recommended following extensive research by the manufacturer of ScopeControl, Dovideq Medical. Delivery, installation and training took place on the day of installation at both sites. ScopeControl was located within the clean room, and in situ training was rolled out to technicians on their different shift patterns throughout the day. The operation of the ScopeControl unit is easy to understand and staff quickly became proficient in its use. The trial commenced at the Darlington Memorial Hospital site initially, and lasted for a period of 35 days. ScopeControl was then installed at the University North Durham site for 15 days.
Results
Information derived from the trial enabled the Trust to address all its key problem areas, as well as other beneficial information which could be used in a number of different ways. Table 3 shows the percentage of rigid endoscopes tested during the trial period that ‘passed’, were ‘advisories’ (indicating one or more inspection parameter is approaching minimum requirement), or ‘failed’ to meet the minimum requirement for use. The trial results showed an average 50% failure rate across both sites, the actual number of failed tests being 214. If it is assumed that typically 25% of the faulty scopes would have been picked up by SSD staff, and 25% of these failures would have been flagged by clinicians within the theatre

environment, this equates to a possible risk of approximately 53 instances of faulty scopes reaching theatre and needing ‘back up’ or ‘replacement’ equipment to be made available over the combined trial period of 50 days. The time taken to find replacement devices within the department (or elsewhere) was estimated to take at least 15 minutes
per occasion, therefore at least 15 minutes per day could be saved. This equates to more than 12 hours of wasted theatre time over the trial period alone spent finding replacement scopes, most likely while the patient is under anaesthesia. Based on average operating theatre running costs of £1,176 per hour (2016
