Royal Berkshire Foundation Trust has appointed Jean O’Callaghan as its chief executive.

Ms O’Callaghan is currently chief executive of Dorset County Hospital Foundation Trust and previously held the same role at Bedford Hospital Trust.

Originally from New Zealand, Ms O’Callaghan has also held the chief executive role at one of the country’s regional health bodies, the Canterbury District Health Board.

She will be taking up her new role in August, according to a trust spokeswoman.

Current chief executive Alistair Flowerdew, who has been carrying out the role on an interim basis, will be returning to his job as trust medical director.

Royal Berkshire’s previous chief executive, Ed Donald, resigned last December after four years leading the organisation.

The trust was investigated by Monitor after governance concerns, with the regulator finishing its probe in March this year.

Monitor said last August it was concerned that persistent failure to meet the accident and emergency target could signal wider governance problems at the trust.

Royal Berkshire was significantly behind target on its accident and emergency target in the early autumn, before winter pressures had taken hold more widely in the NHS. It recorded six 12-hour “trolley waits” in a single week in September, and was also performing significantly below the four hour waiting times standard.
