Now we’ve identified and measured their needs for health care - how do we convert to resources??

not equal is equitable
Ah, but...
Jim lives next door to a hospital and even though a complex fracture - discharged home. Actual cost = £2,500.
Jessie lives on an island and is admitted prior to her due date to ‘wait for labour’. Actual cost = £2,500.
Hence if we allocated them equal amounts under these circumstances it would be equitable.
Ah, but...
Jim = £3,500
Jessie = £1,500
Ah, but...
Average cost in Scotland to treat asthma = £1,000 per annum…
Give Jessie an extra £1,000…Jim = £2,500Jessie = £3,500
Living within our means...
Both now have unmet needs, but its equitable!

Ah but...
We’re allocating resources for next year… will Jim break his leg?... will Jessie have asthma?... will Jessie get pregnant?
Need to predict probability of events.

Ah but...
Remoteness adjustment
Jim - share before remoteness = 20.2% 28.6% (extent to which costs are lower) x 20.2% = 5.78 20.2 - 5.78 = 14.4%
Jessie - share before remoteness = 79.8% 67% (extent to which costs are higher) x 79.8% = 53.466 79.8 + 53.466 = 133.3%
Jessie = 133.3/147.7 (133.3+14.4) = 90.3% Jim = 14.4/147.7 = 9.7%EQUITABLE!
Every health board has Jims and Jessies...

Themes
Equal is not necessarily equitable We need to identify (broken legs, asthma, pregnancy); measure
(what is the probability of those health events) and value (probability x cost of health events) the need for health care.
We need to be able to predict health events for given populations.
Some differences we take account of and others we don’t. We don’t allocate to providers - prospective payment. Unmet needs exist and this matters for a needs (cf. use) based
formula. We’re not calculating the size of the budget, but how to share it
out.
