There's a large and inconceivable disconnect between a field that focuses on data minutiae, and even takes pride in it, but then has a collective melt down to analyzing the data about jobs and future employment.
SDN didn't publish the projection that we are training more residents than needed. It can be argued that projections are not facts. This is true. However that same methodology was the bedrock of expansion, as blessed by ACGME, SCAROP, ASTRO, and all other organizations who want to take responsibility sometimes, but only when it suits them. None were excising caution about expansion of 50% of slots when based on only a projection.
Similarly, SDN did not expand fellowships from the teens to mid 20s-30s in a few years. At least I don't think we did. It is a curious piece of data that programs were able to open more fellowships, which do not provide any new or unique skills, if the job market was so robust.
Did SDN have 50% of the practicing workforce fill out their surveys to say 'oversupply' was the main concern of the field? I wonder.
There are hard and soft data points. Employment is difficult to get a good handle on. There was one PRO report that for 1 year the job posting matched the number of new residents as the only data point in the affirmative. Hypofraction is less treatment - can be a wonderful thing for patients, should be encouraged, but someone has to explain this math to me how it magically equals more patients. The only firm data point about hypofractionation is that we are treating less.
SDN is great for bringing perspectives otherwise not allowed to be said. The rise of the satellite job - private practice work for academic pay and bureaucracy for instance - which otherwise has no way of filtering to medical students and is a very real and poor change for the field (poor in the sense is it limits advancement and opportunities compared to the generation who came before, whether it was there overt intent or not).
This forum and it's discussions are worth defending, and even with the emotion and derision no one on the ASTRO forums or twitter have taken any significant stab at addressing the above points.
