A virtual reality environment for supporting mental wellbeing of students on remote clinical placement: A multi-methods evaluation.

BACKGROUND: Nursing and Allied Health Profession (NAHP) students undertake clinical placements as part of their pre-registration training. The remote nature of some placement sites, shiftwork and the emotionally challenging nature of the workload has led to mental wellbeing issues in many students. AIM: This project aimed to evaluate a novel 3D immersive virtual reality environment that supports mental wellbeing for NAHP students on clinical placement. It comprises a calming 3D tropical beach environment where students and tutors can meet for reflection and mutual support. DESIGN: A multi-methods design gathered quantitative impact data with validated measurement tools and qualitative output related to the lived experience of students. SETTINGS AND PARTICIPANTS: All 600 pre-registration NAHP students within the institution undertaking clinical placements were invited to participate, irrespective of mental wellbeing status. Students were randomly assigned to either a VR or Conventional cohort; all participants received the control support mechanism in a subsequent placement. METHODS: All participants completed an initial demographic and Readiness for Therapy survey followed by weekly Beck Anxiety and Depression Inventories during placement. All participants were invited to a semi-structured interview. RESULTS: Overall, 32 participants engaged with the application; although the VR cohort demonstrated improved scores on both Beck inventories, these were not statistically significant. This is probably due to the low response rate for the control cohort. A total of 15 interviews were conducted and several themes emerged from the data in relation. to both experiential outcomes (escapism, anonymity and sense of community) and instrumental outcomes (calming, mindfulness and combatting loneliness). CONCLUSIONS: User feedback indicates that a VR environment can provide a calming escape from the pressures and anxiety arising from clinical placement for healthcare students. The relaxing beach environment facilitated mindfulness meditation and the additional opportunities for pseudo-anonymous interactions with peers and tutors were wellreceived by students.

An unusual case of oedematous prostate volumetric changes observed over the course of radiotherapy on the MR linear accelerator.

INTRODUCTION: The integration of magnetic resonance (MR) imaging into radiotherapy through new technology, including the MR -linear accelerator (MRL), has allowed further advancements into image guided radiotherapy (IGRT). Better soft tissue visualisation has led to some unusual findings. CASE AND OUTCOMES: A patient with T1c N0 M0 prostate adenocarcinoma received 60Gy in 20# radiotherapy on the MRL. Radiotherapy planning (RTP) scans were completed on both CT and MR (using T2 and T1 weighted three-dimensional turbo spin echo sequences, reconstructed transaxially (TRA). The MR scans revealed atypical oedema in the right peripheral zone, visualised on T2-weighted (T2w) MR Images as an accumulation of high signal intensity fluid. Daily MRL treatment includes a (T2w 3D Tra) sequence with which oedematous changes could be monitored. The images demonstrated an increase in oedematous volume over fractions 1-10 causing the prostate contour variations from the initial planning scans. Despite the prostate volume variations PTV coverage was never breached and dose constraints were always met for both PTV and surrounding organs at risk (OAR's), excluding the need for oncologist input. A single Therapeutic Radiographer (RTT) experienced in MRL delivery, contoured the prostate and oedematous volumes on the radiotherapy plan (RTP) MR and all on-treatment MR images to assess change over the radiotherapy course. The initial volumes were 53.4 cm3 and 8.3 cm3 for the prostate plus oedema and oedema alone respectively. The most significant change was seen for both the prostate and oedema on fraction nine (68.0 cm3 and 10.1 cm3, respectively). Reductions were noted after this with final (fraction 20) volumes of 55.2 cm3 and 0.58 cm3 respectively. DISCUSSION: The ability to visualise prostatic oedema was new to the radiotherapy treatment team due to better soft tissue visualisation than standard radiotherapy. The results from contouring the prostate and oedema volumes confirmed radiographer observations and demonstrated how oedema impacted the overall prostate volume by quantifying the oedematous variations over time. The changes in oedema volume are presumed to be in response to radiotherapy. CONCLUSION: Further adaptive radiotherapy work-flow developments, utilising an "Adapt to Shape" model will allow real-time re-contouring of the prostate to ensure tumour control is not compromised. Further work investigating the frequency and impact of oedemotous changes to external beam prostate patients will help to inform practice.

Initial evaluation of a virtual reality bomb-defusing simulator for development of undergraduate healthcare student communication and teamwork skills.

Communication and teamworking skills are essential healthcare professional skills, yet undergraduates exhibit reluctance to engage with group work, especially in interprofessional groups. The aim of the study was to investigate whether a virtual reality bomb-defusing simulator would enable students to gain these skills through an enjoyable and challenging scenario without profession-specific knowledge. Students took it in turns to play the role of the 'Defuser' immersed in a headset, while the rest of the group were 'Experts' with a printed manual, but no sight of the bomb. The task challenged students to relay obscure symbols and instructions to each other rapidly and effectively. A subsequent focus group explored the impact of the simulation on students' perceived learning, engagement and communication skills. The focus group of five multiprofessional healthcare students reported high levels of engagement and satisfaction while highlighting value in developing communication and teamwork. The simulator nurtured initial group dynamics and team bonding. Evaluation data indicated that the intervention facilitated cooperation, team bonding and the development of good communication skills. This method of encouraging communication would fit well into an interprofessional learning session as a useful tool ahead of more technical and clinically based group work. The focus group of five multiprofessional healthcare students reported high levels of engagement and satisfaction while highlighting value in developing communication and teamwork. The simulator nurtured initial group dynamics and team bonding.

Artificial Intelligence in Radiotherapy: A Philosophical Perspective.

The increasing uptake of machine learning solutions for segmentation and planning leaves no doubt that artificial intelligence (AI) will soon be providing input into a range of radiotherapy procedures. Although this promises to deliver increased speed and accuracy, the future role of AI in relation to radiotherapy should be thought through carefully. There is currently a gap between published developments and widespread adoption, which provides some space to prepare the workforce and to consider the implications on practice. It is rare to find philosophical input into a medical journal, but the advent of AI makes this perspective increasingly important. Philosophical insight can help explore the potential impact of AI, in particular, on human creativity and oversight. Without this perspective, we run the risk of focusing solely on the immediate logistical impact on patients and departments. This commentary identifies three key aspects of radiotherapy that the authors feel would suffer most under AI control: creativity, innovation, and patient safety, which all demand uniquely human attributes. The article also provides insight from a philosophical perspective with regard to human consciousness, ethics, and empathy. Philosophically we should, perhaps, retain ethical concerns about the widening role of AI in radiotherapy beyond simple quantitative interpretation and image processing. As developments continue, we have time to determine how our roles will evolve and to establish a framework for ensuring appropriate human input into patient care. Most importantly, we must start to embed a philosophical approach to adoption of AI technology from the outset if we are to prepare ourselves for the challenge that lies ahead.

A Systematic Review of the Role of Penile Rehabilitation in Prostate Cancer Patients Receiving Radiotherapy and Androgen Deprivation Therapy.

INTRODUCTION/BACKGROUND: Treatment-induced erectile dysfunction (ED) is a common side effect of radiotherapy and androgen deprivation therapy (ADT) that impacts on patient quality of life. Penile rehabilitation interventions including pharmacologic and physical therapies aim to reduce the impact of ED. Despite The National Institute for Health and Care Excellence guidelines recommending access to ED services, penile rehabilitation is not widely discussed or implemented. This systematic review aimed to appraise the evidence base for penile rehabilitation and identify evidence-based recommendations for practice. METHODS: A systematic review of the evidence base was undertaken using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The Scopus and Medline (EBSCO) databases were searched for articles relevant to penile rehabilitation interventions for prostate radiotherapy patients. Study quality was graded using the Oxford Levels of Evidence and the Scottish Intercollegiate Guidelines Network. RESULTS: This study identified 19 articles on penile rehabilitation in prostate radiotherapy patients, consisting of eight randomized controlled trials, three systematic reviews, and eight case studies. Findings confirmed the value of early use of phosphodiesterase type 5 inhibitors. DISCUSSION: Despite the range of available physical and pharmaceutical interventions, relevant research focussed solely on the use of phosphodiesterase type 5 inhibitors. Themes from the reviewed articles indicated that timing of intervention was important with early on-going dosage most useful. There was also an identified need for ongoing prophylactic use during ADT. Evidence, in general, was of low quality and based on quantitative data only. CONCLUSION: Additional research into the wider range of penile rehabilitation interventions is urgently required to ensure patients have access to those therapies that are most appropriate for them. A paradigm shift toward qualitative research in the field of penile rehabilitation for prostate cancer patients treated with radiotherapy and ADT may be of value in future studies.

Internationalising Research Methods Teaching of Undergraduate Health Professionals.

OBJECTIVE: The project aims were: (1) identifying the pedagogical impact of collaborative student experience on student understanding of research methods and (2) evaluating the perceived value of providing students with an international perspective on their professional practice. METHODS: Student cohorts from year 1 of the University of Liverpool (UoL) (n = 80) and year 2 of the Royal Melbourne Institute of Technology University (RMIT) (n = 128) undergraduate Medical Radiation Science degree programmes participated in the intervention as part of their teaching. Students were tasked with designing, deploying, and analysing data from survey-based research projects and invited to provide feedback via an anonymous and voluntary online survey (UoL students) or an equivalent paper-based survey (RMIT students), comprising both quantitative (Likert) and qualitative (open) questions. RESULTS: Responses were received from 83% of RMIT and 31% of UoL students. Over 42% of respondents enjoyed the opportunity to interact with overseas peers, while 14.7% did not; 40% of respondents felt the intervention helped in their understanding of research methods, whilst 28% indicated it had not. The main positive themes were learning the research process, team working skills, networking opportunities, and understanding cultural differences. Interpreting data were invaluable; only a minority valued the engagement with their overseas counterparts. There was poor engagement with social media. CONCLUSIONS: Students reported clear value of the innovation for learning research skills and process. The extent of research skills learning supports changes in research activity and culture in the past 10 years. With internationalisation becoming increasingly important in today's health care economy, the degree to which the students identified this aspect of the research as a key learning point highlights the benefits of the active approach. The negative appraisal of the social media support was interpreted as a response to the platform (WhatsApp) and privacy issues with sharing phone numbers.

The development and implementation of a performance appraisal framework for radiation therapists in planning and simulation.

It is a challenge for radiation therapists (RTs) to keep pace with changing planning technology and techniques while maintaining appropriate skills levels. The ability of individual RTs to meet the demands of this constantly changing practice can only be assured through establishing clearly defined standards for practice and a systematic process for providing feedback on performance. Investigation into existing models for performance appraisal produced minimal results so a radiation therapy-specific framework was developed. The goal for this initiative was to establish a framework that would reflect the complexity of practice and provide a clear measure of performance against them. This paper outlines the implementation of this framework into practice and discusses some lessons learned in the process. The framework was developed and implemented in six stages: (1) project team, (2) scope, (3) dosimetry pilot, (4) staff consultation, (5) finalisation and implementation and (6) future development and evaluation. Both cultural and organisational obstacles needed to be addressed before this framework could be successfully introduced. Even though this slowed progress, addressing these obstacles during the development process was essential to the success of this framework. The incremental approach provided the opportunity for each aspect to be tested and the development of subsequent stages to be informed by lessons learned during the previous one. This approach may be beneficial when developing and implementing projects involving performance appraisal to promote consistency, fairness and quality.

Salute to the sun: a new dawn in yoga therapy for breast cancer.

INTRODUCTION: Interest in the application of yoga for health benefits in western medicine is growing rapidly, with a significant rise in publications. The purpose of this systematic review is to determine whether the inclusion of yoga therapy to the treatment of breast cancer can improve the patient's physical and psychosocial quality of life (QoL). METHODS: A search of peer reviewed journal articles published between January 2009 and July 2014 was conducted. Studies were included if they had more than 15 study participants, included interventions such as mindfulness-based stress reduction (MBSR) or yoga therapy with or without comparison groups and had stated physical or psychological outcomes. RESULTS: Screening identified 38 appropriate articles. The most reported psychosocial benefits of yoga therapy were anxiety, emotional and social functioning, stress, depression and global QoL. The most reported physical benefits of yoga therapy were improved salivary cortisol readings, sleep quality and lymphocyte apoptosis. Benefits in these areas were linked strongly with the yoga interventions, in addition to significant improvement in overall QoL. CONCLUSION: The evidence supports the use of yoga therapy to improve the physical and psychosocial QoL for breast cancer patients with a range of benefits relevant to radiation therapy. Future studies are recommended to confirm these benefits. Evidence-based recommendations for implementation of a yoga therapy programme have been derived and included within this review. Long-term follow-up is necessary with these programmes to assess the efficacy of the yoga intervention in terms of sustainability and patient outcomes.

Qualitative Evaluation of a Novel 3D Volumetric Radiotherapy Segmentation Tool.

INTRODUCTION: A novel 3D volumetric segmentation tool allows the user to outline using a small number of points on a range of planes. Unique 3D volumetric "sculpting" tools enable editing of the resulting structures across multiple slices concurrently. This article reports the results of radiation oncologists' preclinical evaluation of the tool. METHODS: Three clinicians outlined prostate and seminal vesicles on 14 data sets using the traditional slice-by-slice method and the new 3D tool. The project gathered focus-group feedback to gather rich data relating to clinician perceptions of the new 3D outlining paradigm. Emergent themes were identified and categorised for discussion. RESULTS: Radiation oncologists reported high levels of satisfaction with the outlines arising from both paradigms. The volumetric sculpting was a challenge, but participants enjoyed using points in orthogonal planes and felt that the paradigm had potential value in terms of speed and smooth volume creation. CONCLUSION: This study has demonstrated that a 3D volumetric outlining system is felt to have potential value by radiation oncologists for accelerating clinician-directed prostate and seminal vesicle segmentation. The new tool was well-received and reported to be capable of producing very rapid and smooth volumes. The novelty of the approach required significant training input and a radically different approach of minimal point placement. Further testing of this software with a less time-poor cohort may be indicated to gain reliable quantitative data relating to the impact on segmentation time.

Evaluation of a performance appraisal framework for radiation therapists in planning and simulation.

INTRODUCTION: Constantly evolving technology and techniques within radiation therapy require practitioners to maintain a continuous approach to professional development and training. Systems of performance appraisal and adoption of regular feedback mechanisms are vital to support this development yet frequently lack structure and rely on informal peer support. METHODS: A Radiation Therapy Performance Appraisal Framework (RT-PAF) for radiation therapists in planning and simulation was developed to define expectations of practice and promote a supportive and objective culture of performance and skills appraisal. Evaluation of the framework was conducted via an anonymous online survey tool. Nine peer reviewers and fourteen recipients provided feedback on its effectiveness and the challenges and limitations of the approach. RESULTS: Findings from the evaluation were positive and suggested that both groups gained benefit from and expressed a strong interest in embedding the approach more routinely. Respondents identified common challenges related to the limited ability to implement suggested development strategies; this was strongly associated with time and rostering issues. CONCLUSIONS: This framework successfully defined expectations for practice and provided a fair and objective feedback process that focussed on skills development. It empowered staff to maintain their skills and reach their professional potential. Management support, particularly in regard to provision of protected time was highlighted as critical to the framework's ongoing success. The demonstrated benefits arising in terms of staff satisfaction and development highlight the importance of this commitment to the modern radiation therapy workforce.

A virtual environment for medical radiation collaborative learning.

A software-based environment was developed to provide practical training in medical radiation principles and safety. The Virtual Radiation Laboratory application allowed students to conduct virtual experiments using simulated diagnostic and radiotherapy X-ray generators. The experiments were designed to teach students about the inverse square law, half value layer and radiation protection measures and utilised genuine clinical and experimental data. Evaluation of the application was conducted in order to ascertain the impact of the software on students' understanding, satisfaction and collaborative learning skills and also to determine potential further improvements to the software and guidelines for its continued use. Feedback was gathered via an anonymous online survey consisting of a mixture of Likert-style questions and short answer open questions. Student feedback was highly positive with 80 % of students reporting increased understanding of radiation protection principles. Furthermore 72 % enjoyed using the software and 87 % of students felt that the project facilitated collaboration within small groups. The main themes arising in the qualitative feedback comments related to efficiency and effectiveness of teaching, safety of environment, collaboration and realism. Staff and students both report gains in efficiency and effectiveness associated with the virtual experiments. In addition students particularly value the visualisation of "invisible" physical principles and increased opportunity for experimentation and collaborative problem-based learning. Similar ventures will benefit from adopting an approach that allows for individual experimentation while visualizing challenging concepts.

Practice patterns of radiation therapy technology in Australia: results of a national audit.

INTRODUCTION: This article presents the results of a single-day census of radiation therapy (RT) treatment and technology use in Australia. The primary aim of the study was to ascertain patterns of RT practice and technology in use across Australia. These data were primarily collated to inform curriculum development of academic programs, thereby ensuring that training is matched to workforce patterns of practice. METHODS: The study design was a census method with all 59 RT centres in Australia being invited to provide quantitative summary data relating to patient case mix and technology use on a randomly selected but common date. Anonymous and demographic-free data were analysed using descriptive statistics. RESULTS: Overall data were provided across all six Australian States by 29 centres of a possible 59, yielding a response rate of 49% and representing a total of 2743 patients. Findings from this study indicate the increasing use of emerging intensity-modulated radiotherapy (IMRT), image fusion and image-guided radiation therapy (IGRT) technology in Australian RT planning and delivery phases. IMRT in particular was used for 37% of patients, indicating a high uptake of the technology in Australia when compared to other published data. The results also highlight the resource-intensive nature of benign tumour radiotherapy. CONCLUSIONS: In the absence of routine national data collection, the single-day census method offers a relatively convenient means of measuring and tracking RT resource utilisation. Wider use of this tool has the potential to not only track trends in technology implementation but also inform evidence-based guidelines for referral and resource planning.

Factors influencing radiation therapy student clinical placement satisfaction.

INTRODUCTION: Radiation therapy students at Queensland University of Technology (QUT) attend clinical placements at five different clinical departments with varying resources and support strategies. This study aimed to determine the relative availability and perceived importance of different factors affecting student support while on clinical placement. The purpose of the research was to inform development of future support mechanisms to enhance radiation therapy students' experience on clinical placement. METHODS: This study used anonymous Likert-style surveys to gather data from years 1 and 2 radiation therapy students from QUT and clinical educators from Queensland relating to availability and importance of support mechanisms during clinical placements in a semester. RESULTS: The study findings demonstrated student satisfaction with clinical support and suggested that level of support on placement influenced student employment choices. Staff support was perceived as more important than physical resources; particularly access to a named mentor, a clinical educator and weekly formative feedback. Both students and educators highlighted the impact of time pressures. CONCLUSIONS: The support offered to radiation therapy students by clinical staff is more highly valued than physical resources or models of placement support. Protected time and acknowledgement of the importance of clinical education roles are both invaluable. Joint investment in mentor support by both universities and clinical departments is crucial for facilitation of effective clinical learning.

The development and evaluation of a medical imaging training immersive environment.

INTRODUCTION: A novel realistic 3D virtual reality (VR) application has been developed to allow medical imaging students at Queensland University of Technology to practice radiographic techniques independently outside the usual radiography laboratory. METHODS: A flexible agile development methodology was used to create the software rapidly and effectively. A 3D gaming environment and realistic models were used to engender presence in the software while tutor-determined gold standards enabled students to compare their performance and learn in a problem-based learning pedagogy. RESULTS: Students reported high levels of satisfaction and perceived value and the software enabled up to 40 concurrent users to prepare for clinical practice. Student feedback also indicated that they found 3D to be of limited value in the desktop version compared to the usual 2D approach. A randomised comparison between groups receiving software-based and traditional practice measured performance in a formative role play with real equipment. The results of this work indicated superior performance with the equipment for the VR trained students (P = 0.0366) and confirmed the value of VR for enhancing 3D equipment-based problem-solving skills. CONCLUSIONS: Students practising projection techniques virtually performed better at role play assessments than students practising in a traditional radiography laboratory only. The application particularly helped with 3D equipment configuration, suggesting that teaching 3D problem solving is an ideal use of such medical equipment simulators. Ongoing development work aims to establish the role of VR software in preparing students for clinical practice with a range of medical imaging equipment.

Clinical perceptions of radiation therapy undergraduate competency standards.

INTRODUCTION: The multifactorial nature of clinical skills development makes assessment of undergraduate radiation therapist competence level by clinical mentors challenging. A recent overhaul of the clinical assessment strategy at Queensland University of Technology has moved away from the high-stakes Objective Structured Clinical Examination (OSCE) to encompass a more continuous measure of competence. This quantitative study aimed to gather stakeholder evidence to inform development of standards by which to measure student competence for a range of levels of progression. METHODS: A simple anonymous questionnaire was distributed to all Queensland radiation therapists. The tool asked respondents to assign different levels of competency with a range of clinical tasks to different levels of student. All data were anonymous and was combined for analysis using Microsoft Excel. RESULTS: Feedback indicated good agreement with tasks that specified the amount of direction required and this has been incorporated into the new clinical achievements record that the students need to have signed off. Additional puzzling findings suggested higher expectations with planning tasks than with treatment-based tasks. CONCLUSION: The findings suggest that the amount of direction required by students is a valid indicator of their level and has been adopted into the clinical assessment scheme. Further work will build on this to further define standards of competency for undergraduates.

A snapshot of radiation therapy techniques and technology in Queensland: An aid to mapping undergraduate curriculum.

INTRODUCTION: Undergraduate students studying the Bachelor of Radiation Therapy at Queensland University of Technology (QUT) attend clinical placements in a number of department sites across Queensland. To ensure that the curriculum prepares students for the most common treatments and current techniques in use in these departments, a curriculum matching exercise was performed. METHODS: A cross-sectional census was performed on a pre-determined "Snapshot" date in 2012. This was undertaken by the clinical education staff in each department who used a standardized proforma to count the number of patients as well as prescription, equipment, and technique data for a list of tumour site categories. This information was combined into aggregate anonymized data. RESULTS: All 12 Queensland radiation therapy clinical sites participated in the Snapshot data collection exercise to produce a comprehensive overview of clinical practice on the chosen day. A total of 59 different tumour sites were treated on the chosen day and as expected the most common treatment sites were prostate and breast, comprising 46% of patients treated. Data analysis also indicated that intensity-modulated radiotherapy (IMRT) use is relatively high with 19.6% of patients receiving IMRT treatment on the chosen day. Both IMRT and image-guided radiotherapy (IGRT) indications matched recommendations from the evidence. CONCLUSION: The Snapshot method proved to be a feasible and efficient method of gathering useful data to inform curriculum matching. Frequency of IMRT use in Queensland matches or possibly exceeds that indicated in the literature. It is recommended that future repetition of the study be undertaken in order to monitor trends in referral patterns and new technology implementation.
