombophlebitis in the breast shortly after mRNA vaccination for COVID-19 reported to our knowledge, we suggest that this may be a rare vaccine-related event.

Imaging Utilization Patterns and Injury Characteristics Associated with Electric Standing Scooters in a Major Urban Area.

BACKGROUND: The recent proliferation of electric standing scooters in major urban areas of the United States has been accompanied by injuries of varying severity and nature, representing a growing public health concern. OBJECTIVE: Our aim was to characterize imaging utilization patterns for injuries associated with electric scooter (e-scooter) use, including their initial emergency department (ED) management. METHODS: We conducted a retrospective review of the electronic medical record for all patients presenting to affiliated EDs for e-scooter-related injuries between July 2018 and April 2020. Demographics, date and time of presentation, imaging study type, resultant injury, and procedural details were recorded. RESULTS: Ninety-seven patients were included; mean age was 27.6 years. Of these, 55 patients (57%) had injuries identified on imaging and 40% of all imaging studies were positive. Most identified injuries (61%) were musculoskeletal, with a small number of neurological (2%) and genitourinary (1%) injuries. The highest prevalence of presentations occurred in August; most patients (72%) presented between 3 pm and 1 am and granular peaks were between 12 am and 1 am and 5 pm and 6 pm. CONCLUSIONS: Patients presenting with e-scooter injuries have a high likelihood of injury to the radial head, nasal bone, and malleoli. Emergency physicians should be especially vigilant for injuries in these areas at presentation. Visceral injuries are uncommon but may be severe enough to warrant surgery.

Public Health Foundations for Radiology Resident Education: Healthcare Disparities in Radiology.

Increasing recognition within the medical literature and by the Accreditation Council for Graduate Medical Education has been attributed to the need for enhanced resident education on concepts related to public health and health equity. Despite increasing documentation of pervasive inequalities within the scope of radiology, dedicated curricula designed to improve cultural competency and understanding of healthcare disparities among radiology trainees remains sparse. With relatively fewer patient interactions, radiology trainees are particularly susceptible to insufficient contextual awareness of how socioeconomic factors influence patient health and behaviors, physician recommendations, and ultimately clinical outcomes. The purpose of this article is to provide a high-yield background of foundational health equity and disparity concepts for radiology trainees, from which additional educational curricula may be derived. Specifically, this article will discuss the fundamental socioeconomic factors known to contribute to discrepant access and use of imaging services, followed by areas in radiology with well-documented disparities of which trainees should be aware. Lastly, previous and current strategies for addressing disparities in radiology will be discussed with the ultimate goal of stimulating trainee participation and the development of novel approaches.

ACR Appropriateness Criteria® Radiologic Management of Lower Gastrointestinal Tract Bleeding: 2021 Update.

Diverticulosis remains the commonest cause for acute lower gastrointestinal tract bleeding (GIB). Conservative management is initially sufficient for most patients, followed by elective diagnostic tests. However, if acute lower GIB persists, it can be investigated with colonoscopy, CT angiography (CTA), or red blood cell (RBC) scan. Colonoscopy can identify the site and cause of bleeding and provide effective treatment. CTA is a noninvasive diagnostic tool that is better tolerated by patients, can identify actively bleeding site or a potential bleeding lesion in vast majority of patients. RBC scan can identify intermittent bleeding, and with single-photon emission computed tomography, can more accurately localize it to a small segment of bowel. If patients are hemodynamically unstable, CTA and transcatheter arteriography/embolization can be performed. Colonoscopy can also be considered in these patients if rapid bowel preparation is feasible. Transcatheter arteriography has a low rate of major complications; however, targeted transcatheter embolization is only feasible if extravasation is seen, which is more likely in hemodynamically unstable patients. If bleeding site has been previously localized but the intervention by colonoscopy and transcatheter embolization have failed to achieve hemostasis, surgery may be required. Among patients with obscure (nonlocalized) recurrent bleeding, capsule endoscopy and CT enterography can be considered to identify culprit mucosal lesion(s). The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Endovascular Thrombectomy of COVID-19-Related Large Vessel Occlusion: A Systematic Review and Summary of the Literature.

PURPOSE: Despite an overall reduction in the number of stroke cases presenting to hospitals during the COVID-19 pandemic, a remarkably high incidence of acute cerebrovascular disease associated with the infection has been reported. In this systematic review, we assess the neurological outcomes and complications of endovascular thrombectomy (EVT) for large vessel occlusions (LVO) in COVID-19 patients. METHODS: A literature search was performed in PubMed from December 1, 2019 through September 1st, 2020 using different combinations of suitable keywords. Ten studies reporting EVT outcomes and complications were identified. Two studies that included non-LVO pathologies and COVID-19 negative patients with the outcomes analysis were excluded. Patient demographics, comorbidities, anatomic thrombus location, neurological and angiographic outcomes were assessed. RESULTS: A total of 8 studies, in addition to our institutional case series, were ultimately included in this review. The mean age was 62.2 years, of which 67.6% were males. M1 segment involvement was the most commonly reported (53.8%) thrombus location. The mean NIHSS at presentation was 20.4 with no significant change at 24 h. Successful revascularization (TICI ≥ 2b) was achieved in 89%. Early proximal cerebral re-occlusion was reported in 6 patients (11%) and cerebral hemorrhage in 3 patients (4%). In hospital mortality was reported in 15 patients (28.8%). CONCLUSION: Despite angiographically successful EVT of LVOs in the majority of patients, this literature analysis demonstrates overall poor outcomes and high mortality in COVID-19 patients post EVT. An unusual incidence of early intracerebral proximal arterial re-occlusion was notable.

Gender Disparity in Radiology Society Committees and Leadership in North America and Comparison With Other Continents.

PURPOSE: To evaluate gender distribution in radiology professional society leadership positions. Our study intends to assess and compare the gender distribution among leadership roles and professional society committee memberships of the radiology societies and seek an understanding of potential associations between gender, academic research metrics, institutional academic rank, and leadership roles. METHODS: We identified radiology professional society committee members to assess relative gender composition in 28 radiology societies in North America, Europe, and Australia/New Zealand. The research metrics were obtained from the SCOPUS database and demographics and institutional affiliation through institutional websites' internet searches. Gender distribution by academic ranks and other discontinuous variables were analyzed using the Chi-Square test. Wallis tests. RESULTS: Of the 3011 members of society committees, 67.9% were male, and 32.1% female. Among all the society members, the data showed that the proportion of committee members holding leadership positions was comparable between males (25.7%) and females (22.5%). However, when we did a subgroup analysis and disaggregated the data by leadership positions, we noted that among those who held the leadership positions, the proportion of males was more significant (n = 526, 70.7%) compared to females (n = 218, 29.3%). Overall, males had higher median publications, citations, H-indices, and active years of research (P< 0.0001). At all university academic ranks, men outnumbered females (P = 0.0015, Chi-square 15.38), with the most considerable disparity at the rank of professor (71.9% male, 28.1% female, P = 0.0003). CONCLUSION: There was male predominance amongst committee members in radiology societies. Our study found no significant differences between those in leadership positions, suggesting that once a member of a committee, females are equally likely as males to attain leadership positions. Analysis of committee members' academic rank and committee leaders demonstrated underrepresentation of females at higher academic ranks, and males overall had higher research metrics than females.

Trends in Gender and Racial Profiles of US Academic Radiology Faculty.

OBJECTIVE: To evaluate gender and racial profiles of US academic radiology faculty. MATERIALS AND METHODS: This is a retrospective analysis of the American Association of Medical College database of radiology faculty members from 2006 to 2017 by academic rank, chair position, race or ethnicity, and gender. The data were described with annual proportions and average annual counts and fit to a Poisson regression model. Comparison data were taken from American Association of Medical College on matriculants at US medical schools and from ACGME on radiology residents. RESULTS: Women increased significantly in the ranks of professor by 4.5%, associate professor by 4.8%, and assistant professor by 4.8% (P < .05). Asian and multiple race non-Hispanic radiologists increased in the rank of professor by 5.9% and 3.1%, respectively (P < .05). Among department chairs, only women and Asian faculty increased by 6.4% and 7.5%, respectively (P < .05). The proportion of women chairs increased from 10.0% (19 of 191) in 2006 to 17.4% (39 of 224) in 2017. Black and Hispanic chairs collectively represented less than 10% of the total chairs every year. DISCUSSION: The significant percent annual increase in women faculty in academic ranks and chair positions suggests that the radiology faculty is becoming more diverse. However, the decreasing proportion of women with increasing academic ranks within each year of the study period suggests attrition or lack of promotion of women radiology faculty. The disparity in black and Hispanic faculty members and chairs suggests that emphasis should continue to be placed on tailored recruitment.

In 2018, a survey was sent to RADPEER participants to gauge the current state of the program and explore opportunities for continued improvement. A total of 26 questions were included, and more than 300 practices responded. In this report, the ACR RADPEER Committee authors summarize the survey results and discuss opportunities for future iterations of the RADPEER program.

Playing Well With Others: The Challenge of Academic and Community Radiology Practice Integration.

OBJECTIVE. In this article, we review models for clinical integration across the full spectrum of radiologic services in merged health systems that include both academic and community practice components. We also discuss the issues involved in the integration of disparate practice models and reward systems for both the community radiology group and the academic faculty practice group. CONCLUSION. Although we see advantages to the current trends in mergers and acquisitions within academic radiology, it remains to be seen whether academic and community practice radiology groups can truly work and play well together.

Curbing Inappropriate Usage of STAT Imaging at a Large Academic Medical Center.

PURPOSE: To evaluate a new system for processing and performing inpatient STAT diagnostic imaging with respect to utilization and time-based performance metrics. MATERIALS AND METHODS: This HIPAA-compliant study had institutional review board approval; informed consent was not required. The radiology information system of a large academic medical center was queried for all inpatient diagnostic imaging exams performed and interpreted from August 1, 2010, to October 31, 2012. Using customized software, data were evaluated based on order priority (non-STAT or STAT) and exam modality with respect to exam volume and time-based performance metrics (time-to-performance and preliminary interpretation time). Data were compared over 3 periods: August 1, 2010, to October 31, 2010 (preimplementation period); November 1, 2010, to October 31, 2011 (year 1 postimplementation); and November 1, 2011, to October 31, 2012 (year 2 postimplementation). RESULTS: In the first year after implementation of the new STAT policy, the percentage of inpatient exams ordered STAT significantly decreased from 22.1% to 5.4% (P < 0.001). This represented a proportional decrease of 26% (CT), 16% (MRI), 20% (US), and 24% (radiographs) relative to pre-STAT policy levels. The median time-to-performance and median preliminary interpretation time significantly decreased for all modalities after implementation of the policy (P < 0.05 for all modalities), decreasing by an average of 104 and 162 minutes, respectively. These changes persisted throughout year 2 postimplementation. CONCLUSION: A new institutional system for handling inpatient STAT diagnostic imaging results in a decreased number of STAT exams ordered and improved time-based performance metrics, thereby increasing workflow efficiency.

Patient Complaints in Image-Guided Interventions: Evaluation of Multifactorial Issues Using a Coding Taxonomy.

OBJECTIVE: The purpose of this article is to classify complaints from patients undergoing image-guided interventions using a coding taxonomy and to test whether single-coded complaints were resolved satisfactorily compared with multifactorial (multiple codes) complaints. MATERIALS AND METHODS: In this retrospective study, patients' complaint narratives between April 1999 and December 2012 were reviewed and categorized according to a three-level taxonomy into domains and codes. Resolutions were categorized as satisfactory or unsatisfactory to the patient and were classified as follows: clarification, apology, manager notification, change of provider, reimbursement, and quality review. Complaints were classified as single coded (only one code identified in the patients' description) and multifactorial (multiple codes identified). Statistical analysis was performed with the Fisher test, with the significance level set at 0.05. A run chart with the distribution of complaints by domains (relationships, management, and clinical) by year was performed. RESULTS: A total of 146 codes were extracted from 71 narratives (2.06 codes/complaint) and were classified into the following domains: clinical (52%; n = 76), management (24%; n = 35), and relationships (24%; n = 35). The most common codes included quality of care, safety, and communication breakdown issues. A run chart found a decline in absolute numbers of complaints over the years in the domains studied. The frequency of satisfactory resolution was 86% for multifactorial versus 81% for single-coded complaints with no statistically significant differences observed (p = 0.72). Over 50% of complaints were resolved by providing clarification to patients (n = 36). CONCLUSION: There were no statistically significant differences between multifactorial and single-coded complaints. Clinical codes and communication breakdown were the most common reasons for patient-reported complaint, with most complaints successfully resolved with clarification.

Checklist for a Radiology Information System Go-Live.

This article highlights the experience of a single center institution undergoing a change in radiology information system (RIS) software platforms, transitioning to an electronic medical record-RIS driven workflow. Ten planning and execution topics with recommendations are presented in checklist form from the radiology department perspective. The build process of creating a site specific RIS takes many months, beginning with the organization of a steering committee. On Go-Live, several checklist items are offered to help streamline the troubleshooting process and improve communication throughout the radiology department. The groundwork of the group effort in creating the infrastructure of the build process can continue to be useful beyond Go-Live, as RIS features are continually optimized.

Communicating Uncertainty in the Radiology Report.

OBJECTIVE: The purposes of this article are to explore the issue of diagnostic uncertainty in radiology and how the radiology report has often fallen short in this regard and to suggest approaches that can be helpful in addressing this challenge. CONCLUSION: The practice of medicine involves a great deal of uncertainty, which is an uncomfortable reality for most physicians. Radiologists are more often than not faced with considerable diagnostic uncertainty and in their written reports are challenged to effectively communicate that uncertainty to referring physicians and others.

Online Portals: Gateway to Patient-Centered Radiology.

OBJECTIVE: Online portals typically allow access to radiology reports, causing a shift in the communication. This article evaluates the studies available in the literature about patient portals and the use of patient portals in radiology. Patient and physician preferences and the impact on radiology reporting are presented. CONCLUSION: Patient portals provide an opportunity for radiologists to engage with their patients via a new method of communication. Radiologist collaboration with referring physicians is important in providing care in accordance with patient preferences.
