RESUMO
BACKGROUND: Comprehensive adverse event (AE) surveillance programs in interventional radiology (IR) are rare. Our aim was to develop and validate a retrospective electronic surveillance model to identify outpatient IR procedures that are likely to have an AE, to support patient safety and quality improvement. METHODS: We identified outpatient IR procedures performed in the period from October 2017 to September 2019 from the Veterans Health Administration (n = 135,283) and applied electronic triggers based on posyprocedure care to flag cases with a potential AE. From the trigger-flagged cases, we randomly sampled n = 1,500 for chart review to identify AEs. We also randomly sampled n = 600 from the unflagged cases. Chart-reviewed cases were merged with patient, procedure, and facility factors to estimate a mixed-effects logistic regression model designed to predict whether an AE occurred. Using model fit and criterion validity, we determined the best predicted probability threshold to identify cases with a likely AE. We reviewed a random sample of 200 cases above the threshold and 100 cases from below the threshold from October 2019 to March 2020 (n = 20,849) for model validation. RESULTS: In our development sample of mostly trigger-flagged cases, 444 of 2,096 cases (21.8%) had an AE. The optimal predicted probability threshold for a likely AE from our surveillance model was >50%, with positive predictive value of 68.9%, sensitivity of 38.3%, and specificity of 95.3%. In validation, chart-reviewed cases with AE probability >50% had a positive predictive value of 63% (n = 203). For the period from October 2017 to March 2020, the model identified approximately 70 IR cases per month that were likely to have an AE. CONCLUSIONS: This electronic trigger-based approach to AE surveillance could be used for patient-safety reporting and quality review.

The creation and maintenance of a dialysis access is vital for the reduction of morbidity, mortality, and cost of treatment for end stage renal disease patients. One's longevity on dialysis is directly dependent upon the quality of dialysis. This quality hinges on the integrity and reliability of the access to the patient's vascular system. All methods of dialysis access will eventually result in dialysis dysfunction and failure. Arteriovenous access dysfunction includes 3 distinct classes of events, namely thrombotic flow-related complications or dysfunction, nonthrombotic flow-related complications or dysfunction, and infectious complications. The restoration of any form of arteriovenous access dysfunction may be supported by diagnostic imaging, clinical consultation, percutaneous interventional procedures, surgical management, or a combination of these methods. This document provides a rigorous evaluation of how variants of each form of dysfunction may be appraised and approached systematically. 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 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 where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

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.

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.

Background Vascular access for ongoing hemodialysis often fails, frequently requiring repeated procedures to maintain vascular patency. While research has shown racial discrepancies in multiple aspects of renal failure treatment, there is poor understanding of how these factors might relate to vascular access maintenance procedures after arteriovenous graft (AVG) placement. Purpose To evaluate racial disparities associated with premature vascular access failure after percutaneous access maintenance procedures following AVG placement using a retrospective national cohort from the Veterans Health Administration (VHA). Materials and Methods All hemodialysis vascular maintenance procedures performed at VHA hospitals between October 2016 and March 2020 were identified. To ensure the sample represented patients who consistently used the VHA, patients without AVG placement within 5 years of their first maintenance procedure were excluded. Access failure was defined as a repeat access maintenance procedure or as hemodialysis catheter placement occurring 1-30 days after the index procedure. Multivariable logistic regression analyses were performed to calculate prevalence ratios (PRs) measuring the association between hemodialysis maintenance failure and African American race compared with all other races. Models controlled for vascular access history, patient socioeconomic status, and procedure and facility characteristics. Results In total, 1950 access maintenance procedures in 995 patients (mean age, 69 years ± 9 [SD], 1870 men) with an AVG created in one of 61 VHA facilities were identified. Most procedures involved African American patients (1169 of 1950, 60%) and patients residing in the South (1002 of 1950, 51%). Premature access failure occurred in 215 of 1950 (11%) procedures. When compared with all other races, African American race was associated with premature access site failure (PR, 1.4; 95% CI: 1.07, 1.43; P = .02). Among the 1057 procedures in 30 facilities with interventional radiology resident training programs, there was no evidence of racial disparity in the outcome (PR, 1.1; P = .63). Conclusion African American race was associated with higher risk-adjusted rates of premature arteriovenous graft failure after dialysis maintenance. © RSNA, 2023 Supplemental material is available for this article.

OBJECTIVES: Interventional radiology (IR) is the newest medical specialty. However, it lacks robust quality assurance metrics, including adverse event (AE) surveillance tools. Considering the high frequency of outpatient care provided by IR, automated electronic triggers offer a potential catalyst to support accurate retrospective AE detection. METHODS: We programmed previously validated AE triggers (admission, emergency visit, or death up to 14 days after procedure) for elective, outpatient IR procedures performed in Veterans Health Administration surgical facilities between fiscal years 2017 and 2019. We then developed a text-based algorithm to detect AEs that explicitly occurred in the periprocedure time frame: before, during, and shortly after the IR procedure. Guided by the literature and clinical expertise, we generated clinical note keywords and text strings to flag cases with high potential for periprocedure AEs. Flagged cases underwent targeted chart review to measure criterion validity (i.e., the positive predictive value), to confirm AE occurrence, and to characterize the event. RESULTS: Among 135,285 elective outpatient IR procedures, the periprocedure algorithm flagged 245 cases (0.18%); 138 of these had ≥1 AE, yielding a positive predictive value of 56% (95% confidence interval, 50%-62%). The previously developed triggers for admission, emergency visit, or death in 14 days flagged 119 of the 138 procedures with AEs (73%). Among the 43 AEs detected exclusively by the periprocedure trigger were allergic reactions, adverse drug events, ischemic events, bleeding events requiring blood transfusions, and cardiac arrest requiring cardiopulmonary resuscitation. CONCLUSIONS: The periprocedure trigger performed well on IR outpatient procedures and offers a complement to other electronic triggers developed for outpatient AE surveillance.

Achieving parity in representation within the field of Interventional Radiology (IR) across women and specific subsets of minority groups has been a challenge. The lack of a strongly diverse physician workforce in gender, race, and ethnicity suggests suboptimal recruitment after, during as well prior to IR training. There is a dearth of studies which effectively characterize the national demographic trends of the evolving IR workforce. This has prevented an accurate appraisal of continuing efforts to narrow the gaps in physician workforce diversity across the field of IR. To support these needs, this article illustrates historic trends while providing contemporary data that canvasses the status of diversity within the current IR physician and IR trainee workforce. It highlights the representation of those individuals historically underrepresented in medicine as well as women. It also highlights current obstacles to achieving equity, diversity, and inclusion within the field of IR as well as existing efforts that have been employed to mitigate this gap.

Mesenteric ischemia is a serious medical condition characterized by insufficient vascular supply to the small bowel. In the acute setting, endovascular interventions, including embolectomy, transcatheter thrombolysis, and angioplasty with or without stent placement, are recommended as initial therapeutic options. For nonocclusive mesenteric ischemia, transarterial infusion of vasodilators, such as papaverine or prostaglandin E1, is the recommended initial treatment. In the chronic setting, endovascular means of revascularization, including angioplasty and stent placement, are generally recommend, with surgical options, such as bypass or endarterectomy, considered alternative options. Although the diagnosis of median arcuate ligament syndrome remains controversial, diagnostic angiography can be helpful in rendering a diagnosis, with the preferred treatment option being a surgical release. Systemic anticoagulation is recommended as initial therapy for venous mesenteric ischemia with acceptable rates of recanalization. If anticoagulation fails, transcatheter thrombolytic infusion can be considered with possible adjunctive placement of a transjugular intrahepatic portosystemic shunt to augment antegrade flow. 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.

Trauma remains a leading cause of death for all age groups, and nearly two-thirds of these individuals suffer thoracic trauma. Due to the various types of injuries, including vascular and nonvascular, interventional radiology plays a major role in the acute and chronic management of the thoracic trauma patient. Interventional radiologists are critical members in the multidisciplinary team focusing on treatment of the patient with thoracic injury. Through case presentations, this article will review the role of interventional radiology in the management of trauma patients suffering thoracic injuries.
RESUMO
OBJECTIVE: To examine the prevalence of burnout among radiology trainees in the United States, and to study the relationships between burnout and professional fulfillment (PF), intent-to-leave (ITL), sleep-related impairment and self-compassion by gender. METHODS: This cross-sectional study was conducted via an anonymous electronic survey sent to 11 large academic medical centers (Physician Wellness Academic Consortium) between January 2017 and September 2018. The survey included the Professional Fulfillment Index (PFI) and an abbreviated form of the PROMIS Sleep-related impairment (SRI) scale. Two-sample t-tests and chi-square exact tests were used for analysis (p < 0.05). RESULTS: Two hundred forty-seven radiology residents responded to the survey. Out of these, 36.2% reported burnout, 37.4% endorsed PF, 64.8% reported sleep-related impairment, 7.6% expressed ITL. There were no significant differences between genders. Burnout was associated with reduced PF, increased sleep-impairment (p < 0.001 for both) and increased ITL (p = 0.02). Lower PF, peer support, perceived appreciation for and meaningfulness in work, alignment of organizational and personal values, self-compassion, and higher sleep impairment were associated with burnout (p < 0.001 for all). Burnout was associated with perceptions of less support from department leaders (p = 0.003), control over schedules (p = 0.001) and helpfulness of electronic health record systems (p = 0.01). ITL was associated with reduced PF, perceived work appreciation, and leadership support (p = 0.03, p = 0.04, and p = 0.007, respectively). DISCUSSION: Burnout is prevalent among radiology residents. Many demonstrate sleep-impairment and reduced professional fulfillment, with a lesser fraction desiring to leave their institution. Key factors to burnout included peer and organizational support, electronic health record systems helpfulness, and personal factors like self-compassion and work appreciation.

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.

OBJECTIVE: To examine the prevalence of burnout in faculty radiologists in the United States and to explore the relationship between burnout and professional fulfillment (PF), intention to leave (ITL), and sleep-related impairment by gender. METHODS: This cross-sectional study was conducted through a voluntary anonymous, electronic survey of radiologists at 11 academic medical institutions participating in the Physician Wellness Academic Consortium between January 2017 and September 2018. Faculty radiologists who completed the survey were included in the study. The survey contained the validated professional fulfillment index and National Institute of Health Patient Reported Outcomes Measurement Information System sleep-related impairment scale. Demographics of participants only included gender to protect anonymity. Sample t tests and χ2 exact tests were used for analysis with significance level set at P < .05. RESULTS: In all, 456 faculty radiologists (171 women) answered the survey. The overall prevalence of burnout was 37.4%, PF was 35.6%, ITL was 33.3%, and sleep-related impairment was 45.3%. Burnout was higher in female versus male respondents (44% versus 31%, P < .05), and PF and ITL were lower (30% versus 42%, P < .05, 26% versus 38%, P < .05, respectively). When faculty were stratified into burned out versus not burned out, PF was significantly lower in those with burnout (12% versus 52%, P < .05), and ITL and sleep-related impairment was higher (51% versus 24%, P < .05 and 75% versus 30%, P < .05, respectively). DISCUSSION: Higher burnout was associated with reports of greater ITL and sleep-related impairment and lower PF. Female radiologists experience more burnout but less ITL than their male counterparts.

This study investigated the clinical outcomes for patients with pelvic ultrasound findings suspicious for uterine arteriovenous malformations (AVMs) at a single institution. We reviewed the electronic medical record to identify women with pelvic ultrasound reports read as possible uterine AVM, and used medical records to determine clinical outcomes. Among the 39 women with ultrasounds suspicious for AVM, 14 had subsequent MRIs, 10 had additional ultrasounds, and 10 underwent pelvic angiography. Five of the 39 women were ultimately diagnosed with AVMs. Of the 34 women who did not have an AVM, 12 were diagnosed with retained products of conception. Women may be receiving overtreatment for possible uterine AVMs; careful clinical consideration is warranted as the most common clinical diagnosis for women with radiologic findings suspicious of uterine AVM is retained products of conception.Impact statementWhat is already known on the subject: An acquired uterine arteriovenous malformation (AVM) is an abnormal arterio-venous connection in the myometrium that may cause life-threatening haemorrhage. Over the past decade, it has been noted that the characteristic ultrasound findings of uterine AVM may represent other causes of uterine hypervascularity including retained products of conception.What the results of this study add: As there is no consensus on the management of highly vascular myometrial lesions suspicious for uterine AVMs, this study reports our institution's experience with pelvic ultrasound findings suspicious for uterine AVMs. We found that further diagnostic workup, including MRI and angiography were common, but that the most frequent final diagnosis was retained products of conception.What the implications are of these findings for future clinical practice: This study contributes to the growing body of work noting spectrum of conditions with similar vascular ultrasound findings, and suggests that at least in this sample, women may be receiving overtreatment for these presumed uterine AVMs. Close collaboration among gynaecologists and radiologists is needed to interpret the significance of these radiographic images and to determine the appropriate intervention, as women with radiologic findings suspicious of uterine AVM will frequently have retained products of conception.

Iliofemoral venous thrombosis carries a high risk for pulmonary embolism, recurrent deep vein thrombosis, and post-thrombotic syndrome complicating 30% to 71% of those affected. The clinical scenarios in which iliofemoral venous thrombosis is managed may be diverse, presenting a challenge to identify optimum therapy tailored to each situation. Goals for management include preventing morbidity from venous occlusive disease, and morbidity and mortality from pulmonary embolism. Anticoagulation remains the standard of care for iliofemoral venous thrombosis, although a role for more aggressive therapies with catheter-based interventions or surgery exists in select circumstances. Results from recent prospective trials have improved patient selection guidelines for more aggressive therapies, and have also demonstrated a lack of efficacy for certain conservative therapies. 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.

BACKGROUND: Little is known about the level of burnout among program administrators (PAs) in medical education and its impact on the trainee environment. OBJECTIVE: To investigate variations in burnout levels over a 1-year period among a national cohort of PAs and examine any associations between perceived support and isolation. DESIGN: A 1-year longitudinal study conducted to assess burnout levels among PAs across the USA. The Copenhagen Burnout Inventory (score range, 0-100) was used to measure burnout over one academic year (July 2017-June 2018). The generalized estimating equations model was used to measure changes in burnout levels from the start of the academic year. To explore the differences in burnout scores across question response levels, a one-way ANOVA test was utilized and reported as least squares means ± SD. PARTICIPANTS: Individuals who self-identified as PAs in a graduate medical education training program. Among the 1084 persons nationwide who expressed interest, 904 (83%) completed the baseline survey; 29 of the 42 (69%) local administrators completed the survey. "Clients" defined as interns, residents/fellows, and medical students. MAIN MEASURES: Change in burnout score using the validated tool. Hypothesis formulated prior to data collection. KEY RESULTS: Among the 931 participants, the 3rd quarter (March 2018) marked the lowest average personal burnout score (change from the start of academic year, - 3.67; p < 0.001, 95% CI - 5.77 to - 1.58) and work-related burnout score (change, - 3.03; p < 0.001, 95% CI - 5.01 to - 1.06). Client-related burnout was the lowest in September 2017 (change, - 1.46; p = 0.491; 95% CI - 3.54 to 0.62). June 2018: those who strongly agreed to feeling isolated in their current position had an increased personal (69.1 ± 18.4 SD), work-related (72.5 ± 20.8 SD), and client-related (42.3 ± 23.7 SD) burnout score. CONCLUSIONS: PA burnout levels fluctuate over the academic year and are shown to increase as feelings of isolation grow.

OBJECTIVE. The purpose of this study is to review the various techniques and clinical management paradigms using tissue plasminogen activator (tPA) to treat severe frostbite injuries, which are relevant to the interventional radiologist. MATERIALS AND METHODS. A literature search yielded 157 citations, which were manually screened for inclusion criteria of case reports, case series, cohort studies, and randomized prospective studies that reported the use of tPA to treat severe frostbite injuries, of which 16 qualified for review. Data extracted from the studies included authors, journal, year of publication, initial assessment and management of severe frostbite injuries, inclusion and exclusion criteria for tPA therapy, treatment and control group size, different imaging modalities used in evaluation of severe frostbite injuries, tPA treatment protocols, outcomes, and side effects or complications. RESULTS. The analyzed series included 209 patients with 1109 digits at risk of amputation who were treated with intraarterial (IA) or IV tPA (116 and 77 patients, respectively). A total of 926 digits at risk were treated with IA tPA and resulted in amputation of 222 digits, for a salvage rate of 76%. Twenty-four of 63 patients underwent amputation after IV tPA, resulting in a salvage rate of 62%. Both digital subtraction angiography and triple-phase bone scan were used for initial imaging evaluation. Additional concurrent treatment included therapeutic heparin, warfarin, nonsteroidal antiinflammatory drugs, pain management, and light dressings with topical antimicrobial agents. CONCLUSION. Severe frostbite injuries can lead to devastating outcomes with loss of limbs and digits, yet clinical management continues to consist primarily of tissue rewarming, prolonged watchful waiting, and often delayed amputation. Recent studies have shown promising results using both IA and IV tPA to reduce amputation after severe frostbite injuries. Through a meta-analysis of thrombolytic therapy in the management of severe frostbite, this article provides a useful guideline for interventional radiologists including a suggested protocol, inclusion and exclusion criteria, and potential complications.

BACKGROUND: Little is known about the level of burnout among program administrators (PAs) working in graduate medical education. OBJECTIVE: We created a national database with baseline burnout data for PAs from residency and fellowship programs, including intention to leave their current positions. METHODS: A cross-sectional study was conducted in July 2017 to assess levels of burnout in a national cohort of PAs, who were largely members of online specialty forums. The Copenhagen Burnout Inventory (CBI) was used to measure burnout. Univariate analysis produced descriptive statistics for CBI. We performed a 2-sample t test to measure differences in average burnout scores for those who had thoughts of resigning from their positions and those who had not. RESULTS: Of the approximately 10â205 national PAs, we sampled 1126 (11%). Of the 1126 individuals who received the study information, 931 (83%) completed the baseline survey. Total mean scores for all subscales were elevated (personal: 53.7, SD 21.4; work-related: 52.0, SD 22; and client-related: 30.6, SD 20.8; each scale ranged from 0, low, to 100, high). Burnout scores differed between those contemplating leaving their jobs and those who were not, across all subscales of CBI, including personal (64.2 versus 42.4, -24.18 to -19.44 confidence interval [CI]), work-related (63.5 versus 39.7, -26.12 to -21.35 CI), and client-related (36.6 versus 24.2, -14.95 to -9.84 CI; P < .0001 for all). CONCLUSIONS: In this national survey of PAs, burnout scores measured by the CBI were higher among those who had considered leaving their positions.
