Pre-cognition

Calvert et al. demonstrate clearly how care of diabetes has improved
annually in general practice, and rightly question the influence of QOF as
'not straightforward'.

The knee-bend in all trends in 2005 is readily visible in Figure 2.
QOF actually appears to be associated with a relative flattening-off.
This could be a ceiling-effect, a 'good-enough' effect, or a quirk of
retrospective data -editting ?

It reminds me of the early 1990's when vaccination target incentives
were introduced. That same levelling-off just above threshold (90%) was
visible in trends. What struck me as particularly noteworthy was not only
the knee-jerk DoH claims for the effects of performance-management, but
also the strong evidence for GP precognition..

How come GPs knew to aim their efforts perfectly toward that 90%
level, even before they knew the QOF rules ??!

Is it further proof of the power of retrospective prayer ??
