Introduction: The magnitude and impact of rotational error is unclear in rectal cancer radiation therapy. This study evaluates rotational errors in rectal cancer patients, and investigates the feasibility of planning target volume (PTV) margin reduction to decrease organs at risk (OAR) irradiation. Methods: In this study, 10 patients with rectal cancer were retrospectively selected. Rotational errors were assessed through image registration of daily cone beam computed tomography (CBCT) and planning CT scans. Two reference treatment plans (TPR) with PTV margins of 5 mm and 10 mm were generated for each patient. Pre-determined rotational errors (±1°, ±3°, ±5°) were simulated to produce six manipulated treatment plans (TPM) from each TPR. Differences in evaluated dose-volume metrics between TPR and TPM of each rotation were compared using Wilcoxon Signed-Rank Test. Clinical compliance was investigated for statistically significant dose-volume metrics. Results: Mean rotational errors in pitch, roll and yaw were -0.72 ± 1.81°, -0.04 ± 1.36° and 0.38 ± 0.96° respectively. Pitch resulted in the largest potential circumferential displacement of clinical target volume (CTV) at 1.42 ± 1.06 mm. Pre-determined rotational errors resulted in statistically significant differences in CTV, small bowel, femoral heads and iliac crests (P < 0.05). Only small bowel and iliac crests failed clinical compliance, with majority in the PTV 10 mm margin group. Conclusion: Rotational errors affected clinical compliance for OAR dose but exerted minimal impact on CTV coverage even with reduced PTV margins. Both PTV margin reduction and rotational correction decreased irradiated volume of OAR. PTV margin reduction to 5 mm is feasible, and rotational corrections are recommended in rectal patients to further minimise OAR irradiation.

Introduction: Adaptive communication is an essential requirement to deliver quality patient-centred care. Determining patients' informational needs and acting on the needs are skills radiation therapists (RTs) employ daily with patients. Learning health literacy (HL) strategies to assist with the informational delivery provides RTs with options to improve patients' understanding of vital radiotherapy treatment information or tasks. This research investigates the lived experiences of RTs from the Illawarra and Shoalhaven Cancer Care Centres in Australia using HL strategies during patient interactions after undertaking HL training workshops. Methods: An interpretative phenomenological analysis (IPA) approach was used. Audio-recorded semi-structured interviews were conducted with six RTs. Two reviewers analysed each interview script separately before discussing and constructing substantive and sub-themes. Results: Four substantive themes were constructed: RT personal attitudes and responses to HL, HL strategies used by RTs, patient associated HL needs and barriers when addressing patient HL needs. RTs were either person- or process-focussed during patient interactions. It was identified that information is provided to patients according to how RTs themselves like to learn new information. Conclusion: This research has allowed an opportunity to inquire into the lived experiences of RTs implementing HL strategies when providing information to patients. While RTs may be person or process-focussed, the patient's needs are always prioritised when providing information, which ultimately results in patient understanding and increased engagement.

Introduction: Radiation therapists must possess adaptable communication skills to manage patient-centred care and provide required technical information. Adaptive communication is also an expectation of undergraduate students to gain registration in Australia. The University Of Newcastle's Clinical Reasoning Module (CRM) prepares first-year radiation therapy students for clinical interactions. This research aims to reveal the lived experience of students after completing their first clinical placement. Methods: An interpretative phenomenological analysis (IPA) approach was the chosen methodology. Audio-recorded semi-structured interviews were conducted with first-year students who had completed the CRM and attended their first placement. Two independent reviewers analysed each data set separately before discussing and agreeing on, and arranging themes into clusters to reveal substantive and sub-themes. Results: Four students were interviewed. Five substantive themes were revealed; 'making sense of the CRM', 'the inner self',' the art of communication', 'the student as a learner' and 'clinical work'. Students' varied clinical experiences were evident, and the interviews allowed a de-brief mechanism. Students related the CRM to the clinical environment and revealed unexpected reactions and emotional responses during their placement. Examples include disclosing the reluctance of patients to interact and talking about dying, which became their new normal. Conclusion: This review allowed an opportunity to inquire into the lived experiences of radiation therapy students navigating their way through the clinical environment. Differences between student's emotional intelligence and level of communication reflected their ability to make sense of their experiences in the clinical setting. Implications for practice: While students appeared satisfied with the CRM in preparing them for clinical placement, providing regular de-brief sessions and reviewing clinical practice guidelines to better prepare for psycho-social issues encountered is recommended for overall student well-being.

Introduction: Conventionally computed tomography (CT) has been used to delineate target volumes in radiotherapy; however, magnetic resonance imaging (MRI) is being continually integrated into clinical practice; therefore, the investigation into targets derived from MRI is warranted. The purpose of this study was to evaluate the impact of imaging modality (MRI vs. CT) and patient positioning (supine vs. prone) on planning target volumes (PTVs) and organs at risk (OARs) for partial breast irradiation (PBI). Methods: A retrospective data set, of 35 patients, was accessed where each patient had undergone MRI and CT imaging for tangential whole breast radiotherapy in both the supine and prone position. PTVs were defined from seroma cavity (SC) volumes delineated on each respective image, resulting in 4 PTVs per patient. PBI plans were generated with 6MV external beam radiotherapy (EBRT) using the TROG 06.02 protocol guidelines. A prescription of 38.5Gy in 10 fractions was used for all cases. The impact analysis of imaging modality and patient positioning included dose to PTVs, and OARs based on agreed criteria. Statistical analysis was conducted though Mann¿Whitey U, Fisher's exact and chi-squared testing (P¿<¿0.005). Results: Twenty-four patients were eligible for imaging analysis. However, positioning analysis could only be investigated on 19 of these data sets. No statistically significant difference was found in OAR doses based on imaging modality. Supine patient position resulted in lower contralateral breast dose (0.10Gy¿±¿0.35 vs. 0.33Gy¿±¿0.78, p¿=¿0.011). Prone positioning resulted in a lower dose to ipsilateral lung volumes (10.85Gy¿±¿11.37 vs. 3.41Gy¿±¿3.93, P¿=¿<0.001). Conclusions: PBI plans with PTVs derived from MRI exhibited no clinically significant differences when compared to plans created from CT in relation to plan compliance and OAR dose. Patient position requires careful consideration regardless of imaging modality chosen. Although there was no proven superiority of MRI derived target volumes, it indicates that MRI could be considered for PBI target delineation.

Gastrointestinal (GI) toxicities are common in patients receiving radiotherapy (RT) to the pelvis. This systematic review aims to evaluate the effectiveness of nutritional interventions involving dietary counselling (DC) on GI toxicities in patients receiving pelvic RT. The search method entailed two phases to retrieve studies. Articles from a previous Cochrane review by Lawrie et al. 2018 were assessed for inclusion. An updated systematic search was then conducted to retrieve articles published between 2013 and 2020 from five electronic databases (MEDLINE, EMBASE, CINAHL, CENTRAL and Scopus). The inclusion criteria entailed randomised controlled trials involving adults =18¿years, undergoing curative pelvic RT, receiving a nutritional intervention involving DC with or without supplements. DC was defined as written or face-to-face dietary advice provided before or during RT. Outcomes included GI toxicities reported by validated assessment tools. The Academy of Nutrition and Dietetics Quality Criteria Checklist was utilised to assess quality and risk of bias. Of 1922 studies retrieved, 12 articles encompassing 11 individual RCTs were included. Seven studies included a supplement in addition to DC. Supplements included probiotics, prebiotics, probiotic + soluble fibre, high protein liquid supplement and fat emulsion. Of the 11 studies, one involved individualised DC, and the remaining studies prescribed consumption or avoidance of fats, fibre, lactose, protein and FODMAP. The most common toxicities reported were diarrhoea (n¿=¿11), pain/cramping (n¿=¿9) and bloating/flatulence (n¿=¿5). Three studies stated an improvement in diarrhoea incidence. Results varied between studies. Further quality studies are required to assess the effectiveness of DC, in particular individualised DC on GI toxicities in patients receiving pelvic RT.

Radiation therapist (RT) communication plays an essential part of patient-centred care in achieving better patient outcomes within radiation oncology. Patients present from a range of social circumstances, education levels and cultural backgrounds, all of which may significantly impact their level of health literacy (HL). Using literature sourced from databases such as EMCare Nursing & Allied Health Database, MEDLINE(R) and APA PsycInfo, this narrative review explores HL definitions, international comparison rates and indications of individual low HL. It also reviews HL assessments as well as exploring enablers and barriers to HL from the RT perspective. Strategies from both the individual or organisational perspective are provided for RTs to begin or continue their HL interest. By educating the radiation therapy profession about health literacy and making small changes in interpersonal interactions, there is the opportunity to impact patients' experiences and outcomes significantly.

Introduction: Chemoradiotherapy (CRT) is the standard treatment for locally advanced cervical and vaginal cancer. It is associated with high haematological toxicity (HT) that can lead to treatment interruptions and cancelled chemotherapy cycles, reducing the potential effectiveness of this regimen. Bone marrow sparing (BMS) utilising volumetric modulated arc therapy (VMAT) is one method to reduce dose to the active bone marrow (ABM) so that HT rates are reduced. The aim of this paper was to assess whether BMS-VMAT can effectively spare the ABM whilst maintaining clinically acceptable target and organ-at-risk (OAR) doses. Methods: Twenty gynaecological cancer patients treated with definitive CRT at the Liverpool/Macarthur Cancer Therapy centres between 2015 and 2020 were retrospectively included. ABM was delineated based on fluorodeoxyglucose positron emission tomography (FDG-PET) imaging. Weekly blood tests and ABM dose parameters at the V10Gy, V20Gy, V30Gy, V40Gy and Dmean were assessed on original plans for any potential correlation with grade 2+ HT. Replanned with VMAT for BMS, various dose parameters were compared with the original plan to assess for any significant differences. Results: Active bone marrow doses were significantly reduced (P¿<¿0.001 for all parameters) in BMS-VMAT plans, and significant improvements in target and OAR coverage were found compared with the original plans. Compared with VMAT only, target and OARs were comparable. No significant correlations between HT and ABM doses were found. Conclusion: Bone marrow sparing volumetric modulated arc therapy can significantly reduce dose to the active bone marrow whilst maintaining acceptable target and OAR doses. Future prospective trials are needed to evaluate the clinical impact of BMS on toxicity and compliance.

Introduction: Low health literacy can inhibit patients' understanding of radiation therapy (RT) procedures. An objective of this research was to develop training to educate Australian radiation therapists (RTTs) about tools that support low health literacy patients, namely plain language and the Teach Back method (TBM). Perceptions, clinical use of these tools and confidence levels (pre and post training) in occupational scenarios were evaluated. Methods: RTTs attended two workshops one week apart. Three anonymous surveys (before the first workshop, immediately after the second and three months post workshops) were completed. Quantitative analysis included weighted sum averages of confidence levels and chi-square analysis. Results: At baseline, 56% of participants had heard of 'health literacy', 93% 'plain language', while 26% knew about TBM. Confidence levels increased after the workshops, with improvement of confidence demonstrating significance (p < 0.05) in 3/7 scenarios. The use of 'plain language' assessed on the third survey during every interaction was higher than that anticipated by participants on the second survey (46% vs 39%), while the TBM was utilised less (0% vs 23%). Conclusion: Radiation therapists' confidence and use of alternative tools to improve patient understanding improved after attending training. Implications for practice: Ongoing encouragement using alternate communication methods are recommended to assist with strengthening patient outcomes.

Introduction: Health literacy (HL) is a universal issue in healthcare. While difficult to assess an individual's HL status, the onus is on the health provider to empower patients to seek understanding of health information provided to them. Universal HL training techniques include implementing plain language and the teach-back method. The research aims to explore the perceptions of Australian radiation therapists (RTTs) learning and implementation of these tools with patients. Methods: RTTs attended two communication and HL workshops one week apart. Participants completed three anonymous surveys (before the first workshop, immediately after the second and three months post workshops) and a workshop evaluation was administered after the second workshop. Participants had the opportunity to provide written comments on all surveys and the evaluation form. A thematic analysis was performed on the written comments by two independent researchers. Results: Five themes were revealed after the thematic analysis of the surveys. These themes were: improved patient understanding, impact on professional credibility, practice and timing of using methods, appearing to be condescending to educated patients and increased patient anxiety. The workshop evaluation assessment indicated the success of and improvement for future workshops and revealed seven themes. These were: learning from others, providing a safe environment to share experiences, to be open to learning new methods, more time for learning, role-play aversion, group sizing and thinking beyond the workshops. Conclusion: While strong evidence of using HL tools for improved patient understanding exists, this qualitative review revealed unexpected barriers with implementing both the plain language and teach-back method. Implications for practice: Barriers revealed during HL training could have patient flow on effects when checking for understanding. These challenges need further exploration, to inform all health professionals.

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.

Background Practice education is a compulsory component of health programs with practice educators playing a critical role in the education of students. Practice educator characteristics may positively or negatively affect student learning in practice settings. This study aimed to identify characteristics of the ideal practice educator that lead to successful practical experiences as perceived by current practice educators working in the Australian context of diagnostic radiography, nuclear medicine, nutrition and dietetics, occupational therapy, physiotherapy and radiation therapy. Methods All practice educators (n = 1063) on the University of Newcastle Practice Educator Database were invited to participate in this prospective, cross-sectional, descriptive study via online link or paper format. Results There was a 52% response rate. The five most valued characteristics were feedback skills, non-judgemental, professionalism, clarity and listening skills. The five least valued characteristics were scholarly activity, respect for students' autonomy, well-prepared, availability and being a role model. Comparisons between disciplines, genders, ages, years in practice and levels of supervisory experience indicated some statistically significant differences, though actual differences were small. Discussion Overall there was a high degree of agreement within and between disciplines on the characteristics of the ideal practice educator. The top five skills could be classed as generic skills and not specific clinical and practice skills, thus formal training and certification schemes may enhance practice educator competence.

Background Practice education is a core component of undergraduate health programs, with the characteristics of the practice educator reported to have an influence on student experience during practical. This study analyses Australian student perceptions from six allied health professional undergraduate programs, to identify the characteristics of the ideal practice educator leading to successful placement experiences. Methods An existing survey developed for medical students was modified to incorporate both quantitative and qualitative responses. Participants included all students enrolled in six undergraduate health professions in the School of Health Sciences at the University of Newcastle, Australia (n = 1485). Students were invited to complete the survey via hard copy or online. Results There was a 54% response rate. The most valued characteristics were non-judgemental, clarity and feedback. The three least valued characteristics were scholarly activity, role model and practices evidence base practice. Students identified the importance of their relationship (respectful, inspirational and supportive) with the practice educator as being fundamental to a productive placement. Conclusion The characteristics identified by respondents were common to all six professions, with little differences between gender, year of program or number of placements completed. This study suggests that the attitude of the practice educator towards the student is one of the key factors that underpin the success of practice experience across allied health professions.

Objective: To examine current knowledge and the level of compliance of radiation safety principles in equine veterinary clinics within Australia. Method: Surveys were sent to equine veterinary surgeons working in Australia. The survey was delivered both online and in hardcopy format; it comprised 49 questions, 15 of these directly related to radiation safety. The participants were asked about their current and previous use of radiation-producing equipment. Information regarding their level of knowledge and application of radiation safety principles and practice standards was collected and analysed. Results: The use of radiation-producing equipment was evident in 94% of responding clinics (a combination of X-ray, CT and/or Nuclear Medicine Cameras). Of those with radiation-producing equipment, 94% indicated that they hold a radiation licence, 78% had never completed a certified radiation safety course and 19% of participants did not use a personal radiation monitor. In 14% of cases, radiation safety manuals or protocols were not available within clinics. Conclusions: The study has shown that knowledge and application of guidelines as provided by the Code of Practice for Radiation Protection in Veterinary Medicine (2009) is poorly adhered to. The importance of compliance with regulatory requirements is pivotal in minimising occupational exposure to ionising radiation in veterinary medicine, thus there is a need for increased education and training in the area.

This review examines the most commonly reported treatment options for ocular squamous cell carcinoma (OSCC) and periocular squamous cell carcinoma (POSCC) in horses and proposes to conclude on the most viable method based on available published studies in terms of treatment outcome, known side effects, advantages, disadvantages, and reliability of available evidence. After a literature search for peer-reviewed published articles, seven most commonly reported on treatments for OSCC and/or POSCC were identified: surgery, photodynamic therapy, carbon dioxide (CO 2 ) laser ablation, radiofrequency hyperthermia, cryotherapy, chemotherapy, and radiation therapy. Combination therapies were supported as a most successful recommendation; however, when considering site-specific outcomes, the following conclusions may be drawn: limbal squamous cell carcinoma (SCC) was most effectively treated with surgery and adjunctive therapy including CO 2 laser ablation, mitomycin C, and brachytherapy; third eyelid SCC reported good outcomes when treated with surgery alone (clear margins) and in combination with brachytherapy for unclear margins; eyelid SCC, surgical resection was usually limited and most reports supported the use of adjunctive brachytherapy, although photodynamic therapy appeared to be a promising new treatment. It was deemed unreasonable to conclude on the best treatment for cornea, conjunctivae (palpebral and bulbar), and medial canthi in isolation because of lack of evidence. A consistently favored treatment for OSCC and/or POSCC in horses does not currently exist. The presentation of data in the literature and its lack of consistency make it impossible to statistically analyze and make comparative conclusions on treatment outcomes. This review provides a basis for further research to establish a best-practice protocol. © 2014 Elsevier Inc. All rights reserved.
