Increase in sterile services department capacity and capability with minimised risk of interruption to operations

Neville Fowler, Technical Manager, Guy’s and St Thomas’ Hospital in London explains how a scoping project undertaken by the Trust, identified the need for a backup sterile services department (SSD), to provide cover and security for potential breakdowns within the hospitals current facilities.

Whilst the current facility at St Thomas’ Hospital could meet existing demand, it was decided the additional support would come from a new facility to be built in Guy’s Hospital. The current sterile services department at St Thomas’ would be refurbished, bringing it up to current legislative standards.

As an existing proven supplier to the Trust, we were selected to design, install and commission the reverse osmosis water purification package.

The ultimate aim was for the sterile services department to be shared between both Guy’s and St Thomas’ Hospital, providing increased capacity with the potential to supply services to other hospitals within the area.

Sterile services department Guy's and St Thomas' hospital

The hospital, innovative in its development, saw the opportunity to help maximise staff productivity by combining wash areas within the facility. To achieve this, it decided to have three separate workflows (all contaminated areas):

  • Main instrument wash
  • Endoscopy wash
  • Medical Disinfection Unit (MDU)

This design would allow staff to move between the areas quickly, effectively and safely, meeting demand as required and maximising the resources available.

The construction process at both sites went through a tender process. CFES Ltd were awarded the contract giving them responsibility for building the new facility at Guy’s Hospital and the refurbishment at St Thomas’.

The Trust purchased Belimed washer-disinfectors, porous load sterilisers and Getinge Lancer endoscope reprocessors directly from the manufacturers, whilst Envirogen was chosen to supply the new RO water purification system at Guy’s and to refurbish and increase output of the current equipment at St Thomas’.

Guy’s Hospital – New reverse osmosis water purification solution

To meet the pure water demand at Guy’s, Envirogen supplied a duplex RO system , which automatically operates in duty standby mode ensuring regular and equal usage between the units. This duplex design also provides coverage for any scheduled service. A 1,000 litre treated water storage tank was installed to buffer the water supply to the washer disinfectors and clean steam generators.

An EndoTherm Mini was installed to feed the two supplementary Getinge Lancer Endoscope reprocessors. The EndoTherm Mini was chosen because it is compact, reliable and cost effective.

Neville Fowler, Technical Manager, Guy’s and St Thomas’ Hospital, explained:

“Within 2 years it would pay for itself with the savings on chemicals and the reduction in staffing costs due to its automatic self sanitisation.”

The complete development of the new area at Guy’s Hospital took eight months finishing on schedule and budget.

St Thomas’ Hospital – Plant refurbishment and upgrade

As the current water purification supplier to this site, Envirogen refurbished an existing hot set RO system within the sterile services department and created a complete duplex design. As with Guy’s Hospital, an EndoTherm Mini was installed to feed the Endoscope reprocessors within the theatres department.

Neville Fowler, Technical Manager, Guy’s and St Thomas’ Hospital, said:

“What I like about the EndoTherm Mini is that we don’t have to touch them. They require minimal attention. We see the TVC results, they are always zero.”

The redevelopment of the St Thomas’ site took seven months. Again, within the allocated/planned work schedule, with all suppliers working closely together to ensure delivery dates were achieved.

PureSep Service plan contract maximises productivity

To support the water purification equipment supplied to the Guy’s and St Thomas’ the Trust chose to take a multi-year PureCare service contract with critical spares pack. This maximises productivity and prevents unplanned down time with any potential risks being identified during routine maintenance.

The sites now process >125,000 trays a year through their Sterile Services Department. The Trust has the largest dental school in the UK with 250 chairs, from which they process 2 million dental instruments a year.

Since opening the new department at Guy’s they also undertake all the Sterile Services Department work for Great Ormond Street Hospital. Additionally, the Trust is able to consider additional external work for other hospitals in the area, helping ensure the continued operation of the site and maximising the benefits and return on investment to the Trust.
