When Play Reveals the Ache: Introducing Co-constructive Patient Simulation for Narrative Practitioners in Medical Education.

Despite the ubiquity of healthcare simulation and the humanities in medical education, the two domains of learning remain unintegrated. The stories suffused within healthcare simulation have thus remained unshaped by the developments of narrative medicine and the health humanities. Healthcare simulation, in turn, has yet to utilize concepts like co-construction and narrative competence to enrich learners' understanding of patient experience alongside their clinical competencies. To create a conceptual bridge between these two fields (including narrative-based inquiry more broadly), we redescribe narrative competence via Ronald Heifetz's distinction of "technical" and "adaptive" challenges outlined in his adaptive leadership model. Heifetz, we argue, enriches learners' self-understanding of the unique demands of cultivating narrative competence, which can be both elucidated on the page and tested within the charged yet supportive simulation environment. We introduce Co-constructive Patient Simulation (CCPS) to demonstrate how working with simulated patients can support narrative work by drawing on the clinical vicissitudes of learners in the formulation and enactment of case studies. The three movements of CCPS-resensing, retelling, and retooling-told through learner experiences, describe the affinities and divergences between narrative medicine's sequence of attention, representation, and affiliation; Montello's three forms of narrative competence (departure, performance, change), and Heifetz's three steps (observe, interpret, and intervene) of adaptive leadership.

Mindfulness training in medical education as a means to improve resilience, empathy, and mental health in the medical profession.

The high rates of depression, burnout, and increased risk of suicide among medical students, residents, and physicians in comparison with other careers signal a mental health crisis within our profession. We contend that this crisis coupled with the inadequate acquisition of interpersonal skills during medical education results from the interaction between a challenging environment and the mental capital of individuals. Additionally, we posit that mindfulness-based practices are instrumental for the development of major components of mental capital, such as resilience, flexibility of mind, and learning skills, while also serving as a pathway to enhance empathy, compassion, self-awareness, conflict resolution, and relational abilities. Importantly, the evidence base supporting the effectiveness of mindfulness-based interventions has been increasing over the years, and a growing number of medical schools have already integrated mindfulness into their curricula. While we acknowledge that mindfulness is not a panacea for all educational and mental health problems in this field, we argue that there is currently an unprecedented opportunity to gather momentum, spread and study mindfulness-based programs in medical schools around the world as a way to address some longstanding shortcomings of the medical profession and the health and educational systems upon which it is rooted.

Role of knowledge and reasoning processes as predictors of resident physicians' susceptibility to anchoring bias in diagnostic reasoning: a randomised controlled experiment.

BACKGROUND: Diagnostic errors have been attributed to reasoning flaws caused by cognitive biases. While experiments have shown bias to cause errors, physicians of similar expertise differed in susceptibility to bias. Resisting bias is often said to depend on engaging analytical reasoning, disregarding the influence of knowledge. We examined the role of knowledge and reasoning mode, indicated by diagnosis time and confidence, as predictors of susceptibility to anchoring bias. Anchoring bias occurs when physicians stick to an incorrect diagnosis triggered by early salient distracting features (SDF) despite subsequent conflicting information. METHODS: Sixty-eight internal medicine residents from two Dutch university hospitals participated in a two-phase experiment. Phase 1: assessment of knowledge of discriminating features (ie, clinical findings that discriminate between lookalike diseases) for six diseases. Phase 2 (1 week later): diagnosis of six cases of these diseases. Each case had two versions differing exclusively in the presence/absence of SDF. Each participant diagnosed three cases with SDF (SDF+) and three without (SDF-). Participants were randomly allocated to case versions. Based on phase 1 assessment, participants were split into higher knowledge or lower knowledge groups. MAIN OUTCOME MEASUREMENTS: frequency of diagnoses associated with SDF; time to diagnose; and confidence in diagnosis. RESULTS: While both knowledge groups performed similarly on SDF- cases, higher knowledge physicians succumbed to anchoring bias less frequently than their lower knowledge counterparts on SDF+ cases (p=0.02). Overall, physicians spent more time (p<0.001) and had lower confidence (p=0.02) on SDF+ than SDF- cases (p<0.001). However, when diagnosing SDF+ cases, the groups did not differ in time (p=0.88) nor in confidence (p=0.96). CONCLUSIONS: Physicians apparently adopted a more analytical reasoning approach when presented with distracting features, indicated by increased time and lower confidence, trying to combat bias. Yet, extended deliberation alone did not explain the observed performance differences between knowledge groups. Success in mitigating anchoring bias was primarily predicted by knowledge of discriminating features of diagnoses.

Harnessing student feedback to transform teachers: Role of emotions and relationships.

INTRODUCTION: Feedback is crucial to promote learning and improve performance. However, we lack a nuanced understanding of how medical teachers reflect on and internalise (or not) student feedback (SF). This study aims to fill this gap by exploring how teachers make sense of SF to improve their performance and nurture their personal and professional development. METHODS: In this cross-sectional qualitative study based on a constructivist paradigm, 14 medical teachers individually drew a Rich Picture (RP) of a feedback experience in which they received informal or formal feedback from students, resulting in a personal or professional change. After the drawing, we interviewed the participants to deepen our understanding of teachers' experiences. We analysed the drawings and interview transcripts using an iterative process of thematic analysis. RESULTS: SF that culminated in personal or professional change is a highly emotional experience for teachers, often with long-lasting consequences. It may threaten or reassure their self-concept and professional identity, generating feedback avoidance or feedback-seeking behaviour. SF is particularly powerful in transforming teaching practices when teachers feel connected to students through an honest and constructive relationship. Remarkably, some teachers intentionally build relationships with certain (selected) students to get 'qualified' feedback. SF acceptance also increases when teachers are open to receiving feedback and there is an institutional culture that values feedback. Finally, medical teachers believe that formal (planned) feedback is relevant to improve the curriculum, while informal (spontaneous) feedback is important for promoting teachers' personal and professional development. DISCUSSION: SF has the potential to become a transformative learning experience for teachers. The student-teacher relationship and teachers' emotional reactions affect the way teachers make sense of and internalise SF and enact behavioural change. Understanding the complexity surrounding SF is vital for supporting teachers in seizing opportunities for growth and in nurturing a meaningful relationship with the act of teaching.

Family dyads, emotional labor, and holding environments in the simulated encounter: co-constructive patient simulation as a reflective tool in child and adolescent psychiatry training.

BACKGROUND: Patient simulation has been used in medical education to provide a safe and supportive learning environment for learners to practice clinical and interpersonal skills. However, simulation involving pediatric populations, particularly in child and adolescent psychiatry, is rare and generally does not reflect the child-caregiver dyad or the longitudinal aspects of this care, nor does it provide learners with an opportunity to engage with and reflect on these dynamics. METHODS: We organized as an educational opportunity a series of seven observed patient simulation sessions with a cohort of a dozen child and adolescent psychiatrists (eight fellows approaching graduation and four senior educators). In these sessions, we utilized the co-constructive patient simulation model to create the simulation cases. We included the use of at least two patient actors in most sessions, and two of the case narratives were longitudinally followed across multiple simulation sessions. We approached the data collected during the simulations and their respective debriefings by using thematic analysis informed by a symbolic interactionist approach. RESULTS: Based on data from the debriefing sessions and longitudinal narratives, we identified four overarching themes: (1) Reflecting on dyadic challenges: role reversal and individuation; (2) Centering the child, allying with the parent, and treating the family system; (3) Ambivalence in and about the parent-child dyad; and (4) Longitudinal narratives and ambivalence over time. CONCLUSION: The emotional experience of the simulations, for interviewers and observers alike, provided an opportunity to reflect on personal and professional experiences and triggered meaningful insights and connections between participants. These simulated cases called for emotional labor, particularly in the form of creating holding environments; in this way, the simulated encounters and the debriefing sessions became dialogic experiences, in which the patient and provider, parent and child, and learner and instructor could co-construct meaning and foster professional development as reflective practitioners.

Co-Constructive Patient Simulation as an Experiential Tool for Continuing Professional Development in Healthcare.

In this commentary, we examine how to use the recently developed educational method called Co-constructive Patient Simulation (CCPS) to improve continuous professional development in healthcare. CCPS invites learners to participate in the creation of meaningful simulated scenarios while fostering reflection-in/on/for-action and community-building. By participating in the creation of the simulated scenarios, learners guarantee that the challenges addressed by the learning activities are aligned with their developmental stages and needs. Additionally, as learners may invite supervisors to take the "hot seat" during the simulation session, the CCPS approach allows learners to witness how supervisors would handle situations perceived as challenging. This exchange of roles creates an opportunity for camaraderie, as supervisors expose themselves and assume a vulnerable position. This camaraderie facilitates educational bonding and community building. As a result, in this participatory and co-creative approach to simulation, experts become the facilitators of a learner-centred activity, which increases motivation and allows tailored and contextualised learning. This co-constructive approach to simulation adds to the repertoire of more traditional CPD strategies by fostering spontaneity and authenticity. It integrates learning opportunities in clinical practice, amplifies learner's critical reflection and autonomy, and harnesses real-life challenges to offer meaningful solutions to lifelong learning. The democratic environment optimised by experts joining the activity and sharing their vulnerabilities with trainees further catalyzes the creation of a community for teaching, learning, and shared development.

Exploring Medical Students' Learning Around Uncertainty Management Using a Digital Educational Escape Room: A Design-based Research Approach.

Introduction: Medical professionals meet many transitions during their careers, and must learn to adjust rapidly to unfamiliar workplaces and teams. This study investigated the use of a digital educational escape room (DEER) in facilitating medical students' learning around managing uncertainty in transitioning from classroom to clinical placement. Methods: We used design-based research to explore the design, build, and test of a DEER, as well as gain insight into how these novel learning environments work, using Community of Inquiry (CoI) as a guiding conceptual framework. This study represented a mixed methods pilot test of a prototype DEER. Twenty-two medical students agreed to participate, and data were collected through qualitative (i.e., focus groups, game-play observations) and quantitative (i.e., questionnaires) methods. Results: Eighty-two per cent of participants agreed or strongly agreed that the DEER supported their learning around uncertainty. Participants offered diverse examples of how the game had facilitated new insights on, and approaches to, uncertainty. With respect to the learning environment, multiple indicators and examples of the three domains of CoI - cognitive, teaching and social presence - were observed. Discussion: Our findings suggested that DEERs offer a valuable online learning environment for students to engage with complex and emotion-provoking challenges, such as those experienced at transitions. The study also suggested that CoI can be applied to the design, implementation, and evaluation of DEER learning environments, and we have proposed a set of design principles that may offer guidance here.

Building digital escape rooms for learning: From theory to practice.

Digital games are increasingly used to support learning across a diverse range of cognitive, affective and psychomotor domains in health professions education. Game-based learning will likely become an important competency for educators. However, educators can perceive game building as out of their reach due to a lack of expertise in digital technology. This toolbox offers advice to health professions educators who would like to build a simple game for learning known as a digital educational escape room.

"Every day that I stay at home, it's another day blaming myself for not being at #Frontline"-Understanding medical students' sacrifices during COVID-19 Pandemic.

COVID-19 struck the world and stretched the healthcare system and professionals. Medical students engaged in the pandemic effort, making personal and professional sacrifices. However, the impact of these sacrifices on students` professional development is still unknown. We applied constructivist grounded theory to individual audio diaries (total time = 5h38 min) and interviews (total time = 11h57min) performed with 18 last-year medical students during the first wave of COVID-19 pandemic in Brazil. The perspective of making sacrifices caused initial emotional distress in medical students, followed by a negotiation process revolving around three themes: predisposition to sacrifice, sense of competence, and sense of belonging. This negotiation process led to three response patterns: Pattern A: "No sense of duty"-the sacrifice was perceived as meaningless, and students showed intense anger and a desire to flee; Pattern B: "Sense of duty with hesitation to act"-the sacrifice was acknowledged as legitime, but students felt unprepared to contribute, leading to feelings of frustration and shame; and, Pattern C: "Sense of duty with readiness to act"-the engagement with the sacrifice was perceived as an opportunity to grow as a doctor, leading to fulfillment and proudness. Students ready to engage with the COVID-19 effort experienced identity consonance, reinforcing their professional identities. Students who felt incompetent or found the sacrifice meaningless experienced identity dissonance, which led to emotional suffering and the consideration of abandoning the course. Monitoring students' emotional reactions when facing professional challenges creates opportunities to problematize the role of sacrifice in the medical profession and scaffold professional identity development.

Palliative care in emergency care: invoking Kairos and rethinking health care systems. / Cuidados paliativos na emergência: invocando Kairós e repensando os sistemas de saúde.

Acute crises of decompensation of a chronic disease are, in most cases, handled in an Emergency Room setting. In these services, emergency care professionals face several challenges, such as incomplete information on the patient's disease, scarce resources, and the pressure of having to make decisions in a short time. In this context, what can be done to provide patient-centered care that is at the same time technically appropriate and aligned with their values? Understanding the patient's situation in relation to their disease; talking to the patient about their clinical condition, comprehending their values and feelings; and understanding time as Kairos - that is, the time of the consultation as an opportunity to understand the patient's needs and build a shared therapeutic plan - are possible solutions to this challenge. Proper handling of patients with severe diseases requires that all links of health care systems are functional and coordinated from primary health care to hospital and home care, starting with the education of health care professionals and the strengthening of work settings that foster the expression of Kairos. This is a long and fundamental path for health care systems such as the Brazilian Unified National Health System (SUS) and that health managers and professionals should not afford to ignore.

Implementation and Assessment of Lung Ultrasound Training Curriculum for Physiotherapists With a Focus on Image Acquisition and Calculation of an Aeration Score.

Described here is the implementation of a lung ultrasound course for physiotherapists focused on the acquisition and retention of knowledge and skills. Initially, we provided online lectures in a virtual learning environment (VLE), in which we taught the semiquantification of edema through a lung ultrasound score (LUS). Afterward, the physiotherapists participated in face-to-face lectures (which resumed the online lectures), followed by hands-on training and simulation with ultrasound. We assessed knowledge acquisition through a multiple-choice test with 30 questions (totaling 10 points). The test was applied before accessing the VLE (pre-VLE), before the face-to-face course and at its end (pre- and post-course). Physiotherapists collected actual patients' ultrasound scans, which were uploaded to the VLE and assessed by three supervisors, who performed a consensus LUS calculation and gave virtual written feedback. Thirteen physiotherapists collected 59 exams. The test results were 3.60 ± 1.58 (pre-VLE), 5.94 ± 1.45 (pre-course) and 8.50 ± 0.71 (post-course), with p < 0.001 for all. The intraclass correlation coefficient for LUS between physiotherapists and supervisors was 0.814 (p < 0.001), with moderate-to-weak agreement for LUS of the lung apical, median and basal zones, with κ = 0.455.334, and 0.417 (p < 0.001 for all). Trainees were found to have increased short-term acquisition and retention of knowledge and skills, with a good intraclass correlation coefficient between them and the consensus of supervisors for the LUS of actual patients.

Social justice in medical education: inclusion is not enough-it's just the first step.

INTRODUCTION: Medical schools worldwide are creating inclusion policies to increase the admission of students from vulnerable social groups. This study explores how medical students from vulnerable social groups experience belongingness as they join the medical community. METHODS: This qualitative study applied thematic analysis to 10 interviews with medical students admitted to one medical school through an affirmative policy. The interviews followed the drawing of a rich picture, in which the students represented a challenging situation experienced in their training, considering their socio-economic and racial background. The analysis was guided by the modes of belonging (engagement, imagination, and alignment) described by the Communities of Practice framework. RESULTS: Participants struggled to imagine themselves as future doctors because they lack identification with the medical environment, suffer from low self-esteem, aside from experiencing racial and social discrimination. Participants also find it troublesome to engage in social and professional activities because of financial disadvantages and insufficient support from the university. However, participants strongly align with the values of the public health system and show deep empathy for the patients. DISCUSSION: Including students with different socio-economic and racial backgrounds offers an opportunity to reform the medical culture. Medical educators need to devise strategies to support students' socialization through activities that increase their self-esteem and make explicit the contributions they bring to the medical community.

Anatomy 3.0: Rediscovering Theatrum Anatomicum in the wake of Covid-19.

The Covid-19 pandemic has challenged medical educators internationally to confront the challenges of adapting their present educational activities to a rapidly evolving digital world. In this article, the authors use anatomy education as proxy to reflect on and remap the past, present, and future of medical education in the face of these disruptions. Inspired by the historical Theatrum Anatomicum (Anatomy 1.0), the authors argue replacing current anatomy dissection laboratory (Anatomy 2.0) with a prototype anatomy studio (Anatomy 3.0). In this studio, anatomists are web-performers who not only collaborate with other foundational science educators to devise meaningful and interactive content but who also partner with actors, directors, web-designers, computer engineers, information technologists, and visual artists to master online interactions and processes in order to optimize students' engagement and learning. This anatomy studio also offers students opportunities to create their own online content and thus reposition themselves digitally, a step into developing a new competency of stage presence within medical education. So restructured, Anatomy 3.0 will prepare students with the skills to navigate an emergent era of tele and digital medicine as well as help to foreshadow forthcoming changes in medical education.

'I found myself a despicable being!': Medical students face disturbing moral dilemmas.

CONTEXT: The psychological realm of medical students' moral experiences is explored tangentially in medical education literature, often in the context of ethics or professionalism education. This study deepens our understanding by (a) investigating the nature of moral dilemmas experienced at the onset of clinical practice, (b) exploring students' emotional response to these dilemmas, and (c) examining how students perceive the influence of these dilemmas on their professional development. METHODS: This is a cross-sectional qualitative study carried out in 2017 that applied thematic template analysis to individual interviews performed with last-year medical students. The interviews followed the drawing of a Rich Picture representing moral dilemmas experienced by medical students at the onset of clinical practice. RESULTS: Moral dilemmas have four intertwined dimensions. The first relates to students' struggle to prioritise, balance and apply conflicting moral values; the second comprises the clash between students' inner motivation and the external constraints that limit the moral action; the third refers to the conflict between students' current attitudes with the desired/idealised attitudes of the doctor they intend to become; and the fourth corresponds to weighting conflicting ethical principles during the moral decision. Students' emotional responses are intense and long-lasting, and with a remarkable residue effect, particularly when the moral decision does not align with their moral beliefs. Moral dilemmas are impactful experiences that affect the professional development of medical students and can culminate in both detachment and growth in moral courage. CONCLUSION: Moral dilemmas are memorable, complex and emotionally intense experiences that impact the professional development of medical students. Understanding students' moral dilemmas can help educators to devise pedagogical activities to anticipate and reflect on these experiences. These activities should happen under the guidance of a non-judgemental facilitator, capable of listening and legitimating students' thoughts and feelings while providing insights to nurture their professional development.

Specific Disease Knowledge as Predictor of Susceptibility to Availability Bias in Diagnostic Reasoning: a Randomized Controlled Experiment.

BACKGROUND: Bias in reasoning rather than knowledge gaps has been identified as the origin of most diagnostic errors. However, the role of knowledge in counteracting bias is unclear. OBJECTIVE: To examine whether knowledge of discriminating features (findings that discriminate between look-alike diseases) predicts susceptibility to bias. DESIGN: Three-phase randomized experiment. Phase 1 (bias-inducing): Participants were exposed to a set of clinical cases (either hepatitis-IBD or AMI-encephalopathy). Phase 2 (diagnosis): All participants diagnosed the same cases; 4 resembled hepatitis-IBD, 4 AMI-encephalopathy (but all with different diagnoses). Availability bias was expected in the 4 cases similar to those encountered in phase 1. Phase 3 (knowledge evaluation): For each disease, participants decided (max. 2 s) which of 24 findings was associated with the disease. Accuracy of decisions on discriminating features, taken as a measure of knowledge, was expected to predict susceptibility to bias. PARTICIPANTS: Internal medicine residents at Erasmus MC, Netherlands. MAIN MEASURES: The frequency with which higher-knowledge and lower-knowledge physicians gave biased diagnoses based on phase 1 exposure (range 0-4). Time to diagnose was also measured. KEY RESULTS: Sixty-two physicians participated. Higher-knowledge physicians yielded to availability bias less often than lower-knowledge physicians (0.35 vs 0.97; p = 0.001; difference, 0.62 [95% CI, 0.28-0.95]). Whereas lower-knowledge physicians tended to make more of these errors on subjected-to-bias than on not-subjected-to-bias cases (p = 0.06; difference, 0.35 [CI, - 0.02-0.73]), higher-knowledge physicians resisted the bias (p = 0.28). Both groups spent more time to diagnose subjected-to-bias than not-subjected-to-bias cases (p = 0.04), without differences between groups. CONCLUSIONS: Knowledge of features that discriminate between look-alike diseases reduced susceptibility to bias in a simulated setting. Reflecting further may be required to overcome bias, but succeeding depends on having the appropriate knowledge. Future research should examine whether the findings apply to real practice and to more experienced physicians.
