My experience with the NHS, especially A&E, has been nothing but exceptional. The care I've received after being admitted (wards, doctors, etc) can even be compared to private medical care in SA. They really do try their best with what they have available.
Not sure what an outsider's view of an NHS hospital is, but it's a million miles away from shitholes like JHB Gen, that's for sure. There aren't people dying in the waiting rooms with pangas still stuck in their heads, etc.
Wait times, in my experience, are unnecessarily ramped up by people who go to the A&E when their ailment DOESN'T REQUIRE IMMEDIATE EMERGENCY TREATMENT. I really can't stress that enough! I'm "fortunate" in that I usually get pushed to the front of the triage queue anyway, so usually only have to wait a few minutes when I go. But then again, I'm not there because I've stubbed my toe, or have a hangover (yes, that's an actual reason people go to the A&E).
