Gut feelings as a third track in general practitioners' diagnostic reasoning

BACKGROUND

General practitioners (GPs) are often faced with complicated, vague problems in situations of uncertainty that they have to solve at short notice. In such situations, gut feelings seem to play a substantial role in their diagnostic process. Qualitative research distinguished a sense of alarm and a sense of reassurance. However, not every GP trusted their gut feelings, since a scientific explanation is lacking.

OBJECTIVE

This paper explains how gut feelings arise and function in GPs' diagnostic reasoning.

APPROACH

The paper reviews literature from medical, psychological and neuroscientific perspectives.

CONCLUSIONS

Gut feelings in general practice are based on the interaction between patient information and a GP's knowledge and experience. This is visualized in a knowledge-based model of GPs' diagnostic reasoning emphasizing that this complex task combines analytical and non-analytical cognitive processes. The model integrates the two well-known diagnostic reasoning tracks of medical decision-making and medical problem-solving, and adds gut feelings as a third track. Analytical and non-analytical diagnostic reasoning interacts continuously, and GPs use elements of all three tracks, depending on the task and the situation. In this dual process theory, gut feelings emerge as a consequence of non-analytical processing of the available information and knowledge, either reassuring GPs or alerting them that something is wrong and action is required. The role of affect as a heuristic within the physician's knowledge network explains how gut feelings may help GPs to navigate in a mostly efficient way in the often complex and uncertain diagnostic situations of general practice. Emotion research and neuroscientific data support the unmistakable role of affect in the process of making decisions and explain the bodily sensation of gut feelings.The implications for health care practice and medical education are discussed.

Twelve tips for teaching expertise in clinical reasoning

BACKGROUND

Clinical reasoning is one of the most critical skills to teach to medical learners, yet clinician educators rarely receive adequate training on how to teach this topic.

AIMS

To enhance clinician educators' ability to teach clinical reasoning.

METHODS

I conducted a review of cognitive, medical decision making, and expertise theory literature to develop practical tips that could be applied to typical teaching encounters.

RESULTS

Through the literature review, twelve tips were designed to provide a blueprint for teaching clinical reasoning on the wards or in the clinics.

CONCLUSIONS

Teaching clinical reasoning is important and feasible. Teachers who explicitly teach problem solving and decision making may help learners to improve their diagnostic accuracy and treatment choices.

Pediatrics milestone project: next steps toward meaningful outcomes assessment

In the September 2010 issue of JGME, the Pediatric Milestones Working Group published "The Pediatrics Milestones: Conceptual Framework, Guiding Principles, and Approach to Development", a document that describes the construction of the first iteration of the Pediatric Milestones. These Milestones were developed by the Working Group as a group of practical behavioral expectations for each of the 52 sub-competencies. In constructing these Milestones, the authors were cognizant of the need to ground the Milestones themselves in evidence, theories or other conceptual frameworks that would provide the basis for the ontogeny of development for each sub-competency. During this next phase of the Milestones development, the process will continue with consultation with content experts and consideration of assessment of Milestones. We have described possible measurement tools, explored threats to validity, establishment of benchmarks, and possible approaches to reporting of performance. The vision of the Pediatrics Milestone Project is to understand the development of a pediatrician from entry into medical school through the twilight of a physician's career, and the work will require a collaborative effort of the undergraduate and graduate medical education communities, and the accrediting and certifying bodies.

A "medical student practice profile" as the foundation for a case-based curriculum revision

BACKGROUND

In 2001, the Keck School of Medicine of the University of Southern California initiated a major curriculum reform with fully integrated teaching of the basic sciences.

DESCRIPTION

The new curriculum integrated a set of selected clinical cases called the student practice profile (SPP). The SPP cases were designed to (a) define the core target knowledge base and essential clinical experience of all graduating students, (b) to improve the relevance of basic science teaching, and (c) to serve as the overarching organizational structure for the 4-year curriculum.

EVALUATION

Evaluation data demonstrated that implementation of the SPP project has been moderately successful and students have reported high exposure to the SPP cases and confidence in their ability to diagnose and manage problems. Improvement in teaching the basic sciences in a clinically relevant manner is suggested by a small continued improvement in USMLE scores since the SPP project was fully implemented.

CONCLUSIONS

The SPP design represents a uniquely successful pathway to curriculum redesign.

The pediatrics milestones: conceptual framework, guiding principles, and approach to development

BACKGROUND

The Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Pediatrics (ABP) have partnered to initiate the Pediatrics Milestone Project to further refine the 6 ACGME competencies and to set performance standards as part of the continued commitment to document outcomes of training and program effectiveness.

INTERVENTION

Members of the Pediatrics Milestone Project Working Group searched the medical literature and beyond to create a synopsis of models and evidence for a developmental ontogeny of the elements for 52 subcompetencies. For each subcompetency, we created a series of Milestones, grounded in the literature. The milestones were vetted with the entire working group, engaging in an iterative process of revisions until reaching consensus that their narrative descriptions (1) included all critical elements, (2) were behaviorally based, (3) were properly sequenced, and (4) represented the educational continuum of training and practice.

OUTCOMES

We have completed the first iteration of milestones for all subcompetencies. For each milestone, a synopsis of relevant literature provides background, references, and a conceptual framework. These milestones provide narrative descriptions of behaviors that represent the ontogeny of knowledge, skill, and attitude development across the educational continuum of training and practice.

DISCUSSION

The pediatrics milestones take us a step closer to meaningful outcome assessment. Next steps include undertaking rigorous study, making appropriate modifications, and setting performance standards. Our aim is to assist program directors in making more reliable and valid judgments as to whether a resident is a "good doctor" and to provide outcome evidence regarding the program's success in developing doctors.

Developing expertise in surgery

The concept of expertise is widely embraced but poorly defined in surgery. Dictionary definitions differentiate between authority and experience, while a third view sees expertise as a mind-set rather than a status. Both absolute and relative models of expertise have been developed, and each allows a richer understanding of the application of these concepts to emerge. Trainees must develop both independent and interdependent expertise, and an appreciation of the essentially constructivist and uncertain nature of medical knowledge. Approach may be more important than innate talent; the concepts of 'flow', sustained 'deliberate practice' and 'adaptive expertise' are examples of expert approaches to learning. Non-analytical reasoning plays a key role in decision making at expert levels of practice. A technically gifted surgeon may be seen as a safety hazard rather than an expert if inter-dependent expertise has not been developed. Key roles of a surgical educator are to facilitate the development of an expert approach to education and to enable entry into and movement towards the centre of an expert community of practice.

No content without context: integrating basic, clinical, and social sciences in a pre-clerkship curriculum

BACKGROUND

The basic science curricula in medical schools ultimately succeed or fail at the bedside when students must draw on their pre-clerkship experiences as they learn to form nuanced clinical decisions. Given this expectation, learning context becomes as decisive as content in determining students' recall and application.

AIMS

Using the pre-clerkship medical curriculum at the University of California, Los Angeles, as an example, we illustrate how traditional biomedical sciences can be integrated with clinical sciences in a comprehensive foundational curriculum following curricular design features and teaching methods based on learning principles from cognitive psychology and education.

METHODS

Multiple planning teams of faculty and students collaborated in the design of the Human Biology and Disease (HB&D) curriculum. Broad participation, careful selection of course chairs, the assistance of educational consultants, ongoing oversight structures, and faculty development were used to develop and sustain the curriculum.

RESULTS

The resulting HB&D curriculum features an interdisciplinary spiral block structure including interactive lecture formats, integrative formative and summative examinations, self- and peer-taught laboratories, and problem-based learning with innovative variations.

CONCLUSION

Our fully integrated, spiral, pre-clerkship curriculum built on repeating interdisciplinary blocks and longitudinal threads has yielded encouraging results as well as some specific innovations that other schools or individual teachers may find valuable to adapt for use in their own settings.

Conceptual frameworks to illuminate and magnify

CONTEXT

In a recent study of the quality of reporting experimental studies in medical education, barely half the articles examined contained an explicit statement of the conceptual framework used. Conceptual frameworks represent ways of thinking about a problem or a study, or ways of representing how complex things work. They can come from theories, models or best practices. Conceptual frameworks illuminate and magnify one's work. Different frameworks will emphasise different variables and outcomes, and their inter-relatedness. Educators and researchers constantly use conceptual frameworks to guide their work, even if they themselves are not consciously aware of the frameworks.

METHODS

Three examples are provided on how conceptual frameworks can be used to cast development and research projects in medical education. The examples are accompanied by commentaries and a total of 13 key points about the nature and use of conceptual frameworks.

CONCLUSIONS

Ultimately, scholars are responsible for making explicit the assumptions and principles contained in the conceptual framework(s) they use in their development and research projects.

An expert-performance perspective of research on medical expertise: the study of clinical performance

CONTEXT

Three decades ago Elstein et al. published their classic book on medical expertise, in which they described their failure to identify superior performance by peer-nominated diagnosticians using high- and low-fidelity simulations of the everyday practice of doctors.

OBJECTIVE

This paper reviews the results of subsequent research, with a particular emphasis on the progress toward Elstein et al.'s goal of capturing the essence of superior clinical performance in standardised settings in order to improve clinical practice.

RESULTS

Research following publication of Elstein et al.'s book was influenced by laboratory research in cognitive psychology, which resulted in a redirection of its original focus on capturing clinical performance in practice to studies of changes in cognitive processes as functions of extended clinical experience. There is currently renewed interest in linking laboratory research with studies of the acquisition of superior (expert) performance in the clinic.

CONCLUSIONS

Research on medical expertise and simulation training in technical procedures and diagnosis provide exciting opportunities for establishing translational research on the acquisition of superior (expert) performance in the clinic by capturing it with representative tasks in the laboratory, reproducing it for experimental analysis, and developing training activities, such as deliberate practice, that can induce measurable improvements in performance in the clinic.
