locums for pathology is a little different than locums for medicine. the actual process is the same, but the level of skill required to do it is different. let me explain...
as a medicine resident, you would get graded responsibility to the point where you are actually making treatment decisions on your patients, and would be reasonably trained to head out of residency and staff small town ERs and other such "fill-in" locums work. once you finish a pathology residency, i would say it takes about ten years of experience before you are comfortable practicing on your own.
now i understand that all doctors, regardless of their specialty, are learning throughout their lifetime. however, the method of pathology training along with the breadth and depth of field, make this a particularly difficult field to practice "right out of the gates." most trainees struggle and get considerable help from their partners early on, in contrast to clinicians who can function more independently. i know young clinicians will learn from their more senior collegues, but i guarantee that a consensus opinion in pathology is sought after to a much greater degree than in medicine.
so if you are thinking about doing locums for the adventure, or checking out different areas of the country before you settle down, you might want to understand how difficult locums would be for a newbie. the only reason i am going on about this is that i thought about it. but the more i got into pathology, the more i realized how little i knew, and how impossible locums would be. maybe in 30 years when i retire.
