Taking the Pressure Off the Patient - Understanding Digital Rectal Examinations on a Real Subject.
Better understanding of palpation techniques during unsighted physical examinations has mostly been limited to qualitative and quantitative studies of performance of experts whilst conducting examinations on plastic benchtop models. However, little is known about their performance when conducting such examinations on real subjects. OBJECTIVE: The aim of this paper is to better understand palpation techniques of experts whilst conducting a Digital Rectal Examination on a real subject. METHODS: We recruited four consultants from relevant specialties and asked them to conduct two DREs on a Rectal Teaching Assistant whilst wearing small position and pressure sensors on their examining finger. We segmented the relevant anatomy from an MRI taken of the pelvic region, registered 3D models and analysed retrospectively performance in relation to executed tasks, supination/pronation, palpation convex hull and pressure applied. RESULTS: Primary care consultants examined the anatomy more holistically compared to secondary care experts, the maximum pressure applied across experiments is 3.3N, overall the pressure applied on the prostate is higher than that applied to rectal walls, and the urologist participant not only applied the highest pressure but also did so with the highest most prominent frequency (15.4 and 25.3 Hz). CONCLUSIONS: The results of our research allow for better understanding of experts' technical performance from relevant specialities when conducting a DRE, and suggest the range of pressure applied whilst palpating anatomy. SIGNIFICANCE: This research will be valuable in improving the design of haptics-based learning tools, as well as in encouraging reflection on palpation styles across different specialities to develop metrics of performance

Twelve tips for designing and implementing an academic coaching program
Coaching has become increasingly popular as a mechanism to support learning across the health professions education (HPE) continuum. While there is a growing body of literature in this area, there is minimal guidance related to the design and implementation of academic coaching in health professional courses. This paper seeks to contribute to this literature by presenting guidance for academic developers who are considering introducing academic coaching into a health professional course. The 12 tips are based on the authors’ collective experiences of designing and implementing academic coaching in university medical courses in Australia and the UK. Although focused on medical education, this paper is intended to have applicability across the health professions, and potentially across university and postgraduate training contexts. Together, the tips offer a strategic and operational framework to guide the design and implementation of academic coaching initiatives in health professions education.The author(s) reported there is no funding associated with the work featured in this article
Team-Based Learning Analytics: An Empirical Case Study
Many medical schools that have implemented team-based learning (TBL) have also incorporated an electronic learning architecture, commonly referred to as a learning management system (LMS), to support the instructional process. However, one LMS feature that is often overlooked is the LMS's ability to record data that can be used for further analysis. In this article, the authors present a case study illustrating how one medical school used data that are routinely collected via the school's LMS to make informed decisions. The case study started with one instructor's observation that some teams in one of the undergraduate medical education learning modules appeared to be struggling during one of the team activities; that is, some teams seemed unable to explain or justify their responses to items on the team readiness assurance test (tRAT). Following this observation, the authors conducted 4 analyses. Their analyses demonstrate how LMS-generated and recorded data can be used in a systematic manner to investigate issues in the real educational environment. The first analysis identified a team that performed significantly poorer on the tRAT. A subsequent analysis investigated whether the weaker team's poorer performance was consistent over a whole module. Findings revealed that the weaker team performed poorer on the majority of the TBL sessions. Further investigation using LMS data showed that the weaker performance was due to the lack of preparation of one individual team member (rather than a collective poor tRAT performance). Using the findings obtained from this case study, the authors hope to convey how LMS data are powerful and may form the basis of evidence-based educational decision making

Exploring the feasibility of using very short answer questions (VSAQs) in team-based learning (TBL)
Copyright © 2021 The Authors. Background: Team-based learning (TBL) currently relies on single best answer questions (SBAQs) to provide immediate feedback. Very short answer questions (VSAQs) are a reliable and discriminatory alternative that encourage learners to use more authentic clinical reasoning strategies compared to SBAQs. However, the challenge of marking VSAQs has limited their integration into TBL; we therefore explored the feasibility of VSAQs within a TBL session. Methods: An online platform was developed to allow immediate marking of VSAQs during the TBL sessions. As part of the readiness assurance process, students completed VSAQs and SBAQs, which were marked in real time. Results: Instructors were able to mark all VSAQs during the individual readiness assurance test (iRAT), which facilitated the provision of immediate feedback during the team readiness assurance test (tRAT). The mean time to mark five VSAQs was 422 seconds (SD 73 seconds). For VSAQs, the number of attempts to reach the correct answer ranged from 1 to 38, compared to 1 to 4 for SBAQs. In total, 71.6% of students agreed that using VSAQs in TBL helped to emphasise group discussions. Discussion: The wide range of attempts at, and students’ perspectives of VSAQs are suggestive of their positive impact on student discussion during TBL. We demonstrate how new technology allows VSAQs to be feasibly integrated into TBL with the potential to enrich group discussions.Nanyang Technological University's EdeX learning and teaching project grant

Development of a three-dimensional printed heart from computed tomography images of a plastinated specimen for learning anatomy
Copyright © 2020 The Author(s) and Korean Association of ANATOMISTS. Learning anatomy is commonly facilitated by use of cadavers, plastic models and more recently three-dimensional printed (3DP) anatomical models as they allow students to physically touch and hold the body segments. However, most existing models are limited to surface features of the specimen, with little opportunity to manipulate the structures. There is much interest in developing better 3DP models suitable for anatomy education. This study aims to determine the feasibility of developing a multi-material 3DP heart model, and to evaluate students' perceptions of the model. Semi-automated segmentation was performed on computed tomgoraphy plastinated heart images to develop its 3D digital heart model. Material jetting was used as part of the 3D printing process so that various colors and textures could be assigned to the individual segments of the model. Morphometric analysis was conducted to quantify the differences between the printed model and the plastinated heart. Medical students' opinions were sought using a 5-point Likert scale. The 3DP full heart was anatomically accurate, pliable and compressible to touch. The major vessels of the heart were color-coded for easy recognition. Morphometric analysis of the printed model was comparable with the plastinated heart. Students were positive about the quality of the model and the majority of them reported that the model was useful for their learning and that they would recommend their use for anatomical education. The successful feasibility study and students' positive views suggest that the development of multi-material 3DP models is promising for medical education
Student assistantship programme: an evaluation of impact on readiness to transit from medical student to junior doctor.
BACKGROUND: Studies report that medical graduates are not prepared for practice as expected, and interventions have been developed to prepare them for practice. One such intervention is the assistantship, which provides hands-on opportunities to hone clinical skills and undertake responsibilities under supervision. The Lee Kong Chian School of Medicine (LKCMed) is Singapore's newest medical school, and students undergo a Student Assistantship Programme (SAP) to prepare for practice as junior doctors (PGY1). This study evaluated the SAP from the students' and clinical supervisors' perspectives. METHODS: Students completed online questionnaires to assess readiness for practice before and after SAP, and a subsample were interviewed about their experiences of SAP and its impact on their preparedness for PGY1. In addition, after our graduates had begun work as PGY1 doctors, their clinical supervisors completed an online questionnaire and were interviewed about the perceived benefits of SAP and the attributes of our graduates as junior doctors. RESULTS: Fifty (96%) students completed the pre-SAP questionnaire and 46 (92%) completed the post-SAP questionnaire. Levels of preparedness increased post-SAP (mean scores range pre-SAP: 2.38 to 4.32 vs post-SAP: 3.08 to 4.48); so did opportunities to undertake PGY1 duties (pre-SAP: 56% vs post-SAP: 96%), and hands-on experience in medical emergencies (pre-SAP: 76% vs post-SAP: 89%).Experience of acute care situations increased except "paracetamol overdose". Readiness to be first respondents in ten acute situations improved (statistically significant for asthma, chronic obstructive pulmonary disease exacerbation, gastrointestinal bleed, sepsis, and adverse drug reactions). Three themes emerged from twenty-five student interviews: learning about the work environment, opportunities to learn in a safe environment, and enhancing SAP for future students. Thirty-three supervisors completed the questionnaire, and 70% rated SAP positively in preparing students for PGY1. Eight supervisors interviewed shared positively about the content, timing, and duration of SAP; and suggested future SAPs help students to develop coping and reflective skills. CONCLUSIONS: The SAP improved students' preparedness and experience across clinical areas, and students felt the SAP helped bridge undergraduate curriculum and work, provided opportunities to hone their skills and learn from junior doctors. Most clinical supervisors rated the SAP effective in preparing students for PGY1. This is the first formal evaluation of an assistantship in Singapore, and the findings are encouraging from the perspective of students and PGY1 supervisors
Role of social comparison in preparedness for practice as a junior doctor in Singapore: a longitudinal qualitative study
ObjectivesTo date, most research on medical graduates’ preparedness for practice has conceptualised preparedness as something possessed by the individual. However, new doctors work within social settings with other people and, given this, we argue that preparedness has a social and comparative dimension. The aim of this paper is to explore medical students’/graduates’ self-assessments of their preparedness for practice using the lens of social comparison theory.SettingWe invited medical students from one of Singapore’s three medical schools who were in their final-year Student Assistantship Programme to participate in semi-structured interviews, and follow-up interviews 6 months later when they were working as junior doctors. Data was collected from two cohorts, in 2018 and 2019. Initial analysis of interview transcripts was inductive and thematic. Social comparison theory was used for subsequent theory-driven analysis.Participants31 participants took part, of whom 21 also engaged in follow-up interviews.ResultsWe identified three uses of social comparison: as coping strategy to manage uncertainties in transitions where there was no formal, objective testing of their performance; as a means to confirm their self-perceived preparedness (upwards or downwards, eg, being better or worse prepared than comparator others); and as the basis for decision-making (eg, changing career choices).ConclusionsSenior medical students and newly-graduated doctors compare themselves with peers and near-peers in terms of prior learning and current performance to evaluate and understand their own performance at work. Future studies need to examine further how the feeling of preparedness or unpreparedness generated from social comparisons may affect subsequent clinical performance and professional development.</jats:sec
A Surprising Prevention Success: Why Did the HIV Epidemic Decline in Zimbabwe?

Training of front-line health workers for tuberculosis control: Lessons from Nigeria and Kyrgyzstan
Efficient human resources development is vital for facilitating tuberculosis control in developing countries, and appropriate training of front-line staff is an important component of this process. Africa and Central Asia are over-represented in global tuberculosis statistics. Although the African region contributes only about 11% of the world population, it accounts for at least 25% of annual TB notifications, a proportion that continues to increase due to poor case management and the adverse impact of HIV/AIDS. Central Asia's estimated current average tuberculosis prevalence rate of 240/100 000 is significantly higher than the global average of 217/100 000. With increased resources currently becoming available for countries in Africa and Central Asia to improve tuberculosis control, it is important to highlight context-specific training benchmarks, and propose how human resources deficiencies may be addressed, in part, through efficient (re)training of frontline tuberculosis workers. This article compares the quality, quantity and distribution of tuberculosis physicians, laboratory staff, community health workers and nurses in Nigeria and Kyrgyzstan, and highlights implications for (re)training tuberculosis workers in developing countries
Uganda's HIV Prevention Success: The Role of Sexual Behavior Change and the National Response
There has been considerable interest in understanding what may have led to Uganda's dramatic decline in HIV prevalence, one of the world's earliest and most compelling AIDS prevention successes. Survey and other data suggest that a decline in multi-partner sexual behavior is the behavioral change most likely associated with HIV decline. It appears that behavior change programs, particularly involving extensive promotion of “zero grazing” (faithfulness and partner reduction), largely developed by the Ugandan government and local NGOs including faith-based, women’s, people-living-with-AIDS and other community-based groups, contributed to the early declines in casual/multiple sexual partnerships and HIV incidence and, along with other factors including condom use, to the subsequent sharp decline in HIV prevalence. Yet the debate over “what happened in Uganda” continues, often involving divisive abstinence-versus-condoms rhetoric, which appears more related to the culture wars in the USA than to African social reality
