Communication: Preparing undergraduate radiation therapy students for initial clinical patient interactions.

INTRODUCTION: Radiation therapy students need to demonstrate appropriate communication skills when entering the clinical environment. To assist students with preparation for their first clinical placement a clinical reasoning module comprising theory and practical sessions was developed. This paper describes the module and presents the results of student evaluations. METHODS: The module consisted of lectures, observational role-play and participatory role-play. Students were ultimately tasked with providing information to a simulated patient (SP). Each student received feedback independently from the SP, peers and facilitator. At the conclusion of the module, students had the opportunity to provide feedback via an anonymous survey (8 Likert scale questions with space for written comment). Data was analysed both quantitatively and qualitatively. RESULTS: Four hundred and thirty seven students were enrolled in the course between 2008 and 2016 and the response rate of the survey was 93%. Even though most students reported some level of anxiety before and during the role-play sessions, the majority of students perceived all aspects of the module to be extremely/very useful. The most useful aspect of the module (Likert scale assessment) was the feedback provided by the SP. The two most important themes arising from the thematic analysis were gaining an understanding of the role of the radiation therapist and the complexities of patient interactions. CONCLUSION: Overall, the module was deemed successful with students becoming conscious of newly acquired clinical knowledge whilst acknowledging patient feelings during interactions. Collaborative critiquing contributed to students' ability to self-reflect to improve clinical interactions.

Males in mammography - A narrative review of the literature.

OBJECTIVE: There is a worldwide shortage of radiographers qualified to perform mammography. One solution is the employment of male radiographers. This literature review aims to assess the scope of information available that covers the prospect of males being employed in a breast screening setting. The review specifically focuses on the incidence of males employed as mammographers, training options and client perceptions of males performing breast imaging. KEY FINDINGS: Some countries employ male mammographers, though this is limited. There is contradictory information regarding the education of male radiography students in mammography. Several studies have indicated that clients of breast screening services would be open to males performing mammographic procedures, while others have reported strong opposition. The client's level of education, marital status and ethnicity affected their perception. CONCLUSION: The review has shown that the employment of male radiographers in mammography may work better in some countries and in some subgroup of clients than others. The review has also highlighted some of the barriers that needs to be overcome if the widespread inclusion of men in mammography were to be successfully implemented. These include the use of chaperones and providing client choice in the gender of radiographer.

Barriers and incentives for choosing to specialise in mammography- A survey of Australian undergraduate diagnostic radiography students.

INTRODUCTION: There is a projected shortage of radiographers working in breast screening in Australia. This study aimed to examine the perceived barriers and potential incentives among current undergraduate diagnostic radiography students to train, specialise and work in mammography. METHODS: A survey was undertaken to assess students' experience of six modalities during both University study and clinical practice. Students were asked to rank their priority of which they would want to specialise and if training and working in mammography was an option. RESULTS: From 248 students invited to participate, 101 students replied to the survey. Students indicated that they had been taught all modalities, however not all students had experienced them on clinical placement. Most students had observed or performed ultrasound (US) (90%, 90%), Computed Tomography (CT) (97%, 75%) and fluoroscopy (80%, 52%), though very few had experience of mammography (55%, 8%). US, CT, and MRI were the modalities that most students would like to specialise in. Male students reported being discriminated against working in mammography as this is "female only" work. CONCLUSION: Students have more clinical access to the major modalities of US, CT and MRI, and this appears to be a major factor into why student wish to specialise in these modalities. Role extension and higher wages were given as possible incentives that would make specialising in Mammography more appealing. The gender divide may have to be bridged to enable crucial recruitment as male students feel discriminated against.

Development and evaluation of a deep knowledge and skills based assignment: Using MRI safety as an example.

INTRODUCTION: Using magnetic resonance imaging (MRI) safety as an example, this paper discusses the development of an innovative multiple-step assignment task designed to increase student engagement and learning of important concepts. The paper also summarises student feedback about the assessment as well as thematic analysis of categories thought important to students. METHOD: A multi-step assignment was designed. Step one was the reading of a MRI safety article, step two was the construction and submission of 5 short answer questions believed to be important concepts of understanding and step three was the answering of 15 questions compiled from all student questions by the course coordinator. The motivation to answer the course coordinator compiled questions was the knowledge that five of these questions would be in the end of course examination. At the completion of the assignment, students were asked to complete an anonymous on-line questionnaire about the assignment task. Thematic analysis was used to gather data on what students perceived to be the most and least important concepts in the article. RESULTS: All students replying to the survey stated that they understood why MRI safety is an important topic and 79% reported this assignment was both a positive learning experience and provided understanding of the topic. Only 18% of students believed that they would have learned more through a formal lecture. CONCLUSION: The design of this assignment task can be used in any course, not just in medical radiation science, where student learning and understanding is critical.

Perceptions of Australian clients towards male radiographers working in breast imaging: Quantitative results from a pilot study.

AIM: Breast cancer is the second most common cause of cancer-related death in Australian women, therefore early breast cancer detection is essential. Female radiographers currently conduct breast screening in Australia; however there is a projected shortage. With many women already feeling apprehensive about attending a breast examination, possible proposals to fill this shortage must be carefully considered. Training male radiographers is one proposal however, this raises some gender concerns. This study aimed to pilot an investigation into whether it would change women's willingness to attend breast screening if conducted by a male radiographer. METHOD: A questionnaire completed by 146 women aged over 40 asked questions on attitude, initial reaction and how they would proceed if attended to by a male in three clinical situations (Mammography; Ultrasound and Breast Surgery). RESULTS: The results revealed that women would have had their mammogram (90%), ultrasound (95%) and surgery (100%) conducted by a male, though some would have preferred a female for mammography (25%), ultrasound (24%) and surgery (12%). A total of 9% of women agreed to the statement 'If there were male radiographers I would not return for another screening appointment' and 9% agreed to the statement 'if I heard there could be male radiographers it would change my opinion of Breast Screening for the worse'. CONCLUSIONS: This first Australian study investigating the perceptions of women to male radiographers in the breast screening arena suggest that a mix of male and female radiographers could be accommodated and indicates the need for a larger national survey.

Barriers and incentives for choosing to specialise in mammography: Qualitative analysis.

AIM: There is a projected shortage of radiographers working in breast screening and this study aimed to examine comments from open response questions from a mixed methods survey of current diagnostic radiography students on their perceptions of working in mammography. METHOD: The survey asked three open ended questions: Justification of choice of modality in which they would want to specialise, why they believed there was a shortage of radiographers working in breast screening and any other comment about mammography. RESULTS: Reasons given for specialising in any modality was interest, feature of a modality, amount of clinical exposure during the degree program, personal issues and career prospects. Few current diagnostic radiography students indicated that they would be interested in specialising in breast imaging. They considered there to be a shortage of radiographers as breast imaging was seen to be repetitive, high pressure, intimate and gender biased. Lack of education, clinical exposure, limited career prospects and low pay were also discussed. CONCLUSIONS: Increasing education to the modality during the degree, allowing males to be involved in breast imaging and promoting part-time work in mammography while also working in other modalities may alter the perception that mammography offers a limited career pathway.

Towards in vivo TLD dosimetry in mammography.

While phantoms are used for quality control assessment of the mammography unit, in vivo dose measurements are necessary to account for the variation in size and composition of the female breast. The use of thermoluminescent dosimeters (TLDs) in mammography has been limited due to TLD visibility. The aim of this current investigation was to access the suitability of a paper-thin LiF:Mg,Cu,P TLD (GR-200F) for in vivo dosimetric mammography measurements. The visibility of GR-200F has been directly compared with LiF:Mg,Cu,P TLDs (GR-200A) using a number of commercially available phantoms. The phantoms of thickness 2-5 cm were imaged over the range of tube potentials (24-28 kVp) used clinically. Both types of TLD were placed on the surface of the phantoms allowing assessment of visibility, entrance surface dose (ESD) and field homogeneity. In vivo assessment of ESD and visibility was also carried out on a volunteer undergoing a routine mammography examination. The positions of the GR-200F TLDs were not identified either on the image of the Leeds TOR(MAM) phantom or the patient mammograms. The average ESD for the Leeds phantom was 8.8 mGy, while the patient ESD was 13 mGy. It is now possible to perform in vivo measurements with the potential of increasing the accuracy of the doses measured for women that do not conform to a standard breast thickness or density.

Dose-area product readings for fluoroscopic and plain film examinations, including an analysis of the source of variation for barium enema examinations.

This paper contains the results of an investigation undertaken between 1994 and 1996 using dose-area product (DAP) meters for monitoring radiation doses from six types of simple examinations and seven types of complex examinations. Mean hospital DAP levels have been compared with National Reference Levels (NRL), with most departments producing levels lower than NRLs. DAP readings have allowed the proposal of provisional Reference Levels (RL) to be set for simple and complex examinations. The results were also compared with recently published data from the National Radiological Protection Board (NRPB), highlighting those hospitals which need to make changes in radiographic technique. The study of DAP reference doses also confirms that dose levels for complex investigations are clearly related to technique, in terms of screening time and number of films. Although the use of increased screening tube kilovoltage may be relevant, the overall effect is small. The results suggest that there is still a need to optimize the protocols for these examinations. The use of digital equipment has been shown to have a complex effect on dose, particularly in the case of investigations involving both films and fluoroscopy.

Influence of dose reduction recommendations on changes in chest radiography techniques.

A previous dosimetric study on chest radiography identified ways to reduce patient entrance surface dose (ESD). This present study was designed to monitor changes that had occurred in the use of applied potential and film-screen sensitivity, after a series of recommendations were issued. The study falls into two parts: (1) an assessment of the impact of the recommendations and (2) what factors were responsible for change. Where changes had occurred, exposure factors were collected for 30 patients per tube and the mean ESD was calculated for each tube. Intercomparison (r = 0.93, p < 0.001) was made between calculated and measured (TLDs) values of mean ESD for 10 X-ray units, to ensure that the calculated values provided accurate estimates of the new mean ESDs. 89% of units previously monitored for patient ESD now use average applied potentials greater than 90 kVp and 51% are using film-screen sensitivities of 400. The mean ESD has been reduced on average by 47%, from 0.15 mGy to 0.08 mGy. It has been estimated that the annual collective dose from diagnostic radiology procedures in 30 hospitals in the West Midlands has been reduced by a value in excess of 40 man Sv. Reasons for change could be attributed to some of the following factors: (a) a knowledge of dose levels in comparison with other centres; (b) personal contact with departments; (c) feedback in terms of results and dose savings and (d) positive encouragement to make changes.

Optimization of radiographic technique for chest radiography.

Over 1500 patients undergoing chest radiography in the West Midlands have been monitored for entrance surface doses using lithium borate thermoluminescent dosemeters. In total 63 X-ray tubes were monitored from 30 hospital departments. The mean patient entrance surface dose is 0.15 mGy, and the 75th percentile entrance surface dose is 0.18 mGy. A reference level of 0.18 mGy has been recommended for PA chest radiography in the West Midlands. Image quality has been assessed on patient radiographs. Departmental radiologists were responsible for assessing radiographs taken within their hospital. Independent analysis was performed by a control radiologist. Film-screen processor sensitivity has been assessed on 48 film-screen processor combinations. Significant differences were observed between the nominally quoted sensitivities and the measured sensitivities. Only 26% of systems produced measured sensitivities within 10% of the nominal values. A four variable regression model, explaining 78% of the variance, provided the best description for the variation in patient dose. These variables were actual sensitivity, applied potential, generator waveform and radiographic quality. Four recommendations have been made to lower patient doses; these are: (1) an increase in applied potential to a minimum of 90 kVp; (2) a film-screen sensitivity of 400; (3) optimization of processor performance and (4) regular radiological audits to reduce repeat rates to a level of 5%. If all of these recommendations are followed, an estimated overall entrance surface dose saving of 53% would result. Changing the applied potential alone will see the variation in the mean entrance surface dose from non-gridded systems reduce from a factor of 4 to a factor of 2.
