4.2.2 What was the average percentage
absolute adjustment made to crude Primary Care Trust populations
for (a) age structure (b) additional need (c) market forces and
(d) other in the 2007-08 weighted capitation formula? (Q50)
ANSWER
1. There are separate components in the
weighted capitation formula for the different services for which
PCTs receive funding: hospital and community health services (HCHS),
prescribing, primary medical services and HIV/AIDS. Each component
includes adjustments for age, additional need and market forces,
with the exception of the prescribing component which does not
have an adjustment for market forces.
2. Each adjustment generates a separate
PCT index, comparing the PCT score on the adjustment to the national
average. The indices are simultaneously applied to crude populations
to produce weighted populations which are then normalised, or
scaled, back to the national crude population. This produces PCT
weighted populations for each component which are combined into
PCT unified weighted populations using national expenditure weights.
It is not possible to produce overall adjustments for age, additional
need and market forces without giving a different weighted population.
3. The index for each adjustment is centred
on an average of 1, or 100% in percentage terms. PCTs with an
index greater than 1 for the age, additional need or market forces
adjustments will be above the national average and those PCTs
with an index less than 1 will be below the national average.
4. Table 50a and Figure 50a show
measures of dispersion and the average percentage absolute adjustment
for each index in the HCHS Component in 2007-08. Table 50b
and Table 50c show the range for each index in the
prescribing and primary medical services components in 2007-08.
5. There are two other adjustments in the
2006-07 and 2007-08 weighted capitation formula: the English language
difficulties adjustment (ELDA) and the growth area adjustment.
These are adjustments to monetary targets rather than adjustments
to crude populations.

4.2.3 What percentage adjustments were made to crude
populations for (a) age structure (b) additional need (c) market
forces and (d) other for each Primary Care Trust in the 2007-08
weighted capitation formula? (Q51)
ANSWER
Table 51 shows the age, additional need and market
forces adjustments expressed as indices centred around 1 for each
PCT in the HCHS, prescribing and primary medical services components
of the weighted capitation formula in 2007-08. It is not possible
to produce overall adjustments for age, additional need and market
forces without giving a different weighted population.
