STRUCTURE: King’s College Hospital, Guy’s and St Thomas’ and South London and Maudlsey Mental Health foundation trusts are considering a full merger, it has been revealed.

The three trusts, which have a combined turnover of nearly £2bn, have revealed that a full merger is an option they are considering.

King’s Health Partners, the academic health science centre that comprises all three trusts and King’s College, University of London, has commissioned a further “feasibility study” which will make its recommendations in January.

The review by William McKee comes shortly after HSJ revealed University College London Partners was expanding to include Barts and the London Trust and the founding of Imperial Health Partners was announced.

The proposed merger would be the first between in the country between mental health and acute trusts.

South London and Maudsley’s 2010-11 turnover was £360m, King’s £583m and Guy’s and St Thomas’ £967m.

A combined trust would be the largest in England, dwarfing even the proposed Barts, Whipps Cross and Newham hospitals merger which would have a combined turnover of £1.1bn.
