@Sandybval I think it used to be centralised but it went regional because it was err inefficient.
That's the understatement of the year.
It meant there was no way for anything to be sourced from anywhere other than the scentral source. So eg the Hospital I worked for was part of HA that had an old Victorian asylum which had things like a printing service run by patients with learning disabilities, the hospital had utilised that and printed patient letters for free. Then the department suddenly had to get the letters from source.
Then the batteries. There is a thing called a holter monitor, it records your ECG for 24 hours, non stop.
We got our shipment of batteries, the first set didn't work, the second didn't (you occasionally got the odd batteries that didn't work) at that point the patient was asked to go get a coffee while we phoned the holter manufacturer.
It turned out the reason they recommended one brand of batteries was because the other manufacturer put a coating on the contacts.
So you had highly skilled staff scrubbing the contacts of batteries for 10 mins.
Then when it came to large pieces of equipment, think ultrasound or X-ray. Three hospitals would put in three requests to companies A, B and C, there are reasons each department wants a different machine, instead the 'central procurement' would go to company D and negotiate a reduced price to buy three machines, non of which were ideal and some of which meant other equipment wasn't compatible.
Sorry - rant over.
When I rule the world all NHS management will spend 1 week a year doing a range of shifts in different departments.
