I agree that lying to a patient (in most circumstances) is not the professional method to 'get someone to the emergency room'. We had a thread here recently that discussed points similar to this one and I cannot find it. Anyways, I will repeat what I said in that thread. For starters, I will post the definition of coercion.
co⋅erce [koh-urs]
–verb (used with object), -erced, -erc⋅ing.
1. to compel by force, intimidation, or authority, esp. without regard for individual desire or volition: They coerced him into signing the document.
2. to bring about through the use of force or other forms of compulsion; exact: to coerce obedience.
3. to dominate or control, esp. by exploiting fear, anxiety, etc.: The state is based on successfully coercing the individual.
Pay special attention to number 3. Exploiting fear, anxiety, etc, to dominate or control. In essence, getting the patient to do what we think is best for them. Another way to say it, and this one of my favorites which was stolen from DwayneEMTP, 'gifting them with our advocacy'.
We, as professionals, have an obligation to respecting the freedom of choice concerning our patient's bodies (if they are capable of making decisions for themselves). We, as professionals, have no right or obligation to scare patients into going to the hospital because we know or think it is best for them. The decision is and should be their decision to make. Telling patients things such as 'you will die if you do not come with us', especially being a small remote chance, is coercion at its finest. Informing patients about complications of their medical condition is one thing, using those complications to promote your agenda is something entirely different.
The same holds true for those who threaten medical procedures. 'Wake up or I will put a big needle in your arm' or 'tell me what pills you took or I will have to shove a tube through your nose to your stomach' or 'you will die if you do not hold still' etc are all forms of coercion. We should honestly take a look at how we talk to patients. Sure, compliance may be easier if you use coercion. Taking a moment to talk to your patient, explain to them the why behind why something is warranted go a whole lot further with patient interactions than using some of the above phrases.
