The apprentice model of medical education is ingrained in the traditional lore of medical practice, and heuristics like ‘see one, do one, teach one’ are still commonplace.
As with all skills – medical procedures have a learning curve. Some learning curves are longer than others – a hernia repair is not the same in terms of complexity as a coronary artery bypass graft. But all procedures do have a learning curve.
The current editor’s choice in the PMJ (free) – analyses the results of a relatively new technique for assessing hepatic fibrosis in light of the operators experience. Unsurprisingly it shows that there is a learning curve to the technique; accuracy and concordance with a gold standard improves with experience.
The way in which the initial experience of using this technique is gained is through a course developed and delivered by the manufacturers of the product. This course involves theoretical, and practical aspects of the technique, and the opportunity to practice obtaining readings on 3 healthy subjects.
There were a couple of points from the paper which struck me as important for the wider training of clinicians, and medical education as a whole.
The first was that there is a disconnect between the number of scans performed during the course of training supplied by the manufacturer, and the number noted in the study to confer a degree of certainty about the reliability of the result. The difference may not be huge – but the defining of learning curves for practical procedures is an important one in the days of competency based curricula.
However the paper raised my hackles a little bit with regards to another staple feature of modern medical education: the course…
Nowadays it seems impossible to learn any new skill without going on a course – be that a bronchoscopic technique, a surgical knot, or how to perform a fibroscan. Clinical practice with appropriate supervision, it seems is no longer the best way to acquire skills and knowledge, and the separation of training from service which has been lobbied for over time may have come to pass.
But, what this paper shows is that going on ‘the course’ is not the end of the learning curve. As with most skills, learning continues in practice. The manufacturer of the equipment provide a reasonable grounding in how to perform the technique, but not enough, according to this paper, to produce reliable results.
Perhaps this is seen as stating the obvious, but we would do well to remember that knowledge and skills acquired in a classroom do not always confer competence. And for trainers who are responsible for patient safety, and patient care – perhaps a more robust test of confidence is the test of trust – would you trust this person to perform this procedure without supervision on your patient, or your family member (the grandma test)
The separation of clinical practice and training in the minds of trainees is a dangerous road to stroll down. Indeed, if we do not see our wards and clinics as the active training environments that they are, and fail to maximise the educational opportunities which reside there, we do a disservice to our patients.
The increasing reliance on ‘the course’ to provide education can be a convenient way to accelerate learning in a particular field, but if courses are being used to cover core competencies of medical practice, because training posts cannot cover that ground, or provide that supervision – we need to reflect deeply on how educating our juniors and developing their clinical skills and acumen has fallen so far down the agenda that service is now seen as completely divorced from education.
