The health secretary has ruled there is insufficient evidence of the benefits of formally merging Chase Farm Hospital with North Middlesex University Hospital, HSJ understands.

Andrew Lansley has accepted the findings of an NHS London feasibility study which said although the clinical integration between the two hospitals should continue there should be no merger.

An official announcement has now been made

The Barnet, Enfield and Haringey clinical strategy will see approximately £50m of services transfer from Chase Farm to North Middlesex University Hospital, including maternity and A&E services.

Mr Lansley approved this scheme in September.

The merger proposal saw objections from Barnet Council and medics at Chase Farm, HSJ understands.

The transfer of services will see the £175m-turnover North Middlesex clear the £200m-turnover mark, considered by some as the minimum size for a viable acute trust.
