The Five Year Forward View, which was published in 2014, set out how the health service needs to change by designing several new models of care which break down the barriers between general practice, hospitals, community services, and social care.
Two of the models outlined were MCPs (multispecialty community providers) and PACS (primary and acute care systems). These are population based models of care, built upon the GP registered lists of the practices involved covering a population of circa 50,000 to 100,000.
However, it is expected they will vary in size dependent upon local agreement. MCPs seek to integrate primary and community services, but can also include moving some hospital services into the community, or employing hospital doctors to work in the community.
PACS will include NHS list-based GP and hospital services, together with mental health, community care services, and potentially public health or social care. As such, NHS England would expect PACS to cover the same population footprint as the Trust(s) involved.
