Wow this is all very helpful.
I have not been keeping track of the pharmacies that claim not to have received the prescriptions. I will keep a list and see if there's a pattern. Thanks, Jimmie.
And Jimmie, I too am suspicious about what actually goes on in the pharmacy. I used to fax prescriptions. Despite my fax machine insisting that the fax went through, at least 75%--mysteriously--were claimed by the pharmacy not to have appeared when my patient got there. They explicitly told my patients that I had not done what I said I would do, making me look careless or bad. So I embraced eRx because of its auditable trail. This worked great for a while, but I have gradually experienced pharmacists now claiming that I never sent these, despite the confirmation. I believe that it's just a lie, to shift blame from them to me, and to help them manage their workflow, even if they screw up mine.
