I don't know about admission stats, but you can try Mark Chalmers the admissions counselors. (firstname.lastname@example.org)
I'm not sure on their focus either. A solid GPA (say above 3.5) will keep you competitive though a low will not cut you out if you have other strengths. Health care experience or a biology background may help, but many members of the class do no have any experience so it will not hurt you either if you're lacking. Basically, as with any college, make sure you have a balanced portfolio. If you have weaknesses, make up for them elsewhere (e.g., if you have a low GPA, try to get some experience/volunteer work in a hospital). Your interview is a time to explain anything and prove you've got what it takes to enter the program.
Best of luck!
