Medicine: A Scholarly Discipline or a Trade?
Competence-Oriented Medical Education
Educational Initiatives Designed to Develop Competence in Individual Patient Care
1. Problem-based Learning
Roughly 80% of US medical schools now provide at least some problem-based learning to their students. Students from problem-based learning schools perform well on standardized tests of knowledge (Kincade, 2005); there is evidence that they may be particularly proficient at making clinical diagnoses, retaining knowledge, integrating basic science concepts into clinical problems, and acquiring up-to-date clinical concepts following graduation (Nandi et al., 2000). Problem-based learning at the residency level also improves self-directed learning behaviours and in-training test scores (Ozuah, Curtis, and Stein, 2001). Students who participate in problem-based learning’s intensive group process demonstrate better interpersonal skills and psychosocial knowledge than their counterparts from traditional programmes (Kincade, 2005; Nandi et al., 2000; Ozuah, Curtis, and Stein, 2001). They may therefore possess more of the specific skills of leadership management, and cooperation needed for executing changes in the current complex environment of practice.
2. Evidence-based Medicine
As it is currently defined, the practice of evidence-based medicine involves systematic and judicious application of the best available research evidence in the clinical care of individual patients and patient groups. Learning rigorous methods for formulating clear, answerable clinical questions, searching the medical literature, and critically appraising research studies are the working-knowledge cornerstones of this discipline. Translating relevant evidence into practice requires learning how to judge the relevance of research information to the problems of individual patients, and applying it to those patients in the context of local practices. Teaching the practice of evidence-based medicine at the undergraduate, graduate, and practitioner level has been shown to improve clinical knowledge, critical appraisal skills, the use of original studies to answer clinical questions, attitudes about the role of evidence, and clinical behaviour. It has proven to be most effective when it is integrated with “bedside” clinical teaching, in contradistinction to its use in classroom settings (Coomarasamy and Khan, 2004; Bradley et al., 2002).
Unfortunately, many pragmatic obstacles – the intimidating amount and complexity of published evidence; lack of confidence that answers to clinical questions are available; inadequate literature searching and appraisal skills; and most importantly, lack of time – interfere with the practice of evidence-based medicine in real-world clinical settings. As a consequence, most clinical questions that come up in daily practice still remain unanswered (Dawes and Sampson, 2003), a major factor in the “pressure drops in the pipeline from the generation of research evidence to its consistent application in clinical decision-making” (Scott, 2007). Learning to use the assistance of clinical librarians, pharmacists, and other “informationists” is therefore becoming an increasingly important, if underutilized, educational strategy in the practice of evidence-based medicine (Shearer, Seymour and Capitani, 2002).
3. Learning to use Clinical Guidelines
Valid, credible clinical guidelines are based on exhaustive review and critical appraisal of the medical literature. Evaluating the quality of clinical guidelines and applying them in practice can therefore serve as important proxies for direct retrieval and use of research information. For these reasons, learning about how best to use clinical guidelines is now considered a legitimate and important element in continuing medical education. Well constructed and precisely worded clinical guidelines help to adapt research evidence to individual patients since they take into account a range of patient characteristics, including comorbidities (Michie and Johnston, 2004). Clinical guidelines and protocols also help to apply evidence from research to specific patients through “forcing functions” such as algorithms, standard order sets, and flow sheets – all invitations to attend to the modification of process and habit. Despite many barriers to their validity, generalizability, and effectiveness, the use of clinical guidelines and protocols has been shown to be capable of making practice more reliable and more consistent with evidence from research (Grimshaw et al., 2004).
Initiatives Designed to Develop Competence in System Change
A wide variety of initiatives now allow learners to acquire the “how to” knowledge they need to improve dysfunctional care systems. Some of these initiatives are broadly conceived and provide learners with know-how across the entire scope of improvement-related knowledge systems (Batalden and Davidoff, 2007b) as they grapple with real-world problems in health care delivery systems. Other initiatives are targeted much more narrowly, allowing learners to develop specific skills. All of these efforts are now supported by a substantial published literature in the rapidly evolving “science of improvement,” including a growing number of discipline-specific journals (for example, the Joint Commission Journal on Quality and Patient Safety and Quality and Safety in Health Care), textbooks, and monographs. Importantly, some highly effective experiential learning in these areas is taking place outside academic centers.
1. Initiatives that are Broad in Scope
In 2002 Gould and colleagues (Gould et al., 2002) reported on an innovative clinical clerkship for second-year medical students. Working in community-based practices, the students who participated in this clerkship were involved in designing and implementing a plan to improve the care of a population of diabetic patients. They first formulated a clear improvement aim for the target population, then characterized the patient group by collecting baseline data on over 500 patients. They designed and helped to implement an improvement intervention that fit in with the nature of the participating practices and worked to assure that the intended changes were put into practice. Follow-up measurements at six months revealed that the proportion of office visits with foot examinations had increased from 51% to 70%, the proportion with eye examinations had risen from 27% to 38%, and the patients’ mean glycosylated hemoglobin level had decreased from 7.7% to 7.2%, all statistically significant changes. In a formal assessment of the experience, the participating students acknowledged the benefits of outcomes management in clinical practice – as well as the tedium of medical records abstraction.
As in all traditional clinical clerkships, the students in this new clerkship were engaged in experiential learning – learning by doing – by taking care of real patients in real practices, and what they acquired in the process was working knowledge or know-how. What was different was that rather than simply learning how to deliver care, students were learning how to improve it – that is, to consciously and systematically bring the performance of a portion of the health care system closer to what the available scientific evidence says it can and should be (Institute of Medicine, 2001). Many similar broad, system-oriented initiatives in education have now been reported. A recent systematic review concluded that many of those initiatives have been effective in improving knowledge about quality improvement, attitudes toward health systems, and participation in quality improvement activities (Boonyasai et al., 2007). The review also noted, however, that learners’ knowledge about improvement improved more than clinical outcomes, clinical benefits did not occur when learner behaviours did not change, and the use of adult learning principles did not improve educational outcomes. At the same time, the review did find that clinical outcomes were more likely to improve when the teaching methods were appropriate for experiential learning and included, for example, the provision of quality improvement tools, individualized coaching, and learners’ involvement in iterative tests of change (Batalden and Davidoff, 2007a).
2. Narrowly Focused Programmes
Other system-related improvement-oriented learning has been more narrowly focused. For example, teamwork training, based largely on the “crew resource management” training that has helped make aviation increasingly safe, has been introduced in a number of educational settings. Designed to develop high-level skills of both leadership and “followership,” these programmes appear to be particularly valuable for providers in areas (for example, surgery and emergency medicine) characterized by extreme complexity, major time pressure, rapidly changing information load, as well as high ambiguity, workload, and risk (Thomas, Sexton and Helmreich, 2004). Similarly, as part of the effort to prevent the failures in communication that account for a large proportion of adverse patient events, many providers are being trained in the use of structured communication tools such as the SBAR (situation-background-assessment-recommendation), situation briefing model, and other related techniques (Leonard, Graham and Bonacum, 2004).
Factors Affecting the Development of Performance-Oriented Education Initiatives
Successful development of any educational initiative depends at least in part on the ability to assess its impact. Although the assessment of professional competence and performance continues to present difficult challenges (Carracio et al., 2002; Epstein and Hundert, 2002), a variety of instruments are now available that provide reasonably reliable process measures of individual clinical performance (Durning et al., 2002; Peabody, Luck and Glassman, 2004; Branch, 2005; Toolbox of assessment methods, 2005). Learning portfolios – collections of materials made by learners that record key elements in their training and careers – appear to be uniquely suitable for reflective observation on performance (Challis, 1999). An example of particular interest is the PCDiary, a national electronic learning portfolio into which nearly all Canadian physicians now regularly enter “learning items” (Dornan, Carroll and Parboosingh, 2002). It allows physicians to compare their learning needs and practices with those of their peers. Analysis of aggregated data from PCDiary has revealed that reading the medical literature is itself the most frequent stimulus for further learning. Reviewing the management of more than one patient emerges as the strongest determinant of a commitment to make a change in practice (Campbell et al., 1999).
Momentum generated by the growing experience with improvement efforts, and the increasing effectiveness of those efforts, will help to drive expansion of performance-oriented learning programmes at all levels of medical education. Perhaps more important, these programmes are no longer optional in the US. The Accreditation Council for Graduate Medical Education (ACGME) now includes “practice-based learning and improvement” (which focuses on individual patient care) and “systems-based practice” (which focuses on care systems) among the six competencies that residents in all specialties are expected to acquire (Batalden et al., 2002). Programme directors throughout the USA are actively developing learning experiences designed specifically for that purpose. The 24 members of the American Board of Medical Specialties (ABMS) have recently adopted Maintenance of Certification requirements built on the same six competencies and will require evidence from each certified mid-career physician that they are being exercised (American Board of Medical Specialties, Evanston, IL., 2006).
Of course, only time will tell whether performance-oriented learning initiatives really represent a major and enduring shift in medical education or will prove to be yet another in the long history of failed educational reforms (Carracio et al., 2002; Ludmerer, 1985; Papa and Harasym, 1999). It is already clear, however, that their future development faces many obstacles: the prevailing push of clinicians toward piece-work productivity diminishes the time available for reflection; individualized coaching is more expensive and time-consuming for faculty than lecturing, and relatively few faculty have been trained to be expert coaches; and confronting performance shortcomings can be painful. Moreover, medical faculty generally have little experience in rigorously evaluating the clinical performance of the systems in which they work; it is hard to build evidence-based medicine into teaching unless it has been solidly incorporated into the faculty’s own clinical practices (Richardson, 2005); and medicine’s autonomy-driven culture can make it difficult for both teachers and learners to adopt the kind of shared decision-making required in high reliability organizations.
The Implications of Performance-Oriented Learning Initiatives for Medicine and Medical Education
Successful improvement in performance at both the individual and system level will demand continuing discoveries of new ways to understand and influence the complex social systems in which improvement takes place (Batalden and Davidoff, 2007a; Boonyasai et al., 2007), as well as a progressive increase in understanding the nature of experiential learning (Schon, 1987). At the same time, these challenges create important research and academic opportunities for medical faculty which, over time, can help to legitimize the epistemology of improvement in academic settings. Those opportunities may, in turn, enable improvement science to command new sources of funding, venues for publication, and criteria for academic promotion, thus strengthening the teaching infrastructure and catalyzing a further evolution of the role of experiential learning in medicine.
These changes need not dilute or diminish the importance of the traditional scientific base or of conceptual learning in medicine and medical education. On the contrary, since generalizable scientific evidence is an essential element of improvement science, strengthening improvement-oriented experiential learning can only enhance the value of that evidence by linking it more directly and effectively with the process of health care delivery.
