I could be totally wrong but to me looks like quite a few drug addicts and possibly homeless in and around the waiting room waiting to be seen. Towards the end of my brief stay heard a patient inside screaming for 15+ minutes.
Emergency Depts are like a Zoo, the closest facsimile I can come up with is the LAX TBIT check in in the evening and no F/J check in. A Sea of humanity. What you described is actually par for the course. I get what you are saying - you thought you were being discounted. Unfortunately that often happens - the Triage see all sorts of people coming through, you were just another "walking wounded". How long were you waiting for?
There are set criteria for this. There is "struggling to breathe" and then there are clinical signs of breathing trouble which point to potential trouble.
Similarly there is "bleeding to death - I cut my finger and there was blood everywhere" and actual bleeding to death.
Triage has heard it all before.
But again, Triage can get it wrong from time to time, so the saying "a squeaky wheel gets the most grease' often applies.
A mother who keeps coming up to triage and says there is something wrong with my child is a Red flag - not that the mother is nuts but a Red Flag for a reassessment. Its not a perfect system but overall an excellent system.
Its not only what you say, but what you say accompanied by physical signs.
Where A&E falls down is basically due to a lack of hospital beds (can't move patients along) and unavailability of GP services especially out of hours and often affordability - bulkbilling etc for the Cat 5 Walking wounded. Don't get me started on the Govt/Medicare not properly funding Primary and Chronic health care in the community.
Private A&E fees (apart from the Drs, pathology, and other tests) are not rebatable through medicare so the SNT is not applicable. Not sure how you got it for free.
