Just one of many, many stories on this:
Literally yes. Keeping them in an ambulance instead of the sidewalk won't get them into the ER any faster. And keeping the ambulance tied up at the hospital won't do any good for the next guy who has an emergency and is sitting on the sidewalk at the site of the accident either. At least if you move the injured people to the sidewalk at the hospital, the nurses can look outside and prioritize the worst. And the problem will be highly visible to the public, instead of papered over by using ambulances as waiting rooms.
What they're doing now is obviously prioritizing for appearances, not patient outcome.
Even if the hospital's ER room has saturated capacity, moving all the casualties to the hospital waiting room as rapidly as possible still has utility because that allows the hospital to prioritize the worst, which they can't do if the worst is laying on the street a mile away with the ambulances all parked at the hospital.
If someone is walking-wounded, they WILL be unloaded to sit and wait for 6 hours in a corridor.
The people who the ambulances are holding for long periods are those who are too sick to be left without attention. The paramedic staff continue to monitor them in order to escalate further if their condition deteriorates, and depending on the situation, medical staff from the hospital will be involved in this.
The ambulance staff obviously have a moral and legal duty of care, and can't just leave a seriously unwell patient on the floor outside the hospital entrance to get to the next call, which would likely be a patient no more ill than the one they just abandoned.
Oh we just double the number of nurses? Yeah, but no. They don't grow on trees. The current ones don't stretch (we asked). You can't just absorb 20-40 patients into your acute departments without space and staff. The paramedics are acting as those staff, their ambulances the space. Yes it's far from optimal.
It's all about throughput. You're only looking at the front while the problem is in the back.
Until they go, A&E can't admit people through to the beds they're currently in.
Even if you lie to the population and claim you'll add 7000 beds this winter, those beds aren't staffed. We can't surge 5000 nurses and 2000 support staff out of nowhere. They're all busy.
This is such a stellar use of the handwavey "just" that I feel we should have it bronzed.
