The programme budgeting data provides estimates of primary care trusts' (PCT) expenditure on diabetes. However, the majority of expenditure relating to primary care appointments is included within Category 23a GMS/PMS so it is not possible to provide estimates of the cost to national health service of primary care related to diabetes. The programme budgeting data does provide a breakdown by care setting and does contain expenditure on primary care prescribing and is set out in the following table. This information was not available as part of the programme budgeting collection prior to 2010-11. Expenditure on diabetes in the inpatients, outpatients and other secondary care settings was £254 million in 2010-11 and £263 million in 2011-12. This information was not available as part of the programme budgeting collection prior to 2010-11. For in-patients, expenditure is allocated on the basis of primary diagnosis, so will not capture expenditure where diabetes has been recorded as a secondary diagnosis. For out-patients, expenditure is allocated on the basis of the treatment function code. This means that the diabetes figures will not capture expenditure relating to areas such as general medicine because this cannot be attributed to specific condition based programmes. The table provides a breakdown of diabetes expenditure by care setting for 2010-11 and 2011-12.

When it is not possible toreasonably estimate a programme budgeting category, expenditure isclassified as 'Other'. Expenditure on General Medical Services andPersonal Medical Services cannot be reasonably estimated at diseasespecific level, and is separately identified as a subcategory of'Other'expenditure. 3.The allocation of expenditure to programme budgeting subcategories isnot always straightforward, and subcategory level data should thereforebe used withcaution. 4.Estimates of expenditure are calculated using price paid for specificactivities and services purchased from healthcare providers. PCTsfollow standard guidance, procedures and mappings when calculatingprogramme budgetingdata. 5.The analysis of programme budgeting data by care setting was introducedfor the first time in 2010-11. For this reason, programme budgetingdata within individual care settings should be interpreted withcaution. 6.Due to differences in the level of information available to PCTs onA&E attendances a national split has been applied to PCT totalA&E expenditure to apportion it across programme budgetingcategories.
