This happened before all that
My gut reaction is that for the most part you'd be wrong, which sent me scampering off to Google and I came across a few moderately interesting things. Much to my surprise (as I thought MRSA was a recent thing) it was first discovered in 1961, and yes folks, appears to be another British contribution to the globe.
In 1993, 51 people appeared to die from it in UK hospitals. In 2005 this figure rose to 1652. The reforms that heralded in the Primary Care Trusts and Hospital Trusts were introduced earlier, under the National Health Service and Community Care Act 1990, also commonly called the "internal market". It was these Thatcher/ Major reforms that introduced the new procurement and management cultures, which in fairness Tony Blair would do little to reverse until 2005 when he's halved the number of PCT's. The legislation was enacted slightly after 1990, due to timescales, and took a year or two to bed down on the ground. I won't dwell on that other than to say look at the figure for MRSA deaths in 1993 as it is about at this time that the Hospital Trusts started to swing into action, and where they were 12 years later. Coincidence? It would be possible to have died from MRSA prior to 1993 of course, but there can be little doubt that a vast majority of deaths came under the new arrangements.
The bastion of private sector health care is of course the great US of A. If I think our quasi private sector trust arrangements are a stain on a civilised society that we should be ashamed of, than their figures leave me wondering if they haven't put their various private sector bankers and hedge fund managers at the helm of their health care provision!!!
1999 - total number of deaths = 127,000
2005 - total number of deaths = 278,000
My God they go to war for about 1% of that total bodycount!!! It strikes me they'd be better off turning their guns on their own private sector health providers, who clearly represent a statistically greater threat to their well-being, than any terrorist group.
The final piece in the NHS Trust thing seems to relate to the award of PFI cleaning contracts, as there is certainly no shortage of anecdotal evidence that squeezing profits through cutting corners has been a contributary factor. I can't find any precise evidence as to when the first service contracts were introduced but first remember coming across them in about circa 1995/ 96 when Ken Clarke was Chancellor. With that in mind, I suspect they came into play before this, as I wouldn't expect to be at the leading edge of such developments, so I'm inclined to think they emerged at the same time as the internal market and cost centre management was being introduced from 1993 onwards? Again, the introduction of PFI seems to mirror MRSA, (though clearly the Americans have taken that to a whole new level, and decided to wipe out a population the approximate size of Newcastle upon Tyne)
