Abstract

Introduction: Clinical diagnosis is a pivotal and highly valued skill in medical practice. Most current interventions for teaching and improving diagnostic reasoning are based on the dual process model of cognition. Recent studies which have applied the popular dual process model to improve diagnostic performance by “Cognitive De-biasing” in clinicians have yielded disappointing results. Thus, it may be appropriate to also consider alternative models of cognitive processing in the teaching and practice of clinical reasoning.

Methods: This is critical-narrative review of the predictive brain model.

Results: The theory of predictive brains is a general, unified and integrated model of cognitive processing based on recent advances in the neurosciences. The predictive brain is characterised as an adaptive, generative, energy-frugal, context-sensitive action-orientated, probabilistic, predictive engine. It responds only to predictive errors and learns by iterative predictive error management, processing and hierarchical neural coding. 

Conclusion: The default cognitive mode of predictive processing may account for the failure of de-biasing since it is not thermodynamically frugal and thus, may not be sustainable in routine practice. Exploiting predictive brains by employing language to optimise metacognition may be a way forward.

Abstract

Introduction: Gamification has been shown to improve academic gains, but the mechanism remains elusive. We aim to understand how psychological constructs interact, and influence medical education using mathematical modelling.

Methods: Studying a group of medical students (n=100; average age: 20) over a period of 4 years with the Personal Responsibility Orientation to Self-Direction in Learning Scale (PRO-SDLS) survey. Statistical tests (Paired t-test) and models (logistic regression) were used to decipher the changes within these psychometric constructs (Motivation, Control, Self-efficacy & Initiative), with gamification as a tool. Students were encouraged to partake in a maze (10 stations) that challenged them to answer anatomical questions using potted human specimens.

Results: We found that the combinatorial effects of the maze and Script Concordance Test (SCT) resulted in a significant improvement for “Self-Efficacy” and “Initiative” (p<0.05). However, the “Motivation” construct was not improved significantly with the maze alone (p<0.05). Interestingly, the “Control” construct was eroded in students not exposed to gamification (p<0.05). All these findings were supported by key qualitative comments such as “helpful”, “fun” and “knowledge gap” by the participants (self-awareness of their thought processes). Students found gamification reinvigorating and useful in their learning of clinical anatomy.

Conclusion: Gamification could influence some psychometric constructs for medical education, and by extension, the metacognition of the students. This was supported by the improvements shown in the SCT results. It is therefore proposed that gamification be further promoted in medical education. In fact, its usage should be more universal in education.

Abstract

Introduction: Standardised patients (SPs) have been involved in medical education for the past 50 years. Their role has evolved from assisting in history-taking and communication skills to portraying abnormal physical signs and hybrid simulations. This increases exposure of their physical and psychological domains to the learner. Asian SPs who come from more conservative cultures may be inhibited in some respect. This study aims to explore the attitudes and perspectives of Asian SPs with respect to their role and case portrayal.

Methods: This was a cohort questionnaire study of SPs involved in a high-stakes assessment activity at a university medical school in Singapore.

Results: 66 out of 71 SPs responded. Racial distribution was similar to population norms in Singapore (67% Chinese, 21% Malay, 8% Indian). SPs were very keen to provide feedback to students. A significant number were uncomfortable with portraying mental disorders (26%) or terminal illness (16%) and discussing Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS, 14%) or Sexually Transmitted Diseases (STDs, 14%). SPs were uncomfortable with intimate examinations involving the front of the chest (46%, excluding breast), and even abdominal examination (35%). SPs perceive that they improve quality of teaching and are cost effective.

Conclusion: The Asian SPs in our institution see themselves as a valuable tool in medical education. Sensitivity to the cultural background of SPs in case writing and the training process is necessary to ensure that SPs are comfortable with their role. Additional training and graded exposure may be necessary for challenging scenarios and physical examination.

Abstract

Introduction: The demanding nature of medical and health sciences studies can cause stress among students in these disciplines affecting their wellbeing and academic performance. The Perceived Stress Scale (PSS-10) is a widely used measure of perceived stress among medical students and healthcare professionals that has not yet been validated among medical and health sciences students in Hong Kong. The aim of this study is to establish the construct validity and reliability of the PSS-10 in this context.

Methods: 267 final year medical and health sciences students were surveyed using the PSS-10. The data were analysed using exploratory factor analysis for construct validity and Cronbach’s alpha coefficient and corrected item-total correlations for reliability.

Results: Exploratory factor analysis revealed a two-factor structure for PSS-10, with Cronbach’s alpha of 0.865 and 0.796, indicating good internal consistency. Corrected item-total correlations showed satisfactory correlation ranged from 0.539 to 0.748 for all items and their respective subscale. Both tests supported PSS-10 as a two-factor scale.

Conclusion: The PSS-10 is a valid measure for assessing perceived stress in Hong Kong medical and health sciences students.

Abstract

Introduction: Although, several factors have been identified as significant determinants in online learning, the human interactions with those factors and their effect on academic achievement are not fully elucidated. This study aims to determine the effect of self-regulated learning (SRL) on achievement in online learning through exploring the relations and interaction of the conception of learning, online discussion, and the e-learning experience.

Methods: A non-probability convenience sample of 128 learners in the Health Professions Education program through online learning filled-out three self-reported questionnaires to assess SRL strategies, the conception of learning, the quality of e-Learning experience and online discussion. A scoring rubric was used to assess the online discussion contributions. A path analysis model was developed to examine the effect of self-regulated learning on achievement in online learning through exploring the relations and interaction among the other factors.

Results: Path analysis showed that SRL has a statistically significant relationship with the quality of e-learning experience, and the conception of learning. On the other hand, there was no correlation with academic achievement and online discussion. However, academic achievement did show a correlation with online discussion.

Conclusion: The study showed a dynamic interaction between the students’ beliefs and the surrounding environment that can significantly and directly affect their behaviour in online learning. Moreover, online discussion is an essential activity in online learning.

Abstract

Introduction: Objective Structured Clinical Examination (OSCE) examiners come from various backgrounds. This background variability may affect the way they score examinees. This study aimed to understand the effect of background variability influencing the examiners’ score agreement in OSCE’s procedural skill.

Methods: A mixed-methods study was conducted with explanatory sequential design. OSCE examiners (n=64) in the Faculty of Medicine Universitas Kristen Duta Wacana (FoM-UKDW) took part to assess two videos of Cardio-Pulmonary Resuscitation (CPR) competence to get their level of agreement by using Fleiss Kappa. One video portrayed CPR according to performance guideline, and the other portrayed CPR not according to performance guidelines. Primary survey, CPR procedure, and professional behaviour were assessed. To confirm the assessment results qualitatively, in-depth interviews were also conducted.

Results: Fifty-one examiners (79.7%) completed the assessment forms. From 18 background categories, there was a good agreement (>60%) in: Primary survey (4 groups), CPR procedure (15 groups), and professional behaviour (7 groups). In-depth interviews revealed several personal factors involved in scoring decisions: 1) Examiners use different references in assessing the skills; 2) Examiners use different ways in weighting competence; 3) The first impression might affect the examiners’ decision; and 4) Clinical practice experience drives examiners to establish a personal standard.

Conclusion: This study identifies several factors of examiner background that allow better agreement of procedural section (CPR procedure) with specific assessment guidelines. We should address personal factors affecting scoring decisions found in this study in preparing faculty members as OSCE examiners.

Abstract

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has brought about additional challenges beyond the usual transitional stresses faced by a newly qualified doctor. We aimed to evaluate the impact of COVID-19 on interns’ stress, burnout, emotions, and implications on their training, while exploring their coping mechanisms and resilience levels.

Methods: Newly graduated doctors interning in a Paediatric department in Singapore, who experienced escalation of the pandemic from January to April 2020, were invited to participate. Participants completed the Perceived Stress Scale (PSS), Maslach’s Burnout Inventory (MBI), and Connor Davidson Resilience Scale 25-item (CD-RISC 25) pre-pandemic and 4 months into COVID-19. Group interviews were conducted to supplement the quantitative responses to achieve study aims.

Results: Response rate was 100% (n=10) for post-exposure questionnaires and group interviews. Despite working through the pandemic, interns’ stress levels were not increased, burnout remained low, while resilience remained high. Four themes emerged from the group interviews – the impacts of the pandemic on their psychology, duties, training, as well as protective mechanisms. Their responses, particularly the institutional mechanisms and individual coping strategies, enabled us to understand their unexpected low burnout and high resilience despite the pandemic.

Conclusion: This study demonstrated that it is possible to mitigate stress, burnout and preserve resilience of vulnerable healthcare workers such as interns amidst a pandemic. The study also validated a multifaceted approach that targets institutional, faculty as well as individual levels, can ensure the continued wellbeing of healthcare workers even in challenging times.

Abstract

Introduction: A novel initiative allowed third year medical students to pursue experiential learning during a year-long Enrichment Year programme as part of the core curriculum. ‘connect*ed’, an online virtual community of learning was developed to provide learning and social support to students and to help them link their diverse experiences with the common goal of being a doctor. This study examined the nature, pattern, and content of online interactions among medical students within this community of learning to identify features that support learning and personal growth.

Methods: This was a quantitative-qualitative study using platform data analytics, social network analysis, thematic content analysis to analyse the nature and pattern of online interactions. Focus group interviews with the faculty mentors and medical students were used to triangulate the results.

Results: Students favoured online interactions focused on sharing and learning from each other rather than structured tasks. Multimedia content, especially images, attracted more attention and stimulated more constructive discussion. We identified five patterns of interaction. The degree centrality and reciprocity did not affect the team interactivity but mutual encouragement by team members and mentors can promote a positive team dynamic.

Conclusion: Online interactions that are less structured, relate to personal interests, and use of multimedia appear to generate the most meaningful content and teams do not necessarily need to have a leader to be effective. A structured online network that adopts these features can better support learners who are geographically separated and engaged in different learning experiences.

Abstract

Introduction: Students in the early years of medical school should learn clinical site risk assessment skills. However, the effect of this training on clinically inexperienced students is not clear, and it is difficult for students to predict risks from a wide range of perspectives. This study aims to develop and implement three patterns of safety walk rounds (SWR) in a class of students with no clinical experience.

Methods: Three types of SWR were conducted: (A) 37 students observed a familiar classroom and predicted safety risks; (B) 39 students created a profile of a fictitious student in advance and then used Type A parameters; (C) 100 students participated. First, Type A was conducted as a practice. Next, students observed a hospital and predicted risks. All participants in Types A to C had no clinical experience. We classified all risks into perception, comprehension, and action.

Results: For each safety walk-round, there were two types of risk prediction. In Type A, risks such as perception and comprehension were more than 80%. In Types B and C, action risks were 60%. Students had little experience in observing facilities and none at finding safety risks.

Conclusion: Each method had a different risk prediction tendency. Combining the methods could enable students to acquire comprehensive skills in assessing hidden environmental patient safety risks.

I. INTRODUCTION

Freshmen orientation programmes are important milestones of university life. In Dentistry, orientation helps build camaraderie and friendship among the small undergraduate student enrolment. Before the COVID-19 pandemic, freshmen orientation featured overnight camps, mass games and group activities which involved face-to-face interactions. With the pandemic, precautionary measures were put in place to curb the spread of the virus. A key measure was the radical move away from face-to-face activities. This had a profound impact on the conduct of the orientation programme in Dentistry. The authors share their experiences as student organisers of a first-ever online freshmen orientation programme (involving 72 freshmen and 60 seniors), and highlight key lessons gleaned from the experience.

I. INTRODUCTION

Dental practitioners often encounter situations that require customising the prosthesis to satisfy the needs of patients. Artificial devices called dental appliances or prosthesis is custom fabricated for the functional, aesthetic, and psychological wellbeing of patients (Chu et al. 2013). The patient’s complaints may vary from missing natural teeth to extensive maxillofacial defects, and there is no single best rehabilitative therapy for these conditions. Designing our product is the choice, and this demands adaptive expertise, i.e., the ability to generate potential solutions (Mylopoulos et al. 2018). Maxillofacial Prosthodontics applies a variety of learning methods like systematic simulation laboratory exercises, See One, Do One, Teach One (SODOTO method), and supervised clinical practice to train the routine technical skills and clinical practice. To maximise the outcomes in the complex prosthetic treatment, the course specialists designed an “Interdisciplinary Device Development program (IDDP)”—a value-added course for the postgraduates in collaboration with the Biomedical Instrumentation Engineering Faculty of our Institution. IDDP is the first of its kind challenge-based learning model in Dentistry that uses innovations to deal with rehabilitation care beyond routine practice. This paper aims to present our IDDP model and programme outcomes.

The mal-distributed Australian medical workforce continues to result in rural medical workforce shortages. In an attempt to increase rural medical workforce, the Australian Government has invested in the Rural Health Multidisciplinary Training (RHMT) program, involving 21 medical schools (RHMT program, 2020). This funding requires participating universities to ensure at least 25% of domestic students attend a year-long rural placement during their clinical years and 50% of domestic students experience a short-term rural clinical placement for at least four weeks.

Multiple factors influence selecting a rural medical career pathway. Four basic truths presented by Talley (1990) USA on successful medical career pathways are still pertinent today.
