We also need to be careful about what is meant by a nurse in post - seems pretty obvious but it isn’t.
Having been in public service for a long time I have seen this over and over, numbers rarely mean what they purport to say, and this is because of the management measurement system that is used to cover up reality whilst appearing to achieve the desired outcomes.
Anyone in public services will be familiar with the process of inspection and targets - these are rarely intended to assist the organisation in identifying areas for improvement. These usually come in the form of Key Performance Targets(KPT) or Key Performance Indicators(KPI)
Ostensibly an the organisation will be issued with a list of measurement standards - usually a set of statements at varying levels or standards and the organization is then expected to operate in a way to achieve the highest standards given the resources they have. The inspectors will then visit and require evidence to be provided that shows what has been achieved in relation to those statements.
So if the NHS has been given an intended measurement of numbers of nurses, the devil is in the details - what is actually meant by a nurse? Is that a student in last year of training? Is that a person who is actually a ward manager and rarely interacts with patients, does that mean nurses who are NHS registered but work in private care homes? Does that mean a nurse in post who works 37 hours or just any registered nurse who works part time.
The hospital managers and directors have careers that are dependent upon achieving the inspection results - this does not necessarily means provide a good service - the two are not the same thing at all.
The result is the there is huge incentive for the whole ministry and management chain to change indicators to fit a definition - so suddenly a nurse becomes who they say it is, I’ve seen so many dodgy ways of meeting targets - such as defining a multi-disciplinary case as several cases at once, when in truth it refers to one person with multiple issues - which means that fewer bodies are being counted more than once.
In the case of a nurse, well for maybe 20 hours they could be working say, on infection control and perhaps another 5 hours doing paperwork and managing staff working hours and maybe work one shift a week with patients - would you call that a full time nurse?
This is the sort of abuse of targets and inspection processes that happen throughout the whole of the public sector - inspections cost an absolute fortune but in the end they largely reinforce the culture of deception because it is on no-ones interest to blame poor performance on lack of resources - that would be very bad for a career.
All this in turn enables a minister to get up on its hind legs in parliament or on tv interview and bray on about how certain performance numbers are showing an improvement, when it is all lies.
Both Labour and Conservatives have relied upon these lies for the last 20 years, neither has a real interest in exposing the truth on their watch since it makes them look bad.
