Despite derailments or provocations from obvious quarters, occasionally an attempt at a gotcha raises something with a kernel of interest.
A few pages back there was a MNW-PFL back and forth regarding standards and the GMC, and as a strawman this was ignored. However, the GMC acknowledges that "differences between medical schools exist and that it is ‘inevitable’ that this variation can influence a graduate’s ‘interests, abilities and career progression" (Ellis BMJ Open 2022, GMC quote, my bold here and below). Ellis goes on to cite "significant variation in preparedness for practice, progression through Annual Reviews of Competency Progression in UK training programmes and fitness to practice sanctions according to the medical school of primary qualification," and "significant differences in the performance of graduates from different medical schools on high-stakes postgraduate examinations" specifically MRCP, MRCS, MRCOG, MRCP and FRCA.
The GMC lists 52 institutions that currently, or will shortly, award medical degrees. In many cases it will be impossible for patients to know where clinicians really qualified, graduates of the University of Cumbria will be awarded their degrees by Imperial College London, for example.
There is already significant heterogeneity in the quality of medical schools and medical graduates, and expansion is unavoidably at the lower end. This again from the GMC (workforce report):
"Due to increases in medical school places, the decrease in the proportion of the workforce who are UK graduates may slow or come to a stop. It could even start growing again. Regardless, each UK country will still need large numbers of non-UK graduates until 2036."
If Royal College filters are stable, UK medicine is a leaky bucket into which an increasingly leaky material is being poured.
