There is one mention of NHS Scotland in the above but, of course, no comparison.

From BBC Health today:

Spending in this area rose by 20% last year to hit £3bn in England.

From STV in August 2022:

Expenditure on locum agency nursing staff amounted to £92,295,816 in 2021-22.

Regulars know where I’m going. England has 10 times the population so, all things being equal, should have been spending around £920 million. NHS England spent £3 billion, more than three times as much pro rata.

As for the agency charging £2 500 a shift:

While the majority of health boards did not say the highest amount they had paid for someone to do a single shift, NHS Ayrshire and Arran revealed it had spent £1,710.98 on one nursing shift, while NHS Lothian has paid up to £1,903.09 per shift.
