Medical education over time — are we keeping up?
Medical practices — including the use of plants as healing agents, surgery for wounded and injured people, and the practice of observation and reasoning regarding disease — have been in effect for many thousands of years. However, medical schools are a more recent phenomenon. Believed to have opened in the 9th century, the Schola Medica Salernitana at Salerno in southern Italy is considered to be the first medical school but officially closed in 1811.1 The University of Bologna’s school of medicine and surgery, established around 1200, is the oldest such school still in existence.2 The first medical school in the United States, the Perelman School of Medicine at the University of Pennsylvania in Philadelphia, opened in 1765, and the Sydney Medical School at the University of Sydney, which opened in 1856, is the oldest in Australia.
In this article, we review the evolution of education in medicine and the challenges that medical schools face today.
Medieval medicine was based on Galen’s theory of humours. It was not until the 18th century that physicians became more scientific, influenced by the scientific revolution with its developments in mathematics, physics, astronomy, biology, anatomy and chemistry. Armed with knowledge, doctors in the mid-19th century, teaching at European medical schools, predominantly taught medical students by delivering didactic lectures and readings with only limited exposure to clinical experiences3 and laboratory work.
Movement towards the modern model of medical education began in the US when Johns Hopkins School of Medicine, Baltimore, opened in 1893. Influenced by German medical schools, Johns Hopkins School of Medicine implemented an educational model consisting of traditional medical knowledge combined with research and extensive laboratory learning, bedside learning at the side of experts, and postgraduate education in the hospital for interns and residents. This educational paradigm became the template for postgraduate clinical education in the 20th century4 in other American medical schools following the 1910 Flexner report.5 Flexner criticised many medical schools as a loose apprenticeship system that lacked defined standards or goals beyond the generation of financial gain. Flexner made recommendations regarding the standard of medical schools in the US and Canada and proposed that medical school training should focus on biomedical sciences together with hands-on clinical training. The report triggered reforms in the standards, organisation and curriculum of North American medical schools and gave rise to modern medical education.5
Over the past century, countless discoveries have led to an explosion of medical knowledge: the development of antibiotics and vaccines; imaging modalities such as ultrasound, computed tomography and magnetic resonance imaging; understanding of data collection for statistical and population health purposes; and new models in genetics and immunology. There is now a focus on reducing harm and improving patient health by applying research methods to help understand what facilitates quality improvement, and basing decisions on evidence-based medicine and the use of patient data. Further, rapid demographic and epidemiological transitions, complex health systems, increasing numbers of patients with chronic conditions and a longer life expectancy require medical students to integrate the rapid growth of knowledge and technologies while also learning about prevention, coordinated care across time and space, teamwork and communication.
Traditional education consisted of transmitting knowledge, skills and standards that were considered to be required in order to practise as a doctor. Students were expected to unquestioningly and obediently receive and believe the information put to them. Teachers were the instruments through which knowledge was communicated and standards of behaviour were enforced.6 This approach dominated medical education until the end of the 19th century, when the education reform movement resulted in the development of progressive educational techniques.7 Many learning theories have been proposed subsequently. What is evident is that adult learning includes transformative learning, which is based on discussing with others the “reasons presented in support of competing interpretations, by critically examining evidence, arguments, and alternative points of view”.8
Given the explosion of knowledge (estimated to be doubling every 3 years), its multiple sources including online, and the increased expectations of society for better health care, what and how do we want medical students and doctors in training to learn? Or are we now at a stage where our expectations of graduating students must change and we need to become increasingly selective as to what is critical to being a safe, competent, patient-centred doctor? With increasing participation of patients in their care, increasing use of improvement science, requirements for accountability, scrutiny, measurement, incentives and markets, medical education is becoming an ever-increasing challenge.
As a result of the rapid changes in today’s knowledge, we need to again move into a new era of education. In 2010, the global independent Commission on the Education of Health Professionals for the 21st Century acknowledged that “fresh health challenges loom”.9 The report also commented that “all health professionals in all countries should be educated to mobilise knowledge and to engage in critical reasoning and ethical conduct so that they are competent to participate in patient- and population-centred health systems as members of locally responsive and globally connected teams”.9
A General Medical Council report10 on the preparedness of United Kingdom medical graduates for practice found that graduates felt unprepared for a range of skills and experiences such as changes in responsibility; workload; multitasking; understanding where to go for help; adopting a holistic understanding of the patient; involving patients in their care; safe and legal prescribing; diagnosing and managing complex clinical conditions; and providing immediate care in medical emergencies. In addition, there were gaps in the preparedness in communication skills such as talking with angry or upset patients and relatives, breaking bad news, communicating with the wider team (including inter-professionally) and handover communication. There was also evidence to suggest that graduates were unprepared for dealing with error and safety incidents and had a lack of understanding of how the clinical environment works.10 Similar results have been reported from graduates from countries outside the UK.11,12 Such concerns about competencies of graduating medical students have been raised for at least two decades, resulting in some changes in medical school curricula and the development of guidelines for training of junior doctors.11
The ability of medical education providers to deliver medical graduates who are skilled and competent has always been challenging. Perhaps greater challenges are experienced today because professional health education has not kept pace with explosion of knowledge, learning styles of 21st century students and dramatic changes in way health care is delivered. There remains a disconnection between medical education and the health care delivery environment,13 as demonstrated by the persisting sense of unpreparedness of medical graduates. The problems in medical education are systemic and include mismatch of competencies to patient and population needs, poor teamwork, persistent gender differences in professions, narrow technical focus without broader contextual understanding, episodic encounters rather than continuous care, predominant hospital orientation when medicine is largely practised in a community setting, imbalances in the professional labour market, and poor leadership to improve health system performance.
To produce skilled and competent doctors, student-centred teaching and innovative curriculum design is needed not only in universities but also in the post-graduation teaching and learning environment. No single, uniform approach can be used to achieve this teaching and learning goal. As knowledge expands faster than our ability to assimilate, apply and teach effectively, adding more material and/or time to any curriculum is not an effective strategy. Fundamental changes are required. If the goal of education is to facilitate students’ autonomous learning and self-expression, and offer adaptable teaching, then a flexible, modern, inclusive, technologically enhanced, student-centred approach, where the student is an active participant in the learning process, is required.
To practise as a doctor today, it is not sufficient to just have knowledge. The Australian Medical Council has developed a thematic framework to ensure that medical programs provide graduates with the knowledge, skills and professional attributes required to practise medicine in the 21st century. The Council’s curriculum domains are:
-
science and scholarship: the medical graduate as scientist and scholar;
-
clinical practice: the medical graduate as practitioner;
-
health and society: the medical graduate as a health advocate; and
-
professionalism and leadership: the medical graduate as a professional and leader.14
By appreciating these domains, it becomes evident that behaviours and attitudes are as important as knowledge and skills. Because communication, handover and medication errors are the leading causes of harm,15 focus needs to increasingly turn to developing interdisciplinary, team-based curriculum units that enable students to learn from different disciplines through a unifying theme.
Today, there are many opportunities for learners to acquire knowledge outside the traditional classroom and textbooks. Sources include the internet, chat rooms and social media. The task for the teacher and learner is how to discriminate between the vast amounts of information and to extract and synthesise the knowledge necessary for clinical and population-based decision making.
With the doubling of medical students and graduates, the advent of safe working hours and the increasing expectation of delivering perfect health care, there has never been a more demanding time to train medical students and training doctors. With the added burden of the massive expansion of knowledge and information outlets, teaching and learning need to be nimble, innovative but structured in their approach to ensure that our graduating and training doctors are safe, patient-centred, effective and efficient.
