Background: GPs consider their gut feelings a valuable tool in clinical reasoning. Research suggests patients' gut feelings may be a useful contribution to that process. Describing these feelings more precisely could improve primary care professionals' (PCPs) recognition of patients' gut feelings and insight into the underlying reasons. These descriptions would also enable a thorough examination of the validity of patients' gut feelings and their contribution to professionals' clinical reasoning., Aim: To gather the words and phrases that patients or their relatives use to share their gut feelings with primary care professionals and what they convey and imply., Design and Setting: Qualitative study of Dutch and Belgian patients visiting an out-of-hours GP service or a GP's office., Method: Face-to-face semi-structured interviews were carried out with 47 patients. Interviews were coded using a descriptive content analysis in an iterative process until data sufficiency., Results: Patients or their relatives expressed their gut feelings by using words relating to trusting or not trusting the situation, or to changes in normal patterns. Their gut feelings are most often felt as a sense of alarm. In general, patients experiencing a sense of alarm, particularly mothers of sick children, were convinced that something was wrong and had often learned to trust their gut feeling. A gut feeling was the main reason to contact a PCP. Patients generally felt that their gut feelings were taken seriously., Conclusion: The findings of this study provide an insight into how patients and relatives may express their gut feelings about their own or their relative's health and how they share these feelings with healthcare professionals. This may help clinicians improve their recognition of patients' gut feelings, being particularly alert to a patient or relative using phrases that relate to feelings of not trusting a situation, things seeming wrong or different from normal, and experiencing a sense of alarm. Further research should be carried out into the validity of patients' gut feelings., (© The Authors.)

Context: Medical experts have access to elaborate and integrated knowledge networks consisting of biomedical and clinical knowledge. These coherent knowledge networks enable them to generate more accurate diagnoses in a shorter time. However, students' knowledge networks are less organised and students have difficulties linking theory and practice and transferring acquired knowledge. Therefore we wanted to explore the development and transfer of knowledge of third-year preclinical students on a problem-based learning (PBL) course with real patient contacts., Methods: Before and after a 10-week PBL course with real patients, third-year medical students were asked to think out loud while diagnosing four types of paper patient problems (two course cases and two transfer cases), and explain the underlying pathophysiological mechanisms of the patient features. Diagnostic accuracy and time needed to think through the cases were measured. The think-aloud protocols were transcribed verbatim and different types of knowledge were coded and quantitatively analysed. The written pathophysiological explanations were translated into networks of concepts. Both the concepts and the links between concepts in students' networks were compared to model networks., Results: Over the course diagnostic accuracy increased, case-processing time decreased, and students used less biomedical and clinical knowledge during diagnostic reasoning. The quality of the pathophysiological explanations increased: the students used more concepts, especially more model concepts, and they used fewer wrong concepts and links. The findings differed across course and transfer cases. The effects were generally less strong for transfer cases., Conclusions: Students' improved diagnostic accuracy and the improved quality of their knowledge networks suggest that integration of biomedical and clinical knowledge took place during a 10-week course. The differences between course and transfer cases demonstrate that transfer is complex and time-consuming. We therefore suggest offering students many varied patient contacts with the same underlying pathophysiological mechanism and encouraging students to link biomedical and clinical knowledge., (© 2015 John Wiley & Sons Ltd.)

Diagnostic reasoning is considered to be based on the interaction between analytical and non-analytical cognitive processes. Gut feelings, a specific form of non-analytical reasoning, play a substantial role in diagnostic reasoning by general practitioners (GPs) and may activate analytical reasoning. In GP traineeships in the Netherlands, trainees mostly see patients alone but regularly consult with their supervisors to discuss patients and problems, receive feedback, and improve their competencies. In the present study, we examined the discussions of supervisors and their trainees about diagnostic reasoning in these so-called tutorial dialogues and how gut feelings feature in these discussions. 17 tutorial dialogues focussing on diagnostic reasoning were video-recorded and transcribed and the protocols were analysed using a detailed bottom-up and iterative content analysis and coding procedure. The dialogues were segmented into quotes. Each quote received a content code and a participant code. The number of words per code was used as a unit of analysis to quantitatively compare the contributions to the dialogues made by supervisors and trainees, and the attention given to different topics. The dialogues were usually analytical reflections on a trainee's diagnostic reasoning. A hypothetico-deductive strategy was often used, by listing differential diagnoses and discussing what information guided the reasoning process and might confirm or exclude provisional hypotheses. Gut feelings were discussed in seven dialogues. They were used as a tool in diagnostic reasoning, inducing analytical reflection, sometimes on the entire diagnostic reasoning process. The emphasis in these tutorial dialogues was on analytical components of diagnostic reasoning. Discussing gut feelings in tutorial dialogues seems to be a good educational method to familiarize trainees with non-analytical reasoning. Supervisors need specialised knowledge about these aspects of diagnostic reasoning and how to deal with them in medical education.

Weaknesses in the nature of rater judgments are generally considered to compromise the utility of workplace-based assessment (WBA). In order to gain insight into the underpinnings of rater behaviours, we investigated how raters form impressions of and make judgments on trainee performance. Using theoretical frameworks of social cognition and person perception, we explored raters' implicit performance theories, use of task-specific performance schemas and the formation of person schemas during WBA. We used think-aloud procedures and verbal protocol analysis to investigate schema-based processing by experienced (N = 18) and inexperienced (N = 16) raters (supervisor-raters in general practice residency training). Qualitative data analysis was used to explore schema content and usage. We quantitatively assessed rater idiosyncrasy in the use of performance schemas and we investigated effects of rater expertise on the use of (task-specific) performance schemas. Raters used different schemas in judging trainee performance. We developed a normative performance theory comprising seventeen inter-related performance dimensions. Levels of rater idiosyncrasy were substantial and unrelated to rater expertise. Experienced raters made significantly more use of task-specific performance schemas compared to inexperienced raters, suggesting more differentiated performance schemas in experienced raters. Most raters started to develop person schemas the moment they began to observe trainee performance. The findings further our understanding of processes underpinning judgment and decision making in WBA. Raters make and justify judgments based on personal theories and performance constructs. Raters' information processing seems to be affected by differences in rater expertise. The results of this study can help to improve rater training, the design of assessment instruments and decision making in WBA.

Background: Family physicians perceive that gut feelings, i.e. a 'sense of reassurance' or a 'sense of alarm', play a substantial role in diagnostic reasoning. A measuring instrument is desirable for further research. Our objective is to validate a questionnaire measuring the presence of gut feelings in diagnostic reasoning., Methods: We constructed 16 case vignettes from real practice situations and used the accompanying 'sense of reassurance' or the 'sense of alarm' as reference labels. Based on the results of an initial study (26 family physicians), we divided the case vignettes into a group involving a clear role for the sense of reassurance or the sense of alarm and a group involving an ambiguous role. 49 experienced family physicians evaluated each 10 vignettes using the questionnaire. Construct validity was assessed by testing hypotheses and an internal consistency procedure was performed., Results: As hypothesized we found that the correlations between the reference labels and corresponding items were high for the clear-case vignettes (0.59 - 0.72) and low for the ambiguous-case vignettes (0.08 - 0.23). The agreement between the classification in clear sense of reassurance, clear sense of alarm and ambiguous case vignettes as derived from the initial study and the study population's judgments was substantial (Kappa = 0.62). Factor analysis showed one factor with opposites for sense of reassurance and sense of alarm items. The questionnaire's internal consistency was high (0.91). We provided a linguistic validated English-language text of the questionnaire., Conclusions: The questionnaire appears to be valid. It enables quantitative research into the role of gut feelings and their diagnostic value in family physicians' diagnostic reasoning.

Correctly predicting the course of a patient's pattern of symptoms, even if no diagnosis has (yet) been established, is a core task of the general practitioner (GP). This is a complex task requiring extensive knowledge and experience, as the presentation of diseases in primary care regularly deviates from what doctors learn at medical school. In addition, knowledge among GPs about clinical pictures requiring immediate action is not always sufficient. Finally, GPs' context and experiential knowledge are decreasing due to changes in the organization of care. In the authors' opinion, postgraduate courses for GPs insufficiently address these issues. Postgraduate courses should teach them about serious diseases that must not be missed, about uncommon presentations of common diseases and about the role of gut feelings in diagnostic thinking and the way to act on these feelings. GPs should be obliged to devote part of their compulsory postgraduate training to these subjects.

Background: In this study, the effect of guidance on students' performance was investigated. This effect was hypothesized to be manifested through a reduction of cognitive load and enhancement of self-explanations., Aim: The goal of this study was to investigate the effect of guiding questions on students' understanding of statistics., Sample and Method: In an experimental setting, two randomly selected groups of students (N= 49) answered achievement and transfer questions on statistics as a measure of performance. Students in the intervention condition were given guiding questions to direct their way of reasoning before they answered the achievement questions. The students in the control condition were asked to write down their way of thinking before they answered the same achievement questions. In this way, both groups were stimulated to self-explain, but only the reasoning processes of the students in the intervention condition were guided., Results and Conclusion: It was found that students in the intervention condition performed significantly better on achievement and transfer questions and that this effect of guidance was mediated by self-explanations. Attitude towards statistics was positively related to performance., (©2011 The British Psychological Society.)

Background: Education is aimed at students reaching conceptual understanding of the subject matter, because this leads to better performance and application of knowledge. Conceptual understanding depends on coherent and error-free knowledge structures. The construction of such knowledge structures can only be accomplished through active learning and when new knowledge can be integrated into prior knowledge., Aims: The intervention in this study was directed at both the activation of students as well as the integration of knowledge., Sample: Undergraduate university students from an introductory statistics course, in an authentic problem-based learning (PBL) environment, were randomly assigned to conditions and measurement time points., Method: In the PBL tutorial meetings, half of the tutors guided the discussions of the students in a traditional way. The other half guided the discussions more actively by asking directive and activating questions. To gauge conceptual understanding, the students answered open-ended questions asking them to explain and relate important statistical concepts., Results and Conclusions: Results of the quantitative analysis show that providing directive tutor guidance improved understanding. Qualitative data of students' misconceptions seem to support this finding. Long-term retention of the subject matter seemed to be inadequate., (©2010 The British Psychological Society.)

Medical professionals need to keep on learning as part of their everyday work to deliver high-quality health care. Although the importance of physicians' learning is widely recognized, few studies have investigated how they learn in the workplace. Based on insights from deliberate practice research, this study examined the activities physicians engage in during their work that might further their professional development. As deliberate practice requires a focused effort to improve performance, the study also examined the goals underlying this behaviour. Semi-structured interviews were conducted with 50 internal medicine physicians: 19 residents, 18 internists working at a university hospital, and 13 working at a non-university hospital. The results showed that learning in medical practice was very much embedded in clinical work. Most relevant learning activities were directly related to patient care rather than motivated by competence improvement goals. Advice and feedback were sought when necessary to provide this care. Performance standards were tied to patients' conditions. The patients encountered and the discussions with colleagues about patients were valued most for professional development, while teaching and updating activities were also valued in this respect. In conclusion, physicians' learning is largely guided by practical experience rather than deliberately sought. When professionals interact in diagnosing and treating patients to achieve high-quality care, their experiences contribute to expertise development. However, much could be gained from managing learning opportunities more explicitly. We offer suggestions for increasing the focus on learning in medical practice and further research.

Context: Real-patient contacts in problem-based undergraduate medical education are promoted as a good way to introduce biomedical and (in)formal clinical knowledge early in the curriculum and thereby to foster the development of coherent and integrated knowledge networks. There are concerns, however, that such contacts may cause students to focus on clinical knowledge to the neglect of biomedical knowledge, and that group discussions may be dominated by teachers. We examined these concerns by addressing the following questions in the context of group sessions in which students prepare for and report on real-patient contacts. To what extent are biomedical and (in)formal clinical knowledge addressed? To what extent are these knowledge types addressed by students or tutors? Are connections made between biomedical and clinical knowledge?, Methods: We videotaped and transcribed six preparation and six reporting group sessions (two preparation and two reporting phases for each of three groups) held with students in Year 3 of the problem-based curriculum at Maastricht University. During this year, real patients rather than paper patients are used. Qualitative analysis software was used to code propositions in the transcriptions in order to identify different kinds of knowledge and different functions of biomedical knowledge., Results: Formal clinical knowledge was the subject of 40.7% and 34.8% of propositions during the preparation and reporting phases, respectively. The corresponding percentages for biomedical knowledge were 15.0% and 28.0%. Tutors accounted for 63.4% of propositions during the preparation phase, and students for 80.1% during the reporting phase. Nearly all biomedical knowledge was related to clinical knowledge., Conclusions: It appears that pre-clinical patient encounters can stimulate students to pay attention to both clinical and biomedical knowledge and to how they are connected. Tutor dominance was evident only during the preparation phase. Further research is needed to investigate whether pre-clinical patient contacts promote the development of coherent and integrated knowledge networks., (© Blackwell Publishing Ltd 2011.)

Background: Worked examples are very effective for novice learners. They typically present a written-out ideal (didactical) solution for learners to study., Aims: This study used worked examples of patient history taking in physiotherapy that presented a non-didactical solution (i.e., based on actual performance). The effects of model expertise (i.e., worked example based on advanced, third-year student model or expert physiotherapist model) in relation to students' expertise (i.e., first- or second-year) were investigated., Sample: One hundred and thirty-four physiotherapy students (61 first-year and 73 second-year)., Methods: Design was 2 × 2 factorial with factors 'Student Expertise' (first-year vs. second-year) and 'Model Expertise' (expert vs. advanced student). Within expertise levels, students were randomly assigned to the Expert Example or the Advanced Student Example condition. All students studied two examples (content depending on their assigned condition) and then completed a retention and test task. They rated their invested mental effort after each example and test task., Results: Second-year students invested less mental effort in studying the examples, and in performing the retention and transfer tasks than first-year students. They also performed better on the retention test, but not on the transfer test. In contrast to our hypothesis, there was no interaction between student expertise and model expertise: all students who had studied the Expert examples performed better on the transfer test than students who had studied Advanced Student Examples., Conclusions: This study suggests that when worked examples are based on actual performance, rather than an ideal procedure, expert models are to be preferred over advanced student models.

Objectives: In health education, the design of written materials is seldom subject to experimental tests. Using insights from cognitive-ergonomic literature on usability we tested a brochure against three stepwise improved versions. Effects were assessed of pictorials that flagged references in the brochure text, the use of tabs and colour coding of these pictorials and tabs, on finding information in the brochure., Methods: One hundred Dutch adults from the general population were videotaped while looking up search items. Dependent measures relating to search effectiveness, efficiency, satisfaction and learnability were extracted., Results: Results showed a general inferiority of the original brochure. The presence of coloured tabs and pictorials contributed to a more usable brochure design, although errors were still made., Conclusion: It is concluded that this kind of research may provide valuable insights for more effective health education material design and thus contributes to the effectiveness of health education practice.

Objective: The present study aimed to contribute to the design of effective health education information. Based on cognitive-psychological theory, pictures were expected to improve understanding of two existing textual instructions for using asthma devices (inhaler chamber and peak flow meter). From an analysis of the affordances and constraints of both devices this effect was expected to be stronger with the inhaler chamber than with the peak flow meter., Methods: To test this, both instructions were systematically illustrated with seven line-drawings visualizing the actions. In two separate randomized controlled trials with in total 99 participants from the general public, the original text-only versions were compared to the text-picture versions of the same instruction. Dependent variables were participants' recall of the instructions and the quality of their performance with the instruction observed from video-recordings., Results: Conform expectations, the results showed significant positive effects of pictures on recall and performance in both instructions, especially with the inhaler chamber., Conclusion: Thus, pictures may contribute to a better comprehension and use of medical devices that are inherently less clear., Practice Implications: Health educators may optimize instruction design by careful analysis of the device with instruction and observational testing with potential users.

This study examined the effect of graphic organizers on the comprehension of a health education brochure text and compared subjective with objective comprehension measures. Graphic organizers are graphical depictions of relations among concepts in a text. Participants read a brochure text about asthma with and without these organizers, and subjective and objective text comprehension was measured. It was found that graphic organizers had effects on four levels of objective comprehension as indicated by open comprehension questions. However, on the subjective comprehension measure using Likert-type scales, the groups with and without graphic organizers did not differ from each other. It is concluded that health education texts could benefit from relatively simple techniques to increase comprehension. Furthermore, in developing health education materials, comprehension should be measured objectively.

Background: This study was directed at illuminating a well known phenomenon in the medical expertise literature, the 'intermediate effect' in clinical case recall. This robust phenomenon consists of the finding that medical students of intermediate levels of expertise outperform both experts and novices in clinical case recall after diagnosing cases. It deals in particular with the findings of OME researchers who have reported a monotonically increasing recall with level of expertise., Purpose: To address possible causes for this anomaly in medical expertise and to experimentally demonstrate how data elaboration can cause expertise effects in clinical case recall., Method: Expert nephrologists, intermediate level students and novices were presented with 6 medical cases under 3 different conditions: laboratory data cases without special instructions, laboratory data cases with instructions to elaborate, and cases with laboratory data and a relevant clinical context., Results: Only when participants were required to elaborate on each of the information units presented to them did case recall show an expertise effect. If laboratory data are framed within the context of a patient's history and physical examination data, the 'intermediate effect' appears., Conclusions: The instructions used in the elaboration condition seem to have induced a deeper, more detailed, analysis of the patient case. It is therefore interesting to note that these instructions only affected the recall of the experts and had no effect on the novices' or intermediates' recall. We might conclude from this that expertise effects in clinical case recall are only produced when the normal processing of patient information is disrupted.

The aim of this study was to gain insight into the extent to which health education text writers apply writing principles derived from cognitive psychological theory. Seventeen professional text writers of health education materials participated in a qualitative study, consisting of a rewriting task combined with a think-aloud procedure and a semistructured interview. The verbal data were explored carefully in light of seven text coherence principles that have proven effective in cognitive psychological research to increase text comprehension. Findings indicate text writers vary in their ideas and use of coherence principles to make a text comprehensible. It is argued that the health education profession can benefit greatly from knowledge about cognitive text processing and cognitive coherence principles for realizing effective comprehension of written health education messages.

Introduction: At Maastricht University, the integration of knowledge, skills and attitudes in preclinical medical education is promoted by an 'Adoption Programme', where students carry out assignments in a general practice setting. The assignments are explained and discussed in practical medical coaching groups. The aim of this study was to examine the relationships between the elements that affect learning in the programme., Method: Data from the evaluation questionnaires of 188 medical students were used to test a causal model of learning in the programme. A distinction was made between 'action' and 'reflection on action'. We examined the relationships between perceived instructiveness (the programme's value as a learning experience) and the following variables: comprehensibility; feasibility and execution of the assignments; time spent on the assignments, and the direct and indirect influences of the hosting general practitioner (GP) and the practical medical coaching group., Results: Performing the assignments had little effect on perceived instructiveness. Coaching by the hosting GP influenced the execution of assignments mainly by its effect on feasibility. Coaching by the GP and in the practical medical coaching groups barely affected perceived instructiveness., Discussion and Conclusion: The model gives insight into the contribution of aspects of the Adoption Programme to student learning. The results are probably negatively influenced by the insufficient priority given to the Adoption Programme in the practical medical coaching groups and by inadequate instruction given to the GPs for the purposes of their coaching role. More careful planning of patient-related assignments is recommended. Reflection on assignments and feedback on procedures are needed to lift practical experience onto a higher educational level.

Background: Based on cognitive psychological research, a number of theoretical frameworks have been put forward to describe the structure of experts' medical knowledge and to explain experts' case-processing., Purpose: To provide evidence for the theory of knowledge encapsulation, which states that medical knowledge constitutes of interlinked biomedical and clinical knowledge., Methods: Fourth-year medical students, clerks and medical experts evaluated six case descriptions, consisting of laboratory data either with or without a clinical context. For each case description, the participants were required to study the case, to formulate a diagnosis, and to write down everything they could remember of the case., Results: When the laboratory data were not embedded within a clinical context, medical experts' case-processing increased and their diagnostic accuracy became worse. Furthermore, laboratory data recall of medical experts was more elaborate in cases where the laboratory data were presented without a clinical context. Similar results were obtained for students and clerks., Conclusions: The findings are only partially consistent with a prediction made by the theory of knowledge encapsulation. Further research, using a different paradigm than the traditionally used method of free recall, is required to unearth whether medical experts use qualitatively different knowledge structures than novices while solving cases.

A general approach to curriculum design in the context of Problem-Based Learning (PBL) is outlined. Ten general 'steps' for problem-based curriculum development are proposed, using the case study methodology to describe the underlying iterative process. Examples are given from the case of the development of a public health professions education curriculum. The process starts with defining the purpose of the curriculum. General objectives are generated in a top-down fashion. The prior knowledge, skills and misconceptions of future students are considered. A preliminary schedule of the curriculum is developed, including sketches of unit blueprints. These are further elaborated. Unit subgoals are related to planned educational activities. Only then, are the learning materials created, with problem writing as the most important aspect. In developing a problem-based curriculum, assessment deserves special attention, because of its influence on the learning process. Finally, educational organization, curriculum management and evaluation procedures are considered.

Purpose: To investigate the differences between experts, intermediates, and novices in diagnosing and representing clinical cases under various time constraints., Method: Second-, fourth-, and sixth-year medical students, and internists studied, diagnosed, and recalled four clinical cases from internal medicine. Participants were allowed to study each case for either 3 minutes, 1 minute 15 seconds, or 30 seconds. The study replicated in most ways the 1993 clinical case recall study of Schmidt and Boshuizen., Results: As expected, diagnostic accuracy increased with level of expertise. However, this study failed to disclose the intermediate effect in clinical case recall that was found in the original study. Instead, a positive linear relation between expertise level and case recall was found. The discrepancy resulted from more elaborate recall by experts in the present study. Constraining processing time did not effect diagnostic accuracy, but equally affected the recall performances of the participants of all expertise levels. This contrasts with the earlier finding that experts' recall is independent of processing time., Conclusion: Although it is unclear why the experts' case processing was more elaborate in the present study than in the earlier study, it must be concluded that expert medical knowledge is so flexibly organized that experts can easily represent clinical cases in either the encapsulated or the elaborated mode.
