I'm afraid you misunderstood, sir. I have a clinical practice. I am still practising clinically. Some of the patients in our clinic are patients of mine. I do not refer out. I am busy enough on a day-to-day basis in my day job, which turns into a night job and a weekend job as well. I don't have time to practise outside.
Yes, there are ethical guidelines. There are regulations in place, both from our medical governing bodies and within the military, to govern situations such as that. We won't normally take a patient who is being seen by a clinician in our clinic and refer that patient to their private clinic downtown unless there is a legitimate reason for it. All referrals are reviewed, and anything like that would be very closely reviewed.
