1. The head of the department is the best person to do the procedure.
    The head of the department has to devote a significant amount of time to administrative work. That means less time in the OR. You want the doctor that is doing the procedure multiple times a week.
  2. A good Yelp score = good medicine.
    I hate Yelp for doctors. Some of the best doctors I've worked with have had horrible, unwarranted things said about them. Some doctors who have "great" Yelp scores do not practice good medicine, but give in to patient demands and know how to schmooze.
  3. A teaching hospital is bad.
    Teaching hospitals tend to be the most up to date on the newest guidelines and medical research findings since they are teaching residents and medical students. Plus, you have not one but a TEAM of doctors reviewing your chart and examining you!
  4. The older the doctor, the better.
    Medicine is one of those fields where looking older is desirable. My last boss told me he had the advantage of gray hair and wrinkles after a patient I saw for an ovarian cyst asked for a second opinion. Yes, older docs have seen more and have more experience. That being said, sometimes older docs are not as comfortable using the newest surgical technology. Just keep that in mind. I think the sweet spot is 8-10 years of experience.
  5. It's OK to be late for appointments because the doctor is usually late.
    Yes, doctors sometimes run late. But it's not because we're golfing or having a leisurely lunch. It's because the patient before you came late, a patient needed emergent medical attention, a patient call took longer than expected, a patient with a disability needed extra time, etc. A masseuse can tell you that you only booked a 30 min visit so if you showed up 10 min late, you're only getting a 20 min massage. Doctors care about the patient in front of them. Coming late just compounds things.
  6. It's OK to book a 15 min appt for a 30 min problem.
    Doctors are happy to address your issues. But please, please, please book an appointment appropriately. I can't tell you how many times I've seen a patient for a minor issue like a UTI only to be stopped as my hand is on the door knob because they want to talk about infertility or decreased libido. I hate not fully addressing patient needs, but I also hate making the next few patients wait when they showed up on time. Be understanding if you're told you need to come back for another appointment.
  7. Doctors make loads of cash and/or do procedures to make money
    It really depends on the institutional structure and the specialty, but especially for primary care doctors, medicine is no longer a particularly lucrative field. We're not trying to profit off of patients' pain.
