Central or Local: How a Multi-Site Hospital Group Used Market Research and Strategy Advisory to Decide Whether to Centralise Its Endoscope Reprocessing Operations

Endoscope reprocessing is one of the more operationally complex infection prevention challenges in an NHS endoscopy service, because the quality of the decontamination process is directly connected to patient safety, the documentation requirements are exacting, and the operational model is constrained by the scheduling demands of a busy endoscopy list that cannot wait for instruments. A multi-site trust operating four separate reprocessing units is carrying four sets of compliance obligations, four equipment maintenance responsibilities, and four sets of documentation practices, any one of which can generate a compliance gap without the others being affected.

The trust’s compliance audit had surfaced exactly this kind of inconsistency. Two sites had relatively new automated endoscope reprocessors with strong documentation systems.

The trust covered a geographic footprint that included sites of varying distances from the proposed central reprocessing location, and without independent data on how comparable trusts had managed transport timing at different inter-site distances, the endoscopy director had no basis for knowing whether her trust’s geography made full centralisation viable or whether a hybrid approach was necessary.

Key Challenges

• No independent benchmarking of compliance outcomes, operational costs, and transport logistics performance at comparable NHS multi-site trusts operating centralised and decentralised endoscope reprocessing models.
• No data on the inter-site transport turnaround times at which comparable trusts had experienced scheduling disruption from centralised reprocessing.
• An infection prevention compliance concern that the current decentralised model was generating across the four sites, with inconsistent documentation practices and ageing equipment at two locations.
• A full centralisation option that might not be operationally viable for the two most distant sites given the trust’s geographic spread.
• No structured assessment of whether a hybrid model, centralising some sites and retaining decentralised reprocessing at others, had been operationally successful at comparable trusts.
• Endoscopy director pressure to produce a reprocessing model recommendation that could be taken to the trust board alongside a capital investment case.

Endoscope reprocessing model decisions in multi-site NHS trusts are fundamentally constrained by geography. The compliance and cost benefits of centralisation are real and well-documented, but they require transport logistics that do not extend instrument turnaround beyond what an endoscopy scheduling model can absorb. The right model for a given trust is not the one that looks best on paper but the one that works within its specific site-to-site distance and procedure volume profile.
