Use of scheme-based problem solving: an evaluation of the implementation and utilization of schemes in a clinical presentation curriculum.

CONTEXT: The University of Calgary has implemented a new curriculum which is organized according to 120 ways in which patients may present to a physician. Students are taught scheme-based problem solving rather than the more typical hypothetico-deductive or search and scan approach to problem resolution. OBJECTIVE: This study sought to determine the extent to which faculty and students were implementing and utilizing scheme-based problem solving. METHOD: All classes taught within the new clinical presentation curriculum were surveyed at the year end. Participants included four classes of first-year students and three classes of second-year students. Using a 5-point scale, students responded to survey items regarding scheme implementation and utilization. RESULTS: Data were analysed using MANOVA (multivariate analysis of variance) and revealed significant differences among classes in both first- and second-year students. Increments in scheme implementation and utilization by instructors and students were observed, although instructors' utilization of schemes lagged behind that of students. A levelling effect to the benefits of schemes for problem solving was also evident. First-year students reported schemes to be very useful for learning and organizing new information. CONCLUSION: Although it has taken time to implement curriculum change, the student response to schemes has been favourable. Faculty development and further generation of pictorial/spatial representations for all schemes, to ensure that all clinical presentations provide pathways that students can use for both learning and problem solving are recommended. Whether students who utilize schemes are more successful problem solvers is not yet known but will be the subject of study as soon as scheme delivery is predominant.

Helping students learn to think like experts when solving clinical problems.

Analysis of problem-solving strategies reveals that although there is no universal, generic problem-solving process, there is a clinical reasoning process that is specific and highly tailored to the complexity of each clinical problem. Research reveals that successful problem solvers must possess comprehensive knowledge, but that the way they organize and understand their knowledge is even more critical. Moreover, using "schemes" for both learning and problem solving provides the advantage of combining the creation of a knowledge structure and a search-and-retrieval strategy into a single operation. (A "scheme" in this context is a mental categorization of knowledge that includes a particular organized way of understanding and responding to a complex situation.) The implication for medical education is that a comprehensive knowledge domain must be appropriately organized for knowledge mastery, which in turn is essential for clinical problem solving. Problem-solving strategies must be specific for each problem and not based on the assumption of a universal generic process. Consequently, a new taxonomy of medical problems is recommended, along with an altered problem-based learning (PBL) format. The "hypothetico-deductive" strategy traditionally used in PBL should be replaced by scheme-driven search strategies so that students develop a more organized and logical approach to problem solving.

Developing a "clinical presentation" curriculum at the University of Calgary.

Currently, medical curricula are structured according to disciplines, body systems, or clinical problems. Beginning in 1988, the faculty of the University of Calgary Faculty of Medicine (U of C) carefully evaluated the advantages and disadvantages of each of these models in seeking to revise their school's curriculum. However, all three models fell short of a curricular structure based on current knowledge and principles of adult learning, clinical problem solving, community demands, and curriculum management. By 1991, the U of C had formulated a strategic plan for a revised curriculum structure based on the way patients present to physicians, and implementation of this plan has begun. In creating the new curriculum, 120 clinical presentations (e.g., "loss of consciousness/syncope") were defined and each was assigned to an individual or small group of faculty for development based on faculty expertise and interest. Terminal objectives (i.e., "what to do") were defined for each presentation to describe the appropriate clinical behaviors of a graduating physician. Experts developed schemes that outlined how they differentiated one cause (i.e., disease category) from another. The underlying enabling objectives (i.e., knowledge, skills, and attitudes) for reaching the terminal objectives for each clinical presentation were assigned as departmental responsibilities. A new administrative structure evolved in which there is a partnership between a centralized multidisciplinary curriculum committee and the departments. This new competency-based, clinical presentation curriculum is expected to significantly enhance students' development of clinical problem-solving skills and affirms the premise that prudent, continuous updating is essential for improving the quality of medical education.

The effect of structure on attendance in a day-hospital program.

The effects of program structure on patient attendance rates within a day-hospital program were studied. It has been recognized that regular attendance at partial-hospitalization programs is necessary to facilitate improvement in patient skill deficits. In this study, three different program structures were offered in a 40-person day program. Significant differences in attendance rates were achieved.

An evaluation of the clinical problem-solving process using a simulation technique.

Currently, research does not agree as to the extent to which medical content and problem-solving processes underlie clinical problem-solving. The results of research in this area fall into two categories: (1) clinical problem-solving is primarily dependent upon medical content specific within the case, and (2) clinical problem-solving is a skill, or series of skills, which can be applied to all clinical problems. In the study reported in this paper, seventy-one second-year medical students who had completed a 2-year, body-systems oriented curriculum were given an examination designed to measure clinical problem-solving. The results indicated that gathering data on patient history and hypotheses generation were specific skills common to clinical problem-solving, while hypotheses refinement, identification of relevant physical examinations, ordering laboratory investigations and making a diagnosis were case-related.

Educational instruction on a hospital information system for medical students during their surgical rotations.

OBJECTIVE: To evaluate the benefit, for medical students on their surgical rotations, of real-time educational instruction during order entry on a hospital information system. DESIGN: Prospective controlled trial. INTERVENTION: Access to educational information during computerized order entry. SUBJECTS: Medical students in their final year at the University of Calgary. MAIN OUTCOMES: Attainment of the surgery rotation educational objectives, as measured by performance on a multiple-choice examination. METHODS: Before they began their surgical rotations, students at two hospitals took a multiple-choice examination to measure their knowledge of surgery. One hospital had an information system with computerized order entry; students at this hospital had access, while composing orders, to educational material on the system. The other hospital did not have an information system; students there wrote orders on a paper chart. At the end of the rotation, all students took another multiple-choice examination. RESULTS: Of 50 eligible students, 45 agreed to participate in the project, 21 in the treatment group and 24 in the control group. Pre-rotation scores were similar for the two groups (43 percent in the treatment group and 40 percent in the control group; SD, 10 percent). Post-rotation scores were identical for the two groups (65 percent in the treatment group and 65 percent in the control group; SD, 12 percent). A t-test analysis revealed no significant difference in performance on the examinations between the two groups. CONCLUSION: This study did not demonstrate a learning advantage for medical students who have access to educational material on a hospital information system.

Computerized quality-of-life screening in an oncology clinic.

PURPOSE: The purpose of these studies was to assess the feasibility and reliability of computerized quality-of-life screening for patients attending an outpatient breast cancer clinic. The screening program involved a computerized administration of the European Organization for Research and Treatment of cancer QUality of Life Questionnaire (EORTC QLQ-C30). The computer software generated a screening report that clinic staff members used in the clinical encounter to assist in identifying quality-of-life problems. DESCRIPTION OF STUDY: Two studies are reported. In study I, 36 patients and either their nurses or physicians evaluated the feasibility of the screening program using questionnaires developed for this study. In study II, a separate sample of 50 patients completed both the computerized and paper-and-pencil versions of the QLQ-C30 to assess reliability and consistency of responding. RESULTS: The results of study I indicate that the patients found the computerized administration to be an acceptable means of providing staff members with information on day-to-day functioning. Clinic nurses and physicians indicated that the report was useful in identifying problematic quality-of-life domains. The results of study II indicate that the computerized administration is highly correlated with the paper-and-pencil version and has similar internal consistency. Discrepancies in responses were identified, but were at an acceptable level. CLINICAL IMPLICATIONS: The results of these studies indicate that computerized quality-of-life screening is feasible and may provide reliable data for research and quality assurance studies. Staff evaluations suggest that the written report may provide clinic staff members with a tool for identifying quality-of-life concerns in which individual patients are experiencing difficulty. Potential benefit to patients include productive use of waiting room time, greater efficiency in the assessment process, and an improved likelihood that nurses and physicians will recognize and attend to quality-of-life deficits. The valid, reliable, and efficient identification of important patient quality-of-life concerns allows multidisciplinary team members to focus meaningfully their clinical efforts within their respective areas of responsibility.
