I think Jeremy Hunt beat you to it
I heard a doctor on LBC discussing this issue, her thoughts were that yes, there a level of public visiting A&E for non emergency reasons which exacerbates the situation but it is a contributry factor, not the primary cause.
The primary cause is multi factoral, but one key problem is that social services cant and wont move patients out of hospital blocking the sytem all the way back.
On point she did make was that on average every Monday she typically sees 4 people that have a bad sore throat but no temperature, which does not need a doctors visit to identify. These patients should be, taking advise from relatives, visiting a pharmacy, looking up on the NHS website or ringing 111. Her opinion was that todays culture is not medically savvy and dont take responsibility for their own health where minor ailnents are concerned.
I think I agree, having had staff off sick with bad backs, my advise is go and visit a private physio, sports injury clinic, osteopathe. Usually though Its always, Ill get a doctors appointment first, which is a total waste of time. My wife, I have to say had the same opinion, after 3 days of being barely able to walk I finally managed to persuade her to visit a physio clinic, half hour appointment and able to walk easily again (and exercises with an exercise ball which are fantastic for lower back pain).
I have heard that disorganised people that run out of prescription medication do visit A&E and its a common occurrance
