“What of attempts to improve skin cancer diagnostic skills in primary care, or to develop GP specialists as seen in Australia or the UK? There are various points to make here, and perhaps a lot of wishful thinking about how the problem could be solved if only ‘GPs’ knew more about this or that subdomain of medical knowledge. In truth, such blandishments, must be frustrating to many GPs: there are only so many hours in the day. There are studies showing that it is possible to improve diagnostic skills over the short term following organised tuition (cited in Rees (16)). To find anything else would of course be surprising: if we expose intelligent people to formal tuition or learning, we expect short-term performance to improve. But, the critical point is whether this improvement is maintained, and what aspects of performance suffer because they have been replaced by training in another domain (16). There is no free lunch. If we run a course on skin cancer, then the rheumatologists, cardiologists etc. will all want to run courses. And much of what we know about such one off tuition is that in the absence of consolidation and feedback, the benefits are short lived only. How many of us remember all the history and geography we learned at school?” Here.
