It’s an anecdote about a government incentive to have doctors see patients within 48 hours causing doctors to refuse scheduling patients later than 48 hours in order to get the incentive bonus.
This is not an example of limits of data, but an example of perverse incentives.
That part is probably just the first 1/8th or so of the article (rough guess). Sounds like it was cut short for you?
This case could be said to be creating misleading data. If the doctor's offices aren't recording appointments more than 48 hours in advance, the System is losing visibility on the total number of people who want appointments. Every office will appear to be 100% efficient even though there is effectively still an invisible waiting list.
I just tried opening it in Firefox now (a couple hours later) and I see the whole article. If I switch to reader mode I do see it's truncated about halfway through, but I think that's a separate issue from what the OP was seeing.
But also without reader mode I can’t see more than the NHS anecdote.
