I share your concerns with these types of errors, Sportster. Most of my doctors are with the same clinic, which just went to electronic records a few months ago. At first I was really excited because my old paper chart was about 4 inches thick and I was excited to be able to check test results online instead of waiting for the phone call.
The first couple of visits I had with doctors at the clinic, the nurse asked the usual questions about meds and medical history and typed the information into my file while I sat there. It wasn't until I left and was checking out the online system that I saw all the mistakes she made with my medical history.
Then one of my doctors had to phone in a prescription change for me. My last visit to the clinic I noticed that my medication list is showing that particular medication twice - one at the old dosage level and one at the new dosage level. So I thought...ok so if I end up unconcious and can't tell them which dose I'm actually taking, then what?
I'm going to talk to my doctor about getting it corrected my next appointment in a couple of weeks. To me it sort of defeats the purpose of having this great technology if you enter junk into it... junk in, junk out. Especially when you have multiple doctors sharing and using this data.
