I've heard it before, and I'll say it again, if it's a true emergency, the patient doesn't need a paramedic, they need a doctor. What if this is a significant trauma, a dissecting aneurysm, etc? What if it's a STEMI? Every second is cardiocytes. Does it matter if there is a paramedic on scene or not already? The patient needs to be transported as soon as possible.
I am sure right now, American Medical Response (AMR) time won't change significantly, but over time, I am willing to bet that they will be willing to put less units in service and hire less ambulance personnel because they don't need that many units to meet their contracted response time.
At the same time, I agree with JPINFV. I hate hearing about how Fire regularly beats transport to the scene, and they boast about being able to respond quicker. In my area, they are usually more expensive because of higher pay, more staff, more expensive equipment/vehicle (e.g. fire apparatus), and *usually don't do more than put the patient on oxygen, get the patient's first and last name, date of birth, age, and their chief complaint. I believe we should put less money into Fire and more into EMS. This will be just one more reason why they'll try to convince the public and legislature that they needed, and why more should be invested into them.
*Based on my empirical experience, which is limited in the 911 system, and conversations with Fire/Paramedics that teach at the schools that I attended or are currently attending.
