Accuracy of diagnoses predicted from a simple patient questionnaire stratified by the duration of general ambulatory training: an observational study

Purpose

To compare the diagnostic accuracy of diseases predicted from patient responses to a simple questionnaire completed prior to examination by doctors with different levels of ambulatory training in general medicine.

Participants and methods

Before patient examination, five trained physicians, four short-term-trained residents, and four untrained residents examined patient responses to a simple questionnaire and then indicated, in rank order according to their subjective confidence level, the diseases they predicted. Final diagnosis was subsequently determined from hospital records by mentor physicians 3 months after the first patient visit. Predicted diseases and final diagnoses were codified using the International Classification of Diseases version 10. A “correct” diagnosis was one where the predicted disease matched the final diagnosis code.

Results

A total of 148 patient questionnaires were evaluated. The Herfindahl index was 0.024, indicating a high degree of diversity in final diagnoses. The proportion of correct diagnoses was high in the trained group (96 of 148, 65%; residual analysis, 4.4) and low in the untrained group (56 of 148, 38%; residual analysis, −3.6) (χ²=22.27, P<0.001). In cases of correct diagnosis, the cumulative number of correct diagnoses showed almost no improvement, even when doctors in the three groups predicted ≥4 diseases.

Conclusion

Doctors who completed ambulatory training in general medicine while treating a diverse range of diseases accurately predicted diagnosis in 65% of cases from limited written information provided by a simple patient questionnaire, which proved useful for diagnosis. The study also suggests that up to three differential diagnoses are appropriate for diagnostic prediction, while ≥4 differential diagnoses barely improved the diagnostic accuracy, regardless of doctors’ competence in general medicine. If doctors can become able to predict the final diagnosis from limited information, the correct diagnostic outcome may improve and save further consultation hours.

Seeing through the dentist's eyes: video-based clinical demonstrations in preclinical dental training

The clinical demonstration is an established way of bridging the disciplinary content in preclinical and clinical courses. In dentistry, however, clinical demonstrations have often been perceived as less rewarding due to the restricted visual access to the details of the treatment. This study investigated a course in endodontics at the University of Gothenburg, Sweden, in which traditional clinical demonstrations were replaced by instructor-led seminars that enabled students to follow and discuss broadcasted root canal treatments. Two cameras provided overviews of the operating room, whereas a third camera attached to a surgical microscope offered a magnified view of procedures carried out in the inner parts of teeth. The hypothesis was that this arrangement would increase the students' sense of the clinical relevance of basic scientific knowledge. Two focus group interviews were designed to explore the students' perceptions of this change. The students expressed that the video-based seminars offered ample opportunities to integrate theoretical and clinical understanding. The major reasons were that the visualization displayed procedures on a sufficiently detailed level; instructors demonstrated clinical reasoning in situ and provided the context necessary for understanding procedures; and the interactive format encouraged discussions on the generalizability of knowledge beyond the specific case.

Histological knowledge as a predictor of medical students' performance in diagnostic pathology

Over the years, the role and extent of the basic sciences in medical curricula have been challenged by research on clinical expertise, clinical teachers, and medical students, as well as by the development and diversification of the medical curricula themselves. The aim of this study was to examine how prior knowledge of basic histology and histopathology among students predicts early learning of diagnostic pathology. Participants (N=118, representing 91% of the full student cohort) were medical students at the University of Turku, Finland. Data were collected during two preclinical courses that students attended in their first and second years of medical school. The measurements included tests on biomedical and clinical knowledge and a performance test in diagnostic pathology. Second-year performance on the diagnostic pathology examinations was predicted by the students' prior knowledge of histology, but not by the students' prior knowledge of histopathology. Although earlier research has demonstrated similar results in studies with shorter longitudinal designs, the present study demonstrates that the effect remains even if there is a considerably long time delay (a year) between the measurements, thus confirming the long-term value of basic science studies in the preclinical phase.

Analysing clinical reasoning characteristics using a combined methods approach

BACKGROUND

Despite a major research focus on clinical reasoning over the last several decades, a method of evaluating the clinical reasoning process that is both objective and comprehensive is yet to be developed.The aim of this study was to test whether a dual approach, using two measures of clinical reasoning, the Clinical Reasoning Problem (CRP) and the Script Concordance Test (SCT), provides a valid, reliable and targeted analysis of clinical reasoning characteristics to facilitate the development of diagnostic thinking in medical students.

METHODS

Three groups of participants, general practitioners, and third and fourth (final) year medical students completed 20 on-line clinical scenarios -10 in CRP and 10 in SCT format. Scores for each format were analysed for reliability, correlation between the two formats and differences between subject-groups.

RESULTS

Cronbach's alpha coefficient ranged from 0.36 for SCT 1 to 0.61 for CRP 2, Statistically significant correlations were found between the mean f-score of the CRP 2 and total SCT 2 score (0.69); and between the mean f-score for all CRPs and all mean SCT scores (0.57 and 0.47 respectively). The pass/fail rates of the SCT and CRP f-score are in keeping with the findings from the correlation analysis (i.e. 31% of students (11/35) passed both, 26% failed both, and 43% (15/35) of students passed one but not the other test), and suggest that the two formats measure overlapping but not identical characteristics. One-way ANOVA showed consistent differences in scores between levels of expertise with these differences being significant or approaching significance for the CRPs.

CONCLUSION

SCTs and CRPs are overlapping and complementary measures of clinical reasoning. Whilst SCTs are more efficient to administer, the use of both measures provides a more comprehensive appraisal of clinical skills than either single measure alone, and as such could potentially facilitate the customised teaching of clinical reasoning for individuals. The modest reliability of SCTs and CRPs in this study suggests the need for an increased number of items for testing. Further work is needed to determine the suitability of a combined approach for assessment purposes.

Functional Neuroimaging Correlates of Burnout among Internal Medicine Residents and Faculty Members

Burnout is prevalent in residency training and practice and is linked to medical error and suboptimal patient care. However, little is known about how burnout affects clinical reasoning, which is essential to safe and effective care. The aim of this study was to examine how burnout modulates brain activity during clinical reasoning in physicians. Using functional Magnetic Resonance Imaging (fMRI), brain activity was assessed in internal medicine residents (n = 10) and board-certified internists (faculty, n = 17) from the Uniformed Services University (USUHS) while they answered and reflected upon United States Medical Licensing Examination and American Board of Internal Medicine multiple-choice questions. Participants also completed a validated two-item burnout scale, which includes an item assessing emotional exhaustion and an item assessing depersonalization. Whole brain covariate analysis was used to examine blood-oxygen-level-dependent (BOLD) signal during answering and reflecting upon clinical problems with respect to burnout scores. Higher depersonalization scores were associated with less BOLD signal in the right dorsolateral prefrontal cortex and middle frontal gyrus during reflecting on clinical problems and less BOLD signal in the bilateral precuneus while answering clinical problems in residents. Higher emotional exhaustion scores were associated with more right posterior cingulate cortex and middle frontal gyrus BOLD signal in residents. Examination of faculty revealed no significant influence of burnout on brain activity. Residents appear to be more susceptible to burnout effects on clinical reasoning, which may indicate that residents may need both cognitive and emotional support to improve quality of life and to optimize performance and learning. These results inform our understanding of mental stress, cognitive control as well as cognitive load theory.

Ordering patterns for laboratory and radiology tests by students from different undergraduate medical curricula

BACKGROUND

The overuse of laboratory tests and radiology imaging and their possible hazards to patients and the health care system is observed with growing concern in the medical community. With this study the authors wished to determine whether ordering patterns for laboratory and radiology tests by medical students close to their graduation are related to undergraduate training.

METHODS

We developed an assessment for near graduates in the setting of a resident's daily routine including a consultation hour with five simulated patients, three hours for patient work up with simulated distracting tasks, and thirty minutes for reporting of patient management to a supervisor. In 2011, 60 students participated in this assessment: 30 from a vertically integrated (VI) curriculum (Utrecht, The Netherlands) and 30 from a traditional, non-VI curriculum (Hamburg, Germany). We assessed and compared the number of laboratory and radiology requests and correlated the results with the scores participants received from their supervisors for the facet of competence "scientifically and empirically grounded method of working".

RESULTS

Students from a VI curriculum used significantly (p < .01) less total laboratory requests (N = 283 versus N = 466) which correlated with their scores for a "scientifically and empirically grounded method of working" (Pearson's r = .572). A significantly (p < .01) higher number of radiology imaging was ordered with a large effect size (V = .618) by near graduates from a non-VI curriculum (N = 156 versus N = 97) even when this was not supporting the diagnostic process.

CONCLUSION

The focused ordering patterns from VI students might be a result of their early exposure to the clinical environment and a different approach to clinical decision making during their undergraduate education which further studies should address in greater detail.

A systematic approach to clinical reasoning in psychiatry

OBJECTIVE

Clinical reasoning in psychiatry may be considered to be more challenging than in other branches of medicine because of its highly subjective nature. The literature on systematic approaches to the teaching of clinical reasoning in psychiatry is lacking, and we propose an approach that may assist educators and learners.

METHOD

A systematic approach with a theoretical underpinning in logical inferences will be proposed as a teaching and learning tool.

CONCLUSION

This paper complements our previous paper on psychiatric case formulation and expands our model of a theoretical framework for diagnostic reasoning and case formulation in psychiatry. Our approach also serves as a tool to assist in integrating the diverse clinical knowledge base in psychiatry.

Clinical reasoning for the infectious disease specialist: a primer to recognize cognitive biases

Infectious disease specialists are frequently consulted for diagnostic and therapeutic advice on challenging cases. When evaluating patients, the infectious disease specialist is well positioned to offer an appropriate diagnostic approach but is also at risk of not recognizing the correct diagnosis for a variety of reasons. We believe it is important to provide infectious disease specialists and trainees with a fundamental understanding of diagnostic errors, clinical reasoning, and cognitive biases. We present 2 cases demonstrating common cognitive biases leading to diagnostic errors, and we reflect on strategies that may aid in their prevention. We hope to provide knowledge and tools that may help prevent diagnostic errors in the future.

How is clinical reasoning developed, maintained, and objectively assessed? Views from expert internists and internal medicine interns

INTRODUCTION

There is limited understanding of how clinical reasoning is developed, maintained, and objectively assessed. Using the theoretical lens of deliberate practice, we explored physicians' views on clinical reasoning. We compared responses from internists (faculty) and internal medicine interns, to identify potential qualitative and/or quantitative differences in how clinical reasoning is developed and maintained.

METHODS

Participants' free-text comments regarding how clinical reasoning is developed, maintained, and objectively assessed were analyzed. Three investigators coded responses using a constant-comparative, grounded theory approach. We also compared the frequencies of each theme between the 2 groups.

RESULTS

Twenty-two faculty and 17 interns participated in this study. Faculty and intern themes for how clinical reasoning is developed, maintained, and objectively assessed were similar, but quantitative and qualitative differences emerged. Interrater reliability of themes was high (overall kappa: 0.92; range: 0.88-0.98). Only experts (faculty) mentioned the value of teaching for development and maintenance of clinical reasoning. Interns focused on knowledge acquisition activities and use of online resources. Experts and intern participants both struggled with how to best measure clinical reasoning; direct observation was rarely mentioned as a strategy.

DISCUSSION

Consistent with our theoretical expectations, we found quantitative and qualitative differences in participants' responses, which have implications for teaching and assessment of clinical reasoning. By capturing the types of activities and their relative frequencies within and between these groups, this work adds to the deliberate practice literature.

System 3 diagnostic process: the lateral approach

The process of obtaining diagnosis is described as a dual-process model, including the intuitive process, and the analytical process. The similarity between the two systems is that they both infer a diagnosis from patient-derived information. Here we present another process by which to elicit the diagnosis: asking direct questions of the patient themselves, such as “What do you think is the cause?” or “What do you suspect is wrong?” This simple method would enable us to elicit pivotal information for diagnosis. Asking patients direct questions allows them to think about the cause of their own problem and suggest their own diagnosis. This method of reasoning is completely different from the two above-mentioned systems and may represent a third approach. We highlight this third process as an important strategy, thereby using this third effective method of inquiry to facilitate quick and effective diagnosis in conjunction with former two systems.

Virtual patients design and its effect on clinical reasoning and student experience: a protocol for a randomised factorial multi-centre study

BACKGROUND

Virtual Patients (VPs) are web-based representations of realistic clinical cases. They are proposed as being an optimal method for teaching clinical reasoning skills. International standards exist which define precisely what constitutes a VP. There are multiple design possibilities for VPs, however there is little formal evidence to support individual design features. The purpose of this trial is to explore the effect of two different potentially important design features on clinical reasoning skills and the student experience. These are the branching case pathways (present or absent) and structured clinical reasoning feedback (present or absent).

METHODS/DESIGN

This is a multi-centre randomised 2 x 2 factorial design study evaluating two independent variables of VP design, branching (present or absent), and structured clinical reasoning feedback (present or absent).The study will be carried out in medical student volunteers in one year group from three university medical schools in the United Kingdom, Warwick, Keele and Birmingham. There are four core musculoskeletal topics. Each case can be designed in four different ways, equating to 16 VPs required for the research. Students will be randomised to four groups, completing the four VP topics in the same order, but with each group exposed to a different VP design sequentially. All students will be exposed to the four designs. Primary outcomes are performance for each case design in a standardized fifteen item clinical reasoning assessment, integrated into each VP, which is identical for each topic. Additionally a 15-item self-reported evaluation is completed for each VP, based on a widely used EViP tool. Student patterns of use of the VPs will be recorded.In one centre, formative clinical and examination performance will be recorded, along with a self reported pre and post-intervention reasoning score, the DTI. Our power calculations indicate a sample size of 112 is required for both primary outcomes.

DISCUSSION

This trial will provide robust evidence to support the effectiveness of different designs of virtual patients, based on student performance and evaluation. The cases and all learning materials will be open access and available on a Creative Commons Attribution-Share-Alike license.

A comprehensive test of clinical reasoning for medical students: An olympiad experience in Iran

BACKGROUND

Although some tests for clinical reasoning assessment are now available, the theories of medical expertise have not played a major role in this filed. In this paper, illness script theory was chose as a theoretical framework and contemporary clinical reasoning tests were put together based on this theoretical model.

MATERIALS AND METHODS

This paper is a qualitative study performed with an action research approach. This style of research is performed in a context where authorities focus on promoting their organizations' performance and is carried out in the form of teamwork called participatory research.

RESULTS

Results are presented in four parts as basic concepts, clinical reasoning assessment, test framework, and scoring.

CONCLUSION

we concluded that no single test could thoroughly assess clinical reasoning competency, and therefore a battery of clinical reasoning tests is needed. This battery should cover all three parts of clinical reasoning process: script activation, selection and verification. In addition, not only both analytical and non-analytical reasoning, but also both diagnostic and management reasoning should evenly take into consideration in this battery. This paper explains the process of designing and implementing the battery of clinical reasoning in the Olympiad for medical sciences students through an action research.

Identifying early warning signs for diagnostic errors in primary care: a qualitative study

OBJECTIVE

We investigate the mechanisms of diagnostic error in primary care consultations to detect warning signs for possible error. We aim to identify places in the diagnostic reasoning process associated with major risk indicators.

DESIGN

A qualitative study using semistructured interviews with open-ended questions.

SETTING

A 2-month study in primary care conducted in Oxfordshire, UK.

PARTICIPANTS

We approached about 25 experienced general practitioners by email or word of mouth, 15 volunteered for the interviews and were available at a convenient time.

INTERVENTION

Interview transcripts provided 45 cases of error. Three researchers searched these independently for underlying themes in relation to our conceptual framework.

OUTCOME MEASURES

Locating steps in the diagnostic reasoning process associated with major risk of error and detecting warning signs that can alert clinicians to increased risk of error.

RESULTS

Initiation and closure of the cognitive process are most exposed to risk of error. Cognitive biases developed early in the process lead to errors at the end. These warning signs can be used to alert clinicians to the increased risk of diagnostic error. Ignoring red flags or critical cues was related to processes being biased through the initial frame, but equally well, it could be explained by knowledge gaps.

CONCLUSIONS

Cognitive biases developed at the initial framing of the problem relate to errors at the end of the process. We refer to these biases as warning signs that can alert clinicians to the increased risk of diagnostic error. We conclude that lack of knowledge is likely to be an important factor in diagnostic error. Reducing diagnostic errors in primary care should focus on early and systematic recognition of errors including near misses, and a continuing professional development environment that promotes reflection in action to highlight possible causes of process bias and of knowledge gaps.

A Cardiopulmonary Instructor's Perspective on a Standardized Patient Experience: Implications for Cardiopulmonary Physical Therapy Education

PURPOSE

Standardized patients (SP) in Doctor of Physical Therapy (DPT) curricula are increasingly used for students to practice developing clinical reasoning, communication, and professional skills in an authentic learning environment. The purposes of this article are to: (1) describe an instructional model that synthesized SPs, Internet-based communities of practice, and reflection to teach clinical reasoning in DPT students; and (2) a cardiovascular and pulmonary physical therapy (CPPT) instructor's perspective on the educational process and student clinical skill development.

SUMMARY OF KEY POINTS

The model, employed in a course: "Integrative Physical Therapy Practice," enabled the instructor to document student clinical performance and reasoning during an SP interaction. For students, clinical reasoning was illuminated through the model's assessment process. Data collected through the assessment process provided important feedback to the instructor on classroom instructional effectiveness.

CONCLUSIONS

Examination of student learning experiences enabled the instructor to consider: (1) key aspects of examination and management for persons with cardiovascular or pulmonary disorders, (2) methods for visualizing clinical reasoning, (3) the impact of teaching on student learning, and (4) strategies for teaching CPPT. More research is indicated to investigate pedagogy for the development of clinical reasoning in DPT students.

Evaluation of clinical reasoning in basic emergencies using a script concordance test

OBJECTIVES

To develop and assess the reliability of a script concordance test (SCT) to evaluate pharmacy students' clinical reasoning when facing basic emergency situations.

DESIGN

A first aid course was designed that consisted of 8 weekly instructional sessions (4 on internal medicine, including life threatening situations; 2 on pediatrics; and 2 on trauma) in which the instructor presented case studies in a small-group format. In the first and final sessions of the course, a practice SCT was administered to familiarize students with the test format.

ASSESSMENT

A 66-question SCT examination was administered to the 68 third-year pharmacy students enrolled in the first aid course. The students' mean score was 68.5% ± 9.8% and panel members' mean score was 86.5% ± 4.2%. Twenty students were selected randomly to complete a course survey and 85% indicated they were satisfied with using the SCT.

CONCLUSIONS

A first aid SCT was found to be both a practical and reliable testing instrument for assessing the clinical reasoning of pharmacy students in basic emergency situations.

A student-led course in clinical reasoning in the core curriculum

Objectives

There is growing evidence for the value of several forms of peer teaching in medical education. Little is known about the feasibility of such an approach in courses of clinical reasoning. The University Medical Center Utrecht offers a clinical reasoning course for first and second year students which previously had been occasionally led by sixth year, i.e. near-peer students. We evaluated a version of this course, fully delivered by final year students.

Methods

In 2008-2009 this highly structured mandatory clinical reasoning course for second year medical students was fully tutored by final year medical students, as part of a teacher training course in their core curriculum. Routine evaluations before and after introducing near-peers as tutors were compared, a focused questionnaire survey was conducted, as well as an interview with a group of students to evaluate the new format.

Results

There was no difference in the ratings of the course before and after the introduction of the new format. In general, second year students are satisfied with the near-peer teachers. Strong points mentioned are their high motivation, involvement, enthusiasm, adjustment of cognitive level of teaching to the recipient students and stimulating skills.

Conclusions

Although our study cannot provide evidence for differential learning effects, the evaluation of our final year student led clinical reasoning course shows encouraging results.

Promoting the self-regulation of clinical reasoning skills in nursing students

Aim:

The purpose of this paper is to describe the research surrounding the theories and models the authors united to describe the essential components of clinical reasoning in nursing practice education. The research was conducted with nursing students in health care settings through the application of teaching and learning strategies with the Self-Regulated Learning Model (SRL) and the Outcome-Present-State-Test (OPT) Model of Reflective Clinical Reasoning. Standardized nursing languages provided the content and clinical vocabulary for the clinical reasoning task.

Materials and Methods:

This descriptive study described the application of the OPT model of clinical reasoning, use of nursing language content, and reflective journals based on the SRL model with 66 undergraduate nursing students over an 8 month period of time. The study tested the idea that self-regulation of clinical reasoning skills can be developed using self-regulation theory and the OPT model.

Results:

This research supports a framework for effective teaching and learning methods to promote and document learner progress in mastering clinical reasoning skills. Self-regulated Learning strategies coupled with the OPT model suggest benefits of self-observation and self-monitoring during clinical reasoning activities, and pinpoints where guidance is needed for the development of cognitive and metacognitive awareness.

Recommendations and Conclusions:

Thinking and reasoning about the complexities of patient care needs requires attention to the content, processes and outcomes that make a nursing care difference. These principles and concepts are valuable to clinical decision making for nurses globally as they deal with local, regional, national and international health care issues.

Chronic fatigue: is it endocrinology?

Fatigue and stress-related illnesses often become diagnoses of exclusion after extensive investigation. 'Tired all the time' is a frequent reason for referral to the endocrine clinic, the implicit question being--is there a subtle endocrine pathology contributing to the patient's symptoms? Often initial assessment suggests not but there are no clear data to address the question of whether overt pathology will develop in the future. This study observed outcomes after five years in 101 consecutive and unselected referrals to secondary care for 'fatigue?cause', where initial assessment did not suggest treatable endocrine pathology. The findings suggest that the clinical diagnosis of fatigue, based on history and tests to exclude anaemia, hypothyroidism and diabetes, is secure: these patients do not subsequently demonstrate excess morbidity and mortality, and their presenting symptoms are not early features of significant endocrine pathology.

Brief report: beyond clinical experience: features of data collection and interpretation that contribute to diagnostic accuracy

BACKGROUND

Clinical experience, features of data collection process, or both, affect diagnostic accuracy, but their respective role is unclear. OBJECTIVE, DESIGN: Prospective, observational study, to determine the respective contribution of clinical experience and data collection features to diagnostic accuracy.

METHODS

Six Internists, 6 second year internal medicine residents, and 6 senior medical students worked up the same 7 cases with a standardized patient. Each encounter was audiotaped and immediately assessed by the subjects who indicated the reasons underlying their data collection. We analyzed the encounters according to diagnostic accuracy, information collected, organ systems explored, diagnoses evaluated, and final decisions made, and we determined predictors of diagnostic accuracy by logistic regression models.

RESULTS

Several features significantly predicted diagnostic accuracy after correction for clinical experience: early exploration of correct diagnosis (odds ratio [OR] 24.35) or of relevant diagnostic hypotheses (OR 2.22) to frame clinical data collection, larger number of diagnostic hypotheses evaluated (OR 1.08), and collection of relevant clinical data (OR 1.19).

CONCLUSION

Some features of data collection and interpretation are related to diagnostic accuracy beyond clinical experience and should be explicitly included in clinical training and modeled by clinical teachers. Thoroughness in data collection should not be considered a privileged way to diagnostic success.

Instructional model to teach clinically relevant medicinal chemistry

The relevance of medicinal chemistry to pharmacy practice has been questioned by many pharmacy educators as more emphasis has been placed on linking clinical knowledge and practice to pharmacy student educational outcomes. Faculty teaching in medicinal chemistry and other biomedical and pharmaceutical science courses have embraced this challenge. Various teaching methods and approaches within medicinal chemistry that emphasize application of this knowledge have been sought to improve the usefulness of this scientific discipline to the future careers of students. The newly revised ACPE guidelines and standards have reemphasized the role of the sciences in the curriculum. With this mandate, it is essential that all science faculty members adjust the way they teach to meet the new desired outcomes for pharmacy graduates. This manuscript describes an instructional model for teaching medicinal chemistry explicitly designed to meet these outcomes. A process of collaboration between experienced pharmacy faculty scholars was used to derive this approach. Pedagogy for cognitive and affective learning was incorporated. A case study using a representative drug class is presented to illustrate this model.

Teaching medical students the important connection between communication and clinical reasoning

BACKGROUND

Medical students are rarely taught how to integrate communication and clinical reasoning. Not understanding the relation between these skills may lead students to undervalue the connection between psychosocial and biomedical aspects of patient care.

OBJECTIVE

To improve medical students' communication and clinical reasoning and their appreciation of how these skills interrelate in medical practice.

DESIGN

In 2003, we conducted a randomized trial of a curricular intervention at Johns Hopkins University School of Medicine. In a 6-week course, participants learned communication and clinical reasoning skills in an integrative fashion using small group exercises with role-play, reflection and feedback through a structured iterative reflective process.

PARTICIPANTS

Second-year medical students.

MEASUREMENTS

All students interviewed standardized patients who evaluated their communication skills in establishing rapport, data gathering and patient education/counseling on a 5-point scale (1=poor; 5=excellent). We assessed clinical reasoning through the number of correct problems listed and differential diagnoses generated and the Diagnostic Thinking Inventory. Students rated the importance of learning these skills in an integrated fashion.

RESULTS

Standardized patients rated curricular students more favorably in establishing rapport (4.1 vs 3.9; P=.05). Curricular participants listed more psychosocial history items on their problem lists (65% of curricular students listing > or =1 item vs 44% of controls; P=.008). Groups did not differ significantly in other communication or clinical reasoning measures. Ninety-five percent of participants rated the integration of these skills as important.

CONCLUSIONS

Intervention students performed better in certain communication and clinical reasoning skills. These students recognized the importance of biomedical and psychosocial issues in patient care. Educators may wish to teach the integration of these skills early in medical training.

Preventing errors in clinical practice: a call for self-awareness

While ascribing medical errors primarily to systems factors can free clinicians from individual blame, there are elements of medical errors that can and should be attributed to individual factors. These factors are related less commonly to lack of knowledge and skill than to the inability to apply the clinician's abilities to situations under certain circumstances. In concert with efforts to improve health care systems, refining physicians' emotional and cognitive capacities might also prevent many errors. In general, physicians have the sensation of making a mistake because of the interference of emotional elements. We propose a so-called rational-emotive model that emphasizes 2 factors in error causation: (1) difficulty in reframing the first hypothesis that goes to the physician's mind in an automatic way, and (2) premature closure of the clinical act to avoid confronting inconsistencies, low-level decision rules, and emotions. We propose a teaching strategy based on developing the physician's insight and self-awareness to detect the inappropriate use of low-level decision rules, as well as detecting the factors that limit a physician's capacity to tolerate the tension of uncertainty and ambiguity. Emotional self-awareness and self-regulation of attention can be consciously cultivated as habits to help physicians function better in clinical situations.
