Current Interventional Radiology-Related Benchmarked Clinical Quality Measures Are Less Likely to be "Capped" Than Diagnostic Radiology Clinical Quality Measures.

In the merit-based incentive payment system (MIPS), quality measures are considered topped out if national median performance rates are ≥95%. Quality measures worth 10 points can be capped at 7 points if topped out for ≥2 years. This report compares the availability of diagnostic radiology (DR)-related and interventional radiology (IR)-related measures worth 10 points. A total of 196 MIPS clinical quality measures were reviewed on the Center for Medicare and Medicaid Services MIPS website. There are significantly more IR-related measures worth 10 points than DR measures (2/9 DR measures vs 9/12 IR measures; P = .03), demonstrating that clinical IR services can help mixed IR/DR groups maximize their Center for Medicare and Medicaid Services payment adjustment.

Provision of Italian diagnostic reference levels for diagnostic and interventional radiology.

OBJECTIVES: The diagnostic reference level (DRL) is a useful tool for the optimisation of medical exposures. Thus, a Working Party coordinated by the Italian National Institute of Health and the National Workers Compensation Authority has been formed to provide Italian DRLs, for both diagnostic and interventional procedures, to be used as appropriate for the implementation of the 2013/59 European Directive into the national regulation. MATERIALS AND METHODS: The multidisciplinary Working Party was formed by professionals involved in diagnostic and interventional radiology medical exposures and started from a critical revision of both the literature and the results of previous Italian surveys. The procedures were divided into five sections for adult (projection radiography, mammography, diagnostic fluoroscopy, CT and interventional radiology) and two sections for paediatric patients (projection radiography and CT). The provided DRL values have been identified for "normal" adult patients and for age-classes of paediatric patients. RESULTS: Some of the DRL values provided by the Working Party are reported in this study as an example, divided by adult/paediatric patients, radiological technique and examination: specifically, DRLs for new radiological practices and new dose quantities as DRLs metric were introduced. The median value (rather than the mean) for each procedure, derived from a sample of patients, has to be compared with the corresponding DRL value, and dosimetric data related to a minimum number of patients should be collected for each examination. CONCLUSIONS: The approach to the definition and use of DRLs through guidelines of national Authorities in collaboration with scientific Associations should simplify the periodical updating and could be useful for keeping the optimisation of medical exposures faithful to the development of radiological practice.

Society of Interventional Radiology Clinical Practice Guideline for Inferior Vena Cava Filters in the Treatment of Patients with Venous Thromboembolic Disease: Developed in collaboration with the American College of Cardiology, American College of Chest Physicians, American College of Surgeons Committee on Trauma, American Heart Association, Society for Vascular Surgery, and Society for Vascular Medicine.

PURPOSE: To provide evidence-based recommendations on the use of inferior vena cava (IVC) filters in the treatment of patients with or at substantial risk of venous thromboembolic disease. MATERIALS AND METHODS: A multidisciplinary expert panel developed key questions to address in the guideline, and a systematic review of the literature was conducted. Evidence was graded based on a standard methodology, which was used to inform the development of recommendations. RESULTS: The systematic review identified a total of 34 studies that provided the evidence base for the guideline. The expert panel agreed on 18 recommendations. CONCLUSIONS: Although the evidence on the use of IVC filters in patients with or at risk of venous thromboembolic disease varies in strength and quality, the panel provides recommendations for the use of IVC filters in a variety of clinical scenarios. Additional research is needed to optimize care for this patient population.

Clinical Practice Characteristics of Radiologists Based on American Board of Radiology Interventional Radiology Certification Status.

OBJECTIVE. The objective of this study was to assess clinical practice characteristics of radiologists on the basis of American Board of Radiology (ABR) interventional radiology (IR) certification status. MATERIALS AND METHODS. Medicare-participating radiologists were linked with ABR diplomates using the ABR's public search engine. Radiologists with an interventional radiology/diagnostic radiology (IR/DR) certificate (offered since 2017) were deemed currently IR-certified (n = 2840), and those assigned a vascular and interventional radiology subspecialty certificate (now defunct by the ABR) were deemed previously IR-certified (n = 900). Physician characteristics were obtained from Centers for Medicare & Medicaid Services (CMS) data. RESULTS. Overall, the mean percentage work effort in IR was higher for radiologists currently IR-certified than it was for radiologists who were previously IR-certified (65.9% vs 30.6%). Although 41.2% of currently IR-certified diplomates had more than 90% IR work effort, 35.7% had 50% or less IR work effort. Radiologists with current IR certification versus those with previous IR certification were more likely to be in an academic practice (25.1% vs 8.4%), a larger practice (in a practice with ≥ 100 members, 41.2% vs 22.4%), and earlier career stages (≤ 20 years in practice, 46.5% vs 0.6%). Of the 10 services most commonly billed by currently versus previously IR-certified radiologists, two and zero, respectively, were invasive procedures. Of identified CMS-participating radiologists with more than 50% IR effort, 27.2% (727/2670) were neither previously nor currently IR-certified. CONCLUSION. Although radiologists maintaining IR certification have higher IR work effort than those whose IR certification has lapsed, they are heterogeneous with overall sizable noninvasive diagnostic imaging practices. Approximately one-quarter of radiologists with predominant IR practices have never obtained IR certification. Because current IR/DR maintenance of certification testing exclusively addresses IR practice, attention is warranted to ensure certification is relevant to all IR diplomates.

Standards for European training requirements in interventional neuroradiology : Guidelines by the Division of Neuroradiology/Section of Radiology European Union of Medical Specialists (UEMS), in cooperation with the Division of Interventional Radiology/UEMS, the European Society of Neuroradiology (ESNR), and the European Society of Minimally Invasive Neurological Therapy (ESMINT).

This document sets out standards for training in Interventional Neuroradiology (INR) in Europe. These standards have been developed by a working group of the European Society of Neuroradiology (ESNR) and the European Society of Minimally Invasive Neurological Therapy (ESMINT) on the initiative and under the umbrella of the Division of Neuroradiology/Section of Radiology of the European Union of Medical Specialists (UEMS).

Standard procedures in nonoperating room anesthesia.

PURPOSE OF REVIEW: This article provides an overview of standard procedures currently performed in nonoperating room anesthesia (NORA) and highlights anesthetic implications. RECENT FINDINGS: Novel noninvasive interventional procedures remain on the rise, accelerating demand for anesthesia support outside the conventional operating room. The field of interventional oncology has introduced a variety of effective minimally invasive therapies making interventional radiology gain a major role in the management of cancer. Technical innovation brings newer ablative and embolotherapy techniques into practice. Flexible bronchoscopy has replaced rigid bronchoscopy for many diagnostic and therapeutic indications. Endobronchial ultrasonography now allows sampling of mediastinal, paratracheal, or subcarinal lymph nodes rendering more invasive procedures such as mediastinoscopy unnecessary. Similarly, endoscopic ultrasonosgraphy currently plays a central position in the management of gastrointestinal disease. Sophisticated catheter techniques for ablating cardiac arrhythmias have become state of the art; Watchman procedure gaining position in the prevention of stroke resulting from atrial fibrillation. SUMMARY: NORA is a rapidly evolving field in anesthesia. Employing new technology to treat a wide variety of diseases brings new challenges to the anesthesiologist. Better understanding of emerging interventional techniques is key to safe practice and allows the anesthesia expert to be at the forefront of this swiftly expanding multidisciplinary arena.

Patient radiation dose in percutaneous biliary interventions: recommendations for DRLs on the basis of a multicentre study.

OBJECTIVE: Percutaneous biliary interventions (PBIs) can be associated with a high patient radiation dose, which can be reduced when national diagnostic reference levels (DRLs) are kept in mind. The aim of this multicentre study was to investigate patient radiation exposure in different percutaneous biliary interventions, in order to recommend national DRLs. METHODS: A questionnaire asking for the dose area product (DAP) and the fluoroscopy time (FT) in different PBIs with ultrasound- or fluoroscopy-guided bile duct punctures was sent to 200 advanced care hospitals. Recommended national DRLs are set at the 75th percentile of all DAPs. RESULTS: Twenty-three facilities (9 interventional radiology depts. and 14 gastroenterology depts.) returned the questionnaire (12%). Five hundred sixty-five PBIs with 19 different interventions were included in the analysis. DAPs (range 4-21,510 cGy·cm2) and FTs (range 0.07-180.33 min) varied substantially depending on the centre and type of PBI. The DAPs of initial PBIs were significantly (p < 0.0001) higher (median 2162 cGy·cm2) than those of follow-up PBIs (median 464 cGy·cm2). There was no significant difference between initial PBIs with ultrasound-guided bile duct puncture (2162 cGy·cm2) and initial PBIs with fluoroscopy-guided bile duct puncture (2132 cGy·cm2) (p = 0.85). FT varied substantially (0.07-180.33 min). CONCLUSIONS: DAPs and FTs in percutaneous biliary interventions showed substantial variations depending on the centre and the type of PBI. PBI with US-guided bile duct puncture did not reduce DAP, when compared to PBI with fluoroscopy-guided bile duct puncture. National DRLs of 4300 cGy·cm2 for initial PBIs and 1400 cGy·cm2 for follow-up PBIs are recommended. KEY POINTS: • DAPs and FTs in percutaneous biliary interventions showed substantial variations depending on the centre and the type of PBI. • PBI with US-guided bile duct puncture did not reduce DAP when compared to PBI with fluoroscopy-guided bile duct puncture. • DRLs of 4300 cGy·cm2for initial PBIs (establishing a transhepatic tract) and 1400 cGy·cm2for follow-up PBIs (transhepatic tract already established) are recommended.

Encouraging MSK imaging research towards clinical impact is a necessity: opinion paper of the European Society of Musculoskeletal Radiology (ESSR).

Radiology has not been spared in recent economic crises with a substantial reduction in the turnover of imaging equipment. These problems are exacerbated by increasing demand for healthcare across Europe. Therefore, using existing radiological services while rigorously following evidence-based guidelines might improve patient care. Thus, diagnostic pathways should be assessed not only for technical and diagnostic performance but also for their impact on medical and social outcome. In this paper, we report the advice of the Research Committee of ESSR on how we may guide musculoskeletal radiological research towards studies that have useful clinical impact. The ESSR Research Committee intends to encourage research with potential to influence treatment, patient outcome, and social impact. Key Points • Research in medical imaging has the potential to improve human health. • High-level studies have the potential to place radiology at the pinnacle of quality in evidence-based practice. • The ESSR Research Committee intends to encourage research with potential to influence treatment, patient outcome, and social impact.

Percutaneous management of bone metastases: state of the art, interventional strategies and joint position statement of the Italian College of MSK Radiology (ICoMSKR) and the Italian College of Interventional Radiology (ICIR).

Interventional radiology provides local management of bone metastases (BM) with a palliative intent in most cases, or with a curative intent in selected patients. Its role has rapidly expanded in the last decade, offering new treatment solutions often in combination with surgery, radiation therapy and medical treatments. The aim of the present paper is to increase awareness, acceptance and adoption of interventional radiology procedures for the treatment of BM; and to present the joint position of the Italian College of Musculoskeletal Radiology and the Italian College of Interventional Radiology.

Radiation safety education and compliance with safety procedures-The Korea Nurses' Health Study.

AIMS AND OBJECTIVES: To examine the current state of radiation safety education and its influence on nurses' compliance with safety procedures. BACKGROUND: Use of radiation in therapy and diagnosis has prolonged and improved millions of lives, but it presents potential hazards for healthcare professionals. DESIGN: A cross-sectional design. METHODS: Participants included 1,672 female nurses of childbearing age who had recently been exposed to radiation-emitting generators or radiation. Quantitative data were taken from the Korea Nurses' Health Study, the Korean version of the Nurses' Health Study conducted in the USA. Confounding variables included sociodemographic factors, duration of employment in a department where work involved radiation, hospital's geographical location, bed size and hospital safety climate. Statistical analyses included descriptive statistics, Spearman's correlation coefficients and multivariable ordinal logistic regression. RESULTS: Half (50.3%) of nurses received no safety training, whereas the other half received some safety training as follows: only once (14.4%), irregularly (10.2%) and regularly (25.1%). Of the six radioactive safety compliance questionnaires, 29.4%, 20.2%, 30.7% and 19.7% complied to none, one, two and more than three, respectively. After controlling for confounding variables, relative to that observed with no safety education, irregular education that occurred more than twice (OR = 1.597, CI = 1.177-2.164) and regular education (OR = 2.223, CI = 1.770-2.792) increased the likelihood that nurses would comply with safety procedures. CONCLUSIONS: Low levels of safety education and adherence raise critical concerns regarding nurses' well-being. As routine safety education increases safety adherence, healthcare managers and policymakers should emphasise regular safety education. RELEVANCE TO CLINICAL PRACTICE: Radiation safety education for nurses and their compliance with safety procedures have seldom been discussed in South Korea. However, as nurses' safety is directly related to the quality of patient care, additional safety education should be provided for hospital nurses to minimise their occupational exposure to harmful radioactive substances in clinical settings.

Proposal of a New Adverse Event Classification by the Society of Interventional Radiology Standards of Practice Committee.

PURPOSE: To develop a new adverse event (AE) classification for the interventional radiology (IR) procedures and evaluate its clinical, research, and educational value compared with the existing Society of Interventional Radiology (SIR) classification via an SIR member survey. MATERIALS AND METHODS: A new AE classification was developed by members of the Standards of Practice Committee of the SIR. Subsequently, a survey was created by a group of 18 members from the SIR Standards of Practice Committee and Service Lines. Twelve clinical AE case scenarios were generated that encompassed a broad spectrum of IR procedures and potential AEs. Survey questions were designed to evaluate the following domains: educational and research values, accountability for intraprocedural challenges, consistency of AE reporting, unambiguity, and potential for incorporation into existing quality-assurance framework. For each AE scenario, the survey participants were instructed to answer questions about the proposed and existing SIR classifications. SIR members were invited via online survey links, and 68 members participated among 140 surveyed. Answers on new and existing classifications were evaluated and compared statistically. Overall comparison between the two surveys was performed by generalized linear modeling. RESULTS: The proposed AE classification received superior evaluations in terms of consistency of reporting (P < .05) and potential for incorporation into existing quality-assurance framework (P < .05). Respondents gave a higher overall rating to the educational and research value of the new compared with the existing classification (P < .05). CONCLUSIONS: This study proposed an AE classification system that outperformed the existing SIR classification in the studied domains.

Standards of practice in interventional neuroradiology.

The growing importance of INR has resulted in the need to define and promote professional standards of clinical practice. Several professional organizations have published guidelines recently for the neurointerventional treatment of cerebrovascular diseases, including technical and personal recommendations, but detailed definitions of technical and organizational conditions needed for the safe and effective performance of such treatments are lacking. To fill this gap ESNR, ESMINT and the UEMS Division for Neuroradiology established a working group, to develop a consensus paper on "Standards of Practice in Interventional Neuroradiology". This document is the result of the Consensus Working Group and has following review gained approval by the Executive Boards of ESNR and ESMINT and by the members of the UEMS Division for Neuroradiology in 2017.

[ERCP procedures as a source of radiation risk to a single gastroenterologist]. / Zabieg ECPW jako zródlo narazenia radiacyjnego dla gastroenterologa.

BACKGROUND: One of the numerous sub-areas of interventional radiology is the use of X-rays in gastroenterology. X-ray fluoroscopy is applied in therapeutic procedures, including endoscopic retrograde cholangiopancreatography (ERCP) that is frequently performed. The ERCP procedure is aimed at imaging the pancreatic duct and biliary tracts. MATERIAL AND METHODS: In this paper radiation risk to the gastrenterologist performing ERCP procedures was investigated. The procedures were performed by a single gastroenterologist in the ERCP Laboratory, University Clinical Hospital Military Memorial Medical Academy - Central Veterans' Hospital in Lódz, Poland. The study comprised 2 series of measurements, one taken during the procedures with continuous fluoroscopy mode, the other during procedures with fluoroscopy in pulsed mode at a frequency of 3 pulses/s. Exposure parameters, anatomical data of patient and dose equivalents for the eyes, skin of the hand and the effective dose for whole body of the gastroenterologist were recorded during each procedure. RESULTS: The collected data cover 70 ERCP procedures - 40 procedures were controlled by continuous fluoroscopy and 30 by pulsed fluoroscopy. The results reveal that pulsed fluoroscopy makes it possible to reduce doses received by the gastroeneterologist from 45% to 60% compared to continuous fluoroscopy. CONCLUSIONS: Endoscopic retrograde cholangiopancreatography procedures can cause radiation risk to the gastroenterologist performing them. The use of continuous fluoroscopy can result in achieving an equivalent dose to eye lens nearly 20 mSv per year, i.e., the decreased annual limit recommended by the International Commission on Radiological Protection (ICRP).

Diagnostic reference levels and complexity indices in interventional radiology: a national programme.

OBJECTIVES: To propose national diagnostic reference levels (DRLs) for interventional radiology and to evaluate the impact of the procedural complexity on patient doses. METHODS: Eight interventional radiology units from Spanish hospitals were involved in this project. The participants agreed to undergo common quality control procedures for X-ray systems. Kerma area product (KAP) was collected from a sample of 1,649 procedures. A consensus document established the criteria to evaluate the complexity of seven types of procedures. DRLs were set as the 3rd quartile of KAP values. RESULTS: The KAP (3rd quartile) in Gy cm2 for the procedures included in the survey were: lower extremity arteriography (n = 784) 78; renal arteriography (n = 37) 107; transjugular hepatic biopsies (THB) (n = 30) 45; biliary drainage (BD) (n = 314) 30; uterine fibroid embolization (UFE) (n = 56) 214; colon endoprostheses (CE) (n = 31) 169; hepatic chemoembolization (HC) (n = 269) 303; femoropopliteal revascularization (FR) (n = 62) 119; and iliac stent (n = 66) 170. The complexity involved the increases in the following KAP factors from simple to complex procedures: THB x4; BD x13; UFE x3; CE x3; HC x5; FR x5 and IS x4. CONCLUSIONS: The evaluation of the procedure complexity in patient doses will allow the proper use of DRLs for the optimization of interventional radiology. KEY POINTS: • National DRLs for interventional procedures have been proposed given level of complexity • For clinical audits, the level of complexity should be taken into account. • An evaluation of the complexity levels of the procedure should be made.
