Insight from someone whos clients are too familiar with hospitals and have specific needs and low incidence conditions is that the process is so standardized and uninclined to change. Ambulances and other hospital staff refusing to listen to a patients mom instead of following their protocall gave one person with disabilities a dangerous level of hyponatremia.
They're on a medication that makes them hold water so we've been instructed to tell people he needs whats called half normal saline for his IVs or he'll be overhydrated and his blood salt levels plummet. Its a 50/50 if the responder listens to us or just does their normal protocal. In emergency situations his parents no longer call rescue or take him to the hospital until they have one of his doctors on the phone, because then people listen instead of almost kill him.
