I would bring up the issue at my next appointment, and make sure to do as much research as I could. Depending on how far along you are it can be a real nightmare finding a new doctor that you like. But ultimately if you truly don't feel comfortable with him then switch. You are the only person that really knows what's happening in your body during labor, and you need someone that will listen to you.
If it is one complaint then I would not be to worried. I have a perfect Dr and an entire midwife team at the office I go to. If something went wrong with my or any other woman's pregnancy at the office we could complain weather it was the Dr or midwives fault. An angry mother that loses a child will try to blame anyone even if it was unfair to do so. If you are very concerned try to find out exactly what happened with the case. You can find out from public record about how many accusations that a Dr had and what ever came of the situation.
If it would make you feel more comfortable you can find a new Dr. If it was me I would ask my Dr about the article and that I had some concerns about what really happened and the safety of my baby. But I try to build a good relationship with my Dr early on and be open. He can tell you of ant accusations against himself and outcome as long as he don't give basic patient info or identity the patient. Good luck.
Every doctor has their perks and down falls. You'll never find a perfect one. But if your not comfortable I'd switch.
I think you need to feel safe and comfortable with your doctor. So if you don't and it's still early enough then look for another doctor. If you're far along in your pregnancy you might not find another doctor who will take you on, but you can ask for a second opinion. And check around for more information on the doctor you currently have. It's hard to get all the facts from one article. You may find out that he wasn't negligent, just investigated. Ultimately though I think you have to go with your instincts. With any doctor you have to pay attention to your body and what you think is right and fight for that.
I would suggest looking for another doc if you seem that article about you doc. I would just feel safer with a new doc. Wouldn't want anything to go wrong that's just MY opinion but it's your decision good luck momma
