Great Ormond Street Hospital has appointed an interim chief executive to replace Jan Filochowski when he leaves at the end of the year.

Julian Nettel will join the trust from 1 January after 20 years’ experience at senior level in the NHS.

He has held chief executive positions in three large acute London trusts and was previously the managing director of the NHS Institute for Improvement and Innovation.

Mr Nettel was operations director at King’s Healthcare Trust before being appointed as chief executive of Ealing Hospital Trust. In 1999 he was appointed chief executive of St Mary’s Trust and was also chief executive at Barts and the London Trust.

Most recently Mr Nettel has provided consultancy support to a number of large health organisations and was interim managing director of the NHS Institute for Innovation and Improvement.

He joins Great Ormond Street Hospital after Jan Filochowski, the current chief executive, announced his retirement from the post last month.

Welcoming the new appointment, trust chair Baroness Blackstone said: “I am delighted that Julian will be joining the trust. His experience of managing large complex teaching hospitals and knowledge of the acute NHS London landscape mean that he will be invaluable.”

Mr Nettel said: “I am very excited about joining Great Ormond Street Hospital and using my knowledge and experience to help it continue to thrive as one of the world’s leading children’s hospitals. I have visited the hospital on a number of occasions and have always been impressed by the dedication of the staff and the quality of care delivered. 

“I am looking forward to working with them to further foster innovation and improve the care and treatment the hospital offers to some of the country’s sickest children.”
