Before you say zero, consider these common falsifications:
1. Stating you checked equipment on a checklist that you didnt check.
2. Documenting more sets of vital signs than you actually took.
3. Changing the "times" for treatments during a cardiac arrest so that they match the protocol.
4. Documenting a "patient refusal" when you really talked them out of going to the hospital by EMS.
5. Documenting a treatment that you did not do (a glucose reading).
6. Falsifying your actual enroute time during sleep hours.
7. Documenting there was no patient when there was one at the scene.
8. Falsified an incident report to protect yourself or a partner (yes we had a backer on the ground).
I'm gonna have to say zero. Our department has fired SEVERAL people for falsification of records and written up several people for it depending on the infraction. IE, falsifying a vehicle check off would get your reprimanded, falsifying a PCR will get you fired. PERIOD. We don't screw around with PCR's. If you didn't do it, you don't document it. If you did do it, you better document it.
Some of your lists might need some clarification though. 3. for example. There's some discrepancy with 'times' between the time shown on the monitor, the 'time' that dispatch has and the 'time' on everyone's watch in the rig. The 'time' difference between dispatch and what's actually on the monitor is about 3 minutes. So who's time do you go by when you document what and WHEN you did it? That's not falsification though. As I've said before (and not everyone agrees with me), protocols are a GUIDE, they aren't set in stone. So if protocol says you must be transporting within 10 minutes, there's room for wiggle because it took 15 minutes to get the patient out of the BASEMENT, up the narrow steps onto the cot and out into the ambulance.
I think sometimes 4. needs to be adjusted too. If we're called to a 30 year old with a low grade fever and ten family members standing around doing nothing and the only reason why they called is because they think that either a. we can give them a magic pill to make them better and / or b. they'll get in to see the doctor faster because they come in on the ambulance, we have no problems telling them that neither of them are true, take yourself to the hospital. Just because we 'talked them out of it' doesn't mean it isn't a patient refusal. So that's not falsification as long as your saying all the things you're supposed to say.
And how, exactly, do you falsify your enroute times during sleep hours? You get a call and your asleep and you grab your radio and announce 'enroute' as you roll out of bed getting dressed. That's enroute as far as I'm concerned. If you're on your way to the ambulance then you're enroute. Does it matter that you have to stop at the bathroom on the way? That's not falsification. Now, in the same vein, if suddenly your time between 'enroute' and 'on scene' suddenly start getting longer, someone might wanna pull you aside and say, 'maybe hold off on saying 'enroute' until you actually start the rig and pull out of the bay.'
I guess my point is it's all up to interpretation and who's doing the interpreting. I'm still going with zero.
