To me, this smacks of the MRSA problem the NHS (UK) had.
MRSA is an antibiotic resistant bacterial skin infection people can get and people were getting them in UK hospital. It does happen in hospitals but the rates of infection were too consistently high at the time because they weren't catching outbreaks soon enough and when they did, they didnt act soon enough.
After the public and news groups became aware of the problem, reforms were promised. An investigation showed that new, improved reporting measures should fix the problem. When they implemented the policies from the investigation and improved their reporting practices, you'll never guess what, reported cases of MRSA went up!
What a surprise.
If you had continued the trend lines from that, then I'm sure you can guess the kind of inflated "top end" figures you'd end up at.
I mean, there might turn out to be a problem but you also have to account for improvements in reporting standards.
The real problem is, improvements in reporting standards and improvements in interdepartmental coordination is boring as fuck! Who wants to read about that?
