The main data sources are two major collections of financial information from PCTs which have been brought together with information from other sources to provide these estimates of baseline spend.
The baseline estimates, which have been uplifted to 2012-13 values, provide emerging clinical commissioning groups (CCG) and local authorities with the information they need to support initial planning for the commissioning responsibilities they will take on in the future.
Understanding baseline spend is just the first step in establishing future budgets, and further analysis will build on this. As 2010-11 is the latest year for out-turn data, this provides the most accurate picture of current spend by PCTs.
Based on the analysis carried out on 2010-11 spend on public health, it is estimated that during 2012-13, the NHS will spend £5.2 billion on public health services, of which £2.2 billion will be on public health responsibilities, which will fall to local authorities in the future.
The information collected has also allowed an estimate of the size of spend on future CCG responsibilities to be developed, of around £64.7 billion.
