A med/peds resident told me that she believed that most med/peds residents have approximately the same numbers (grades, board scores, LOR's) as straight medicine residents. On a whole, med peds is more competetive then medicine residencies since most of the institutions that offer med/peds are academic centers which are more competetive then community programs. There are still some med/peds programs that are community programs, some of these have difficulty filling every year and are fairly easy to match into, but I think that it's kind of silly to go to a community program to do med peds since the combined residency is mostly meant for people who want to do academics/fellowships. I would just base your level of competetiveness for a program on how competetive you think that you are for their medicine or peds program individually. For most programs, their pediatrics program is less competetive then their medicine program too. There are fewer spots for med/peds (3-5 spots at most places) then medicine (20-40), but there are also fewer applicants, and I don't think that too many "top" or competetive students go for med/peds, so I think that it mostly all even outs so that roughly the same type of applicants get into med/peds as medicine.
