Large differences in education and training of radiographers in Europe and Central Asia: Results from an IAEA coordinated study

IntroductionEducation and training of radiographers is known to be diverse between countries and regions. Under an IAEA project, this work collected data on radiographer education for the Europe and Central Asia region with a particular focus on radiation protection gaps and potential actions.MethodsFollowing piloting, an electronic questionnaire was distributed to all national counterparts for the IAEA Technial Coopearation (TC) Europe region (n = 33 countries) and nominated national representatives. Contacts were additionally invited to a virtual workshop to discuss and rank common problems in education and training of radiographers and to propose potential solutions.ResultsResponses were received from 31 countries, including 14 from the European Union. Just over half of countries reported radiographer education being in higher education with 71% having program durations more than 3 years (range: 1 month-4 years). Programs included a spectrum of both clinical training and radiation protection hours with ten-fold variations noted across the region. Inclusion of core radiation protection topics within curricula varied similarly, as did radiographers’ clinical involvement in both justification and optimisation between countries. Workshop participants identified five common training problems, namely education availability, lack of standardisation, radiation protection course quality, teamwork problems and lack of equipment.ConclusionRadiographer education in the IAEA Europe region is heterogeneous with substantial differences in duration and quality of training programs between countries, which likely impact on quality of patient care delivered. Common problems have been identified and potential solutions proposed to focus quality improvement initiatives.Implications for practiceRadiographer education and training is diverse throughout the IAEA TC Europe region, with likely impacts on radiation protection practices applied. Clinical involvement of radiographers in justification and optimisation differs, potentially limiting adherence to radiation protection principles.     

Gynecological intrauterine brachytherapy training for radiation therapists: The development and implementation of a training program

PURPOSEGynecological brachytherapy (GynBT) is an important part of gynecological cancer management. At Olivia Newton-John Cancer Wellness & Research Centre (ONJCWRC), Melbourne, Australia, radiation therapists (RTs) are integral to the MRI adaptive GynBT program workflow. However, there is limited GynBT training available for RTs in Australia. A GynBT training program has been developed at ONJCWRC to meet this need and support RTs in becoming competent, proficient and confident in the various roles in GynBT. This is a preliminary report on the development and implementation of a credentialing program, providing a structured approach to GynBT training of RTs.METHODS AND MATERIALSA credentialing program was designed with modules and competency assessments to ensure efficiency and proficiency of RTs in the GynBT workflow. The program includes theoretical modules in anatomy, international GynBT guidelines, radiation safety and local protocols; and practical modules in equipment, ultrasound for GynBT, operating theatre procedures, MRI, contouring, applicator reconstruction, planning, quality assurance and treatment delivery. Learning strategies include self-directed learning, tutorials, practical sessions, and third-party courses. The program concludes with an exit examination assessing major competencies.RESULTSThe program was implemented in April 2018 with three RTs completing the program and passing the exit examination on first attempt. On post-program survey, the RTs felt the program was comprehensive, helping to build their confidence, and proficiency in GynBT.CONCLUSIONSA GynBT RT credentialing program was successfully developed and implemented to improve the quality of training at ONJCWRC. This program is mandatory for RTs joining the GynBT team. This program can provide a framework for implementation of GynBT training in other centers.     

RENEB – Running the European Network of biological dosimetry and physical retrospective dosimetry

Abstract

Purpose: A European network was initiated in 2012 by 23 partners from 16 European countries with the aim to significantly increase individualized dose reconstruction in case of large-scale radiological emergency scenarios.

Results: The network was built on three complementary pillars: (1) an operational basis with seven biological and physical dosimetric assays in ready-to-use mode, (2) a basis for education, training and quality assurance, and (3) a basis for further network development regarding new techniques and members. Techniques for individual dose estimation based on biological samples and/or inert personalized devices as mobile phones or smart phones were optimized to support rapid categorization of many potential victims according to the received dose to the blood or personal devices. Communication and cross-border collaboration were also standardized. To assure long-term sustainability of the network, cooperation with national and international emergency preparedness organizations was initiated and links to radiation protection and research platforms have been developed. A legal framework, based on a Memorandum of Understanding, was established and signed by 27 organizations by the end of 2015.

Conclusions: RENEB is a European Network of biological and physical-retrospective dosimetry, with the capacity and capability to perform large-scale rapid individualized dose estimation. Specialized to handle large numbers of samples, RENEB is able to contribute to radiological emergency preparedness and wider large-scale research projects.     

Safety in Radiation Oncology: The Role of International Initiatives by the International Atomic Energy Agency

The International Atomic Energy Agency (IAEA) has a wide range of initiatives that address the issue of safety. Quality assurance initiatives and comprehensive audits of radiotherapy services, such as the Quality Assurance Team for Radiation Oncology, are available through the IAEA. Furthermore, the experience of the IAEA in thermoluminescence dosimetric audits has been transferred to the national level in various countries and has contributed to improvements in the quality and safety of radiotherapy. The IAEA is also involved in the development of a safety reporting and analysis system (Safety in Radiation Oncology). In addition, IAEA publications describe and analyze factors contributing to safety-related incidents around the world. The lack of sufficient trained, qualified staff members is addressed through IAEA programs. Initiatives include national, regional, and interregional technical cooperation projects, educational workshops, and fellowship training for radiation oncology professionals, as well as technical assistance in developing and initiating local radiation therapy, safety education, and training programs. The agency is also active in developing staffing guidelines and encourages advanced planning at a national level, aided by information collection systems such as the Directory of Radiotherapy Centers and technical cooperation project personnel planning, to prevent shortages of staff. The IAEA also promotes the safe procurement of equipment for radiation therapy centers within a comprehensive technical cooperation program that includes clinical, medical physics, and radiation safety aspects and review of local infrastructure (room layout, shielding, utilities, and radiation safety), the availability of qualified staff members (radiation oncologists, medical physicists, and radiation technologists and therapists), as well as relevant imaging, treatment planning, dosimetry, and quality control items. The IAEA has taken the lead in developing a comprehensive program that addresses all of these areas of concern and is actively contributing to the national and international efforts to make radiation therapy safer in all settings, including resource-limited settings.     

Konzept und Durchführung der Modellprojekte für Mammographiescreening in Deutschland

The carriers of the German Statutory Health Care System have recognized that only mammographic screening according to the European Guidelines for the Quality Assurance of Mammography Screening will permit early detection of breast cancer with an acceptable risk/benefit ratio. In the German pilot projects, regional mammography screening programmes according to the European guidelines are being tested in the framework of the German health care system. The European guidelines require comprehensive quality assurance of all relevant steps in the chain of events involved in screening, from invitation on to therapy and follow-up. Such comprehensive quality assurance involves several medical specialities and other professional groups dealing with out-patient and in-patient health care and requires long-term cooperation with public institutions (population registries, cancer registries). The objective of the pilot projects is to test the organizational and legal conditions essential to introduction of a mammographic screening programme according to the European quality assurance guidelines in Germany.     

Importance of establishing radiation protection culture in Radiology Department

The increased use of ionization radiation for diagnostic and therapeutic purposes, the rapid advances in computed tomography as well as the high radiation doses delivered by interventional procedures have raised serious safety and health concerns for both patients and medical staff and have necessitated the establishment of a radiation protection culture (RPC) in every Radiology Department. RPC is a newly introduced concept. The term culture describes the combination of attitudes, beliefs, practices and rules among the professionals, staff and patients regarding to radiation protection. Most of the time, the challenge is to improve rather than to build a RPC. The establishment of a RPC requires continuing education of the staff and professional, effective communication among stakeholders of all levels and implementation of quality assurance programs. The RPC creation is being driven from the highest level. Leadership, professionals and associate societies are recognized to play a vital role in the embedding and promotion of RPC in a Medical Unit. The establishment of a RPC enables the reduction of the radiation dose, enhances radiation risk awareness, minimizes unsafe practices, and improves the quality of a radiation protection program. The purpose of this review paper is to describe the role and highlight the importance of establishing a strong RPC in Radiology Departments with an emphasis on promoting RPC in the Interventional Radiology environment.     

Report of an image quality and dose audit according to directive 97/43/Euratom at Spanish private radiodiagnostics facilities.

An audit of Spanish private medicine radiodiagnostics facilities has been carried out, based partly on Spanish legislation relating to European Directives on health protection against ionizing radiation risks in medical exposure. The study included an appraisal of infrastructure and equipment, and aspects of quality assurance and radiation protection, by means of data collected through surveys. Of the 51 centres audited, a sample of 24 X-ray rooms was chosen, then an external evaluation with regard to image quality and patient dose was performed, by an advisory board of radiologists and medical physicists. The methodology used was similar to that of the group of European Union experts in European dose evaluation and image quality trials. Chest, abdomen, lumbar spine and breast examinations were monitored. Doses were measured with thermoluminescent dosimeters. A third of the X-ray rooms evaluated reached or exceeded dose reference values, and in a third of the cases the image quality left considerable room for improvement. Breast and chest examinations showed themselves to be the hardest to perform, not only as a result of exceeding the reference doses, but also due to failure to meet good image quality standards.     

Quality assurance in x-ray diagnosis as specified in DIN 6868

Regular quality control and safety assurance in diagnostic radiological systems are included in the new radiation protection regulations. The monitoring program for both the equipment and the film processor can enable the user to recognize loss of quality early. Variables in the film processing unit can be differentiated from faults in the X-ray equipment more easily, including its use. The cost and time spent in setting up a safety assurance program are justified by the increase in quality.     

Pulmonary rehabilitation: an underutilized resource in primary COPD care

Pulmonary rehabilitation (PR) is an important component of chronic obstructive pulmonary disease (COPD) management. Physician use of PR for patients with COPD lags behind national and international guideline recommendations. In this article, we discuss the important components of PR, including exercise training, self-management education, and psychosocial and nutritional interventions, as based on the American Thoracic Society/European Respiratory Society and Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. We also discuss the potential benefits of PR, including reduction of respiratory symptoms, decreased disability, and increased participation in physical and social activities. Increased activity promotes independence, improves quality of life, and reduces the number of COPD exacerbations and hospitalizations. In all stages of COPD, PR has been shown to result in improved exercise tolerance, with reduced dyspnea and fatigue, although the greatest improvement has been seen in patients with GOLD stages II to IV. Pulmonary rehabilitation is now a well-recognized therapy that should be available to all patients with symptomatic COPD. To facilitate inclusion of PR in COPD management, primary care physicians need to recognize and diagnose COPD, and regularly decide when PR best fits in an individual's COPD treatment program.     

Radiation protection and quality assurance in diagnostic radiology--an IAEA coordinated research project in Asia and eastern Europe.

The International Atomic Energy Agency currently has two parallel Coordinated Research Projects (CRP) running in Asia and Eastern Europe. The main objective of the CRPs is to raise the level of awareness in participating countries about the need for radiation protection for patients undergoing diagnostic radiology procedures. This is to be achieved by first assessing the status quo in a sample of hospitals and X-ray rooms in each participating country. A program of optimization of radiation protection for patients is then introduced by means of a comprehensive quality assurance program and the implementation of appropriate dose reduction methods, taking into account clinical requirements for diagnostically acceptable images. Patient dose assessment and image quality assessment are to be performed both before and after the introduction of the quality assurance program. The CRP is divided into two phases--the first is concerned with conventional radiography, while the second involves fluoroscopy and computed tomography. The CRP is still running, restricting the scope of this paper to a discussion of the approach being taken with the project. The project will be completed in 1998, with analysis to follow.     

Cribado de cáncer de mama. Estado actual

The currently available scientific evidence attests that mammographic screening and quality treatment have been able to reduce mortality attributable to breast cancer. Although screening is not without risks, population-based screening has clear advantages over opportunistic detection. Following the Council of the European Union's “Recommendations on cancer screening”, all the regional Autonomous Communities in Spain have screening programs that, in general, follow the same guidelines. The “European guidelines for quality assurance in breast cancer screening and diagnosis” serve as a reference that provides an overview of all aspects of screening. To achieve the foreseen objectives for the reduction of the morbidity and mortality attributable to breast cancer, screening programs must fulfill the established quality criteria and guarantee that patients have access to the best treatment options.     

Proposed program guidelines for pregnant radiology residents: a project supported by the American Association for Women Radiologists and the Association of Program Directors in Radiology

RATIONALE AND OBJECTIVES: Written institutional policies governing radiation exposure and work responsibilities for pregnant radiology residents are not uniform and often are nonexistent. Standardized program guidelines would allow residents and program directors alike to prepare for a resident pregnancy with objectivity and consistency. MATERIALS AND METHODS: The American Association for Women Radiologists (AAWR) launched a task force to revisit guidelines for the protection of pregnant residents from radiation exposure during training. We conducted two surveys of the Association of Program Directors in Radiology (APDR) membership. Survey 1 was designed to learn about existing program and institutional policies and to assess the need for and interest in standardized guidelines that would address radiation exposure and work responsibilities for pregnant radiology residents. Based on those responses, we drafted a set of program guidelines incorporating policies contributed by responding program directors. Our follow-up APDR survey, survey 2, was conducted to determine opinions and acceptance of the drafted program guidelines. Each survey was analyzed by using a proportion of means test. RESULTS: Fifty-five of 156 program director APDR members (35%) responded to survey 1. Only half the respondents had formal written policies at their respective institutions. Review of submitted policies showed widely divergent opinions about appropriate policies for pregnant radiology residents. Most (34/52; 75%) supported the development of standardized guidelines. In survey 2, 38/73 responding APDR members (53%) offered their opinions and comments on our drafted guidelines. Approximately 90% agreement was catalogued on 13 of 18 items (72%); a majority (>60%) agreed on all points, even the most controversial points concerning fluoroscopy. CONCLUSION: A minority of radiology residency programs have written policies addressing pregnancy during training. With expressed support from a majority of responding program directors, we have developed and present here proposed program guidelines for pregnant radiology residents to serve as a framework for radiology residents and program directors alike.     

Blending work-integrated learning with distance education in an Australian radiation therapy advanced practice curriculum

Advanced practice for radiation therapists has been a part of the international landscape for several years; however formal implementation into the Australian health care system is yet to happen. Despite this, three short course radiation therapy advanced practitioner programs have been established by an Australian tertiary institution in response to clinical service needs at several organisations. This paper describes the rationale for curriculum design and development of the program materials, the small-scale implementation of the programs at pilot sites, and the evolution of the curriculum to be available to registered radiation therapists nationally. Each program has been designed around a specific clinical role, where flexibility of delivery to busy practitioners was central to the decision to offer them via distance education. The curriculum comprises theoretical units of study which run in parallel to and underpin clinical practice units, where advanced competence in the specific area of practice is overseen by an experienced radiation oncologist mentor. Given the nature of the disparate clinical services requiring an advanced radiation therapy practitioner, the workplace learning component of the course is individually negotiated at a local level. Outcomes suggest that the flexible clinically based training underpinned by a distance education academic curriculum is able to support the development of advanced radiation therapy practitioners responsive to local service need, and ultimately may improve the patient experience.     

Patient exposure during radiodiagnosis. The Nationwide Evaluation of X-ray Trends (NEXT) program in Italy

The aim of this paper is the critical analysis of the results obtained with the quality control program in X-ray diagnosis called NEXT (Nationwide Evaluation of X-ray Trends). It is also aimed at comparing the above results with guidelines and trends of international radiology, for both technical features and patient protection from radiations. The main purpose of patient protection is the reduction of unnecessary exposure through the optimization of radiodiagnostic procedures. In order to identify the fields requiring the application of specific quality control programs, the Istituto Superiore di Sanità, together with ENEA/DISP have been running the NEXT program in Italy since 1977. The program, through data collection and measurements in more than 2,500 radiologic units, allowed both state of the art and progress in radiodiagnostic practice to be studied over a long period of time. Data computation provides, for a standard patient, the skin entrance exposure and the main organ doses for the examinations which are most frequently performed. In this paper, the fundamentals of the NEXT program are reported and the most significant results are discussed, and compared, when possible, with the values recommended by international scientific organizations. The analysis of the results demonstrates a decreasing trend in patient exposure over the last years.     

Quality assurance and harmonisation of nuclear medicine investigations in Europe

A survey of all member societies of the European Association of Nuclear Medicine has shown that a satisfactory degree of harmonisation exists for the quality assurance of the preparation and handling of radio-pharmaceuticals and the performance of nuclear medicine instrumentation. However, variations were found in acquisition protocols, data analysis and the interpretation and presentation of clinical results. Harmonisation of these areas of a nuclear medicine investigation would help ensure the overall quality. A European initiative is proposed to collect and collate procedures in these areas in order to produce a reference framework of good practice for the acquisition, analysis and interpretation of nuclear medicine investigations. This would involve collaboration between national societies and exchange of information with and support from European organisations, taking into account relevant international activities. The reference framework should be compatible with quality management guidelines.     

Planungen der Deutschen Röntgengesellschaft und des Berufsverbandes zur Qualitätssicherung bei Mammographie

A high level of quality is an unequivocal prerequisite for obtaining the highest possible accuracy in symptomatic patients and for reproducing the results concerning mortality reduction, which were obtained in large screening trials. Present deficiencies in Germany are due to legal regulations, which have not been updated and which are thus below European standard. Furthermore the quality assurance program has not proven sufficiently effective for mammography. In order to promote mammographic quality assurance, the German Roentgen Society proposes an accreditation program. The accreditation, which concerns A.) mammographic technique and positioning and B.) mammographic reporting is not obligatory, but will allow acquisition of special official certificates, which may support the patients to find doctors who perform and read mammograms with high quality and expertise. The accreditation shall be performed by personnel and/or institutions who are specifically trained surveyed.     

Australian and New Zealand three-dimensional conformal radiation therapy consensus guidelines for prostate cancer

Three-dimensional conformal radiation therapy (3DCRT) has been shown to reduce normal tissue toxicity and allow dose escalation in the curative treatment of prostate cancer. The Faculty of Radiation Oncology Genito-Urinary Group initiated a consensus process to generate evidence-based guidelines for the safe and effective implementation of 3DCRT. All radiation oncology departments in Australia and New Zealand were invited to complete a survey of their prostate practice and to send representatives to a consensus workshop. After a review of the evidence, key issues were identified and debated. If agreement was not reached, working parties were formed to make recommendations. Draft guidelines were circulated to workshop participants for approval prior to publication. Where possible, evidence-based recommendations have been made with regard to patient selection, risk stratification, simulation, planning, treatment delivery and toxicity reporting. This is the first time a group of radiation therapists, physicists and oncologists representing professional radiotherapy practice across Australia and New Zealand have worked together to develop best-practice guidelines. These guidelines should serve as a baseline for prospective clinical trials, outcome research and quality assurance.     

The teaching of physics and related courses to residents in radiation oncology

A survey of physics and related teaching to radiation oncology residents in 21 Canadian cancer centres was undertaken in December 1987 and January 1988. This survey illustrates a very considerable variation in the formal teaching of physics to aspiring radiation oncologists with, for example, the number of hours offered ranging from 40 to 160 in those 10 centres which have a training program. It would appear to be of benefit to radiation oncology residents, those charged with teaching them, and the radiation oncology community as a whole, to develop specific guidelines for this aspect of resident education.     

Breast radiotherapy: an Australasian survey of current treatment techniques

Prior to the dissemination of evidence-based quality assurance guidelines, the Australian National Breast Cancer Centre Radiation Oncology Group conducted a process survey of breast radiotherapy treatment delivery throughout Australia. A process survey was conducted in August/September 1998. This survey comprised questions enquiring about treatment positioning, immobilization devices used, planning strategies, simulation and dose computation methods, treatment prescribing and quality assurance. The survey was sent to 123 Australian fellows of the Royal Australian and New Zealand College of Radiologists (RANZCR) and to the six directors of New Zealand radiation oncology departments. Fifty-eight questionnaires were returned of which 38 were received from individuals and 20 represented a reply from a department with a routine breast radiotherapy protocol (representing an average of 4.5 radiation oncologists per reply). The study identified great consistency between departments with respect to dose and fractionation for breast tangents. The study also identified some areas of treatment planning and delivery that varied between individuals or departments. These mainly reflected a lack of evidence in some areas of radiotherapy treatment delivery. The circulation of quality assurance guidelines will perhaps improve consistency of radiotherapy techniques in which studies have identified that technique changes improve outcome. This study identified that these areas include the taking of simulation and port films and the use of off-axis dosimetry. Further studies are required for areas of radiotherapy treatment delivery that have little evidence for or against their implementation.     

Mammographiescreening in Deutschland

Available data suggest that early detection of breast cancer by mammography screening can reduce mortality by about 25%. Intensified monitoring of women with a family history of breast cancer and regular general screening have recently been introduced in Germany. The screening program is expected to be fully established by 2008. Following its successful introduction (participation rates between 65 and 80%), the German screening program will be conducted and evaluated in accordance with the European guidelines. At least in the screening trials that were conducted prior to the now established screening program the quality criteria were more than fulfilled (e.g. cancer detection rate in Bremen 8.7, Wiesbaden 9.4, Weser-Ems region 8.3/1000). Additional parameters that can be taken into account for quality assurance are the overdiagnosis bias, lead time bias, length bias and selection bias. Moreover, there are some factors that are specific to the German program compared with the breast cancer screening programs already established in other countries. One of these is the intensified screening program for high-risk women (ca. 5% of all carcinomas) and as a result fewer women with an increased genetic risk of breast cancer will be represented in the general screening program. The German screening program involves only a few university centers and hospital-based physicians, which may have adverse effects on research and development as well as mammography training in the future. Therefore, the screening program should also provide for the investigation of new techniques or emerging techniques (e.g. CAD systems in screening mammography) in the future.
