There's one aspect about this that I haven't seen discussed, and it's one of my main concerns. I would like to start by saying that I blame all of Washington and both political parties for our current fiscal scenario, and I don't think it's going to be helpful to derail this into a political discussion, which it is not intended to be.
I'm worried that this would put us outside the rest of the field of medicine when it comes to reimbursement. I do understand the short-term pressures that led to the consideration of ROCR (hypofractionation, etc), but there are big-picture, longer-term issues which I don't think are properly being taken into consideration.
Mainly, while I'm less worried about the dollar losing its status as the worlds' reserve currency as I once was (BRICS has gone precisely nowhere, I think we're all, globally, seeing the benefit of having a global superpower with a powerful blue water navy, etc), even without that disaster scenario occurring the US will need to print an incredible amount of money to pay for the ~$140 trillion in unfunded obligations for which we are currently on the hook (Medicare and Social Security being the big two). The resulting inflation will require constant congressional/legislative fixes to the Medicare payment formula just to keep practices viable.
By disassociating from everyone else, we may be requiring an immense amount of work to be done by our advocacy organizations in the future, forcing them to continuously lobby to update whatever formula ROCR applies in an era of near-hyperinflation. Obviously, the details of the ROCR proposal will be important and will affect this risk. If, for example, the reimbursement formula is based on other areas in the house of medicine, then we could be somewhat protected.
Many in ASTRO's leadership likely will not be practicing at the time when these inflationary concerns will come to the fore. However, I'm fairly certain they will arise, as I cannot imagine a future where politicians dramatically cut services to their largest voting block- seniors. Only viable political option in our system is going to be to print the money needed to cover the bills. I really hope I'm wrong about the coming inflationary environment, but if I am not, I hope the proposal contains elements which help protect our future.
