No, I do not think they should be paired. Patients who need ID consults at the hospital can be exquisitely sick, on death's doorstep. FM is more suited towards primary prevention and outpatient wellness/followup, rather than ordering IV voriconazole or daptomycin. These physicians need to be trained very well with an internal medicine background, especially as complex issues in nephrology/renal status, for example, are often involved. As for outpatient HIV followup, this may be a possibility for a FP, but resistance patterns, side effects, etc. often cloud the picture. When you get into AIDS, that's a whole different ballgame where patients are susceptible to vastly different conditions. That's also when I would want someone with an internal medicine background treating this patient. You don't see an ID doctor because you have a cold or some random skin infection, any FP can take care of that. Since you are a pre-med, I don't blame you for having this thought, but give it a few years and you will see just how complex the field can be.
