The nurse who attended to me took my BP manually after using machine. The machines you have in all Prisma facilities are always high and inaccurate.

Able to see my doctor, PA or NP in a timely manner. I had to go to an urgent care center the first time to be treated for my respiratory condition. I have asthma and not getting a respiratory infection dealt with quickly is a real problem for me. Very disappointed that wasn't made to happen.

I would suggest that every time I use a Prisma doctor or facility, you don't survey me afterwards. I've seen quite a few doctors and facilities and it's rather stressful, but I'm very happy with all my Prisma doctors.

The staff is great but Prisma has the doctors so tightly scheduled that it interferes with the opportunity for patients to bring up new concerns. The doctors don't have time to ask "what else is on your mind or concerning you about your health" because Prisma has them on a schedule that rushes them off to the next appointment. As a patient I need to be bold and strong enough to bring up a new concern on my own if I find the doctor is ready to wrap up and move on when I still have something on my mind.

Not sure if 15 minutes, is adequate time for a yearly visit, or just time allocated for Medicare patients?
