From what I saw, the assembled physicians acquired their own supplies, spread out across the affected zone, made themselves known on the network, and even made house calls at significant personal risk in the midst of a zombie uprising.
Now, some people reached out and offered aid in couriering supplies and injured, making food to support medical staff, reached out to ask what they needed. And that was all very helpful. There were scattered attempts at supportive pharmacological research that could have been promising in time. But some bureaucrat attempting to micromanage medical staff isn't helpful.
You complain we were spread out. The population was spread out. Centralizing doctors creates a target that could wipe out all medically trained staff at once and would hardly have helped unless all of you were centralized. And even then would have been an asinine choice that neglected the very real concerns of quarantining the injured so one patient didn't suddenly become a zombie and kill all recuperating patients and the attending medical staff.
So by the ruby rings of Ragadorr, criticize to the aether all you like. But don't expect to hear back from it. We put our lives on the line doing what we needed, what we were trained for, and what we could.
Perhaps you instead you instead need to work on reporting injuries in a more efficient manner or some transport service.
