What should I pay off first, $8000 in credit card bills, or $5000 in hospital bills?

I'm graduating this fall from college and I really want to get out of as much bad debt as I possibly can. I anticipate earning approximately $10000 at my summer job and I'm unsure of which debt to pay off. Should I completely pay off the credit card first, the hospital bills first, or a combination of both. Thanks for the help.

Pay off the higher interest debt first, but still making the minimum payments on the rest. By doing this you will establish a good credit rating, or at least improve a bad one.
