Improving uncertainty tolerance in medical students: A scoping review

Evaluation and Comparison of Tolerance of Ambiguity in Veterinary Pathology Professionals and Trainees

Ambiguity is ubiquitous in veterinary medicine, including in clinical and anatomic pathology. Tolerance of ambiguity (TOA) relates to how individuals navigate uncertainty. It is associated with psychological well-being in health professionals yet has been little investigated in veterinarians or veterinary pathologists. In this study, we used the Tolerance of Ambiguity of Veterinary Students (TAVS) scale and eight previously evaluated items specific to clinical pathology to evaluate and compare TOA in pathology professionals and trainees. We hypothesized that scores would be higher (reflecting greater TOA) for professionals than for trainees, that scores would increase with years of diagnostic experience for professionals and year of study for trainees, and that scores would be higher for clinical than anatomic pathologists due to the frequent ambiguity of clinical pathology practice. One hundred eighty one pathology professionals and trainees participated. TAVS scores were significantly higher for professionals than for trainees, and scores increased significantly with year of experience for professionals but not with year of study for trainees. When comparing disciplines, TAVS scores for all clinical pathologists were significantly lower than scores for all anatomic pathologists. Scores for clinical pathology-specific items showed similar trends to TAVS scores, except when comparing disciplines (clinical pathologists tended to have higher scores for these items). Results suggest pathology professionals become more tolerant of ambiguity throughout their careers, independent of increasing TOA with age, and that navigating ambiguity might be more difficult for trainees than for professionals. Educational interventions might help trainees learn to successfully navigate ambiguity, which could impact psychological well-being.

Uncertainty experienced by newly qualified doctors during the transition to internship

INTRODUCTION

Uncertainty is an inherent feature of medical practice. Uncertainty Tolerance (UT) describes how individuals experience and respond to uncertainty, with lower UT associated with negative outcomes, including burnout. Periods of career transition can be particularly uncertain, but there is little research into newly qualified doctors' uncertain experiences during their transition to internship (TTI). Early career doctors have a high incidence of burnout; therefore, understanding how new doctors experience uncertainty could be valuable. We explored the sources of, responses to and moderators of uncertainty during the TTI to inform support of this group.

METHODS

Engaging social constructionism, we conducted a cross-sectional qualitative study with 13 intern doctors who graduated from a single Australian medical school during their TTI. Participants completed a semi-structured interview within five months of commencing practice in 2021. Data were analysed using framework analysis, informed by the integrative UT model.

RESULTS

Although participants described clinical uncertainty during the TTI (i.e. unknown aspects of patient care due to ambiguity, complexity or probability), dominant sources of uncertainty related to novel scenarios (e.g. tasks and responsibilities experienced for the first time) and their professional role (e.g. boundaries and expectations). Participants described responding to uncertainty by asking for help from senior colleagues and reported feelings of stress. Key factors that moderated responses to uncertainty included support, time and perceived stakes.

DISCUSSION

Our results suggest that educators, supervisors and employers should aim to reduce the extraneous uncertainties associated with the TTI. Approaches to achieve this could include orientation programmes that appropriately familiarise interns with workplace environments and systems, reducing role ambiguity by setting clear expectations and facilitating regular feedback, and creating psychologically safe working environments with adequate senior support. These approaches may allow newly qualified doctors the capacity to explore clinical uncertainties and develop their UT through methods such as critical reflection.

Exploring the presence and roles of humility when experiencing situations of uncertainty

Background

Uncertainty is a pervasive challenge in clinical practice. Whereas the importance of humility in navigating uncertainty has been discussed, empirical research on how humility is practiced or expressed (i.e., humility in action) is lacking. This study examines humility's presence and role in physicians' uncertainty experiences during the COVID-19 pandemic. The objectives were to determine if and how humility presented in physicians' reflections on uncertain situations during the height of the COVID-19 pandemic and to explore potential roles of humility in managing uncertainty.

Methods

After intercoder reliability was established, four members of the author team utilized qualitative data analysis software to conduct a secondary analysis of critical incident interviews with 12 physicians (seven ED and five ICU physicians) about experiences with uncertainty while caring for COVID-19 patients. To identify if humility was present in situations of uncertainty, the authors deductively coded transcripts for key elements of humility based on previously published conceptualizations by Tangney (2000) and Gruppen (2015). Additionally, the authors examined code co-occurrence to identify clusters of humility and conducted a thematic analysis to uncover potential roles of humility and what humility "looks like" in clinical situations.

Results

Aspects of humility were frequently present in physicians' narratives. Acknowledgment of shortcomings was most common. Acceptance of limitations, openness, and perspective-taking frequently co-occurred. Two key themes emerged: humility allowed physicians to trust their training despite uncertainty and enabled pivoting and adapting to new information.

Conclusions

Findings suggest that humility facilitates managing uncertainty by promoting trust in abilities and enabling flexibility and openness. Formal training in humility may better prepare clinicians for uncertainty. Further research should explore nuances of humility across clinical situations and types of uncertainty.

Mapping Educational uncertainty stimuli to support health professions educators' in developing learner uncertainty tolerance

Uncertainty is a feature of healthcare practice. In recognition of this, multiple health profession governing bodies identify uncertainty tolerance as a healthcare graduate attribute and evaluate uncertainty tolerance within new graduate cohorts. While it is clear that uncertainty tolerance development for healthcare learners is valued, gaps remain for practically addressing this within healthcare curricula. Guiding frameworks for practical approaches supporting uncertainty tolerance development in healthcare learners remains sparse, particularly outside of medicine and in certain geographical locations. As uncertainty tolerance is increasingly recognised as being, at least in part, state-based (e.g. contextually changeable)- a broader understanding of teaching practices supporting uncertainty tolerance development in diverse health professions is warranted. This study explored educators' teaching practices for purposefully stimulating learners' uncertainty tolerance. Semi-structured interviews investigated how academics at a single institution, from diverse fields and health professions, stimulate uncertainty across multiple learning contexts. Framework analysis identified three themes for stimulating uncertainty: Purposeful questioning, Forecasting uncertainty, and Placing learners in unfamiliar environments, with characterisation of these themes (and related subthemes) also described. Many of the identified themes align with aspects of existing learning theories suggesting that curricular frameworks supporting learner uncertainty tolerance development may be informed by theories beyond the boundaries of health professions education research.

Tolerance for uncertainty and medical students' specialty choices: A myth revisited

BACKGROUND

In 1962, the idea emerged that medical students' tolerance of uncertainty could determine their specialty choice. While some studies supported this claim, others refuted it, often using independently developed instruments. We explored whether the reported link between specialty choice and uncertainty tolerance is more myth than evidence by employing established instruments to investigate whether specialty choice could be explained by variance in uncertainty tolerance.

METHOD

We conducted a cross-sectional online survey at two periods of time. From February to June 2023, we queried 563 final-year medical students from 34 German medical universities (1) on their uncertainty tolerance using three validated tools (the modified tolerance for ambiguity scale, the physicians' reaction to uncertainty scale and the uncertainty intolerance scenario method) and (2) on their intended specialty choice. In a follow-up 1 year later (May to June 2024), 263 of those medical students responded to our query on their final specialty choice and again on their uncertainty tolerance.

RESULTS

Participants' (N = 563) median age was 26.0 years (mean: 27.2; SD = 3.8), and 70% (n = 396) were female. Originally reported differences and rank orders in uncertainty tolerance among medical students with different intended specialty choices could not be replicated for any of the three scales. Instead, our results suggest different rank orders of uncertainty tolerance by different tools, as well as nonsignificant differences between intended medical specialties. Intercorrelation coefficient analyses demonstrated that, depending on the scale, only 0.3% to 1.5% of the variance in uncertainty tolerance could be attributed to specialty choice. Follow-up data using actual instead of intended medical choices left findings unchanged.

DISCUSSION

Our findings suggest that the presumed link between uncertainty tolerance and specialty choice is more myth than evidence. Instead of teaching this link or using it as an admissions criterion, medical schools should equip students with the skills needed to navigate uncertainty across their careers.

The culture of doubt: Do medical students really experience clinical uncertainty when they should?

Uncertainty is a fundamental aspect of medical practice, necessitating incorporation into undergraduate medical training. The integrative model of uncertainty tolerance (UT) developed by Hillen and Han serves as a comprehensive framework for exploring clinical uncertainty. While studies have extensively examined UT dimensions, including sources, responses, and moderators, the factors influencing the perception of uncertainty stimuli remain underexplored. However, students' ability to perceive uncertainty and their approach to uncertain stimuli play a crucial role in enabling them to develop adaptive responses to uncertainty, necessary for their comfort in these situations. Defining uncertainty as a metacognitive state suggests significant variability in its perception among individuals and within an individual over time. Moreover, several studies have demonstrated the substantial influence of various individual and contextual factors on how individuals perceive and respond to uncertainty. In this paper, the authors present multiple hypotheses to address the question of whether students genuinely perceive uncertainty stimuli when they should. The authors argue that students' personal relationship with their knowledge is essential in their ability to identify clinical uncertainty, particularly concerning the limits of medical knowledge. Therefore, they propose that an academic culture fostering doubt, through exposing students to a variety of perspectives, would enhance their ability to identify uncertainty zones in a clinical situation at an early stage. Drawing on Dewey's situational theory, the authors emphasize the importance of better understanding, in a work setting, the influence of contextual and situational characteristics on individual perceptions of uncertainty. In line with this idea, ethnographic studies would offer valuable insights into identifying the relationship between the students, their work environment, and their perception of clinical uncertainty.

"What's Going to Happen?": Internal Medicine Resident Experiences of Uncertainty in the Care of Older Adults

PURPOSE

Internal medicine residents care for clinically complex older adults and may experience increased moral distress due to knowledge gaps, time constraints, and institutional barriers. We conducted a phenomenological study to explore residents' experiences and challenges through the lens of uncertainty.

METHODS

Between January and March 2022, six focus groups were conducted comprising a total of 13 internal medicine residents in postgraduate years 2 and 3, who had completed a required 2-week geriatrics rotation. Applying the Beresford taxonomy of uncertainty as a conceptual model, data were analyzed using the framework method.

RESULTS

All challenging experiences described by residents caring for older adults were linked to uncertainty. Sources of uncertainty were categorized and mapped to the Beresford taxonomy: (1) lack of geriatrics knowledge or clinical guidelines (technical); (2) difficulty applying knowledge to complex older adults (conceptual); and (3) lack of longitudinal relationship with the older patient (personal). Residents identified capacity evaluation and discharge planning as two major geriatric knowledge areas linked with uncertainty. While the majority of residents reacted to uncertainty with some degree of distress, several reported positive coping strategies.

CONCLUSIONS

Internal medicine residents face uncertainty when caring for older adults, particularly related to technical and conceptual factors. Strategies for mitigating uncertainty in the care of older adults are needed given links with moral distress and trainee well-being.

The struggle of dealing with uncertainty: a qualitative, phenomenological study about how Dutch novice physical therapists experience their transition from student to professional

OBJECTIVE

To explain how Dutch novice physical therapists experience their transition from student to physical therapist in private practice.

METHODS

A qualitative, phenomenological study was performed in The Netherlands to collect personal experiences from novice physical therapists who graduated <1 year ago. Data were collected with semi-structured interviews and analyzed using interpretative phenomenological analysis.

RESULTS

The transition experience from student to novice physical therapist is a personal, complex, and context-dependent phenomenon. Sixteen novice physical therapists (of whom 10 were still working in private practice) said their transition was liberating, stressful, insecure, unexpected, chaotic, and challenging. The variety in experiences occurred from the fact that the impact of an experience varies from one individual to the other, depending on their previous (life) experiences, uncertainty tolerance, coping, and personal and professional environment. Four overarching themes emerged: (1) 'Suddenly, I was on my own', (2) 'I was unprepared for the hassle and demands of clinical practice', (3) 'I couldn't make the impact I expected', and (4) 'I had to find a new me'.

CONCLUSIONS

A novice physical therapist's transition is a context-related phenomenon, unique for each individual and determined by individual experiences and coping strategies. Novice physical therapists described a feeling of 'faking': they had to pretend to know what they were doing [while treating a patient] while in reality, they felt like they did not. For some novice physical therapists, a primary reason to leave the profession.

Is emergency doctors' tolerance of clinical uncertainty on a novel measure associated with doctor well-being, healthcare resource use and patient outcomes?

INTRODUCTION

Emergency doctors routinely face uncertainty-they work with limited patient information, under tight time constraints and receive minimal post-discharge feedback. While higher uncertainty tolerance (UT) among staff is linked with reduced resource use and improved well-being in various specialties, its impact in emergency settings is underexplored. We aimed to develop a UT measure and assess associations with doctor-related factors (eg, experience), patient outcomes (eg, reattendance) and resource use (eg, episode costs).

METHODS

From May 2021 to February 2022, emergency doctors (specialty trainee 3 and above) from five Yorkshire (UK) departments completed an online questionnaire. This included a novel UT measure-an adapted Physicians' Reaction to Uncertainty scale collaboratively modified within our team according to Hillen et al's (2017) UT model. The questionnaire also included well-being-related measures (eg, Brief Resilience Scale) and assessed factors like doctors' seniority. Patient encounters involving prespecified 'uncertainty-inducing' problems (eg, headache) were analysed. Multilevel regression explored associations between doctor-level factors, resource use and patient outcomes.

RESULTS

39 doctors were matched with 384 patients. The UT measure demonstrated high reliability (Cronbach's α=0.92) and higher UT was significantly associated with better psychological well-being including greater resilience (Pearson's r=0.56; 95% CI=0.30 to 0.74) and lower burnout (eg, Cohen's d=-2.98; -4.62 to -1.33; mean UT difference for 'no' vs 'moderate/high' burnout). UT was not significantly associated with resource use (eg, episode costs: β=-0.07; -0.32 to 0.18) or patient outcomes including 30-day readmission (eg, OR=0.82; 0.28 to 2.35).

CONCLUSIONS

We developed a reliable UT measure for emergency medicine. While higher UT was linked to doctor well-being, its impact on resource use and patient outcomes remains unclear. Further measure validation and additional research including intervention trials are necessary to confirm these findings and explore the implications of UT in emergency practice.

The impact of a prehospital simulation on medical students' resourcefulness, personal growth initiative, and uncertainty tolerance

Background

Emergency medicine (EM) physicians often practice in dynamic, high-stress, and uncertain settings with limited resources. Although simulation has been shown to enhance various aspects of student development, its impact on medical students' personal growth initiative, resourcefulness, and tolerance of uncertainty-crucial traits for managing future crises as emergency physicians-remain unclear. The purpose of this study, therefore, was to determine a high-fidelity prehospital simulation's impact on medical students' resourcefulness, personal growth, and tolerance of uncertainty.

Methods

We surveyed 107 fourth-year medical students before and after a multiday, high-fidelity prehospital simulation. The survey included items from the Intolerance of Uncertainty Scale-12 Item Form, the Personal Growth Initiative Scale, and the Resourcefulness Skills Scale. We compared students' pre- and post-simulation responses to investigate any change in their uncertainty intolerance, personal growth initiative, and resourcefulness following simulation participation.

Results

Students' scores significantly increased following the simulation for both resourcefulness (t(106) = -6.89, p < 0.001, d = -0.67) and personal growth initiative (t(106) = -6.22, p < 0.001, d = -0.60). Effect size calculations suggest that participating in the simulation had a medium to large effect on participants' resourcefulness and personal growth initiative. However, participants' tolerance of uncertainty scores prior to and following the simulation did not significantly differ (t(106) = 1.66, p = 0.100, d = 0.16), indicating that the simulation had little effect on participants' tolerance of uncertainty.

Conclusions

Our results indicate that simulation is a promising educational tool for developing students' resourcefulness and personal growth initiative so they can navigate high-stress, low-resource environments. Follow-on research is needed to determine how to leverage simulation to enhance students' uncertainty tolerance in high-stress, low-resource environments.

Beliefs and experiences of educators when involved in the design of a Learning-by-concordance tool: A qualitative interpretative study

BACKGROUND

Based on the involvement of qualified educators in its design, the Learning-by-Concordance tool aims to promote the learning of reasoning in contexts of uncertainty. However, data are still scarce on the experience of educators in terms of sharing and exposing their reasoning processes using this tool.

PURPOSE

This study sought to explore the beliefs and experiences of educators when involved in the design of a Learning-by-Concordance tool.

METHOD

This research used a descriptive qualitative design. Four dialogue groups were conducted with educators with different roles and responsibilities while designing a Learning-by-Concordance tool. A descriptive interpretative analysis of educators' verbatim quotes was done.

FINDINGS

A total of 14 participants took part in the study. The results show the discomfort of educators despite their recognized expertise. Three themes emerged: 1- the need to be reassured by the opinions of colleagues; 2-feeling like impostors; and 3- concerns for the quality of instructional supports.

CONCLUSIONS

The role taken by educators for teaching reasoning in contexts of uncertainty is to draw on practical experience where different types of knowledge intersect and are mobilized, to overcome feelings of insecurity, and to engage in close and authentic conversation with learners.

Twelve tips for developing healthcare learners' uncertainty tolerance

BACKGROUND

Uncertainty is pervasive throughout healthcare practice. Uncertainty tolerance (i.e. adaptively responding to perceived uncertainty) is considered to benefit practitioner wellbeing, encourage person-centred care, and support judicious healthcare resource utilisation. Accordingly, uncertainty tolerance development is increasingly referenced within training frameworks. Practical approaches to support healthcare learners' uncertainty tolerance development, however, are lacking.

AIMS

Drawing on findings across the literature, and the authors' educational experiences, twelve tips for promoting healthcare learners' uncertainty tolerance were developed.

RESULTS

Tips are divided into 1. Tips for Learners, 2. Tips for Educators and Supervisors, and 3. Tips for Healthcare Education Institutions and Systems. Each tip summarises relevant research findings, alongside applications to educational practice.

CONCLUSIONS

Approaches to developing uncertainty tolerance balance factors supporting learners through uncertain experiences, with introducing challenges for learners to further develop uncertainty tolerance. These tips can reassure healthcare education stakeholders that developing learner uncertainty tolerance, alongside core knowledge, is achievable.

'I was uncertain, but I was acting on it': A longitudinal qualitative study of medical students' responses to uncertainty

PURPOSE

Uncertainty is ubiquitous within medical practice. Accordingly, how individuals respond to uncertainty, termed uncertainty tolerance (UT), is increasingly considered a medical graduate competency. Despite this, aspects of the UT construct are debated, which may relate to research focused on measuring UT, rather than understanding students' experiences. Therefore, we asked (1) how do medical students describe their responses to uncertainty, (2) how (if at all) do described responses change over time and (3) how do described responses contribute to understanding the UT construct.

METHODS

Engaging an interpretivist worldview, we conducted a longitudinal qualitative study throughout 2020 with 41 clinical medical students at an Australian medical school. Participants completed reflective diary entries across six in-semester time-points (n = 41, 40, 39, 38, 37 and 35) and semi-structured interviews at the end of both semesters (n = 20 per semester). We analysed data using framework analysis.

RESULTS

Although participants communicated accepting health care uncertainties, described cognitive appraisals of uncertainty ranged from threatening (e.g. challenging credibility) to opportunistic (e.g. for learning and growth). Emotions in response to uncertainty were predominately described in negative terms, including worry and anxiety. Participants described a range of maladaptive and adaptive behavioural responses, including avoiding versus actively engaging with uncertainty. Despite describing typically negative emotions across time, participants' cognitive and behavioural response descriptions shifted from self-doubt and avoidance, towards acceptance of, and engagement despite uncertainty.

CONCLUSIONS

Students' descriptions of responses to uncertainty suggest existing UT conceptualisations may not holistically reflect medical students' experiences of what it means to be uncertainty 'tolerant', especially pertaining to conceptualisations of 'tolerance' centred on emotions (e.g. stress) rather than how uncertainty is ultimately managed. Extending from this study, the field could consider redefining characteristics of uncertainty 'tolerance' to focus on adaptive cognitive and behavioural responses, rather than emotional responses as key indicators of 'tolerance'.

Learning to navigate uncertainty in primary care: a scoping literature review

BACKGROUND

Clinical practice occurs in the context of uncertainty. Primary care is a clinical environment that accepts and works with uncertainty differently from secondary care. Recent literature reviews have contributed to understanding how clinical uncertainty is taught in educational settings and navigated in secondary care, and, to a lesser extent, by experienced GPs. We do not know how medical students and doctors in training learn to navigate uncertainty in primary care.

AIM

To explore what is known about primary care as an opportunity for learning to navigate uncertainty.

DESIGN & SETTING

Scoping review of articles written in English.

METHOD

Using a scoping review methodology, Embase, MEDLINE, and Web of Science databases were searched, with additional articles obtained through citation searching. Studies were included in this review if they: (a) were based within populations of medical students and/or doctors in training; and (b) considered clinical uncertainty or ambiguity in primary care or a simulated primary care setting. Study findings were analysed thematically.

RESULTS

Thirty-six studies were included from which the following three major themes were developed: uncertainty contributes to professional identity formation (PIF); adaptive responses; and maladaptive behaviours. Relational and social factors that influence PIF were identified. Adaptive responses included adjusting epistemic expectations and shared decision making (SDM).

CONCLUSION

Educators can play a key role in helping learners navigate uncertainty through socialisation, discussing primary care epistemology, recognising maladaptive behaviours, and fostering a culture of constructive responses to uncertainty.

Systematic Search and Scoping Review of Physicians' Intolerance of Uncertainty and Medical Decision-Making Uncertainties During the COVID-19 Pandemic: A Summary of the Literature and Directions for Future Research

Pandemic-related uncertainties and intolerance of uncertainty (IU) could negatively affect physicians' well-being and functioning, being associated with experiences of distress and problematic decision-making processes. To summarize the available quantitative and qualitative evidence of physicians' IU and decisional uncertainty during COVID-19 and problems associated with it, a systematic search was conducted to identify all relevant articles describing physician uncertainty with regard to medical decision making and well-being in COVID-19 pandemic conditions. Medical, psychological, and preprint databases were searched. Ten articles met all eligibility criteria, with eight describing quantitative and two describing qualitative research outcomes, assessed primarily in European regions and via online surveys. Associations between IU and symptoms of poor mental health and mental health risk factors were widespread, but inconsistencies emerged. Qualitative studies emphasized decisional uncertainty as a stressor for physicians, and quantitative studies suggest it may have fostered more unproven treatment choices. While the prevalence and impact of physician uncertainty under COVID-19 conditions requires further investigation, sighting available literature indicates that IU coincided with experiences of poor mental health and, at least towards the beginning of the pandemic, with willingness to endorse unproven treatments. Efforts to reduce uncertainty-related problems for physicians seem warranted, for example, through normalizing experiences of uncertainty or reducing avoidable uncertainty through maintaining open and timely communication channels.

Languaging psychopathology: neurobiology and metaphor

Explanatory models of the mind inform our working assumptions about mental illness with direct implications for clinical practice. Neurobiological models assert that the mind can be understood in terms of genetics, chemistry, and neuronal circuits. Growing evidence suggests that clinical deployment of neurobiological models of illness may have unintended adverse effects on patient attitudes, public perception, provider empathy, and the effectiveness of psychiatric treatment. New approaches are needed to find a better language for describing (let alone explaining) the experience of mental illness. To address this gap, we draw upon interdisciplinary sources and semiotic theory to characterize the role of metaphor in the conceptualization and communication of psychopathology. We examine the metaphors recruited by contemporary neurobiological models and metaphor's role in facilitating descriptive clarity or evocative creativity, depending on intention and context. These multiple roles reveal the implications of metaphorical reasoning in clinical practice, including cognitive flexibility, personalized communication, and uncertainty tolerance. With this analysis, we propose a clinical approach that embraces the meta-process of ongoing novel metaphor generation and co-elaboration, or languaging metaphors of psychopathology. Our goal is to bring attention to the value of employing ever-evolving, shapeable metaphorical depictions of psychiatric illness: metaphors that enable a capacity for change in individuals and society, reduce stigma, and nurture recovery.

Defining and unpacking the core concepts of pharmacology: A global initiative

BACKGROUND AND PURPOSE

Development of core concepts in disciplines such as biochemistry, microbiology and physiology have transformed teaching. They provide the foundation for the development of teaching resources for global educators, as well as valid and reliable approaches to assessment. An international research consensus recently identified 25 core concepts of pharmacology. The current study aimed to define and unpack these concepts.

EXPERIMENTAL APPROACH

A two-phase, iterative approach, involving 60 international pharmacology education experts, was used. The first phase involved drafting definitions for core concepts and identifying key sub-concepts via a series of online meetings and asynchronous work. These were refined in the second phase, through a 2-day hybrid workshop followed by a further series of online meetings and asynchronous work.

KEY RESULTS

The project produced consensus definitions for a final list of 24 core concepts and 103 sub-concepts of pharmacology. The iterative, discursive methodology resulted in modification of concepts from the original study, including change of 'drug-receptor interaction' to 'drug-target interaction' and the change of the core concept 'agonists and antagonists' to sub-concepts of drug-target interaction.

CONCLUSIONS AND IMPLICATIONS

Definitions and sub-concepts of 24 core concepts provide an evidence-based foundation for pharmacology curricula development and evaluation. The next steps for this project include the development of a concept inventory to assess acquisition of concepts, as well as the development of case studies and educational resources to support teaching by the global pharmacology community, and student learning of the most critical and fundamental concepts of the discipline.

Unlocking the learning potential of simulation-based education

Simulation is ubiquitous in the training of hospital-based doctors worldwide, often focusing on an individual level in traditional 'skills and drills'-based training. However, there has been an expansion in the use of simulation in healthcare practice and training. Simulation is being adopted into many disciplines that traditionally have not used this form of experiential learning. Moreover, simulation is increasingly being harnessed to enhance team and organisational learning in hospital-based practice. This article shares some insights into simulation-based education and makes the 'familiar unfamiliar' about this important method of learning. The aim is to broaden readers' outlook about what simulation has to offer beyond the classic notion of skills and drills-based training.

Measurement of uncertainty tolerance revisited

INTRODUCTION

Uncertainty tolerance (UT) is attracting increasing attention in medical education due to the numerous challenges associated with uncertainty in professional life. Inconsistencies in analysing the relationship between UT and moderators may arise from inadequate measurement methods. Most instruments were formulated before the most widely accepted framework was published. Our aim was to investigate the validity of an UT scale using an actual framework to corroborate with better and accurate instruments.

METHODS

A total of 1052 students were invited. Various psychometric methods were used to explore validity of the TAMSAD scale in light of actual framework. Classic exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed. Secondly, content item classification was triangulated with exploratory graph analysis (EGA), and the new EFA, CFA, and cognitive diagnostic modelling (CDM) analysis were conducted. The reliability was calculated using Cronbach's alpha and McDonald's omega.

RESULTS

A total of 694 students (65.9%) responded to the questionnaire. The reliability of the TAMSAD scale was 0.782. The initial EFA revealed no clear interpretable dimensions. The TAMSAD scale items can be classified into sources of uncertainty. The EGA has three dimensions, and the new EFA led to a 17-item TAMSAD scale with the following three dimensions: ambiguity, complexity, and probability. These dimensions lead to better adjustment fit indices in the new CFA and CDM analyses.

CONCLUSION

We found evidence that the TAMSAD scale can be considered a multidimensional scale, organised in terms of sources of uncertainty.

The chain mediating role of psychological resilience and neuroticism between intolerance of uncertainty and perceived stress among medical university students in Southwest China

BACKGROUND

Medical university students are confronted with unprecedented uncertainty and stress compared with their peers. Research has explored the effect of intolerance of uncertainty on perceived stress, but little attention was paid to investigate the mediating mechanisms behind this relationship, especially among medical university students. The aim of this study was to examine whether psychological resilience and neuroticism played a mediating role between medical university students' intolerance of uncertainty and perceived stress.

METHODS

A total of 717 medical university students from Chongqing in Southwest China were recruited to participate in our study and completed demographic information, Intolerance of Uncertainty Scale Short Version (IUS-12), Chinese Version of Perceived Stress Scale (CPSS), Connor-Davidson Resilience Scale-10 (CD-RISC-10) and Eysenck Personality Questionnaire (EPQ).

RESULTS

(1) Significant correlations between intolerance of uncertainty, perceived stress, psychological resilience and neuroticism were found. (2) Intolerance of uncertainty affected medical university students' perceived stress via three paths: the mediating effect of psychological resilience, the mediating effect of neuroticism, and the chain mediating effect of both psychological resilience and neuroticism.

CONCLUSIONS

Intolerance of uncertainty could directly affect the perceived stress of medical university students, and also affected perceived stress through the mediating roles of psychological resilience and neuroticism, as well as through the chain mediating role of these two variables.

Making decisions "in the dark": Learning through uncertainty in clinical practice during Covid-19

Purpose

The purpose of this study was to explore how decision making and informal and incidental learning (IIL) emerged in the clinical learning environment (CLE) during the height of the Covid-19 pandemic. The authors' specific interest was to better understand the IIL that took place among frontline physicians who had to navigate a CLE replete with uncertainty and complexity with the future goal of creating experiences for medical students that would simulate IIL and use uncertainty as a catalyst for learning.

Method

Using a modified constructivist, grounded theory approach, we describe physicians' IIL while working during times of heightened uncertainty. Using the critical incident technique, we conducted 45-min virtual interviews with seven emergency department (ED) and five intensive care unit (ICU) physicians, who worked during the height of the pandemic. The authors transcribed and restoried each interview before applying inductive, comparative analysis to identify patterns, assertions, and organizing themes.

Results

Findings showed that the burden of decision making for physicians was influenced by the physical, emotional, relational, and situational context of the CLE. The themes that emerged for decision making and IIL were interdependent. Prominent among the patterns for decision making were ways to simplify the problem by applying prior knowledge, using pattern recognition, and cross-checking with team members. Patterns for IIL emerged through trial and error, which included thoughtful experimentation, consulting alternative sources of information, accumulating knowledge, and "poking at the periphery" of clinical practice.

Conclusions

Complexity and uncertainty are rife in clinical practice and this study made visible decision-making patterns and IIL approaches that can be built into formal curricula. Making implicit uncertainty explicit by recognizing it, naming it, and practicing navigating it may better prepare learners for the uncertainty posed by the clinical practice environment.

Uncertainty tolerance scales: Weighing up the research

Patel and Hancock explore the uncertainty tolerance literature to determine how it ties in with quantitive scales developed to measure uncertainty tolerance.

Measuring grit, self-efficacy, curiosity, and intolerance of uncertainty in first-generation college and first-generation osteopathic medical students

BACKGROUND

Medical school is a challenging time, with many medical students reporting symptoms of burnout, depression, anxiety, suicidal ideation, and psychological distress during pre-clinical and clinical years. First-generation college and first-generation medical students may be two groups of students at increased risk for the negative psychosocial effects of medical school. Importantly, grit, self-efficacy, and curiosity are protective factors against the negative psychosocial effects of medical school, whereas intolerance of uncertainty is a risk factor. Thus, research examining the associations among grit, self-efficacy, curiosity, and intolerance of uncertainty in first-generation college and first-generation medical students is needed.

METHODS

We conducted a cross-sectional, descriptive study to assess medical students' grit, self-efficacy, curiosity, and intolerance of uncertainty. We conducted independent samples t-tests and regression analyses using SPSS statistical software version 28.0.

RESULTS

A total of 420 students participated in the study for a response rate of 51.5%. One-fifth of participants (21.2%, n = 89) identified as first-generation students, 38.6% (n = 162) participants reporting having a physician relative, and 16.2% (n = 68) reported having a physician parent. Grit, self-efficacy, and curiosity and exploration scores did not differ by first-generation college status, physician relative(s), or physician parent(s). However, total intolerance of uncertainty scores differed by physician relative(s) (t= -2.830, p = 0.005), but not by first-generation status, or physician parent(s). Further, subscale scores for prospective intolerance of uncertainty differed by physician relative(s) (t= -3.379, p = 0.001) and physician parent(s) (t= -2.077, p = 0.038), but not by first-generation college student status. In the hierarchical regression models, first-generation college student status and first-generation medical student status were not predictive of grit, self-efficacy, curiosity and exploration, or intolerance of uncertainty, although statistical trends were observed with students with physician relative(s) predicting lower intolerance of uncertainty scores (B= -2.171, t= -2138, p = 0.033) and lower prospective intolerance of uncertainty (B= -1.666, t= -2.689, p = 0.007).

CONCLUSIONS

These findings suggest that first-generation college students did not differ by grit, self-efficacy, curiosity, or intolerance of uncertainty. Similarly, first-generation medical students did not differ by grit, self-efficacy, or curiosity; however, first-generation medical students showed statistical trends in higher total intolerance of uncertainty and higher prospective intolerance of uncertainty. Additional research needs to confirm these findings in first-generation medical students.

Intolerance of uncertainty and attitudes towards persons living with disabilities in medical students: Is there a correlation?

Introduction

Patients living with a disability experience an illness trajectory that may be uncertain. While navigating clinical uncertainty has been well-researched, health professionals' intolerance of uncertainty for patients living with disabilities has yet to be explored. We examined the relationship between medical students' intolerance of uncertainty with their attitudes towards people living with disabilities to better inform curricular efforts.

Methods

We employed a survey-based design consisting of the Intolerance of Uncertainty Scale (IUS) and Disability Attitudes in Healthcare (DAHC) Scale to medical students upon completion of core clerkships (end of third-year of training). Data were de-identified. Mean DAHC and IUS scores were compared with published values via t-test. Linear regression was used to examine IUS/DAHC scores for anonymized students. Pearson correlation coefficient was calculated to assess correlation between IUS and DAHC scores.

Results

Response rate was 97% (268/275 students). Mean IUS score did not differ from previously cited medical student scores, but mean DAHC score was significantly higher than previously cited scores. We observed a statistically-significant relationship between IUS and DAHC scores. Students with greater intolerance of uncertainty had lower scores for disability attitudes [F(1,243) = 8.05, value of p < 0.01], with an R ²-value of 0.032, suggesting that 3% of DAHC score variance can be explained by IUS score changes.

Conclusion

We identified a weak negative correlation between IUS and DAHC scores in medical students. Further research is needed to clarify findings and identify best practices that equip trainees with skills to care for patients with uncertain illness trajectories and patients living with disabilities.

[Tolerating uncertainty: Towards a competence-based approach]

Uncertainty in inherent to every aspects of medical practice. As the concept of uncertainty in healthcare is still to explore, deciphering the determinants and the roots of this uncertainty would benefit from the insights of various disciplines, such as epistemology, sociology, mathematics, or philosophy. The urgent need to improve physician's ability to cope with uncertainty, has been recently highlighted by the COVID-19 pandemic. Besides, the concept of uncertainty tolerance has been proposed, and could serve as a relevant basis for approaching uncertainty, in medical education. Thus, we propose at first to discuss the uncertainty tolerance framework from Hillen et al. Then, from an educational perspective, we outline some avenues regarding how uncertainty tolerance could be thought, in a competence-based approach, and discuss several educational activities, which have proven efficient in promoting uncertainty tolerance among medical practitioners abroad.

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.
