You might enquire to the NREMT research department, they might be able to assist you. I too also doubt that it would be beneficial in aiding in wages. I ask why one consider raises would decrease suicide rates? It would be hard to correlate suicide to the pay structure and it being the cause. There are several "poor" people that do not commit suicide, therefore eliminating the point.
As well, this does bring up an issue that possibly a psychological evaluation maybe should explored for those entering the profession. Possibly in lieu of pay raises, psychological check ups and examinations should be performed. Just like those that perform under stress environment.
If one is attempting to adjust raises, I suggest to stick to the facts that you provide an essential service. That you are part of the medical community and should have the benefits and wages as accordingly. I would using the "what if" scenario, if something should happen to their families or themselves; whom and how much should those indivuiduals recieve?
