Quite possibly. My 'evidence' for the existence of inept NHS procurement outcomes emanates from my sister-in-law (NHS senior nurse) and wife (NHS Temporary Staffing Coordinator). Not to mention how often they bang on about the wasting of money that exists for internal practices too. But, yes, I accept any 'evidence' I have is largely 2nd hand and anecdotal.
p.s. the temporary staffing issues (e.g. extortionate agency rates) at the hospitals that my wife covers has pretty much been sorted now, resulting in significant savings.
