Abstract: The ScienceReady preparatory course is an intensive study designed to improve beginning university undergraduate students’ understanding of medical/scientific concepts, and reduce their anxiety about studying the science component of their enrolled programs. Its goals are to stimulate students’ science curiosity and provide the fundamental scientific content they are expected to know and build further on the knowledge that will feature in their upcoming programs. This article aims to describe the ScienceReady course, discuss the impact of the course on the participants, determine the relationship of the course with self-efficacy, and explain the implications of the results. Students were tested before and after the course to ascertain whether it increased or decreased or not affected self-efficacy. The results of the pre- and post-test surveys were unequivocal. The majority of the in idual items for the self-efficacy questionnaire showed a significant increase in self-efficacy post-course.

Abstract: Simulation‐based education is a significant aspect of teaching clinical skills in tertiary medical radiation science programmes, allowing students to experience the clinical setting in a safe environment. As an educational tool, simulation exists in many valid forms including role play, interprofessional simulation and virtual reality simulation. This scoping review looks at the current literature in this field to identify the evidence surrounding simulation‐based education for medical radiation students. The purpose of this review is to provide an evidence‐based guide for educators, identify gaps in the literature and suggest areas of future research. Data extraction was performed on 33 articles where the interventions could be categorised into either role play simulation, virtual simulation, simulation videos or online learning environments. Most studies demonstrated that simulation could improve clinical competence and increase preparedness and confidence for clinical placement. Student satisfaction remained high throughout the studies however, it is the view of many that although simulation‐based education is a valid and effective tool, it is complementary to and not a replacement for clinical placement.

Abstract: Purpose: Cultural competence in healthcare assists in the delivery of culturally sensitive and high-quality services. This scoping review aims to provide an overview of the available evidence and to examine the effectiveness of classroom-based intervention strategies used to enhance the cultural competence of undergraduate health science students.Methods: A comprehensive and systematic literature search was undertaken in databases, including Cochrane Library, Medline, and Emcare. Articles were eligible if they employed an experimental study design to assess classroom-based cultural competency education for university students across the health science disciplines. Two reviewers independently screened and extracted relevant data pertaining to study and participant characteristics using a charting table. The outcomes included knowledge, attitudes, skills, and perceived benefits.Results: Ten studies were analysed. Diverse approaches to cultural education exist in terms of the mode, frequency, and duration of interventions. For the knowledge outcome, students who experienced cultural education interventions yielded higher post-test scores than their baseline cultural knowledge, but without a significant difference from the scores of students who did not receive interventions. Data relating to the skills domain demonstrated positive effects for students after experiencing interventions. Overall, students were satisfied with their experiences and demonstrated improvements in confidence and attitudes towards culturally competent practice.Conclusion: Across health science disciplines, cultural competency interventions were shown to be effective in enhancing knowledge acquisition, performance of skills, attitudes, and student satisfaction. Future research is necessary to address the significant absence of control arms in the current literature, and to assess long-term effects and patient-related outcomes.

Abstract: Simulation-based learning is a crucial educational tool for disciplines involving work-integrated learning and clinical practice. Though its uptake is becoming increasingly common in a range of fields, this uptake is less profound in diagnostic radiography and computed tomography. This study explored whether CT simulator software may be a viable option to facilitate the development of practical clinical skills in an effective, safe and supported environment. A cross-sectional mixed methods design was employed. Students in their third year of study undertook formal simulation CT learning using the Siemens SmartSimulator, prior to a six-week off-c us clinical experience. A pre- (n = 42, response rate = 39%) and post-clinical placement Likert scale survey was completed (n = 21, retention rate = 50%), as well as focus group interviews to gather qualitative data (n = 21). Thematic analysis was employed to explore how the simulator developed students’ knowledge of CT concepts and preparedness for clinical placement. Survey scores were high, particularly in terms of satisfaction and relevancy. Focus groups drew attention to the software’s capacity to build on foundational principles, prepare students for placement and closely emulate the clinical environment. Students highlighted the need for continual guidance and clinical relevance and maintained that interactive simulation was inferior to real-world clinical placement. The integration of CT simulator software has the potential to increase knowledge, confidence, and student preparation for the clinical environment.

Abstract: Ankle traumas are common presenting injuries to emergency departments in Australia and worldwide. The Ottawa Ankle Rules (OAR) are a clinical decision tool to exclude ankle fractures, thereby precluding the need for radiographic imaging in patients with acute ankle injury. Previous studies support the OAR as an accurate means of excluding ankle and midfoot fractures, but have included a paediatric population, report both the ankle and mid-foot, or are greater than 5 years old. This systematic review and meta-analysis aimed to update and assess the existing evidence of the diagnostic accuracy of the Ottawa Ankle Rule (OAR) acute ankle injuries in adults. A systematic search and screen of was performed for relevant articles dated 1992 to 2020. Prospective and retrospective studies documenting OAR outcomes by physicians to assess ankle injuries were included. Critical appraisal of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) tool. Outcomes related to psychometric data were pooled using random effects or fixed effects modelling to calculate diagnostic performance of the OAR. Between-study heterogeneity was assessed using the Higgins I2 test, with Spearman’s correlation test for threshold effect. From 254 unique studies identified in the screening process, 15 were included, involving 8560 patients from 13 countries. Sensitivity, specificity, negative likelihood ratio, positive likelihood ratio and diagnostic odds ratio were 0.91 (95% CI, 0.89 to 0.92), 0.25 (95% CI, 0.24 to 0.26), 1.47 (95% CI, 1.11 to 1.93), 0.15 (95% CI, 0.72 to 0.29) and 10.95 (95% CI, 5.14 to 23.35) respectively, with high between-study heterogeneity observed (sensitivity: I2 = 94.3%, p 0.01 specificity: I2 = 99.2%, p 0.01). Most studies presented with low risk of bias and concern regarding applicability following assessment against QUADAS-2 criteria. Application of the OAR is highly sensitive and can correctly predict the likelihood of ankle fractures when present, however, lower specificity rates increase the likelihood of false positives. Overall, the use of the OAR tool is supported as a cost-effective method of reducing unnecessary radiographic referral, that should improve efficiency, lower medical costs and reduce waiting times.

Abstract: Advancement within the Medical Radiation Profession has seen an increased need for Medical Radiation Practitioners (MRPs) to develop research skills to provide and access relevant and accurate information to maintain best practice. The aim of this study was to ascertain the current research demographics of Australian Medical Radiation Practitioners (MRPs), determine perceived barriers to participating in research and to establish needs-based initiatives to support MRPs in undertaking research. A quantitative and qualitative cross-sectional survey of Australian MRPs using an electronic survey tool was distributed between November and December 2020. Participants were recruited via an invitation email sent to Australian Society of Medical Imaging and Radiation Therapy (ASMIRT) members. A chain-referral s ling technique was adopted for data collection. A total of 431 participants responded to the survey, representing 2.3% of Australian MRPs. The majority of respondents had a bachelor's degree or higher (71.9%) with 8.4% having postgraduate research qualifications (PhD- 3.2% Professional Doctorate- 0.7% Masters- 4.5%). Of the respondents, 15.4% plan to undertake postgraduate research in the future, with 68.2% having no plans for postgraduate research. Respondents identified lack of time (47.0%), lack of interest (33.4%), cost (24.2%) and workplace support (23.9%) as contributing factors for not undertaking postgraduate research. The number of MRPs who have been awarded or will be awarded a postgraduate degree has increased over recent decades. However, many still indicate a lack of interest in being actively involved in research. Targeted support mechanisms should be implemented to address perceived or real barriers to continue to grow research capacity within the profession.

Abstract: The goal of this programmatic paper is to highlight a close connection between the core problem in the philosophy of medicine, i.e. the concept of health, and the core problem of the philosophy of mind, i.e. the concept of consciousness. I show when we look at these phenomena together, taking the evolutionary perspective of modern state-based behavioural and life-history theory used as the teleonomic tool to Darwinize the agent- and subject-side of organisms, we will be in a better position to make sense of them both as natural phenomena.

Abstract: This systematic review and meta-analysis aimed to evaluate the current literature on diagnostic test accuracy (DTA) of imaging modalities for adults with acute pulmonary embolism (APE). Medical imaging plays an integral role in evaluating and managing those with APE. Guidance for imaging modality use for APE diagnosis varies due to a lack of clinical standardisation. Despite this, CTPA remains the first-line imaging modality used by clinicians. A literature search of PubMed, EMBASE, Trove and Mednar databases (2012-2020 English language) was performed. Studies assessing the DTA of imaging modalities for APE diagnosis were included. DTA studies methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2 tool). Results of eligible studies were pooled using random or fixed effects modelling the calculate the pooled DTA of explored imaging modalities for APE. The Higgins I 10 Studies, involving 998 participants, were enrolled and pooled using the random effects model. Of the explored modalities, magnetic resonance imaging (MRI), specifically pulmonary MRI and magnetic resonance pulmonary angiography (MRPA) exhibited the highest pooled DTA. Sensitivity, specificity, negative likelihood ratio, positive likelihood ratio and diagnostic odds ratio for MRPA were 0.952 (95% CI, 0.881 to 0.987), 0.857 (95% CI, 0.637 to 0.97), 5.631 (95% CI, 2.163 to 14.659), 0.06 (95% CI, 0.007 to 0.537) and 80.310 (95% CI, 15.607 to 413.25) respectively. Based on the QUADAS-2 criteria, most studies presented low to moderate risk of bias and concern regarding applicability. The explored ultrasound and MRI protocols which exhibit a lower radiation burden when compared to the current gold standard computed tomography pulmonary angiography (CTPA), have acceptable diagnostic accuracy for APE and can be useful in certain situations.

Abstract: The sonographic appearance of the substantia nigra is abnormally bright and enlarged (hyperechogenic) in young adults with a history of illicit stimulant use. The abnormality is a risk factor for Parkinson's disease. The aim of the current study was to identify the type of illicit stimulant drug associated with substantia nigra hyperechogenicity and to determine if in iduals with a history of illicit stimulant use exhibit clinical signs of parkinsonism. We hypothesised that use of hetamines (primarily meth hetamine) is associated with substantia nigra hyperechogenicity and clinical signs of parkinsonism. The area of echogenic signal in the substantia nigra was measured in abstinent human hetamine users (n = 27 33 ± 8 years) and in three control groups comprising a) 'ecstasy' users (n = 19 23 ± 3 years), b) cannabis users (n = 30 26 ± 8 years), and c) non-drug users (n = 37 25 ± 7 years). A subset of subjects (n = 55) also underwent a neurological examination comprising the third and fifth part of the Unified Parkinson's Disease Rating Scale. Area of substantia nigra echogenicity was significantly larger in the hetamine group (0.276 ± 0.080 cm(2)) than in the control groups (0.200 ± 0.075, 0.190 ± 0.049, 0.191 ± 0.055 cm(2), respectively P < 0.002). The score on the clinical rating scale was also significantly higher in the hetamine group (8.4 ± 8.1) than in pooled controls (3.3 ± 2.8 P = 0.002). Illicit use of hetamines is associated with abnormal substantia nigra morphology and subtle clinical signs of parkinsonism. The results support epidemiological findings linking use of hetamines, particularly meth hetamine, with increased risk of developing Parkinson's disease later in life.

Abstract: This pilot study aimed to evaluate the knowledge and practices of South Australian radiographers regarding lateral elbow repositioning and to determine whether an educational poster could improve repositioning knowledge. The study was undertaken in four stages. Stage one involved the development of a survey to explore radiographer knowledge and practices surrounding lateral elbow repositioning. Stage two involved the development of an educational poster. Stage three was a pilot validity study. Three participants (n = 3) were involved in testing the validity and test-retest reliability of the survey and the poster. Stage four was the interventional study which involved the distribution of surveys to two radiography departments in South Australia on two occasions, before and after the distribution of the poster. Six complete data sets were analysed. The pilot validity study ensured the test-retest reliability of the survey was strong (P = .629). It was determined that an educational poster made no significant difference to the knowledge of lateral elbow radiograph repositioning among radiographers (P = .253). It was indicated that this result was not due to familiarity with the presurvey questions (P = .171). Thematic analysis of the open discussion questions found that most participants found the poster helpful but did not consider repositioning to be difficult. The introduction of the poster did not increase image repeat rate and the poster was used moderately over the study length. As this study was unable to determine whether a poster could improve the knowledge and practices of lateral elbow repositioning among radiographers, further research is needed.

Abstract: Variability and inaccuracies in the diagnosis of prostate cancer, and the risk of complications from invasive tests, have been extensively reported in the research literature. To address this, the use of artificial intelligence (AI) has been attracting increased interest in recent years to improve the diagnostic accuracy and objectivity. Although AI literature has reported promising results, further research is needed on the identification of evidence gaps that limit the potential adoption in prostate cancer screening practice. A systematic electronic search strategy will be used to identify peer-reviewed articles published from inception to the date of searches and indexed in CINAHL, IEEE Xplore, MEDLINE, Scopus, and Web of Science Core Collection databases. Registries including Cochrane Central Register of Controlled Trials, ClinicalTrials.gov and International Clinical Trials Registry Platform (ICTRP) will be searched for unpublished studies, and experts were invited to provide suitable references. The research and reporting will be based on Cochrane recommendations and PRISMA guidelines, respectively. The screening and quality assessment of the articles will be conducted by two of the authors independently, and conflicts will be resolved by a third author. This systematic review will summarise the use of AI techniques to predict the need for prostate biopsy based on clinical and demographic indicators, including its diagnostic accuracy and readiness for adoption in clinical practice.

Abstract: To assess the adequacy of clinical information with reference to the Ottawa Ankle Rules (OAR) in X-ray referrals for adults with traumatic ankle injury in the ED of a South Australian tertiary hospital and report upon referring trends between emergency department clinicians. A retrospective clinical audit of adult ankle X-ray referrals in the emergency department was conducted. Eligible referrals were screened for their adherence to the OAR, patient details, clinical history and referrer. A logistic regression was used to determine the influence of these factors on the likelihood of being referred for X-rays despite not meeting the OAR criteria. Sensitivity, specificity, positive and negative likelihood ratios and their associated confidence intervals were calculated to assess the diagnostic accuracy of the OAR for those referred. Out of the 262 eligible referrals, 163 were deemed to have met the criteria for the OAR. Physiotherapists showed the highest OAR compliance of 77.3% and were the most accurate in their use of the rules, with a sensitivity of 0.86. Medical officers, registrars and interns were 2.5 times more likely to still refer a patient for X-ray if they did not meet the OAR criteria, compared to physiotherapists as the baseline. Patient age, duration of injury etc. were not significantly associated with likelihood of referral (even when they did not meet OAR criteria). The overall sensitivity, specificity, positive and negative likelihood ratios of the OAR were 0.59 (95% CI [0.47–0.71]), 0.37 (95% CI [0.30–0.44]), 0.93 (95% CI [0.76–1.16]) and 1.10 (95% CI [0.82–1.48]) respectively. The results of this audit demonstrated poor sensitivity and moderate compliance by referrers with the rule. Reasonable evidence exists for the implementation of in idual and/or institutional-based change strategies to improve clinician compliance and accuracy with use of the OAR.

Abstract: Diagnostic reference levels (DRLs) identify unusually high patient radiation exposures and are required for dose optimisation. DRLs for pediatric fluoroscopic examinations are not widely determined in Australia. Our objectives were to establish DRLs for pediatric fluoroscopic examinations in a South Australian tertiary hospital and compare these to previously published data and to explore relationships between patient dose area product (DAP), age and fluoroscopy times. Dose data from 365 pediatric patients undergoing 5 fluoroscopic examinations were retrospectively collected for a 3-year period commencing January 2018 to develop local DRLs. Relationships between DAP, age and fluoroscopy time were explored using scatterplots, Spearman's correlation, and regression analyses. Local DRLs were significantly lower than data published previously, possibly reflecting technological and procedural advancements. Each 1-year increase in patient age was associated with a 0.77 μGy·m This study provides updated Australian pediatric fluoroscopic DRLs, with the intention of promoting a national database for benchmarking pediatric doses. The local DRLs can be used for dose comparisons and optimisation between facilities.
