I corrected myself to say 5-10k in the US and Canada, not just the US. Tens of thousands was way off.
Best data I can find is that about 20% of physicians working in the ED are not EM-trained, and of those 20%, 60% are IM or FM. (Honestly not sure what specialty the other 40% are. What other specialties are practicing in the ED...general surgery? general peds?). Anyways, 44,000 physicians in the ED times 20% non-EM times 60% of those IM or FM =
5,300 FM or IM doctors practicing in the ED in the US. Now, some of those doctors are only going to practice in the ED, especially these days as there is more and more competition for jobs from EM residency grads. But, some are definitely going to do both ED and primary care.
I also intentionally mentioned the US
and Canada together being 5-10k (US FM residency is recognized in both countries with no extra exams).
There are 43,000 FPs in Canada and 14% percent of them practice in
very rural areas. In the best study on the subject "rural" is defined as "outside the commuting zone of centres with populations of 10,000 or more."
Here is the important part from the study:
- 53% of rural FPs provide services in community hospitals vs. 19% of urban FPs
- 49% of rural FPs provide services in emergency departments vs. 13% of urban FPs
- 34% of rural FPs provide services in nursing homes vs. 13% of urban FPs
- 31% of rural FPs provide services in community health centres vs. 12% of urban FPs
So 43,000 FPs * 14% * 49% = 2,950 doctors doing both EM work and primary care, because I can guarantee that these doctors have to do both in a rural setting. The number of FP's doing both ED work and primary care work in Canada is at least a few thousand higher because the definition of rural was narrow in this study. It is more common than not for FPs in cities of 10k-100k to do both ED and primary care work. Doctors in these size cities make up another 12% of FPs in Canada, and with a very conservative 1/3 doing ED work, that is another 1,700 for
a total in Canada of 4,652, although this number is likely significantly higher.
