I'll speak from my experience as a 2nd yr.
How many residents per year?
This will depend on how many active attendings there are as well as how the program is structured. You want enough cases where residents are kept busy most of the time but not sitting around doing nothing during slow weeks. At my program, we have the ability to pull residents from off service rotations during busy weeks. Podiatry comes first.
How many active attendings?
Depends on how active. My program has 8 core attendings who practice full scope Podiatry. Some operate 2 times per week. We have 2 residents each month available for cases. Each day should have atleast as many attendings operating as residents. Obviously I'm talking about active attendings with 3-5 cases per day.
What percentage of time would be spent in the OR? Clinic? Wound center? Dedicated research time?
PGY-1 should be in OR as much as possible. They should be exposed to all aspects of Podiatry from hammertoes to pilons. Obviously start off with simpler cases then by the end of the year should have performed or actively assisted (not just retracting or closing) in all types of cases. This will prepare them for PGY-2.
PGY-2 should be the work horse of the program. Performing almost all cases skin to skin from recon to trauma to elective cases. This leaves PGY-3 residents available for rare or complex cases of their choosing.
PGY-3 should be able to cherry pick the rare and complex as they choose. TARs, rare trauma, complex recon, etc. They should also be available for clinic. I have no experience with resident run clinics but visions of county type hospital clinics come to mind and IMO that would not be ideal. Clinic experience is meant to prepare for "real life" practice. Obviously full scope podiatry would be ideal. Clinic is where residents learn how to talk to patients, perform office procedures, and learn how to run an office, billing, etc.
Mix of pathology (inpatient vs outpatient and forefoot vs rearfoot vs ankle).
Like Anklebreaker mentioned above, Rearfoot/Ankle should be about 70%. If you make a list of all procedures in the foot and ankle, I would guess percentages in each anatomical region would be close to 30% forefoot: 70% rearfoot/ankle. Your educations and experience should reflect that.
Anything else that you would find important in designing your ideal program, assuming you couldn't choose the hospital or the location?
Hospital based for sure. No running around to different surgery centers. A couple are probably fine but like Anklebreaker said, driving all day is a waste of time. For podiatry, I think community hospitals are typically better than university. This way you aren't competing for foot and ankle cases. As a student I rotated at programs with ortho and podiatry programs. Terrible for podiatry. Typically ortho gets called 1st and podiatry gets dumped on. I once met an ortho resident that bragged about stealing cases from podiatry. Another program I met an ortho attending that was speaking on the phone saying "All extremity cases should go to ortho, not podiatry. My residents are just being lazy giving it to podiatry." All in front of me, a student, and the podiatry resident on his service.
My program is a community hospital and all foot and ankle goes to podiatry, not ortho. The hospital also has 1 ortho foot and ankle on staff and he has recently been able to take call with Podiatry. Another plus is no ortho residents. So when the ortho attendings do get the random ankle fracture, they welcome the podiatry residents to help out. Being the only residents does wonders for the Ortho relationship. They see the cases we are doing, they see our training, they see our work. For example, 2 weeks ago I did a skin to skin pilon with one of the ortho attendings...I've worked with him only once previously.
ldsrmdude, good luck with opening a program. I hope you are successful. Podiatry needs more quality programs.
