A report to Brighton & Hove City Council’s Health Overview and Scrutiny Committee said that a number of people were resigning, with many being reappointed as the progress is made in merging the ICBs.
This has been denied by NHS Sussex, which has said a mutually agreed resignation scheme was offered to staff for them to leave the organisation ahead of the future changes.
According to the Local Democracy Reporting Service, both NHS Surrey Heartlands and NHS Sussex ICBs now have a joint chair, Ian Smith, and a joint chief executive, Karen McDowell.
The chair of NHS Sussex, Stephen Lightfoot, who said that hundreds of jobs would go when the proposals were announced in July, retired at the end of September.
Both Mr Smith and Ms McDowell are already in post, while the chief executive of NHS Sussex, Adam Doyle, has become chief executive of NHS Kent and Medway.
