The accountable officer of a clinical commissioning group under NHS England legal directions is to step aside to take a new role in the local “accountable care partnership”.

Katie Armstrong, chief clinical officer for Coastal West Sussex CCG, will become clinical lead for a planned accountable care partnership, Coastal Care.

Her place will be taken in the short term by Ralph McCormack, who had been the CCG’s executive lead for stabilisaton and transition, while the post is advertised.

The moves are likely to lead to other changes in the troubled CCG’s governing body, as CCGs are required to have a clinician as either chair or accountable officer, and Dr Armstrong’s departure means this is no longer the case for Coastal West Sussex.

Existing lay chair Kieran Stigant is to remain until March 2018 while a new chair is appointed.

The moves – which have been approved by NHS England - come after the need for senior leadership team development was identified in a capability and capacity review commissioned when the CCG went into legal directions.

The CCG is also proposing that Alex Bailey, chief executive of Adur and Worthing Councils, will be seconded two days a week to be director of innovation and community infrastructure.

Last year the CCG had a £19m deficit and it is heading for a £22.3m deficit this year – although governing body papers suggest that is a “best case” outcome dependent on delivering further QIPP savings.

The forecast deficit is significantly worse than the £15.4m overspend it was asked to achieve as part of the capped expenditure process, and would mean the CCG will have to make £44.1m savings next year to achieve breakeven.
