The director responsible for helping NHS trusts deliver £1bn of productivity savings is leaving NHS Improvement, HSJ can reveal.

Paul West, who reported to NHSI’s executive director of operational productivity Jeremy Marlow, will step down from his role as director of procurement and corporate services, the regulator has confirmed to HSJ.

He took up the post in February 2017.

Mr West was responsible for improving trusts’ efficiency in procurement and corporate services with the aim of delivering up to £1bn of savings.

This included working to implement the future operating model for NHS procurement, encouraging uptake of the purchasing price index benchmarking tool, and leading the nationally contracted products programme.

NHSI did not say when Mr West would leave his position. The recruitment to find his successor will start shortly.

Elsewhere, two regional procurement hubs have seen changes to their leadership.

David John, chief executive of East of England Procurement Hub, retired this week after leading the organisation since its inception in 2007.

The organisation is one of four hubs that make up the Collaborative Procurement Partnership, which will buy goods in three categories on behalf of NHS trusts from October this year.

His position will be filled in the interim by procurement director Howard Rolfe.

Meanwhile, HealthTrust Europe, a purchasing organisation based in Birmingham, has appointed Dennis Robb as its chief executive officer.

Mr Robb, who was the organisation’s chief operating officer, replaces Jonathan Wedgebury, who left the organisation in spring last year.

HTE chair Ed Jones said: “Dennis has been instrumental in the transformation of the organisation.

“His passion for improving healthcare in the communities we serve coupled with his operational expertise will continue to enhance our partnerships with the NHS and commercial healthcare sector.”
