Tumor board simulation improves interdisciplinary decision-making in medical students.

INTRODUCTION: Training of interdisciplinary clinical reasoning and decision-making skills, essential in daily clinical practice in oncological specialties, are still underrepresented in medical education. Therefore, at LMU University Hospital Munich, we implemented a didactically modified tumor board simulation with experts from five different disciplines (medical oncology, pathology, radiation oncology, radiology, and surgery) presenting patient cases into a one-week course on the basic principles of oncology. In this survey, we examined the self-assessed impact of our course on the interdisciplinary decision-making skills of medical students. METHODS: Between November-December 2023 and January-February 2024, we surveyed two cohorts of medical students in the third year of medical school in our one-week course before and after participating in the tumor board simulation. The objective was to evaluate the self-assessed knowledge in interdisciplinary clinical decision-making, in integrating ethical considerations into clinical reasoning, and in comprehension of various professional viewpoints in interdisciplinary decision-making. Knowledge was assessed using a five-step Likert scale from 1 (no knowledge) to 5 (complete knowledge). RESULTS: The survey was answered by 76 students before and 55 after the simulation, equaling 60-70% of all 100 course participants. Mean knowledge level regarding principles of interdisciplinary clinical decision-making improved significantly in all of the following exemplary aspects: purpose and procedure of tumor boards in clinical practice (from 2.4 ± 1.1 to 4.0 ± 1.0, Spearman's ρ = 0.6, p < 0.001), principles of dealing with ethical challenges in oncology (from 2.4 ± 1.1 to 3.4 ± 1.0, ρ = 0.4, p < 0.001), and principles of shared decision-making in oncology (2.7 ± 1.1 to 3.7 ± 1.0, ρ = 0.4, p < 0.001). Students reported that their skills in clinical decision-making and ability to discuss oncological patient cases from different professional viewpoints improved due to the teaching course. CONCLUSION: By employing our interdisciplinary one-week course and a didactically modified tumor board simulation featuring experts from various oncological disciplines, medical students' comprehension of interdisciplinary clinical decision-making in oncology improved significantly.

Influence of learning strategies and motivation on anatomy test performance of undergraduate medical students.

To learn and comprehend the large amount of information in gross anatomy, undergraduate students must self-regulate their learning to be properly prepared for the exams within the available time. Even though there are many studies on learning strategies and their influence on test results and motivation, the aim of this study is to investigate characteristics of learning strategies in detail and in relation to the anatomy course of first semester students and how their use is related to anatomy test performance. For assessing the learning strategies, we used the short version of the questionnaire "Learning Strategies of University Students" (LIST-K) (Klingsieck, 2018). Further, we investigated potential influences of motivation and resources used during the self-regulated learning process. The participants in this study (N = 108) filled in the above-mentioned questionnaire LIST-K and a written multiple-choice anatomy test. A k-means cluster analysis revealed three groups of students differing in their self-reported use of learning strategies. Students used either (1) predominantly metacognitive and resource-related strategies, (2) predominantly cognitive strategies, or (3) no specific learning strategies at all. We found no significant overall relationships between the use of learning strategies and test performance. A stepwise linear regression identified the use of cognitive learning strategies (ß =.269) as a significant predictor for test performance (R² =.149, p =.003), possibly as these specific learning strategies help with a systematic and effective approach while studying anatomy and retrieving large amount of memorized information. Further, motivation was identified as a negative predictor (ß = -.277), which might be a result of the short time periods students have to study for exams. Overall findings underline the importance of self-regulated learning as a positive predictor for academic performance. By understanding these factors, a more student-centered approach could be adopted by educators to improve medical education and equip students with valuable approaches for their continuous education, even beyond university.

Prevalence of Anxiety and Depression Symptoms among University Teachers in Ethiopia during the COVID-19 Pandemic.

A growing body of evidence suggests an increased prevalence of anxiety and depression among teachers during the COVID-19 pandemic. However, there is little evidence in research documenting the extent of anxiety and depression in the university teacher population and how these relate to feelings of loneliness. This study aims to explore the prevalence of anxiety and depression symptoms among university teachers, identify differences, and further examine the relationships between loneliness and symptoms of anxiety and depression. The study participants included university teachers in the College of Health and Medical Sciences from four purposefully selected public universities who completed a survey questionnaire consisting of items that measured anxiety and depressive symptoms as well as loneliness. The final sample included 148 participants (45 participants [30.4%] located in the center or capital; 125 (83.1%) men; and 90 [62.5%] taught both online and face-to-face). The university teachers' sample mean age = 39.07 had an SD = 7.67. As per the findings of this study, the prevalence of anxiety and depression symptoms was significant (11% and 12.3%) among university teachers in Ethiopia during the COVID-19 pandemic. Also, this study found a significant association between these symptoms and loneliness. Therefore, incorporating relevant strategies to promote mental well-being and targeting individuals who felt lonely were essential for overcoming health-related burdens. Universities should equip teachers with resources to prevent mental health issues and offer need-based counseling services to alleviate them.

Why did I participate in an HIV vaccine study? Experiences of participation in the first phase II HIV vaccine trial in Mozambique: An ancillary study using a mixed-method approach.

Introduction: This study recognized the lack of information regarding recruitment and retention factors associated with implementing HIV vaccine trials from the perspective of de facto participants. It aimed to describe the motives and experiences of 31 young adults who participated in a phase II HIV vaccine clinical trial conducted in Maputo, Mozambique. Methods: This was an ancillary study with a mixed-method approach that employed a convergent design, combining both quantitative and qualitative methodologies. Data collection involved questionnaire surveys, in-depth interviews, and focus group discussions. Participants were assessed before and after learning whether they received the experimental vaccine or placebo. Thematic analysis was used for qualitative data, while descriptive analysis and statistical tests such as Fischer's test and McNemar's exact test were applied to quantitative data. The study also utilized the Health Belief Model to understand the decision-making process of participating in an HIV vaccine study. Results: Most of our participants were young females, single, with limited financial resources. Participants joined the trial with the belief that they had a unique opportunity to help the fight against HIV and contribute to the research for the discovery of an HIV vaccine. Positive experiences related to trial participation include gaining knowledge about HIV and personal health and receiving risk reduction counseling. Participants reported blood collection as a negative experience and that they suffered social harm because of trial participation. Participants felt abandoned after the trial ended. Conclusion: Preventive HIV vaccine trials should integrate a social-behavioral component to assess reasons for participation and refusal in real-time. Providing ongoing personal attention is crucial for young individuals who have committed 1-2 years to trial participation, extending beyond the trial period. Implementing tailored strategies for HIV risk assessment and reduction during and after the trial is essential. Addressing these factors can enhance preventive HIV vaccine trial implementation.

Interaction between overconfidence effects and training formats in nurses' education in hand hygiene.

BACKGROUND: Undergraduate training in hand hygiene is a keystone of infection control. Several studies have shown overconfidence effects in hand hygiene practices, which can impair metacognition. We hypothesized that overconfidence might be prevalent in the early education stages of nursing students and that these effects could be reduced through frequent interactive learning formats, such as learning groups. METHODS: We conducted a multicenter cross-sectional questionnaire with 196 German nursing students, including general, surgical, and anesthetic nursing specializations. RESULTS: Overconfidence was observed in nursing students across all specialties and years of education. The cluster analyses showed three different types of learners: two characterized by overconfidence and one demonstrating justifiable confidence. Furthermore, the moderation analysis indicated that providing feedback and promoting metacognition regarding students' learning achievements could mitigate overplacement, particularly through the frequent implementation of interactive teaching formats. DISCUSSION: Despite some limitations, these findings highlight the prevalence of overconfidence effects in nursing students, the presence of different learning profiles, and the importance of incorporating feedback within interactive learning formats concerning hand hygiene. Accordingly, educators need to be trained and supervised to deliver these learning formats and provide feedback to students effectively.

Radiographical diagnostic competences of dental students using various feedback methods and integrating an artificial intelligence application-A randomized clinical trial.

INTRODUCTION: Radiographic diagnostic competences are a primary focus of dental education. This study assessed two feedback methods to enhance learning outcomes and explored the feasibility of artificial intelligence (AI) to support education. MATERIALS AND METHODS: Fourth-year dental students had access to 16 virtual radiological example cases for 8 weeks. They were randomly assigned to either elaborated feedback (eF) or knowledge of results feedback (KOR) based on expert consensus. Students´ diagnostic competences were tested on bitewing/periapical radiographs for detection of caries, apical periodontitis, accuracy for all radiological findings and image quality. We additionally assessed the accuracy of an AI system (dentalXrai Pro 3.0), where applicable. Data were analysed descriptively and using ROC analysis (accuracy, sensitivity, specificity, AUC). Groups were compared with Welch's t-test. RESULTS: Among 55 students, the eF group by large performed significantly better than the KOR group in detecting enamel caries (accuracy 0.840 ± 0.041, p = .196; sensitivity 0.638 ± 0.204, p = .037; specificity 0.859 ± 0.050, p = .410; ROC AUC 0.748 ± 0.094, p = .020), apical periodontitis (accuracy 0.813 ± 0.095, p = .011; sensitivity 0.476 ± 0.230, p = .003; specificity 0.914 ± 0.108, p = .292; ROC AUC 0.695 ± 0.123, p = .001) and in assessing the image quality of periapical images (p = .031). No significant differences were observed for the other outcomes. The AI showed almost perfect diagnostic performance (enamel caries: accuracy 0.964, sensitivity 0.857, specificity 0.074; dentin caries: accuracy 0.988, sensitivity 0.941, specificity 1.0; overall: accuracy 0.976, sensitivity 0.958, specificity 0.983). CONCLUSION: Elaborated feedback can improve student's radiographic diagnostic competences, particularly in detecting enamel caries and apical periodontitis. Using an AI may constitute an alternative to expert labelling of radiographs.

Development of the entrustable professional activity 'medication reconciliation' for clinical pharmacy.

BACKGROUND: Entrustable professional activities (EPAs) are observable process descriptions of clinical work units. EPAs support learners and tutors in assessment within healthcare settings. For use amongst our pharmacy students as well as pre-registration pharmacists we wanted to develop and validate an EPA for use in a clinical pharmacy setting at LMU University Hospital. METHODS: The development of the clinical pharmacy EPA followed a set pathway. A rapid literature review informed the first draft, an interprofessional consensus group consisting of pharmacists, nurses, and medical doctors refined this draft. The refined version was then validated via online survey utilising clinical pharmacists from Germany. RESULTS: We designed, refined and validated an EPA regarding medication reconciliation for assessment of pharmacy students and trainees within the pharmacy department at LMU University Hospital in Munich. Along with the EPA description an associated checklist to support the entrustment decision was created. For validation an online survey with 27 clinical pharmacists from all over Germany was conducted. Quality testing with the EQual rubric showed a good EPA quality. CONCLUSIONS: We developed the first clinical pharmacy EPA for use in a German context. Medication reconciliation is a suitable EPA candidate as it describes a clinical activity performed by pharmacists in many clinical settings. The newly developed and validated EPA 'Medication Reconciliation' will be used to assess pharmacy students and trainees.

Encouraging medical students to become surgeons? Impact of psychological and surgical factors on career choice at medical school.

Aim: Training decisions are viewed as a problem by the majority of medical students.In the present study we compared sociodemographic and psychological characteristics of students who are interested in surgical training to those who preferred a non-surgical specialty. Furthermore, we examined whether students who wish to be trained as surgeons performed better than their non-surgical counterparts in a course designed to acquire skills in minimally invasive surgery. Method: From October 2020 to January 2021 we performed a cross-sectional survey among 116 medical students prior to their year of practical training at Christian-Albrechts University in Kiel. Based on their intended field of specialization, the students were divided into a non-surgical and a surgical group. Sociodemographic and psychological characteristics such as self-efficacy expectations, resilience and stress perception were evaluated and compared between groups. Simultaneously, we compared their surgical performance in two laparoscopic exercises and their self-assessment as surgeons. Statistical differences between the training groups were determined by the Mann-Whitney U test or Pearson's Chi square test. Results: Ninety-two students participated in the study, of whom 64.1% intended to train in a non-surgical specialty and 35.9% in a surgical specialty. Students who wished to be trained as surgeons had higher general self-efficacy expectations (p<0.001) and greater resilience (p=0.009). However, on comparison they had a lower stress level (p=0.047). The inter-group comparison of training results and self-assessment as surgeons revealed no unequivocal differences in surgical performance. Conclusion: Interest in surgical specialties is correlated, among other factors, with the strength of psychological skills such as general self-efficacy expectations, resilience and stress perception. Early attention to these psychological resources in academic training might assist medical students in future career choices.

Lost in translation: Unveiling medical students' untold errors of medical history documentation.

OBJECTIVE: The accurate documentation of a medical history interview is an important goal in medical education. As students' documentation of medical history interviews is mostly decentralised on the wards, a systematic assessment of documentation quality is missing. We therefore evaluated the extent of details missed in students' medical history reports in a standardised setting. METHODS: In this prospective, observational study, 123 of 380 students (32.4%) participated in an Objective Structured Clinical Examination (OSCE) regarding history taking and documentation. Based on the interviews and nine deductively selected main categories, a categorical system was established using a summarising qualitative content analysis. The items in the transcripts (defined as ground truth) and in students' reports were labelled and assigned to the correct subcategory. The ground truth and students' reports were compared to quantify students' documentation completeness. RESULTS: Next to the nine deductively selected main categories, 61 subcategories were defined. A total of 8943 items were labelled in the 123 interview transcripts (ground truth), compared with 5870 items labelled in students' reports (65.6% completeness of students' reports compared with ground truth). The main category personal details overlapped with 94.2% between students' report and ground truth in contrast to the main category with the highest discrepancy, allergy, with 41.1% overlap. Pertinent negative items and non-numerical quantifications were often missed. CONCLUSIONS: Medical students show incomplete documentation of medical history interviews. Therefore, accurate documentation should be taught as an important goal in medical education.

Insights into diagnostic errors in endocrinology: a prospective, case-based, international study.

BACKGROUND: Diagnostic errors in internal medicine are common. While cognitive errors have previously been identified to be the most common contributor to errors, very little is known about errors in specific fields of internal medicine such as endocrinology. This prospective, multicenter study focused on better understanding the causes of diagnostic errors made by general practitioners and internal specialists in the area of endocrinology. METHODS: From August 2019 until January 2020, 24 physicians completed five endocrine cases on an online platform that simulated the diagnostic process. After each case, the participants had to state and explain why they chose their assumed diagnosis. The data gathering process as well as the participants' explanations were quantitatively and qualitatively analyzed to determine the causes of the errors. The diagnostic processes in correctly and incorrectly solved cases were compared. RESULTS: Seven different causes of diagnostic error were identified, the most frequent being misidentification (mistaking one diagnosis with a related one or with more frequent and similar diseases) in 23% of the cases. Other causes were faulty context generation (21%) and premature closure (17%). The diagnostic confidence did not differ between correctly and incorrectly solved cases (median 8 out of 10, p = 0.24). However, in incorrectly solved cases, physicians spent less time on the technical findings (such as lab results, imaging) (median 250 s versus 199 s, p < 0.049). CONCLUSIONS: The causes for errors in endocrine case scenarios are similar to the causes in other fields of internal medicine. Spending more time on technical findings might prevent misdiagnoses in everyday clinical practice.

The role of research competence as an influencing factor for the careers of young academics. Findings and implications from studies on doctorates in medicine and life sciences in Germany.

Background: When viewed internationally, Germany boasts a high rate of doctoral candidates. Fields such as medicine and life sciences have a notably high proportion of doctoral students, a trend rooted in historical factors. Despite this, comprehensive empirical studies concerning the doctoral phase and early-career researchers, especially in relation to the rise of structured doctoral programmes, have only recently gained traction. Methods: We present findings from a project investigating young scientists in medicine and life sciences. Postdoctoral graduates from these disciplines were examined both quantitatively and qualitatively within the E-Prom projects, emphasizing the primary domain of research. Results: Our analysis indicates some benefits of structured doctoral programmes over traditional individual doctorates. However, the disparities between these doctoral approaches are less pronounced than anticipated. We also identified discrepancies between the programme descriptions and their actual execution. Integration into the scientific community and research-related self-efficacy are potential indicators of publication output and inclination towards a scientific career. Physicians exhibited lower research-related self-efficacy and a lesser tendency towards a scientific career than biologists. Notably, we found gender disparities disadvantaging female graduates, with these disparities being more marked in medicine. Conclusions: There is evidence to suggest that official representations of structured doctoral programmes do not always align with their practical applications, limiting their potential effectiveness. Therefore, resources should be allocated to ensure the consistent execution of these programmes. Given the empirical evidence supporting the benefits of community integration for junior researchers, efforts should be made to facilitate their networking. Additionally, our findings emphasize the necessity of providing enhanced support for young female scientists.

German first-year medical students' expectations of their professional life - concerns and hopes: A project report.

Aim: Expectations among medical students towards their future professional life are affected by intrinsic and extrinsic factors which may change during years of medical school. The aim of this study is to gain further insight into students' expectations of their professional life at the beginning of medical school. Findings regarding contextual influences can be used to improve curricula and student guidance. Methods: The project report based on an online survey among three cohorts of first year medical students at the LMU. The questionnaire consisted of six open-ended questions which addressed the student's motivation, expectations, anticipations and concerns of their professional life. Questions were also asked about presumed personal development and influence on private life. An inductive coding was used in this qualitative content analysis. Results: Written responses from 591 participants were coded, categorized and summarized into four main themes: personal life, work, science, personal issue. Despite coming from different cohorts, the occurrence of the main themes showed the same trend in all student groups. Students are worried most about the work-life-balance, and they expect it to be a difficult issue. But many of our first-year students are optimistic that they will be able to establish a good work-life-balance or that the working conditions will have changed to a manageable workload at the time they will enter their first jobs. The majority of our students expect to become more self-confident with enhanced empathy and team-working ability and more patient and stress-resistant in daily challenges. Conclusion: The medical students emphasize the gender-neutral desire for work-life balance. So, they expect improved working conditions for the future - an ongoing challenge for the health care system.

Characteristics and quality assessment of online mentoring profile texts in academic medical mentoring.

BACKGROUND: Mentoring is important for a successful career in academic medicine. In online matching processes, profile texts are decisive for the mentor-selection. We aimed to qualitatively characterize mentoring-profile-texts, identify differences in form and content and thus elements that promote selection. METHODS: In a mixed method study first, quality of texts in 150 selected mentoring profiles was evaluated (10-point Likert scale; 1 = insufficient to 10 = very good). Second, based on a thematic and content analysis approach of profile texts, categories and subcategories were defined. We compared the presence of the assigned categories between the 25% highest ranked profiles with the 25% lowest ranked ones. Finally, additional predefined categories (hot topics) were labelled on the selected texts and their impact on student evaluation was statistically examined. RESULTS: Students rated the quality of texts with a mean of 5.89 ± 1.45. 5 main thematic categories, 21 categories and a total of 74 subcategories were identified. Ten subcategories were significantly associated with high- and four with low-rated profiles. The presence of three or more hot topics in texts significantly correlated with a positive evaluation. CONCLUSION: The introduced classification system helps to understand how mentoring profile texts are composed and which aspects are important for choosing a suited mentor.

FINCA - a conceptual framework to improve interprofessional collaboration in health education and care.

The health care system in Germany and in many other countries is facing fundamental challenges due to demographic change, which require new integrated care concepts and a revision of the collaboration between health care professions in everyday clinical practice. Internationally, several competency framework models have been proposed, but a framework that explicitly conceptualizes collaborative activities to improve interprofessional problem-solving competency in health care is still missing. Such a framework should define contextual, person-related, process-related, and outcome-related variables relevant to interprofessional problem solving in health care. Against this background, we present a conceptual framework to improve interprofessional collaboration in health education and care (FINCA) developed with scientific consideration of empirical data and various theoretical references. FINCA reflects an interprofessional learning and interaction process involving two persons from different health care professions and with different individual learning prerequisites. These two initially identify a problem that is likely to require interprofessional collaboration at some point. FINCA acknowledges the context of interprofessional learning, teaching, and working as well as its action-modifying context factors. We follow the reasoning that individual learning prerequisites interact with the teaching context during learning activities. At the heart of FINCA are observable collaborative activities (information sharing and grounding; negotiating; regulating; executing interprofessional activities; maintaining communication) that can be used to assess individuals' cognitive and social skills. Eventually, the framework envisages an assessment of the outcomes of interprofessional education and collaboration. The proposed conceptual framework provides the basis for analysis and empirical testing of the components and variables it describes and their interactions across studies, educational interventions, and action-modifying contexts. FINCA further provides the basis for fostering the teaching and learning of interprofessional problem-solving skills in various health care settings. It can support faculty and curriculum developers to systematize the implementation and improvement of interprofessional teaching and learning opportunities. From a practical perspective, FINCA can help to better align curricula for different health professions in the future. In principle, we also see potential for transferability of the framework to other areas where different professions collaborate.

Principles of oncology taught in a one-week course.

BACKGROUND: Growing challenges in oncology require evolving educational methods and content. International efforts to reform oncology education are underway. Hands-on, interdisciplinary, and compact course formats have shown great effectiveness in the education of medical students. Our aim was to establish a new interdisciplinary one-week course on the principles of oncology using state-of-the-art teaching methods. METHODS: In an initial survey, medical students of LMU Munich were questioned about their current level of knowledge on the principles of oncology. In a second two-stage survey, the increase in knowledge resulting from our recently established interdisciplinary one-week course was determined. RESULTS: The medical students' knowledge of clinically important oncological topics, such as the diagnostic workup and interdisciplinary treatment options, showed a need for improvement. Knowledge of the major oncological entities was also in an expandable state. By attending the one-week course on the principles of oncology, students improved their expertise in all areas of the clinical workup in oncology and had the opportunity to close previous knowledge gaps. In addition, students were able to gain more in-depth clinical knowledge on the most common oncological entities. CONCLUSION: The interdisciplinary one-week course on the principles of oncology proved to be an effective teaching method to expand the knowledge of the future physicians to an appropriate level. With its innovative and interdisciplinary approach, the one-week course could be used as a showcase project for the ongoing development of medical education in Germany.

Objective and subjective consequences of pandemic-related study program changes for the perception of the practical year - a comparison of medical students in Germany with and without a second national board examination.

Background: Due to SARS-CoV-2, the Bavarian Ministry of Health decided in April 2020 to postpone the second national board examination in human medicine and to bring forward the start of the practical year (in German: Praktisches Jahr, further abbreviated with PJ) from May to April 2020. The different tertial times made it necessary for affected students to reorganise the PJ and rendered the preparation for the national board examination that had already taken place obsolete. As a result, students had to prepare for it again after the PJ and take it together with the third national board examination. Research question: How do students affected by the early PJ differ in their perception of the practical year and in their psychological well-being from the comparison groups with a regular PJ schedule? Methodology: The study is based on quantitative data from the Dean of Studies Office of the Medical Faculty of Ludwig-Maximilians-Universität München (LMU) and an online survey. The sample consists of LMU students who started the early PJ in April 2020 (n=86) and two comparison groups: The cohort of LMU students who started their PJ regularly in May 2019 (n=50), and students from other German universities who started their PJ regularly in May 2020 (n=98) and took the second national board examination in human medicine in spring 2020. Results: For students affected by the early PJ, there were measurable negative effects on the choice of training institutions, the quality of the PJ content, preparation for the national board examinations, and career planning. Compared to regular students from other federal states, affected students reported higher psychological stress, with comparable resilience. Conclusion: It can be assumed that the insights gained apply to the entirety of medical students in the affected federal states of Bavaria and Baden-Württemberg. As a conclusion, we make the recommendation to include the position of the students in decisions of great consequence.

Bayesian versus diagnostic information in physician-patient communication: Effects of direction of statistical information and presentation of visualization.

BACKGROUND: Communicating well with patients is a competence central to everyday clinical practice, and communicating statistical information, especially in Bayesian reasoning tasks, can be challenging. In Bayesian reasoning tasks, information can be communicated in two different ways (which we call directions of information): The direction of Bayesian information (e.g., proportion of people tested positive among those with the disease) and the direction of diagnostic information (e.g., the proportion of people having the disease among those tested positive). The purpose of this study was to analyze the impact of both the direction of the information presented and whether a visualization (frequency net) is presented with it on patient's ability to quantify a positive predictive value. MATERIAL AND METHODS: 109 participants completed four different medical cases (2⨯2⨯4 design) that were presented in a video; a physician communicated frequencies using different directions of information (Bayesian information vs. diagnostic information). In half of the cases for each direction, participants were given a frequency net. After watching the video, participants stated a positive predictive value. Accuracy and speed of response were analyzed. RESULTS: Communicating with Bayesian information led to participant performance of only 10% (without frequency net) and 37% (with frequency net) accuracy. The tasks communicated with diagnostic information but without a frequency net were correctly solved by 72% of participants, but accuracy rate decreased to 61% when participants were given a frequency net. Participants with correct responses in the Bayesian information version without visualization took longest to complete the tasks (median of 106 seconds; median of 13.5, 14.0, and 14.5 seconds in other versions). DISCUSSION: Communicating with diagnostic information rather than Bayesian information helps patients to understand specific information better and more quickly. Patients' understanding of the relevance of test results is strongly dependent on the way the information is presented.

Planetary health as a main topic for the qualification in digital teaching - a project report.

Aim: To do justice to the need for planetary health in medical education, these are the aims of the online elective course "Planetary Health in Medical Education" (ME elective):1. Enable students to plan and realize their own course sessions on planetary health;2. Encourage communication among university medical faculties regarding planetary health in medical education;3. Reinforce competency in digital teaching and amplify the expert role as multiplicator among students pursuing a Master's degree in Medicinal Education (MME). Method: The development of the ME elective followed Kern's six-step approach to curriculum development by means of cooperation between the German Medical Students' Association (Bundesvertretung der Medizinstudierenden in Deutschland, abbreviated as bvmd), and the MME study program. Based on general and specific needs analyses, core learning objectives regarding planetary health, medical education and digital education were identified in the National Catalogue of Learning Objectives in Undergraduate Medical Education (NKLM) and the MME study program and relevant teaching methods were selected. Results: The ME elective, consisting of two contact hours per week per semester, was established at 13 medical schools as a four-phase course:1. Introduction to medical education using examples from planetary health;2. Lesson planning on a topic in planetary health under the supervision of MME students;3. Course sessions held by the undergraduate students; and4. Networking with the MME study program through participation in digital courses on planetary health and the pilot OSCE on planetary health.A total of 24 students attended the pilot in the 2022 summer semester. Conclusion: The topic of planetary health combines interests that span many subjects and semester levels. As a collaborative, interdisciplinary and interprofessional subject, it lends itself to training students in a trans-institutional elective course to become multiplicators.

Diagnosing virtual patients: the interplay between knowledge and diagnostic activities.

Clinical reasoning theories agree that knowledge and the diagnostic process are associated with diagnostic success. However, the exact contributions of these components of clinical reasoning to diagnostic success remain unclear. This is particularly the case when operationalizing the diagnostic process with diagnostic activities (i.e., teachable practices that generate knowledge). Therefore, we conducted a study investigating to what extent knowledge and diagnostic activities uniquely explain variance in diagnostic success with virtual patients among medical students. The sample consisted of N = 106 medical students in their third to fifth year of university studies in Germany (6-years curriculum). Participants completed professional knowledge tests before diagnosing virtual patients. Diagnostic success with the virtual patients was assessed with diagnostic accuracy as well as a comprehensive diagnostic score to answer the call for more extensive measurement of clinical reasoning outcomes. The three diagnostic activities hypothesis generation, evidence generation, and evidence evaluation were tracked. Professional knowledge predicted performance in terms of the comprehensive diagnostic score and displayed a small association with diagnostic accuracy. Diagnostic activities predicted comprehensive diagnostic score and diagnostic accuracy. Hierarchical regressions showed that the diagnostic activities made a unique contribution to diagnostic success, even when knowledge was taken into account. Our results support the argument that the diagnostic process is more than an embodiment of knowledge and explains variance in diagnostic success over and above knowledge. We discuss possible mechanisms explaining this finding.
