Online Ratings for Vascular Interventional Proceduralists Vary by Physician Specialty.

BACKGROUND: Multiple specialties offer vascular interventional care, creating potential competition for referrals and procedures. At the same time, patient/consumer ratings have become more impactful for physicians who perform vascular procedures. We hypothesized that there are differences in online ratings based on specialty. METHODS: We used official program lists from the Association for Graduate Medical Education to identify institutions with training programs in integrated vascular surgery (VS), integrated interventional radiology (IR), and interventional cardiology (IC). Faculty providers were identified in each specialty at these institutions. A standardized search was performed to collect online ratings from Vitals.com, Healthgrades.com, and Google.com as well as from online demographics. Between specialty differences were analyzed using chi-squared and analysis of variance tests as appropriate. Multivariable linear regression was used to identify factors associated with review volume and star rating. RESULTS: A total of 1,330 providers (n = 454 VS, n = 451 IR, n = 425 IC) were identified across 47 institutions in 27 states. VS (55.5%-69.4%) and IC (63.8%-71.1%) providers were significantly more likely to have reviews than IR (28.6%-48.8%) providers across all online platforms (P < 0.001 for all websites). Across all platforms, IC providers were rated significantly higher than VS and IR providers. Multivariable regression showed that provider specialty and additional time in practice were associated with higher review volume. In addition to specialty, review volume was associated with star rating as those physicians with more reviews tended to have a higher rating. CONCLUSIONS: On average, vascular surgeons have more reviews and are more highly rated than interventional radiologists but tend to have fewer reviews and lower ratings than interventional cardiologists. VS providers may benefit from encouraging patients to file online reviews, especially in competitive markets.

Changes in IR from 2007 to 2017 in China.

In this article, the updated status of interventional radiology (IR) in China is reported and compared vs that a decade ago based on a poll carried out in 2017 in Jiangsu Province, where the economy and overall health level are among the best of the 31 provinces in China. All 98 polled centers responded, and 56 IR departments (57%) had become independent departments separate from the radiology department; 74 (76%) had inpatient wards. In 2017, there were 538 interventional radiologists performing IR procedures in Jiangsu Province, with a total of 69,277 procedures performed, with interventional oncologic procedures accounting for the largest proportion (58%).

Financial Effect of Unbundling Moderate Sedation from Procedural Codes in Radiology.

PURPOSE: To assess and quantify the financial effect of unbundling newly unbundled moderate sedation codes across major payors at an academic radiology practice. MATERIALS AND METHODS: Billing and reimbursement data for 23 months of unbundled moderate sedation codes were analyzed for reimbursement rates and trends. This included 10,481 and 28,189 units billed and $443,257 and $226,444 total receipts for codes 99152 (initial 15 minutes of moderate sedation) and 99153 (each subsequent 15 minute increment of moderate sedation), respectively. Five index procedures-(i) central venous port placement, (ii) endovascular tumor embolization, (iii) tunneled central venous catheter placement, (iv) percutaneous gastrostomy placement, and (v) percutaneous nephrostomy placement-were identified, and moderate sedation reimbursements for Medicare and the dominant private payor were calculated and compared to pre-bundled reimbursements. Revenue variation models across different patient insurance mixes were then created using averages from 4 common practice settings among radiologists (independent practices, all hospitals, safety-net hospitals, and non-safety-net hospitals). RESULTS: Departmental reimbursement for unbundled moderate sedation in FY2018 and FY2019 totaled $669,701.34, with high per-unit variability across payors, especially for code 99153. Across the 5 index procedures, moderate sedation reimbursement decreased 1.3% after unbundling and accounted for 3.9% of procedural revenue from Medicare and increased 11.9% and accounted for 5.5% of procedural revenue from the dominant private payor. Between different patient insurance mix models, estimated reimbursement from moderate sedation varied by as much as 29.9%. CONCLUSIONS: Departmental reimbursement from billing the new unbundled moderate sedation codes was sizable and heterogeneous, highlighting the need for consistent and accurate reporting of moderate sedation. Total collections vary by case mix, patient insurance mix, and negotiated reimbursement rates.

Institutional Variability in Patient Radiation Doses ≥5 Gy During Percutaneous Coronary Intervention.

OBJECTIVES: The aim of this study was to evaluate institutional variability in high radiation doses during percutaneous coronary intervention (PCI). BACKGROUND: It is unknown whether radiation safety practices are optimally applied across institutions performing PCI. METHODS: Using data from a large statewide registry, PCI discharges between July 1, 2016, and March 31, 2018, with a procedural air kerma (AK) recorded were analyzed. PCI procedures were grouped by the performing hospital, and institutional frequency of procedural AK ≥5 Gy was calculated. Fitted hierarchical Bayesian modeling was performed to identify variables independently associated with an AK ≥5 Gy. The performing hospital was included as a random effect in the hierarchical model. RESULTS: Among 36,201 PCI procedures at 28 hospitals, procedural AK was ≥5 Gy in 1,477 cases (4.1%), ≥10 Gy in 185 (0.5%), and ≥15 Gy in 105 (0.3%). The institutional frequency of procedural AK ≥5 Gy ranged from 0.0% to 10.9%. Bayesian modeling identified body mass index, dyslipidemia, diabetes, prior coronary bypass surgery, use of mechanical circulatory support, and the performing hospital as independent predictors of an AK ≥5 Gy. The median odds ratio for the performing hospital, representing an estimate of the contribution of interhospital variability in determining the odds of having a procedural AK ≥5 Gy, was 3.08 (95% confidence interval: 3.01 to 3.16). CONCLUSIONS: Wide variability exists in the institutional frequency of procedural AK ≥5 Gy during PCI. After accounting for patient characteristics and procedural variables, the performing hospital appears to be a major factor in determining patient radiation dose in contemporary PCI.

European trends in radiology: investigating factors affecting the number of examinations and the effective dose.

The advances in technology have led to a growing trend in population exposure to radiation emerging from the invention of high-dose procedures. It is, for example, estimated that annually 1.2% of cancers are induced by radiological scans in Norway. This study aims to investigate and discuss the frequency and dose trends of radiological examinations in Europe. European Commission (EC) launched projects to gain information for medical exposures in 2004 and 2011. In this study, the European Commission Radiation Protection (RP) reports No. 154 and 180 have been reviewed. The RP 154 countries' data were extracted from both reports, and the average variation trend of the number of examinations and effective doses were studied. According to the results, plain radiography and fluoroscopy witnessed a reduction in the frequency and effective dose per examination. Nevertheless, European collective dose encountered an average increase of 23%, which resulted from a growing tendency for implementation of high-dose procedures such as CT scans and interventional examinations. It is worth noting that most of the CT procedures have undergone an increase in effective dose per examination. Although demand and dose per examination in some radiological procedures (such as intravenous urography (IVU) have been reduced, population collective dose is still rising due to the increasing demand for CT scan procedures. Even though the individual risks are not considerable, it can, in a large scale, threaten the health of the people at the present time. Due to this fact, better justification should be addressed so as to reduce population exposure.

Endoscopy as an Adjunct to Image-Guided Interventions: A New Frontier in Interventional Radiology.

Endoscopy is an underutilized technique in the practice of interventional radiology. The objectives of this article are to discuss potential uses of interventional radiology-operated endoscopy and to outline basic endoscopy setup and equipment uses. Endoscopy represents a new frontier to the fluoroscopically-guided procedures in biliary, gastrointestinal, and genitourinary disease that interventional radiologists commonly perform. It shows promise to improve interventional radiology procedure success rates and reduce procedure-associated risk for patients. Endoscopy has been traditionally performed by gastroenterologists and urologists and is relatively new in the practice of interventional radiology. The hand-eye coordination and manual dexterity required to perform standard image-guided procedures places interventional radiologists in a unique position to introduce endoscopy into standard practice. A focused and collaborative effort is needed by interventional radiologists to learn the techniques required to successfully integrate endoscopy into practice.

Locoregional treatments for hepatocellular carcinoma: Current evidence and future directions.

Liver cancers are the second most frequent cause of global cancer-related mortality of which 90% are attributable to hepatocellular carcinoma (HCC). Despite the advent of screening programmes for patients with known risk factors, a substantial number of patients are ineligible for curative surgery at presentation with limited outcomes achievable with systemic chemotherapy/external radiotherapy. This has led to the advent of numerous minimally invasive options including but not limited to trans-arterial chemoembolization, radiofrequency/microwave ablation and more recently selective internal radiation therapy many of which are often the first-line treatment for select stages of HCC or serve as a conduit to liver transplant. The authors aim to provide a comprehensive overview of these various image guided minimally invasive therapies with a brief focus on the technical aspects accompanied by a critical analysis of the literature to assess the most up-to-date evidence from comparative systematic reviews and meta-analyses finishing with an assessment of novel combination regimens and future directions of travel.

[Future of interventional radiology]. / Avenir de la radiologie interventionnelle.

Imaging-guided interventions or interventional radiology (IR) are intended to improve the efficiency and accuracy of the medical procedure regardless of the organ, as well as the safety and comfort of the patient. Currently IR concerns all medico-surgical specialties with a number of acts constantly increasing, and is today a major field of innovation that responds to a strong societal demand to move towards more and more effective treatments, but also less and less invasive. The ambulatory shift in IR is a major prospect of saving and improving the quality of care. In the field of innovations, technical developments are major for both guidance methods and interventional radiology equipment. These developments affect all organ pathologies, but it is certainly in the field of oncology that progress is fastest, with personalized medicine with new drugs targeted to optimize tolerance to treatment and maximize effects. The aim of this article is to make this specialty better known, its organization both in terms of training and the permanence of care.

Thoracic Duct Embolization: Analysis of Practice Patterns.

BACKGROUND: Thoracic duct embolization (TDE) has become the standard treatment for atraumatic and traumatic chylothoraces. Numerous approaches to embolization including intranodal lymphangiography, transabdominal, and retrograde catheterization of the thoracic duct have become the preferred methods for the treatment of chyle leaks. The purpose of this study was to determine training, treatment techniques, outcomes, and practice patterns of practitioners performing TDE. METHODS: From September to October of 2017, a 34-question survey focusing on training, treatment techniques, outcomes, and practice patterns of TDE was distributed through the Open Forum of the Society of Interventional Radiology Connect website. Fifty-four practitioners completed the entire survey. Percentages were calculated for answers to the questions. Chi-squared analysis was performed, comparing data from academic center respondents, private practice settings, and hybrid practice settings. P values < 0.5 were considered statistically significant. RESULTS: All responses were from interventional radiologists. Forty-seven practitioners (87.0%) performed TDE in the United States, and 1 performed (1.9%) abroad; 6 practitioners (11.1%) did not perform TDE. Of all, 88.9% (n = 48) performed TDE in academic (n = 24; 50%), private (n = 17; 35.4%), or hybrid (n = 6; 12.5%) practice settings. For diagnostic lymphangiography, 100% (n = 48) performed intranodal pelvic lymphangiography. A 25-gauge needle was used by 77.1% (n = 37) to access pelvic lymph nodes, and most (83.3%; n = 40) reported using manual hand injection to administer ethiodized oil. Nine of 24 (37.5%) respondents in academic practice and 15 of 23 (65.2%) in private practice were successful in cannulating the thoracic duct >80% of the time. Most referrals were from thoracic surgery (n = 47; 97.9%). CONCLUSIONS: TDE is performed by practitioners in both academic and private practice settings. Treatment techniques were similar for a majority of operators. Technical success rates were higher in private practice. Most referrals were from thoracic surgery.

The future of anesthesia for interventional radiology.

PURPOSE OF REVIEW: To review novel procedures in interventional radiology and describe anesthetic implications. RECENT FINDINGS: Noninvasive treatment options for patients who are nonsurgical candidates are on the rise. The complication rate for patients receiving anesthesia in the interventional radiology suite is higher than other nonoperating room anesthetizing locations. The investigative use of catheter-directed thrombolysis for acute submassive pulmonary embolism will likely lead to an increased demand for anesthesia assistance. Treatment of prostate cancer with high-intensity focused ultrasound with MRI guidance is an alternative to surgical treatment and has unique anesthetic implications. With advances in technology, interventional radiologists have expanded their treatment armamentarium for benign and malignant bony lesions and thus the need for anesthesia assistance. SUMMARY: As the complexity of procedures and patients increases, the demand for anesthesia support in interventional radiology rises. As novel techniques are being developed, anesthesiologists must be mindful of the increased complication rate in interventional radiology and work in a multidisciplinary approach to improve patient safety.

Interventional nephrology: current status and clinical impact in Japan.

BACKGROUND: Current status and clinical significance of interventional nephrology has not been reported from Japan. METHODS: Questionnaires were mailed twice to the directors of all 534 Japanese certificated nephrology training institutions in 2014. The main questions were current performance, categorized annual procedure volume and managers of peritoneal dialysis (PD) access, vascular access (VA) surgery, endovascular intervention, and kidney biopsy. Frequencies of nephrologist involvement between high volume center and low volume center and association between the level of nephrologists' involvement to each procedure and annual procedure volume were examined. RESULTS: 332 (62.2%) institutions answered performance of all procedures and 328 (61.4%) institutions answered all procedure volume. Kidney biopsy, VA surgery, endovascular intervention and PD access surgery were performed by any doctors in 94.2, 96.3, 88.4, and 76.2% and each involvement of nephrologist was 93.9, 54.1, 53.1 and 47.6%, respectively. Cochran-Armitage analyses demonstrated significant increases in all 4 procedure volume with greater management by nephrologists (p < 0.01). Nephrologists involvement to VA surgery associated with procedure volume increase in not only VA surgery, but also PD catheter insertion (p < 0.01) and kidney biopsy (p < 0.05). And nephrologists involvement to PD catheter insertion also associated with surgical volume increase in both VA surgery (p < 0.01) and endovascular intervention (p < 0.05). CONCLUSIONS: Main manager of all 4 procedures was nephrologist in Japan. Each procedure volume increased as nephrologists become more involved. Acquisition of one specific procedure by nephrologist associated with increase not only in this specific procedure volume, but also the other procedure volume.

From interventionist imaging to intraoperative guidance: New perspectives by combining advanced tools and navigation with radio-guided surgery. / De la imagen intervencionista a la guía intraoperatoria: nuevas perspectivas combinando herramientas avanzadas y navegación con la cirugía radioguiada.

The integration of medical imaging technologies into diagnostic and therapeutic approaches can provide a preoperative insight into both anatomical (e.g. using computed tomography, magnetic resonance imaging, or ultrasound), as well as functional aspects (e.g. using single photon emission computed tomography, positron emission tomography, lymphoscintigraphy, or optical imaging). Moreover, some imaging modalities are also used in an interventional setting (e.g. computed tomography, ultrasound, gamma or optical imaging) where they provide the surgeon with real-time information during the procedure. Various tools and approaches for image-guided navigation in cancer surgery are becoming feasible today. With the development of new tracers and portable imaging devices, these advances will reinforce the role of interventional molecular imaging.

Strategies in Interventional Radiology: Formation of an Interdisciplinary Center of Vascular Anomalies - Chances and Challenges for Effective and Efficient Patient Management.

Background Radiology is an interdisciplinary field dedicated to the diagnosis and treatment of numerous diseases and is involved in the development of multimodal treatment concepts. Method Interdisciplinary case management, a broad spectrum of diagnostic imaging facilities and dedicated endovascular radiological treatment options are valuable tools that allow radiology to set up an interdisciplinary center for vascular anomalies. Results Image-based diagnosis combined with endovascular treatment options is an essential tool for the treatment of patients with highly complex vascular diseases. These vascular anomalies can affect numerous parts of the body so that a multidisciplinary treatment approach is required for optimal patient care. Conclusion This paper discusses the possibilities and challenges regarding effective and efficient patient management in connection with the formation of an interdisciplinary center for vascular anomalies with strengthening of the clinical role of radiologists. Key points · Vascular anomalies, which include vascular tumors and malformations, are complex to diagnose and treat.. · There are far more patients with vascular anomalies requiring therapy than interdisciplinary centers for vascular anomalies - there is currently a shortage of dedicated interdisciplinary centers for vascular anomalies in Germany that can provide dedicated care for affected patients.. · Radiology includes a broad spectrum of diagnostic and minimally invasive therapeutic tools which allow the formation of an interdisciplinary center for vascular anomalies for effective, efficient and comprehensive patient management..

IR and the Sunshine Act: Two-Year Analysis of the Open Payments Database and Comparison with Related Specialties.

PURPOSE: To characterize medical industry-based payments made to US-based interventional radiology (IR) physicians, identify trends in compensation, and compare their payment profile with those of other related specialties, including vascular surgery (VS) and interventional cardiology (IC). Payments made to orthopedic surgery (OS) physicians are reported as a historical control. MATERIALS AND METHODS: For each group, the total payment number, amount, and mean and median numbers and amounts were calculated. The data were then reanalyzed after correcting for statistical outliers. For IR, VS, and IC, leading industry sponsors, payment amount, and differences in payments from 2013 to 2014 were highlighted. Payments to IR were grouped by category and geographic location. The Kruskal-Wallis test was used for statistical analysis. RESULTS: A total of $26,857,622 went to 1,831 IR physicians, representing 70.9% of active IR physicians, and the corrected mean payment was $597 ± 832.2 (standard deviation). The respective values were $18,861,041, 3,383, 80.6%, and $851.59 for VS; $32,008,213, 7,939, 78.6%, and $417.16 for IC; and $357,528,020, 21,829, 77.8%, and $598.48 for OS. OS had the largest number of payments (295,465 vs 24,246 for IR, 84,635 for VS, and 160,443 for IC) and greatest total payment amount. VS had a significantly higher corrected median payment amount ($463; P < .0001) than IR ($214) and IC ($99). Covidien and Sirtex Medical were the leading industry sponsors to IR, and 64.6% of IR payments were compensation for services other than consulting. There was no significant difference in median payment received per geographic region (P = .32). CONCLUSIONS: OS received the largest number and total payment amount, and VS received a significantly greater corrected median payment amount, versus IR and IC. As the Open Payments program continues to be implemented, it remains to be seen how this information will affect relationships among physicians, patients, and industry.

New trends in interventional pulmonology.

PURPOSE OF REVIEW: As the field of interventional pulmonology continues to expand and develop at a rapid pace, anesthesiologists are increasingly called upon to provide well tolerated anesthetic care during these procedures. These patients may not be candidates for surgical treatment and often have multiple comorbidities. It is important for anesthesiologists to familiarize themselves with these procedures and their associated risks and complications. RECENT FINDINGS: The scope of the interventional pulmonologist's practice is varied and includes both diagnostic and therapeutic procedures. Bronchial thermoplasty is now offered as endoscopic treatment of severe asthma. Endobronchial lung volume reduction procedures are currently undergoing clinical trials and may become more commonplace. Interventional pulmonologists are performing medical thoracoscopy for the treatment and diagnosis of pleural disorders. Interventional radiologists are performing complex pulmonary procedures, often requiring anesthesia. SUMMARY: The review summarizes the procedures now commonly performed by interventional pulmonologists and interventional radiologists. It discusses the anesthetic considerations for and common complications of these procedures to prepare anesthesiologists to safely care for these patients. Investigational techniques are also described.
