Sadly thanks.
There really isn't any documentation besides Pro-QA itself, but I'm an EMD-Q with Priority and worked closely with an EMD-Instructor. The IAED does not give any recommendations on responses for the determinants, as these are all local policies. Our agency has 26-C-1 Sick-Altered Level of Consciousness as a BLS Code-3 response. After a year of researching data, less than 1% were ALS interventions required, so it was downgraded from a tiered ALS/BLS code-3 response to just a BLS ambo. But I can understand how that would be hard to implement in the game.
