As you asked, examples of bad GPs (note the patients are close friends or close family members):
1. GP knows patient has migraines. GP prescribes type of contraceptive pill that should not be taken with migraine.
2. GP knows what medication patient is on. GP prescribes another type of medication that should not be taken with the first medication.
3. GP suggests anti depressants to patient, before even mentioning counselling.
4. GP knows patient has a medical condition. GP prescribes medication to patient that should not be taken with that condition.
5. And in my case, GPx2 says type 2 diabetes, I was 22 at the time! And not that overweight then. I finally see consultant. Consultant says of course not, don't be silly, far too young, tests for type 1, of course it is type 1.
Edit:
Actually some praise too:
1. I had a mole removed, under a local, the doctor could see I was worried/scared, when she had finished cutting it out she very quickly (and without saying what she was doing - trying not to embarrass me I think) hid anything with blood on or with a needle/blade so I wouldn't see them. I thought that was very thoughtful of her, she didn't need to do that. Very neat cut and stitches too.
2. I asked a GP about something, he said he didn't know much about it, and got a medical book out and looked up about it during the appointment, and told me what it said in the book. I really like honesty like that, you can't expect people to know about everything.
3. As I said before all specialists I have seen have been very good.
