The influence of a digital clinical reasoning test on medical student learning behavior during clinical clerkships.

Recently, a new digital clinical reasoning test (DCRT) was developed to evaluate students' clinical-reasoning skills. Although an assessment tool may be soundly constructed, it may still prove inadequate in practice by failing to function as intended. Therefore, more insight is needed into the effects of the DCRT in practice. Individual semi-structured interviews and template analysis were used to collect and process qualitative data. The template, based on the interview guide, contained six themes: (1) DCRT itself, (2) test debriefing, (3) reflection, (4) practice/workplace, (5) DCRT versus practice and (6) 'other'. Thirteen students were interviewed. The DCRT encourages students to engage more in formal education, self-study and workplace learning during their clerkships, particularly for those who received insufficient results. Although the faculty emphasizes the different purposes of the DCRT (assessment of/as/for learning), most students perceive the DCRT as an assessment of learning. This affects their motivation and the role they assign to it in their learning process. Although students appreciate the debriefing and reflection report for improvement, they struggle to fill the identified knowledge gaps due to the timing of receiving their results. Some students are supported by the DCRT in exhibiting lifelong learning behavior. This study has identified several ways in which the DCRT influences students' learning practices in a way that can benefit their clinical-reasoning skills. Additionally, it stresses the importance of ensuring the alignment of theoretical principles with real-world practice, both in the development and utilization of assessment tools and their content. Further research is needed to investigate the long-term impact of the DCRT on young physicians' working practice.

Reasoning like a doctor or like a nurse? A systematic integrative review.

When physicians and nurses are looking at the same patient, they may not see the same picture. If assuming that the clinical reasoning of both professions is alike and ignoring possible differences, aspects essential for care can be overlooked. Understanding the multifaceted concept of clinical reasoning of both professions may provide insight into the nature and purpose of their practices and benefit patient care, education and research. We aimed to identify, compare and contrast the documented features of clinical reasoning of physicians and nurses through the lens of layered analysis and to conduct a simultaneous concept analysis. The protocol of this systematic integrative review was published doi: 10.1136/bmjopen-2021-049862. A comprehensive search was performed in four databases (PubMed, CINAHL, Psychinfo, and Web of Science) from 30th March 2020 to 27th May 2020. A total of 69 Empirical and theoretical journal articles about clinical reasoning of practitioners were included: 27 nursing, 37 medical, and five combining both perspectives. Two reviewers screened the identified papers for eligibility and assessed the quality of the methodologically diverse articles. We used an onion model, based on three layers: Philosophy, Principles, and Techniques to extract and organize the data. Commonalities and differences were identified on professional paradigms, theories, intentions, content, antecedents, attributes, outcomes, and contextual factors. The detected philosophical differences were located on a care-cure and subjective-objective continuum. We observed four principle contrasts: a broad or narrow focus, consideration of the patient as such or of the patient and his relatives, hypotheses to explain or to understand, and argumentation based on causality or association. In the technical layer a difference in the professional concepts of diagnosis and the degree of patient involvement in the reasoning process were perceived. Clinical reasoning can be analysed by breaking it down into layers, and the onion model resulted in detailed features. Subsequently insight was obtained in the differences between nursing and medical reasoning. The origin of these differences is in the philosophical layer (professional paradigms, intentions). This review can be used as a first step toward gaining a better understanding and collaboration in patient care, education and research across the nursing and medical professions.

Illness scripts in nursing: Directed content analysis.

AIMS: To explore the possible extension of the illness script theory used in medicine to the nursing context. DESIGN: A qualitative interview study. METHODS: The study was conducted between September 2019 and March 2020. Expert nurses were asked to think aloud about 20 patient problems in nursing. A directed content analysis approach including quantitative data processing was used to analyse the transcribed data. RESULTS: Through the analysis of 3912 statements, scripts were identified and a nursing script model is proposed; the medical illness script, including enabling conditions, fault and consequences, is extended with management, boundary, impact, occurrence and explicative statements. Nurses often used explicative statements when pathophysiological causes are absent or unknown. To explore the applicability of Illness script theory we analysed scripts' richness and maturity with descriptive statistics. Expert nurses, like medical experts, had rich knowledge of consequences, explicative statements and management of familiar patient problems. CONCLUSION: The knowledge of expert nurses about patient problems can be described in scripts; the components of medical illness scripts are also relevant in nursing. We propose to extend the original illness script concept with management, explicative statements, boundary, impact and occurrence, to enlarge the applicability of illness scripts in the nursing domain. IMPACT: Illness scripts guide clinical reasoning in patient care. Insights into illness scripts of nursing experts is a necessary first step to develop goals or guidelines for student nurses' development of clinical reasoning. It might lay the groundwork for future educational strategies.

Support for using a three-dimensional anatomy application over anatomical atlases in a randomized comparison.

To investigate to what extent the use of a three-dimensional (3D) anatomy computer application can improve the acquisition of anatomical knowledge compared with anatomical atlases, junior and advanced medical students participated in an experiment. Participants were asked to answer anatomical questions with the use of a 3D anatomy application (developed at the University Medical Center in Utrecht, the Netherlands) or anatomy atlases. Every student had to complete two assignments, either with an atlas or with the 3D anatomy application. One assignment consisted of 20 questions about the anatomy of the hand, the other one had 20 questions about the anatomy of the foot. The scores on the assignments and time to complete the assignments were registered and investigated. A total of 76 students participated. Students scored significantly higher and were significantly faster when they used the 3D anatomy application. Junior medical students were significantly faster than advanced medical students and particularly, advanced students who worked with an atlas needed most time. These results suggest that the 3D anatomy application is more effective as a studying tool, when compared to the use of paper atlases, for both junior and advanced medical students. The difference in time could indicate an influence of the increased number of mental steps it takes to convert two-dimensional atlas images to a 3D mental representation compared to using the 3D anatomy application, although practical issues explaining this cannot be ruled out. Future studies should establish whether the application leads to better learning/retention and to more time-efficient studying.

Assessing Knowledge of Pharmacokinetics in an Integrated Medical Curriculum.

Pharmacokinetics is the branch of pharmacology that describes how the body processes drugs. As most physicians will prescribe drugs during their career, knowledge of pharmacokinetics is indispensable for medical students. Students, however, experience pharmacokinetics as difficult, probably due to its abstract and mathematical nature. In many medical curricula, pharmacokinetic topics are taught and examined as a part of integrated medical courses. As pharmacokinetics is a relatively small subject, unit examinations contain only few questions on the topic. The combination of a difficult subject and a few questions has raised concerns that students could perform poorly in pharmacokinetics and still pass the examinations and, hence, end up with insufficient knowledge of pharmacokinetics. In this study, we investigate this issue by contrasting students' performance on pharmacokinetics questions with their performance on the rest of the examinations (all non-pharmacokinetics questions lumped together). The results expressed as pass-fail scores showed that students failed more often on the pharmacokinetics part of the test than on the other questions, in two consecutive academic years. Despite the suboptimal knowledge in pharmacokinetics, students can still acquire their bachelor's degree. These results show that poor knowledge in pharmacokinetics could be a side effect of curricular integration. Attention should therefore be paid to provide insight into one's own performance in individual disciplines. This would avoid knowledge deficiency and incompetence in the future.

Reasoning like a doctor or like a nurse? An integrative review protocol.

INTRODUCTION: Clinical reasoning, a major competency for all health professionals, has been defined and studied 'within' each profession. We do not know if content, process and outcomes are comparable 'between' physician and nursing clinical reasoning. This paper aims to set up a protocol for an integrative review to analyse and synthesise the scientific nursing and medical clinical reasoning literature. It builds on the history of nursing and medical clinical reasoning research and aims to create a higher level of conceptual clarity of clinical reasoning, to increase mutual understanding in collaboration in patient care, education and research. METHODS AND ANALYSIS: This integrative review follows stepwise the methods described by Whittmore and Knafl: problem identification, literature search, data evaluation, data analysis and presentation.The initial systematic and comprehensive search strategy is developed in collaboration with the clinical librarian and is performed in electronic databases, PubMed, CINAHL, PsycInfo and Web of Science from 30 March 2020 to 27 May 2020. Empirical and theoretical studies are included. This search will be accompanied by ancestry searching and purposeful sampling. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow chart will summarise the selection process. The quality of eligible studies will be evaluated with a checklist, suitable for diverse study methods.The data analysis is inspired by concept analysis of Walker and Avant and layered analysis of an intervention of Cianciolo and Regehr. We will extract the data of the included studies conforming these layers and features, to capture the multifaceted nature of clinical reasoning in both professions. The data will be presented in a validity matrix to facilitate comparing and contrasting. ETHICS AND DISSEMINATION: Ethics approval is not required. The outcomes will be disseminated through conference presentations and publications.

Fundamentals of randomized designs: AMEE Guide No. 128.

This AMEE Guide summarizes fundamentals of a major experimental design option for medical education researchers: the randomised study. Medical education researchers face an overwhelming taxonomy of study design options; given the breadth of information on experimental design, the purpose of this Guide is to offer a resource for medical education researchers wishing to equip themselves with helpful information for when to match a study's objective and the use of randomised designs. Once a research question has been formulated study design is the cornerstone of the intricate, nested activities of any research project. Researchers negotiate many decisions in the pursuit of choosing an appropriate design approach; failure to do so can undermine a project's capacity to, for example, sufficiently test a hypothesis or theory. Written as an introduction, this Guide is intended for medical education researchers seeking to build on and synthesise the existing corpus of literature on experimental and quasi-experimental design approaches. While not comprehensive, presented are key concepts alongside relevant examples from the field of health professions education.

Approaches of anatomy teaching for seriously resource-deprived countries: A literature review.

Background: Teaching anatomy is an important but expensive part of the medical curriculum, potentially more than many countries can afford. In the search for efficient methods, cost-effectiveness is of utmost importance for such countries. The aim of this contribution is to provide a review of the literature on anatomy teaching methods, evaluating these for feasibility in resource-deprived countries. Methods: A literature review was carried out to identify distinct approaches to anatomy teaching published in the period 2000-2014, using the databases of PubMed, Wiley Online Library, Elsevier, HINARI, Springer, and ERIC. The approaches found were compared against their conceptual, operational, technical, and economic feasibility and Mayer's principles of effective instruction. Results: Our search yielded 432 papers that met the inclusion criteria. We identified 14 methods of teaching anatomy. Based on their conceptual feasibility, dissection and technology enhanced learning approaches appeared to have more benefits than others. Dissection has, besides benefits, many specific drawbacks. Lectures and peer teaching showed better technical and economic feasibility. Educational platforms, radiological imaging, and lectures showed the highest operational feasibility. Dissection and surgery were found to be less feasible with regard to operational, technical, and economic characteristics. Discussion: Based on our findings, the most important recommendations for anatomy teaching in seriously resource-deprived countries include a combination of complementary strategies in 3 different moments, lecturing at the beginning, using virtual learning environment (for self-study), and at the end, using demonstration through prosected specimens and radiological imaging. This provides reasonable insights in anatomy through both dead and living human bodies and their virtual representations.

Theories of truth and teaching clinical reasoning and problem solving.

In this paper, we will first discuss two current meta-theories dealing with different, aspects of "truth". The first metatheory conceives of truth in terms of coherence (rationality, consistency): a body of knowledge is true when it contains no inconsistencies and has at least some credibility. The second metatheory conceives of truth as correspondence, i.e., empirical accuracy. The two metatheories supplement each other, but are also incommensurable, i.e., they cannot be expressed in each other's terms, for they employ completely different criteria to establish truth (Englebretsen in Bare facts and naked truths: a new correspondence theory of truth, Routledge, London, 2005). We will discuss both the role of both metatheories in medicine, in particular in medical education in a clinical context. In line with Hammond's view (Med Decis Mak 16(3):281-287, 1996a; Human judgment and social policy: irreducible uncertainty, inevitable error, unavoidable injustice, Oxford University Press, New York, 1996b), we will extend the two metatheories to two forms of competence: coherence competence and correspondence competence, and demonstrate that distinguishing these two forms of competence increases our insights as to the best way to teach undergraduate students clinical problem solving.

Does an Additional Online Anatomy Course Improve Performance of Medical Students on Gross Anatomy Examinations?

AIM: An online learning course in anatomy was added to the regular academic anatomy course in the 2nd year of medicine at UNAN-Leon in Nicaragua, using the MOODLE platform. This study aims to determine the learning effect of this course. METHOD: Second-year medical students were randomly allocated to an experimental (N = 25) and control group (N = 50). Only the experimental group had access to the online learning module. We compared the performance of the experimental and the control group on both regular anatomy assessment and an objective structured practical exam (OSPE). Additionally, five focus groups were interviewed to learn about their experiences of the expanded course. RESULTS: Of students in the experimental group 94.1% and 81.6% of students in the control group took the OSPE. The experimental group significantly outperformed the control group (41.1 ± 19.3 points vs. 32.1 ± 23.1 points) on the OSPE. No differences between the two groups were found on the regular anatomy examination. Focus group interviews revealed students' opinions about the online course were generally positive. CONCLUSION: In general, the addition of an online course to the regular course was beneficial. The results of the qualitative evaluation of this intervention provides us with input about how to teach and evaluate the anatomy course and how to further improve the online course to enhance anatomy learning.

Comparing the critical features of e-applications for three-dimensional anatomy education.

Anatomical e-applications are increasingly being created and used in medical education and health care for the purpose of gaining anatomical knowledge. Research has established their superiority over 2D methods in the acquisition of spatial anatomy knowledge. Many different anatomy e-applications have been designed, but a comparative review is still lacking. We aimed to create an overview for comparing the features of anatomy e-applications in order to offer guidance in selecting a suitable anatomy e-application. A systematic search was conducted. Data were retrieved from the 3D model designs (realism), software aspects and program functionality. The non-commercial e-applications focused on small body regions and received an average score of 3.04 (range 1-5) for model realism. Their average score on program functionality was 8.8 (range 0-14). The commercial e-applications covered the entire human body and received an average score of 2.85 (range 1-5) for model realism. Their average score on program functionality was 10.4 (range 0-14). Non-commercial anatomy e-applications received higher scores on realism and facilities like performing a virtual dissection, while the commercial anatomy e-applications offer a much wider range of anatomical structures available and they showed higher scores on program functionality. These scores gave good insight of the e-applications' possibilities, and may help future users to make an informed choice among the large number of available e-applications.

The History of Medical Education in Europe and the United States, With Respect to Time and Proficiency.

In this article, the authors present a historic overview of the development of medical education in the United States and Europe (in particular the Netherlands), as it relates to the issues of time (duration of the course) and proficiency (performance requirements and examinations). This overview is necessarily limited and based largely on post hoc interpretation, as historic data on time frames are not well documented and the issue of competence has only recently been addressed.During times when there were few, if any, formal regulations, physicians were primarily "learned gentlemen" in command of few effective practical skills, and the duration of education and the competencies acquired by the end of a course simply did not appear to be issues of any interest to universities or state authorities. Though uniform criteria gradually developed for undergraduate medical education, postgraduate specialty training remained, before accreditation organizations set regulations, at the discretion of individual institutions and medical societies. This resulted in large variability in training time and acquired competencies between residency programs, which were often judged on the basis of opaque or questionable criteria. Considering the high costs of health care today and the increasing demand for patient safety and educational efficiency, continuing historic models of nonstandardized practices will no longer be feasible. Efforts to constrain, restructure, and individualize training time and licensing tracks to optimize training for safe care, both in the United States and Europe, are needed.

Illness script development in pre-clinical education through case-based clinical reasoning training.

OBJECTIVES: To assess illness script richness and maturity in preclinical students after they attended a specifically structured instructional format, i.e., a case based clinical reasoning (CBCR) course. METHODS: In a within-subject experimental design, medical students who had finished the CBCR course participated in an illness script experiment. In the first session, richness and maturity of students' illness scripts for diseases discussed during the CBCR course were compared to illness script richness and maturity for similar diseases not included in the course. In the second session, diagnostic performance was tested, to test for differences between CBCR cases and non-CBCR cases. Scores on the CBCR course exam were related to both experimental outcomes. RESULTS: Thirty-two medical students participated. Illness script richness for CBCR diseases was almost 20% higher than for non-CBCR diseases, on average 14.47 (SD=3.25) versus 12.14 (SD=2.80), respectively (p<0.001). In addition, students provided more information on Enabling Conditions and less on Fault-related aspects of the disease. Diagnostic performance was better for the diseases discussed in the CBCR course, mean score 1.63 (SD=0.32) versus 1.15 (SD=0.29) for non-CBCR diseases (p<0.001). A significant correlation of exam results with recognition of CBCR cases was found (r=0.571, p<0.001), but not with illness script richness (r=-0.006, p=NS). CONCLUSIONS: The CBCR-course fosters early development of clinical reasoning skills by increasing the illness script richness and diagnostic performance of pre-clinical students. However, these results are disease-specific and therefore we cannot conclude that students develop a more general clinical reasoning ability.

Influence of learner knowledge and case complexity on handover accuracy and cognitive load: results from a simulation study.

CONTEXT: The handover represents a high-risk event in which errors are common and lead to patient harm. A better understanding of the cognitive mechanisms of handover errors is essential to improving handover education and practice. OBJECTIVES: This paper reports on an experiment conducted to study the effects of learner knowledge, case complexity (i.e. cases with or without a clear diagnosis) and their interaction on handover accuracy and cognitive load. METHODS: Participants were 52 Dutch medical students in Years 2 and 6. The experiment employed a repeated-measures design with two explanatory variables: case complexity (simple or complex) as the within-subject variable, and learner knowledge (as indicated by illness script maturity) as the between-subject covariate. The dependent variables were handover accuracy and cognitive load. Each participant performed a total of four simulated handovers involving two simple cases and two complex cases. RESULTS: Higher illness script maturity predicted increased handover accuracy (p < 0.001) and lower cognitive load (p = 0.007). Case complexity did not independently affect either outcome. For handover accuracy, there was no interaction between case complexity and illness script maturity. For cognitive load, there was an interaction effect between illness script maturity and case complexity, indicating that more mature illness scripts reduced cognitive load less in complex cases than in simple cases. CONCLUSIONS: Students with more mature illness scripts performed more accurate handovers and experienced lower cognitive load. For cognitive load, these effects were more pronounced in simple than complex cases. If replicated, these findings suggest that handover curricula and protocols should provide support that varies according to the knowledge of the trainee.

Preparation by mandatory E-modules improves learning of practical skills: a quasi-experimental comparison of skill examination results.

BACKGROUND: Until recently, students at UMC Utrecht Faculty of Medicine prepared for practical skills training sessions by studying recommended literature and making written assignments, which was considered unsatisfactory. Therefore, mandatory e-modules were gradually introduced as substitute for the text based preparation. This study aimed to investigate whether this innovation improved students' performance on the practical skills (OSCE) examination. METHOD: In both the 2012 and 2013 OSCEs, e-modules were available for some skill stations whereas others still had text based preparation. We compared students' performance, both within and between cohorts, for skill stations which had e-module preparation versus skill stations with text based preparation. RESULTS: We found that performance on skill stations for which students had prepared by e-modules was significantly higher than on stations with text based preparation, both within and between cohorts. This improvement cannot be explained by overall differences between the two cohorts. CONCLUSION: Our results show that results of skills training can be improved, by the introduction of e-modules without increasing teacher time. Further research is needed to answer the question whether the improved performance is due to the content of the e-modules of to their obligatory character.

Using script theory to cultivate illness script formation and clinical reasoning in health professions education.

Script theory proposes an explanation for how information is stored in and retrieved from the human mind to influence individuals' interpretation of events in the world. Applied to medicine, script theory focuses on knowledge organization as the foundation of clinical reasoning during patient encounters. According to script theory, medical knowledge is bundled into networks called 'illness scripts' that allow physicians to integrate new incoming information with existing knowledge, recognize patterns and irregularities in symptom complexes, identify similarities and differences between disease states, and make predictions about how diseases are likely to unfold. These knowledge networks become updated and refined through experience and learning. The implications of script theory on medical education are profound. Since clinician-teachers cannot simply transfer their customized collections of illness scripts into the minds of learners, they must create opportunities to help learners develop and fine-tune their own sets of scripts. In this essay, we provide a basic sketch of script theory, outline the role that illness scripts play in guiding reasoning during clinical encounters, and propose strategies for aligning teaching practices in the classroom and the clinical setting with the basic principles of script theory.

Thirty years of illness scripts: Theoretical origins and practical applications.

AIM: This study describes the introduction and spread of the concept of "illness script" in the medical education literature. METHOD: First, I will concisely discuss the development of the "script" concept in the general psychological literature and the results of the studies performed to provide it with the necessary empirical basis. Next, I will sketch how "scripts" entered the medical domain via efforts to develop diagnostic systems in the field of artificial intelligence. Subsequently, I will describe how the illness script concept was elaborated and specified by medical educators and educational researchers. RESULTS AND DISCUSSION: The illness script concept has solid underpinnings and can be used to elucidate aspects of medical expertise development. It can also be used to formulate recommendations for clinical teaching and has yielded a specific test, the Script Concordance Test.
