I to have recently proposed a research paper on the abuse of the 911 system. People will call 911 for anything, and we all know about these so called "frequent fliers". We get a call to John Doe's house again and while I'm there, all our other ambulances are covered on non-emergency transports, we have another "real" 911 call that doesn't involve John Doe's headache today. There is nothing more frustrating than getting out of the bed at 4 in the morning for a bull crap call that ties up someone's "real life emergency". My research paper showed that not only was response time slowed by the emergence of nuisance calls such as this but it also gave providers a mindset that every call that they receive at that address will be a bull crap call. So hence we have another story of crying wolf. Similarly I did notice in my research that people would respond slower to calls that are dispatched similarly to bull crap calls. IE almost %80 of the calls that were "illness" in nature were ran as a bull crap call. In other words, the provider may get a soda, use the bathroom, or other things to take there time instead of running the call code 3 until told otherwise. Maybe you could focus your research on these topics because there are no real findings of researchers who have researched the topic of abuse of the 911 system except for myself that I could find.
