Before you interview, you should learn the demographics of this group or hospital. You should be comfortable with the demographic distribution because that will determine the type of practice you will have or how you will interact with this demographic. Regardless of whether they take care of such patients, you should always state you have no personal problems seeing anyone who needs you--you can't go wrong saying this! Many groups and hospitals are required, for example, to have a 'life-and-limb' list of doctors who rotate turns seeing uninsured emergency patients. If a hospital, for example, accepts any federal funds (Medicare or Medicaid), no patient can be refused in their Emergency Department. You are required to see such patients, as well as provide follow-up in your office, regardless of your practice preferences. That being said, if you're practicing geriatric medicine, everyone you see should have, at least, Medicare.
