The patient as text: a challenge for problem-based learning

Humanising case-based learning

PURPOSE OF THE ARTICLE

Medical undergraduates at St George's, University of London (SGUL) study a weekly clinical case during their clinical science years. Audit of the human stories demonstrated lack of diversity, mono-professionalism, and objectification of some patients. A collaborative partnership with staff, student and patient representation implemented curriculum change, including an inclusive case-writing initiative. We explored whether the reformed written cases supported the development of positive attitudes by sampling perceptions of the cases amongst students.

METHODS

Sixteen semi-structured interviews were conducted (Feb-November 2022) with first year medical students. We applied an interpretative phenomenological analysis approach. Verbatim transcripts were coded and analysed to elucidate themes.

RESULTS

Four themes were identified: (i) effective learning, (ii) clinical authenticity, (iii) authentic human stories, and (iv) opportunity for rehearsing the role of a doctor. Students perceived the cases as an effective, contextual learning method, with a high degree of clinical authenticity, allowing mentalisation of doctor attitudes and behaviours in relation to patient-centredness, multidisciplinary team working and diversity.

CONCLUSION

The results suggest the reformed cases created positive attitudinal change amongst students and supported transition to clinical roles. Memorable human stories had the greatest impact. Dynamic, inclusive, and collaborative case writing initiatives which integrate realism, diversity and multi-professionalism may help to foster positive experiences in students undertaking CBL sessions.

A gender biased hidden curriculum of clinical vignettes in undergraduate medical training

OBJECTIVES

Medical education relies extensively on clinical vignettes, yet little attention has been given to what hidden curriculum they might convey. Our research aimed to identify whether the clinical vignettes used in pre-graduate medical education transmit gender stereotypes or gender biases.

METHODS

We conducted a mixed quantitative and qualitative analysis of gender-related characteristics currently existing in clinical vignettes used for pre-graduate teaching and evaluation at the Geneva Faculty of Medicine.

RESULTS

2359 vignettes were identified, of which 955 met inclusion criteria. Patients' professions and family caregiver roles showed a strongly gendered distribution, as did the healthcare professions where male physicians and female nurses were the norm. Qualitative results identified widespread stereotyped gender roles and gender expression.

CONCLUSION

Our study reveals that the clinical vignettes used in education and evaluation materials in pre-graduate medical education in Geneva convey a gender-biased hidden curriculum, which could negatively impact patient care and undermine equal opportunity for men and women.

PRACTICE IMPLICATIONS

Active revision of the content and the form of clinical vignettes used in undergraduate medical education is needed using a gender lens. Based on rare gender neutral or gender transformative examples from our study, we propose guidelines for writing non-gender-biased vignettes.

Case-based learning interventions for undergraduate nursing students in a theoretical course: A review of design, implementation, and outcomes

BACKGROUND

Case-based learning (CBL) is a contextualized learning and teaching method that can facilitate active and reflective learning to develop critical thinking and problem-solving skills. However, nursing educators have some difficulty in creating a CBL environment that matches the diverse professional nursing curriculum and students' needs, including developing relevant cases and appropriate CBL implementation processes.

OBJECTIVE

To summarize the case design, implementation process, and their relationship with CBL effectiveness.

METHODS

Electronic databases of PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure (CNKI) and Wanfang Data (a Chinese database) were searched from inception until January 2022. Study quality was assessed using the Mixed Methods Appraisal Tool. A qualitative synthesis was then conducted to summarize the study findings.

RESULTS

The systematic mixed studies review included twenty-one quantitative studies, five qualitative studies and two mixed methods studies. The case design and implementation process were indispensable parts of each study, but the application process of CBL in each study was slightly different, basically including case design, preparation, small-group interaction and exploration, collaborative efforts, teacher summary, assignment and teacher feedback. There were three themes in this review that indicate the effect of CBL on students, namely, knowledge, competence and attitude.

CONCLUSION

The present review analyzes the available literature and suggests that there is no common format for the case design and CBL implementation process, but demonstrates that they are an indispensable part of each study. This review provides conceptual procedures for nurse educators to design and implement CBL in nursing theoretical courses to improve the effectiveness of CBL.

Evaluation of Virtual Reality High-Fidelity Adult Mannequin-based Simulation of Real-Life Clinical Scenarios in Teaching Clinical Pharmacology to Medical Students

Background

Presently, competency-based medical (CBME) curriculum challenges the medical educators to provide continuing education with new approaches to make learning more stimulating, motivating, and entertaining, fostering excellence in clinical practice. To address these issues, educators have advocated the use of virtual reality and mannequins to teach clinical pharmacology.

Aims and Objectives

To study the effect, perception, and feedback of virtual reality high-fidelity adult mannequin-based (VHFM) simulation of real-life clinical scenarios over conventional tutorials in teaching clinical pharmacology to medical students.

Material and Methods

An interventional study was designed for 2nd year MBBS students for a period of 6 months. The enrolled students were randomly assigned to the test group (VHFM) or control group (tutorials). The CAE Healthcare Ltd. maestro, high-fidelity prehospital mannequin (APOLLO) was used in the test group. Three sessions consisting of six different cases were discussed, and multiple-choice questions (MCQs)-based pre-test, post–test, and retest after a month were conducted in both groups and compared. The perception and feedback of faculty and students were obtained by using a modified and revalidated questionnaire.

Results

The test group outperformed the control group ( p <.001) in all sessions based on pre-test, post-test, and retest scores, and within-group comparisons revealed significant improvements in both groups. Students’ perceptions and feedback regarding VHFM were more enthusiastic and promising than in the tutorial group.

Conclusions

VHFM is student-centered, provides an active learning environment, and aids in skill development. We strongly suggest VHFM-based learning as a complement to traditional teaching strategies in pharmacology, especially for teaching clinical reasoning to medical students.

Case-Informed Learning in Medical Education: A Call for Ontological Fidelity

Case-informed learning is an umbrella term we use to classify pedagogical approaches that use text-based cases for learning. Examples include Problem-Based, Case-Based, and Team-Based approaches, amongst others. We contend that the cases at the heart of case-informed learning are philosophical artefacts that reveal traditional positivist orientations of medical education and medicine, more broadly, through their centering scientific knowledge and objective fact. This positivist orientation, however, leads to an absence of the human experience of medicine in most cases. One of the rationales for using cases is that they allow for learning in context, representing aspects of real-life medical practice in controlled environments. Cases are, therefore, a form of simulation. Yet issues of fidelity, widely discussed in the broader simulation literature, have yet to enter discussions of case-informed learning. We propose the concept of ontological fidelity as a way to approach ontological questions (i.e., questions regarding what we assume to be real), so that they might centre narrative and experiential elements of medicine. Ontological fidelity can help medical educators grapple with what information should be included in a case by encouraging an exploration of the philosophical questions: What is real? Which (and whose) reality do we want to simulate through cases? What are the essential elements of a case that make it feel real? What is the clinical story we want to reproduce in case format? In this Eye-Opener, we explore what it would mean to create cases from a position of ontological fidelity and provide suggestions for how to do this in everyday medical education.

Mapping health, social and health system issues and applying a social accountability inventory to a problem based learning medical curriculum

Social accountability is a powerful concept. It is applied to medical education to encourage future doctors to take action to address health inequalities and overlooked health needs of disadvantaged populations. Problem-based learning (PBL) provides an ideal setting to teach medical students about these topics. The objective of this study is to explore how well the components of social accountability are covered in a pre-clinical PBL medical curriculum and to determine the usefulness of an adapted validated social accountability framework. We identified Irish health needs and social issues through a literature review. The retrieved documents were aligned to four values (relevance, equity, cost-effectiveness and quality) from a validated social accountability inventory, to generate a map of social accountability values present in the Irish health system and population. We then used the adapted validated social accountability inventory to evaluate the content of the PBL medical curriculum at an Irish medical school. We identified 45 documents, which upon analysis lead to the identification of health and social issues related to social accountability. 66 pre-clinical PBL cases included demographic, health and psychosocial issues similar to the local population. Analysing along the four social accountability values, the PBL cases demonstrated room for improvement in the equity and relevance domains. Topics for expansion are Traveller health, LGBTI health, alcohol use, climate change and more. Medical educators can use the paper as an example of how to apply this methodology to evaluate PBL cases. Adapting and applying a validated framework is a useful pedagogical exercise to understand established societal values related to social accountability to inform a medical curriculum. We identified opportunities to improve the PBL cases to depict emerging global and social issues.

Race, ethnicity, and gender representation in clinical case vignettes: a 20-year comparison between two institutions

BACKGROUND

The medical case vignette has long been used in medical student education and frequently includes demographic variables such as race, ethnicity and gender. However, inclusion of demographic variables without context may reinforce assumptions and biases. Yet, the absence of race, sexual orientation, and social determinants of health may reinforce a hidden curriculum that reflects cultural blindness. This replication study compared proportions of race, ethnicity, and gender with University of Minnesota (UMN) findings. This study sought to determine if there has been progress in the representation of demographic characteristics in case vignettes.

METHODS

University of North Carolina (UNC) case vignettes from 2015-2016 were analyzed and compared to UMN case vignettes from 1996-1998. Data included mentions of race, ethnicity, gender and social determinants of health.

RESULTS

In the 278 UNC vignettes, white race was noted in 19.7% of cases, black race was in 7.9% cases, and 76.6% of cases were unspecified. In the 983 UMN vignettes, white race was recorded in 2.85% cases, and black race in 0.41% cases. The institutions were significantly different in the proportion of their cases depicting race (0.20; 95% CI (0.15, 0.25)). Males were represented in the majority of vignettes.

DISCUSSION

Comparing case vignettes results from two medical schools suggests that reporting explicit demographic diversity was not significantly different. The findings illustrate that sex was the demographic characteristic consistently described, where males were over-represented. Based on these findings, greater cultural diversity as it intersects with social determinants of health is needed in medical student education.

The effect of case nodes in problem-based learning on the length and quality of discussion: a 2x2 factorial study

BACKGROUND

Problem-based learning (PBL) relies heavily on case structure for their success. To make more meaningful cases, faculty introduced a "case node" that requires students to make a group decision on the action they will take at a given point in the case. The purpose of this study was to determine whether case nodes enhance PBL discussions.

METHODS

Two PBL cases were designed with and without a node. In 2011, 2012, and 2015, first-year medical students were assigned one PBL case with a node and one without a node. In total, 26 groups processed cases with a node while 27 groups processed the same cases without the node. All sessions were audio recorded and analyzed to determine the length and quality of discussions.

RESULTS

Groups with a node, regardless of case (M = 25.62, SD = 12.25) spent significantly more time in discussion on the node topic than those without a node (M = 16.54, SD = 10.33, p=.005, d = .80). Groups with a node, regardless of case (M = 14.38, SD = 8.04) expressed an opinion significantly more frequently than those without a node (M = 6.07, SD = 5.80, p < .001, d = 1.19).

CONCLUSIONS

Case nodes increased both the length and depth of discussion on a topic and may be an effective way to enhance case-based instruction.

Using interviews and observations in clinical practice to enhance authenticity in virtual patients for interprofessional education

BACKGROUND

Interprofessional collaboration is increasingly important in healthcare, but interprofessional education (IPE) faces challenges, such as different study programmes with varied schedules and campuses. These challenges can be met, in part, by using web-based virtual patients (VPs) as a tool in IPE. However, demands for relevant patient presentations and clinical practice increase when VPs are used by students from different programmes. The aim of this study was to improve the presentation of professional perspectives regarding nurses and physicians and their collaboration in order to increase the clinical authenticity of existing VPs.

METHODS

Clinical observations were conducted to gain familiarity with the context. Semi-structured interviews were performed with individual nurses and physicians with experience of patients with leg ulcers. The interviews were recorded, transcribed and analysed using thematic analysis.

RESULTS

The clinical observations exposed a lack of interprofessional collaboration in practice with regard to patients with leg ulcers. The interview analysis resulted in two themes: Clinical care and Organizational structure. The theme Clinical care included nursing with a holistic approach to the patient and awareness of the patient's well-being, including nutrition and home situation. The theme Organizational structure revealed a lack of teamwork in primary care. The interviewees stressed learning together and sharing responsibility, and they emphasised the importance of implementing interprofessional learning in the education of nurses and physicians in order to stimulate future teamwork. The VP should offer a broad medical history so that healthcare students are made aware of how a disease can affect the patient's social situation, and thereby illustrate the importance of interprofessional collaboration. The information should also be comprehensive and clear, leading to a diagnosis, so the student can gain clinical knowledge and build a foundation for discussion of treatment.

CONCLUSIONS

Interviews and observations in clinical practice can be used to enhance authenticity in VPs for interprofessional learning. A thorough look at authentic clinical environments can enrich and improve educational settings using VPs, and it can highlight the challenges students can encounter in clinical care of the patient and in an organisation with regard to interprofessional collaboration.

Pharmacy Students' Perceptions and Performance on the Use of an Online Virtual Experience Tool for Practicing Objective Structured Clinical Examinations

Objective. To examine pharmacy students' performance on and perceptions regarding the use of an interactive online tool for practicing to take objective structured clinical examinations (OSCEs).Methods. The Monash OSCE Virtual Experience (MOVE), an online module consisting of 20 pharmacy case scenarios with virtual patients, was piloted with final-year pharmacy students at Monash University campuses in Australia and Malaysia. A mixed methods approach that included reviewing user attempts and comparing grades, collecting student-administered questionnaires, and holding focus groups was used to examine students' perception and performance.Results. More than 99% of all students attempted at least one online case scenario in preparation for their final in-person OSCE, and 81% attempted all 20 scenarios two or more times. Ninety percent of students at the Malaysia campus and 70% of students at the Australia campus reported that MOVE was a helpful study tool for their OSCE preparation. However, a raw comparison of user attempts and OSCE grades did not find a direct correlation between online module attempts and assessment grades. Self-administered questionnaire and focus group results indicated that MOVE prepared students for targeted and time-restricted history-taking and problem-solving skills. Overall, students perceived MOVE to be a useful learning tool and a less overwhelming learning experience than were face-to-face sessions. Nevertheless, students still preferred face-to-face OSCE practice with simulated patients over online practice with virtual patients.Conclusion. The Monash OSCE Virtual Experience was perceived by our students as a flexible and useful online learning aid in preparing for their final-year OSCE However, there was no direct correlation between online practice attempts and students' exam grades.

Evaluating the effectiveness of video cases to improve patient-centeredness in psychiatry: a quasi-experimental study

OBJECTIVES

To evaluate the effectiveness of including interactive video-based patient cases in preparatory lectures on medical students' patient-centredness and attitudes towards psychiatry.

METHODS

This study was designed as a quasi-experimental intervention study. A preparatory lecture on diagnostic interviewing was given to 204 fourth-year medical students before a 4-week psychiatry clerkship. The students were divided into two groups. One group (n=102) received a preparatory lecture including an interactive video case portraying a doctor performing a diagnostic interview with a simulated patient (intervention group). The other group (n=102) received a conventional preparatory lecture using text-based instructional material (control group). We conducted a paired sample t-test to compare the students' confidence in exhibiting patient-centred communication and their attitudes towards psychiatry before receiving the preparatory lecture and after having completed a minimum of three weeks of clerkship training.

RESULTS

A total of 102 students, 51 in each group, completed a questionnaire at both measurement points. In the intervention group, we found a statistically significantly difference for the students' patient-centredness before (M=69.4, SD=10.0) and after (M=73.8, SD=8.6) the intervention t(97)=2.38, p= 0.02, but no changes in attitudes t(98) =1.07, p=0.28. In the control group, we found no changes in patient-centredness or attitudes.

CONCLUSIONS

Video cases in preparatory lectures appear to be better than text-based material at improving students' patient-centredness in psychiatry. However, neither video cases nor text-based material seem to influence the students' attitudes.

The role of subject presence type on student motivation in a PBL learning environment

Students have been observed as underprepared or skipping steps during the problem-based learning (PBL) process due to fatigue or low motivation, potentially creating a barrier for effective learning. One way to explore resolving this issue is to consider whether variables of problem scenario design can be altered to optimize motivation. This mixed method study considered the impact of presentation modality of the PBL problem subject (i.e., the key character involved in the problem) on student motivation within the context of Speech and Voice Science curricula for forty-six undergraduate students at a midwestern, US university. The frequency of verbal and non-verbal engagement behaviors was monitored during four consecutive PBL problems. The problems were designed to provide increasing levels of social presence and used varied case presentation modalities (e.g., paper, audio-visual, face to face). Although the frequency of engagement behaviors declined during the study and fatigue appeared to play a role, most students identified problems with combination of higher subject presence (i.e., audio-visual, face-to-face) and challenging content as motivating. Students were able to develop a sense of ownership and responsibility for their problem-solving efforts with a problem designed with direct interaction (i.e., face to face) with the problem subject. This study sheds light on the impact of affective problem features (e.g., emotion, personal psychological connection) on students' motivation in the presence of fatigue, which is often undervalued during the design of PBL modules.

Virtual Patient Simulations in Health Professions Education: Systematic Review and Meta-Analysis by the Digital Health Education Collaboration

Background

Virtual patients are interactive digital simulations of clinical scenarios for the purpose of health professions education. There is no current collated evidence on the effectiveness of this form of education.

Objective

The goal of this study was to evaluate the effectiveness of virtual patients compared with traditional education, blended with traditional education, compared with other types of digital education, and design variants of virtual patients in health professions education. The outcomes of interest were knowledge, skills, attitudes, and satisfaction.

Methods

We performed a systematic review on the effectiveness of virtual patient simulations in pre- and postregistration health professions education following Cochrane methodology. We searched 7 databases from the year 1990 up to September 2018. No language restrictions were applied. We included randomized controlled trials and cluster randomized trials. We independently selected studies, extracted data, and assessed risk of bias and then compared the information in pairs. We contacted study authors for additional information if necessary. All pooled analyses were based on random-effects models.

Results

A total of 51 trials involving 4696 participants met our inclusion criteria. Furthermore, 25 studies compared virtual patients with traditional education, 11 studies investigated virtual patients as blended learning, 5 studies compared virtual patients with different forms of digital education, and 10 studies compared different design variants. The pooled analysis of studies comparing the effect of virtual patients to traditional education showed similar results for knowledge (standardized mean difference [SMD]=0.11, 95% CI −0.17 to 0.39, I²=74%, n=927) and favored virtual patients for skills (SMD=0.90, 95% CI 0.49 to 1.32, I²=88%, n=897). Studies measuring attitudes and satisfaction predominantly used surveys with item-by-item comparison. Trials comparing virtual patients with different forms of digital education and design variants were not numerous enough to give clear recommendations. Several methodological limitations in the included studies and heterogeneity contributed to a generally low quality of evidence.

Conclusions

Low to modest and mixed evidence suggests that when compared with traditional education, virtual patients can more effectively improve skills, and at least as effectively improve knowledge. The skills that improved were clinical reasoning, procedural skills, and a mix of procedural and team skills. We found evidence of effectiveness in both high-income and low- and middle-income countries, demonstrating the global applicability of virtual patients. Further research should explore the utility of different design variants of virtual patients.

Students' Learning Experiences from Didactic Teaching Sessions Including Patient Case Examples as Either Text or Video: A Qualitative Study

OBJECTIVES

The aim of this study was to explore medical students' learning experiences from the didactic teaching formats using either text-based patient cases or video-based patient cases with similar content. The authors explored how the two different patient case formats influenced students' perceptions of psychiatric patients and students' reflections on meeting and communicating with psychiatric patients.

METHODS

The authors conducted group interviews with 30 medical students who volunteered to participate in interviews and applied inductive thematic content analysis to the transcribed interviews.

RESULTS

Students taught with text-based patient cases emphasized excitement and drama towards the personal clinical narratives presented by the teachers during the course, but never referred to the patient cases. Authority and boundary setting were regarded as important in managing patients. Students taught with video-based patient cases, in contrast, often referred to the patient cases when highlighting new insights, including the importance of patient perspectives when communicating with patients.

CONCLUSION

The format of patient cases included in teaching may have a substantial impact on students' patient-centeredness. Video-based patient cases are probably more effective than text-based patient cases in fostering patient-centered perspectives in medical students. Teachers sharing stories from their own clinical experiences stimulates both engagement and excitement, but may also provoke unintended stigma and influence an authoritative approach in medical students towards managing patients in clinical psychiatry.

Do virtual patients prepare medical students for the real world? Development and application of a framework to compare a virtual patient collection with population data

BACKGROUND

An important aspect of virtual patients (VPs), which are interactive computer-based patient scenarios, is authenticity. This includes design aspects, but also how a VP collection represents a patient population and how a patient is presented in a VP scenario. Therefore, our aim was to analyze VP scenarios integrated into the combined internal medicine and surgery curriculum at the University of Munich (LMU) and compare the results with data from the population in Germany.

METHOD

We developed a coding framework with four main categories: patient data, patient representation, diagnoses, and setting. Based on the framework we analyzed 66 VP and compared the results with data from the German healthcare system.

RESULTS

Especially in the categories of patient data and patient representation, the VPs presented an unrealistic image of the real world; topics such as unemployment, disability, or migration background were almost non-existent. The diagnoses of the VPs and the onset of diseases were comparable with the healthcare data.

CONCLUSIONS

An explanation for the lack of representativeness of the patient data and representation might be a trend to create VPs based on fictional patient stories with VP authors trying to minimize complexity and cognitive load for the students. We suggest raising awareness among VP authors concerning personalized representations of patients without overwhelming their students. Our framework can support educators to assess the authenticity and diversity of a VP collection.

Effect of problem and scripting-based learning on spine surgical trainees' learning outcomes

PURPOSE

To assess the impact of problem and scripting-based learning (PSBL) on spine surgical trainees' learning outcomes.

METHODS

30 spine surgery postgraduate-year-1 residents (PGY-1s) from the First Hospital of China Medical University were randomly divided into two groups. The first group studied spine surgical skills and developed individual judgment under a conventional didactic model, whereas the PSBL group used PBL and Scripted model. A feedback questionnaire and the satisfaction of residents were evaluated by the first assistant surgeon immediately following each procedure. At the end of the study, residents filled out questionnaires focused on identifying the strengths of each teaching method and took a multiple-choice theoretical examination. The results were analyzed by t tests.

RESULTS

Significant difference was found between the two groups in total mean score of preparedness and performance feedback statement (P = 0.01) and the questionnaire by PGY-1's opinion on the effectiveness of the two teaching methods (P = 0.004). Compared with the non-PSBL group, the PSBL group had significantly higher mean score of pre-operative preparedness (P = 0.01), but there was no significant difference between the two groups in theoretical examination, intra-operative performance, and overall satisfaction with the PGY-1s. The residents found that PSBL could develop their judgment (P = 0.03) and provide greater satisfaction (P = 0.02), and would like to repeat the experience (P = 0.03).

CONCLUSIONS

The PSBL method can activate spine residents' prior knowledge and building on existing cognitive frameworks, which is an important tool for improving pre-operative preparedness. We believe that PSBL is an important first step in training spine residents to become confident and safe spine surgeons.

The Irrelevance Narrative: Queer (In)Visibility in Medical Education and Practice

How might heteronormativity be reproduced and become internalized through biomedical practices? Based on in-depth, person-centered interviews, this article explores the ways heteronormativity works into medical education through the hidden curriculum. As experienced by my informants, case studies often reinforce unconscious heteronormative orientations and heterosexist/homophobic stereotypes about queer patients among straight and queer medical students alike. I introduce the concept of the irrelevance narrative to make sense of how queer medical students take up a heteronormative medical gaze. Despite recognizing that being queer affects how they interact with patients, my informants describe being queer as irrelevant to their delivery of care. I conclude with a discussion of how these preliminary findings can inform research on knowledge production in biomedical education and practice with an eye toward the tensions between personal and professional identity among biomedical practitioners.

Experiencing virtual patients in clinical learning: a phenomenological study

Computerised virtual patients (VPs) are increasingly being used in medical education. With more use of this technology, there is a need to increase the knowledge of students' experiences with VPs. The aim of the study was to elicit the nature of virtual patients in a clinical setting, taking the students' experience as a point of departure. Thirty-one students used VPs as a mandatory part of an early clinical rotation in rheumatology. Using the qualitative approach of phenomenology, we interviewed these students and then analysed data regarding their experiences of VPs as a learning activity. The result shows that students perceived VP activities in relation to actual patients, the clinical context and other learning activities. The VPs represented typical clinical cases which encouraged clinical reasoning and allowed for decision making. The students experienced the activities as integrating biomedical knowledge and clinical experience, providing structure that prepared for the unstructured clinical environment and patient encounters under unstressful conditions. However, the VPs were experienced as lacking the emotional interactivity and complexity of actual patients. Theoretical frameworks of clinical reasoning and experiential learning are suggested as foundations for further educational integration of VPs in the clinical environment. VP activities during clinical rotations provide experiences of clinical reality and allow students to solve problems actively. These features are dependent on VP technology but are also contingent on the surrounding environment.

Six ways problem-based learning cases can sabotage patient-centered medical education

PURPOSE

Problem-based learning (PBL) cases tell a story of a medical encounter; however, the version of the story is typically very biomedical in focus. The patient and her or his experience of the situation are rarely the focus of the case despite a prevalent discourse of patient-centeredness in contemporary medical education. This report describes a qualitative study that explored the question, "How does PBL teach medical students about what matters in medicine?"

METHOD

The qualitative study, culminating in 2008, involved three data collection strategies: (1) a discourse analysis of a set of PBL cases from 2005 to 2006, (2) observation of a PBL tutorial group, and (3) semistructured, in-depth, open-ended interviews with medical educators and medical students.

RESULTS

In this report, using data gathered from 67 PBL cases, 26 hours of observation, and 14 interviews, the author describes six specific ways in which PBL cases-if not thoughtfully conceptualized and authored-can serve to overlook social considerations, thereby undermining a patient-centered approach. These comprise the detective case, the shape-shifting patient, the voiceless PBL person, the joke name, the disembodied PBL person, and the stereotypical PBL person.

CONCLUSIONS

PBL cases constitute an important component of undergraduate medical education. Thoughtful authoring of PBL cases has the potential to reinforce, rather than undermine, principles of patient-centeredness.

Moral imagination in simulation-based communication skills training

Clinical simulation is used in nursing education and in other health professional programs to prepare students for future clinical practice. Simulation can be used to teach students communication skills and how to deliver bad news to patients and families. However, skilled communication in clinical practice requires students to move beyond simply learning superficial communication techniques and behaviors. This article presents an unexplored concept in the simulation literature: the exercise of moral imagination by the health professional student. Drawing from the works of Hume, Aristotle and Gadamer, a conceptualization of moral imagination is first provided. Next, this article argues that students must exercise moral imagination on two levels: towards the direct communication exchange before them; and to the representative nature of simulation encounters. Last, the limits of moral imagination in simulation-based education are discussed.

Advantages of video trigger in problem-based learning

BACKGROUND

Traditionally, paper cases are used as 'triggers' to stimulate learning in problem-based learning (PBL). However, video may be a better medium because it preserves the original language, encourages the active extraction of information, avoids depersonalization of patients and allows direct observation of clinical consultations. In short, it exposes the students to the complexity of actual clinical problems.

AIM

The study aims to find out whether students and facilitators who are accustomed to paper cases would prefer video triggers or paper cases and the reasons for their preference.

METHOD

After students and facilitators had completed a video PBL tutorial, their responses were measured by a structured questionnaire using a modified Likert scale.

RESULTS

A total of 257 students (92%) and 26 facilitators (100%) responded. The majority of students and facilitators considered that using video triggers could enhance the students' observational powers and clinical reasoning, help them to integrate different information and better understand the cases and motivate them to learn. They found PBL using video triggers more interesting and preferred it to PBL using paper cases.

CONCLUSION

Video triggers are preferred by both students and facilitators over paper cases in PBL.

Rich-narrative case study for online PBL in medical education

Case studies are the basis of a well-known medical education pedagogy called problem-based learning (PBL). Traditional case studies are paper based and contain brief medical facts about a patient's illness. The authors of this article argue for a rich-narrative PBL design, and they report on a pilot project that incorporated such a design. The term "rich narrative" in this article covers two attributes. The first is the development of case studies that are rich in narrative information (often called "thick narrative"). The second component of rich narrative is the presentation of these thick narrative case studies in a media-rich format-that is, video rather than the traditional paper-based cases. Rich-narrative case studies may provide a more robust context for learning than traditional case studies because the rich cases more accurately reflect the complex reality of patient presentation and interaction. They also may help to lay the foundation for the development of a more holistic and patient-centered awareness during the training of health professionals. The use of video as a case presentation tool adds to this robust depiction of the patient as a complete human being rather than a collection of written symptoms. The authors discuss the power of narrative in learning, the significance of rich-narrative in medical education, the steps they took to develop a video-based, rich-narrative case study for online PBL tutorials at Simon Fraser University, and the evaluation of their prototype used in 2008.

12 Tips: Guidelines for authoring virtual patient cases

BACKGROUND

Virtual patient cases are an increasingly utilized and compelling pedagogical strategy for medical education informatics. They provide educators with the opportunity to develop richly layered, multidimensional teaching situations for their learners. However, 'virtual patients are notoriously difficult to author, adapt and exchange' (MedBiquitous Virtual Patient Specification, Virtual Patient Working Group 2007), and case creation can be daunting. Authors may be uncertain about the process of virtual patient case development and this can translate into ambiguity and hesitation.

AIMS

This installment of the '12 tips' presents specific guidelines that are intended to provide medical educators with guidelines to facilitate the development of virtual patient cases.

METHODS

These 12 tips are based upon comprehensive, research-based, theory-grounded and criterion-referenced guidelines and founded in pedagogical principles, theories of cognition, and recognition of current technology and availability of authoring applications.

RESULTS

It is anticipated that the 12 tips will provide medical educators interested in authoring virtual patient cases one set of useful guidelines to facilitate the process.

CONCLUSIONS

Virtual patient cases provide medical educators with an innovative tool for medical education. These guidelines will assist authors in case development.

A conceptual framework for the use of illness narratives in medical education

The use of narratives, including physicians' and patients' stories, literature, and film, is increasingly popular in medical education. There is, however, a need for an overarching conceptual framework to guide these efforts, which are often dismissed as "soft" and placed at the margins of medical school curricula. The purpose of this article is to describe the conceptual basis for an approach to patient-centered medical education and narrative medicine initiated at the University of Michigan Medical School in the fall of 2003. This approach, the Family Centered Experience, involves home visits and conversations between beginning medical students and patient volunteers and their families and is aimed at fostering humanism in medicine. The program incorporates developmental and learning theory, longitudinal interactions with individuals with chronic illness, reflective learning, and small-group discussions to explore the experience of illness and its care. The author describes a grounding of this approach in theories of empathy and moral development and clarifies the educational value that narratives bring to medical education. Specific pedagogical considerations, including use of activities to create "cognitive disequilibrium" and the concept of transformative learning, are also discussed and may be applied to narrative medicine, professionalism, multicultural education, medical ethics, and other subject areas in medical education that address individuals and their health care needs in society.

Problem-based learning and larger student groups: mutually exclusive or compatible concepts - a pilot study

BACKGROUND

Problem-based learning is recognised as promoting integration of knowledge and fostering a deeper approach to life-long learning, but is associated with significant resource implications. In order to encourage second year undergraduate medical students to integrate their pharmacological knowledge in a professionally relevant clinical context, with limited staff resources, we developed a novel clustered PBL approach. This paper utilises preliminary data from both the facilitator and student viewpoint to determine whether the use of this novel methodology is feasible with large groups of students.

METHODS

Students were divided into 16 groups (20-21 students/group) and were allocated a PBL facilitator. Each group was then divided into seven subgroups, or clusters, of 2 or 3 students wh each cluster being allocated a specific case. Each cluster was then provided with more detailed clinical information and studied an individual and distinct case-study. An electronic questionnaire was used to evaluate both student and facilitator perception of this clustered PBL format, with each being asked to rate the content, structure, facilitator effectiveness, and their personal view of the wider learning experience.

RESULTS

Despite initial misgivings, facilitators managed this more complex clustered PBL methodology effectively within the time restraints and reported that they enjoyed the process. They felt that the cases effectively illustrated medical concepts and fitted and reinforced the students' pharmacological knowledge, but were less convinced that the scenario motivated students to use additional resources or stimulated their interest in pharmacology. Student feedback was broadly similar to that of the facilitators; although they were more positive about the scenario stimulating the use of additional resources and an interest in pharmacology.

CONCLUSION

This clustered PBL methodology can be successfully used with larger groups of students. The key to success lies with challenging and well situated clinically relevant cases together with enthusiastic facilitators. Facilitator enjoyment of the PBL process may be related to adequate training and previous PBL experience, rather than academic background. The smaller number of facilitators required using this clustered PBL approach allows for facilitators with 'a belief in the philosophy of PBL' to volunteer which would again impact on the success of the process.

Collecting stories: is it research? Is it good research? Preliminary guidance based on a Delphi study

CONTEXT

The use of narratives (stories) in research, education, audit and evaluation is increasingly common, but there is no consensus on when research ethics committee approval is necessary for such studies or what counts as 'good narrative research'.

OBJECTIVE

This study aimed to produce preliminary guidance for researchers, reviewers and ethics committees on what to classify as narrative research in health care and how to evaluate it.

METHODS

We carried out a 3-round Delphi study on a volunteer sample of 20 academic researchers, practitioners and service users who were active in narrative health research and its application. After reading academic papers on narrative theory and method, and via extensive online discussion, participants generated a set of preliminary statements. Each participant ranked these on a 9-point Likert scale for relevance and validity (round 1), and then received feedback on his or her scorings compared with the group median and range for each item. This cycle of group discussion, revision of statements, individual rankings and aggregation of scores was repeated twice.

RESULTS

The study produced a definition of narrative research which allows such work to be distinguished from the non-research use of stories in health care, and preliminary quality standards for evaluating narrative research. Most participants on this heterogeneous panel felt able to sign up to the final guidance. Residual disagreements were generally attributable to incommensurabilities in philosophical positions.

CONCLUSIONS

Research ethics committees and scientific reviewers may find the guiding principles in this paper a useful starting point for further reflection and discussion about narrative research studies.

How video cases should be used as authentic stimuli in problem-based medical education

PURPOSE

To examine problem-based learning (PBL) students' views on the added value of video cases compared to text-based cases in the pre-clinical phase of undergraduate medical education and on the conditions for productive use of video in tutorial group discussions.

METHOD

Participants were 2nd-year students who had completed a PBL programme featuring video cases. Three groups of 6-8 randomly selected students participated in focus-group interviews guided by a moderator using a 'questioning route'. The interviews were audiotaped, transcribed and analysed. The summary reports were approved by the students.

RESULTS

According to the students, the video cases enabled them to create realistic mental pictures of disorders, provided integrated pictures of patients as people, which challenged them to elaborate the cases seriously and were more memorable than text-based cases. Cases that students perceived as fostering the productive use of video were neither too directive nor too complete, tailored to students' prior knowledge, short, varied in design and complementary to other materials. The cases should be viewed in a structured, purposeful manner, with cues, instructions and prompts to focus attention on essential issues.

CONCLUSION

The video cases were generally perceived as a valuable stimulus for group discussions in PBL. However, productive use depended on specific conditions. Many of the advantages and conditions mentioned are supported by earlier non-empirical claims in the literature or can be explained by theory and empirical studies on symbol systems. Future observational studies should address the effects of specific attributes of video as a medium.

Using clinical experience in discussion within problem-based learning groups

A key principle in problem-based learning (PBL) is the student linking learning from different sources to enrich understanding. We have explored how medical students based in a clinical environment use clinical experience within PBL groups. We recorded the discussion of 12 third-year groups, which were meeting for the second time on a PBL case, where students report back on the learning objectives. Discussions covering five separate PBL paper cases were recorded. Analysis of the transcripts was based on constant comparative method using a coding framework. The range of discussion segments of clinical experience was 2-15, with 9 of 12 groups having at least five separate segments. Our initial coding framework covered 10 categories, of which the most common were: a specific patient encounter (19%); an experience in the community (15%); and a personal health experience (15%). Students often used emotive phrases with 37 examples in the clinical experience segments compared with 9 from the longer non-clinical discussion. Most clinical descriptions triggered further discussion with almost half leading to some related medical topic. The discussion segments were subsequently coded into; 'confirming' (40); 'extending' (40); and 'disconfirming' (16) the understanding of the group for that topic. Discussion of clinical experience encouraged students to connect to the affective aspects of learning. It helped students to bridge between the tutorial and real clinical contexts. A clinical experience was often a powerful pivotal point, which confirmed, extended or refuted what was being discussed.

Evaluation of an interactive case simulation system in dermatology and venereology for medical students

BACKGROUND

Most of the many computer resources used in clinical teaching of dermatology and venereology for medical undergraduates are information-oriented and focus mostly on finding a "correct" multiple-choice alternative or free-text answer. We wanted to create an interactive computer program, which facilitates not only factual recall but also clinical reasoning.

METHODS

Through continuous interaction with students, a new computerised interactive case simulation system, NUDOV, was developed. It is based on authentic cases and contains images of real patients, actors and healthcare providers. The student selects a patient and proposes questions for medical history, examines the skin, and suggests investigations, diagnosis, differential diagnoses and further management. Feedback is given by comparing the user's own suggestions with those of a specialist. In addition, a log file of the student's actions is recorded. The program includes a large number of images, video clips and Internet links. It was evaluated with a student questionnaire and by randomising medical students to conventional teaching (n = 85) or conventional teaching plus NUDOV (n = 31) and comparing the results of the two groups in a final written examination.

RESULTS

The questionnaire showed that 90% of the NUDOV students stated that the program facilitated their learning to a large/very large extent, and 71% reported that extensive working with authentic computerised cases made it easier to understand and learn about diseases and their management. The layout, user-friendliness and feedback concept were judged as good/very good by 87%, 97%, and 100%, respectively. Log files revealed that the students, in general, worked with each case for 60-90 min. However, the intervention group did not score significantly better than the control group in the written examination.

CONCLUSION

We created a computerised case simulation program allowing students to manage patients in a non-linear format supporting the clinical reasoning process. The student gets feedback through comparison with a specialist, eliminating the need for external scoring or correction. The model also permits discussion of case processing, since all transactions are stored in a log file. The program was highly appreciated by the students, but did not significantly improve their performance in the written final examination.
