It's essentially the "Rocky IV" argument of residency training. Who got the better training, the Russian with the high-tech equipment and everything handed to him, meaning all he had to focus on was getting stronger? Or Rocky, who had to build and maintain his entire training system out in the snowy wilderness? Pushing aside the "American exceptionalism" the movie is trying to push, I don't think there's a clear answer.
I totally agree that needing hands-on experience with indirect patient care tasks is very important. However, in an ideal world, the only places approved to have RadOnc residency programs should have the infrastructure in place where this is not generally "necessary" for the majority of tasks. My program accidentally strikes a weird "balance" (and I use that term cautiously) where most services have most admin tasks handled most of the time. Then, there are services which have weird components to them which the residents are required to handle. There is a piece of me that believes "learning" these tasks is valuable, but how many times do I need to schedule an MRI appointment before I figure out how to do it?
A long time ago, far far away, I was a secretary myself, so perhaps I resent getting told I'm "learning" a job I did when I was 19.
