No, defensive medicine is not dangerous. It's expensive. There's a difference.
The ambulance does not own you if you're tanked, and you'll never see paramedics walking into a bar putting people into handcuffs because they've got nothing better to do.
The issue on the table is what to do when EMS is called to the scene of a patient who has been drinking and has an altered level of consciousness.
Like it or not, in the United States (which last time I checked cares more about individual liberty than just about any other country in the history of the world), if you're an adult or an emancipated minor who can't make an informed decision about your health care, an agent of the state (edit: or your health care provider) is expected to act in your best interest (with caveats).
Dismissing a head injured patient as a drunk is clearly not acting in the patient's best interest. I'm sure we're agreed on that point, at least.
P.S. You have PD nurses and doctors? Do they come to the scene? Also, do you have access to the guidelines that determine whether or not a person who has been drinking can be in a cell? I'd like to see it, just for curiosity's sake.
Can the person account for themselves, their recent history and sufficiently care for themselves? If not, go to hospital.
Just becasue you are tanked,doesn't mean the ambulance owns you.
Here our PD has a guideline that determines whether or not a person in custody is safe to have ina cell. this includes review by a PD nurse or doctor. If unsafe-->ambulance.
Really, legalities like this has ruined health care. Paranoia medicine is just a dangerous as neglect.
