As long as our training is highly variable (uniform 3yrs in length only), we'll have these issues. Some of us do a lot of surgery in residency, many don't... some in academic hospitals, some not... some residencies pass Abfas nearly 100%, some don't.
Podiatry expanded real fast, didn't have the training spots to support it... now fellowships take cases out of residencies. This is the natural outcome: even podiatrists don't agree on what DPMs can uniformly do (since training and competence are not uniform).
As long as ppl stay in their lane,do good work, pass boards appropriate to what they do, we'll have few problems with patient outcomes.
I have seen plenty of bad surgical outcomes by podiatrists... but the truly terrible outcomes have been medical ("clearing" asa3 for surgery, admitting sick ppl, messing up meds, trying to treat skin/bone cancers, tryingto treat DVT, etc... basically not asking for help when they should).
